Problems solved by technology

With the increase in the number of following vehicles in the fleet, the overall physical length of the fleet is also longer, and the number of historical waypoints that the pilot vehicle needs to send at one time increases, resulting in excessive communication resources being occupied, affecting the overall operating efficiency and driving safety of the fleet

Abstract

The invention provides a way point information transmission method, device and system for an automatic driving motorcade, and relates to the technical field of automatic driving. The method comprisesthe following steps: enabling a way point information transmission device to receive way point information of each period sent by a pilot vehicle-mounted device in real time; storing the way point information of each period to form historical way point information; receiving a way point information transmission control instruction sent by a pilot vehicle-mounted device, and determining target waypoint information from the historical way point information; and sending the target way point information to the first vehicle-mounted device. In the embodiment of the invention, the way point information of the pilot vehicle in each period is independently stored and maintained by the way point information transmission device, and when the following vehicle to be enqueued needs to be enqueued, the way point information transmission device is responsible for determining the target way point information and sending the target way point information to the first vehicle-mounted device of the following vehicle to be enqueued; and the pilot vehicle-mounted device does not need to send a large amount of way point information, so that the communication resource of the pilot vehicle is saved, andthe problem that the communication resource of the pilot vehicle is excessively occupied can be avoided.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular to a method, device and system for transmitting waypoint information of an automatic driving fleet. Background technique [0002] At present, cooperative autonomous driving fleet (Platooning, referred to as autonomous driving fleet) refers to the support of multiple vehicles based on autonomous driving technology and V2V (Vehicle-to-Vehicle, vehicle-to-vehicle) Internet of Vehicles technology. Driving formation status. In formation, the distance between vehicles is far lower than the safe driving distance in the general sense, only 20 meters or less. The extremely small distance between vehicles will cause the airflow broken by the pilot car to be directly caught by the second car at the rear of the car. Acceptance, without forming a low-pressure vortex zone, thereby effectively reducing the total air resistance of the entire fleet during driving. Generally...
