Abstract
An apparatus for adjusting a body height of a vehicle by supplying or discharging air into or from an air suspension system includes a controller for controlling a vertical vehicle body height to a predetermined set value responsive to a signal according to an adjustment amount of the vehicle body height obtained by subtracting an objective reference vehicle body height signal from a relative displacement signal. The apparatus further includes vehicle body height change control means connected to the controller for variably controlling a vehicle body height adjustment completion time and a vehicle body height adjusting speed responsive to the vehicle speed. The vehicle body height change control means comprises a sensor for detecting the vehicle speed and generating a signal according to the vehicle speed and a logic circuit for variably controlling the vehicle body height adjusting time and the vehicle body height adjusting speed such that when the vehicle speed signal indicates a high value, the vehicle body height adjusting time is lengthened or the vehicle body height adjusting speed is lowered and when the vehicle speed signal indicates a low value, the vehicle body height adj…
