The invention provides a vehicle following control method and system for an automatic driving motorcade and a vehicle, and relates to the technical field of automatic driving. In the system, a preceding vehicle-mounted server obtains a preceding vehicle running track of the preceding vehicle-mounted server and extracts track key points according to the preceding vehicle running track; the front vehicle-mounted server sends the track key points to rear vehicle communication equipment through front vehicle communication equipment; the vehicle-mounted server of the rear vehicle performs curve fitting according to the track key points to obtain a historical track curve of the front vehicle; the vehicle-mounted server of the rear vehicle obtains the position and heading information of the vehicle-mounted server of the rear vehicle and performs curve fitting according to any point on the historical track curve of the front vehicle to obtain a motion planning curve; and the vehicle-mounted server of the rear vehicle controls the rear vehicle according to the motion planning curve and the historical track curve of the front vehicle behind the any point, so that the rear vehicle drives according to the motion planning curve and the historical track curve of the front vehicle behind the any point.
Description
Technical field [0001] This application relates to the field of automatic driving technology, and in particular to a follow-up control method, system and vehicle for an automatic driving fleet. Background technique [0002] At present, the collaborative autonomous driving fleet (Platooning) refers to the formation of multiple vehicles based on the support of autonomous driving technology and V2V (Vehicle-to-Vehicle, vehicle-to-vehicle) Internet of Vehicles technology and trailing behind with a very small distance between vehicles. In formations, the distance between vehicles is much lower than the normal safe driving distance, which is only 20 meters or less. The extremely small distance between vehicles will cause the leading vehicle to break through the airflow, and the second vehicle will be directly behind the vehicle. Accept it without forming a low-pressure vortex zone, thereby effectively reducing the total air resistance of the entire fleet during driving. Generally, the...
