Abstract: This paper presents an off-road tyre model for use in rollover mitigation strategies for a vehicle driven on off-road terrain. A baseline tyre model was first developed through rolling road testing. Off-road tyre testing was then performed on dirt and gravel driving surfaces to develop scaling factors for extending the baseline tyre model to off-road conditions. A yaw and roll stability control algorithm was then developed and implemented in a vehicle simulation environment. The results show that the proposed control algorithm enhances vehicle roll stability and prevents vehicle rollover for the studied emergency manoeuvres on dry asphalt, dirt and gravel.
