For a vehicle comprising a body and a plurality of wheels upon which said vehicle runs, a vehicle height adjustment system, comprising: (a) a plurality of actuator assemblies, one provided corresponding to each one of said vehicle wheels and resiliently suspending said one of said vehicle wheels from the vehicle body, said actuator assemblies comprising pressure chambers and each increasing and decreasing vehicle height at a location corresponding to its corresponding vehicle wheel as respective results of supply of working fluid to and discharge of working fluid from its said pressure chamber; (b) a plurality of working fluid supplying and discharging means, which arc providcd corresponding to said actuator asscmblics, for supplying working fluid to said prcssurc chambers and for discharging working fluid from said pressure chambcrs; (c) a plurality of vehicle height detection means, which arc provided corresponding to said vehicle wheels, for sensing parameters representative of the heights of the vchiclc body over said vehicle wheels; (d) a means for detecting the rate of change of the steering angle of the vehicle; and: (e) a computing and control means for controlling said working fluid supplying and discharging means based on the deviations of the actual wheel heights as detected by said vehicle height detection means from standard wheel heights, and carrying out control adjustment of said actual wheel heights to said standard wheel heights, by performing a prediction calculation of the fluctuations in wheel heights caused by vehicle rolling from the rate of change of steering angle as detected by said means for detecting said rate of change of steering angle and from the vehicle speed as detected by said vehicle speed detecting means, and by carrying out a correction to the adjustment control of said working fluid supplying and discharging means, based upon the calculation result, by an amount appropriate substantially to eliminate said wheel height fluctuations.

Claim 3
Dependent Claim
40 words
A vehicle height adjustment system according to claim 1, wherein said computing and control means is for, when the deviations between the actual wheel heights and the standard wheel heights are less than certain values, regarding said deviations as zero.
Claim 4
Dependent Claim
39 words
A vehicle height adjustment system according to claim 1, wherein said computing and control means is for, when said steering angle rate of change is less than a certain value, regarding said steering angle rate of change as zero.
