Control strategy to improve the ride of a North American pick up truck
- View All
This paper deals with the problem of ride and one feasible control strategy solution. Ride in this study is understood as the comfort of the passengers in forward travel in a cruise speed and exposed to road disturbances. This problem is usually addressed with appropriate damping calibration; however for different speeds and road conditions, even a well tuned suspension has limitations. The possibility of semi active solutions is therefore considered and a control strategy with heuristic properties is proposed for heave, pitch and roll motion in a separate fashion. It is the intention of this study to formulate laws separately that can be implemented for future integration. Copyright © 2009 SAE International.
