By the way, conventionally, as described in Japanese Patent Application Laid-Open No. 2000-85454 , it has been proposed to control the sound of a buzzer for notifying that the light has been forgotten to be turned off when the ignition switch of the vehicle is turned off. When the notification function for forgetting to turn off the light is added to the device as described in the above, when the user approaches the detection area and the user opens the door while the above notification function is operating, the notification function is provided. Since the lamp is lit for a certain period of time, the buzzer sounds for the notification of forgetting to turn off the lamp, which causes a problem that the user feels annoyed.

The present invention prevents the user from feeling annoyed by not giving a notification of forgetting to turn off the lamp when a boarding welcome function such as a notification function is activated by the user approaching a locked vehicle. The purpose is to be able to do it.

In order to achieve the above object, the vehicle control device of the present invention is provided in a vehicle in a vehicle control device for locking and unlocking a door by being locked and unlocked by the user. The door is locked based on either the locking operation of the portable device or the locking operation of the door switch, and the unlocking operation of the portable device and the unlocking operation of the portable device. An actuator that unlocks the door based on any of the unlocking operations of the door switch, and whether or not the portable device is within a predetermined detection area set based on the vehicle is detected, and within the detection area. When the portable device is detected, the vehicle control unit that controls the actuator to lock and unlock the door if there is a pre-locking operation and an unlocking operation, and the detection of the portable device from outside the detection area. The notification control unit that performs notification control assuming that the notification control condition for turning on the predetermined lamp of the vehicle when detected in the area is satisfied, and at least the above-mentioned predetermined state when the power is turned off by the off operation of the ignition switch. When the door is opened while the lamp is lit, the forgotten to turn off notification unit that notifies the forgotten to turn off the lighting as if the forgotten to turn off condition is satisfied, and the forgotten to turn off when the notification control condition is satisfied. The notification unit is provided with a stop request unit that issues an execution stop request for the forget-to-delete notification, and the forget-to-delete notification unit does not perform the forget-to-delete notification if a stop request is issued by the stop request unit. It is characterized by that.

According to such a configuration, when the notification control condition for turning on the predetermined lamp of the vehicle is satisfied by detecting the portable device from outside the detection area to inside the detection area, the stop request unit notifies the forget-to-turn off. If a request to stop the execution of the lighting forgetting notification is issued to the vehicle, the lighting forgetting notification unit does not notify the lighting forgetting to turn off. Therefore, the predetermined lamp lights for a certain period of time when the notification control condition is satisfied. Even if it is, it is possible to prevent the user from feeling annoyed by the notification of forgetting to turn it off.

Further, the stop request unit stops issuing the stop request when a predetermined time has elapsed from the lighting of the predetermined lamp by the notification control unit, and the stop forgetting notification unit stops the stop by the stop request unit. It is preferable to cancel the issuance of the request and perform the forgotten deletion notification when the forgotten deletion notification condition is satisfied.

By doing so, the issuance of the stop request is stopped when a predetermined time has elapsed from the lighting of the lamp due to the fulfillment of the notification control condition, and the forgotten to turn off notification unit satisfies the forgotten to turn off notification condition after the issuance of the stop request is stopped. Since it will be possible to notify that you have forgotten to turn off the lights, when the user tries to get off the vehicle without turning off the lights after a predetermined time has passed since the lamp was turned on due to the condition of the notification control condition, the notification of forgetting to turn off the lights should be sent normally. Can be done.

According to the present invention, when a boarding welcome function such as a notification function based on the establishment of notification control conditions is activated by a user approaching a locked vehicle, there is a request to stop execution of the notification of forgetting to turn off the lights. For example, since the notification of forgetting to turn off the lamp is not performed, it is possible to prevent the user from being annoyed by the notification of forgetting to turn off the lighting even if the predetermined lamp is lit due to the establishment of the notification control condition.
