The design of intelligent controller of automobile anti-rear-end based on single chip microcomputer

For ensuring traffic safety requirements and meeting the development of current automobile industry, the paper presents the design against rear-end accident. The design would complete the intelligent control of brake system via using single-chip microcomputer (SCM) data processing ability, and combining the fuzzy control theory. Millimetre wave (MMW) radar is selected to measure the distance between vehicles and the relative velocity of the vehicle in the design. The measurement data would be as the input of the fuzzy controller when it is output after processed in SCM C8051F020. Then the output of the fuzzy controller would be as the parameters to control vehicle brake system, which could effectively prevent the car directly collision accident.
