Automotive suspension system and shock absorber therefor

摘要

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 variation rate of the output of the sensor means becomes greater than a predetermined rate and when the output of the sensor means represents a pressure higher than a predetermined level in the piston bounding stroke.
