Door lock control apparatus for vehicle
A door lock control apparatus includes a lock switch on an exterior of a vehicle, a controller, and a check device. The controller performs a first key check in response to a lock command inputted through the lock switch. The first key check determines whether an electronic key specific to the vehicle is located outside around the vehicle based on a response from the key. The check device has previously performed a second key check, after the key has been put into a situation in which the key might have been moved from inside to outside the vehicle. The second key check determines whether the key is located inside the vehicle based on the response from the key. The check device stores a result of the second key check as a stored check record, which is then immediately available for checking when the controller responds to an inputted lock command.
