ABSTRACT:
A control device controls an open/close movement of an automotive window pane which is driven by an electric motor. The device comprises a first switch for, when taking ON position, energizing the motor to drive the closure in a first direction toward a pull-opened position and a second switch for, when taking ON position, energizing the motor to drive the closure in a second direction toward a full-closed position. A determining device is provided for determining an energization stopping position which is taken by the closure before taking the full-opened position when moved in the first direction. The energization stopping position and said full-opened position are separated by a given distance. A controller is further provided which stops energization of the motor when the closure comes to the energization stopping position during movement in the first direction. The given distance is a distance for which the closure can run by the force of inertia produced when energization of the motor is stopped upon reaching of the closure to the energization stopping position during movement in the first direction.
