Abstract
With the background of the higher vocational college students' innovative of 2010 national test plan, This paper introduces an intelligent controlling system of smart car. Which takes the STC89C52 single-chip Microcomputer as the core of control and black and white line sensors as sensing component. At the same time, the light signal is transmited by using sensors and voltage comparator lm393 to detect the black line on the road; meanwhile this detection signal is transmited to microcontroller signal port, with analysising by Microprocessor control . The smart car can travel by black line. This project involves control technology, the sensor technology, computer and power electronics and other professional domain knowledge, make the car can imitate human thought complete scheduled tasks.
