Design of Intelligent Vehicles Control System based on Photoelectric Detector

Abstract

Given the characteristics of the road information, an intelligent vehicle navigation system based on infrared sensors is developed. Signal collection and processing method are outlined. This paper describes a method cleverly exploiting principles of optics to improve the lane-keeping ability of infrared photoelectric sensors. Considering that the conventional PID can not meet the requirement of motor controls for their real-time character and table lookup based on fuzzy control cannot meet the requirement of steady precision, an improved PID with fuzzy control algorithm is proposed, As a result of test, navigation accuracy is increased by double; dynamic performance and steady precision of the system are both obviously improved by the control algorithm proposed.
