A new semi-active suspension was developed by the authors et al. The damping force is normally set 'firm' to ensure the high stability and controllability of the vehicle, while it is switched over to a 'soft' instantaneously as soon as some vibration input from the road surface is detected to maintain the desirable ride comfort. The flow force that works on the switching valve is reduced to obtain high functional performance. The solenoid force characteristics is optimized to obtain higher response. The switching noise caused by a sudden change in damping force is reduced by the two-stage taper shape of the valve edge.
