Abstract
A suspension control system includes: a vehicle speed sensor for providing a signal representing a vehicle speed, a vehicle body behavior variation detecting device for detecting variations in behavior of a vehicle body, and a vehicle speed deciding device for calculating a vehicle speed from the signal provided by the vehicle speed sensor to compare the vehicle speed with a predetermined vehicle speed. The control system further includes a vehicle body behavior variation counter for counting vehicle body behavior variations for a predetermined period of time according to an output of the vehicle body behavior variation detecting device, a damping force changing device for changing a vehicle body suspension damping force at least in three steps and a damping force determining device for determining a damping force according to the vehicle speed decided by the vehicle speed deciding device and the number of vehicle body behavior variations counted by the vehicle body behavior variation counter, to apply an instruction signal to the damping force changing device, so that, when the vehicle speed decided by the vehicle speed deciding device is equal to or higher than a first predetermined vehicle speed, and when the number of vehicle body behavior variations counted by the vehicle body behavior variation counter is equal to or higher than a first predetermined value, the damping force changing device operates to increase the damping force to an increased value and to maintain the damping force at the increased value.
