PURPOSE:To prevent damage of drive circuit parts when a door locking knob is in a locked condition with a key inserted by making a door unlocking signal incapable of unlocking at first and then capable of unlocking after a given time elapses. CONSTITUTION:When a door is closed, together to pull out a key from an ignition switch, with a main door locking knob locked, an unlocking drive signal is outputted, however the signal is uneffective for unlocking, and an automatic locking action is prohibited even in an unlocked condition. An unlocking drive signal for the door locking knob is outputted again after a given time elapses from the unlocking drive signal is outputted. This restrains unnecessary operation times for drive circuit parts, capable of improving durability of drive parts. |
