Abstract:
A closure apparatus for a vehicle door including a striker disposed on one of a periphery of a door and a periphery of an opening to be closed with the door, and a lock apparatus disposed on the other of the periphery of the door and the periphery of the opening, wherein a driven member of one of the striker and the lock apparatus is forcibly operated with a motive force of a drive motor to bring the door from an incomplete door-close condition to a complete door-close condition, wherein the closure apparatus comprises a main actuation member, a stopper member, a position detector, and a controller, whereinthe main actuation member is movable, relative to a waiting position for the main actuation member to wait for operation of the driven member, on one side to an actuation position for the main actuation member to actuate the driven member and on another side to a detection position for the main actuation member to be detected, with the waiting position therebetween, the stopper member is configured to limit movement of the main actuation member toward the other side, when the main actuation member is moved to the detection position by rotation of the drive motor in one of forward and reverse directions and brought into contact with the stopper member, the position detector comprises an electrical value detector configured to detect movement of the main actuation member to the detection position in dependence on a change in an electrical value of the drive motor at a time when the main actuation member comes into contact with the stopper member, and the controller comprises a motor controller configured to effect a rotation of the drive motor in the other of the forward and reverse directions when the main actuation member is moved to the detection position, and to stop the rotation of the drive motor when the electrical value of the drive motor has a value within an allowable range or when a prescribed amount of Time has elapsed, to return the main actuation member from the detection position to the waiting position.
