Abstract
A vehicle height adjust control apparatus that increases the durability or service life of a fluid system, including a fluid supply-discharge device and a fluid actuator, can have a pressure sensor and vehicle height sensors. If a microcomputer determines that the pressure detected by the pressure sensor is greater than a predetermined pressure, the microcomputer changes a target vehicle height to a vehicle height presently detected by the vehicle height sensors. In a preferred construction, the target vehicle height is changed to the vehicle height presently detected, if it is determined that the detected pressure remains greater than the predetermined pressure for at least a predetermined length of time. The predetermined length of time is changed to a longer time when the fluid temperature is relatively low. These additional determination conditions prevent unnecessary or ineffective changes of the target vehicle height due to by a sensor abnormality or a fluid temperature change.
