Abstract

See full text

A vibration control apparatus for vehicles to be installed on the vehicle wherein a vehicle body is supported on a truck through springs and damping mechanisms, for suppressing the vibrations of the vehicle body and enhancing the riding quality of the vehicle, comprising a vibration detector which detects the vibration of the vehicle body, a compensator circuit which compensates the detection output of the vibration detector and produces a control output for suppressing the vibration of the vehicle body, a fluid operating mechanism which controls the relative displacement between the vehicle body and the truck and which is connected to the vehicle body on one side and to the truck on the other side, a fluid control device which controls the fluid operating mechanism by the use of the control output produced by the compensator circuit, and damping control means to suppress the damping function of the damping mechanism upon sensing the state under which the vibration of the vehicle body is suppressed by the fluid operating mechanism.
