Abstract
A vehicle height control system is provided. This height control system is directed to establish fluid communication between right and left suspension actuators or between front and rear suspension actuators, balancing fluid pressures in the actuators for leveling a vehicle body when height level difference between right and left wheels or between front and rear wheels is greater than a first threshold value within a given period of time after an ignition switch is turned off. The height control system then blocks the fluid communication when the height level difference lower than a second threshold value smaller than the first threshold value is maintained for a preselected period of time for preventing the fluid communication between the actuators from being blocked, and instantaneously terminating the height control when the height level difference becomes smaller than the second threshold value due to variation in vehicle load caused by passengers getting in or out of a vehicle and/or baggage loaded into or unloaded from a baggage compartment.
