This paper presents an analysis of vehicle trajectory on curved path, in the presence of lateral sliding. The pure rolling motion is not always possible especially where working conditions are rough and not predictable. To take sliding effects into account, the variables which characterize sliding effects are introduced into the mathematical model (steering angle, vehicle speed, tire cornering stiffness and etc.). This mathematical model is linear with two freedom degrees. From the study based on the verification of force in the contact zone tire/ground, we conclude that speed exceeding 60 km/h and small steering angles can destabilize the vehicle.
