Abstract: A lock release control device for an opening and closing body configured to control an opening and closing body that opens and closes an opening portion of a vehicle. The opening and closing body comes into contact with a sealing member provided on a vehicle body side of the vehicle in a fully closed state. The vehicle includes a locking device and an opening and closing actuator. The locking device restrains the opening and closing body in a fully closed position. The opening and closing actuator displaces the opening and closing body by rotation of a motor to change the opening and closing body from one of two states including an open state and a closed state to another of the states. The lock release control device is configured to execute an open command acquisition process, a pull-in process, and a lock release process.

Abstract: An opening/closing body control device for vehicles that comprises a lock device and a control device. The control device comprises: a reverse control unit that executes reverse control that rotates a rotating member in reverse, after closing control has been completed; and a position detection unit that detects the rotation position of the rotating member, on the basis of the on/off state of a neutral switch. The position detection unit is capable of detecting whether the rotation position of the rotating member is in a closed area, a release area, or a neutral area. The reverse control unit does not execute reverse control if the rotation position of the rotating member is in the neutral area, when the closing control has been completed.

Abstract: A device for controlling an opening/closing body for a vehicle provided with a locking device and a control device, the control device being provided with an inverse rotation stopping unit for stopping the inverse rotation of a rotary member based on the on/off state change of a first neutral switch or the on/off state change of a second neutral switch, and a re-inversion control unit. The re-inversion control unit executes re-inversion control for causing the rotary member to rotate in a first direction when the inverse rotation of the rotary member is stopped based on the on/off state change of the second neutral switch in inversion control after close control, and not causing the rotary member to rotate in a second direction when the inverse rotation of the rotary member is stopped based on the on/off state change of the second neutral switch in inversion control after release control.
