ABSTRACT:
A suspension control system includes a road surface sensor which produces a road condition indicative signal. A controller detects bounding and rebounding motions of the vehicle suspension on the basis of the road condition indicative signal from the road sensor. The controller monitors when the bounding and rebounding motion exceeds a predetermined level and when its frequency falls within a given frequency range. These conditions reflect typical vehicle body behavior during travel along an undulating road, in which case, the controller produces a control signal to stiffen the suspension system. This suppresses pitching motion of the vehicle on undulating road so as to satisfactorily and successfully provide good riding comfort.
