<p>PURPOSE: To provide an automatic lock releasing device concurrently on an automatic lock device in a low cost, by attaching a circuit for lock releasing and a discriminating circuit to the existing structure of an automatic lock device. CONSTITUTION: Inside the door of a car body, an actuator 32 for lock releasing to drive a ratch in the direction to release the engagement with a striker is provided. And by a control circuit 43 for lock releasing of a door lock control unit 40, the power feeding to the actuator 32 for lock releasing is controlled. And a discriminating circuit 42 connected to a terminal 40g in which a full ratch switch 13 and a handle switch 15 are connected in parallel is provided to the control unit 40. In the discriminating circuit 42, the power feeding control to the control circuit 43 for lock releasing is carried out by deciding that it is a door opening time, when a signal indicating the switching operation from the terminal 40g is input for the time longer than a specific short time. And the power feeding control is prohibited in the cases other than the above condition.</p> |
