[0006] The current process of the base station-based cellular positioning network system is as follows: the terminal reports measurement information; the base station calculates based on the terminal-reported information and the base station measurement information; the positioning result is returned to the terminal. Although the base station-based cellular positioning system has the advantages of wide coverage without the need for a new positioning system , but there are the following problems: it needs the assistance of a positioning network composed of base stations, and the time delay is large, and the positioning accuracy is low

Embodiment 1
[0093] 1. RSU1 and RSU2 obtain their location information from the network;
[0094] 2. RSU1 and RSU2 determine the wireless resources they use according to the resource selection method, and broadcast their own positioning information on them;
[0095] 3. The V2X vehicle terminal 1 enters the indoor area;
[0096] 4. The upper layer application of the V2X vehicle terminal 1 determines that positioning is required;
[0097] 5. The V2X vehicle-mounted terminal 1 searches for surrounding V2X terminal information;
[0098] 6. The V2X vehicle-mounted terminal 1 recognizes the positioning information broadcast by RSU1 and RSU2, and uses them as candidate positioning references. And finally determine to select the two as the positioning benchmark;
[0099] 7. The V2X vehicle terminal 1 communicates wirelessly with RSU1 and RSU2, and other positioning methods based on wireless signals can be used here;
[0100] 8. The V2X vehicle terminal 1 performs its own positioning based on t...

Abstract
The invention relates to a vehicle positioning method and device, and a terminal device. The method includes the following steps: obtaining positioning information sent by a peripheral device after apositioning instruction is received; selecting the peripheral device that meets a preset condition as a positioning reference according to the positioning information; and obtaining the positioning information of a location of a vehicle according to a wirelesssignal relationship between the vehicle and the peripheral device as the positioning reference. With the help of a plurality of fixed equipment having a V2X capacity (referring to Vehicle-to-Everything, information exchange between a vehicle and the outside) deployed in a parking stall of an indoor parking lot or near a lane in a vehiclenetwork, information interaction is directly performed on the terminal device having the V2X capacity through V2V, and indoor accurate location information of the vehicle is obtained without deploying a positioning network; and compared with traditional indoor positioning methods, network bandwidth overhead and computation overhead are reduced, and the complexity and cost of the positioning network are reduced.
Description
technical field [0001] The present invention relates to the field of parking lotvehicle positioning, in particular to a vehicle positioning method, device and terminal equipment. Background technique [0002] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position monitoring of people and objects in the indoor space. [0003] Commonly used indoor positioning technologies mainly include GPS positioning (Global Positioning System, Global Positioning System), Bluetooth positioning, infrared positioning, WSN positioning (ie Wireless Sensor Network, wireless sensor network) and RFID positioning (Radio Frequency Identification, radio frequency identification), UWB positioning, ultrasonic positioning and cellular base station positioning, etc. ...
