1. automatic pilot system for road vehicle, comprise:

  • the vehicle '"'"' trunk information control station of setting sends to the on-vehicle information receiving processor with the gps satellite of highway pavement and vehicle or GLOCE-A satellite positioning navigation information and local traffic information, the on-vehicle information receiving processor sends automatic driver behavior instruction to the vehicle self-actuated controller, by the automatic operation realization Vehicular automatic driving of vehicle self-actuated controller;

    Comprise;

    1), is set with vehicle '"'"' trunk information control station, can receive on gps satellite or GLOCE-A satellite positioning navigation information and the vehicle '"'"' highway pavement lane geo-localisation information that embeds the constant mark thing at interval constantly continuously, send the travel traffic information on the local road surface of highway of place to vehicle continuously constantly after treatment;

    information such as the vehicle location before and after comprising before and after the track, vehicle place on the track, the left and right sides in the certain limit distance in the certain limit distance, car speed;

    2), embed the constant mark thing at interval on the lane on the highway pavement, marker can send this point of sign, can be the vehicle '"'"' trunk information control station of having set and receive the wired or wireless locating information of handling or can send the visible light identification information simultaneously;

    3), the information automatic reception treating apparatus that is equipped with on the vehicle, can receive and handle the road surface and the vehicle condition information at the vehicle place that vehicle '"'"' trunk information control station sends by vehicle-mounted self-driving computer constantly;

    4) in the vehicle-mounted self-driving computer that, is equipped with on the vehicle Vehicular automatic driving program software is installed, confirm to correct automatically the Vehicle Speed directional ray of driving vehicle position point and the deviation that the vehicle traveling information directional ray is produced constantly, the travel speed directional ray and the vehicle traveling information directional ray of driving vehicle position point are consistent, vehicle-mounted self-driving computer through automatically handle confirm the back to vehicle control device send speed change, change, automatic steering instructions such as bend and braking preparation;

    5), when highway pavement is bend, the travel speed directional ray of driving vehicle position point and vehicle traveling information directional ray are handled through vehicle-mounted self-driving computer, make track, vehicle heading information be modified to circular arc automatically, vehicle-mounted self-driving computer sends the automatic steering instructions of bend to vehicle control device after handling affirmation automatically, the travel speed directional ray of driving vehicle position point and vehicle traveling information directional ray are consistent;

    6), when the travel speed directional ray of driving vehicle position point and vehicle traveling information deviation that directional ray produces surpass the safe range of Vehicular automatic driving program software identification, vehicle-mounted self-driving computer sends the Brake stop operational order from the trend vehicle control device.
