Abstract:
A method for electric control and regulation of movement of an electrically operated assembly of a motor vehicle, the assembly having a setting device which is connected to a drive device, and a control and regulating electronics device, the method comprising:restricting at least in a partial area of a displacement path of the electrically operated assembly, a displacement force of the electrically operated assembly to a predetermined boundary value dependent on the displacement path,regulating a first parameter proportional to the displacement force of the electrically operated assembly, upon reaching the predetermined boundary value, to a first parameter value corresponding approximately to the boundary value;monitoring a second parameter correlated with a dynamic of the setting device during a regulating phase;evaluating the second parameter in the control and regulating electronics device;generating a control and regulating action for the drive device; anddelaying at least one of an interruption of current delivered to the drive device and a change of rotary direction of the drive device by a time interval;wherein the time interval is measured so that a satisfactory differentiation can be made between a lammed state and an external temporary dynamic disturbance.
