In a steering system for the steered wheels of a vehicle having a steering device such as a steering wheel, a desired wheel angle position transmitter operatively connected to the steering device, a motorized actuating unit for steering the steered vehicle wheels, and a hand force controller operatively connected to the steering device for generating a steering device return force to be felt by a vehicle operator, the energization of the hand force controller is dependent on the sum of a first signal which depends on the actual position of the steering device and the vehicle speed and a second signal which depends on the rate of actuation of the steering device and the vehicle speed.
