In this study, a new system of an active control hydro-pneumatic suspension for automobile is proposed and its dynamic performance is tested. The proposed system is composed of high speed On/ Off solenoid valves, in stead of a proportional valve or servo-valve in conventional use. As a method for driving the On/Off valves, the pulse width modulation (PWM) method is adopted. Since the choice of On/Off valves driven in digital mode, such as the PWM method, leads the system to an economical and reliable one, it is expected that the proposed system can realize high reliability and cost reduction. The dynamic characteristics of the system are investigated by experiment and digital simulation. These results are compared with those obtained from a conventional system composed of a pressure control valve, and the availability of the proposed system is confirmed.
