As more and more researchers begin to analyse the dynamics characteristics of high-degree-of-freedom and nonlinear vehicle models, it is very important and valuable to propose a new analysis method for this type of model. Moreover, it is a promising research direction to propose quantitative indicators for analysing global vehicle dynamics. Therefore, on the basis of classic works, this paper proposes and verifies a quantitative analysis method — dissipation of energy method for 5-DOF nonlinear vehicle plane motion model for the first time. The quantitative indicators for vehicle nonlinear dynamics is expanded. The transfer relationship between the energy components is revealed, which shows that the dissipation of energy method can reflect the dynamics characteristics and stable region characteristics of the nonlinear 5-DOF vehicle system. The effects of tire force lateral-longitudinal coupling and driving modes on global dynamics are analysed. Finally, the prospect of this method is discussed.
