Embodiment 1

[0054] Such as figure 1 and figure 2 As shown, a method for self-driving vehicles to travel in groups, including:

[0055] S1: Each vehicle in the fleet obtains centimeter-level precision positioning information based on high-precision maps and self-vehicle perception comparison capabilities;

[0056] S2: Each vehicle in the fleet recognizes the model, color, and photo of other cars based on the perception ability of the own car, and obtains the information of other cars within the range of perception of the own car;

[0057] S3: Each vehicle in the fleet uploads its own vehicle's high-precision positioning information, other vehicle information based on visual search, its own vehicle's route planning, control planning information, its own vehicle information, and its own driver's account information to the cloud server;

[0058] S4: The cloud server uniformly formulates the control plan of each vehicle based on the received information of each vehicle in the fleet, and iss...

Embodiment 2

[0071] The difference from the previous embodiment is that in this embodiment, the method further includes that each vehicle of the fleet uploads the high-precision positioning information of the own vehicle to the information layer of the high-precision map of the cloud server, and the cloud server uses This obtains the relative positional relationship between the vehicles of the fleet at the lane level and at the centimeter level. The cloud server uniformly formulates a control plan for each vehicle according to the relative positional relationship among the vehicles of the fleet.

Embodiment 3

[0073] A self-driving vehicle team travel system, including a cloud server, the cloud server cooperates with at least two vehicle controllers to execute the self-driving vehicle team travel method, and the cloud server is used for:

[0074] Receive the high-precision positioning information of the own vehicle uploaded by each vehicle in the fleet, the information of other vehicles based on visual search, the route planning of the own vehicle, the control planning information, the information of the own vehicle, and the account information of the driver of the own vehicle;

[0075] Based on the received information of each vehicle in the fleet, the control plan of each vehicle is uniformly formulated and issued to the corresponding vehicle;

[0076] Send the information of each vehicle in the accepted fleet to other vehicles in the fleet except the own vehicle.

[0077] In this embodiment, preferably, the cloud server is also used to receive the route update request information...

Abstract

The invention discloses a method and system for traveling in a group of autonomous vehicles. The method is based on the information obtained by each vehicle in the group, and the cloud server uniformly formulates the control plan of each vehicle and sends it to each vehicle in the group. According to the control plan, the driving parameters of the self-vehicle are adjusted to complete the group travel function of multiple vehicles with the automatic driving function. The method and system are based on bicycle perception, bicycle positioning, cloud longitudinal distance planning, and bicycle decision-making. Through the coordination among the vehicles in the fleet, the vehicles in the team can be in a similar interval to ensure that each vehicle arrives at a similar time. Destination; ensure that each vehicle follows the same route, avoiding the loss of vehicles in the convoy; realize single-vehicle change of convoy route during driving, avoid misunderstanding in manual communication; realize high-precision positioning information sharing, perception information sharing, Collaboration and sharing of control and command sharing.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and system for traveling in a group of automatic driving vehicles. Background technique [0002] At present, autonomous driving technology has entered the fast lane of rapid development. Some car brands have been able to realize pilot assisted driving (navigation assisted driving) functions on high-speed roads, such as Tesla NOA function, Xiaopeng NGP function, NIO NOP function and GAC Aian NDA function, etc. The automatic driving system of these cars can control the vehicle to enter the high-speed main road through the ramp, complete the overtaking of the low-speed lane, complete the road network switching between expressways, and adjust the speed of the vehicle according to the road speed limit. [0003] Baidu Maps, Gaode Maps, etc. have launched the "teaming" function for multiple people / vehicles to travel together. Drivers can see the location of teammates...
