This paper introduces the design of a simple intelligent vehicle system controlled by SCM AT89S52.The system detects the car using the signal angle sensor and controls the car to do corresponding movement on the seesaw.The board level angle of the angle sensor is zero so as to keep the car in balance,and the induction surface reflection type photoelectric sensor guide line is adopted to keep the car right on the track and guide the car in a specified region to successfully climb up on the board.RT1602 liquid crystal display system is used as system display to show the row spacing,and time.A stepping motor power supply directly powered by 12 V batteries is used as the power source,with a bridge circuit composed of STA475 transistors integrated chip to drive.The MCU ensures the normal operation of the car according to the signals of each module.

Key words: monolithic integrated circuit AT89S52;simple intelligent vehicle system;angle sensor;Step by steps the electrical machinery;RT1602 liquid crystal display
