Abstract
In an opening control device in a vehicle door, in order to stop the door at a desired position, a control unit stops power supply to a motor, and a short circuit is made in an electric circuit between a first terminal and a second terminal of the motor. In the electric circuit, there is formed a regenerative brake circuit in which regenerative braking can be applied to rotation of the motor. When the door is positioned within a fully-open-position-adjacent range that is adjacent to a fully-open position of the door, regenerative braking is applied to normal rotation of the motor for opening the door and is not applied to reverse rotation of the motor for closing the door.
