Patent ID: 8810164

Claim:
An opening/closing control device in a vehicle door, comprising: a closing motor switching a door latch in the vehicle door from a half-latch state to a full-latch state; a release motor releasing the door latch with a switch; and a controller that controls the closing motor and the release motor, the controller comprising a switching relay circuit connected to an input current path connected to a vehicle battery, the switching relay circuit switching between a first state where electricity of the vehicle battery is supplied to the closing motor and a second state where electricity is supplied to the release motor, the controller further comprising a closing relay circuit provided between the switching relay circuit and the closing motor to change between an ON state which electricity is supplied to the closing motor and an OFF state where electricity is shut off when the switching relay circuit is in the first state, electricity being supplied to the closing motor by switching the closing relay circuit from the OFF state to the ON state by a half-latch signal from the door latch while the switching relay circuit still remains in the first state, electricity being supplied to the release motor by changing the switching relay circuit from the first state to the second state with the switch.
