An electric power assisted steering apparatus comprises a steering mechanism which operatively connects a steering wheel to the road wheels of a vehicle, an electric motor operatively connected to the steering mechanism, a torque signal generator adapted to produce a torque signal, a column angular position signal generator for producing a column angle signal and a signal processing unit adapted to receive the column torque signal and the column angle signal and to produce therefrom a torque demand signal representative of a torque to be applied to the steering mechanism. A torque demand signal generating circuit adapted to produce the torque demand signal is a function of both the friction compensating torque and the assistance torque signal, at least partially assists the driver in overcoming the effects of static and/or kinetic friction.
