Description

  The present invention relates to an anti-theft device that generates an alarm when a vehicle is illegally intruded or the like when a passenger is not present, or wirelessly reports that an unauthorized intrusion has occurred at a predetermined location.

  The anti-theft device for vehicles generates an alarm when unauthorized door opening, intrusion into vehicle interior, vehicle vibration, glass breakage, etc. are detected during arming (warning) This is a radio notification that there has been, and is now widely used.

  On the other hand, a remote starter that starts the engine from the outside by a transmitter has also been put into practical use. When performing remote start in a vehicle equipped with both the antitheft device and the remote starter, the antitheft device is usually armed. During the engine start. If it does so, a vehicle vibration will arise by engine starting, and since the vibration is detected by the sensor (vibration sensor etc.) of an antitheft device, a false alarm will arise.

  In order to solve this problem, there has been proposed a device that disarms the anti-theft device when the remote engine is started while the anti-theft device is armed, and then re-arms the engine when the engine stops. (For example, refer to Patent Document 1).

In addition, the anti-theft device prevents damage caused by a thief disconnecting the battery, which is the power source of the anti-theft device, during arming or alarming, disabling the anti-theft device, and then reconnecting the battery to steal the vehicle. Therefore, if the security mode is stored in a non-volatile memory such as an EEPROM, and the stored contents of the EEPROM is in the arming mode or alarm mode when the antitheft device is activated, the thief Many devices are equipped with an alarm function at the time of starting that an alarm is generated when it is determined that the connection has been removed and reconnected (see, for example, Patent Document 2).

The anti-theft device 1 has a keyless entry function that performs lock control, and performs door lock / unlock control of the vehicle, door opening / closing control, and alarms when there is intrusion into the passenger compartment by unauthorized means. In response to a request signal from the antitheft transmitter 3, arming / disarming control, vehicle door lock / unlock control, and the like are performed.
The antitheft transmitter 3 has a lock button L and an unlock button U. When the lock button L is pressed, security set (arming) is performed, and when the unlock button U is pressed, security reset (disarm) is performed.

  When the remote starter 2 receives the engine start request signal by pressing the start button of the remote starter transmitter 4, the remote starter 2 outputs a remote start start signal to the antitheft device 1 via the line L1, and then the IG When the ACC is turned on to the ACC line 52 of the system line, the IG is turned on to the IG line 51, the STAT on signal (predetermined period) is output to the starter line 50, the engine is started, and the engine stop request signal is received by pressing the stop button. The ACC and IG of the IG system line are turned off, the engine is stopped, and a remote start end signal is output to the antitheft device 1 via the line L1.

In the configuration shown in FIG. 1, the transmitter 4 of the remote starter 2 is a dedicated transmitter, but the transmitter 3 of the antitheft device 1 can also be used. When the transmitter is also used, the ID of the transmitter is registered in both the anti-theft device 1 and the remote starter 2 or the remote starter 2 is connected to the remote starter 2 via the communication line from the anti-theft device 1 via the communication line. Information is transmitted, and lock / arming and engine start, unlock / disarming and engine stop are identified by a difference in operation of a transmitter button or by separate buttons.
Further, the anti-theft device 1 and the remote starter device 2 can be configured integrally, and if configured integrally, only one transmitter is required. Furthermore, it is possible not to incorporate the keyless entry function in the anti-theft device 1, and in this case, the transmitter button is an arming button and a disarm button.

  On the other hand, in the anti-theft device 1, the courtesy SW 31 that detects the open / closed state of the door, the hood SW 32 that detects the open / closed state of the hood, the door can be opened by any method other than an authorized method, or the vehicle interior has been intruded. SW and sensor outputs such as an intrusion sensor 33 to detect, a vibration sensor 34 to detect vehicle vibration, an IGSW 35 to detect the on / off switching state of the ignition switch, a lock position SW 36 to detect door lock and unlock, etc. A lock motor 37 that drives a door lock mechanism that locks and unlocks the door, a siren 38 that performs an alarm operation at the time of alarm, a hazard lamp 39, a monitor lamp 40 provided on the dashboard, and the like are connected. .

  The courtesy SW 31 detects the opening / closing of the driver's seat door, the passenger seat door, the rear door, and the trunk, and is provided at each door and trunk, but only one is shown as a representative in FIG. Further, the intrusion sensor 33 detects, for example, a disturbance of the frequency of the sound wave or the radio wave when the ultrasonic wave or the radio wave is spread around the vehicle interior and the glass is broken or a person moves in the vehicle interior. The vibration sensor 34 detects the vibration of the vehicle when a person gets into the vehicle interior or tilts the vehicle to tow the vehicle.

The anti-theft device 1 is composed of a microcomputer 11, an EEPROM 12, an antenna, etc. composed of a CPU, ROM, RAM, etc., and the microcomputer 11 controls each part of the hardware of the anti-theft device 1, and an EEPROM 12, which is a nonvolatile memory, is a security mode. Memorize etc.
The microcomputer 11 is always supplied with power from the battery 42, takes one of the following modes, and stores the mode information in the EEPROM 12.
(1) Unsafe mode This mode does not detect theft. When the antitheft device 1 receives an unlock request signal (or disarm request signal, the same applies hereinafter) from the antitheft transmitter 3, the unsafe mode is entered. . In addition, the warning mode can be set according to other conditions, such as when it is determined that a key is present by a key insertion detection SW (not shown) or when ignition is turned on by the IGSW 35.

(2) Warning mode When the anti-theft device 1 receives a lock request signal (or an arming request signal, the same applies hereinafter) from the anti-theft transmitter 3, the alarm mode is entered when all doors are closed and locked. In the meantime, 40 is blinked to inform the outside of the vehicle that theft is on alert.

(3) Alarm mode When any of the following conditions is established, the alarm mode is set and an alarm is generated for a predetermined time. This alarm is performed by an alarm by the siren 38 and the hazard lamp 39 and a monitor lamp 40 (flashing at a shorter cycle than during warning).
(I) When the courtesy SW 31 or the hood SW 32 is turned on in the warning mode and the opening of the door, hood, trunk, or the like is detected. (Ii) When the detection signal is received from the intrusion sensor 33 or the vibration sensor 34 in the warning mode. (Iii) When the content stored in the EEPROM 12 is read in the initial routine after the power is turned on and the warning mode is stored. When the microcomputer 11 receives a remote start signal from the remote starter 2 in the warning mode, at least the start is completed. The non-warning mode is set for a predetermined time corresponding to the time until the operation is performed, and the warning mode is set again after the predetermined time has elapsed.

On the other hand, the remote starter 2 is similarly provided with a microcomputer 21 composed of a CPU, ROM, RAM, etc., and outputs such as a courtesy SW31, a hood SW32, an IGSW35, and an output of an alternator L terminal 41 that outputs a high level when the engine is started. In addition, an IG system line is connected.
The remote starter transmitter 4 is provided with a transmission / reception circuit (not shown), a start button, and a stop button, and an “NG” lamp for notifying start failure and a “start” lamp for notifying start completion. ing.

Next, the operation of the remote starter 2 will be described with reference to the flowchart of FIG. 2 and the operation waveform diagram of FIG.
The microcomputer 21 of the remote starter 2 always executes the program shown in the flowchart of FIG. 2. When this program is started, first, the microcomputer 21 receives a transmission code from the remote starter transmitter 4 or not. If it is determined that the transmission code is not received, the process is terminated. If it is determined that the transmission code is received, the received ID code is stored in the memory (not shown). By comparing with the regular ID code set and registered in the above, it is determined whether or not it matches the regular ID code (step 102). If it is determined that the received ID code and the regular ID code do not match, the microcomputer 21 terminates the processing. If it is determined that the received ID code matches the regular ID code, the microcomputer 21 is remotely started by the received function code. It is determined whether or not the command from the device transmitter 4 is a start request (step 103).

If it is determined that the command from the remote starter transmitter 4 is a start request, the microcomputer 21 determines whether or not the engine start condition is satisfied (step 104).
That is, the microcomputer 21 detects the courtesy SW 31, the hood SW 32, the IGSW 35, a parking SW (not shown) that detects that the shift lever is in the parking position, and a stop SW (not shown) that detects that the brake is in an operating state. Check whether the engine is in a safe state from the outputs of various switches and sensors such as the hood closed and the shift lever in the parking position, the door closed, the side brake on, the IG off, and the brake off. It is determined whether or not.

If any of the starting conditions is not satisfied, the microcomputer 21 transmits the answer back 1 to the remote starter transmitter 4 (step 105). The answerback 1 causes the remote starter transmitter 4 to be “NG”. The lamp lights up in yellow. Thereby, the user can recognize that the vehicle is not in a safe state, for example, the door is open.
On the other hand, when all the start conditions are satisfied, the microcomputer 21 outputs the remote start start signal shown in FIG. 3B to the antitheft device 1 through the line L1 (step 106), and then the ACC in the IG system line. An ACC-on output is performed on the signal line, and an ACC relay (not shown) that supplies power to the ACC circuit of the vehicle is turned on (step 107). Next, the microcomputer 21 outputs an IG signal to the IG signal line in the IG system line, and turns on an IG relay (not shown) that supplies power to the ignition circuit of the vehicle (step 108).

Thereafter, the microcomputer 21 determines whether or not 2 seconds have elapsed since the IG was turned on in order to wait for the power supply to stabilize (step 109), and when 2 seconds elapsed, as shown in FIG. ST start output is performed on the starter signal line in the line, and a starter start relay (not shown) for driving a starter motor to start the engine is turned on (step 110).
Next, the microcomputer 21 determines whether or not 3 seconds have passed since the ST was turned on (step 111). After 3 seconds, the ST output was turned off (step 112), and then the engine was started by an input from the alternator L terminal 41. It is determined whether the process is completed (step 113).

  If it is determined in step 113 that the engine has been started, the microcomputer 21 sets the value C of the start counter to 0 (step 114), and then transmits the answerback 2 to the remote starter transmitter 4 (step 115). Since the remote starter transmitter 4 is turned on by the answerback 2, the user can recognize that the engine start has been completed.

If it is determined in step 113 that the engine has not been started, the microcomputer 21 adds 1 to the value C of the start number counter (step 116), and then determines whether the value C of the start number counter is greater than three. Determination is made (step 117). If the value C of the starting number counter is 2 or less, the microcomputer 21 returns to step 109 and starts the engine again. If the value C of the starting number counter is larger than 3, the value C of the starting number counter is set to 0 ( Step 118). Next, the microcomputer 21 transmits the answer back 3 to the remote starter transmitter 4 (step 119), and then turns off the remote start start signal output to the line L1, that is, the remote start end signal. Is output to the anti-theft device 1 to notify the end of the remote start (step 120).
Since the remote starter transmitter 4 lights the “NG” lamp in red by the answerback 3, the user can recognize that the engine has failed to start.

On the other hand, if it is determined in step 103 that the command from the remote starter transmitter 4 is not a start request, the microcomputer 21 determines whether the command from the remote starter transmitter 4 is a stop request (step). 121). If it is determined that the command from the remote starter transmitter 4 is not a stop request, the microcomputer 21 ends the process, and if it is determined that the command from the remote starter transmitter 4 is a stop request, FIG. As shown in b), the remote start start signal output to the line L1 is turned off, that is, the remote start end signal is output, thereby notifying the antitheft device 1 of the remote start end (step 122). ).
In this embodiment, the anti-theft device 1 is notified of the start and end of the remote start by turning on and off the remote start signal. However, the anti-theft device 1 is notified by a code at the start and end of the remote start. It is also possible to transmit the remote start start signal and the end signal by other methods.

  In addition to the stop request from the transmitter 4 as the engine stop condition, the remote starter 2 may add other conditions such as a door or hood being opened, a brake being stepped on, or the like. In this case, a determination step of “satisfaction condition established?” Is added next after NO is determined in step 101. If YES, the process proceeds to step 122, and if NO, the process is terminated. In this way, not only the transmitter but also the door opening or the like outputs a remote start end signal and stops the engine.

  After notifying the end of the remote start, the microcomputer 21 turns off the IG output (step 123), turns off the ACC output, and executes the engine stop process (step 124). Next, the microcomputer 21 transmits the answerback 4 to the remote starter transmitter 4 (step 125). The answerback 4 causes the remote starter transmitter 4 to turn off the “start” lamp. It can be recognized that the engine has been started.

Next, the operation of the antitheft device 1 will be described with reference to the flowcharts of FIGS. 4A and 4B and the operation waveform diagram of FIG.
The microcomputer 11 of the anti-theft device 1 always executes the main program shown in the flowcharts of FIGS. 4A and 4B. When this program is started, the microcomputer 11 first transmits from the anti-theft transmitter 3. It is determined whether or not a code has been received (step 201), and if it is determined that a transmission code has been received, the received ID code is compared with a regular ID code set and registered in a memory (not shown). Then, it is determined whether or not it matches the regular ID code (step 202). If it is determined that the received ID code and the regular ID code match, it is determined whether the command from the antitheft transmitter 3 is a lock request based on the received function code (step 203).

  If it is determined that the command from the antitheft transmitter 3 is a lock request, the microcomputer 11 determines whether all the doors are closed based on the output of the courtesy SW 31 (step 204). If it is not closed, the microcomputer 11 flashes the answerback 1, for example, the hazard lamp 39 three times, thereby notifying the user that the door has not been locked and that security has not been set ( Step 205).

  If it is determined in step 204 that all the doors are closed, the microcomputer 11 outputs a lock driving signal to the lock motor 37 to lock the door (step 206), and then all the doors are locked by an input from the lock position SW36. It is determined whether or not (step 207). If any of the doors is not locked, the microcomputer 11 performs the answer back 1 in the same manner as described above, and notifies the user that the door has not been locked and that security has not been set (step 205). .

  If it is determined in step 207 that all the doors are locked, the microcomputer 11 sets the alert mode to RAM (not shown) (step 208), and then turns the answerback 2, for example, the hazard lamp 39 once. By blinking, the user is informed that the door is locked and security is set (step 209), and the monitor lamp 40 starts blinking to inform the outside of the vehicle that theft is being alerted ( Step 210).

  On the other hand, if it is determined in step 203 that the command from the anti-theft transmitter 3 is not a lock request, the microcomputer 11 determines whether the command from the anti-theft transmitter 3 is an unlock request based on the received function code. (Step 211). If it is determined that the command from the antitheft transmitter 3 is an unlock request, the microcomputer 11 outputs an unlock drive signal to the lock motor 37 to unlock the door (step 212). Next, the microcomputer 11 sets the no alert mode to the RAM (step 213), and then blinks the answer back 3, for example, the hazard lamp 39 twice, so that the door is unlocked by the user, Notifying that the reset has been made (step 214), the monitor lamp 40 is turned off (step 215).

  If it is determined in step 201 that the transmission code is not received from the anti-theft transmitter 3, and if the ID code received in step 202 does not match the regular ID code, the anti-theft transmission is performed in step 211. When it is determined that the command from the machine 3 is not an unlock request, when answer back 1 is performed at step 205, when the monitor lamp 40 starts blinking at step 210, or when the monitor lamp 40 is turned off at step 215 In that case, the microcomputer 11 determines whether or not the operation mode stored in the RAM is the alert mode (step 216).

  If it is determined that the operation mode is the alert mode, the microcomputer 11 determines whether or not the theft is detected by input from the courtesy SW31, the hood SW32, the intrusion sensor 33, and the vibration sensor 34 (step 217). If detected, the operation mode stored in the RAM is set to the alarm mode (step 218). When the mode is set to the alarm mode at step 218, when it is determined at step 216 that the mode is not the alert mode, or when it is determined at step 217 that the theft has not been detected, the microcomputer 11 is stored in the RAM. It is determined whether or not the operation mode has been changed by comparing the operation mode with the operation mode stored in the EEPROM 12 (step 219). If it is determined that the operation mode has been changed, the operation mode is stored in the RAM. The operation mode is stored in the EEPROM 12 (step 220).

  Next, the microcomputer 11 determines whether or not the operation mode stored in the RAM is the alarm mode (step 221). If the operation mode is determined to be the alarm mode, the microcomputer 11 determines that the siren 38 and the hazard lamp 39 The alarm is output by the alarm by and the blinking of the monitor lamp 40 in a short cycle (step 222). Next, the microcomputer 11 determines whether or not 30 seconds have elapsed from the start of the alarm (step 223). If it is determined that 30 seconds have elapsed from the start of the alarm, the microcomputer 11 stops the alarm (step 224) and stores it in the RAM. The set operation mode is set to the alert mode (step 225).

When the mode is set to the warning mode at step 225, when it is determined at step 221 that the mode is not the alarm mode, or when it is determined at step 223 that 30 seconds have not elapsed since the alarm start, the microcomputer 11 It is determined whether or not a remote start start signal is received from the starter 2 via the line L1 (step 226). If it is determined that a remote start start signal is received from the remote starter 2, it is stored in the RAM. It is determined whether or not the operating mode being set is the alert mode (step 227).
As shown in FIG. 3D, when receiving the remote start signal when the operation mode is the alert mode, the microcomputer 11 sets the operation mode stored in the RAM to the no alert mode (step 228). Thereafter, the value T of the no-warning mode duration timer is set to 15 seconds (step 229).

  If the timer is set in step 229, if it is determined in step 226 that a remote start start signal has not been received from the remote starter 2, or if it is determined in step 227 that the operation mode is not a warning mode, the microcomputer 11 determines whether or not the duration timer value T is greater than 0 (step 230). If it is determined that the timer value T is greater than 0, the timer value T is counted down for a predetermined time (step 231). Thereafter, the value T of the persistence timer is stored in the EEPROM 12 (step 232).

  Next, the microcomputer 11 determines whether or not a remote start end signal has been received from the remote starter 2 (step 233). If it is determined that the remote start end signal has not been received from the remote starter 2, the microcomputer 11 continues. It is determined whether or not the timer value T has become 0 (step 234), and if the duration timer value T has become 0, that is, 15 is set after receiving the remote start signal and setting the no-warning mode. When the second has elapsed, as shown in FIG. 3D, the microcomputer 11 sets the operation mode stored in the RAM to the alert mode (step 235).

If the remote start end signal is received 15 seconds after the remote start start signal is received and the no-warning mode is set, the microcomputer 11 stores the duration timer value T and the EEPROM 12. After the value T is set to 0 (step 236), the operation mode stored in the RAM is set to the alert mode (step 235).
Then, when the operation mode is set to the warning mode in step 235, it is determined in step 230 that the duration timer value T is smaller than 0, or in step 234, the duration timer value T is determined not to be 0. If so, the microcomputer 11 ends the program and starts the next main program, and again determines whether or not a transmission code has been received from the antitheft transmitter 3 (step 201).

Next, the operation at the start of the anti-theft device 1 such as when the power supply voltage drops due to engine start-up or when the battery is reconnected by a thief will be described with reference to the flowchart of FIG.
When the power supply is restored, the microcomputer 11 of the anti-theft device 1 starts the initial program shown in the flowchart of FIG. 5. When this program is started, the microcomputer 11 first performs normal initialization processing (step 301). Then, the stored contents of the EEPROM 12 are read out and it is determined whether or not the stored operation mode is the alert mode (step 302). If the operation mode stored in the EEPROM 12 is not the alert mode, the microcomputer 11 reads the operation mode and the value of the duration timer T stored in the EEPROM 12 and sets them in the RAM (step 303). On the other hand, when the operation mode stored in the EEPROM 12 is the warning mode, the microcomputer 11 sets the warning mode in the RAM, reads the value of the duration timer T from the EEPROM 12, and sets it in the RAM (step 304). Thereafter, the microcomputer 11 starts the main program shown in FIGS. 4-1 and 4-2, and determines whether or not a transmission code is received from the antitheft transmitter 3 (step 201).

  Since the microcomputer 11 of the anti-theft device 1 operates as described above, it enters a warning mode, and a thief breaks the battery and reconnects with the warning mode stored in the EEPROM 12 in steps 219 and 220 of the main routine. Then, since the warning mode is stored in the EEPROM 12, the warning mode is set in step 304 of the initial routine of FIG. 5, and therefore an alarm is immediately generated in steps 221 and 222 of the main routine.

Further, in the alert mode, when a remote start start signal is received from the remote starter 2, the no alert mode is set in steps 226 to 228, and the set no alert mode is stored in the EEPROM 12 in steps 219 and 220. In step 229, counting of the no-warning mode duration timer is started, and in step 232, the value T of the no-warning mode duration timer is stored in the EEPROM 12.
In this embodiment, the no-warning mode is stored in the EEPROM 12 in steps 219 and 220. However, it is also possible to store the no-warning mode information in the EEPROM 12 in the next step after step 228.

Thereafter, even if remote start is performed, the battery voltage does not decrease, and if the microcomputer 11 of the antitheft device 1 continues to operate without being reset, the timer continues counting in steps 230 and 231 and 15 seconds have elapsed (step 234) or when a remote start end signal is received from the remote starter 2 (step 233), the original warning mode is returned at step 235.
As shown in the flow chart of FIG. 2, the time of 15 seconds for the no-warning mode is a time in anticipation of the remote start being repeated three times, and is 10 when the remote start is repeated twice. If the remote start is only once, it may be set to 5 seconds.

  On the other hand, when the battery voltage drops due to remote start and then returns, the microcomputer 11 of the antitheft device 1 is once reset and then activated, the stored contents of the EEPROM 12 are checked at step 302 of the initial routine shown in FIG. However, at this time, since the stored content of the EEPROM 12 has already been changed to the no-warning mode before the start-up, the transition to the warning mode in step 304 is not executed.

  At this time, the operation mode stored in the EEPROM 12 in step 303, that is, the no-warning mode is set in the RAM of the microcomputer 11, and the value T of the no-warning mode duration timer is set in the RAM of the microcomputer 11. Since the timer continues counting in steps 230 and 231 of the above, similarly to the above, when 15 seconds have elapsed (step 234) or when the remote start end signal is received from the remote starter 2 (step 233), the original is returned in step 235. Return to the alert mode.

Further, in the alarm mode, when a remote start start signal is received from the remote starter 2, it does not pass through step 228, so it is not set in the no-warning mode, and the stored contents of the EEPROM 12 are stored in steps 217 to 220. Remain in the alarm mode.
Therefore, when the thief disconnects and reconnects the battery in this state (that is, during an alarm), or when the battery voltage drops due to a remote start and the microcomputer of the antitheft device is started after the battery voltage is lowered, step 221 of the main routine is started. At 222, an alarm is generated immediately.

  As described above, when a remote engine start command is received during the alarm mode, the alarm mode is set before the engine is started and the alarm mode is set again after the engine is started. It is possible to prevent malfunction of the alarm function at the time of activation due to the decrease.

In the first embodiment, when there is a remote start request in the alert mode, the alarm is in the no alert mode for a predetermined time, so that a false alarm due to the battery voltage drop due to the remote start can be prevented. During this time, the theft detection function by courtesy SW etc. does not work.
In order to solve this problem, the warning mode is originally in the above-mentioned predetermined time, and if the theft is detected by the courtesy SW during this predetermined time, the warning mode can be immediately set to the warning mode. It is preferable that the alarm mode is generated by suddenly setting the alarm mode.

Hereinafter, the operation of the microcomputer 11 in the case where the theft is detected by the courtesy SW or the like during the predetermined time when the no-warning mode is set will be described with reference to the flowchart of FIG. However, the system configuration is the same as in FIG. 1, and the operation up to step 226 of the flowchart of FIG. 6 is the same as the operation of the flowchart shown in FIG.
Further, the flowchart of FIG. 6 is obtained by inserting a theft detection step 237 between steps 232 and 233 of the flowchart of FIG. 4-2. The operation up to step 232 is the same as the operation of the flowchart shown in FIG. Therefore, the description up to step 232 is also omitted.

If the theft is detected by input from the courtesy SW31, the hood SW32, the intrusion sensor 33, and the vibration sensor 34 in step 237 within 15 seconds of the maximum unsafe mode duration after receiving the remote start signal, the microcomputer 11 After the value T of the continuous timer and the value T stored in the EEPROM 12 are set to 0 (step 236), the operation mode stored in the RAM is set to the alert mode (step 235). As a result, the alarm mode is set in steps 217 and 218 of the next routine, so that an alarm is immediately generated in steps 221 and 222. Here, in step 237, the intrusion sensor 33 and the vibration sensor 34 are also used to detect theft, but this is applied to the case of a vehicle with a small amount of vehicle vibration due to engine start.
Note that the alert mode setting at this time is performed without looking at normal setting conditions such as closing all doors and locking all doors, and no answer back is performed.

Further, the flowcharts shown in FIGS. 7A and 7B show the microcomputer 1 when the alarm is generated by immediately setting the alarm mode when the theft SW or the like is detected during the predetermined time when the alarm mode is set. When the theft is detected at the theft detection step 237 in the flowchart shown in FIG. 6, the process proceeds to step 218.
Similarly to the above, the system configuration is the same as in FIG. 1, and the operation up to step 232 and the operation after step 233 are the same as the operations of the flowcharts shown in FIGS. 4-1 and 4-2. Is omitted.

  If the theft is detected by input from the courtesy SW31, the hood SW32, the intrusion sensor 33, and the vibration sensor 34 in step 237 within 15 seconds of the maximum unsafe mode duration after receiving the remote start signal, the microcomputer 11 Since the value T of the continuous timer and the value T stored in the EEPROM 12 are set to 0 (step 238), the process proceeds to step 218 and the operation mode stored in the RAM is set to the alarm mode (step 218). In steps 221, 222, an alarm is immediately generated.

  As described above, if a theft is detected while receiving the remote start signal while in the no-warning mode, either immediately set the warning mode and enable the alarm mode, or suddenly the alarm mode. Can be set to generate an alarm.

In the above embodiment, since the start point of the no-warning mode duration is set only when the remote start signal is received, it is necessary to store the information of the no-warning mode duration in the EEPROM in consideration of the influence of the battery voltage drop.
If the starting point of the unwarranted mode duration is the time when the remote start start signal is received and the operation is started when the power is turned on, the information of the unwarned mode duration need not be stored in the EEPROM.

The flowcharts shown in FIG. 8 and FIG. 9 show the flowcharts of the main routine and the initial routine that show the operation of the program that makes it unnecessary to store the information on the duration of the unsafe mode in the EEPROM. Since the operation up to step 226 in the flowchart of FIG. 8 is the same as the operation of the flowchart shown in FIG. 4A, the flowchart and the description thereof are omitted.
Further, the flowcharts of FIGS. 8 and 9 delete steps 232 and 236 of the flowchart shown in FIG. 6 and, in the flowchart of the initial routine, a step of activating an alert mode duration timer if remotely started ( Steps 307 and 308) are added, and the operation up to step 231 in the flowchart of FIG. 8 is the same as that of the flowchart shown in FIG.

  If the theft is detected by input from the courtesy SW31, the hood SW32, the intrusion sensor 33, and the vibration sensor 34 in step 237 within 15 seconds of the maximum unsafe mode duration after receiving the remote start signal, the microcomputer 11 Immediately, the operation mode stored in the RAM is set to the alert mode (step 235). As a result, the alarm mode is set in steps 217 and 218 of the next routine, so that an alarm is immediately generated in steps 221 and 222.

  On the other hand, as shown in the flowchart of FIG. 9, the microcomputer 11 of the anti-theft device 1 performs the normal initialization process (step 301), and then reads and stores the stored contents of the EEPROM 12, as shown in the flowchart of FIG. It is determined whether or not the operating mode is the alert mode (step 302). If the operation mode stored in the EEPROM 12 is not the warning mode, the microcomputer 11 sets the operation mode stored in the EEPROM 12 in the RAM (step 305). If the operation mode stored in the EEPROM 12 is the warning mode, an alarm is issued. The mode is set to RAM (step 306).

Next, the microcomputer 11 determines whether or not it has been remotely started (step 307). If it is determined that it has been remotely started, the value T of the no-warning mode duration timer is set to 15 seconds (step 308). Thereafter, the microcomputer 11 starts the main program and determines whether or not a transmission code is received from the antitheft transmitter 3 (step 201).
Whether or not the engine is remotely started is determined by storing the engine operating information in the EEPROM 12 upon receipt of the remote start signal or by turning on the keyless IG on by the input from the key insertion detection SW or IGSW 35. It can be determined by making a determination.

  In this way, since the process of storing the value of the no-warning mode duration timer in the EEPROM in each routine becomes unnecessary, the operation can be speeded up, and if the microcomputer of the antitheft device is not reset by remote start, If the microcomputer is reset 15 seconds after the start signal is received and the microcomputer is reset, the alarm mode is restored when 15 seconds have elapsed since the start of the start.

On the other hand, if theft is detected in the no-warning mode after remote start as in the above embodiment, an intrusion sensor or vibration sensor generates an output due to vehicle vibration caused by engine start, resulting in a false alarm There are things to do.
For this reason, it is possible to prevent false alarms by detecting theft only with sensors whose outputs are not affected by vehicle vibrations such as courtesy SW and hood SW in the no-warning mode after remote start.

The flowcharts shown in FIG. 10 and FIG. 11 show the flowcharts of the main routine and the initial routine showing the operation of the program which detects theft only by the sensor whose output is not influenced by the vehicle vibration. Since the operation up to step 226 of the flowchart of FIG. 10 is the same as the operation of the flowchart shown in FIG. 4A, the flowchart and the description thereof are omitted.
Further, since the operation up to step 228 in the flowchart of FIG. 10 is the same as the operation of the flowchart shown in FIG.
In this embodiment, as shown in FIG. 12 (d), the duration of the no-warning mode is not 15 seconds from the start of the remote start, but a period from the start of the remote start until the engine stops.

  When receiving the remote start signal from the remote starter 2 in the alert mode, the microcomputer 11 sets the no alert mode in steps 226 to 228 and sets the remote control in-progress flag in the EEPROM 12 (step 239). The no-warning mode information set in step 228 is stored in the EEPROM 12 in steps 219 and 220.

  Next, the microcomputer 11 determines whether or not the remote control is being performed by checking whether or not the remote control flag of the EEPROM 12 is set (step 240). If it is determined that the engine is not under remote control, the program is terminated. If it is determined that the engine is under remote control, it is determined whether or not the door or hood is opened by input from the courtesy SW 31 and the hood SW 32 ( Step 241).

  If it is determined that the door or hood is not open, the microcomputer 11 determines whether or not a remote start end signal has been received from the remote starter 2 (step 233), and a remote start end signal is received from the remote starter 2. If it is determined that it has not been received, the program is terminated, and if it is determined that a remote start end signal has been received from the remote starter 2, the remote control in-progress flag of the EEPROM 12 is cleared (step 242) and then stored in the RAM. Is set to the alert mode (step 235), and the program is terminated.

On the other hand, if it is determined in step 241 that the door or hood is open, the microcomputer 11 immediately sets the operation mode stored in the RAM to the alert mode (step 235).
As a result, the alarm mode is set in steps 217 and 218 of the next routine, so that an alarm is immediately generated in steps 221 and 222.
If it is determined in step 241 that the door or hood is open, it is possible to shift to step 218 and immediately set the alarm mode. In addition, when the door stop or the hood open is included in the engine stop condition of the remote starter 2, a remote start end signal is output if the thief opens the door improperly. In this case, in step 241 or step 233 At the time when either of them is determined to be YES first, the warning mode is set at step 235. The same applies to the other embodiments.

  At the time of initializing after the power is restored, the microcomputer 11 of the anti-theft device 1 starts the program shown in FIG. 11 and performs a normal initialization process (step 301). Then, the stored contents of the EEPROM 12 are read and stored. It is determined whether or not the operating mode is the alert mode (step 302). If the operation mode stored in the EEPROM 12 is not the warning mode, the microcomputer 11 stores the operation mode stored in the EEPROM 12 in the RAM (step 305). If the operation mode stored in the EEPROM 12 is the warning mode, an alarm is issued. The mode is set to RAM (step 306).

As described above, the intrusion sensor and the vibration sensor are not detected during the remote control, so that the intrusion sensor and the vibration sensor are output due to the vehicle vibration caused by the engine start in the no-warning mode after the remote start. It is possible to prevent a false alarm caused by issuing a warning.
In the above embodiment, the remote control in-progress flag is set in the EEPROM 12 in step 239. However, steps 239 and 242 are deleted, and the key insertion detection SW and IGSW 35 are used to determine whether the keyless IG is ON in step 240. By doing so, it is possible to determine that the remote control is being performed.

  In the above embodiment, an alarm is generated immediately when a theft is detected in the unsafe mode after the remote start. However, in the unsafe mode after the remote start, the output is generated in the vehicle vibration of the courtesy SW, the hood SW, etc. If a theft is detected only by an unaffected sensor, the information is stored in the EEPROM, the EEPROM content is checked again when the alarm mode is set, and an alarm is immediately generated if the theft detection is stored. it can.

The flowchart shown in FIG. 13 is a flowchart of the main routine showing the operation of the program that generates an alarm when the alarm is generated again when the alarm mode is set again when the theft is detected only by the sensor whose output is not affected by the vehicle vibration. Although the operation up to step 226 in the flowchart of FIG. 13 is the same as that of the flowchart shown in FIG. 4A, the flowchart and the description thereof are omitted.
Further, the operations up to step 232 and steps 233 to 236 in the flowchart of FIG. 13 are the same as those of the flowchart shown in FIG.

After receiving the remote start signal, the microcomputer 11 determines whether or not the door or hood has been opened from the closed state for a maximum duration of 15 seconds (step 243). If it is determined that the door or hood is opened, the door 12 or the hood opening information is stored in the EEPROM 12 (step 244).
When the warning mode is set in step 235, the microcomputer 11 determines whether or not door or hood opening information is stored in the EEPROM 12 (step 245), and if the door or hood opening information is not stored. If it is determined, the program is terminated, and if it is determined that door or hood opening information is stored, an alarm mode is set (step 246).

Therefore, when a remote start start signal is received from the remote starter in the alert mode, the no alert mode is set in steps 226 to 228, and the count of the no alert mode duration timer T is started in step 229. The value of T is stored in the EEPROM 12 at step 232.
The non-warning mode information set in step 228 is stored in the EEPROM 12 in steps 219 and 220. However, the non-warning mode information may be directly stored in the EEPROM 12 in the next step of step 228.

Then, during the unsafe mode by remote operation, the door or hood is checked in step 243, and when the closed → open state is detected, the information is stored in the EEPROM 12.
After that, when the warning mode is reset in step 235, the stored contents of the EEPROM 12 are checked in step 245. If the door or hood opening information is stored, the alarm mode is set in step 246. Occurs.
If the information in the EEPROM 12 is also checked in the theft detection step in step 217, the alarm mode is set in step 218, so steps 245 and 246 are unnecessary.

  As described above, when a theft is detected only by a sensor whose output is not affected by vehicle vibrations such as courtesy SW and hood SW in the no-warning mode after the remote start, the information is stored in the EEPROM 12, so that the warning again. When the mode is set, the contents of the EEPROM 12 are checked, and if the theft detection is stored, an alarm can be generated immediately.

Further, the flowchart shown in FIG. 14 shows the operation of the program in which the information is stored in the EEPROM when the theft is detected only by the sensor whose output is not affected by the vibration of the vehicle such as the courtesy SW and the hood SW in the fourth embodiment. However, the operation up to step 226 of the flowchart of FIG. 14 is the same as the operation of the flowchart of FIG. 4 except that the contents of the EEPROM 12 are also confirmed at step 217 of the flowchart of FIG. 4-1. Therefore, the flowchart and description thereof are omitted.
Further, the operation up to step 240 in the flowchart of FIG. 14 is the same as that of the flowchart shown in FIG.

In step 243, it is determined whether the door or hood has been opened from the closed state. If it is determined that the door or hood has been opened from the closed state, the microcomputer 11 stores the door or hood opening information in the EEPROM 12 (step 244).
Next, the microcomputer 11 determines whether or not a remote start end signal has been received from the remote starter 2 (step 233), and if it is determined that the remote start end signal has not been received from the remote starter 2, the program When it is determined that the remote start end signal has been received from the remote starter 2, the remote control in-progress flag of the EEPROM 12 is cleared (step 242), and then the operation mode stored in the RAM is set to the warning mode. (Step 235).
The flowchart of the initial routine is the same as that in FIG.

Accordingly, when a remote start start signal is received from the remote starter 2 in the alert mode, as shown in FIG. 15D, the no alert mode is set, and the no alert mode is maintained while the engine is operating. When the remote start end signal is received or when the engine is stopped for some reason such as door opening, the mode immediately shifts to the warning mode.
When the alarm output by the remote start is detected, sensor outputs such as doors, hoods and the like that are not affected by engine vibrations are checked, and when a theft action such as door opening is detected, it is stored in the EEPROM. Since the contents of the EEPROM 12 are also confirmed in the theft detection at step 217 in the flowchart of FIG. 4A, the alarm mode is entered if the door opening information is stored in the EEPROM 12 when the remote control is finished and the mode is changed to the warning mode. An alarm is output immediately.

  Furthermore, it is possible to prevent false alarms by providing two modes as the warning mode. As in the conventional warning mode, the first warning mode that responds to all sensors and battery reconnection, the battery reconnection, and A sensor that generates an output due to the influence of vehicle vibration, for example, an intrusion sensor, a second warning mode that does not respond to the vibration sensor, a first warning mode is set at the time of arming by the transmitter, and the engine is stopped at the time of remote start Set to the second alert mode.

The flowcharts shown in FIGS. 16-1, 16-2, and 17 show the flowcharts of the main routine and the initial routine that show the operation of the antitheft device when two modes are provided as the alert mode. .
Similar to the above, the system configuration is the same as in FIG. 1, and the operation up to step 248 in the flowchart of FIG. 16-1 is the same as in FIG. 4 except that the first warning mode is set in step 247. Since this is the same as the operation of the flowchart shown in FIG. 1, the description is omitted, and step 248 and subsequent steps will be described.

  The microcomputer 11 of the anti-theft device 1 determines whether or not the operation mode stored in the RAM is the first warning mode (step 248), and if it is determined that the operation mode is the first warning mode, the courtesy SW31, It is determined whether or not the theft has been detected based on inputs from the hood SW 32, the intrusion sensor 33, and the vibration sensor 34 (step 217). When the theft is detected, the microcomputer 11 sets the operation mode stored in the RAM to the alarm mode (step 218). If the mode is set to alarm mode in step 218, if it is determined in step 248 that the mode is not the first alert mode, or if it is determined in step 217 that theft has not occurred, the microcomputer 11 is stored in the RAM. It is determined whether or not the operation mode has been changed by comparing the operation mode stored in the EEPROM 12 with the operation mode stored in the EEPROM 12 (step 219). If the operation mode has been changed, it is stored in the RAM. The operation mode is stored in the EEPROM 12 (step 220).

  Next, the microcomputer 11 determines whether or not the operation mode stored in the RAM is the alarm mode (step 221). If the operation mode is determined to be the alarm mode, the microcomputer 11 outputs an alarm (step 222). ). Next, the microcomputer 11 determines whether or not 30 seconds have elapsed from the start of the alarm (step 223). If it is determined that 30 seconds have elapsed from the start of the alarm, the microcomputer 11 stops the alarm (step 224) and stores it in the RAM. The operated mode is set to the first alert mode (step 249).

  If the operation mode is set to the first warning mode in step 249, if it is determined in step 221 that the operation mode is not the alarm mode, or if it is determined in step 223 that 30 seconds have not elapsed since the start of the alarm, The microcomputer 11 determines whether or not a remote start start signal is received from the remote starter 2 (step 226). If it is determined that the remote start start signal is received from the remote starter 2, it is stored in the RAM. It is determined whether the operating mode is the first alert mode (step 250).

If it is determined that the operation mode is the first warning mode, the microcomputer 11 sets the operation mode stored in the RAM to the second warning mode (step 251). The second alert mode set in step 251 is stored in the EEPROM 12 in steps 219 and 220.
When the operation mode is set to the second warning mode at step 251, when it is determined at step 226 that the remote start start signal is not received, or at step 250, it is determined that the operation mode is not the first warning mode. In that case, the microcomputer 11 determines whether or not the operation mode stored in the RAM is the second alert mode (step 252).

  If it is determined that the operation mode is the second alert mode, the microcomputer 11 determines whether or not the door or hood is opened by input from the courtesy SW31 and the hood SW32 (step 241), and the door or hood is opened. If it is determined that it is not, it is determined whether a remote start end signal is received from the remote starter 2 (step 233). If it is determined that the remote start end signal is not received from the remote starter 2, the program is terminated. If it is determined that the remote start end signal is received from the remote starter 2, the microcomputer 11 is stored in the RAM. After setting the operation mode to the first alert mode (step 253), the program is terminated.

On the other hand, if it is determined in step 241 that the door or hood is open, the microcomputer 11 immediately sets the operation mode stored in the RAM to the first alert mode (step 253).
As a result, the alarm mode is set in steps 217 and 218 of the next routine, so that an alarm is immediately generated in steps 221 and 222.
If it is determined in step 241 that the door or hood is open, it is possible to shift to step 218 and immediately set the alarm mode.

  Then, at the initial time after the power is restored, the microcomputer 11 of the anti-theft device 1 starts the program shown in FIG. 17 and performs a normal initialization process (step 301). Then, the stored contents of the EEPROM 12 are read and stored. It is determined whether or not the operating mode is the first alert mode (step 309). If the operation mode stored in the EEPROM 12 is not the first warning mode, the microcomputer 1 sets the operation mode stored in the EEPROM 12 in the RAM (step 305), and the operation mode stored in the EEPROM 12 is the first warning mode. In the case of, the alarm mode is set in the RAM (step 306).

  Accordingly, when the microcomputer 11 of the antitheft device 1 is reset after being reset after the battery voltage is lowered by remote start and is started after being reset, the stored contents of the EEPROM 12 are checked at step 309 of the initial routine of the flowchart of FIG. However, at this time, since the stored contents of the EEPROM 12 are changed to the second warning mode in steps 251 and 220 of the main routine of the flowcharts of FIGS. No migration is performed.

  Further, during engine operation by remote control (during engine start and after start completion), as shown in FIG. 18 (d), the second warning mode is set until a remote start end signal is received. When the opening of the door or the hood is detected, the first warning mode is set in steps 241 and 253, and the warning mode is set in steps 217 and 218. However, in the second warning mode during engine operation, the intrusion sensor 33 and the vibration sensor are set. Since the output 34 is not detected, it is possible to prevent a false alarm due to the intrusion sensor or the vibration sensor generating an output due to the vehicle vibration caused by the engine start.

  In the present embodiment, the second warning mode is set while the engine is operating. However, the second warning mode may be set until the start of the engine is completed, and the first warning mode may be returned after the start is completed. In this case, step 233 in FIG. The start completion is determined by the remote starter 2 determining start completion based on the output of the alternator L terminal 41 and outputting the start completion information to the antitheft device 1 via the line L1.

  In the above embodiment, the first warning mode is set when the transmitter is armed, and the second warning mode is set until the engine is stopped at the time of remote start, but the first warning mode is set when the transmitter is armed. At the time of remote start, the warning mode can be set until the start is completed, the second warning mode can be set until the engine is stopped after the start is completed, and the first warning mode can be returned after the engine is stopped.

  The flowchart shown in FIGS. 19 and 20 is a flowchart of the main routine showing the operation of the program in the case of setting to the no-warning mode until the start is completed at the time of remote start and setting to the second warning mode until the engine stops after the start is completed. FIG. 19 is a flowchart of the initial routine. Since the operation up to step 226 of the flowchart of FIG. 19 is the same as that of the flowchart shown in FIG. explain.

When the microcomputer 11 determines whether or not a remote start start signal is received from the remote start device 2 via the line L1 (step 226), and determines that the remote start start signal is received from the remote start device 2 Then, it is determined whether or not the operation mode stored in the RAM is the first alert mode (step 250).
As shown in FIG. 21 (d), when the operation mode is the first alert mode and the remote start start signal is received, the microcomputer 11 sets the operation mode stored in the RAM to the no alert mode (step 254). Next, the microcomputer 11 sets the value T of the no-warning mode duration timer to 15 seconds (step 255), and then sets the remote start flag in the EEPROM 12 (step 256).

  When the remote start flag is set at step 256, when it is determined at step 226 that the remote start start signal is not received from the remote starter 2, or when it is determined at step 250 that the operation mode is not the first warning mode The microcomputer 11 determines whether or not the value T of the continuous timer is greater than 0 (step 257), and if it is determined that the timer value T is greater than 0, the timer value T is counted down for a predetermined time. (Step 258). Next, the microcomputer 11 determines whether or not the door or hood has been opened from the closed state (step 259), and if it is determined that the door or hood has been opened from the closed state, stores the door or hood opening information in the EEPROM 12. (Step 260).

  If it is determined in step 259 that the door or hood has not been opened from closing, or if the door or hood opening information is stored in step 260, the microcomputer 11 determines whether or not the value T of the duration timer has become zero. (Step 261), when the value T of the duration timer becomes 0, that is, when 15 seconds have elapsed since the remote start start signal was received and the no warning mode was set, FIG. ), The microcomputer 11 sets the operation mode stored in the RAM to the second alert mode (step 262). Next, the microcomputer 11 determines whether or not door or hood opening information is stored in the EEPROM 12 (step 263). If it is determined that the door or hood opening information is stored, the microcomputer 11 sets an alarm mode ( Step 264).

  When the alarm mode is set at step 264, when it is determined at step 257 that the timer value T is 0 or less, when it is determined at step 261 that the duration timer value T is not 0, or at step 263, a door or If it is determined that the hood opening information is not stored, the microcomputer 11 determines whether or not a remote start end signal has been received from the remote starter 2 (step 265), and sends a remote start end signal from the remote starter 2 If it is determined that it has been received, the operation mode stored in the RAM is set to the first alert mode (step 266), and then the remote start flag stored in the EEPROM is cleared (step 267).

  Next, the microcomputer 11 determines whether or not the operation mode is the second warning mode (step 268). If the microcomputer 11 determines that the operation mode is the second warning mode, it determines whether or not the door or the hood is open. (Step 269). If it is determined that the door or hood is open, the microcomputer 11 sets an alarm mode (step 270). If it is determined that the door or hood is not open, or if the operation mode is the second operation mode in step 268, If it is determined that the mode is not the alert mode, the program is terminated and the next main program is started, and it is again determined whether or not a transmission code is received from the antitheft transmitter 3 (step 201).

  When the microcomputer 11 is activated, the microcomputer 11 starts the initial routine program shown in FIG. 20 and performs a normal initialization process (step 301). Then, the stored contents of the EEPROM 12 are read and the stored operation mode is stored. Is determined to be in the first alert mode (step 309). If the operation mode stored in the EEPROM 12 is not the first warning mode, the microcomputer 1 sets the operation mode stored in the EEPROM 12 in the RAM (step 305), and the operation mode stored in the EEPROM 12 is the first warning mode. In the case of, the alarm mode is set in the RAM (step 306).

Next, the microcomputer 11 determines whether or not the remote start flag is set in the EEPROM 12 (step 310). If it is determined that the remote start flag is set, the microcomputer 11 sets the value T of the no-warning mode duration timer to 15 seconds. (Step 311). Thereafter, the microcomputer 11 starts the main program and determines whether or not a transmission code is received from the antitheft transmitter 3 (step 201).
In this embodiment, if the first warning mode is stored in the EEPROM 12 in the initial routine at the time of starting the microcomputer, the alarm mode is entered. However, the second warning mode can respond to the battery reconnection. In that case, it is possible to shift to the alarm mode by determining whether or not the first or second alarm mode is stored in the EEPROM 12 in step 309.

As described above, when the remote start signal is received from the remote starter in the first alert mode, the no alert mode is set in steps 226 to 254, and the no alert mode duration timer T starts counting in step 255. At the same time, not the value of T but the remote start flag is stored in the EEPROM 12 in step 256 as information indicating that the remote start is being executed.
The non-warning mode information set in step 254 is stored in the EEPROM 12 in steps 219 and 220. However, the non-warning mode information may be directly stored in the EEPROM 12 in the next step of step 254.

  Then, when the anti-theft device is reset due to the battery voltage drop accompanying the engine start by the remote starter during the no-warning mode duration of 15 seconds, it starts from the initial routine, but there is no mode information stored in the EEPROM 12 Since it is in the alert mode, it does not shift to the alert mode. At this time, since the remote start flag is set, the warning mode duration timer is reset to 15 seconds in steps 310 and 311, and counting is started.

Further, during the no warning mode by remote start, the door or hood is checked at step 259, and when the closed → open state is detected, the information is stored in the EEPROM 12, and after 15 seconds, the second warning mode is entered at step 262. If set, the stored content of the EEPROM 12 is checked in step 263, and if door or hood opening information is stored, the alarm mode is set in step 264 and an alarm is generated. Then, during the second warning mode until the engine is stopped after the start is completed, only the opening of the door or the hood is detected in steps 268 to 270.
If the information in the EEPROM 12 is also checked in the theft detection step in step 269, the alarm mode is set in step 270, so steps 263 and 264 are unnecessary.

In the first, second, third, fifth, and seventh embodiments described above, the maximum time required to complete the start after the remote start control is started, that is, the no-warning mode is set for 15 seconds. The remote starter is connected to the alternator L terminal. 41 detects that the start is completed, and outputs a complete explosion signal from the remote starter to the antitheft device when the start is completed, and steps 234 (FIGS. 4-2, 6, 7-2, 8, 13) and step 261 (FIG. 19) can also be set to “T = 0 or complete explosion signal reception”, so that when the engine is started in the first start operation, it is possible to immediately shift to the warning mode or the second warning mode. , Security can be improved. In this case, when YES is determined in step 234 and step 261, the timer T is cleared to 0.
The “remote start end signal” is generated when the engine is stopped, and the “complete explosion signal” is output when the engine start is completed, that is, when the engine is started.

  In the above embodiment, the duration of the unsafe mode at the time of remote start is set to the time required for the maximum number of retries (that is, 15 seconds) in consideration of the start retry time by the remote starter. When the start-up is completed, the no-warning mode continues until 15 seconds thereafter, so that the remote starter is outputting the starter-on signal or the period for further improving the security. It is preferable to set the no-warning mode only for a period in which a stabilization time is added to

Therefore, in this embodiment, when the remote starter outputs a starter on signal that is a drive signal for driving the starter motor, the starter on information is output to the antitheft device during the output period, and the antitheft device The non-warning mode is set for a predetermined time corresponding to the time of + α while receiving the on-information or the time of the starter-on signal output period + α after receiving the starter-on information.
Further, during the setting of the no-warning mode by the remote starter, the state of the door and hood is detected and stored in the EEPROM, and if the door opening is stored in the EEPROM when the warning mode is reset, an alarm is immediately generated. To do.

Since the apparatus configuration of this embodiment is the same as that shown in FIG. 1, the description thereof will be omitted. Hereinafter, the operation of the remote starter 2 will be described with reference to the flowchart of FIG. 22 and the operation waveform diagrams of FIGS.
The microcomputer 21 of the remote starter 2 always executes the program shown in the flowchart of FIG. 22. When this program is started, the microcomputer 21 first receives a transmission code from the remote starter transmitter 4 or not. If it is determined that the transmission code is not received, the process is terminated. If it is determined that the transmission code is received, the received ID code is stored in the memory (not shown). By comparing with the regular ID code set and registered in the above, it is determined whether or not it matches the regular ID code (step 102). If it is determined that the received ID code and the regular ID code do not match, the microcomputer 21 terminates the processing. If it is determined that the received ID code matches the regular ID code, the microcomputer 21 is remotely started by the received function code. It is determined whether or not the command from the device transmitter 3 is a start request (step 103).

If it is determined that the command from the remote starter transmitter 3 is a start request, the microcomputer 21 determines whether or not the engine start condition is satisfied (step 104). If the start condition is not satisfied, The microcomputer 21 transmits the answer back 1 to the remote starter transmitter 4 (step 105).
On the other hand, if all starting conditions are satisfied, the microcomputer 21 performs ACC on output (step 107) and IG on output (step 108).
The starter-on information shown in FIG. 23C is output to the anti-theft device 1 through the line L1 (step 126). After that, the microcomputer 21 performs a starter (ST) ON output as shown in FIG. 23C after a time of 100 ms (step 110).
The delay time of 100 ms is provided because the microcomputer 11 of the anti-theft device 1 receives the starter-on information and sets it to the no-warning mode as will be described later, so that the EEPROM 12 can securely store the mode information. is there. As a result, the warning mode is surely stored in the EEPROM 12 before the battery voltage drops.

  Next, the microcomputer 21 determines whether or not 3 seconds have passed since the ST was turned on (step 111), and when 3 seconds passed, the ST output was turned off (step 112), and after a time of 100 ms, the anti-theft device The starter-on information output to 1 is stopped (step 127). Thereafter, the microcomputer 21 determines whether or not the engine start is completed by an input from the alternator L terminal 41 (step 113), and when it is determined that the engine start is completed, the value C of the start number counter is set to zero. After (step 114), the answerback 2 is transmitted to the remote starter transmitter 4 (step 115).

If it is determined in step 113 that the engine has not been started, the microcomputer 21 adds 1 to the value C of the start number counter (step 116), and then determines whether the value C of the start number counter is greater than three. Determination is made (step 117). When the value C of the starting number counter is 2 or less, the microcomputer 21 returns to step 126 after 5 seconds delay (step 128), and starts the engine again. When the value C of the starting number counter is larger than 3, the microcomputer 21 starts. After the count counter value C is set to 0 (step 118), the answer back 3 is transmitted to the remote starter transmitter 4 (step 119).
As a result, when engine start fails, as shown in FIG. 24, starter-on information and starter-on signals are output up to three times.

  On the other hand, if it is determined in step 103 that the command from the remote starter transmitter 4 is not a start request, the microcomputer 21 determines whether the command from the remote starter transmitter 4 is a stop request (step). 121). If it is determined that the command from the remote starter transmitter 4 is not a stop request, the microcomputer 21 ends the process, and if it is determined that the command from the remote starter transmitter 4 is a stop request, the microcomputer 21 outputs an IG output. After turning off (step 123) and turning off the ACC output (step 124), the answerback 4 is transmitted to the remote starter transmitter 4 (step 125).

  Next, the operation of the antitheft device 1 will be described with reference to the flowchart of FIG. 25 and the operation waveform diagrams of FIGS. 23 and 24. The operation up to step 271 of the flowchart of FIG. 25 is the same as the operation of the flowchart shown in FIG. Since they are the same, the flowchart and the description thereof are omitted, and the operation after step 271 will be described.

The microcomputer 11 determines whether or not the starter-on information is received from the remote starter 2 via the line L1 (step 271). If it is determined that the starter-on information is received from the remote starter 2, the RAM 11 It is determined whether or not the operation mode stored in is a warning mode (step 227).
As shown in FIG. 23 (d), when the starter on information is received when the operation mode is the alert mode, the microcomputer 11 sets the operation mode stored in the RAM to the no alert mode (step 228). Then, the value T of the no-warning mode duration timer is set to 4 seconds (step 272).

  If the timer is set in step 272, if it is determined in step 271 that starter-on information has not been received from the remote starter 2, or if it is determined in step 227 that the operation mode is not the alert mode, the microcomputer 11 Determines whether the duration timer value T is greater than 0 (step 230). If it is determined that the timer value T is greater than 0, the timer value T is counted down for a predetermined time (step 231). The value T of the continuous timer is stored in the EEPROM 12 (step 232).

  Next, the microcomputer 11 determines whether or not the door or hood has been opened from the closed state (step 243), and if it is determined that the door or hood has been opened from the closed state, stores the door or hood opening information in the EEPROM 12. (Step 244). If it is determined in step 243 that the door or hood has not been opened from the closed state, or after storing the door or hood opening information in step 244, it is determined whether or not the value T of the duration timer has become zero (step 234) When the value T of the duration timer becomes 0, as shown in FIG. 23D, the microcomputer 11 sets the operation mode stored in the RAM to the alert mode (step 235).

Next, the microcomputer 11 determines whether or not door or hood opening information is stored in the EEPROM 12 (step 245). If it is determined that the door or hood opening information is not stored, the microcomputer 11 ends the program, Alternatively, when it is determined that the hood opening information is stored, the operation mode stored in the RAM is set to the alarm mode (step 246).
The flowchart of the initial routine is the same as that in FIG.

Since the anti-theft device of this embodiment operates as described above, when starter-on information is received from the remote starter in the alert mode, it is set to the no alert mode in steps 271, 227 and 228, and in step 272. The total time of 4 seconds, which is 3 seconds for the remote starter to output the starter-on signal and 1 second for the battery voltage stabilization time, is set as the duration of the no-warning mode. The value of the no-warning duration timer T is stored in the EEPROM 12 at step 232, and the set no-warning mode information is stored in the EEPROM 12 at steps 219 and 220.
In this four-second alert state, the state of the door or hood is detected in step 243, and when the closed → open state is detected, the information is stored in the EEPROM 12 in step 244.

  Then, when the non-warning mode duration of 4 seconds elapses, the warning mode is reset in step 235. At this time, the stored contents of the EEPROM 12 are checked at step 245, and if the door opening information is stored, the alarm mode is set at step 246 to indicate that the thief has opened the door or hood during these 4 seconds. And an alarm is generated immediately.

If the engine cannot be started with the first starter-on signal, the second-time starter-on signal and starter-on information are output after a predetermined time, and the above operation is repeated a maximum of three times.
Further, when the battery voltage is lowered and restored by remote start and the microcomputer of the antitheft device is once reset and activated, the stored contents of the EEPROM 12 are checked in step 302 of the initial routine. Since the stored content has already been changed to the unsafe mode before the operation is performed, the alarm mode is not entered.
At this time, the no-warning mode duration timer also starts counting before activation, and since a value greater than 0 is stored in the EEPROM 12, the timer T continues counting in steps 230 and 231 and the original warning mode is reached after 4 seconds. Returned to

In this embodiment, as in the above-described embodiment, when the door open is detected during the setting of the no-warning mode by remote start, an alarm is immediately generated, or the first warning mode and the first warning mode as in the sixth embodiment. 2 warning modes may be provided, the second warning mode may be set while the starter on signal is being output, and the first warning mode may be reset after the starter on signal is output.
Further, the first warning mode and the second warning mode are provided, and when the starter-on signal output is output, the second warning mode can be set until the engine is stopped.

Furthermore, in the above embodiment, communication is performed between the remote starter and the anti-theft device via the communication line L, but a system in which communication is not performed between the remote starter and the antitheft device. Is also possible.
FIG. 26 is a block diagram showing an embodiment of a system in which communication is not performed between the remote starter and the antitheft device, and a key insertion SW 43 for detecting that a key has been inserted into an ignition key cylinder (not shown). The output of the starter SW 44 for driving the starter motor 45 and the IG on signal and the starter on signal from the remote starter 2 are input to the antitheft device 1, but the other configurations are the same as in FIG. Therefore, detailed description is omitted.

  The engine control device 53 is connected to the IG line 51 as in FIG. The engine control device 53 starts operating when the ignition switch 35 is turned on, or when the IG-on output is made from the remote starter 2 to the IG line 51 to supply power. Thereafter, when the starter switch 44 is turned on or a starter-on output, that is, a starter motor drive signal is output from the remote starter 2 to the starter line 50, the starter motor 45 drives the engine. The engine control device 53 detects the rotation of the engine and starts fuel supply control and ignition control, thereby starting the engine.

The flowchart shown in FIG. 27 is a flowchart showing the operation of the anti-theft device 1 of FIG. 26, but the operation up to step 271 of the flowchart of FIG. 27 is the same as the operation of the flowchart shown in FIG. And the description thereof is omitted.
Further, since the operation of steps 227 to 246 in the flowchart of FIG. 27 is the same as that of the flowchart shown in FIG. 25, the description of steps 227 to 246 is also omitted.
If it is determined in step 271 whether a starter-on signal is received from the remote starter 2 via the starter line 50, and if it is determined that a starter-on signal is received from the remote starter 2, the microcomputer 11 It is determined whether or not a key is inserted into the ignition key cylinder based on the output of the insertion SW 43 (step 273). If it is determined that no key is inserted (no key), that is, the remote starter 2 drives the starter motor. If it is determined that a signal has been output, it is determined whether or not the operation mode stored in the RAM is a warning mode (step 227).

  In step 274, it is determined whether or not the IG ON signal is output. If it is determined that the IG ON signal is output, the microcomputer 11 determines whether or not there is a key based on the output of the key insertion SW 43 ( If it is determined that there is a key (step 275), the operation mode stored in the RAM is set to the no-warning mode (step 276).

As described above, when the starter-on signal without a key is detected, it is determined that the remote starter has output the starter-on signal, and the no-warning mode can be set. When a starter-on signal with a key is detected, it is determined that a person has turned on the starter switch 44 with the ignition key and has output a starter-on signal, and the mode does not shift to the no-warning mode. In this case, normally, when getting into the vehicle, the anti-theft device is not alerted by the transmitter, so no control is performed.
In this way, it is not necessary to communicate with the remote starter, and the configuration can be simplified.

  In addition, when the anti-theft device is turned on with the key present in steps 274 to 276, it indicates that the person has turned on the IG with the ignition key, so that the warning mode is entered, and the starter on signal is output in this state. However, the anti-theft device does not work at all. Note that steps 274 to 276 are not required when the anti-theft device is set to IG on and does not shift to the unsafe mode.
