ABSTRACT:
A suspension control system having a suspension unit between a wheel and a body of a vehicle, a fluid supply device for supplying a fluid to the suspension unit, a fluid discharge device for discharging the fluid from the suspension unit, an amplitude measurement device for measuring the amplitude of vertical vibrations of the vehicle body, a threshold value setting device for setting a threshold value of the amplitude of vertical vibrations, a controller for cancelling expansion and contraction of the suspension unit by controlling the fluid supply and the fluid devices when the amplitude of vertical vibrations is equal to or larger than the threshold value, a counter for counting the number of times the fluid supply and fluid discharge devices are controlled by the controller in a predetermined time period, and a threshold value changing device for setting, when the number of times counted by the counter is equal to or larger than a reference number, the threshold value in the threshold value setting device to a value equal to or smaller than an upper limit but larger than a value to which the threshold value was set at a preceding time, and for setting the threshold value to a value equal to or larger than a lower limit but smaller than the value at the preceding time, when the counted number of times is smaller than the reference number.
