PURPOSE:To improve controllability, by a method wherein, in a control device for a suspension device with car body orientation regulating function, from signals for a car speed sensor, a steering angle sensor, a brake sensor, and an accelerator sensor, a change in orientation is predicted, and a change in oil quantity to offset a change in prediction is synthesized at each wheel for control. CONSTITUTION:A control circuit 7 predicts a change in a roll amount with time from a signals from a car speed sensor 8 and a steering angle sensor 9, a change in a forward inclination amount with time from signals from the car speed sensor 8 and a brake sensor 10, and a change in a backward inclina tion amount with time from signals from the car speed sensor 8 and an accelera tor sensor 11. In order to offset the changes with each other, a change in a quantity of oil fed and discharged to and from a hydraulic cylinder 2 is deter mined, and from the result, a synthesizing change amount of each wheel is computed. By means of the synthesizing change amount of each wheel, oil feed and discharge means 4a-4d are controlled. This constitution enables execu tion of control at a real time and improvement of controllability. |
