Study on car intelligent cruise control based on immunity principle

A new car intelligent cruise system was introduced. In the system, the laser range finder, the ultrasonic range finder and the infrared range finder are used for judging dynamic and static state roadblocks around a controlled car and forecasting a possible accident. A self-optimizing fuzzy control with an immune correction coefficient was proposed. It absorbs well the advantages both good off-line optimizing function of fuzzy control parameters in GA and good on-line regulating function with an immune correction coefficient. They were discussed that the fuzzy control parameters optimize on the real-time imitating and the immune correction coefficient real-time regulates based on immune feedback. The system can match the work of an engine and an ATM to ensure the reaction speed, braking effects and security. The application effect is good.
