A vehicle system has a steering circuit which includes a steering actuator
supplied with pressurize fluid from a pressure source to turn an
associated vehicle wheel to the left or right in response to the movement
of the steering wheel. A feedback circuit is provided which includes a
steering motor connected with the steering wheel and supplied with
pressurized fluid via an electronically controlled feedback control valve
means in response to signals received from a control unit to generate a
steering feedback force acting on the steering wheel.
