In order to improve the precision and security of autonomous parking,a steering kinematics model was establised,taking the initial position and steering-angle as key control factors,and a parking steering control simulation model based on fuzzy algorithm was built with the help of Simulink.Fuzzy rules were established and the autonomous vertical parking was simulated.The influences of initial position,initial angle,and initial speed on vehicle trajectory were analyzed.The simulation shows that changing initial parameters will affect the autonomous vertical parking effect.The minimum initial position for a one-time smoothly parking was determined.The simulation shows that fuzzy control algorithm is sensitive and of no overshoot.
