PURPOSE:To make it possible to perform optimum frequency responsive independent control, by providing a means for synthesizing variations in load acting upon a cylinder support means and for converting thus synthesized value into a load variation value in a vehicle body input mode so that a desired flow rate is determined in accordance with the variations. CONSTITUTION:Signals from pressure sensors 62 for detecting the internal pressures of cylinders are processed by a high pass filter 64 in a controller unit 60, and thereafter, is delivered into a control circuit 66 in which signals from the pressure sensors 62 are synthesized and are converted into signals in vehicle body input modes such as bound, pitch, roll and warp modes. These converted signals are processed by filters to compute desired mode flow rates. Then, desired flow rates for flow control valves 48 for wheels are determined. With this arrangement, suspension devices 1 for wheels perform optimum independent control in accordance with the frequency in view of the vehicle body input modes. |
