Vehicle suspension device for stabilizing steering characteristics
First Claim
1. A vehicle suspension device comprising:
- a shock absorber, disposed between a sprung portion and an unsprung portion of a vehicle, provided for each wheel of the vehicle,plural control sections to which at least two shock absorbers are assigned to be controlled,damping changing means for changing a damping characteristic of each shock absorber assigned to the same control section,detecting means for detecting a difference in a damping force among said shock absorbers,control means for controlling damping characteristics of shock absorbers assigned to the same control section so that a damping characteristic of one of the shock absorbers assigned to the same control section is changed to increase a damping force of the one of the shock absorbers when the difference in the damping force among the shock absorbers assigned to the same control section is increased beyond a predetermined value.

Abstract
A vehicle suspension device includes a shock absorber disposed between a sprung portion and an unsprung portion of a vehicle for each of the vehicle wheels, a damping force changing device for changing a damping characteristic of the shock absorber, a detecting device for detecting a difference in a damping force among the shock absorbers for respective wheels, and a control device for controlling the damping characteristic of the shock absorber so as to restrict the difference in the damping force among the wheels when the vehicle is in a specific running condition. Through the use of such a vehicle suspension device, diagonal vibration can be suppressed, improved running stability can be obtained and riding comfort can be improved.

20. A vehicle suspension device comprising:
-
a shock absorber disposed between a sprung portion and an unsprung portion of a vehicle for each of a plurality of vehicle wheels, plural control sections to which at least two shock absorbers are assigned to be controlled, a damping changing device for independently changing a damping characteristic of the shock absorbers, a detector for detecting a difference in a damping force among the shock absorbers for respective wheels, and a controller for controlling the damping characteristic of the shock absorbers assigned to the same control section so as to restrict the difference in the damping force among the shock absorbers assigned to the same control section when the vehicle is in a specific running condition, the controller controlling the damping changing device so as to increase the damping force of one of the shock absorbers when the difference in the damping force among said shock absorbers assigned to the same control section exceeds a predetermined value. - View Dependent Claims (21, 22, 23)
