ABSTRACT:
A control system for an electromechanical drive in a vehicle has a motor (29) whose connections (24, 25) are connected to the assigned control elements (2, 3) of a bridge circuit, a control circuit (21) with signal connections (12, 13) at which control signals are provided for controlling the control elements, a return circuit (6) through which information about the operating state of the motor (29) is returned to the control circuit (21) in order to monitor the functioning of the motor, wherein the signal connections (12, 13) can be switched as output or as input, the information about the operating state is returned through the return circuit (6) to these signal connections that can be switched as input or as output, and the control circuit has a monitoring program (21) that records and evaluates the returned information about the operating state during a monitoring phase in which the signal connections (12, 13) are switched as input.
