PURPOSE:To secure those of responsiveness in steerage, stability and comfortability for driving, etc., according to a driver's choice, by integrally controlling a characteristically variable suspension and a steering gear. CONSTITUTION:A controller 50 makes an input a car speed signal, while the control signal given to a solenoid valve 46 from the controller 50 varies with a car speed. In time of a low speed, the solenoid valve 46 is controlled so as to cause the quantity of pressure oil to be fed to a control valve 31 from a pump 36 to become small in proportion to an increase in the car speed. When a manual switch 54 is set in operation, a level of the signal given to the solenoid valve 46 from the controller 50 drops to some extent whereby the opening of the solenoid valve 46 comes small, and assist force is built up as a whole. Simultaneously, a signal is given to each of solenoids 69 and 74a from the controller 50 so that a characteristic of suspensions for both front and rear wheels comes hard enough. |
