Abstract
An active suspension system for an automotive vehicle is provided which regulates relative displacement between a vehicle body and wheels. This suspension system includes first and second gain controllers associated with hydraulic cylinders for supressing vehicular rolling based on lateral acceleration acting on the vehicle body. The first and second gain controllers amplify the level of the lateral acceleration, monitored by a sensor, by first and second gains respectively to vary pressure of the hydraulic cylinders. The suspension system further includes a low-pass filter which restricts a frequency of a signal output from the acceleration sensor high than a preselected cutoff frequency to decrease the second gain relative to the first gain to reduce the degree of load shift for the rear wheels relative to that of the front wheels.
