Suspension control system for automotive vehicle with adjustment of wheel slippage dependent wheel load distribution
First Claim
1. A suspension control system comprising:
- a suspension system disposed betweena vehicle body and a suspension member pivotably mounted on a vehicle body and rotatably supporting a road wheel;
first means, associated with said suspension system, for adjusting suspension characteristics for adjusting load exerted on said road wheel;
second means, for monitoring preselected suspension control parameter for providing a first parameter data;
third means for monitoring state of traction at said road wheel for producing a second parameter data; and
fourth means, receiving said first and second parameter data, for controlling operation of said first means, said fourth means being active in a first mode while said second parameter data is greater than or equal to a predetermined threshold level, for controlling operation of said first means on the basis of said first parameter data, and a second mode while said second parameter data is smaller than said predetermined threshold level, for controlling operation of said first means so as to increase traction so that said second parameter data becomes greater than or equal to said predetermined threshold level.

Abstract
A suspension control system includes a mechanism for monitoring wheel slippage on each of individual wheels as a parameter represenatative of road/tire traction. Suspension control is performed generally according to the vehicle driving conditions reflected in various suspension control parameters, such as vehicular speed, lateral acceleration and so forth in order to adjust spring coefficient or damping characteristics of a suspension system which is provided between a vehicle body and a suspension member supporting each individual wheel in order to adjust wheel load distribution and whereby to minimize variation of vehicular attitude change. Suspension control is further performed with taking the road/tire friction as one of suspension control parameters in order to provide traction dependent wheel load distribution.
