Description
2317037 VEHICULAR LOAD CONTROL APPARATUS The present invention relates to
a vehicular load.
control apparatus for selectively operating a plurality of vehicular loads by using a transmitter that transmits an ID code as an air- propagating signal.
An example of vehicular load control apparatuses is a vehicular keyless entry system that employs an IC card type transmitter having an antenna (coil) for magnetic coupling, and control components provided in a driver's side door outer handle of a vehicle. The control components include an antenna (coil) for magnetic coupling with the antenna in the transmitter, and a start switch. The vehicle is also equipped with a control circuit. When a user operates the door outer handle to. disengage the door lock, the start switch is thereby switched on and off, so that the control. circuit supplies the tran smi tter with electric power in the form of a magnetic signal through the antenna. The transmitter sends the vehicle antenna an ID code in the form of a magnetic signal. If the ID code received by the antenna is correct, the control circuit operates a door lock disengaging actuator which is one of vehicular loads.
There is a demand for a capability for opening a vehicular trunk without using a key. To meet this demand, the conventional art requires that the trunk be provided with control components similar to those provided in the door outer handle, thereby causing problems of cost increases.
Accordingly, it is an object of the present invention to provide a lowcost vehicular load control apparatus that is able to selectively operate a plurality of vehicular loads using a transmitter that transmits an ID code in the form of an air-propagating signal.
According to the present invention, there is provided a vehicular load control apparatus comprising an antenna provided in a vehicle f or receiving an ID code as an airpropagating signal; a start switch operable from an external device is also provided in the vehicle; and control means including a counter function to count the number of times of operation of the start switch performed within a predetermined is length of time, the control means operating one of a plurality of vehicular loads that corresponds to a count value provided by the counter function if the ID code received by the antenna is correct.
The vehicular loads are selected in accordance with the numbers of times of operation of the start switch. Based on an ID code transmitted from a transmitter in the form of an air-propagating signal, a vehicular load selected as above is operated. Therefore, the vehicular load control apparatus of the present invention makes it unnecessary to provide control components for each vehicle load, and can be realized 2 at low costs.
The plurality of vehicular loads may include a door lock disengaging actuator and a trunk opening actuator, and the door lock disengaging actuator may be assigned with a smaller 5 count value than that assigned for the trunk opening actuator. Furthermore, the antenna may be provided in a door outer handle and the start switch may be operated by the door outer handle.
This optional construction makes it possible to open a trunk as well, using a transmitter for door lock disengagement. Since the construction requires that the trunk be merely provided with the trunk opening actuator, it can be realized at low costs. Further, since the number of times of operation of the start switch for door lock disengagement, which is frequently performed, is relatively small, there will be no degradation in operability compared with the conventional art.
The foregoing and further objects, features and advantages of the present invention will become apparent from the following description of preferred embodiments with reference to the accompanying drawings,'wherein like numerals are used to represent like elements and wherein:
Fig. 1 is a schematic block diagram of the electric construction of an embodiment of the vehicular load control apparatus of the present invention; and Fig. 2 is a flowchart illustrating the operation of the embodiment.
3 An embodiment wherein the present invention is applied to a vehicular keyless entry system will be described with reference to the drawings.
Referring to Fig. 1, an antenna 1 is provided in a driver's side door outer handle of a vehicle (not shown). Both end terminals of the antenna 1 are connected to input terminals of a control circuit 2. A door outer handle operation detecting switch (hereinafter, referred to simply as 'detecting switch) 3 is provided, as a start switch, near the door outer handle. An output terminal of the detecting switch 3 is connected to an input terminal of the control circuit 2. When the door outer handle is operated, the detecting switch 3 turns on and outputs an ON signal Sa. The detecting switch 3 turns off and stops outputting the ON signal Sa when the door outer handle is released from an operated state. The antenna 1 and the detecting switch 3 constitute control components.
The control circuit 2, made up mainly of a microcomputer, is provided with a first output terminal connected to each door lock disengaging actuator 4, that is, a vehicular load, and a second output terminal connected to a trunk opening actuator 5, that is, another vehicle load, and a third output terminal connected to a vehicular load 6 such as a room lamp, an electric door mirror retraction canceling mechanism or the like. The control circuit 2 outputs a lock disengagement instruction signal Sb, an opening instruction signal Sc and 4 an option driving instruction signal Sd to the door lock disengaging actuator 4, the trunk opening actuator 5 and the vehicular load 6, respectively, through operation described below.
The lock disengaging actuator 4 disengages each door lock when supplied with the lock disengagement instcuction signal Sb. The trunk opening actuator 5 opens the trunk when supplied with the opening instruction signal Sc. The vehicular load 6 operates when supplied with the option driving instruction signal Sd. More specifically, if the vehicular load 6 is a room lamp, the room lamp turns on. If it is a door mirror retraction canceling mechanism, the door mirrors are driven from the retracted position to the inuse position.
An IC card 7, serving as a transmitter, has a coil antenna 8, a capacitor 9, and a control circuit 10 formed of an integrated circuit (IC). The antenna 8 and the capacitor 9 are connected in parallel. Both terminals of the parallel circuit are connected to input terminals%of the control circuit 10. If the IC card 7 is placed near the driver's side door outer handle of the vehicle, the'antenna 8 becomes magnetically coupled with the antenna 1 so that magnetic signals are transmitted and received between the two antennas.
The operation of this embodiment will be described with reference to the flowchart of Fig. 2.
The operation illustrated by the flowchart of Fig. 2 is started by the detecting switch 3 turning on to output the ON signal Sa to the control circuit 2. For convenience in illustration, the flowchart includes a determining step S1 of 0IS DETECTING SWITCH ON?". That is, the control circuit 2 determines in the step S1 whether the detecting switch 3 is on, based on the presence or absence of the ON signal Sa.
Therefore, if the detecting switch 3 is off, the control circuit 2 determines "No" in the determining step S1 and repeating the step S1.
If a user operates the door outer handle provided in a driver's side door of the vehicle, the detecting switch 3 is turned on and outputs the ON signal Sa. Therefore, the control circuit 2 determines "YES" in the determining step S1 and proceeds to a processing step S2 of 'IN = 0, FLG = 111. In the processing step S2, the control circuit 2 resets the count value N of a counter (not shown) that performs a counter function, and sets a flag FLG to 1, and proceeds to a processing step S3 of "START TIMER".
The control circuit 2 starts a timer (not shown) in the processing step S3, and proceeds to a processing step S4 of "TRANSMIT POWER" in which the control circuit 2 continues to supply an alternating power to the antenna 1 until the timer completes an operation of counting a predetermined time. Then, the control circuit 2 proceeds to a processing step S5 of "START RECEIVING SIGNAL" in which the control circuit 2 establishes a state enabled for reception of the magnetic signal f rom the antenna 8 of the IC card 7. Therefore, if the user places the IC card 7 near the door outer handle, the antennas 1, 8 become magnetically coupled so that the antenna 8 receives the alternating power in the form of a magnetic signal. The capacitor 9 is thereby supplied with a directcurrent power. When the voltage between the 6 terminals of the capacitor 9 reaches a predetermined value, the IC card 7 transmits from the antenna 8 an ID code in the form of a magnetic signal.
Subsequently to the processing step SS, the control circuit 2 proceeds to a determining step S6 of "HAS TIMER TIMED OUTV' in which it is determined whether the timer has completed the predetermined time counting operation. If it is determined "NO"F the control circuit 2 proceeds to a determining step S7 of "IS SIGNAL RECEIVED?" in which it is determined whether the antenna 1 has received a magnetic signal from the IC card 7. For example, if the user places the IC card 7 near the driver's side door outer handle of the vehicle beforehand, the control circuit 2 determines "YES" in the step S7 since the capacitor 9 has been supplied with the is power in the step S4 and the ID code has been transmitted from the antenna 8. The control circuit 2 then proceeds to a determining step SS of "IS ID CODE CORRECTV'. In the determining step S8, the control circuit 2 determines whether the ID code indicated by the magnetic signal received by the antenna 1 is correct. If it is determined "YES", the control circuit 2 proceeds to a determining step S9 of 'IN = 0 or 1VI.
In the determining step S9, the control circuit 2 determines "YES" since the count value of the counter has been 7 reset to 0 in the processing step S2. Then the control circuit 2 proceeds to a processing step S10 of 'UNLOCK DOORO. In the step S10, the control circuit 2 outputs the lock disengagement instruction signal S6 to operate the.lock disengaging actuator 4, thereby disengaging each door lock of the vehicle.
Conversely to the above-described situationp'df the user keeps the IC card 7 apart from the driver's side door outer handle of the vehicle, the control circuit 2 determines ON0w in the operation of the determining step S7 since no magnetic signal transmission has been performed between the antennas 1 and 8. The control circuit 2 then proceeds to a detexmining step S11 of 'IS -DETECTING SWITCH OM in which it is.determined whether the detecting switch 3 is off. if the.user has not released the door outer handle from the operated state, the detecting switch 3 remains on, so that the control circuit 2 determines NO' in the determining step S11, and goes to a processing step S12 of 'FIG - 11 and then back to the determining step S6, thereby going in a circle though the determining steps 56, S7 and S11. and the processing step S12.
if the user releases the door outer handle from the operated state, the detecting switch 3 turns of f, so that the control circuit 2 determines OYES' in the operation of the debermining step 511 and proo to a determIning step S13 of OFLG - 1R. Since the flag FLG has been set to 1 in the processing step S2 or 512, the control circuit 2 determines "YES" in the determining step S13, and proceeds to a processing 8 step 514 of % = N + 1, FLG = W. In the processing step S14, the control circuit 2 adds 1 to the count value N of the counter to make the count value 1, and resets the f lag FLG to 0. After that, unless the detecting switch 3 is turned on, the control circuit 2 determines "NOn in the determining step S11 and repeats the determining steps S6, S7, S11 and S13.', If the user places the IC card 7 near the driver's side door outer handle while the control circuit 2 is the above-described operational state, the IC card 7 transmits from the antenna 8 the ID code in the form of a magnetic signal.
Then, the control circuit 2 determines OYESw in the operation of the determining step S7 and proceeds to the determining step S8 of IS ID CODE CORRECTV. The control circuit 2 determines in the determining step S8 whether the ID code indicated by the magnetic signal transmitted from the antenna 8 is correct. If it is determined 'YES, the control circuit 2 proceeds to the determining step S9 of wN = 0 or 1?0. Since the count value N has been set to 1 in the processing step S14, the control circuit 2 determines YES ' in the determining step S9 and proceeds to the processing step S10, in which the control circuit 2 outputs the lock disengagement instxuction signal Sb to the lock disengaging actuator 4 to unlock each door lock.
As described above, if the user keeps the IC card 7 near the driver's side door outer handle of the vehicle from the beginning or places it near the door outer handle later, the count value N of the counter becomes 0 or 1. In either case, 9 the control circuit 2 proceeds to the processing step S10, thereby disengaging each door lock of the vehicle.
However, while the control circuit 2 is going in a circle through the determining steps S6, S7, S11 and S13 (the count value N of the counter remains 1), the user may operate the driver's side door outer handle of the vehicle again (the second operation). in such a case, the detecting switch 3 turns on and outputs the ON signal Sa, so that the control circuit 2 determines nNO" in the determining step S11 and proceeds to the processing step S12 of "FLG = 1", in which the control circuit 2 sets the f lag FLG to 1. Thus, the control circuit 2 goes in a circle through the step S6, S7, S11 and S12 as long as the detecting switch 3 remains on - If the user releases the door outer handle after that, the detecting switch 3 turns off, so that the control circuit 2 determines wYESO in the operation of the determining step S11, and proceeds to step S13. Since the flag FW has been set to 1 in the processing step S12, the control circuit 2 determines "YESn in the determining step S13 and proceeds to the processing step S14.
In the processing step S14, the control circuit 2 adds 1 to the counter value of the counter to make the counter value 2, and resets the f lag FW to 0. The control circuit 2 then returns to the determining step S6 to go in a circle through the determining steps S6, S7, S11 and S13.
If the user places the IC card 7 near the driver's side door outer handle of the vehicle in this operational situation, the IC card 7 transmits its ID code from the antenna 8 in the form of a magnetic signal as described above. Then, the control circuit 2 determines nYESO in the.operation of the determining step S7 and proceeds to the determining step S8 of "IS ID CODE CORRECT?". If it is determined "YES" in this step, the control circuit 2 proceeds to the determinj,.ng step S9 of % = 0 or l?". Since the count value N has been set to 2 in the processing step S14, the control circuit 2 determines "NO" in the determining step S9 and proceeds to a determining step S15 of % =.2?N.
The control circuit 2 determines wYES" in the determining step S15 and proceeds to a processing step S16 in which the control circuit 2 outputs the opening instruction signal Sc to the trunk opening actuator 5. The trunk opening actuator 5 is thereby operated to open the trunk of the vehicle.
If the user operates the driver ' s side door outer handle of the vehicle again while the control circuit 2 is going in a circle through the determining steps S6, S7, S11 and S13 (the counter value of the counter remains. 2), the detecting switch 3 turns on and outputs the ON signal Sa, so that the control circuit 2 determines "NO" in the determining step S11 and proceeds to the processing step S12 of "FLG = 1", in which the control circuit 2 sets the flag FLG to 1. Thereby, the control circuit 2 goes in a circle through the steps S6, S7, 25 S11 and S12 as long as the detecting switch 3 remains on. If the user releases the door outer handle f rom the operated state after that, the detecting switch 3 turns off, so that the 11 control circuit 2 determines "YES" in the operation of the determining step S11 and proceeds to the determining step S13.
Since the flag FIG has been set to 1 in the processing step S12. the control circuit 2 determines "YES" in the determining step S13 and proceeds to the determining step S14.
In the processing step S14, the control circuit 2 adds 1 to the counter value of the counter to make the counter value 3, and resets the flag FLG to 0. The control circuit 2 then returns to the determining step S6 to go in a circle through the determining steps S6, S7, S11 and S13.
If the user places the IC card 7 near the driver's side door handle of the vehicle in this operational situation, the IC card 7 transmits its ID code f rom the antenna 8 in the f orm of a magnetic signal as described above. Then, the control circuit 2 determines "YES" in the operation of the determining step S7 and proceeds to the determining step SS of "IS ID CODE CORRECTV'. If it is determined "YES" in this step, the control circuit 2 proceeds to the determining step S9 of 'IN = 0 or 1VI. Since the count value N has been set to 3 in the processing step S14, the control circuit 2 determines "NO" in the determining step S9 and proceeds to a determining step S15 or 'IN = 211. Since the count value N has been set to 3 in the processing step S14, the control circuit 2 determines "No,, in the determining step S14 and proceeds to a determining step S17 of IN = 311'2111.
The control circuit 2 determines "YES" in the determining step S17 and proceeds to a processing step S18 of "OPTIONAL FUNCTION" in which the control circuit 2 outputs the option driving instruction Sd to the vehicular load 6 to operate the vehicular load 6. The vehicular load 6 is provided 12 as an optional function and connected to the third output terminals of the control circuit 2. If the vehicular load 6 is a room lamp, the room lamp is turned on due to the option driving instruction signal Sd. If the vehicular load 6 is an electric door mirror retraction canceling mechanism, the door mirrors are moved from the retracted position to thewin-use position due to the option driving instruction signal Sd.
If the timer completes the predetermined time counting operation during the cycle of the determining steps S6, S7, S11 and S13 or the determining steps S6, S7, S11 and S13, the control circuit 2 determines 'YES" in the determining step S6 and ends the operation without performing any control operation. The'control circuit 2 also ends the operation without performing any control operation, if it determines "NON in the determining step S8 of wIS ID CODE CORRECT?' or "NO" in the determining step S17 of % = 3?n.
As described above, if the counter value N of the counter for counting the number of times of operation of the detecting switch 3 in the control circuit 2 is 0 or 1, the control circuit 2 disengages each door lock of the vehicle provided that the ID code of the IC card 7 is correct. If the counter value is 2, the control circuit 2 opens the trunk of the vehicle provided that the ID code of the IC card 7 is correct. Thus, using the antenna 1 and the detecting switch 3 (control components) and the IC card 7 provided essentially for door lock disengagement, this embodiment is able to open the trunk of the vehicle as well. Since the opening actuator 5 is- substantially the only 13 requirement for the trunk, this embodiment can be realized at low costs.
Moreover, the door lock disengaging actuator 4 can be selectively operated by a user operating the driver's side door outer handle of the vehicle to turn on the detecting switch 3 (a half of one complete action of door outer handle operation) or to turn it on and off (one complete action of door outer handle operation), according to the embodiment. Therefore, the operability in door lock disengagement, which is more frequently performed than the opening of the trunk, is not degraded compared with the conventional art.
Further, according to the embodiment, the control circuit 1 is provided with the third output terminal for an optional function, and outputs from the third output terminal the option driving instruction signal Sd if the counter value of the counter becomes 3 (three complete actions of door outer handle operation). Based on the option driving instruction signal Sd, the vehicle load 6 connected to the third output terminal is operated. Therefore, it becomes possible to selectively operate a desired vehicle load 6,for example, a room lamp or a door mirror retraction,canceling mechanism, using the IC card 7 provided essentially for door lock disengagement. The embodiment thus provides great convenience in use.
The present invention is not limited to the embodiment described above with reference to the drawings, but may be modified or expanded as follows.
14 Although the lock disengaging actuator 4 and the trunk opening actuator 5 are connected to the f irst and second output terminals of the control circuit 2, other vehicle loads may instead be connected thereto.
The third output terminal of the control circuit 2 for an optional function may be provided only if it is necessary.
Furthermore, the third output terminal may be exclusively connected to a specific vehicular load.
The IC card 7, serving as a transmitter, may be provided with a switch for ID code transmission or with a battery cell as a direct- current power source.
The antennas are not limited to the above-described antennas 1, 8, but may be any type as long as the antennas are able to transmit. and receive air-propagating signals in the form of electromagnetic waves, light, ultrasonic waves, or the like. Instead of the door outer handle detecting switch 3, a touch- type start switch may be provided in a suitable site in the vehicle. 20 The present invention may be applied to not only motor vehicles but also substantially all kinds of vehicles. [Advantages of the Invention] As understood from the above description, since the vehicular load control apparatus of the invention selects a vehicular load in accordance with the number of times of operation of a start switch and operates the selected vehicular load by transmitting an ID.code in the form of an air-propagating signal from the transmitter, the apparatus makes it possible to selectively operate a plurality of vehicle loads using the transmitter that transmits an ID code without requiring control components provided for each.
vehicular load. Therefore, the vehicular load control apparatus can be realized at low costs.
In optional constructions of the vehicular load control apparatus of the invention, the plurality of vehicular loads include a door lock disengaging actuator and a trunk opening actuator, and the door lock disengaging actuator is assigned with a counter value that is smaller than that assigned for the trunk opening actuator. Further, an antenna is provided in a door outer handle, and the start switch is operated by the door outer handle. Therefore, the apparatus also allows the trunk to be opened using the transmitter provided for door lock disengagement. Since the opening actuator is substantially the.only requirement for the trunk, the apparatus can be realized at low costs. Further, since the number of times of operation of the start switch to select the door lock disengaging operation is small, there is no degradation in operability compared with the conventional art.
While the present invention has been described with reference to what is presently considered to be a preferred embodiment thereof, it is to be understood that the invention is not limited to the disclosed embodiment or constructions. To the contrary, the invention is intended to cover various 16 modif ications and equivalent arrangements included within the spirit and scope of the appended claims.
