Riding comfort and safety are the two important factors of a personal vehicle. Combing the electronic and hydraulic regulating units to satisfy the requirements of people becomes the important object of the researchers. A quarter-car in this study is designed and built for investigating the dynamic models of semi-active and active suspension systems and their control performance. The adjustable shock absorber with six different levels is designed and applied for semi-active suspension system; besides, an active shock absorber of a new structure, which integrated the hydraulic actuator and a shock absorber, is also designed and applied. The experimental results are also undertaken for the comfort level, the power spectral densities (PSD) of the sprung mass acceleration are shown. In additional, both of the concepts of Active and Damping Control (ADC) and Intelligent Comfort Control are also proposed for the future car.
