Claim Text:
1. A ride height control system for a vehicle having air suspension including front and rear corner airbags in all four corners of the vehicle, the system comprising, a velocity monitor, ride height sensors, a processor receiving height inputs from the ride height sensors and velocity inputs from the velocity monitor, and a cross-flow averager cooperating between the front airbags and in communication with the processor wherein said front and rear corner airbags include at least one selectively inflatable and selectively deflatable airbag for mounting in each corner of the four corners of the vehicle and wherein the four corners of the vehicle are the front corners including the front left and front right corners and the rear corners including the rear left and rear right corners, and wherein said ride height sensors are mounted one in each corner of the four corners of the vehicle, and wherein said cross-flow averager and said processor cooperate with at least said ride height sensors corresponding to at least the front corners so as to provide a single pseudo height controller controlling airflow between said corresponding front corner air bags, by selective actuation of said cross-flow averager, wherein said velocity monitor monitors velocity of the vehicle and provides velocity information to said processor, and wherein said processor is adapted to cause said cross-flow averager to prevent a cross-flow of the airflow between said front air bags in both of said front corners when said velocity is above a non-zero pre-set forward velocity and to allow a cross-flow of said airflow between said airbags in both of said front corners when said velocity is below said pre-set forward velocity, whereby selective actuation of said cross-flow averager enables control of the height of the front left and front right airbags either individually, or collectively by means of said single pseudo height controller.
