Abstract

See full text

An apparatus for controlling damping coefficients for respective vehicular shock absorbers is disclosed in which a plurality of shock absorbers are interposed between predetermined parts of a vehicle body and tire wheel and are provided with damping coefficient changing members, each changing member varying the coefficients of the damping shock absorbers at multiple stages by changing position of an associated actuator, the actuator receiving a signal to change the position of the damping coefficient changing member on the basis of an input signal derived from a sprung mass vertical G sensor. Particularly, a correction portion is provided in a control unit which varies a position change rate of the damping coefficient changing member according to a value of the input signal derived from an input signal sensor, e.g., the sprung mass vertical G sensor.
