Abstract
Ride height for use in an adaptive suspension damping system, tiltable headlamp systems, or other systems is determined for first and second wheels which are mounted to first and second suspensions having first and second control arms coupled between the respective wheels and a frame of the vehicle. An anti-roll system is coupled between the control arms. A mechanical height sensor is coupled to the first wheel to directly sense a first height associated with the first wheel. A strain sensor is coupled to the anti-roll system to generate a strain signal in response to a strain in the anti-roll system. A controller converts the strain signal to a second height associated with the second wheel. Thus, ride heights for both wheels on opposite sides of the vehicle are obtained using only one direct height measurement.
