Abstract
A control device in a suspension having a link rod includes a pair of fluid-sealed bushings provided on the respective opposite ends of the link rod and having hydraulically adjustable compliances, a valve mechanism for varying the compliances of the fluid-sealed bushings, an actuator for actuating the valve mechanism, and a control mechanism for controlling the actuator. The control mechanism includes a first sensor for detecting the acceleration of vertical vibrations of the vehicle body and generating a signal commensurate with the detected acceleration, a bandpass filter connected to the first sensor for transmitting a signal having a frequency range in the vicinity of the natural frequency of the sprung mass of the vehicle, a second sensor for detecting the steering angle of the steering wheel and generating a signal commensurate with the detected steering angle, a third sensor for detecting when the vehicle is braked and generating a signal when the vehicle is braking, and a circuit for processing the signals from the bandpass filter, the second sensor, and the third sensor to control the actuator based on the processed signals. The control device can control the compliances of the bushings dependent on the road conditions and the conditions in which the vehicle is operated.
