Abstract
An automotive suspension system employs a pressure sensor means designed for monitoring fluid pressure in a fluid chamber of shock absorber to be compressed during piston bounding stroke. Variable suspension characteristics to vary suspension mode between HARD mode and SOFT mode so that suspension mode is normally set in SOFT mode and switched into HARD mode when the peak value of variation rate of the output of the sensor means is detected. The suspension system is provided a deadband for maintaining the suspension mode unchanged even when the peak of variation rate is detected.
