摘　要：利用紅外對(duì)管檢測(cè)黑線與障礙物，并以STC89C52單片機(jī)為控制芯片控制電動(dòng)小汽車的速度及轉(zhuǎn)向，從而實(shí)現(xiàn)自動(dòng)循跡避障的功能。其中小車驅(qū)動(dòng)由L298N驅(qū)動(dòng)電路完成，速度由單片機(jī)輸出的PWM波控制。

Intelligent tracking and obstacle-avoid car

Abstract：Based infrared detection of black lines and the road obstacles, and use a STC89C52 MCU as the controlling core for the speed and direction, A electronic drived, which can automatic track and avoid the obstacle, was designed and fabricated. In which, the car is drived by the L298N circuit, its speed is controlled by the output PWM signal from the STC89C52.
