Abstract
A variable damping force shock absorber control system for an automotive vehicle is provided. This control system includes a variable damping force shock absorber adapted to have a plurality of damping modes of operation each assuming different damping characteristics, a vertical acceleration sensor for detecting vertical acceleration acting on a vehicle body, and a control unit. The control unit mathematically determines vertical speed of the vehicle body based on the vertical acceleration to select one of the damping modes based on the vertical speed, and determines the amount of damping force in each damping mode according to a vibratory condition indicative parameter which is varied as a function of a variation in amplitude of the vertical acceleration.
