Abstract
In this vehicle height adjustment system, a plurality of actuator assemblies are provided, one corresponding to each one of the vehicle wheels and resiliently suspending it from the vehicle body. These actuator assemblies have pressure chambers, and each is adapted to increase or decrease the vehicle height at a location corresponding to its corresponding wheel as respective results of supplying or discharging of working fluid to or from its pressure chamber. Working fluid supply/discharge means are provided corresponding to the actuator assemblies and supply and discharge working fluid to and from their pressure chambers. Vehicle height detection means are provided for sensing the heights of the vehicle above the wheels. A means detects the rate of change of the steering angle of the vehicle. And a means for computing and control controls the working fluid supply/discharge means, based on the deviations of the actual wheel heights from standard wheel heights, and carries out control adjustment of the actual wheel heights to the standard wheel heights, by performing a prediction calculation of the fluctuations in wheel heights caused by vehicle rolling from the rate of change of st…
