Abstract
A suspension apparatus for vehicles capable of changing a characteristic of suspension by controlling supply/release of fluid into/from hydraulic cylinders which are respectively provided between a vehicle body and each wheel. The apparatus detects vehicle height signals at a plurality of positions and extracts at least a bouncing component signal and a rolling component signal from vehicle-height signals detected by the plurality of vehicle-height sensors. Each of the bouncing component signal and rolling component signals are filtered and are used to control supply/release of fluid into/from hydraulic cylinders based on the filtered signals. A cut-off frequency for the rolling component signal set in said filtering unit is set higher than that for the bouncing component signal.
