- Abstract:
- To know the features of vehicle steering dynamics and provide theoretical basis for development of vehicle steering control strategy, Lyapunov function of vehicle steering dynamics was built based on the Lyapunov theory of nonlinear motion stability and the model of vehicle steering system. Characteristics of vehicle steering dynamics were studied and the stable area of vehicle steering was gained. To verify the results of the Lyapunov stability, equilibrium point of vehicle nonlinear steering model was solved based on genetic algorithm. The results show that the two results are consistent. Thus, the Lyapunov theoretical method of vehicle steering dynamics can be used to the theoretical research of vehicle steering dynamics.
