Abstract:

In this paper, a steering forecasting model of four-wheel-driving electric vehicle is established based on the expanded EIman network, and a nonlinear adaptive forecasting controller of the network is put forward by means of system identification. Moreover, by feeding back the distribution proportion of longitudinal force, the control method of vehicle stability with the aid of driving force distribution between axles is investigated. Simulated and analytical results indicate that the proposed method with good predictive control ability achieves smooth control and rapid target tracking, so that it effectively improves the lateral dynamic stability of vehicles, and helps the driver to modify the steering characteristics of the vehicles in most conditions.

Key words: driving force distribution, stability control, Elman network
