Research And Application Of The Intelligent Automobile Based On Fuzzy-controller

With the development of automotive electronics and intelligent control technology, intelligent vehicle has become the research hotspots in the field of automatic control. Intelligent Vehicle is a complex system integrated with a sense of environment, planning decision and automatic driving. It is a typical high-tech complex with important military and civilian value, which focusing on the use of the automatic control, pattern recognition, sensor technology, automotive electronics, electrical, computer, machinery and many other disciplines. This article describes the design of an automatic tracing smart car based on the chip of FREESCALE MC9S12DG128.The article focuses on the acquisition, processing and recognition of the target path information. The Fuzzy controller using an effective controlling algorithm for intelligent vehicle control makes the smart car track the road fast and accurate. With the CCD camera the system obtains the current road information and deal with the original image, the main useful analysis and information extraction through effective digital image processing algorithms.According to the motion rules of the intelligent vehicle, fuzzy control algorithm and fuzzy PID algorithm can be applied to control the steering and speed of the intelligent vehicle separately. Fuzzy control rules can be generated according to the requirement of the path tracking, which is followed by the generation of the fuzzy control table, then the steering and motion speed of the intelligent vehicle can be regulated after querying the fuzzy control table according to the path information which is already inquired.
