Research and Development of Automatic Driving System for Intelligent Vehicles

An innovative universal automatic driving system for intelligent vehicles is designed in this research. With a few mechanical modifications of four subsystems, i.e., steering system, breaking system, throttle system, and gearing system of the original manned vehicles, and the installation of an automatic control device, this system is finally established by connecting each subsystem and upper computer via CAN bus. It is proved by vehicle tests that upper computer can precisely control the underlying subsystem through automatic driving system, and this system can be used not only for vehicle bench test, but also for automatic driving of intelligent vehicles, which establishes a foundation for further researches of unmanned and intelligent control of vehicles.
