摘要：

On the basis of the analysis of vehicle longitudinal dynamic control system, the control problem of longitudinal automatic tracking based on two vehicles is discussed. The second order model of two-car following motion is established and the logic switching rule of acceleration/braking is designed. The three parameters of PID are adjusted by parameter self-tuning fuzzy PID control to control the variation range of the error between the vertical relative distance and vertical relative velocity of the controlled vehicle and the navigating vehicle to achieve the purpose of longitudinal control of the vehicle. The sufficient conditions for the stability of fuzzy PID control system are obtained by using the small gain theorem. The simulation results show that this method can reduce the overshoot of the system compared with the general fuzzy control, and enhance the dynamic anti-jamming ability. It has certain robustness and can solve the contradiction between the fastness and small overshoot. © 2017 Institute of Thermomechanics CAS, v.v.i.
