摘要：
Vehicle lateral dynamics aims to study the prediction and control of vehicle active safety. According to the influence of excitative load of road and environment on vehicle lateral dynamics, a vehicle-road-environment coupling model is built, and the limit equation of vehicle risk state is established with concurrent considerations of vehicle dynamic parameters and road and exterior environment parameters. On this basis, according to the distribution function of parameter perturbation under the action of excitative load, the reliability of vehicle dynamic system is solved and Monte Carlo approach is adopted to verify the model. The results show that the model built has good accuracy. Finally, a case study is given to analyze the lateral dynamics response characteristics of vehicle under the action of excitative load of road and environment. © 2019, Society of Automotive Engineers of China.
