An electric power assisted steering system for a vehicle is disclosed. The electric power assisted steering system can include an electric motor configured to apply an assistance torque to a part of a steering assembly so as to assist a driver of a vehicle in turning the steering wheel, a drive circuit for the motor which selectively connects the motor phases to an electrical supply to cause current to flow in the motor phases. The amount of assistance torque applied by the motor can be a function of the current flowing in the phases of the motor. The electric power assisted steering system can include a control circuit which generates a control signal that is applied to the motor drive stage.
