For a vehicle comprising a body and a plurality of wheels upon which said vehicle runs, a vehicle height adjustment system, comprising: (a) a corresponding plurality of actuator assemblies, each corresponding to one of said vehicle wheels and resiliently suspending said one of said vehicle wheels from the vehicle body, each said actuator assembly comprising a pressure chamber and increasing and decreasing vehicle height at a location corresponding to each said vehicle wheel as a result of supply and discharge of working fluid to and from each said pressure chamber; (b) a corresponding plurality of working fluid supplying and discharging means, each corresponding to one of said actuator assemblies, for supplying and discharging working fluid to and from each said pressure chamber; (c) a corresponding plurality of vehicle height detection means, each corresponding to one of said vehicle wheels, for sensing each parameter representative of the height of the vehicle body over each corresponding one of said vehicle wheels; (d) a means for detecting the rate of change of steering angle of the vehicle; and (e) a computing and control means for controlling said working fluid supplying and discharging means so as to adjust each vehicle height to each standard vehicle height by obtaining each deviation of each actual vehicle height as detected by each said vehicle height detection means from each said standard vehicle height over each said vehicle wheel, performing a prediction calcuation of fluctuations in said vehicle height at each wheel 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 the vehicle speed as detected by said vehicle speed detecting means, and carrying out a correction to the adjustment control of each said working fluid supplying and discharging means based upon each said deviation of each said actual vehicle height from each said standard vehicle height by the calculation results.

For a vehicle comprising a body and a plurality of wheels upon which said vehicle runs, a vehicle height adjustment system, comprising: (a) a corresponding plurality of actuator assemblies, each corresponding to one of said vehicle wheels and resiliently suspending said one of said vehicle wheels from the vehicle body, each said actuator assembly comprising a pressure chamber and increasing and decreasing vehicle height at a location corresponding to each said vehicle wheel as a result of supply and discharge of working fluid to and from each said pressure chamber; (b) a corresponding plurality of working fluid supplying and discharging means, each corresponding to one of said actuator assemblies, for supplying and discharging working fluid to and from each said pressure chamber; (c) a corresponding plurality of vehicle height detection means, each corresponding to one of said vehicle wheels, for sensing each parameter representative of the height of the vehicle body over each corresponding one of said vehicle wheels; (d) a means for detecting the rate of change of steering angle of the vehicle; and (e) a computing and control means for controlling said working fluid supplying and discharging means so as to adjust each vehicle height to each standard vehicle height by obtaining each deviation of each actual vehicle height as detected by each said vehicle height detection means from each said standard vehicle height over each said vehicle wheel, performing a prediction calcuation of fluctuations in said vehicle height at each wheel 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 the vehicle speed as detected by said vehicle speed detecting means, and carrying out a correction to the adjustment control of each said working fluid supplying and discharging means based upon each said deviation of each said actual vehicle height from each said standard vehicle height by the calculation results.
Claim 3
Dependent Claim
48 words
A vehicle height adjustment system according to claim 1, wherein when one of said deviations between one of said actual wheel heights and said corresponding standard wheel height for said vehicle wheel is less than a predetermined value, said computing and control means regards said deviation as zero.
Claim 4
Dependent Claim
39 words
A vehicle height adjustment system according to claim 1, wherein when one of said steering angle rates of change is less than a predetermined value, said computing and control means regards said steering angle rate of change as zero.
