Modeling and analysis on effect of driving force for vehicle stability

This paper presents an extend definition between tyre friction and longitudinal slip rate. The extend definition can be used for modeling 5-DOF planar motion nonlinear dynamics vehicle system with driving force. The phase portraits of the 5-DOF model are obtained by numerical computation. With the compare among different phase portraits, the primary analysis of distinct driving mode and driving force have been achieved, especially under the combined slip driving condition.
