Patent ID: 7923947

Claim:
Electromotive power steering for a motor vehicle, having an electronic control device for commutation of the winding phases of the electric motor, the electric motor being a reluctance motor in which each of the coils of the winding phases encloses a plurality of stator teeth, and the winding phases are, during operation of the motor, in contact with a current source wherein in each instance central pole formation toward the rotor occurs, and that, for the purpose of detecting an error event in the electronic control device and/or in the reluctance motor the information of the signals from a torque sensor provided on the steering column being simultaneously used, such information being conducted for evaluation to the control unit of the electronic control device and, in the event of an error event is separated from the current source by means of short-circuiting of the current source downstream from a safety device by means of a thyristor.
