Design of Automobile Intelligence Security Control System Based on Microcontroller AT89C51

摘要

AT89C51, being the main control chip, controls the auto speed, brake and clutch while the car is traveling under some situations. A long-distance displacement sensor detected the distance between the sensor itself and the obstacles in front of it, and succeeded in auto controlling the speed (brake and clutch) according to its traveling condition (including speed, maximum acceleration-the roughness of the pavement), which ensured autos to travel at the safe speed.
