Abstract

Disclosed is an ad-hoc network method based on a vehicle-mounted terminal, comprising: a target vehicle-mounted terminal acquiring first physical state information about a target vehicle corresponding to the target vehicle-mounted terminal, wherein the first physical state information at least represents a moving state of the target vehicle and information about a position where the target vehicle is located; and the target vehicle-mounted terminal performing networking in a chain structure mode, at least based on the first physical state information about the target vehicle and taking the target vehicle-mounted terminal as a target node, so that the target node is connected to two adjacent nodes at most. Further disclosed are a vehicle-mounted terminal and a storage medium.

First claim

The invention claimed is:

1. An ad hoc networking method based on an in-vehicle terminal, comprising:
obtaining, by a target in-vehicle terminal, first physical status information of a target vehicle corresponding to the target in-vehicle terminal, wherein the first physical status information is used for indicating at least a moving status of the target vehicle and position information of the target vehicle; and
performing, by the target in-vehicle terminal, an operation related to networking in a chain structure based on at least the first physical status information of the target vehicle by using the target in-vehicle terminal as a target node, to connect the target node to no more than two adjacent nodes,
wherein performing, by the target in-vehicle terminal, the operation related to networking in the chain structure based on at least the first physical status information of the target vehicle by using the target in-vehicle terminal as the target node comprises:
when it is determined that the moving status indicated by the first physical status information does not satisfy a first preset rule, determining, by the target in-vehicle terminal, whether a first broadcast message from an Internet of Vehicles exists; and
when the first broadcast message from the Internet of Vehicles exists, joining, by the target in-vehicle terminal, the Internet of Vehicles in the chain structure according to the first physical status information by using the target in-vehicle terminal as the target node; or
when no first broadcast message from the Internet of Vehicles exists, establishing, by the target in-vehicle terminal, the Internet of Vehicles in the chain structure based on the first physical status information by using the target in-vehicle terminal as the target node, and
wherein joining, by the target in-vehicle terminal, the Internet of Vehicles in the chain structure according to the first physical status information by using the target in-vehicle terminal as the target node comprises:
obtaining, by the target in-vehicle terminal, at least two pieces of second physical status information corresponding to the Internet of Vehicles, wherein the at least two pieces of second physical status information are used for indicating physical status information of at least two first vehicles corresponding to at least two first in-vehicle terminals in the Internet of Vehicles, respectively;
determining a first relative position relationship between the target vehicle and the at least two first vehicles according to the at least two pieces of second physical status information and the first physical status information;
determining, according to the first relative position relationship between the target vehicle and the at least two first vehicles, a target position corresponding to the target in-vehicle terminal in the Internet of Vehicles when the target in-vehicle terminal is acted as the target node, to connect the target node to no more than two target first nodes, wherein the two target first nodes are nodes, in the Internet of Vehicles, corresponding to two target first in-vehicle terminals of the at least two first in-vehicle terminals; and
joining the target node to the Internet of Vehicles according to the target position.

2. The method of claim 1 , wherein connecting the target node to no more than two target first nodes comprises:
when it is determined, according to the first relative position relationship between the target vehicle and the at least two first vehicles, that the target node is a head node or a tail node in the Internet of Vehicles, controlling the target node to be connected to a target first node, so that the Internet of Vehicles to which the target node has been connected has the chain structure; or
when it is determined, according to the first relative position relationship between the target vehicle and the at least two first vehicles, that the target node is neither the head node nor the tail node in the Internet of Vehicles, controlling the target node to be connected to the two target first nodes, so that the Internet of Vehicles to which the target node has been connected has the chain structure.

3. The method of claim 1 , wherein establishing, by the target in-vehicle terminal, the Internet of Vehicles in the chain structure based on the first physical status information by using the target in-vehicle terminal as the target node comprises:
receiving at least two second broadcast messages broadcast by at least two second in-vehicle terminals respectively;
obtaining at least two pieces of third physical status information from the at least two second broadcast messages respectively, the at least two pieces of third physical status information being of at least two second vehicles corresponding to the at least two second in-vehicle terminals respectively;
determining a second relative position relationship between the target vehicle and the at least two second vehicles according to the first physical status information and the at least two pieces of third physical status information; and
establishing the Internet of Vehicles according to the second relative position relationship between the target vehicle and the at least two second vehicles, to connect the target node to no more than two target second nodes, wherein the two target second nodes are nodes, in the Internet of Vehicles, corresponding to two target second in-vehicle terminals of the at least two second in-vehicle terminals.

4. The method of claim 3 , wherein connecting the target node to no more than two target second nodes comprises:
when it is determined, according to the second relative position relationship between the target vehicle and the at least two second vehicles, that the target node is a head node or a tail node in the established Internet of Vehicles, controlling the target node to be connected to a target second node, so that the established Internet of Vehicles has the chain structure; or
when it is determined, according to the second relative position relationship between the target vehicle and the at least two second vehicles, that the target node is neither the head node nor the tail node in the established Internet of Vehicles, controlling the target node to be connected to the two target second nodes, so that the established Internet of Vehicles has the chain structure.

5. The method of claim 1 , further comprising:
obtaining, by the target in-vehicle terminal, fourth physical status information of the target vehicle corresponding to the target in-vehicle terminal; and
when a second moving status of the target vehicle indicated by the fourth physical status information satisfies a second preset rule, removing the target node corresponding to the target in-vehicle terminal from the Internet of Vehicles.

6. The method of claim 1 , further comprising:
obtaining, by the target in-vehicle terminal, fourth physical status information of the target vehicle corresponding to the target in-vehicle terminal; and
when a second moving status of the target vehicle indicated by the fourth physical status information satisfies a second preset rule, removing the target node corresponding to the target in-vehicle terminal from the Internet of Vehicles.

7. An in-vehicle terminal, comprising a processor and a memory storing computer-readable operation instructions, wherein when the computer-readable operation instructions in the memory are run, the processor is configured to:
obtain first physical status information of a target vehicle corresponding to a target in-vehicle terminal, wherein the first physical status information is used for indicating at least a moving status of the target vehicle and position information of the target vehicle; and
perform an operation related to netw
