ABSTRACT

In the early 21st century, with the development of automotive electronic technology and intelligent technology, automatic driving is becoming more and more popular. Intelligent car control uses sensor technology, embedded technology, automatic control technology and so on. In this paper, it will introduce the background of intelligent car firstly. After that, the hardware design of intelligent car is displayed, in which the key parts include the motor drive module to realize the function of forward, backward and steering through optocoupler and H-bridge, the infrared line patrol module reads the black and white lines on the road through five infrared sensors to realize the function of automatic line patrol, the infrared navigation module reads the infrared from the beacon through four infrared sensors to realize the function of beacon search. Finally, an intelligent car with the functions of line patrol, automatic parking, distance measurement and navigation is designed.
