Title:

ACTIVE SUSPENSION DEVICE FOR VEHICLE

Document Type and Number:

WIPO Patent Application WO/2019/123848

Kind Code:

A1

Abstract:

An active suspension device 2 for a vehicle 1 for controlling, on the basis of the traveling state of the vehicle 1, the damping force of variable-force dampers 12a, 12b, 12c, 12d that are provided between a sprung mass and an unsprung mass for each of multiple wheels 3 of the vehicle 1. The active suspension device 2 comprises: acceleration sensors 15, 16, 17 that detect bobbing at the center of gravity location of the sprung mass of the vehicle 1; and an active suspension control unit 10 that controls the damping force of the multiple variable-force dampers 12a, 12b, 12c, 12d on the basis of the bobbing at the center of gravity location. The damping force of the variable-force dampers 12a, 12b, 12c, 12d is controlled so as to mitigate, from the bobbing in the center of gravity location, vertical movement at the center of gravity location of the vehicle 1.
