Embodiment 1

[0036] A vehicle formation method for unmanned driving, comprising the following steps:

[0037] Step 1: After the current team receives the V2X message sent by the application team, the current team judges whether the team length of the application team reaches the team length of the current team. If it does, go to step 5. If not, go to step 2, where the team type Including manned and unmanned fleets, V2X messages include fleet name, fleet origin, fleet destination, fleet length, number of vehicles, fleet speed, fleet distance and fleet position;

[0038] Step 2: The current fleet judges whether the destination of the fleet is the same as that of the application fleet. If they are the same, execute step 3. If not, execute step 5. The fleet contains 2 or more vehicles. All vehicles have the same vehicle speed, vehicle spacing and driving route;

[0039] Step 3: The current fleet combines the map module to determine whether there is an overlapping route between the driving rou...

Embodiment 2

[0051] A vehicle formation system for unmanned driving. Vehicles in the system communicate through the V2X module. The formation between fleets includes the functions of fleet query, fleet merging, fleet splitting and fleet dissolution.

[0052] The vehicle is provided with a control module, a V2X module, a map module and a sensor module, the control module is respectively connected to the V2X module and the map module, and the sensor module is respectively connected to the V2X module and the map module connection, the sensor module is used to obtain behavior data on the vehicle, including vehicle speed, distance between vehicles and vehicle position, the map module obtains the driving route of the vehicle through processing the behavior data on the vehicle, and the control module controls the The V2X module sends commands for the formation function;

[0053] The details of the fleet query function are as follows. The current fleet obtains the entry information of the applying...

Abstract

.The invention belongs to the technical field of unmanned driving, and aims to provide a vehicle formation system and method for unmanned driving. According to the system, vehicles communicate with each other through a V2X module, and the formation of motorcades involves a motorcade query function, a motorcade merging function, a motorcade splitting function and a motorcade disintegration function. The functions are realized by arranging a control module, the V2X module, a map module and a sensor module on each vehicle, specifically, motorcade query and combination instructions are sent by a main control motorcade according to a motorcade length requirement, and the driving parameters of each vehicle in the motorcade are adjusted according to specific joining positions, and therefore, themotorcade is combined with another motorcade to form a new motorcade; the single motorcade is converted into a plurality of new motorcades with smaller motorcade lengths through motorcade splitting; overall regulation, control and planning of traffic on the same route are achieved through combination and splitting of the motorcades; and a vehicle controller can be unmanned driving or manned driving.

Description

technical field [0001] The invention relates to the technical field of unmanned driving, in particular to a vehicle formation system and method for unmanned driving. Background technique [0002] The realization process of the unmanned formation function is as follows: multiple unmanned vehicles form a formation at a specific time and in a specific itinerary to drive in an orderly manner at the same speed and at the same distance, and carry out cargo transportation and passenger loading in specific scenarios. It can be widely used in airports and ports. , large warehouse bases, express transit centers and other locations. The current solution is to use adaptive cruise technology, which is only suitable for the simple traffic environment of a single fleet. With the continuous development of society, there will be more and more unmanned vehicles, and the application of unmanned formations will continue to expand. In the future, unmanned formations will appear on highways and ...
