具体实施方式
本申请实施例提供了一种对车载终端进行功能辅助的方法，该方法可以由对车载终端进行功能辅助的系统实现。如图1所示，该系统包括移动终端、车载终端和服务器。其中，移动终端可以为手机、平板电脑、笔记本电脑等。车载终端设置在车辆上，由车载网关、T-Box、人机界面(Human Machine Interface，HMI)、处理器、底盘控制系统以及自动驾驶系统(Automated Driving System，ADS)等组成。服务器可以提供程序升级、行车数据存储等多种功能。
T-Box用于与服务器建立通信联系，以实现车载终端和服务器之间的交互。车载网关可以具有无线通信功能，具体的，可以具有，Wi-Fi通信功能、蓝牙通信功能等，该车载网关用于与移动终端建立通信连接，以实现车载终端和移动终端之间的交互。底盘控制系统用于实现对底盘的控制，具体的，可以为刹车、加速、转向等等。自动驾驶系统用于实现对车辆的定位、行驶导航、行驶策略计算等等。HMI用于显示用户操作界面，处理器用于获取并执行用户通过HMI发送的指令。
参见图2，在本申请实施例中，车载终端启动后，车载终端和移动终端建立通信连接，然后，车载终端通过服务器进行鉴权。如果鉴权通过，则将移动终端作为车载终端的一部分，辅助车载终端实现程序升级、车辆控制、行车数据转存、辅助计算等。具体的，程序升级又包括固件升级、高精度地图升级等，其中，固件是一种嵌入在硬件设备中的软件。车辆控制又包括车辆诊断、刹车指令下发等。辅助计算可以包括辅助V2X业务实现。
通过本申请，用户除了可以通过车载终端实现对车辆的程序升级、驾驶控制等，还可以通过移动终端实现对车辆的程序升级、驾驶控制等，这样，给予了用户更多的选择空间和使用体验。此外，移动终端还可以使用本身强大的计算能力辅助车载终端进行数据计算，使得车载终端在硬件计算能力较弱的情况下，仍然可以快速得到计算结果，节省了对车载终端硬件的成本。
参见图3，是本申请实施例提供的一种车载终端进行功能辅助的方法，该方法由上述对车载终端进行功能辅助的系统实现，该方法的处理流程可以包括如下步骤：
步骤201、移动终端与车载终端之间建立通信连接。
其中，通信连接可以为无线连接，如Wi-Fi连接或者蓝牙连接等，还可以为有线连接，例如通过数据线连接。
在实施中，用户在需要使用移动终端对车载终端进行辅助时，可以使用数据线连接移动终端和车载终端，实现移动终端和车载终端之间的通信连接。还可以打开移动终端的无线连接功能，使移动终端发出无线信号，车载终端的车载网关接收到无线信号后，与移动终端建立通信连接，该通信连接为无线连接。
对于通信连接为无线连接的情况，例如，用户可以打开移动终端的Wi-Fi共享功能，该Wi-Fi共享功能也可称为Wi-Fi热点，然后，移动终端发出Wi-Fi信号，车载终端的车载网关接收到Wi-Fi信号后，与移动终端建立Wi-Fi连接。又例如，用户可以打开移动终端的蓝牙功能，然后，移动终端发出蓝牙信号，车载终端的车载网关接收到蓝牙信号后，与移动终端 建立蓝牙连接。
在一种可能的实现方式中，为了保障车载终端和移动终端之间通信连接质量，车载终端可以在多个通信连接中选择一个作为主连接，其他通信连接作为备用连接。
在实施中，用户可以打开移动终端中的多个无线连接功能，例如，Wi-Fi、蓝牙等。相应的，移动终端会发出多个无线信号。车载终端的车载网关在接收到多个无线信号后，对应这多个无线信号，分别与移动终端之间建立通信连接。然后，车载网关可以通过与移动终端之间发送检测数据包的形式，来检测多个通信连接的通信质量，其中，通信质量可以以数据传输时延等参数进行评价。例如，数据传输时延越低，则判断该通信链路的通信质量越高。最后，车载网关可以在多个通信连接中选择通信质量最好的一个通信连接作为主连接，其余的通信连接作为备用连接。
然后，车载网关可以向移动终端发送主连接设置消息，移动终端接收到该主连接设置消息后，将传输该主连接设置消息的通信连接设置为主连接。这样，在后续移动终端和车载终端之间的数据交互均优先使用主连接，在主连接断开的情况下，再主动切换到备用连接进行数据交互。
另外，车载网关可以每过预设时长，对已建立的多个通信连接进行通信质量的检测，重新选择出主连接。预设时长可以由技术人员根据实际情况进行设置，例如，预设时长可以设置为30分钟、60分钟等。在每次重新选择主连接后，如果本次选择的主连接与上一次选择的主连接不同，则车载网关可以通过新选择的主连接向移动终端发送主连接设置消息，移动终端接收到该主连接设置消息后，将传输该主连接设置消息的通信连接设置为主连接。如果本次选择的主连接与上一次选择的主连接相同，则车载网关无需再次向移动终端发送主连接设置消息。
下面以多个通信连接包括Wi-Fi连接和蓝牙连接为例，对主连接的设置进行说明：
用户同时打开了移动终端Wi-Fi共享功能和蓝牙功能，然后，移动终端发出Wi-Fi信号和蓝牙信号，车载终端的车载网关接收到蓝牙信号后，与移动终端建立蓝牙连接，接收到Wi-Fi信号后，与移动终端建立Wi-Fi连接。当两个通信连接均建立后，车载网关可以检测Wi-Fi连接和蓝牙连接的数据传输时延，将数据传输时延低的通信连接，设置为主连接，将另一个设置为备用连接。在预设时长后，如果两个通信连接仍然存在，则车载网关可以再次检测两个通信连接的数据传输时延，并将数据传输时延低的通信连接，设置为主连接，将另一个设置为备用连接。假设检测Wi-Fi连接的数据传输时延较低，则车载网关将Wi-Fi连接设置为主连接。然后，车载网关通过Wi-Fi连接向移动终端发送主连接设置消息，移动终端接收到该主连接设置消息后，将Wi-Fi连接设置为主连接。
在预设时长后，车载网关再次检测Wi-Fi连接和蓝牙连接的数据传输时延，将数据传输时延低的通信连接，设置为主连接，将另一个设置为备用连接。如果本次检测蓝牙连接数据传输时延较低，则车载网关将蓝牙连接设置为主连接，并通过蓝牙连接向移动终端发送主连接设置消息，移动终端接收到该主连接设置消息后，将蓝牙连接设置为主连接。如果本次检测Wi-Fi连接数据传输时延较低，则确定本次选择的主连接和上一次选择的主连接相同，则车载网关不再向移动终端发送主连接设置消息。
此外，还需说明的是，上述对主连接的设置也可以由移动终端实现。具体的，可以如下：
用户打开移动终端中的多个无线连接功能，相应的，移动终端会发出多个无线信号，车 载终端的车载网关在接收到多个无线信号后，对应这多个无线信号，分别与移动终端之间建立通信连接。然后，移动终端可以通过与车载终端之间发送检测数据包的形式，来检测多个通信连接的通信质量。最后，移动终端可以在多个通信连接中选择通信质量最好的一个通信连接作为主连接，其余的通信连接作为备用连接。此外，移动终端还可以通过主连接向车载终端发送主连接设置消息，车载终端接收到该主连接设置消息后，将传输该主连接设置消息的通信连接设置为主连接。
此外，移动终端还可以通过主连接向车载终端发送主连接设置消息，车载终端接收到该主连接设置消息后，将传输该主连接设置消息的通信连接设置为主连接。这样，在后续移动终端和车载终端之间的数据交互均优先使用主连接，在主连接断开的情况下，再主动切换到备用连接进行数据交互。
另外，移动终端可以每过预设时长，对已建立的多个通信连接进行通信质量的检测，重新选择出主连接。如果本次选择的主连接与上一次选择的主连接不同，则移动终端可以通过新选择的主连接向车载终端发送主连接设置消息，车载终端接收到该主连接设置消息后，将传输该主连接设置消息的通信连接设置为主连接。如果本次选择的主连接与上一次选择的主连接相同，则移动终端无需再次向车载终端发送主连接设置消息。
步骤202、服务器向移动终端发送目标程序的升级包，其中，目标程序为车载终端安装的程序。
目标程序可以为移动终端的固件，如移动终端中HMI的固件、ADS的固件、底盘控制系统的固件。目标程序还可以为车载终端中安装的应用程序，如高精度地图应用程序。
在实施中，该步骤202实现的前提为移动终端安装有辅助应用程序，并且该辅助应用程序已经在服务器中完成了注册和登录。此外，该辅助应用程序登录的账号还需要与车辆之间存在绑定关系。为了便于对该步骤202的实施方式的说明，下面先对辅助应用程序的账号注册、辅助应用程序的账号与车辆绑定以及辅助应用程序的账号登录进行说明：
一、辅助应用程序的注册，参见图4，辅助应用程序的注册可以包括如下步骤：
S2021、移动终端获取辅助应用程序账号、辅助应用程序密码、车辆标识和用户身份信息。
其中，车辆标识为唯一标识一台车辆的信息，如车辆的车架号，用户身份信息可以为身份证号。
在实施中，用户可以启动移动终端中安装的辅助应用程序，辅助应用程序开启后，如果当前该辅助应用程序还未登录任何账户，则显示初始界面。在初始界面中显示有注册选项和登录选项。如果需要注册账户，则可以选择注册选项。移动终端检测到用户对注册选项的选择操作后，可以使辅助应用程序跳转到注册界面。其中，选择操作可以为点击操作、长按操作、滑动操作等等。
在注册界面中可以显示有账号输入框、密码输入框、车辆标识输入框、用户身份信息输入框以及确认选项。例如，车辆标识为车架号，用户身份信息为身份证号，相应的，辅助应用程序的注册界面中显示有账号输入框、密码输入框、车架号输入框、身份证号输入框以及注册选项。
用户在账号输入框中输入辅助应用程序账号，在密码输入框中输入辅助应用程序密码，在车辆标识输入框中输入车辆标识，在用户身份信息输入框中输入用户身份信息，在确认输入信息正确的情况下，用户可以点击确认选项。用户点击确认选项后，移动终端获取用户输 入的辅助应用程序账号、辅助应用程序密码、车辆标识和用户身份信息。
S2022、移动终端向服务器发送注册请求，该注册请求中携带辅助应用程序账号、辅助应用程序密码、车辆标识和用户身份信息。
在实施中，移动终端在获取到用户输入的辅助应用程序账号、辅助应用程序密码、车辆标识和用户身份信息后，基于向服务器发送注册请求，该注册请求中携带有辅助应用程序账号、辅助应用程序密码、车辆标识和用户身份信息。
S2023、服务器对车辆标识和用户身份信息进行验证。
在实施中，车辆在出售后，用户首次开启车载终端时，需要在车载终端中完成用户注册。在首次开启车载终端后，在车载终端的显示屏可以显示用户注册界面。该用户注册界面中可以显示有用户身份信息账号输入框、密码输入框、车辆标识输入框、用户身份信息输入框以及确认选项。
用户在账号输入框中输入车载终端应用账号，在密码输入框中输入车载终端应用密码，在车辆标识输入框中输入第一车辆标识，在用户身份信息输入框中输入第一用户身份信息，在确认输入信息正确的情况下，用户可以点击确认选项。用户点击确认选项后，车载终端获取用户输入的车载终端应用账号、车载终端应用密码、车辆标识和用户身份信息。然后，车载终端通过T-Box向服务器发送用户注册请求，该用户注册请求中携带有车载终端应用账号、车载终端应用密码、车辆标识和用户身份信息。
服务器接收到用户注册请求后，将车载终端应用账号、车载终端应用密码、第一车辆标识和第一用户身份信息作为车辆注册信息对应存储。其中，车载终端应用账号和车载终端应用密码用于对车载终端的登录验证。车辆标识和用户身份信息用于对辅助应用程序的注册验证。
然后，服务器向车载终端发送用户注册成功消息。车载终端在完成注册后自动登录注册的账户，并且在之后每次开启车载终端后，车载终端均可以自动登录上述注册的账户。
在车载终端完成用户注册的基础上，服务器可以基于车辆注册信息中的车辆标识和用户身份信息的对应关系，对辅助应用程序的注册请求中携带的车辆标识和用户身份信息进行验证。
具体的，服务器可以确定在存储的车辆注册信息中车辆标识和用户身份信息的对应关系中，是否对应存储有辅助应用程序的注册请求中携带的车辆标识和用户身份信息。
S2024、如果验证通过，则服务器将辅助应用程序账号和辅助应用程序密码对应存储，并向移动终端发送注册成功消息。
在实施中，如果服务器确定在车辆注册信息中车辆标识和用户身份信息的对应关系中，对应存储有注册请求中携带的车辆标识和用户身份信息，则认为验证通过。然后，服务器可以将辅助应用程序账号和辅助应用程序密码作为辅助应用程序的注册信息对应存储，并向移动终端发送注册成功消息。
在实施中，如果服务器确定在存储的车辆注册信息中车辆标识和用户身份信息的对应关系中，未对应存储有注册请求中携带的车辆标识和用户身份信息，则认为验证未通过，并向移动终端发送注册识别消息。
S2025、如果验证未通过，则服务器向移动终端发送注册失败消息。
二、对辅助应用程序的账号与车辆进行绑定。
在上述步骤S204的基础上，服务器将辅助应用程序的辅助应用程序账号，以及车辆注册信息中车辆标识和用户身份信息共同对应的车载终端应用账号对应存储。或者，服务器将辅助应用程序的辅助应用程序账号和车辆注册信息中车辆标识对应存储。通过这两种方式，均可以实现对辅助应用程序和车辆进行绑定。
三、辅助应用程序的登录，该登录过程也可以认为是移动终端通过服务器进行鉴权的过程。参见图5，辅助应用程序的登录可以包括如下步骤：
S2026、移动终端获取辅助应用程序账号和辅助应用程序密码。
在实施中，用户可以启动移动终端中安装的辅助应用程序，辅助应用程序开启后，如果当前该辅助应用程序还未登录任何账户，则显示初始界面。在初始界面中显示有注册选项和登录选项。如果需要登录账户，则可以选择登录选项。移动终端检测到用户对登录选项的选择操作后，可以使辅助应用程序跳转到登录界面。
在登录界面中可以显示有账号输入框、密码输入框和确认选项。用户在账号输入框中输入辅助应用程序账号，在密码输入框中输入辅助应用程序密码，在确认输入信息正确的情况下，用户可以点击确认选项。用户点击确认选项后，移动终端获取用户输入的辅助应用程序账号和辅助应用程序密码。
S2027、移动终端向服务器发送登录请求，该登录请求中携带辅助应用程序账号和辅助应用程序密码。
在实施中，移动终端在获取到用户输入的辅助应用程序账号和辅助应用程序密码后，向服务器发送该登录请求，其中，登录请求中携带有辅助应用程序账号和辅助应用程序密码。
S2028、服务器对辅助应用程序账号和辅助应用程序密码进行验证。
在实施中，服务器确定在存储的辅助应用程序的注册信息中辅助应用程序账号和辅助应用程序密码对应关系中，是否对应存储有登录请求中携带的辅助应用程序账号和辅助应用程序密码。
S2029、如果验证通过，则服务器向移动终端发送验证成功消息。
在实施中，如果服务器确定在存储的辅助应用程序的注册信息中辅助应用程序账号和辅助应用程序密码对应关系中，对应存储有登录请求中携带的辅助应用程序账号和辅助应用程序密码，则认为验证通过，并向移动终端发送验证成功消息。
S2030、如果验证未通过，则服务器向移动终端发送验证失败消息。
在实施中，如果服务器确定在存储的辅助应用程序的注册信息中辅助应用程序账号和辅助应用程序密码对应关系中，未对应存储有登录请求中携带的辅助应用程序账号和辅助应用程序密码，则认为验证失败，并向移动终端发送验证失败消息。
在上述移动终端中安装的辅助应用程序完成注册、登录以及和车辆之间绑定的基础上，移动终端可以作为车载终端的一部分，与车载终端共用自身的算力，以辅助车载终端实现多种功能，如程序升级、车辆控制、行车数据转存和辅助计算等。下面分别对移动终端辅助车载终端实现程序升级、车辆控制、行车数据转存和辅助计算进行说明。

在该方法中，服务器可以记录有各车载终端安装的程序的已安装版本标识。车载终端每次对程序进行升级后，可以向服务器发送对该程序的升级成功消息。服务器接收到该升级通知消息后，可以将记录的该程序的已安装版本标识进行更新，以使得服务器可以获知各移动终端中安装的程序的已安装版本。
具体的，服务器可以记录车辆标识和车载终端安装的程序的已安装版本标识的对应关系，或者，可以记录车载终端对应的账号和车载终端安装的程序的已安装版本标识的对应关系。对于每个程序，可以单独记录车辆标识与车载终端中安装的该程序的已安装版本标识的对应关系，或者可以单独记录车载终端对应的账号与车载终端中安装的该程序的已安装版本标识的对应关系。
如下表1所示，为车辆标识和车载终端安装的第一固件的已安装版本标识的对应关系示例。

Figure PCTCN2022073241-appb-000001
下面仅以服务器中记录车辆标识和车载终端安装的程序的已安装版本标识的对应关系的情况，对该方法二的实施方式进行说明。参见图8，该方法二可以包括如下步骤：
S230、服务器获取目标程序的升级包和最新版本标识。
在实施中，当目标程序有升级时，技术人员可以向服务器上传目标程序的升级包以及对 应的最新版本号。
S231、服务器在存储的车辆标识和车载终端安装的目标程序的已安装版本标识的对应关系中，确定与目标程序的最新版本标识不同的已安装版本标识对应的目标车辆标识。
在实施中，服务器接收到目标程序的升级包和最新版本标识后，可以在存储的车辆标识和车载终端安装的目标程序的已安装版本标识的对应关系中，查询各车载终端中安装的目标程序的已安装版本标识。并确定出与目标程序的最新版本标识不同的已安装版本标识对应的目标车辆标识。
S232、服务器在存储的车辆标识和辅助应用程序的账号的对应关系中，确定目标车辆标识对应的辅助应用程序的目标账号。
S233、服务器向登录目标账号的移动终端发送对应目标程序的升级消息。
在实施中，服务器确定目标账号处于登录状态，则可以向登录该目标账号的移动终端发送对应目标程序的升级消息。
S234、移动终端显示对应目标程序的升级选项。
在实施中，移动终端确定目标程序的已安装版本标识与最新版本标识不同，则可以显示对应目标程序的升级提示框，以提醒用户目标程序需要进行升级。用户可以选择在合适的时机，点击该目标程序的升级提示框，使辅助应用程序跳转到程序升级界面，在该程序升级界面中，可以显示有对应目标程序的升级选项。
S235、移动终端当检测到对应目标程序的升级选项触发时，向服务器发送对应目标程序的升级包获取请求。
在实施中，用户可以对该对应目标程序的升级选项执行选择操作，移动终端检测到对应目标程序的升级选项的选择操作后，向服务器发送对应目标程序的升级包获取请求。
S236、服务器向移动终端发送目标程序的升级包。
在实施中，服务器接收到对应目标程序的升级包获取请求后，将目标程序的升级包发送至移动终端。
步骤203、移动终端向车载终端发送目标程序的升级包。
在实施中，移动终端在接收到服务器发送的目标程序的升级包后，可以显示升级包下载成功提示框，以提醒用户目标程序的升级包下载完成。用户可以通过点击该升级包下载成功提示框的方式，使辅助应用程序跳转到升级包发送界面，在该升级包发送界面中可以显示有升级包发送选项。用户可以在车载终端和移动终端已经建立通信连接的情况下，点击该升级包发送选项，以触发移动终端将该目标程序的升级包发送至车载终端。
车载终端的车载网关接收到目标程序的升级包后，发送至车载终端的处理器。车载终端的处理器根据该目标程序的升级包对安装的目标程序进行升级。
例如，如图9所示，如果目标程序为底盘控制系统的固件，则处理器接收到该升级包后，根据该升级包对底盘控制系统的固件进行升级。如果目标程序为HMI的固件，则处理器接收到该升级包后，根据该升级包对HMI的固件进行升级。如果目标程序为T-Box的固件，则处理器接收到该升级包后，根据该升级包对T-Box的固件进行升级。如果目标程序为ADS的固件，则处理器接收到该升级包后，根据该升级包对ADS的固件进行升级。
又例如，如图10所示，目标程序为高精度地图应用程序，则升级包可以为加密的高精度地图包，处理器接收到该加密的高精度地图包后，先对该加密的高精度地图包进行解压，再 将解压后的高精度地图包更新到ADS的高精度地图应用程序中。
二、移动终端辅助车载终端实现车辆控制：
具体的，车辆控制可以包括对车辆的行驶控制、对车辆的车辆诊断等。
在实施中，在车载终端和移动终端之间已经建立连接的基础上，如果车载终端的显示界面故障，用户无法通过车载终端控制车辆。在此情况下，用户可以通过移动终端向车载终端发送对车辆的车辆控制指令，车载终端接收到该车辆控制指令后，可以向相应系统发送控制命令，以实现对车辆的控制。
具体的，用户可以打开移动终端中的辅助应用程序，在辅助应用程序的功能界面中，可以显示有多个车辆控制选项。用户可以根据实际需求，点击目标车辆控制选项。移动终端当检测到所述多个车辆控制选项中目标车辆控制选项触发时，确定目标车辆控制选项对应的车辆控制指令，并向车载终端发送该车辆控制指令。车载终端接收到该车辆控制指令后，可以执行该车辆控制指令，对车辆进行相应控制。下面分别针对目标车辆控制选项为刹车选项和车辆诊断选项为例，对移动终端辅助车载终端进行车辆控制进行说明。
目标车辆控制选项为刹车控制选项：
用户点击刹车选项，移动终端检测到用户对刹车选项的点击操作后，向车载终端的车载网关发送刹车指令。车载网关可以将接收到的紧急刹车指令转发至车载终端的处理器，处理器再根据该紧急刹车指令向底盘控制系统发送刹车命令。底盘控制系统接收到刹车命令后，响应该刹车命令，控制相应部件实现对车辆的刹车。
目标车辆控制选项为车辆诊断选项：
用户点击车辆诊断选项，移动终端检测到用户对车辆诊断选项的点击操作后，向车载终端的车载网关发送车辆诊断指令。如图11所示，车载网关可以将接收到的车辆诊断指令转发至车载终端的处理器，处理器再根据该车辆诊断指令分别向底盘控制系统、ADS、T-Box等发送诊断命令。各系统或部件接收到诊断命令后，执行相应的诊断操作，并向处理器返回诊断结果。处理器接收到各系统或部件返回的诊断结果后，将全部诊断结果作为车辆诊断结果通过车载网关发送至移动终端。移动终端接收到车辆诊断结果后，可以通过辅助应用程序显示车辆诊断结果以便用户查看。此外，移动终端还可以将车辆诊断结果进行存储。
三、移动终端辅助车载终端进行行车数据的转存：
在实施中，为了防止车辆黑匣子出现损坏而导致行车数据丢失，车辆黑匣子可以在每个转存周期结束时，将当前转存周期采集的行车数据发送至车载终端，车载终端通过车载网关将行车数据发送至移动终端，移动终端对行车数据进行存储。此外，在移动终端登录辅助应用程序的情况下，可以将行车数据转发至服务器。服务器接收到行车数据后，先根据辅助应用程序登录的账号以及存储的辅助应用程序的账号和车辆标识的对应关系，确定出该辅助应用程序登录的账号对应的车辆标识，然后将行车数据和车辆标识对应存储。
这样，在后续车辆出行事故时，即使车辆黑匣子故障行车数据丢失，也可以通过移动终端以及服务器获取到车辆的行车数据进行事故判定等。
四、移动终端辅助车载终端进行业务数据计算：
在实施中，考虑到目前移动终端的计算能力较强，而车载终端的计算能力又相对较弱，且车载终端的硬件升级成本较高。因此，在本申请实施例中，通过移动终端辅助车载终端进行业务数据计算，使得在不更换车载终端硬件的情况上，提高业务数据的计算效率。
车载终端在需要进行业务数据计算时，如果检测到本地的可用计算资源不足，且当前和移动终端之间建立了通信连接，则可以通过车载网关向移动终端发送数据处理请求。其中，数据处理请求中携带有待处理业务数据和业务类型标识。移动终端接收到数据处理请求后，通过数据处理请求中携带的业务类型标识对应的业务执行程序，对该待处理数据进行处理，得到输出数据，并将输出数据发送至车载终端。其中，业务执行程序可以为上述辅助应用程序的功能模块，也可以为一个独立的应用程序。
上述业务类型标识可以为车联网(vehicle to everything，V2X)业务标识，相应的，待处理业务数据可以为摄像头，雷达，超声波，温度传感器等传感器数据。上述业务类型标识还可以为三维建模业务标识，相应的，待处理业务数据可以为二维地图数据等。
基于相同的技术构思，本申请实施例还提供了一种对车载终端进行功能辅助的装置，如图12所示，该装置包括：
