2. Description of the Related Art Conventionally, there is a vehicle stop device for prohibiting the traveling of an unmanned vehicle. This vehicle stopping device permits or prohibits the operation of an electronic control unit (hereinafter abbreviated as "ECU") which is a control device for an internal combustion engine of a vehicle, and a device such as a starter motor, thereby allowing the internal combustion engine to operate. Control the presence or absence of the operation of. The vehicle stop device operates, for example, in conjunction with the operation of inserting the ignition key into the key cylinder,
Including an indicating device corresponding to one-to-one, when there is an instruction from the corresponding indicating device, the operation of the internal combustion engine is permitted,
Prohibit operation at other times.

For this reason, the vehicle stopping device and the indicating device, which correspond to each other, store in advance a specific permission confirmation signal, for example, the same code signal. When the indicating device allows the vehicle stopping device to operate the internal combustion engine, a permission confirmation signal is given to the vehicle stopping device. The vehicle stop device determines whether or not the permission confirmation signal of the corresponding instruction device and the given permission confirmation signal match. Only when they match, the ECU and the starter motor are allowed to operate. Prohibit operation of the device.

Further, conventionally, there is a remote starter for starting an internal combustion engine in an unmanned vehicle by a remote instruction from the outside of the vehicle for so-called warm-up operation of the vehicle. In a vehicle that uses both a remote starter and a vehicle stop device, in order to perform a remote start operation of an internal combustion engine, it is necessary to allow the vehicle stop device to operate the starter motor and the ECU before starting the starter motor. . Therefore, the remote starter, when the start of the internal combustion engine is remotely instructed, first generates a remote permission confirmation signal, which is the same as the permission confirmation signal from the instruction device of the vehicle stop device, and supplies it to the vehicle stop device. Allow the device to operate the starter motor and ECU. Then, the starter motor and the ECU are operated to start the internal combustion engine.

This remote starter is often added later to existing vehicles as a so-called option. When this existing vehicle has a vehicle stop, it is necessary to copy the vehicle stop code signal in order for the remote starter to generate the remote acceptance confirmation signal described above.
In order to install the remote starter as an option, it is preferable that the remote starter is installed while maintaining the structure of the components of the existing vehicle stop device at the time of installation, but the existing vehicle stop device guides the code signal to the outside of the device. Since there is often no means, it is difficult to copy the code signal by simply adding the remote starter to the existing vehicle stop device.

The electronic device 1 is a device for controlling an internal combustion engine mounted on a vehicle body, and includes a vehicle stopping device for a vehicle stopping operation and a remote starting device for a remote starting operation. This is a device that is used in combination with operation. In the vehicle stop operation, the traveling of the vehicle is permitted or prohibited by permitting or prohibiting the operation of the internal combustion engine body 3 of the vehicle (referred to as “E / G” in the drawing). In the remote start operation, the internal combustion engine body 3 is operated in an unmanned vehicle by remote control from the outside of the vehicle for so-called warm-up operation.
To start. Further, the electronic device 1 has a plurality of operation modes including an execution mode for executing the vehicle stop operation and the remote start operation, and a setting mode described later, and switches the operation mode by an operation of the vehicle driver. be able to.

The electronic device 1 includes an immobilizer control means 6, an oscillation / detection means 7, and a detection switch 8 as constituent parts inside the vehicle of the vehicle stop device, and an indicating device 16 as constituent parts outside the vehicle. The remote starter includes a starter control unit 11, a switching unit 12, and an operating unit 13 as internal components of the vehicle, and a transmitter 17 as an external component of the vehicle. The instruction device 16 and the transmitter 17 can be carried by the driver of the vehicle. The components 6 to 8 and 11 to 13 inside the vehicle of the electronic device 1 are attached to the inside of the vehicle in association with the components that control the operation of the internal combustion engine body 3 of the vehicle. As components related to the internal combustion engine body 3, there are an internal combustion engine control means 21 (referred to as “E / G control” in the drawing), a starter motor 22, and a key means 23.

The immobilizer control means 6 includes an instruction device 16
The operation permission signal is generated and the operation of the internal combustion engine control device 21 is permitted only when a permission confirmation signal described later, for example, a code signal given from the above-mentioned signal, matches a specific signal described later.
The oscillating / detecting means 7 and the indicating device 16 are so-called transponder type transceivers. Starter control means 11
When a remote instruction operation is instructed from the transmitter 17, first, a resonance signal described later including an acceptance confirmation signal is given to the immobilizer control means 6 to allow the operation of the internal combustion engine control means 21, and then the internal combustion engine control means 21. 21 and the starter motor 22 are operated to start the internal combustion engine body 3. Further, the starter control means 11 instructs the signal storage operation described later by the driver operating the operation means 13,
The permission confirmation signal from the pointing device 16 is introduced to make a copy.

The internal combustion engine control means 21 is realized by a so-called electronic control unit (ECU), and controls, for example, the fuel injection amount and the fuel injection timing with respect to the internal combustion engine body 3, and the ignition timing to the air-fuel mixture, The operating state of the internal combustion engine body 3 is maintained at a predetermined state. The starter motor 22 forcibly rotates the crankshaft of the internal combustion engine body 3 that is stopped to start the internal combustion engine body 3.

The key means 23 is constituted by including a portable ignition key 24 and a rotatable key cylinder 25, and the key cylinder 25 works together with a so-called ignition switch. When the key cylinder 25 is rotated with the ignition key 24 inserted in the key cylinder 25, the ignition switch is turned on, and the electronic components associated with the internal combustion engine body 3 and the internal combustion engine control means 21, via the switch. Electric power is supplied to the starter motor 22.

The detailed structure of the vehicle stopping device and the vehicle stopping operation of the internal combustion engine control means 21 using the indicating device 16 will be described below.

The detection switch 8 is provided inside the key cylinder 25, and the key cylinder 25 is provided with an ignition key 2.
It is detected whether or not 4 is inserted. When inserted, a vehicle start signal for instructing the start of the internal combustion engine body 3 is generated. The vehicle start signal is sent to the immobilizer control means 6 which will be described later, via the lead wire 26.

The immobilizer control means 6 is realized by a microcomputer for an immobilizer and has a one-to-one correspondence with a specific indicating device 16. The control means 6 includes a start signal generation means 31, a signal confirmation means 32, and a memory 33. The activation signal generation means 31 (referred to as "activation generation" in the drawing) and the signal confirmation means 32 constitute a processing means 34 which is realized by a microcomputer. The immobilizer control means 6 is activated when the vehicle start signal from the detection switch 8 is given. After the start-up, the start-up signal generation means 31 first generates a start-up signal and supplies it to the oscillation / detection means 7 via the conductor 36. The start-up signal is a signal for instructing to start the operation of the oscillation / detection means 7, and is also a signal for instructing the switching timing of oscillation and detection operation described later.

The above-mentioned switching means 12 is interposed in the conducting wire 36 and is realized by a changeover switch, for example. This conductor 36
By means of the switching means 12 the upstream part 37 of the signal flow.
And a downstream portion 38 of the signal flow. Details of the switching means 12 will be described later. The switching means 12 is used when the confirmation determination operation in the remote start operation, which will be described later, is not being performed, that is, during the normal operation, and the upstream and downstream portions 37, 3 are provided.
8 is electrically connected.

The oscillating / detecting means 7 includes a high-frequency signal generating means 41 (referred to as "RF generation" in the drawing), a detecting means 42 and a changeover switch SW1, and a power supply 45.
It is possible to operate only while the power is supplied from. Also,
A coil L1 is provided near the key cylinder 25 in association with the oscillation / detection means 7. The changeover switch SW1 electrically connects one terminal of the coil L1 and one of the high frequency signal generation means 41 and the detection means 42.

Further, the indicating device 16 of the vehicle stopping device is
The resonance signal generating means 46 (which is referred to as "resonance" in the drawing) realized by a resonance circuit and the coil L2 are included, and are provided inside the ignition key 24, for example. Coil L1
Is realized by, for example, a pair of coils wound around an annular core arranged near the insertion hole of the key cylinder 25 and arranged to face each other on one diameter line. The coil L2 is realized by a coil wound around a core that is magnetically coupled to the core of the coil L1.

The oscillation / detection means 7 is a start signal generation means 3
It operates from 1 to the above-mentioned activation signal. This activation signal is also given to the changeover switch SW1. The change-over switch SW1 has, for example, one contact on the output terminal side of the high-frequency signal generation means 41 and the input terminal side of the detection means 42, which conducts in synchronization with the high level and the low level of the start signal which is a rectangular pulse signal. Alternately switch to the other contact. As a result, the oscillation / detection means 7 performs an oscillating operation when conducting to one contact side, and performs a detecting operation when conducting to the other contact side. In this way, the oscillation / detection means 7 periodically repeats the oscillation operation and the detection operation based on the activation signal.

In the oscillating operation, the high frequency signal is applied from the high frequency signal generating means 41 to the coil L1 via the changeover switch SW1. This high-frequency signal is, specifically,
It is an oscillating current obtained by scanning the frequency in a predetermined frequency range.

When a high frequency signal is applied to the coil L1,
The resonance signal generation means 46 of the pointing device 16 resonates with respect to the electromotive current generated in the coil L2, generates a resonance signal, and sends it to the immobilizer control means 6 via the oscillation / detection means 7. Specifically, when the resonance signal generating means 46 resonates with the electromotive current, the current flowing through the coil L1 also changes according to the resonance frequency. The oscillation / detection means 7 is a coil L
The resonance frequency obtained from the current change of 1 is regarded as the allowance confirmation signal, and is detected as the resonance signal unique to the indicating device 16.
Using such transponder type transmitting / receiving means,
When the resonance signal is transmitted and received, the power supply can be removed from the resonance signal generation means 46.

In the detection operation, the resonance signal from the coil L1 is sent to the oscillation / detection means 7 and given to the detection means 42 via the changeover switch SW1. Specifically, the detection means 42 first amplifies the resonance signal and then separates the resonance signal into a resonance data signal and a resonance clock signal. The resonance data signal is a signal representing the resonance frequency detected from the change in the current of the coil L1. The resonance clock signal is a clock signal for synchronizing the resonance data signal. Hereinafter, the resonance data signal and the resonance clock signal are collectively referred to as a resonance signal. Such a resonance signal is converted into a digital signal and then given to the signal confirmation means 32 of the immobilizer control means 6 through the conductor 46.

As described above, in this embodiment, the oscillation / detection means 7 and the pointing finger 16 constitute confirmation signal generating means, and based on the activation signal from the activation signal generating means 31, the permission confirmation signal is generated. And a resonance data signal is sent to the signal confirmation means 32.

The signal confirmation means 32 uses the resonance signal including the allowance confirmation signal and determines whether or not the allowance confirmation signal matches the specific signal, so that the pointing device 16 corresponds to the electronic device 1 in a one-to-one manner. The confirmation / determination operation is performed to determine whether the device is an authorized device. Specifically, the resonance clock signal is used to synchronize with the resonance data signal, and it is determined whether or not the detected resonance frequency represented by the resonance data signal matches a predetermined specific frequency stored in the memory 33. The specific frequency is the same as the resonance frequency peculiar to the resonance signal generating means 46 of the indicating device 16 that corresponds to the immobilizer control means 6 on a one-to-one basis, and corresponds to the above-mentioned specific signal.
When the resonance signal matches the specific signal by such a determination operation, it is determined that the resonance signal is a signal obtained from the legitimate pointing device 16, and when the resonance signal does not match, a resonance signal from another pointing device 16 that does not correspond. , Or that a completely different signal is obtained. This specific signal is stored in the memory 33 in advance when the immobilizer control means 6 is shipped, for example.

When the resonance signal that matches the specific signal is given, the signal confirmation means 32 of the immobilizer control means 6 generates an operation permission signal for instructing the operation permission of the internal combustion engine control means 21, and the control means. Give to 21. On the other hand, when it is determined that the resonance signal that does not match the specific signal is given, the signal confirmation means 32 causes the internal combustion engine control means 2 to operate.
An operation prohibition signal for instructing the operation prohibition 1 is generated and given to the control means 21. When the operation allowance signal is given, the internal combustion engine control means 21 becomes operable when the operation instruction from the key means 23 or the operation instruction in the remote start operation described later is given, and the operation prohibition signal is given. Is given, the operation at the above time is prohibited. By such an operation, the operation permission / prohibition of the internal combustion engine control means 21, that is, the operation permission / prohibition of the internal combustion engine body 3 is controlled.

The detailed structure of the remote starting device for the internal combustion engine body 3 will be described below. The above-mentioned starter control means 11 and the transmitter 17 correspond to each other on a one-to-one basis and exchange signals by wireless communication. The transmitter 17 constitutes a remote starting means.

The starter control means 11 is realized by, for example, a microcomputer. For example, when the vehicle is stopped and the ignition key 24 is removed from the key cylinder 25, the control means 11 is always supplied with electric power to operate. The control means 11 includes a receiving means 62, a pseudo signal generating / transmitting means 64 (in the drawing, “pseudo generation”), memories 63 and 67, and a setting means 70. Receiving means 42 and pseudo signal generating and sending means 64
May be realized by a single processing means. Also,
An antenna 61 is provided along with the receiving means 62.

The receiving means 62 confirms the ID signal of a remote start signal and a remote stop signal, which will be described later. The pseudo signal generating and feeding means 64 causes the immobilizer control means 6 to perform a confirmation determination operation for allowing the operation of the internal combustion engine control means 21 when performing the remote start operation. The memory 63 is
It is realized by a readable / writable memory and stores a pseudo resonance signal as a pseudo permission confirmation signal in a confirmation determination operation of a remote start operation described later. The setting means 70 performs a setting operation for setting the pseudo resonance signal in the memory 63. Details of each operation will be described later.

Further, the pseudo signal generating / transmitting means 64 has conductors 65, 66, 68 for transmitting signals. The lead wire 65 is
It is provided to lead a remote start signal, which will be described later, to the signal confirmation means 32, and is directly connected to the conductor wire 26. Conductor 66
Is provided for introducing the activation signal from the activation signal generation means 31 to the oscillation / detection means 7 to the pseudo signal generation / feeding means 64, and is connected to the upstream side portion 37 of the conducting wire 36 via the switching means 12 described above. Connected. The conductor 68 is provided for deriving a remote start signal from a pseudo resonance signal, which will be described later, and is directly connected to the conductor 46. Further, the setting means 70 is a conductor 6
9, a conductor 69 is provided for introducing the resonance signal from the indicating device 16 into the setting means 70 and is directly connected to the conductor 46. Further, the lead wire 69 is the starter control means 1
It may be realized by a structure in which it is branched from the conductor wire 68 in 1 and the connection terminal of the conductor wire 68 and the starter control means 11 is used as an input / output terminal.

The above-mentioned switching means 12, specifically, the one-side contact 7 connected to the end of the downstream portion 38 of the conductor 33.
1 and the other contact 72 connected to the end of the conductor 66. The switching operation of the switching means 12 is controlled by the pseudo signal generating and feeding means 64, as will be described later. During the above-mentioned normal operation, the one contact 71 is always conducted.
That is, the upstream and downstream portions 37, 3 of the conductor 33.
Connect 8. As a result, during normal operation, the activation signal from the activation signal generation means 31 is given only to the oscillation / detection means 7.

The transmitter 17 has a transmitting means 51, a start switch 52 and a stop switch 53. When instructing the remote starting operation of the internal combustion engine body 3, the driver of the vehicle operates the start switch 52 to cause the transmitting means 51 to transmit a remote start signal instructing the start. Further, when the remote start operation is stopped halfway, the stop switch 53 is operated to cause the transmitting means 51 to transmit a remote stop signal. The remote start signal and the remote stop signal include I specific to the transmitter 17.
D signal is included.

The detailed operation of each means in the starter control means 11 and the remote start operation of the electronic apparatus 1 will be described below together.

The remote start signal and the remote stop signal from the transmitter 17 are received by the antenna 61 and received by the receiving means 62.
Given to. The receiving means 62 uses the ID included in each signal.
Performs signal confirmation / judgment operation. Specifically, the receiving means 62
Determines whether the ID signal included in each signal matches a regular ID signal stored in advance in the memory 63. When the ID signals do not match, it is determined that a signal from a transmitter corresponding to another electronic device or a completely different signal has been erroneously received, and the remote start operation or its stop operation is not performed. When the ID signals match, it is determined that the remote start signal from the transmitter 17 that correctly corresponds to the electronic device 1 is obtained, and the remote signal or remote instruction signal is sent to the pseudo signal generating / sending means 64. A confirmation determination operation of the remote start or stop operation is performed. By thus determining the ID signal of the signal from the transmitter 17, the remote start operation and the remote stop operation are started only when the one-to-one corresponding transmitter 17 of the electronic device 1 is operated. be able to.

As will be described later, the immobilizer control means 6 also confirms the pseudo permissive signal confirmation signal, so that confirmation of this ID signal confirmation signal can be omitted.

In the confirmation / determination operation, first, the pseudo signal generating / feeding means 64 operates the switching means 12 to change it.
The one contact 71 is switched to the other contact 72. Thereby, the upstream side portion 37 of the conducting wire 33
Is connected only to the conducting wire 66, only the starter control means 11 can introduce the activation signal, and the oscillation / detection means 7 is deactivated.

The pseudo signal generating and feeding means 64 then generates the remote start signal from the transmitter 17 and leads 65, 26.
Are sequentially given to the immobilizer control means 6.
The remote start signal is the same signal as the vehicle start signal derived from the detection switch 8. At this time, the key cylinder 2
Since the ignition key 24 is not inserted in No. 5, the vehicle start signal from the detection switch 8 is not given to the lead wire 26. Therefore, even if a remote start signal is given to the immobilizer control means 6 through the conductor 26, there is no inconvenience that the two kinds of signals are overlapped on the conductor 26 and the signal waveform is distorted. Further, when the signal from the transmitter 17 is a signal different from the vehicle start signal, the pseudo signal generating and feeding means 64 generates a remote start signal when the signal from the transmitter 17 is given to the immobilizer control means. May be given.

When the remote start signal is given, the immobilizer control means 6 treats the remote start signal in the same manner as the vehicle start signal, and causes the start signal generation means 31 to generate the start signal and lead it to the lead wire 36. Since the switching means 12 is switched to the other contact 72 side, this activation signal is given to the pseudo signal generating / feeding means 64 of the starter control means 11 via the upstream side portion 37 of the conducting wire 36 and the conducting wire 66. Therefore, even though the activation signal is derived from the activation signal generation means 31, the oscillation / detection means 7 is deactivated, so that no high frequency signal is generated.

Subsequently, the pseudo signal generation / supply means 64 includes a pseudo resonance data signal and a pseudo resonance clock signal with reference to a pseudo allowance confirmation signal stored in the memory 67 as signal storage means, for example, a set frequency. Generate a quasi-resonant signal. The pseudo resonance data signal corresponds to a pseudo permission confirmation signal. The pseudo-resonance clock signal and the pseudo-resonance data signal are signals similar to the resonance data signal and the resonance clock signal output from the oscillation / detection means 7,
Further, it is equal to the signal when the resonance frequency is the set frequency set in the memory 67. The set frequency is set to be the same as the resonance frequency, and the setting method will be described later. The quasi-resonant signal is given to the signal confirmation means 32 of the immobilizer control means 6 via the conductors 68 and 46 after a predetermined waiting time has elapsed since the start signal was introduced.

The predetermined waiting time is the oscillation / detection means 7
It is set so as to match the time required for the first oscillation operation of. This is to match the derivation timing of the pseudo resonance signal with the derivation timing of the normal resonance signal from the oscillation / detection means 7. The reason for this is as follows. The oscillation / detection means 7 alternately repeats the oscillation operation and the detection operation as described above, but these operations are always started from the oscillation operation. This is because the quasi-resonant signal is handled by the immobilizer control means 6 in the same manner as the resonant signal, so that the introduction timings of the signals must be the same.

When the quasi-resonant signal is given to the signal confirmation means 32 via the conductor 46, the oscillation / detection means 7 is stopped as described above, so that the resonance signal from the means 7 is led to the conductor 46. Not done. Therefore, the inconvenience that the two kinds of signals are overlapped on the conductor wire 46 and the signal waveform is distorted does not occur.

Signal confirmation means 3 of immobilizer control means 6
When the quasi-resonant signal is given, 2 treats the quasi-resonant signal in the same manner as the resonance signal from the detecting means 42 and performs the confirmation / determination operation. The pseudo permission confirmation signal included in the pseudo resonance signal is set to match the permission confirmation signal included in the resonance signal. Specifically, the set frequency is set to the same frequency as the resonance frequency. Accordingly, the confirmation / determination operation of the pseudo resonance signal can be performed by the same operation as the confirmation / determination operation of the resonance signal. Specifically, the execution timing of the confirmation determination operation is synchronized with the pseudo resonance clock signal to determine whether the resonance frequency represented by the pseudo resonance data signal matches the specific frequency in the memory 33.
As described above, since the waveform of the pseudo resonance signal is not disturbed on the conductor 46, the resonance frequency of the pseudo resonance data signal matches the specific frequency.

By such a determination operation, when it is determined that the pseudo permission confirmation signal and the specific frequency match, that is, when the resonance frequency and the specific frequency match, the signal confirmation means 32 generates an operation permission signal. The operation of the internal combustion engine body 3 is permitted by giving the internal combustion engine control means 21. On the other hand, when some error occurs in the pseudo-resonance signal, the signal confirmation means 32 determines that the pseudo-permission confirmation signal and the specific signal do not match, and the signal confirmation means 32 generates the operation prohibition signal to generate the internal combustion signal. By giving it to the engine control means 21, the operation of the internal combustion engine body 3 is prohibited. The failure of the confirmation / determination operation is that a large amount of noise is superimposed on the conducting wire 46, for example. There is also an error in the quasi-resonant signal itself.

When the confirmation / determination operation is completed, the pseudo signal generating / feeding means 64 switches the conducting contact of the switching means 12 from the other contact 72 to the one contact 71, and again the conducting wire 33.
The upstream side portions 37 and 38 of are connected. by this,
The state where the activation signal from the activation signal generation means 31 is given to the oscillation / detection means 7 again is restored. By such a series of operations, the key cylinder 25 is connected to the ignition key 24.
It is possible to allow the immobilizer control means 6 to operate the internal combustion engine body 3 in a state in which is not inserted.

When the operation of the internal combustion engine control means 21 is permitted by the confirmation / determination operation, the pseudo signal generation / feeding means 64 then starts the internal combustion engine body 3 by the internal combustion engine control means 21 and the starter motor 22. Start operation. Specifically, first, for example, an electric power is supplied from the power supply 45 to the internal combustion engine control means 21 and the starter motor 22 by bypassing the ignition switch which should be conducted in conjunction with the key cylinder 25. As a result, the internal combustion engine control means 21 and the starter motor 22 start operating, and the internal combustion engine body 3 is started. Further, after the internal combustion engine body 3 is started, the starter control means 11 shuts off only the power supply to the starter motor 22 and causes the internal combustion engine control means 21 to maintain the idle state of the internal combustion engine body 3.
The internal combustion engine body 3 started by such a remote start operation is stopped when the ignition key 24 is inserted into the key cylinder 25, for example. The driver of the vehicle uses the key cylinder 2 in which the ignition key 24 is inserted.
By rotating 5 to supply electric power to the starter motor 35, the internal combustion engine body 3 is restarted.

In the electronic device 1 capable of executing the vehicle stopping operation and the remote starting operation by such a series of operations, the driver merely instructs the remote starting operation of the internal combustion engine, and the vehicle stopping device is operated by the internal combustion engine main body. The internal combustion engine main body 3 can be started by allowing the operation of the internal combustion engine body 3.

The setting operation of the quasi-resonant signal in the above-mentioned remote starting operation will be described below. This setting operation is performed by the electronic device 1
Is performed before the remote start operation is performed, for example, immediately after the electronic device 1 is installed in the vehicle, and the resonance signal is stored in the memory 67 as a pseudo resonance signal. Further, the setting operation is performed in a setting mode different from the execution mode in which the vehicle stop operation and the remote start operation are performed among a plurality of operation modes preset in the electronic device 1, for example.
In the setting mode, the remote start operation and the vehicle stop operation are not executed regardless of the operation on the electronic device 1. Switching between these modes is performed by a driver of the vehicle operating the operating means 13. Specifically, the setting mode is selected and not operated only when the operating key of the operating means 13 is operated by the driver. At this time, the execution mode is selected.

When instructing the setting operation, for example, the driver operates the operation means 13 with the ignition key 24 inserted in the key cylinder 25. Operation means 13
Activates the setting means 70 in the starter control means 11 to start the setting operation. In this setting operation, specifically, the resonance frequency represented by the resonance signal is stored in the memory 67 as the set frequency.

During the setting operation, the immobilizer control means 6 and the oscillation / detection means 7 operate in the same manner as the vehicle stop operation described above, and send and receive a start signal and a resonance signal.
The setting means 70 branches and introduces the resonance signal transmitted by the conducting wire 46 via the conducting wire 69 to obtain the resonance signal. The resonance frequency of this resonance frequency is stored in the memory 67 as the set frequency of the pseudo resonance signal. When the quasi-resonant signal is set in this way, the setting operation ends by switching the operation mode to the execution mode.

Such setting operation can be carried out without changing the operations of the immobilizer control means 6 and the oscillation / detection means 7. As a result, when a remote starter including the starter control means 11 is added later to an existing vehicle stop device including the immobilizer control means 6 and the oscillation / detection means 7 to generate the electronic device 1 described above, The resonance frequency set in the vehicle stop device can be copied without changing the structure and signal flow of each means 6, 7 of the vehicle stop device.

Further, the resonance frequency from the resonance signal generating means 46 of the ignition key 24 is set in the memory 67 as the set frequency. Therefore, after that, the memory 67
The quasi-resonant signal generated based on the set frequency in
It becomes a signal for transmitting the same frequency as the resonance signal of the resonance signal generating means 46. As a result, the resonance frequency of the resonance signal as the permission confirmation signal and the set frequency of the pseudo resonance signal as the pseudo permission confirmation signal match, so that the confirmation determination operation of the vehicle stop operation and the confirmation determination operation in the remote start operation are performed. The same operation can be performed. Therefore, the remote start operation can be performed without changing the operation of the signal confirmation means 32 of the existing vehicle stop device.

The electronic device 1 having the above structure is
As described above, the remote start signal from the starter control means 11 and the pseudo resonance signal are transmitted through the conductors 26 and 46 for transmitting the vehicle start signal from the changeover switch 8 and the resonance signal from the oscillation / detection means 7. It is given to the immobilizer control means 6 via the. Therefore, these signals can be given to the control means 6 without increasing the number of input / output terminals of the immobilizer control means 6. further,
By the setting operation described above, the resonance signal can be copied without changing the structures of the immobilizer control means 6 and the oscillation / detection means 7, so that the pseudo resonance signal can be matched with the resonance signal.

Further, comparing the existing vehicle stop device with the electronic device 1 of the present embodiment, the electronic device 1 shows that the starter control means 11, the switching means 12, the operating means 13, the antenna 61 and the conducting wires 65, 66, 68. , 69 is added, and the conductor 36, which is originally one conductor, is divided into upstream and downstream portions 37, 38. The immobilizer control means 6 and the oscillation / detection means 7 have respective structures and The behavior is the same. Therefore, the electronic device 1
It can also be realized by modifying the wiring in the existing vehicle stop device and mounting the above-mentioned components for the remote start operation of the internal combustion engine. Further, the changed portion is only the wiring portion of the device, and there is no change in the structure of the immobilizer control means 6 and the oscillation / detection means 7, which are formed as a unit in a single housing, for example. Accordingly, for example, even in a factory of a vehicle dealer, it can be easily implemented only by making the above-described changes to the existing vehicle stop device.

FIG. 2 is a block diagram showing the electrical configuration of the electronic device 91 according to the second embodiment of the present invention. The electronic device 91 of the present embodiment differs from the electronic device 1 of the first embodiment only in the detailed structure of the immobilizer control means and the start control means relating to the above-described setting frequency setting operation, and the other components are the same as those of the electronic device 1 of the first embodiment. The same reference numerals are given to the components, and the description will be omitted. In the electronic device 91 of the present embodiment, the immobilizer control means itself has a plurality of specific signals, and it is possible to determine whether the given signal and each specific signal match or do not match, and the specific signal is generated after the device 91 is manufactured. It has a structure that can be additionally set. That is, the plurality of specific signals include a predetermined specific signal,
A setting specifying signal which is set later is included.

The immobilizer control means 93 has a structure similar to that of the immobilizer control means of the electronic apparatus 1 of the first embodiment, and includes a start signal generation means 31, a signal confirmation means 94, a memory 95, a setting means 96, and a conductor 97. It is configured to include.
The memory 95 functions as a signal storage means. The signal confirmation means 94 has a structure similar to that of the signal confirmation means 32 of the first embodiment, and refers to the stored contents of the memory 95 to perform the confirmation determination operation. This confirmation determination operation is similar to the confirmation determination operation of the signal confirmation means 32 of the first embodiment, except that the given signal is compared with a plurality of specific signals. Memory 95
Is realized by a readable / writable memory and stores a plurality of specific signals. The setting means 96 performs a setting operation described later.

Further, an operating means 98 is provided in association with the setting means 96. The operation unit 98 is a unit for the driver of the vehicle to instruct switching between an execution mode and a setting mode described later, and the operation unit 1 of the electronic device 1 according to the first embodiment.
3 has the same or similar structure.

The starter control means 101 is changed from the starter control means 11 of the electronic apparatus 1 of the first embodiment to the setting means 7.
Except for 0, it has a structure in which the memory 102 is included in place of the memory 67. The memory 102 includes the resonance signal generation means 4
A preset frequency that is determined separately from the resonance frequency of 6 is stored in advance when the control means 101 is shipped from the factory. The memory 102 is not limited to a readable / writable memory, and may be realized using a memory having another structure. The pseudo signal generation / supply unit 64 generates a pseudo resonance signal based on the set frequency stored in the memory 102. The details of this pseudo resonance signal are the same as those of the resonance signal except for the value of the set frequency that the pseudo resonance signal represents.

As described above, in the second embodiment, the pointing device 16 and the oscillation / detection means 7 constitute the first confirmation signal generation means, and the first permission is given in the same manner as in the first embodiment. A resonance signal is generated as a confirmation signal. Further, the memory 102 and the pseudo resonance signal generation means 64 are
The second confirmation signal generating means is configured to generate a pseudo resonance signal as the second permission confirmation signal.

The vehicle stop operation and the remote start operation of the electronic device 91 are the same as the vehicle stop operation and the remote start operation of the electronic device of the first embodiment except for the confirmation determination operation of the signal confirmation means 94. The confirmation determination operation of the signal confirmation means 94 will be described in detail below.

The memory 95 stores the first specific signal which is the same as the resonance signal and the second specific signal which is the same as the pseudo resonance signal. Specifically, the first specific signal is the first specific frequency A having the same frequency as the resonance frequency, and the second specific signal is the second specific frequency B having the same frequency as the set frequency. Second
The specific frequency B is set to the electronic device 9 by using the setting operation described later.
1 It can be set after manufacturing.

FIG. 3 is a flow chart for explaining the confirmation determination operation of the signal confirmation means 94.

When the resonance signal as the first permission confirmation signal or the pseudo resonance signal as the second permission confirmation signal is given to the signal confirmation means 94 through the lead wire 46, the signal confirmation means 94 refers to the clock signal in the signal and refers to the data. In synchronization with the signal, the confirmation / determination operation is started, and the process proceeds from step a1 to step a2. In step a2, it is determined whether the resonance signal or the pseudo resonance signal is positioned with the first specific signal. Specifically, it is determined whether or not the frequency represented by each data signal matches the first specific frequency A. If they do not match, then in step a3, it is determined whether the resonance signal or the pseudo resonance signal is positioned with the second specific signal. Specifically, it is determined whether or not the frequency represented by the data signal matches the second specific frequency B. If they do not match, the resonance signal and the quasi-resonance signal do not match any of the first and second specific signals, it is determined that the confirmation determination operation has failed, and the process proceeds to step a4. The failure of the confirmation / determination operation is due to, for example, that a large amount of noise is superimposed on the conducting wire 46, and
And the acceptance confirmation signal different from the second specific signal is given. In step a4, the signal determination means 3
2a inhibits the operation of the control means 21 by generating an operation prohibition signal and giving it to the internal combustion engine control means 21.

Further, in step a2, when each data signal matches the first specific signal, it is judged that the given signal is a resonance signal from the indicating device 16 which corresponds to the immobilizer control means 93 one to one. Then, the process proceeds to step a5.
Furthermore, in step a3, when the resonance signal data signal matches the second specific signal, it is determined that the given signal is the pseudo resonance signal from the pseudo signal generating / feeding means 64 of the starter control means 101. , Go to step a5. In step a5, the signal determining means 32a allows the operation of the control means 21 by generating an operation allowance signal and giving it to the internal combustion engine control means 21. When the operation of the control means 21 is prohibited or permitted, the processing operation of the flowchart is ended in step a6.

When different signals are given to the vehicle stopping operation and the remote starting operation by such a series of operations,
By the same confirmation and determination operation, it is possible to determine whether the operation of the internal combustion engine control means 21 is permitted or prohibited. It should be noted that when the resonance signal is sent from the indicating device 16, it is determined whether or not it coincides with a predetermined first specific signal, and when the pseudo signal sending means sends the pseudo resonance signal, it is set later. In order to determine whether or not it matches the second specific signal, the specific signal for determining the match may be switched according to the sender of the data signal.

The setting operation of the second specific signal used for the above-described signal determination operation will be described below. This setting operation is
Before the remote start operation is performed by the electronic device 91, for example, immediately after the electronic device 91 is installed in the vehicle, specifically, the set frequency of the pseudo resonance signal is copied. The setting operation is performed in a setting mode different from the execution mode in which the vehicle stop operation and the remote start operation are performed among a plurality of operation modes preset in the electronic device 91, for example. In the setting mode, the remote start operation and the vehicle stop operation are not executed regardless of the operation on the electronic device 91. Switching between these modes is performed by the driver of the vehicle operating the operating means 98. In particular,
The setting mode is selected only when the driver operates the operation key of the operation means 98, and the operation mode is selected when the operation key is not operated.

When instructing the setting operation of the second specific signal,
For example, the driver operates the operation means 98 in a state where the ignition key 24 is not inserted in the key cylinder 25. The operating means 98 activates the setting means 96 in the immobilizer control means 93 to start the setting operation.

During execution of the setting operation, the pseudo signal generating / feeding means 64 of the starter control means 101 operates in the same manner as the remote start operation described above, and derives the remote start signal to start the operation of the immobilizer control means 93. And further derive a quasi-resonant signal. The setting means 96 branches and introduces the quasi-resonant signal transmitted by the conducting wire 46 via the conducting wire 97 to obtain the set frequency represented by the quasi-resonant signal. This set frequency is stored in the memory 95 as the second specific frequency B. When the second specific frequency of the quasi-resonant signal is set in this way, the setting operation is finished by switching the operation mode to the execution mode.

When the first specific signal in the memory 95 is set only by the resonance signal generating means 46 at the time of factory shipment and is not stored in the memory 95, it is stored in the memory 95 by an operation similar to the setting operation described above. be able to. First
When instructing the setting operation of the specific signal, for example, the driver operates the operation means 98 with the ignition key 24 inserted in the key cylinder 25. The operating means 98 activates the setting means 96 in the immobilizer control means 93 to start the setting operation.

In this setting operation, like the vehicle stopping operation, the setting means 96 branches the resonance signal via the lead wire 97 in the state where the resonance signal is transmitted and received between the immobilizer control means 93 and the oscillation / detection means 7. Introduce and obtain the resonance frequency represented by the resonance signal. The resonance frequency is stored in the memory 95 as the first specific frequency A. When the first specific signal that is the same as the resonance signal is set in this way, the setting operation ends by switching the operation mode to the execution mode.

When the immobilizer control means 93 includes a structure for such a setting operation, the first and second specific signals used for the confirmation / determination operation are set after the factory shipment of the electronic device 1, for example. can do. As a result, when a remote starting device including the starter control means 101 is added later to an existing vehicle stop device including, for example, the immobilizer control means 93 and the oscillation / detection means 7 to generate the electronic device 91 described above, The set frequency set in the remote starter can be copied to the immobilizer control means 93 without changing the structure and signal flow of each means 93, 7 of the vehicle stop device.

The electronic device 91 having the above configuration
As described above, the remote start signal from the starter control means 11 and the pseudo resonance signal are the lead wires 26 for transmitting the vehicle start signal from the changeover switch 8 and the resonance signal from the oscillation / detection means 7. It is given to the immobilizer control means 93 via 46. Therefore, these signals can be given to the immobilizer control means 93 without increasing the number of input / output terminals of the immobilizer control means 93. Further, by the setting operation described above, the set frequency can be copied without changing the structures of the immobilizer control means 93 and the oscillation / detection means 7.

Further, comparing an existing vehicle stop device having a function of setting a specific frequency with the electronic device 91 of the present embodiment, the electronic device 91 shows that the starter control means 10
1, the switching means 12, the operating means 13, the antenna 61 and the conductors 65, 66, 68, and the conductor 36 that was originally one conductor, the upstream side and the downstream side part 3
The immobilizer control means 93 and the oscillation / detection means 7 have the same structure and operation, except that they are divided into 7 and 38. Therefore, the electronic device 91 can also be realized by modifying the wiring in the existing vehicle stop device and attaching the above-mentioned components for the remote start operation of the internal combustion engine. Further, the changed portion is only the wiring portion of the device, and there is no change in the structure of the immobilizer control means 93 and the oscillation / detection means 7 which are formed as a unit in a single housing, for example. Accordingly, for example, even in a factory of a vehicle dealer, it can be easily implemented only by making the above-described changes to the existing vehicle stop device.

The present invention can be implemented in the following modes. (1) An internal combustion engine body that is mounted on a vehicle body and can be remotely controlled; a key means that is mounted on the vehicle body and that generates a vehicle start signal for starting the internal combustion engine body; A remote start signal for generating a remote start signal, a confirmation signal generation unit for generating a permission confirmation signal, a signal storage unit for storing the permission confirmation signal as a pseudo permission confirmation signal, and the remote start signal based on the remote start signal. Pseudo signal generating and sending means for reading and sending the pseudo permission confirmation signal stored in the signal storage means, and operation means for storing the permission confirmation signal from the confirmation signal generating means as the pseudo permission confirmation signal. And signal confirmation means for transmitting the permission confirmation signal from the confirmation signal generation means and the pseudo permission confirmation signal from the pseudo signal generation and transmission means. , When the vehicle start signal is generated by said key means, the allowable check signal from said check signal generating means is fed to said signal confirmation means;
The signal confirmation means generates an operation permission signal that permits the operation of the internal combustion engine body when the predetermined specific signal and the permission confirmation signal match, and when the specific signal and the permission confirmation signal do not match, An operation prohibition signal for prohibiting the operation of the internal combustion engine body is generated, and when the remote start signal is generated by the remote start means, the pseudo permission confirmation signal from the pseudo signal generation and supply means confirms the signal. The signal confirmation means generates the operation permission signal when the specific signal and the pseudo permission confirmation signal match, and the signal confirmation means generates the operation permission signal when the specific signal and the pseudo permission confirmation signal do not match. When the prohibition signal is generated and the permission confirmation signal is stored as the pseudo permission confirmation signal, the confirmation signal generating means outputs the inhibition signal. Remote starter for an internal combustion engine, characterized in that contents confirmation signal is fed to the signal storage means.

(2) Key means mounted on the vehicle body for generating a vehicle start signal for starting the internal combustion engine body,
Remote starting means for generating a remote starting signal for remotely starting the internal combustion engine, confirmation signal generating means for generating a permission confirmation signal, and signal storage means for storing the permission confirmation signal as a pseudo permission confirmation signal, Pseudo signal generating and sending means for reading and sending the pseudo permission confirmation signal stored in the signal storage means based on the remote start signal,
Operation means for storing the permission confirmation signal from the confirmation signal generation means as the pseudo permission confirmation signal, the permission confirmation signal from the confirmation signal generation means, and the pseudo permission from the pseudo signal generation / feeding means. Signal confirmation means for transmitting a confirmation signal, and when the vehicle start signal is generated by the key means, the permission confirmation signal from the confirmation signal generation means is transmitted to the signal confirmation means, The signal confirmation means generates an operation permission signal for permitting the operation of the internal combustion engine body when a predetermined specific signal and the permission confirmation signal match, and the remote start signal is generated by the remote start means. Occasionally, the pseudo permission confirmation signal from the pseudo signal generation and transmission means is transmitted to the signal confirmation means, and the signal confirmation means No. and the pseudo permission confirmation signal match, the operation permission signal is generated, and when the permission confirmation signal is stored as the pseudo permission confirmation signal, the permission confirmation signal from the confirmation signal generating means is A remote starter for an internal combustion engine, which is fed to a signal storage means.

In the internal combustion engine remote starter, the signal confirmation means permits the operation of the internal combustion engine main body only when the permission confirmation signal or the pseudo permission confirmation signal given in the above-mentioned procedure matches the specific signal. As described above, the pseudo permission confirmation signal is a signal that is transmitted by reading the permission confirmation signal generated by the confirmation signal generation means in response to the vehicle start signal stored in the storage means. The pseudo permission confirmation signal and the permission confirmation signal are the same. Therefore, the internal combustion engine body can be started only when the device having the instruction means capable of generating or sending the permission confirmation signal is operated. Further, in the internal combustion engine for a vehicle including the key means, the confirmation signal generation means, and the signal confirmation means, by providing the signal storage means and the pseudo signal generation / feeding means, the remote control can be performed.

Since the pseudo permission confirmation signal and the permission confirmation signal are the same signal, when the pseudo permission confirmation signal is given, the signal confirmation means can handle the pseudo permission confirmation in the same manner as the permission confirmation signal. Therefore, regardless of whether the permission confirmation signal or the pseudo permission confirmation signal is given, the operation of the internal combustion engine body can be determined without changing the operation of the signal confirmation means.

Furthermore, when the specific signal does not match the permission confirmation signal and the pseudo permission confirmation signal, it is possible to determine whether the internal combustion engine body is not operated or the operation is prohibited.

As the pseudo permission confirmation signal, the permission confirmation signal sent from the confirmation signal generating means to the signal confirmation means is taken in, for example, from the transmission path between the both means, and the signal is copied and stored in the storage means. Get by. Thereby, the pseudo-permission confirmation signal can be obtained without changing the structures and operations of the confirmation signal generation means and the signal confirmation means.

In the remote starter for an internal combustion engine, the pseudo signal generating / sending means for remote start sends a permission confirmation signal for permitting the operation of the internal combustion engine between the confirmation signal generating means and the signal confirming means. Introduce by branching from the transmission path. Thereby, the acceptance confirmation signal can be obtained without changing the structures and operations of the confirmation signal generation means and the signal confirmation means. Further, since the pseudo permission confirmation signal is a signal equivalent to the permission confirmation signal, the confirmation determination operation of the operation permission of the internal combustion engine in the signal confirmation means should be the same operation as the device having the structure in which only the permission confirmation signal is given. You can Therefore, for example, by simply adding the structure for the remote starter and the structure for the pseudo signal generating and feeding means for copying the permission confirmation signal to the internal combustion engine for a vehicle having only the vehicle stopping device, the above-mentioned remote A startable internal combustion engine can be formed.

Is generated, and when the specific signal and the first permission confirmation signal do not match, an operation prohibition signal that prohibits the operation of the internal combustion engine body is generated. When the start signal is generated, the second permission confirmation signal is sent to the signal confirmation means, and the signal confirmation means, when the setting identification signal and the second permission confirmation signal match, the operation permission signal.

Signal confirmation means to which the first permission confirmation signal from the confirmation signal generation means and the second permission confirmation signal from the second confirmation signal generation means are sent, and the vehicle start signal is generated by the key means. At this time, the first permission confirmation signal from the first confirmation signal generation means is sent to the signal confirmation means, and the signal confirmation means matches the predetermined specific signal with the first permission confirmation signal. Occasionally, an operation permission signal for permitting the operation of the internal combustion engine body is generated, and when the remote start signal is generated by the remote start means, the second allowance confirmation signal is sent to the signal confirmation means, The signal confirming means generates the operation permitting signal when the setting specifying signal and the second permitting confirming signal match each other, and further sets the second permitting confirming signal to the setting characteristic. When stored as a signal, the remote starter for an internal combustion engine wherein the second tolerance confirmation signal from said second check signal generator means, characterized in that it is fed to the signal storage means.

In the remote starter of the internal combustion engine, as described above, when the vehicle start signal is generated, the signal confirmation means compares the first allowance confirmation signal with the predetermined specific signal,
When the remote start signal is generated, the second acceptance confirmation signal is compared with the setting specific signal. When the compared signals match in each case, the operation of the internal combustion engine body is permitted, and when they do not match, the operation is prohibited.
