Description

Technical Field

[0001] The present invention relates to a method and system for transmitting and displaying real-time vehicle data information to a terminal, belonging to the technical field of intelligent decision making. Background Art

[0002] As traffic volume and people's purchasing power increase, the number of vehicles on the lanes also increases. At the same time, people have higher and higher requirements for the real-time reception and display of data by vehicles. For example, in a traffic jam scenario, the traffic jam information ahead needs to be transmitted to the vehicle terminal in real time so that the driver can make timely decisions on the traffic scenario. The time it takes for traffic information and vehicle information from other places to be transmitted to the vehicle terminal system determines the real-time nature of the data between vehicles.

[0003] At present, there are many ways to transmit data between the system end for detecting traffic data and the vehicle terminal. For example, V2X communication technology can realize the key technology of communication between vehicles and the surrounding environment, including communication between vehicles (V2V), vehicles and roads (V2I), vehicles and people (V2P), and vehicles and networks (V2N). Through V2X communication, vehicles can obtain real-time data such as driving information, road conditions, and traffic signals of surrounding vehicles, thereby realizing more intelligent driving assistance and safety warning. When transmitting data between vehicles, the existing technology first detects data and passes the detected data to the relay vehicle, which is then forwarded to other vehicles by the relay vehicle. There is a problem in this process. When the detected data is not the data requested by the relay vehicle, if the relay vehicle stores and forwards the data, some unnecessary vehicles will be involved in the data transmission process. Secondly, the existing technology usually pre-analyzes the transmission delay under a certain communication mode, and then applies the communication mode with small transmission delay to the actual scene. However, the actual scene is complex and changeable, and it cannot be guaranteed that the optimal communication mode under the test scene is still the optimal communication mode in the actual scene. In serious cases, the real-time transmission of data will also be greatly reduced. Therefore, a solution is urgently needed to reduce unnecessary vehicle involvement and improve the real-time performance of data transmission. Summary of the invention

[0083] S2. According to the data acquisition request, the vehicle end is divided into regions to obtain the divided regions of the vehicle end; based on the data acquisition request, the vehicle end within the divided regions is classified to obtain classified vehicles; and an intermediary vehicle between the data acquisition end and the vehicle end and a target vehicle of the intermediary vehicle are selected from the classified vehicles.

[0084] The embodiment of the present invention divides the vehicle end into regions according to the data acquisition request, so as to divide the vehicles belonging to the communication range of the data acquisition end into vehicles in the same region based on the communication range of the data acquisition end.

[0085] Among them, the divided area refers to the area connected by the vehicle positions within the communication range of the same data acquisition terminal. For example, if the communication range of the same data acquisition terminal is area A, and the vehicle positions in area A are 1, 2, and 3, then the triangular area formed by 1, 2, and 3 is used as the divided area.

[0086] In one embodiment of the present invention, the vehicle end is divided into regions according to the data acquisition request to obtain the divided regions of the vehicle end, including: querying the vehicle position of the vehicle end from the data acquisition request; obtaining the transmission position of the data acquisition end; dividing the region of the data acquisition end based on the transmission range of the data acquisition end and the transmission position to obtain a first divided region; determining whether the vehicle position belongs to the same first divided region; when the vehicle position belongs to the same first divided region, generating a second divided region of the vehicle position, and using the second divided region as the divided region of the vehicle end.

[0089] In one embodiment of the present invention, based on the data acquisition request, the vehicle terminals in the divided area are classified to obtain classified vehicles, including: querying the request content of the vehicle terminals in the divided area from the data acquisition request; calculating the content similarity between each request content in the request content; performing initial vehicle classification on the vehicle terminals in the divided area according to the content similarity to obtain initially classified vehicles; querying the vehicle position, vehicle speed and transmission range of the initially classified vehicles from the data acquisition request; and calculating the number of neighboring vehicles of the initially classified vehicle according to the vehicle speed and the transmission range using the following formula:

[0092] Based on the number of neighboring vehicles, the first neighboring vehicle of the initially classified vehicle is queried using the vehicle position; it is determined whether the initially classified vehicle exists among the second neighboring vehicles of the first neighboring vehicle; when the initially classified vehicle exists among the second neighboring vehicles of the first neighboring vehicle, the initially classified vehicle and the first neighboring vehicle are clustered to obtain classified vehicles.

[0094] Optionally, the process of determining whether the initially classified vehicle exists among the second neighboring vehicles of the first neighboring vehicle is as follows: first, the number of neighboring vehicles of the first neighboring vehicle is calculated; then, based on the number of neighboring vehicles and the vehicle positions, the second neighboring vehicles of the first neighboring vehicle are queried; and finally, the i-th initially classified vehicle is queried among the second neighboring vehicles.

[0095] Furthermore, an embodiment of the present invention selects an intermediary vehicle and a target vehicle of the intermediary vehicle between the data acquisition end and the vehicle end from the classified vehicles, so as to select the vehicle that can transmit data in the shortest time based on the length of time it takes for the data acquisition segment to transmit data to the vehicle end and for the vehicle end to distribute the received data to other vehicle ends, thereby extracting the real-time performance of data transmission in the subsequent process.

[0096] The intermediary vehicle refers to a vehicle that receives data sent from the data acquisition end, and the target vehicle refers to a vehicle that receives data forwarded by the intermediary vehicle.

[0104] The number of simultaneous distributions refers to the number of vehicles to which the intermediate vehicle simultaneously distributes the received data. For example, if the number of vehicle terminals belonging to the same category in the classified vehicle is 5, one of them temporarily acts as an intermediate vehicle, and The target vehicle for the intermediary vehicle can be distributed simultaneously in 3 vehicles, which means that under one-way propagation delay, the intermediary vehicle can send data to three vehicles at the same time, and also needs to receive the response information of these three vehicles (consuming one one-way propagation delay), and finally consumes another one-way propagation delay to distribute data to the fourth vehicle.
