| Abstract: | A vehicle following system and the corresponding vehicle dynamics model were set up to verify the feasibility of applying sliding mode control in vehicle following system with stochastic disturbances. A controller for the system was designed by sliding mode control method. The stability of the control system was studied by applying vector Lyapunov function method, and the sufficient conditions for exponential mean-square stability of the system were obtained. The stochastic disturbance involved in simulation was the resistances to vehicles. Simulation results showed that in less than 5 s, the accelerations and the speeds of the following vehicles converge to that of the leading vehicle, and the vehicle spacing errors approched to less than 0.05 m. |
