When the third switch 16c is turned on and the second switch 16b is turned on, a stop signal (hereinafter, referred to as an engine stop code) for stopping the engine is output.

When the third switch 16c is turned off and the first switch 16a is turned on, a lock signal for locking the door (hereinafter referred to as a door lock code) is output. Further, when the third switch 16c is turned off and the second switch 16b is turned on, an unlock signal for unlocking the door (hereinafter, referred to as a door unlock code) is output. (Note that the signals of the various codes described above are stored in the resin case of the grip portion B.
It goes without saying that a circuit unit that generates and outputs the D code and constitutes the transmitter 16 is housed. )

That is, the transmitter (FIG. 6)
Radio signals such as an ID code, an engine start code, an engine stop code, a door lock code, and a door unlock code are received by the receiving antenna 1, and then these radio waves are received. The signal is extracted and detected by the tuner 2. Then, an ID code and various codes (hereinafter, referred to as function codes) are demodulated from the received radio signal and input to the microcomputer 4.

The microcomputer 4 has a parking brake switch 12 turned on, a gear position detection switch 13
Is turned on and the key switch 11 is turned off, and when the engine start code is input, a coil drive signal for starting the engine is sent to the coils of the respective relays 5, 6, and 7. Supply sequentially according to their order. As a result, the respective contacts of the respective relays 5, 6, and 7 are activated and turned on.

The microcomputer 4 starts the engine when an engine stop code is input or when at least one of the above conditions is not satisfied in the parking brake switch 12, the gear position detection switch 13, and the key switch 11. The output of the coil drive signal is stopped, and the engine is not started. Further, when the engine is being driven for the purpose of warm air or the like, the engine is automatically stopped when any one of the above conditions is not satisfied.

Further, the microcomputer 4 turns on the door lock control relay 8 when the door lock code is input, and turns on the door unlock control relay 9 when the unlock code is input.

That is, the microcomputer 4 having the above configuration
Operates according to the flowchart shown in FIG. When power is supplied to the microcomputer 4, the process proceeds from step 10 to step 20, and in step 20, radio signals such as an ID code and a function code (general term for an engine start code, an engine stop code, a door lock code, and a door unlock code) are supplied. Wait for it to be done.

If it is determined in step 20 that any code has been supplied to the microcomputer 4, step 3
The program proceeds to 0, the ID code and the function code are decoded according to the engine start conditions such as whether the parking brake is applied, and the program proceeds to step 40.

In step 40, it is determined whether or not the ID code is the same as the registered ID code. If not, the process returns to step 20. If it is determined that the ID code is the same, the process returns to step 20. Go to step 50, step 5
In step 60, it is determined whether or not the input function code is a door lock code. If it is determined that the input function code is a door lock code, a door lock signal is output to the door lock control relay 8 in step 60. To end the program operation.

If it is determined in step 50 that the supplied function code is not a door lock code, it is determined in step 70 whether or not the supplied function code is a door unlock code. If it is determined that there is, at step 80, a door unlock signal is output to the door unlock control relay 9, and thereafter, the process proceeds to step 130, and the program operation ends.

If it is determined in step 70 that the received function code is not the door unlock code, the process proceeds to step 90. If it is determined that the received function code is the engine start code, a signal for starting the engine is determined in step 100. Is supplied to the engine starter power control relay 5, and then the process proceeds to step 130, where the program operation is terminated.

If it is determined in step 90 that the received function code is not an engine start code, the process proceeds to step 110, where it is determined whether the received function code is an engine stop code. If it is determined that the code is the engine stop code, all relays 5, 6, and 7 are turned off in step 120, and the process proceeds to step 130, after which the program operation ends. If it is determined that it is not the engine stop code,
Thereafter, the routine proceeds to step 130, where the program operation is stopped.

[0016]

However, when an attempt is made to enter a vehicle after starting the engine by remote control using such a device, the engine stop switch is operated after the unlock switch is operated. Otherwise, there is a problem that the vehicle cannot be brought to a state immediately before the start of driving unless the switches are operated in the reverse order.
