PURPOSE: To unify all of door locks of automobile door lock devices in the same state.

CONSTITUTION: Locking/unlocking states of a plurality of locks are stored in a locking/unlocking memory 1. A locking/unlocking judging means 2 judges whether one of the plurality of locks is changed from locking to unlocking or from unlocking to locking. Locking/unlocking signals generated by the locking/unlocking judging means 2 are then emitted from a locking/unlocking output means 4 for locking or unlocking. The outputted signals are then stored in an outputted signal memory 5. Then judging is made to determine whether the state of storage in the locking/unlocking memory 1 and the state of storage in the outputted signal memory 5 are agreed with each other or not. When disagreement is found after starting of an actuator, the judgement is made that operation for locking/unlocking is executed newly. Then, the actuator is made to restart to work along the state stored in the locking/unlocking memory 1. Therefore, durability of the actuator can be improved while keeping all of the door lockings under a unified state.
