RESEARCH ON VARIABLE STRUCTURE FUZZYCONTROL IN THE AUTOMATED HIGHWAY SYSTEM

摘要

After introducing the conception and the characteristics of the Vehicle Lane Keeping System(VLKS) in Automated Highway System(AHS), a double structure fuzzy controller isdesigned in this paper, which guides the vehicle (jeep) to run within the given lane based onthe collected information from the magnetic markers on the road surface. A double structurefuzzy control system is described in detail, one structure designed for the straight road and theother designed for the curve road. The membership function and controller variables are setaccording to the driver's experience and experiment. The result of simulation and experimentproves that the fuzzy controller is effective.
