  • Vehicle steering system of the by-wire design type
    Patent number: 8162095
    Abstract: A vehicle by-wire steering system includes a hydraulic default level. A hydraulic feed unit and a hydraulic actuating unit can be connected together by two hydraulic lines such that when an actuator is non-functional, a steering wheel rotational angle is transformed into a corresponding wheel steering angle by the hydraulic feed unit and the hydraulic actuating unit. The hydraulic lines can be connected together by a switchable steering valve, which is designed as a proportional servo valve, of which the flow cross section can be adjusted in essence continuously between the two extremes of completely closed and completely open.
