A Design of Intelligent Automobile Cruise Control System with Laser Rangefinders

In order to realize the automation of space control of automobile, an intelligent control system was designed, which consists of a laser rangefinders, a speed sensor, a digital controller and a performing motor. The laser rangefinders were developed for the system. The digital controller adopted PIC16F877 SCM, and a step motor was utilized for the performing. Using fuzzy logic theory, an intelligent control scheme was developed to realize the automation of space control according to the error for space and speed in the automobile cruise control system. The method needn't build the accurate mathematic model of object, but according to the artificial experience or state to build the control rule. It avoids the object's uncertainty, noise, infection of nonlinearity and variable time. The experimental results show that anticipative aims are achieved on the prototype machine.
