Abstract
An electric power assisted steering assembly comprises a steering mechanism which operatively connects a steering wheel to the roadwheels of a vehicle, a sensor adapted to produce a first output signal indicative of the torque carried by a portion of the steering mechanism and to produce a second output signal indicative, an electric motor, a signal processing unit having a lead-lag filter to produce an overall torque demand signal, and a motor drive stage adapted to provide a drive current to the motor responsive to the torque demand signal.
