Abstract
A steering system is provided for controlling the turning angle of the steering wheels of a vehicle. The steering system includes two electro-hydraulic circuits each including an actuator, both actuators being mechanically coupled and acting simultaneously on the turning angle of the wheels. A first circuit is displacement-controlled relative to a position set point while a second circuit is stress controlled. The set point applied of the second circuit includes a component developed from the filtering of the position set point applied to the first circuit.
