Preview fuzzy control method for intelligent vehicle path tracking

Abstract

Intelligent vehicle obtains path information by computer vision, and tracks detected path automatically by intelligent control. Through imitating preview driving behavior of human, and integrating driving experience of excellent drivers, an simple and effective preview fuzzy control method for path tracking of intelligent vehicle is presented in this study. The preview fuzzy control method adjusts vehicle speed by preview control according to future path information and adjusts vehicle direction by fuzzy control according to present path information. Simulations and experiments show that intelligent vehicle controlled by the preview fuzzy control method can track various paths accurately, stably and robustly.
