That is, before the door switch 1A as the door opening / closing detection means 1 detects that the door is in the closed state, the door lock switch 7A as the door lock detection means 7 detects that the door is in the locked state. Then,
It is configured to determine that the door is locked when getting off the vehicle.

This corresponds to the lock mode when the door is locked without using the key when getting off the vehicle. The door is locked by operating the lock knob of the door, and then the outer handle is pulled while closing the door. Therefore, when the door is locked, the second control means 5 described later can stop the light-off delay state.

As a result, the door lock detecting means 4 at the time of getting off the vehicle
The operation of the second control means 5 is as follows according to the flowchart of FIG. That is,
Since the door lock switch 7A is on, step S
1, the on-route is taken, and the door switch 1A is used this time (immediately after time t5) and the previous time (immediately before time t5).
Since it is in the off state, the off route is taken in step S2, the on route is taken in step S3, and the process goes to step S4.

In step S4, the state of the door key lock switch 6A is determined, but the door key lock switch 6A is in the off state, and the step S5 is performed through the off route.
Is executed. Then, the keyless lock signal indicates time t5.
In step S5, the on state is instantaneously turned on, the on route is taken in step S5, and the room lamp is turned off in step S6.

In this manner, the room lamp 3 is immediately extinguished in the mode in which the door is locked when the user disembarks by using the remote unit (keyless entry) without using a key. In this mode, the door lock is confirmed by extinguishing the door. It will be. On the other hand, if it does not correspond to the above three modes, the door is not locked when getting off, so that step S7 is executed through the off route in step S1, the on route in step S2, the off route in steps S3, S4, and S5. , First
Under the control of the control means 2, a normal delayed turn-off operation is performed.
