Abstract
A controller is operative to: receive vehicle body accelerations from a vehicle; use the body accelerations to calculate heave, pitch and roll (HPR) dynamic signals based on the received body accelerations; select frequency ranges based on the HPR dynamic signals (and/or other vehicle dynamic signals) to be controlled; calculate a combined control strategy based on the selected frequency ranges; and adjust a damper of the vehicle based on the control strategy.
