Embodiment 1

[0048] The vehicle positioning method provided in this embodiment, such as figure 1 shown, including the following steps:

[0049] Step 100: set up a VANET, and the vehicle is used as an OBU in the VANET network;

[0050] Here, the specific process of establishing the VANET can adopt the existing technology.

[0051] like figure 2 As shown, the nodes of the established VANET include: multiple OBUs and multiple Road Side Units (RSU, Road Side Unit); wherein, most of the nodes of the established VANET are OBUs, and the RSUs are generally set on fixed devices on the side of the road.

[0052] In the established VANET, the communication between nodes is divided into the communication between OBU and OBU and the communication between OBU and RSU; among them, the communication between OBU and OBU can also be called V2V communication; the communication between OBU and RSU The communication of the vehicle can be referred to as the communication between the vehicle and the RSU (V2R...

Embodiment 2

[0090] to achieve figure 1 As shown in the method, this embodiment also provides a vehicle positioning device, such as image 3 As shown, the device includes: a communication module 31 and a first determination module 32; wherein,

[0091] A communication module 31, configured to perform V2V communication;

[0092] The first determination module 32 is configured to determine the geographic location of the first OBU in the VANET where it is located by means of V2V communication.

[0093] Wherein, the first determination module 32 may include: an acquisition module, a distance ratio determination module and a position determination module; wherein,

[0094] An acquisition module, configured to acquire geographic location information of the second OBU in the VANET and the third OBU in the VANET; wherein, the second OBU and the third OBU are two OBUs adjacent to the first OBU before and after;

[0095] The distance ratio determination module is used for the transmission duratio...

Abstract

The present invention discloses a vehicle positioning method. The method comprises the steps that a vehicle ad hoc network VANET is established, and the first on board unit OBU in the VANET determines the geographical position of the unit through the mode of vehicle to vehicle V2V communication. The invention also discloses a vehicle positioning device.

Description

technical field [0001] The invention relates to the technical field of vehicle positioning, in particular to a vehicle positioning method and device. Background technique [0002] At present, a global positioning system (GPS, Global Positioning System) or a combination of GPS and an inertial navigation system is generally used to realize vehicle positioning. [0003] However, when the GPS and inertial navigation system are not installed or the installed GPS and inertial navigation system fail, the vehicle cannot know its own position. In addition, when the GPS signal of the vehicle is blocked, the inertial navigation system cannot maintain accurate positioning for a long time, which will cause a large deviation in the positioning of the vehicle, and may even fail to locate. Contents of the invention [0004] In order to solve the existing technical problems, the embodiments of the present invention provide a vehicle positioning method and device. [0005] An embodiment o...
