Abstract

The electrically powered servo assisted steering system is used in motor vehicles. The electric motor drives the steering shaft on actuation by control system. The assisting force is increased together with an increase of resisting force. The electric motor (18) acts on the steering shaft. The control mechanism incorporates a resistor in the electric motor circuit. This resistor regulates the current supplied to the motor and hence the torque of the motor in relation to the mechanical resistance met on rotating the steering wheel (1).
