The following describes a vehicle positioning method, device, communication equipment and readable storage medium provided by embodiments of the present invention.

Referring to Figure 1, Figure 1 is a schematic flowchart of a vehicle positioning method provided by an embodiment of the present invention. The vehicle positioning method shown in Figure 1 can be executed by the vehicle. Specifically, it can be executed by the vehicle terminal in the vehicle. The vehicle terminal is used to calculate the high-precision positioning of the terminal through the received satellite positioning signal and high-precision positioning service information. Accurate location information, and report real-time high-precision location information to the vehicle-road collaboration platform. The vehicle-mounted terminal can communicate with roadside equipment through the PC5 interface, and can also communicate with the cellular communication network through the Uu interface.

As shown in Figure 1, the vehicle positioning method may include the following steps:

Step 101: Obtain the service account and the current location information of the vehicle.

In this embodiment, the service account is used to log in and use the positioning platform. Preferably, the positioning platform is a high-precision positioning platform. The high-precision positioning platform determines the positioning accuracy of the vehicle according to different levels of the service account. The service account is allocated through the vehicle-road collaboration platform. After receiving the service account, the vehicle terminal logs in to the high-precision positioning platform according to the service account and uses it. In the current existing technology, multiple positioning platforms cannot be uniformly associated. Therefore, the vehicle-road collaboration platform and multiple positioning platforms can be unified managed through service accounts. For example, different positioning platforms can be used through different service accounts. . Specifically, the account information of the service account is included in the high-precision positioning service account list, which includes the high-precision positioning service account, password, accuracy level and usage status, as shown in Table 1. Table 1 shows the high-precision positioning service account number. The list can allocate service accounts to vehicles with different needs, thus achieving flexible allocation.

It is used to compensate for the measurement error of satellite positioning signals and improve the positioning accuracy of the terminal. After the positioning is completed, the vehicle-mounted terminal can no longer use the vehicle-road collaborative application, or the vehicle-road collaborative application to be used is changed and the changed vehicle-road collaborative application does not require high-precision positioning, or the vehicle-mounted terminal enters a state that does not require high-precision positioning. Within the service area, the terminal no longer needs high-precision location services at this time; changes in the application can be reported by the terminal to the vehicle-road collaboration platform, or the vehicle-road collaboration platform detects that the vehicle has not been detected within a time threshold. Use high-precision location-related applications. When the terminal no longer needs to use the high-precision positioning service account, the account management module of the vehicle-road collaboration platform takes back the account and sets the usage status of the account to idle in the high-precision positioning service account list; because the vehicle-mounted terminal has obtained the account The password of the account. In order to ensure that the account is not stolen, the account management module can initiate a password change to the high-precision positioning platform.

Vehicle-road collaborative applications that use high-precision positioning do not require high-precision positioning at all locations. They may only be required in some important areas, such as highway ramp merging safety warnings. High-precision locations are only needed near ramp intersections. Then the vehicle-road collaboration platform can set the range of 1km (this distance is just an example) near the ramp intersection as an area that requires high-precision location information. When the rough location reported by the vehicle-mounted terminal enters this area , only vehicle-mounted terminals need high-precision positioning, otherwise high-precision positioning services are temporarily not needed on other ordinary road sections.
