The path of the college students competition models optimization
Abstract:
    College students competition models optimization design of the system is based on "freescale" cup national smart car competition for college students, light DianTou automatic tracking of driving the car system of mechanical structure, electronic circuit, programming, sensing automatic control scheme, image recognition and optimization design, and get the efficient and stable design scheme as soon as possible.
The intelligent vehicles competition is pided into the photoelectric group, electromagnetic Group and camera group. Path identification module is one of the key modules of the intelligent vehicles, path identification programs directly related to the final performance,so determine the type of path identification module is a key to determining the intelligent vehicles overall program.Detecting the track by photoelectric sensor is non-contact measurement. The measurement circuit have many forms. The subject is designed to collect photoelectric sensor circuit in the national college students’intelligent vehicles competition,and appropriately design some photoelectric sensor circuits, comparison and analysis of the performance of the circuits,make some the optimized programs.The effect s of sensor s’ array , overall arrangement , and space on t he autonomous t race are discussed.
Keywords:    photoelectric sensor；intelligent vehicle；overall arrangement ； comparison of the performance
