Abstract

A suspension control system includes a shock absorber adapted to be mounted between a vehicle body and a wheel axle and having a variable damping force, an actuator operatively connected to the shock absorber and adapted to adjust the damping force developed by the shock absorber, an accelerometer for detecting terrain conditions and outputting a corresponding terrain condition signal, and a controller including a detector for determining terrain conditions in response to the frequency of the terrain condition signal and adapted to control the actuator in response to the terrain conditions as determined. The controller is operable to increase the damping force by a predetermined amount over a predetermined period of time when the accelerometer determines that the terrain includes a bump.
