An ID code registration process according to an embodiment will be described with reference to this flowchart. In step 1, it is confirmed whether the ignition switch 9 is turned on, that is, whether the ignition knob 30 is set to an ignition on (ON) position. If the knob 30 is in the ignition on position, the process proceeds to step 2. In step 2, it is confirmed whether or not an ID code is stored in the memory 12b. If no ID code is stored, the process proceeds to step 3 as an ID code registration mode. The process proceeds to step 15 as the processing mode.

If the ID code is not stored in the memory 12b and the mode is the ID code registration mode, an engine start permission signal is transmitted to the engine controller 15 in step 3 to permit the start of the engine. Here, when the occupant turns the ignition knob 30 to the engine start position (ST), the engine starts. In the following step 4, the rotational speed of the wheel is read from the wheel speed sensor 16. Step 5
Then, it is determined whether or not the rotation speed of the wheel is equal to or higher than the set value. If the rotational speed is equal to or higher than the set value, the process proceeds to step 6; Here, the set value of the rotation speed of the wheel is, for example, a rotation speed slightly higher than the rotation speed of the wheel when the engine is operating at the rotation speed at the time of idling. Note that the ID code registration process may be performed while the vehicle is actually running, or may be performed while the wheels are being rotated by driving the engine on a free roller for a completed vehicle test. If the rotational speed of the wheel is lower than the set value, it is checked in step 14 whether or not the ignition switch 9 is off. If not, the process returns to step 4 and repeats the above-described processing. If the ignition switch 9 is off, proceed to step 11,
The engine is stopped by the engine controller 15 and the process ends.

If the rotational speed of the wheels is equal to or higher than the set value, it is considered that the occupant is sitting on the driver's seat and depressing the accelerator pedal, and is operating the engine at a rotational speed higher than at least at idle. Therefore, it is determined that the occupant having the electronic key 20 is in the vehicle interior, and in step 6, an engine start ID code request signal and a door locking / unlocking ID code request signal are transmitted from the transmitter 2 and the antenna 2a at the ceiling of the vehicle interior.

In step 8, it is checked whether or not the engine start ID code and the door locking / unlocking ID code have been received from the electronic key 20 by the receiver 7 and the antenna 7a installed below the driver's seat. Otherwise, go to step 12. When the engine start ID code and the door lock / unlock ID code are received from the electronic key 20, the engine start ID code and the door lock / unlock ID code received in step 9 are stored and registered in the memory 12b. After that, at step 10, it is confirmed that the ignition switch 9 is off,
If it is turned off, the routine proceeds to step 11, where the engine is stopped and the processing is terminated.

On the other hand, if the engine start ID code and the door lock / unlock ID code have not been received in step 8, the engine start ID code request signal and the door lock / unlock ID code request signal from the timer 12c are received in step 12. Is read, and it is checked in step 13 whether the elapsed time since the transmission of the ID code request signal is within a predetermined time. Step 8 if within a predetermined time
Return to and confirm receipt of the ID code again. If the elapsed time from the transmission of the ID code request signal exceeds the predetermined time, the process proceeds to step 14 and confirms that the ignition switch 9 is turned off. If the ignition switch 9 is turned off, the process proceeds to step 11; Repeat the process. If the ignition switch 9 has been turned off, the engine controller 15 is controlled in step 11 to stop the engine, and the process ends.

If it is determined in step 2 that the ID code is stored in the memory 12b, an engine start permission determination process from step 15 is performed. In step 15, an engine start ID code request signal is transmitted from the transmitter 2 and the antenna 2a installed on the ceiling of the vehicle compartment. Next, at step 16, time measurement is started by the timer 12c. In step 17, it is confirmed whether or not an ID code for starting the engine has been received from the electronic key 20 by the receiver 7 and the antenna 7a installed below the driver's seat.
If received, the process proceeds to step 18; otherwise, the process proceeds to step 21.

When the engine start ID code is received from the electronic key 20, the engine start ID code stored and registered in the memory 12b in step 18 and the engine start ID code sent from the electronic key 20 are entered. If the two match, the process proceeds to step S19. In step 19, an engine start permission signal is transmitted to the engine controller 15 to permit the start of the engine. Here, when the occupant turns the ignition knob 30 to the engine start position (ST), the engine starts. Thereafter, in step 20, it is confirmed that the ignition switch 9 is turned off.
Proceed to 1 to stop the engine by controlling the engine controller 15 and end the process. If it is determined in step 18 that the ID codes do not match, the process ends.

In step 17, the engine start ID
When the code has not been received, the elapsed time from the transmission of the engine start ID code request signal is read from the timer 12c in step 21 and it is confirmed in step 22 whether the elapsed time is within a predetermined time. Step 1 when the elapsed time from the ID code request is within a predetermined time
7, the process waits for reception of the engine start ID code, and when the elapsed time exceeds a predetermined time, the process is terminated.

As described above, according to this embodiment,
When the ID code registration mode is set using the in-vehicle receivers 7, 7a whose communication range with the electronic key 20 is limited to the interior of the vehicle, the in-vehicle receivers 7, 7a use the electronic key 20.
