Abstract
The suspension device for vehicles includes: an electric damper which operates by electricity; a fluid pressure damper which operates by hydraulic pressure; a road-surface state detector which detects a road-surface state ahead of a tire of a vehicle; and a controller which causes at least one to operate among the electric damper and the fluid pressure damper, based on a detection result of the road-surface state detector.
Claims5
A suspension device for vehicles comprising:
- an electric damper which operates by electricity;
- a fluid pressure damper which operates by hydraulic pressure;
- a road-surface state detector which detects a road-surface state ahead of a tire of a vehicle;
- and
- a controller which determines a propriety of actuation of each of the electric damper and the fluid pressure damper and controls ON/OFF of actuation of each of the electric damper and the fluid pressure damper, based on a detection result of the road-surface state detector,
- wherein
- the road-surface state detector processes detection information of the road-surface state and generates information of a size of a convex part of the road surface as quantitative information of the road-surface state, and
- the controller compares the information of the size of the convex part of the road surface with a predetermined threshold set in advance, and distinguishes whether the size of the convex part of the road surface exceeds the threshold.
