Abstract
A drive system for a covering device, which can be rolled up or folded, for motor vehicles is equipped with a control device. The control device has a current sensor for detecting the current applied to an electric motor of the drive system in the course of moving the covering device. The control system measures a current parameter at the start of the movement of the covering device and switches off the current to the motor as soon as switch-off criteria derived from the current values measured at the start of the movement have been reached.
