Abstract
A method for preventing undesirable lowering of an air suspension system for a motor vehicle includes the steps of sensing vehicle speed of the motor vehicle, determining whether the sensed vehicle speed is equal to a predetermined speed, venting air from the air suspension system to lower a vehicle body of the motor vehicle if the sensed vehicle speed is equal to the predetermined speed, sensing height of corners of the vehicle body, calculating a height rate for the corners of the vehicle body based on the sensed height, determining whether a height rate of a corner of the vehicle body is greater than a predetermined rate, and disabling or halting venting of the air suspension system if the height rate of a corner of the vehicle body is greater than the predetermined rate.
