具体实施方式
为使本申请的技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。在传统的使用蓝牙钥匙控制车辆的过程中，用户终端通过自身安装的应用程序向汽车厂商提供的通信平台，例如汽车远程服务提供商(TSP，Telematics Service Provider)后台***，发送请求，例如鉴权请求或通信请求等，通信平台将鉴权请求或通信请求等发送至车载终端，并接收车载终端反馈的蓝牙钥匙信息。用户终端基于从通信平台接收到的蓝牙钥匙信息与车载终端进行通信，以实现蓝牙钥匙对车辆的控制。采用这种控制方法，蓝牙钥匙的开发和维护成本较高，并且蓝牙钥匙的响应速率也会受到影响。
为解决上述问题，本申请提供一种车辆控制方法，其实施环境包括用户终端和车载终端。用户终端中具备第一蓝牙设备(也称为终端蓝牙模块)，用户可以在该用户终端上触发操作指令。该用户终端例如可以为智能手机、电脑、多媒体播放器、电子阅读器、可穿戴式设备等。车载终端中具备第二蓝牙设备(也称为车载蓝牙模块)，该第二蓝牙设备可以和车身控制模块(BCM，Body Control Module)之间通信连接。直接通过第一蓝牙设备与第二蓝牙设备之间的近场通讯实现蓝牙钥匙的鉴权和车辆控制，开发和维护成本较低，且蓝牙钥匙的响应速率快。
图1是根据一示例性实施例示出的一种车辆控制方法的流程图，该方法可以应用于具备第一蓝牙设备的用户终端，如图1所示，该车辆控制方法包括：
步骤S101、获取目标车辆的车辆识别码和用户终端的终端识别码；其中，目标车辆是指用户终端意图控制的车辆。
步骤S102、基于车辆识别码和终端识别码，控制第一蓝牙设备和第二蓝牙设备连接，其中第一蓝牙设备与终端识别码对应，第二蓝牙设备与车辆识别码 对应；
步骤S103、向第二蓝牙设备发送控制信息，以使目标车辆执行控制信息对应的功能。
本申请实施例提供的车辆控制方法和装置，用户终端直接获取车辆识别码和终端识别码，从而无需经汽车厂商提供的通信平台即可建立用户终端和车载终端之间的绑定关系，实现对用户终端提供的蓝牙钥匙的鉴权；根据该车辆识别码和终端识别码，连接第一蓝牙设备和第二蓝牙设备，并通过第一蓝牙设备直接向第二蓝牙设备发送控制信息，无需经过通信平台中转，从而可以提高蓝牙钥匙的响应速率。
相应地，本申请实施例还提供一种车辆控制方法，该方法可以应用于具备第二蓝牙设备的车载终端，该车辆控制方法包括：
获取目标车辆的车辆识别码和用户终端的终端识别码；
基于车辆识别码和终端识别码，控制车辆识别码对应的第二蓝牙设备和终端识别码对应的第一蓝牙设备连接；
接收第一蓝牙设备发送的控制信息，以使车辆执行控制信息对应的功能。
图2是根据一示例性实施例示出的另一种车辆控制方法的流程图，该方法可以应用于用户终端，如图2所示，该车辆控制方法包括：
步骤S201、获取车辆识别码和终端识别码。
本申请实施例中，用户终端上可以预先安装有用于实现蓝牙钥匙功能的应用程序，通过该应用程序可实现解闭锁、天窗控制、车窗控制、尾门控制、发动机启动和关闭、空调控制等车辆控制功能。
用户终端可以获取自身的终端识别码，该终端识别码可以为IMEI(International Mobile Equipment Identity，国际移动设备识别码)或手机号。当终端识别码为IMEI时，用户可以在用户终端上授权给该应用程序，使该应用程序可以获取用户终端的IMEI。当终端识别码为手机号时，用户可以使用手机号注册或登陆该应用程序，以使该应用程序获取手机号。用户可以通过在该应用程序中输入目标车辆的车辆识别号码(Vehicle Identification Number，VIN)，以使用户终端获取车辆识别码，从而用户终端可以建立并存储终端识别码和车辆识别号码之间的绑定关系。
相应地，车载终端也可以获取车辆识别码和终端识别码。用户可以在目标 车辆的HU(Head Unit，主控单元)中输入用户终端的终端识别码，并且车载终端中的第二蓝牙设备可以通过整车CAN网络获取目标车辆的车辆识别号码以及用户输入的终端识别码，从而车载终端可以建立并存储终端识别码和车辆识别号码之间的绑定关系。基于终端识别码和车辆识别号码之间的绑定关系，可以实现对用户终端提供的蓝牙钥匙的鉴权。
步骤S202、基于车辆识别码和终端识别码，生成第一配对秘钥。
本申请实施例中，可选地，在生成第一配对密钥之前，基于车辆识别码和终端识别码，生成鉴权密钥。换言之，生成第一鉴权秘钥可包括：基于车辆识别码和终端识别码，生成鉴权密钥；基于鉴权秘钥和车辆识别码生成第一配对秘钥。通过对车辆识别码和终端识别码的二次加密，可以提高配对秘钥的加密级别，保证信息的安全性。
在具体的实施例中，用户终端可以将车辆识别码和终端识别码作为加密因子，通过第一加密算法生成鉴权密钥。第一配对秘钥可以为编码后的车辆识别码，其中固定位置处的字符串以该鉴权密钥作为加密因子，通过第二加密算法生成。也即，将鉴权密钥和车辆识别码作为加密因子，通过第二加密算法生成第一配对秘钥。第二加密算法和第一加密算法可以相同，也可以不同。

第二蓝牙设备将接收到的状态信息发送给车载终端，用户终端通过第一蓝牙设备接收该状态信息后，可以根据该状态信息更新应用程序中显示的目标车辆状态。例如，当目标车辆基于用户触发的操作指令打开天窗后，应用程序中也动画的形式显示目标车辆打开天窗的过程。
需要说明的是，本申请实施例提供的车辆控制方法，车载终端可以和多个用户终端进行通信。即第二蓝牙设备可以连接多个第一蓝牙设备，每个第一蓝牙设备的第一配对秘钥不同。从而，第一配对秘钥可以为作为终端蓝牙模块的身份ID的一部分。本申请的其他实施例中，也可以采用鉴权秘钥作为每个终端蓝牙模块的身份ID的一部分。
第二蓝牙设备连接多个第一蓝牙设备后，可以为该多个第一蓝牙设备对应的用户终端设置优先级。例如用户可以在HU的设置界面中为每个第一蓝牙设备对应的用户终端设置优先级。第二蓝牙设备接收到来自多个用户终端的操作信息后，可以根据操作信息中携带的第一配对秘钥或身份信息，确定该操作信息对应的用户终端的优先级。根据用户终端的优先级确定多个操作信息的执行 顺序。优先级较高的用户终端发送的操作信息可以先执行。
通过为多个用户终端设置优先级，可以在车载终端接收到大量操作信息，或多个操作信息之间相互矛盾时，提高对用户终端提供的蓝牙钥匙的响应速率。
