The hydraulic active vibration isolation technique attracts much attention recent years. In 1991, TOYOTA developed an active hydro-pneumatic suspension system for the SOARER car, which was composed of the pressure proportional valve and the hyaro-pneumatic cylinder. Comparing with the conventional passive suspensions, this system can provide a better ride comfort and handling.

计算机控制的液压主动隔振系统是国外近年来研究和应用较多的一种隔振系统。90年代初，日本丰田汽车公司在其部分高级轿车上安装了一种由压力比例阀和油气缸组成的液压主动悬架系统，与传统的被动悬架相比，该系统能更有效地隔绝路面不规则对车体的扰动和减小转弯、刹车等情况下车体姿势的变化。
