Patent ID: 7843153

Claim:
A control system for controlling an adjustment device which is operated by an electric motor in a motor vehicle, the control system comprising: an indirect anti-trapping system for detecting a trapping situation between an adjustment element, which is moved by the adjustment device in an adjustment movement along an adjustment path, and a vehicle element, wherein the anti-trapping system is configured to stop or reverse the adjustment movement of the adjustment element if a defined threshold value for a mechanical running parameter which results from the adjustment movement is exceeded, an analysis unit for analyzing the adjustment movement of the adjustment element, wherein the analysis unit functions, on the one hand, as a functional component of the anti-trapping system and, on the other hand to check for mechanical functional faults of the adjustment device other than a trapping situation in an analysis mode and to generate a diagnostic message indicating a mechanical functional fault of the adjustment device if a threshold value for a running parameter which is different than the threshold value for the detection of an anti-trapping situation is exceeded.
