ABSTRACT:
A control apparatus which detects vertical and/or lateral vibrations of a vehicle body and controls, on the basis of amplitude and frequency of vibration, a characteristic of a support unit for supporting the vehicle body, such as, a damping force and a spring force of suspension or torsion quantity of a stabilizer. The control apparatus, when the detected vibration is high frequency vibration, obtains the frequency of vibration by a measured value of one cycle period, and, when the detected vibration is low frequency vibration, obtains the frequency of vibration by a measured value of a half cycle period.
