ABSTRACT:Intelligent car be automatic operation in the pre-set prospects mode. It is designed by an organic whole of machinery, electronics, detection technology and intelligent control. Intelligent car can be used in the industrial control, it is an important content of the field of Robot research. The toy car is use for the body of Intelligent car in the design. The hardware is made up of the devices of STC89C52RC microcontroller which is the main control chip, dc-motor, photoelectric sensors, LED digital , etc. And it can make the car realize the faction of advances, turn, accelerate, slowing down,etc. It also can accurately finish two cars a starting at the same time, and two cars can run in the same direction in the running lane, realize two car overtaking alternately in overtaking area. The 1602 displays the driving mode of intelligent car. The design shows that this design is simple in structure, reflects intelligent operation in a certain extent and has good robustness.

Key words: Intelligent car; STC89C52RC microcontroller; Infrared sensor; Overtaking alternately
