ABSTRACT:
A vehicle steering system comprises a power cylinder drivingly connected to front wheels and forming part of a power steering system, and an actuator drivingly connected to rear wheels and forming part of a so-called compliance steer control system. The power cylinder and the actuator are supplied with hydraulic fluid from a pump through first and second control valves which are operated in response to the turning effort applied to a steering wheel. Additionally, a flow dividing valve is provided to distribute the fluid from the pump into the first and second control valves in a predetermined flow dividing ratio, thereby allowing effective independent operations of the power steering system and the compliance steer control system without affecting each other.
