Side Wind Compensation using Active Suspension

Abstract
This thesis investigates what mechanisms that contribute to the interaction between lateral and vertical dynamics in a fourwheeled vehicle. For this a vehicle model was derived. To capture all the essential dynamics of the vehicle, both a horizontal model and a vertical model was used. The interaction between the models turned out to be quite evident, making it possible to use the active suspension system to influence the yaw dynamics of the vehicle. Further, it was investigated how this effect could be used for attenuating the effects of wind gusts. Since steer by wire is still a topic of active research and it's integration into vehicles lies in the future, this cannot presently be used for side wind rejection. With the vehicle model, it...
