以下对本发明实施例提供的一种车辆定位方法、装置、通信设备及可读存储介质进行说明。The following describes a vehicle positioning method, device, communication equipment and readable storage medium provided by embodiments of the present invention.

参见图1,图1是本发明实施例提供的车辆定位方法的流程示意图。图1 所示的车辆定位方法可以由车辆执行,具体地,可以由车辆中的车辆终端进行执行,车辆终端用于通过接收到的卫星定位信号和高精定位服务的信息,计算出终端的高精度位置信息,并将实时高精度位置信息上报到车路协同平台,车载终端可与路侧设备之间通过PC5接口进行通信,也可与蜂窝通信网之间通过Uu接口进行通信。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.

如图1所示,车辆定位方法可以包括以下步骤:As shown in Figure 1, the vehicle positioning method may include the following steps:

步骤101、获取服务账号和车辆的当前位置信息。Step 101: Obtain the service account and the current location information of the vehicle.

在本实施例中,服务账号用于登陆并使用定位平台,优选的,定位平台为高精度定位平台,高精度定位平台根据服务账号的不同等级确定车辆的定位精度。服务账号通过车路协同平台进行分配,车辆终端接收到服务账号后根据服务账号登陆高精度定位平台并进行使用。在目前现有技术中,无法将多个定位平台进行统一关联,因此通过服务账号可以实现将车路协同平台与多个定位平台进行统一管理,示例性的,可以通过不同服务账号使用不同定位平台。具体地,服务账号的账号信息包括在高精度定位服务账号列表中,其中包含了高精度定位服务账号、密码、精度级别及其使用状态,如表1所示,表1位高精度定位服务账号的列表,可以为不同需要的车辆分配服务账号,从而实现了灵活分配。车辆的当前位置信息由车辆终端进行获取,需要注意的是,该当前位置信息为车辆的粗略位置,高精度定位平台通过该粗略位置及其他信息可以对车辆实现高精度定位。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. The current position information of the vehicle is obtained by the vehicle terminal. It should be noted that the current position information is the rough position of the vehicle. The high-precision positioning platform can achieve high-precision positioning of the vehicle through the rough position and other information.

表1Table 1

步骤102、在基于所述服务账号成功登陆定位平台的情况下,向所述定位平台发送所述车辆的当前位置信息。Step 102: When the positioning platform is successfully logged in based on the service account, send the current location information of the vehicle to the positioning platform.

在本实施例中,车辆终端获取到车路协同平台分配的服务账号及服务账号对应的密码后,在高精度定位平台进行登陆,当登陆成功后,车载终端周期性将当前的粗略位置发送至高精度定位平台。In this embodiment, after the vehicle terminal obtains the service account assigned by the vehicle-road collaboration platform and the password corresponding to the service account, it logs in to the high-precision positioning platform. When the login is successful, the vehicle terminal periodically sends the current rough position to the high-precision positioning platform. Precision positioning platform.

步骤103、接收所述定位平台基于所述当前位置信息生成的差分定位信息和卫星生成的卫星定位信号。Step 103: Receive differential positioning information generated by the positioning platform based on the current position information and satellite positioning signals generated by satellites.

在本实施例中,定位平台接收到车载终端发送的粗略位置后进行计算处理,并向车载终端周期性的播发对应的差分定位信息。卫星定位信号通过卫星对地方定位生成,为常规的卫星定位信号。In this embodiment, the positioning platform performs calculation processing after receiving the rough position sent by the vehicle-mounted terminal, and periodically broadcasts the corresponding differential positioning information to the vehicle-mounted terminal. Satellite positioning signals are generated by satellites for local positioning and are conventional satellite positioning signals.

步骤104、根据所述差分定位信息和卫星定位信号生成定位信息。Step 104: Generate positioning information based on the differential positioning information and satellite positioning signals.

在本实施例中,定位信息为车辆的高精度位置,具体地,车载终端根据接收到的卫星定位信号和差分定位信息计算车辆终端的高精度位置;其中,车载终端根据接收到的差分定位信息用于补偿卫星定位信号的测量误差,提高终端的定位精度。在定位完成后,车载终端可以不再使用车路协同应用,或变换了要使用的车路协同应用且该变换的车路协同应用中无需高精度位置,或车载终端进入到不需要高精度定位服务的区域范围内,此时终端不再需要高精度位置服务;使用应用上的变化可以是由终端报给车路协同平台的,也可以是车路协同平台在一个时间阈值内检测到车辆未使用高精度位置相关的应用。当终端不再需要使用高精度定位服务账号后,车路协同平台的账号管理模块收回该账号,在高精度定位服务账号列表中将该账号的使用状态置为空闲;由于车载终端获取到过该账号的密码,为了保证该账号不被盗用,账号管理模块可以向高精度定位平台发起密码修改。In this embodiment, the positioning information is the high-precision position of the vehicle. Specifically, the vehicle-mounted terminal calculates the high-precision position of the vehicle terminal based on the received satellite positioning signal and differential positioning information; wherein, the vehicle-mounted terminal calculates the high-precision position of the vehicle terminal based on the received differential positioning information. 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.
