Claim Text:
1. A method of controlling an electric motor of a power steering system having at least three windings comprising: applying a current to the windings of the electric motor by a control unit to generate a total torque having a value which is ascertained by the control unit from a set-point torque for steering assistance and a set-point torque for damping; ascertaining the set-point torque for damping by a damping set-point circuit; ascertaining the set-point torque for steering assistance by a steering assist set-point circuit; monitoring a proper function of the windings of the electric motor by a monitoring circuit; and in the event of a malfunction of any of the windings, outputting an error signal by the monitoring circuit, upon which the set-point torque for steering assistance is reduced.
