Abstract

The vehicle steering system includes a steering operating device operable by the driver, in particular a hand steering wheel, each one electromechanical actuator for controlling of each steerable wheel of a wheel pair on a steerable vehicle axle at the right and left side of a vehicle body, means which, in the event of failure or a malfunction of one of the two actuators associated with a steerable vehicle axle, ensure the control of the two vehicle wheels of this vehicle axle by the respectively other, still functioning actuator, at least one set-value transducer for a steering angle being adjusted that is operable by the steering operating device, at least one actual-value transducer recording the steering angle of the vehicle wheels, a central control unit which controls the electromechanical actuators in dependence on a comparison of a signal of the actual-value transducer (actual value) with a signal of the set-value transducer (set value), and a data transmission unit which establishes a data communication between the central control unit and the electromechanical actuators.
