Problems solved by technology

[0003] After obtaining the positioning information of a certain vehicle, the current position of the vehicle can be determined according to the positioning information of the vehicle. However, because the sizes of different vehicles vary widely, the exact position of the vehicle can be obtained according to the positioning information of the vehicle. Unable to meet the demand for positioning accuracy in high-precision positioning scenarios

Embodiment Construction

[0126] The technical solution in this application will be described below with reference to the accompanying drawings.

[0127] In traditional solutions, the positioning information transmitted between different vehicles or between vehicles and other devices includes the positioning position of the vehicle's positioning unit. Since different vehicle models and vehicle sizes vary widely, the vehicle's positioning units are not necessarily located in the vehicle. on the standard point (for example, the geometric center of the vehicle), therefore, after obtaining the positioning information of the vehicle, the traditional solution generally regards the position of the positioning unit of the vehicle as the position of the vehicle, and it is difficult to Accurately determine the specific location of the vehicle.

[0128] Therefore, in order to obtain more accurate positioning information of the vehicle according to the positioning information in the vehicle network communication, ...

Abstract

The invention provides an Internet of Vehicles communication method, a positioning method and an Internet of Vehicles communication device. The Internet of Vehicles communication method comprises thesteps that the Internet of Vehicles communication device generates positioning information, wherein the positioning information comprises a positioning position of a positioning unit of a first vehicle and an offset distance of the positioning unit relative to a positioning reference point of the first vehicle and the Internet of Vehicles communication device is a device installed on the first vehicle, and the Internet of Vehicles communication device sends the positioning information to other equipment. According to the invention, the current position of the first vehicle can be determined more accurately.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a communication method for the Internet of Vehicles, a positioning method, and a communication device for the Internet of Vehicles. Background technique [0002] In the Internet of Vehicles communication technology, positioning information will be transmitted between different vehicles or between vehicles and other devices (for example, roadside devices) (for example, the positioning information can be carried in the vehicle basic safety message (basic safety message, BSM) Middle), the positioning information generally includes the positioning position of the positioning unit of the vehicle (for example, it may be the longitude and latitude where the positioning unit of the vehicle is currently located). [0003] After obtaining the positioning information of a certain vehicle, the current position of the vehicle can be determined according to the positioning ...
