FIG. 1 is a functional block diagram showing the structure of an embodiment. The transmitter 1 and its antenna 1a are incorporated in the ignition key 10 shown in FIG. The ignition key 10 is provided with a door lock switch 10a and a door unlock switch 10b. When the door lock switch 10a is pressed, a preset password and a door lock lock signal are transmitted, and when the door unlock switch 10b is pressed. The personal identification number and the unlocking signal for the door lock are transmitted. In this embodiment, the door lock switch 10a and the door unlock switch 10b are provided separately, but a common switch is provided, and a lock signal and an unlock signal are alternately transmitted each time the common switch is pressed. You may do it.

On the other hand, the vehicle has a receiver 2 and its antenna 2
a is installed, and receives the lock signal or the unlock signal sent from the transmitter 1 and the personal identification number, and outputs them to the control circuit 3. The control circuit 3 is a microcomputer and a memory 3
It is composed of peripheral parts such as a, and executes a control program to be described later to perform registration processing of a personal identification number. Connected to the control circuit 3 are an actuator 4 for locking and unlocking the driver's door lock, a switch 5 for enabling the registration of the personal identification number, and a switch 6 for detecting the locked state of the driver's door. . The memory 3a retains the stored contents even when the vehicle battery is removed or completely discharged.

FIG. 3 is a flow chart showing a registration processing routine executed by the control circuit 3. The personal identification number registration processing of the embodiment will be described with reference to this flowchart. When the switch 5 is turned on in step S11 to enter the registerable state, the registration process is started, and the process proceeds to step S12 to confirm that the driver's seat door is locked by the switch 6. If the door is locked, the process proceeds to step S13, and it is determined whether or not the personal identification number is received from the transmitter 1. At this time, the door lock switch 10a or the door unlock switch 10b of the ignition key 10 is pressed to transmit a lock signal or unlock signal and a personal identification number. In the personal identification number registration processing routine, the lock signal and the unlock signal are transmitted. Ignore the signal and receive only the PIN code. When the personal identification number is received, the process proceeds to step S14, and the received personal identification number is stored and registered in the memory 3a. When the process of registering the personal identification number is completed, the actuator 4 is driven to unlock the driver's seat door in step S15. At this time, the driver's seat door lock knob is driven to the unlocking side in association with the unlocking operation of the actuator 4, and it can be visually confirmed that the registration processing of the personal identification number is completed.

Steps that perform the same processing as the registration processing routine shown in FIG. When the driver's seat door is locked while the personal identification number can be registered, it is determined in step S13 whether or not the first personal identification number has been received. When the first personal identification number is received, the first personal identification number received in step S14 is stored and registered in the memory 3a. In the following step S15, the actuator 4 is driven to unlock the driver's seat door. At this time, the driver's seat door lock knob is driven to the unlocking side in association with the unlocking operation of the actuator 4, and it can be visually confirmed that the registration processing of the personal identification number is completed.

When the driver's door lock knob is driven to the unlocking side to confirm that the registration of the first personal identification number is completed, and subsequently it is desired to register the second or more personal identification number, The driver's door lock knob is manually operated by the passenger to the lock side. In step S16, it is determined whether or not the driver's door is locked by the switch 6, and if locked, it is determined that there is a request for registration of two or more personal identification numbers, and the process returns to step S13 to confirm the first personal identification number. If the driver's seat door remains unlocked for a predetermined time after registration, the PIN number registration process ends. When registering the second or more personal identification numbers, it is determined in step S13 whether or not the second or more personal identification numbers are received from the transmitter 1, and if received, stored in the memory 3a in step S14. And register. Then, in step S15, the actuator 4 is unlocked by the actuator 4. As a result, it is possible to visually confirm that the driver's seat door lock knob is again driven to the unlocking side, and the second or more personal identification numbers are registered.

In the above-described embodiment, the example in which the door lock knob is driven to the unlocking side by the actuator to visually confirm the completion of the registration of the personal identification number is shown, but the registration confirmation method of the personal identification number is limited to the above-mentioned embodiments.
