Problems solved by technology

[0004] However, with the implementation of the existing technology, since there are at least two neighbor lists of the vehicle in the vehicular ad hoc network, each update of the neighbor list maintained by the vehicle can only update one neighbor list. In this way, if a neighbor vehicle updates a If the neighbor list fails, the neighbor vehicle cannot be added to the neighbor list of the vehicle in time, thus weakening the mutual perception between vehicles in the vehicular ad hoc network, thus affecting the performance of the vehicular ad hoc network

Embodiment 1

[0066] The embodiment of the present invention provides a method for establishing a neighbor list, which is applied to the vehicle-mounted equipment on the target vehicle side, such as figure 2 As shown, the method may include:

[0067] S101. Receive state information sent by neighboring vehicles within a preset range, where the state information includes a communication mode adopted by the neighboring vehicles and first information, where the first information is used to characterize the driving state of the neighboring vehicles.

[0068] It should be noted that the target vehicle and the neighbor vehicle in the embodiment of the present invention have a preset range, the vehicles within the preset range centered on the target vehicle are neighbor vehicles, and the preset range centered on the neighbor vehicle Vehicles within range are their target vehicles. That is, there may be multiple target vehicles and neighbor vehicles in the embodiment of the present invention.

Embodiment 2

[0124] The embodiment of the present invention provides a method for establishing a neighbor list, such as Figure 5 As shown, the method may include:

[0125] S301. When the preset time arrives, the neighbor vehicle detects whether it enters a preset coordination area, and the preset coordination area is the area covered by the base station.

[0126] In the embodiment of the present invention, a base station is set at an intersection with relatively congested traffic, and the area covered by the base station is preset as a coordination area.

[0127] It should be noted that the preset coordination area in the embodiment of the present invention refers to geographic location information, for example, location information of an elliptical area centered on an intersection.

[0128] Specifically, when the preset time arrives, the neighbor vehicle can locate its own geographic location information, and compare its own geographic location information with the preset coordination a...

Embodiment 3

[0214] Such as Figure 6 As shown, the embodiment of the present invention provides a neighbor list establishment device 1, corresponding to the establishment method of the neighbor list of the target vehicle, which is set in the vehicle-mounted device, the neighbor list establishment device 1 may include:

[0215] The first receiving unit 10 is configured to receive state information sent by neighboring vehicles within a preset range, the state information includes the communication mode adopted by the neighboring vehicles and first information, the first information is used to characterize the The driving status of neighbor vehicles.

[0216] The updating unit 11 is configured to add the first information received by the first receiving unit 10 into a neighbor list corresponding to the communication mode adopted by the neighboring vehicle.

[0217] optional, such as Figure 7 As shown, the device 1 for establishing the neighbor list further includes: a judging unit 12; whe...

Abstract

The embodiment of the invention discloses a method for establishing a neighbor list. The method comprises the following steps: receiving state information transmitted by a neighbor vehicle within a preset range, wherein the state information includes a communication mode adopted by the neighbor vehicle and first information, and the first information is used for representing a running state of the neighbor vehicle; and adding the first information into a neighbor list corresponding to the communication mode adopted by the neighbor vehicle. Meanwhile, the embodiment of the invention also discloses a device for establishing the neighbor list.

Description

technical field [0001] The invention relates to the Internet of Vehicles technology in the communication field, in particular to a method and device for establishing a neighbor list. Background technique [0002] At present, with the increase in the number of vehicles, the problems caused by vehicles are becoming more and more prominent. For example, highways often have multiple car accidents and serial collisions due to weather reasons, and now there are more and more cars in the city, the traffic is congested, and the driver cannot predict the traffic conditions of the road when driving a car. A wrong driving command will not only delay the driver's time, but also make the congested traffic worse. [0003] In the existing technology, the Internet of Vehicles technology can be used to extract and effectively utilize the operating data of all vehicles, and to effectively supervise the operating status of all vehicles and provide comprehensive services according to different...
