Abstract

The invention relates to a steering system which is used to control the steering angle of steered wheels (13, 14) of a vehicle, comprising means (2) of determining the angular position of the steering wheel (1) and two hydraulic or electro-hydraulic systems (6, 5) which are each used to control an actuator (11, 12) that acts on the steering angle of the wheels (13, 14) according to the angular position of the steering wheel (1). The invention is characterised in that it also comprises means which are used in normal mode to operate the two hydraulic or electro-hydraulic systems (5, 6) simultaneously and means of temporarily de-activating one or other of said two hydraulic or electro-hydraulic systems as desired, particularly when the vehicle is moving.
