Patent attributes
The present invention provides a control system operable to raise and lower the height of a vehicle based in part on the response characteristics of the vehicle's suspension and vehicle loading. The control system may develop a vehicle suspension system response by mapping a correlation between changes in air pressure of air springs in the vehicle's suspension and a test valve-open-time. During operation, the control system may predict a valve-open-time in response to a command relating to a target air pressure for the air springs, and then inflate or deflate one or more of the air springs for a duration substantially equal to the predicted valve-open-time. This process may be iterated until the control system achieves, within an acceptable degree of error, the target air pressure for the one or more air springs.
