SUSPENSION CONTROL SYSTEM AND SUSPENSION CONTROL METHOD

WIPO Patent Application WO/2024/053432

A1

A suspension control system according to the present invention comprises: a road-surface-distance detection unit (12) which, by means of a distance sensor (11) mounted to a vehicle body, detects a surface distance from the distance sensor to a position on a road surface where a wheel W passes; a mean-road-surface-displacement calculation unit (4) which calculates a mean road surface displacement of a plurality of road surface displacements that are obtained by subtracting a vehicle height from road surface distances at multiple positions corresponding to the length of tire-ground contact length in the rolling direction of the wheel; and an actuator control unit (5) which, on the basis of the mean road surface displacement, controls an active suspension in such a manner as to cause the attitude of the vehicle body to stabilize at a prescribed vehicle height. The suspension control system is configured to perform appropriate preview control according to road surface unevenness.
