Abstract

An adjustment device for a closure element on a vehicle, such as e.g. a window pane, a sunroof or a convertible top, is provided. The closure element is adjustable between an open and a closed position by means of the adjustment device, wherein the adjustment device includes a drive motor and an electronic control unit for adjusting the closure element and the control unit comprises a bridge circuit, in order to supply the drive motor with electric power and control the rotational speed and the direction of rotation of a drive element of the drive motor to be coupled with the closure element. The bridge circuit is connected with at least one additional load of the vehicle, such as e.g. a window heater, and is formed and provided to control the energization of the at least one additional electronic load.
