摘要
PURPOSE: A semi-active suspension system and a control method using the fluid pressure of a hydraulic cylinder are provided to reduce manufacturing costs and to improve ride comfort by mounting an oil pressure sensor on a hydraulic cylinder.;CONSTITUTION: A semi-active suspension system using fluid pressure of a hydraulic cylinder(145) comprises hydraulic sensors(340,350), a suspension control unit(250), and a movable damper(260). The hydraulic sensor is respectively installed in feed tubes(110,117) supplying the working fluid to the left or the right side of pressure chambers(310,320). The suspension control unit compares the pressure of the hydraulic sensors and offers the control commander value by producing an objective decreased force. The variable damper controls the decreased force by an actuator according to the control commander value.;COPYRIGHT KIPO 2010
