Verifications of Movable Roll Center Behaviors in Vehicle Body Frame Geometry

Abstract This paper proposes a novel geometrical vehicle model which can verify behaviors of the roll center in vehicle body frame geometry. In this approach, a kinematic roll center can be numerically defined on the basis of the coordinates of vehicle body frame, which are measured and converted by suspension stroke sensors. The proposed geometrical model has been verified by a series of experiments using a test passenger vehicle, especially paying attention to the dynamic roll center behaviors during slalom operations.
