本申请要求在2021年04月25日提交中国专利局、申请号为202110448849.5、申请名称为“一种远程控制方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及车联网技术领域，尤其涉及一种远程控制方法及装置。
背景技术
随着车联网技术的发展，远程控制功能在车辆中的应用越来越普遍。当车辆支持远程控制功能时，用户能通过手机控制车辆中部件的一些行为。例如，在炎热的夏天或寒冷的冬天，用户在上车之前可以先通过手机启动车内空调，待空调将车内温度调节至适宜后再开门上车。又例如，用户在需要用车时也可以先通过手机召唤车辆，让车辆自动行驶至用户当前所在的位置后直接上车，而不用再步行至车辆所在的位置上车。可见，通过使车辆支持远程控制功能，能有效提高用户使用车辆的舒适性和便捷性。
然而，现有技术中的远程控制流程通常如下：用户通过手机向车辆管理服务器发出远程控制的相关指令，车辆管理服务器接收到相关指令后，先向车辆发送唤醒短消息，并等待车辆返回的唤醒成功响应，之后，如果接收到唤醒成功响应，则再向车辆发送远程控制命令，并等待车辆返回的控制结果，将控制结果通过手机返回给用户。然而，采用该方式，用户在发出远程控制的相关指令后，要经过很长时间才能获知到控制结果，导致远程控制的时延较长，不利于用户的使用体验。基于此，如何降低远程控制的时延，成为目前亟待解决的一个技术问题。
发明内容
本申请提供一种远程控制方法及装置，用以降低远程控制的时延。
第一方面，本申请提供一种远程控制方法，该方法应用于车辆中的通信模块，该方法包括：在通信模块处于支持远程唤醒功能的休眠状态时，接收唤醒命令和远程控制命令，根据唤醒命令，使通信模块进入唤醒状态，以及，根据远程控制命令，向车辆内的部件发送控制消息，以启动车辆内的部件或者指示车辆内的部件执行远程控制命令指示的操作。在该设计中，通过在车辆的通信模块处于休眠状态时将远程控制命令发送给通信模块，有助于通信模块在唤醒车内部件后立即执行远程控制，有效避免等待车内部件唤醒响应后再发送远程控制命令所引入的时延，有助于提高远程控制的及时性。
在一种可能的设计中，远程控制命令可以为国际互连协议(internet protocol，IP)数据包，唤醒命令可以为短消息或者IP数据包。在该设计中，通过采用IP数据包的网络方式发送远程控制命令或唤醒命令，相比于短消息发送方式来说，能节省命令经运营商侧的短消息中心转发所引入的短消息转发时延，有助于进一步降低远程控制车辆的时延。且， 即使通过短消息发送唤醒命令，由于在通信模块被唤醒之前先以IP数据包的形式发送了远程控制命令，因此也能尽量保证通信模块连续执行唤醒和远程控制。
在一种可能的设计中，唤醒命令和远程控制命令可以在同一个IP数据包中发送给通信模块，也可以在连续的两个IP数据包中发送给通信模块。该设计能尽量使通信模块在同一时刻接收到唤醒命令和远程控制命令，有助于实现通信模块在唤醒后立即执行远程控制的方案。
在一种可能的设计中，唤醒命令和远程控制命令可以是车辆管理服务器发送给通信模块的，该设计有助于实现车辆管理服务器对车辆远程控制的灵活管理，以及对不同车辆远程控制的集中管理。
在一种可能的设计中，唤醒命令和远程控制命令可以是登录车辆管理服务器的用户终端发送给通信模块的，该设计可以节省经由车辆管理服务器转发命令所引入的转发时延，进一步降低远程控制的时延。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以登录车辆管理服务器，以建立与车辆管理服务器的连接，便于车辆管理服务器通过该连接将唤醒命令和远程控制命令发送给通信模块。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以周期性地将通信模块的有效网络地址发送给车辆管理服务器。该设计能使车辆管理服务器尽量获取到车辆管理服务器的最新的网络地址，提高发送唤醒命令或远程控制命令的成功率。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以将通信模块的更新的网络地址发送给车辆管理服务器。该设计能使车辆管理服务器及时获取到通信模块变化的网络地址，提高发送唤醒命令或远程控制命令的成功率。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以周期性地向车辆管理服务器发送心跳数据包，该心跳数据包用于维持车辆管理服务器与通信模块的长连接。该设计有助于车辆管理服务器通过长连接向通信模块发送唤醒命令和远程控制命令，而可以不再重新建立连接，有效节省网络资源。
在一种可能的设计中，心跳数据包中可以包含通信模块的有效网络地址或更新的网络地址。在该设计中，同步网络地址的操作可以放在维持长连接的流程中一起实现，而可以不再额外浪费资源单独执行同步网络地址的操作，有助于节省网络资源。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以向车辆管理服务器发送更新后的密钥，该更新后的密钥可以用于通信模块和车辆管理服务器的后续通信，如以加密的方式发送唤醒命令和远程控制命令。相应地，在通信模块接收到唤醒命令和远程控制命令之后，若唤醒命令和远程控制命令为加密的数据包，则还可以使用先更新后的密钥解密该数据包，以得到明文的唤醒命令和远程控制命令。通过以加密方式发送唤醒命令和远程控制命令，有助于提高远程控制的安全性。
在一种可能的设计中，在通信模块接收唤醒命令和远程控制命令之前，还可以周期性地与车辆管理服务器进行鉴权认证。在该设计中，通过车辆管理服务器周期检测通信模块的合法性，能只在合法的情况下向通信模块发送唤醒命令和远程控制命令，在不合法的情况下不执行远程控制，有效提高远程控制的安全性。且，通过采用周期方式进行鉴权认证，还能在需要执行远程控制时直接发送唤醒命令和远程控制命令，而可以不再重新鉴权认证，进一步提高远程控制的效率。
第二方面，本申请提供一种远程控制方法，该方法适用于具有处理能力的任一设备，如车辆管理服务器。以车辆管理服务器为例，该方法包括：车辆管理服务器从用户终端接收第一远程控制命令，基于第一远程控制命令，向车辆发送唤醒命令，以使车辆中的通信模块进入唤醒状态，在通信模块处于支持远程唤醒功能的休眠状态时，基于第一远程控制命令，向车辆发送第二远程控制命令，以指示车辆内的部件启动或者执行第一操作。
在一种可能的设计中，第二远程控制命令可以为IP数据包，唤醒命令可以为短消息或者IP数据包。
在一种可能的设计中，车辆管理服务器可以将唤醒命令和远程控制命令放在同一个IP数据包中发送给通信模块，也可以分别将唤醒命令和远程控制命令放在连续的两个IP数据包中发送给通信模块。
在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以接受通信模块的登录。
在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以周期性地从通信模块接收通信模块的有效网络地址。
在一种可能的设计中，当车辆管理服务器周期性地从通信模块接收通信模块的有效网络地址时，若在超过一个周期的时长内未接收到新的有效网络地址，则车辆管理服务器将通信模块的网络地址设置为无效状态。在该设计中，无效状态意味着车辆管理服务器与通信模块之间的网络链路中断，通过更新通信模块的网络地址的状态，能使车辆管理服务器及时获知网络链路的状态，便于决策后续的命令发送方式。
在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以获取通信模块的网络地址信息的状态，若处于有效状态，则根据有效的网络地址信息将唤醒命令和第二远程控制命令发送给通信模块，若处于无效状态，则将唤醒短消息发送给通信模块。在该设计中，通过在车辆管理服务器与通信模块的网络链路质量较好时以IP数据包的形式唤醒通信模块，能提高唤醒车辆和远程控制车辆的效率。且，通过在车辆管理服务器与通信模块的网络链路中断时以短消息形式唤醒通信模块，不仅能以常规形式成功唤醒车辆，还能节省不必要的通信开销。由此可知，该设计能兼顾远程控制的效率和成功率。
在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以从通信模块接收通信模块的更新的网络地址。
在一种可能的设计中，车辆管理服务器在从用户终端接收第一远程控制命令之前，还可以将通信模块的网络地址发送给所述用户终端。
在一种可能的设计中，车辆管理服务器在确定用户终端登录车辆管理服务器后，还可以周期性地将通信模块的有效网络地址发送给用户终端，或者在有预设事件触发时将通信模块的当前网络地址发送给用户终端，其中的预设事件例如可以为通信模块的网络地址发生更新，以便车辆管理服务器将通信模块的更新的通信模块的网络地址发送给用户终端。该方式能使用户终端及时获知通信模块的最新网络地址，便于用户终端直接基于最新网络地址向通信模块发送唤醒命令和第三远程控制命令，节省经由车辆管理服务器的转发时延，进一步提高远程控制的效率。
在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以周期性地从通信模块接收心跳数据包。
在一种可能的设计中，心跳数据包中可以包含通信模块的有效网络地址或更新的网络地址。

在一种可能的设计中，车辆管理服务器在发送唤醒命令和发送第二远程控制命令之前，还可以周期性地与通信模块进行鉴权认证。
在一种可能的设计中，车辆管理服务器在向车辆发送唤醒命令的同时，还可以向车辆发送唤醒短消息。在该设计中，由于短消息的无线覆盖效果优于数据业务的网络覆盖效果，因此，通过同时以网络形式和短信形式向通信模块发送唤醒命令，既能在网络较好的情况下快速地将唤醒命令传递给通信模块，提高唤醒通信模块的效率，又能在网络不好的情况下通过网络覆盖效果更优的唤醒短消息成功唤醒通信模块。
第三方面，本申请提供一种远程控制方法，该方法适用于具有用户交互能力的任意设备，如用户终端。以用户终端为例，该方法包括：用户终端从车辆管理服务器接收车辆中的通信模块的网络地址，在通信模块处于支持远程唤醒功能的休眠状态时，根据网络地址，向车辆发送第三远程控制命令，第三远程控制命令用于指示车辆内的部件启动或者执行第一操作。在该设计中，通过用户终端直接唤醒和控制车辆，不仅有助于降低经由车辆管理服务器间接转发唤醒命令和远程控制命令所引入的时延，有效提高远程控制的效率，还能尽量分散车辆管理服务器的工作压力。
在一种可能的设计中，用户终端还可以根据网络地址向车辆发送唤醒命令，以使通信模块进入唤醒状态。在该设计中，通过以网络形式发送唤醒命令，能节省唤醒命令经由短信中心转发所引入的转发时延，有助于进一步提高远程控制的效率。
在一种可能的设计中，用户终端还可以向车辆管理服务器发送第一远程控制命令，以便车辆管理服务器根据第一远程控制命令以网络形式或短消息形式指示车辆内的部件启动或者执行第一操作。在该设计中，通过以用户终端的网络形式、用户终端的短信形式、车辆管理服务器的网络形式和车辆管理服务器的短信形式中的至少两项向通信模块发送唤醒命令和远程控制命令，能通过多种发送方式提高通信模块接收到唤醒命令的概率，提高成功唤醒车辆的可能性。
在一种可能的设计中，用户终端可以周期性地从车辆管理服务器接收通信模块的有效网络地址，或者从车辆管理服务器接收预设事件触发的通信模块的网络地址，其中的预设事件例如可以为通信模块的网络地址发生更新，以便用户终端从车辆管理服务器接收通信模块的更新的网络地址。
在一种可能的设计中，当用户终端周期性地从车辆管理服务器接收通信模块的网络地址时，若在超过一个周期的时长内未接收到新的有效网络地址，则用户终端将通信模块的网络地址设置为无效状态。
在一种可能的设计中，用户终端在发送第三远程控制命令之前，还可以获取通信模块的网络地址信息的状态，若处于有效状态，则根据有效的网络地址信息将唤醒命令和第三远程控制命令发送给通信模块，若处于无效状态，则将第一远程控制命令发送给车辆管理服务器。

图1为本申请实施例适用的一种可能的系统架构示意图，如图1所示的系统架构包括车辆管理服务器110、车辆120和用户终端130。其中，车辆120是指具有远程通信功能的车辆，车辆120的远程通信功能通常可以由设置在车辆120上的通信模块121实现，常见的通信模块121例如包括远程通信箱(telematics box，TBOX)。车辆管理服务器110可以是指单个服务器，也可以是指由多个服务器构成的服务器集群。在车联网领域中，该车辆管理服务器110具体可以是指云服务器，也称为云、云端、云端服务器、云端控制器或车联网服务器等。云服务器是对数据处理能力的设备或器件的统称，诸如可以包括主机或处理器等实体设备，也可以包括虚拟机或容器等虚拟设备，还可以包括芯片或集成电路。用户终端130是指向用户提供语音和/或数据连通性的设备。例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。目前，一些用户终端130的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等。

在介绍具体的实施例之前，先示例性介绍下本申请的下列实施例所涉及到的部分术语：
(1)车辆架构。
本申请实施例中的车辆可以具有以功能域为单位的集成化架构。即，车辆中的各个电子控制单元(electronic control unit，ECU)按照功能的不同划分至不同的功能域中，且每个功能域中还设置有对应的域控制器(domain control unit，DCU)，每个域控制器分别连接所在功能域中包含的各个电子控制单元，用于实现对所在功能域中原本分散的各个电子控制单元的集中管理和控制。其中，功能域也称为功能系统，常见的功能域可以包括但不限于：动力传动系统、底盘与安全系统、车身控制系统、信息娱乐系统或辅助驾驶系统等。
在以功能域为单位的集成化架构中，车辆中的车载网关作为整车交互的中心枢纽，与车辆中的各个域控制器互联，用于在各个域控制器之间安全地中转数据。当各个功能域分别采用不同的总线架构时，车载网关还担负着在不同总线架构之间协议转化的工作，以打破不同功能域之间对数据解析的隔阂。此外，车载网关还作为车辆与外部通信网络之间的沟通桥梁，经由车辆中的通信模块与车辆管理服务器建立安全高效的连接，用于根据通信模块从车辆管理服务器接收的数据完成对车内电子控制单元的升级、管理、维护和控制。
(2)长连接。
本申请实施例中的长连接是短连接的相对概念。短连接是指：通讯双方在每次需要发送数据时就建立一个连接，在数据发送完成后则断开连接，即每次所建立的连接只用于完成一次数据发送操作。长连接是指：通讯双方在建立连接并发送完数据后并不断开连接，而是继续保持连接，后续在需要继续发送数据时，直接在保持的连接上发送数据即可。在通讯双方保持长连接的情况下，通讯双方能在一个连接上连续发送多个数据包。且，在长连接保持期间，如果长时间没有发送数据包，则通常还需要通讯双方就当前的通讯链路进行检测，以及时发现通讯链路的故障。
(3)同时发送至少两个数据包。
本申请实施例中的同时发送至少两个数据包可以是指如下任一内容：采用至少两个线程并行发送至少两个数据包，或者采用单个线程连续发送至少两个数据包。即，只要至少两个数据包以可以忽略不计的时间间隔发出，即可认为至少两个数据包是同时发出的。
(4)用户密钥、车载密钥和车用交互密钥。
本申请实施例中的用户密钥是指用户终端与车辆管理服务器之间交互数据所使用的密钥。用户密钥可以是预先设置在用户终端和车辆管理服务器中的固定密钥，也可以是用户终端与车辆管理服务器通过周期协商得到的，还可以是按照用户终端和车辆管理服务器公知的某种预设算法生成的可变密钥，具体不作限定。
本申请实施例中的车载密钥是指通信模块与车辆管理服务器之间交互数据所使用的密钥。车载密钥可以是预先设置在通信模块和车辆管理服务器中的固定密钥，也可以是通信模块与车辆管理服务器通过周期协商得到的，还可以是按照通信模块和车辆管理服务器公知的某种预设算法生成的可变密钥，具体不作限定。

【实施例一】
图2示例性示出本申请实施例一提供的一种远程控制方法的流程示意图，该方法适用于车辆中的通信模块、车辆管理服务器、用户终端和车辆内的部件，其中，车辆中的通信模块、车辆管理服务器和用户终端例如可以为图1所示意出的车辆120中的通信模块121、车辆管理服务器110和用户终端130。如图2所示，该流程包括如下步骤：
步骤201，通信模块在处于支持远程唤醒功能的休眠状态时，接收唤醒命令和远程控制命令。
需要说明的是，本申请实施例中的通信模块可以具有如下三种状态：睡眠状态，也称为深睡眠状态，在该状态下通信模块支持本地唤醒但不支持远程唤醒，例如用户可以通过按压车内的启动按键来唤醒深睡眠状态下的通信模块；休眠状态，也称为浅休眠状态，在该状态下通信模块支持远程唤醒，例如用户可以通过手机发送远程命令来唤醒浅休眠状态下的通信模块；唤醒状态，在该状态下通信模块处于高功耗的工作模式，能够支持所有已配备的功能。无论是睡眠状态、休眠状态还是唤醒状态，通信模块都是通电的，只是睡眠状态的功耗要低于休眠状态的功耗，而休眠状态的功耗又低于唤醒状态的功耗。基于此，上述步骤201中，“支持远程唤醒功能的休眠状态”，即是指上述三种状态中的休眠状态。用户在不使用车辆时，可以选择睡眠车辆或休眠车辆：当选择睡眠车辆时，车辆中的通信模块会从工作状态切换至睡眠状态，通信模块无法接收外部设备发送的远程命令，但能通过车内部件指示唤醒；当选择休眠车辆时，车辆中的通信模块会从工作状态切换至休眠状 态，通信模块可以接收外部设备发送的远程命令，诸如车辆管理服务器或用户终端发送的唤醒命令或远程控制命令。
本申请实施例中，唤醒命令和远程控制命令可以由车辆管理服务器发送给通信模块(如图2中的步骤2001，具体实现过程请参照如下实施例二)，也可以由登录车辆管理服务器的用户终端发送给通信模块(如图2中的步骤2002，具体实现过程请参照如下实施例三)，还可以由车辆管理服务器和用户终端一起发送给通信模块。其中，由车辆管理服务器和用户终端一起发送的示例包括但不限于：车辆管理服务器在通信模块处于休眠状态时向通信模块发送唤醒命令，且用户终端在通信模块处于休眠状态时向通信模块发送远程控制命令，或者车辆管理服务器在通信模块处于休眠状态时向通信模块发送远程控制命令，且用户终端在通信模块处于休眠状态时向通信模块发送唤醒命令，或者车辆管理服务器在通信模块处于休眠状态时向通信模块发送唤醒命令和第二远程控制命令，用户终端在通信模块处于休眠状态时向通信模块发送第三远程控制命令，或者车辆管理服务器在通信模块处于休眠状态时向通信模块发送第一唤醒命令和第二远程控制命令，用户终端在通信模块处于休眠状态时向通信模块发送第二唤醒命令和第三远程控制命令等，此处不再一一列举。如此，通过在通信模块处于休眠状态时将远程控制命令发送给通信模块，而不是在唤醒后再发送远程控制命令，能节省等待唤醒及等待远程控制命令所引入的时延，有助于使通信模块在唤醒后直接使用远程控制命令执行远程控制，有效提高远程控制的及时性。
在一种可选地实施方式中，唤醒命令可以以短消息或IP数据包的形式发送，而远程控制命令可以以IP数据包的形式发送。也即是说，唤醒命令和远程控制命令可以以如下任一方式发送：唤醒命令和远程控制命令通过同一IP数据包发送给通信模块，以便通信模块同时获取到唤醒命令和远程控制命令；唤醒命令和远程控制命令通过连续的两个IP数据包发送给通信模块，以便通信模块户几乎无时差地获取到唤醒命令和远程控制命令；携带唤醒命令的短消息和携带远程控制命令的IP数据包同时发送给通信模块；携带唤醒命令的短消息或IP数据包先发送给通信模块，携带远程控制命令的IP数据包再发送给通信模块，且需要确保携带远程控制命令的IP数据包在携带唤醒命令的短消息或IP数据包成功唤醒通信模块之前发送给通信模块；携带唤醒命令的短消息、携带唤醒命令的IP数据包和携带远程控制命令的IP数据包同时发送给通信模块；携带唤醒命令的短消息先发送给通信模块，携带唤醒命令和远程控制命令的IP数据包再发送给通信模块；携带唤醒命令的IP数据包先发送给通信模块，携带唤醒命令的短消息和携带远程控制命令的IP数据包再发送给通信模块等。应理解，可能的发送方式有很多，只要能在通信模块处于休眠状态时将这两个命令发送给通信模块，都在本申请的保护范围内，本申请对此不再一一列举。
需要说明的是，在通过IP数据包的形式向通信模块发送命令时，需要获知通信模块的网络地址。在一种情况下，如果未来车辆中的通信模块如现阶段手机上的用户识别卡(subscriber identity module，SIM)卡一样存在固定联络的网络地址，诸如国际移动用户识别码(international mobile subscriber identity，IMSI)，或者主叫用户为呼叫移动通信网中用户所需拨号的号码(mobile subscriber international ISDN/PSTN number，MSISDN)，则车辆管理服务器或用户终端可以直接存储车辆中的通信模块的该网络地址，如此，后续在每次需要执行远程控制时，都可以通过该网络地址以IP数据包的形式将唤醒命令或远程控制命令发送给通信模块。在另一种情况下，如果车辆中的通信模块不具有固定联络的网络地址，则通信模块的网络地址可以是车辆管理服务器或用户终端向通信模块请求而得到的，也可 以是通信模块主动向车辆管理服务器或用户终端上报的，请求或上报的发生时机可以是在知晓需要执行远程控制之后，也可以是在知晓需要执行远程控制之前，具体不作限定。应理解，可能的实现方式还有很多，此处不再一一列举。
在一种可选地实施方式中，通信模块在接收唤醒命令和远程控制命令之前，还可以执行如下至少一项操作：
操作一，通信模块登录车辆管理服务器，如果登录成功，则通信模块与车辆管理服务器之间可以成功建立连接，如此，车辆管理服务器可以通过该连接向通信模块发送唤醒命令和远程控制命令，或者可以将该通信模块的相关信息发送给用户终端，以便于用户终端向该通信模块发送唤醒命令和远程控制命令。
操作二，通信模块周期性地将通信模块的有效网络地址发送给车辆管理服务器。该操作比较适用于通信模块频繁发生位置移动的场景，通过周期同步有效网络地址，有助于车辆管理服务器利用最新同步的网络地址发送携带唤醒命令或远程控制命令的IP数据包，或者能将最新同步的网络地址发送给用户终端，便于用户终端利用最新同步的网络地址发送携带唤醒命令或远程控制命令的IP数据包，有效提高发送唤醒命令和远程控制命令的成功概率。
操作三，通信模块将通信模块的更新的网络地址发送给车辆管理服务器。该操作比较适用于通信模块不常发生位置移动的场景，通过在网络地址变化时实时同步网络地址，车辆管理服务器能准确获知通信模块每次变化后的最新的网络地址，也能将通信模块每次变化后的最新的网络地址发送给用户终端，也能有助于提高以IP数据包发送唤醒命令或远程控制命令的成功概率。
操作四，通信模块周期性地向车辆管理服务器发送心跳数据包。该操作可以用于维持通信模块和车辆管理服务器的长连接，在长连接下，如果车辆管理服务器在一个周期内接收到心跳数据包，则确定与通信模块之间的长连接还存在，车辆管理服务器可以直接通过该长连接获取通信模块的网络地址，按照该网络地址向通信模块发送唤醒命令或远程控制命令，或者将获取的网络地址发送给用户终端，以便用户终端按照该网络地址向通信模块发送唤醒命令或远程控制命令，而不必再重新建立连接。如果车辆管理服务器在一个周期内未接收到心跳数据包，则确定与通信模块之间的长连接已断开，车辆管理服务器需要先和通信模块建立连接，再通过新建立的连接发送唤醒命令或远程控制命令。其中，心跳数据包的包头中可以携带有车辆管理服务器的网络地址，该网络地址是指能够用于与车辆管理服务器进行网络通信的地址信息，例如可以包括车辆管理服务器的IP地址和端口号，而至于心跳数据包的包体中携带的内容则不作具体限定，例如可以是一个默认的校验值，也可以是一个空包，还可以是通信模块的有效网络地址。
操作五，通信模块向车辆管理服务器发送更新后的车载密钥，该车载密钥可以用于通信模块和车辆管理服务器的后续通信，如车辆管理服务器能使用最新更新的车载密钥加密唤醒命令和远程控制命令后再发送给通信模块，以提高远程控制的安全性。
操作六，通信模块周期性地与车辆管理服务器进行鉴权认证。该鉴权认证既可以用于通信模块确保车辆管理服务器的合法性，也可以用于车辆管理服务器确保通信模块的合法性，车辆管理服务器可以只向鉴权认证通过的通信模块发送唤醒命令和远程控制命令，通信模块也可以只接收并执行鉴权认证通过的车辆管理服务器发送的唤醒命令和远程控制命令，尽可能地保证远程控制的安全性。
需要说明的是，上述操作一至操作六还可以相互组合以得到新的操作，示例来说：
当组合操作一和操作二时，通信模块可以先登录车辆管理服务器，并在登录成功后周期性地向车辆管理服务器发送自己的有效网络地址，以便车辆管理服务器能利用之前登录的通信模块在最新一次发送的有效网络地址向之前登录的通信模块发送携带唤醒命令或远程控制命令的IP数据包。
当组合操作一和操作三时，通信模块可以先登录车辆管理服务器，并在登录成功后实时监控自己的网络地址，一旦发现网络地址发生变化则将变化的网络地址发送给车辆管理服务器，以便车辆管理服务器能利用之前登录的通信模块变化后的最新网络地址向之前登录的通信模块发送携带唤醒命令或远程控制命令的IP数据包。
当组合操作一、操作二和操作三时，通信模块可以先登录车辆管理服务器，在登录成功后，一方面可以周期性地向车辆管理服务器发送自己的有效网络地址，另一方面还可以监控自己的网络地址，一旦发现网络地址发生变化，则也将变化的网络地址发送给车辆管理服务器，并重启发送周期。该方式能进一步保证车辆管理服务器获知最准确的网络地址，有助于提高发送携带唤醒命令或远程控制命令的成功概率。
当组合操作二和操作四时，通信模块可以将有效网络地址放在心跳数据包中，周期性地将心跳数据包发送给车辆管理服务器，以便车辆管理服务器通过解析心跳数据包获得有效网络地址。该组合能将周期同步有效网络地址的操作放在长连接的流程中实现，而可以不再额外浪费资源同步有效网络地址，有助于节省通信模块的计算资源。
当组合操作三和操作四时，通信模块可以针对于一个心跳周期间发生变化的网络地址生成一个心跳数据包后发送给车辆管理服务器，并可以以当前的心跳数据包为基准重启心跳周期的计时，该组合能将实时变化的网络地址应用在维持长连接的心跳数据包中，有助于提高对维持长连接和同步网络地址的灵活管理。
当组合操作二、操作三和操作四时，通信模块除了可以在每个心跳周期将发送的心跳数据包中添加自己的有效网络地址以外，还可以将一个心跳周期间发生变化的网络地址单独发送给车辆管理服务器，或者针对于一个周期间发生变化的网络地址生成一个新的心跳数据包后发送给车辆管理服务器，并重启心跳周期的计时。
当组合操作一和操作四时，通信模块可以先登录车辆管理服务器，并在登录成功后周期性地向车辆管理服务器发送心跳数据包，也即是，在登录成功后开始维持与车辆管理服务器的长连接，以便依赖维持的长连接发送唤醒命令和远程控制命令。
当组合操作一和操作四、以及操作二和/或操作三时，通信模块可以先登录车辆管理服务器，并在登录成功后周期性地向车辆管理服务器发送携带有效网络地址或变化的网络地址的心跳数据包，以便车辆管理服务器解析心跳数据包获得有效网络地址或变化的网络地址。
当组合操作一和操作五时，通信模块可以先登录车辆管理服务器，在登录成功后周期或实时向车辆管理服务器发送最新更新后的车载密钥，以便车辆管理服务器和通信模块在登录状态下加密待同步的消息，提高消息传输的安全性。
当组合操作一、操作五、以及操作二和/操作三时，通信模块可以先登录车辆管理服务器，在登录成功后周期或实时向车辆管理服务器发送最新更新后的车载密钥，并使用最新更新后的车载密钥加密有效网络地址或变化的网络地址，向车辆管理服务器发送加密后的信息，以便车辆管理服务器也能使用最新更新后的车载密钥解密得到有效网络地址或变化 的网络地址，利用有效网络地址或变化的网络地址，向通信模块发送最新更新后的车载密钥加密的唤醒命令和远程控制命令。该组合相当于在维持长连接的过程中周期更新车载密钥，即使通信模块与车辆管理服务器长时间处于连接状态，通过隔一段时间就更新一次车载密钥，也能降低非法设备获取最新车载密钥的概率，提高通信模块识别历史车载密钥加密的非法消息的准确性，阻止非法设备通过侵入该长连接对通信模块进行的非法控制，有效提高长连接的安全性。
当组合操作一、操作四、操作五、以及操作二和/操作三时，通信模块可以先登录车辆管理服务器，在登录成功后周期或实时向车辆管理服务器发送最新更新后的车载密钥，并使用最新更新后的车载密钥加密有效网络地址或变化的网络地址，向车辆管理服务器发送携带加密后的网络地址的心跳数据包，以便车辆管理服务器通过解析心跳数据包获得加密的有效网络地址或变化的网络地址后，使用最新更新后的车载密钥解密得到有效网络地址或变化的网络地址，并利用有效网络地址或变化的网络地址，向通信模块发送最新更新后的车载密钥加密的唤醒命令和远程控制命令。
当组合操作一和操作六时，通信模块可以先登录车辆管理服务器，在登录成功后周期性地与车辆管理服务器进行鉴权认证，该组合能对登录状态下的通信模块和车辆管理服务器周期性地进行安全认证，有助于保证两者登录状态的可信度。
当组合操作一、操作五和操作六时，通信模块可以先登录车辆管理服务器，在登录成功后周期性地与车辆管理服务器进行鉴权认证，并在鉴权认证的过程中更新车载密钥。如此，通过将协商车载密钥的操作放在周期鉴权认证的过程中执行，能节省通信模块的资源。
当组合操作一、操作六、以及操作二和/操作三时，通信模块可以先登录车辆管理服务器，在登录成功后，周期性地与车辆管理服务器进行鉴权认证，在鉴权认证通过的情况下，周期性地向车辆管理服务器发送有效网络地址或变化的网络地址，以便车辆管理服务器获得安全的有效网络地址或变化的网络地址。
当组合操作一、操作四、操作五、操作六、以及操作二和/操作三时，通信模块可以先登录车辆管理服务器，在登录成功后，周期性地与车辆管理服务器进行鉴权认证，并在鉴权认证的过程中同步更新的车载密钥，在鉴权通过的情况下，使用最新更新后的车载密钥加密有效网络地址或变化的网络地址，向车辆管理服务器发送携带加密后的网络地址的心跳数据包，以便车辆管理服务器通过解析心跳数据包获得加密的有效网络地址或变化的网络地址后，使用最新更新后的车载密钥解密得到有效网络地址或变化的网络地址，并利用有效网络地址或变化的网络地址，向通信模块发送最新更新后的车载密钥加密的唤醒命令和远程控制命令。
应理解，上述内容只是示例性介绍几种可能的组合，但这并不是全部组合，凡是能够组合上述操作一至操作六中的一个或多个而得到的新操作都在本申请的保护范围内，本申请对此不再一一列举。
步骤202，通信模块根据唤醒命令，使通信模块进入唤醒状态。
在上述步骤202中，通信模块可以先根据唤醒命令唤醒自己内部的其它程序，以使通信模块切换到正常工作状态，且通信模块还可以唤醒车辆内的其它部件，其它部件可以是远程控制命令对应的待控制的部件，也可以是车辆内的全部部件。以车辆内的全部部件为例，唤醒过程具体可以包括：通信模块先将携带唤醒命令的认证消息发送给休眠状态的车载网关，车载网关被通信模块的认证消息所触发而切换至工作状态；之后，车载网关判断 确定该认证消息是否合法(例如确定通信模块是否使用合法的车内密钥加密认证消息)，若合法，则根据车内部件交互所使用的控制器局域网络(controller area network，CAN)消息格式，将唤醒命令转化为CAN消息后发送给车内的各个域控制器，由各个域控制器分别唤醒各自域内所管理的ECU。当然，发送给每个域控制器的CAN消息也需要使用每个域控制器所对应的车内密钥进行加密，任一域控制器所对应的车内密钥通常会在车辆出厂前预置在车辆内部，也可以在车辆出厂后通过该域控制器与其域内的ECU周期性地同步进行更新。
步骤203，通信模块根据远程控制命令，向车辆内的部件发送控制消息。
在上述步骤203中，通信模块在确定车辆内的其它部件唤醒完成后(例如接收到车载网关返回的唤醒成功响应)，通信模块可以根据远程控制命令生成控制消息，并将控制消息发送给车载网关，由车载网关按照CAN消息格式将控制消息转化为CAN消息后发送给待控制的ECU所在的域控制器，以通过该域控制器向待控制的ECU发送该控制消息。
应理解，上述步骤202和步骤203只是以通信模块分别发送唤醒命令和远程控制命令为例进行介绍。在另一种方案中，通信模块也可以生成同时携带唤醒命令和远程控制命令对应的控制消息的认证消息给车载网关，由车载网关认证合法后，根据唤醒命令和控制消息唤醒各个ECU后直接控制待控制的ECU完成远程控制。
步骤204，车辆内的部件根据控制消息启动该部件或者执行远程控制命令指示的操作。
在上述步骤204中，待控制的ECU接收到控制消息后，可以执行启动或远程控制命令对应的控制操作，这些操作包括但不限于：启动空调运行(有些情况下还需要同时启动发动机驱动空调运转)、远程解锁/上锁车门、远程寻车(如远程控制车辆自动驾驶至用户所在位置，或远程闪灯和鸣笛以便用户找到车辆等)或远程打开/闭锁车窗等。
示例性地，当域控制器确定待控制的ECU成功完成远程控制时，域控制器还可以依次经由车载网关和通信模块向车辆管理服务器返回控制成功响应，由车辆管理服务器再返回给用户终端，或者依次经由车载网关和通信模块向用户终端返回控制成功响应，以通过用户终端显示给用户。
在上述实施例一中，通过在车辆的通信模块处于休眠状态时将远程控制命令发送给通信模块，有助于通信模块在唤醒车内部件后立即执行远程控制，有效避免等待车内部件唤醒响应后再发送远程控制命令所引入的时延，有助于提高远程控制的及时性。
下面基于实施例二和实施例三，进一步介绍本申请中远程控制方法的具体实现。
【实施例二】
图3示例性示出本申请实施例二提供的远程控制方法的流程示意图，该方法适用于车辆管理服务器、车辆中的通信模块和用户终端，例如图1所示意出的车辆管理服务器110、车辆120中的通信模块121和用户终端130。如图3所示，该流程包括如下步骤：
步骤301，通信模块登录车辆管理服务器。
示例性的，登录过程具体可以参照如下步骤a～步骤c：
步骤a，通信模块在初次登录车辆管理服务器时，向车辆管理服务器发送登录请求，登录请求中携带待认证信息和通信模块的网络地址。其中，待认证信息可以包括通信协议的版本信息，还可以包括车辆识别码(vehicle identification number，VIN)、或其它能够指示车辆或通信模块的标志性信息。待认证信息通常在车辆出厂之前预置在车辆的通信模块中。
步骤b，车辆管理服务器根据预设的认证算法对登录请求中的待认证信息进行验证，若验证通过，则确定登录请求合法，车辆管理服务器允许通信模块登录，并存储通信模块的网络地址，根据该网络地址向通信模块返回登录成功响应。其中，预设的认证算法可以由本领域技术人员根据经验进行设置，并可预先同步给通信模块，以便通信模块也能按照该预设的认证算法设置待认证信息。
示例性的，通信模块和车辆管理服务器可以通过双向认证方法完成登录。具体地说，通信模块在初次登录车辆管理服务器时向车辆管理服务器发起登录请求，而车辆管理服务器接收到该登录请求后，将车辆管理服务器的公钥证书发送给通信模块，通信模块读取车辆管理服务器的公钥证书获得车辆管理服务器的公钥，并将通信模块的公钥证书发送给车辆管理服务器，车辆管理服务器使用根证书解密通信模块的公钥证书获得通信模块的公钥。之后，通信模块向车辆管理服务器发送自己支持的加密方案，车辆管理服务器根据自身支持的加密方案和通信模块支持的加密方案，选择一个双方都能支持的加密方案，使用通信模块的公钥加密后发送给通信模块。通信模块使用自己的私钥解密接收到的加密方案后，生成一个随机数，将该随机数作为后续与车辆管理服务器通信的车载密钥(即初次协商得到的车载密钥)，使用车辆管理服务器的公钥加密该随机数并发送给车辆管理服务器。车辆管理服务器使用自己的私钥解密获得随机数，将该随机数作为后续与通信模块通信的车载密钥。如此，车辆管理服务器和通信模块在后续的通信过程中使用双方协商的车载密钥进行通信。其中，车辆管理服务器的公钥证书、车辆管理服务器的私钥、根证书以及车辆管理服务器支持的加密方案可以由本领域技术人员提前预置在车辆管理服务器中，通信模块的公钥证书、通信模块的私钥以及通信模块支持的加密方案可以在车辆出厂之前由研发人员提前预置在通信模块中。
步骤c，通信模块在接收到车辆管理服务器返回的登录成功响应后，确定通信模块成功登录车辆管理服务器，也即是，通信模块与车辆管理服务器之间成功建立连接，通信模块可以通过该连接访问车辆管理服务器中的资源，例如语音服务资源、地图导航资源或联网查询资源等。
步骤302，通信模块与车辆管理服务器按照第一预设周期协商获得更新的车载密钥。
在一种可选地实施方式中，车载密钥可以通过通信模块按照第一预设周期主动向车辆管理服务器申请协商的方式更新。即，通信模块中维持第一计时器，第一计时器的计时时长为一个第一预设周期的周期时长，通信模块在成功登录车辆管理服务器后，即可启动第一计时器，每当第一计时器计时到对应的计时时长后，通信模块即可向车辆管理服务器发送密钥更新请求，并重启第一计时器。其中，密钥更新请求中也可以携带通信模块的网络地址，以便通信模块和车辆管理服务器在协商车载密钥的过程中同步通信模块的网络地址，进一步提高车辆管理服务器中存储的通信模块的网络地址的准确性。密钥更新请求还可以使用上一次协商出的车载密钥进行加密。如此，车辆管理服务器在接收到密钥更新请求后，可以先使用上一次协商出的车载密钥解密得到明文的密钥更新请求，再验证该密钥更新请求中携带的通信模块的身份信息是否合法。若合法，则车辆管理服务器可以为通信模块设置一个新的车载密钥，并使用上一次协商出的车载密钥加密新的车载密钥后，根据本地存储的通信模块的网络地址(参照如下步骤303)，将加密后的新的车载密钥发送给通信模块，以完成车载密钥的更新操作。其中，新的车载密钥可以是车辆管理服务器从预设的车载密钥集合中随机选取或顺序选取的，也可以是按照预设算法生成的，还可以是根据密钥更新 请求中携带的一些信息变形得到的，具体不作限定。
需要说明的是，通信模块可以按照第一预设周期不断申请协商车载密钥，而不考虑上次申请是否成功。如此，即使通信模块与车辆管理服务器之间协商车载密钥的操作出现问题导致数据交互中断(例如车辆管理服务器生成了新的车载密钥，但并未成功下发给通信模块，导致通信模块使用旧的车载密钥而车辆管理服务器使用新的车载密钥，两者虽然能接收到数据，但无法解密对方的数据完成数据交互)，也能通过通信模块后续的主动申请协商，完成后续生成的新的车载密钥的协商，恢复两者之间的正常数据交互。
步骤303，通信模块按照第二预设周期向车辆管理服务器发送有效网络地址。
本申请实施例中，在通信模块初次登录车辆管理服务器后，车辆管理服务器即可在本地存储通信模块的网络地址，并可以在后续与通信模块的交互过程中周期或实时更新该网络地址。如此，当需要执行远程控制时，车辆管理服务器直接查询本地即可获得通信模块的网络地址。其中，通信模块的网络地址可以以通信模块的标识与网络地址的对应关系的形式存储在车辆管理服务器中，该对应关系可以表现为表格、图片或数据栈中的任意一项或任意多项。如此，即使车辆管理服务器同时与多个通信模块建立连接，车辆管理服务器也能根据该对应关系准确实现与任一通信模块的通信。
在一种可选地实施方式中，通信模块的有效网络地址可以通过通信模块按照第二预设周期主动向车辆管理服务器上报心跳数据包的方式实现更新。即，通信模块中维持第二计时器，第二计时器的计时时长为第二预设时长，通信模块在成功登录车辆管理服务器后，即可启动第二计时器，每当第二计时器计时到对应的计时时长后，通信模块即可向车辆管理服务器发送心跳数据包，并重启第二计时器。其中，心跳数据包中可以携带车辆管理服务器的网络地址，用于将心跳数据包发送给车辆管理服务器，以及携带通信模块的有效网络地址。如此，通过通信模块在登录车辆管理服务后周期发送携带有效网络地址的心跳数据包给车辆管理服务器，不仅能保持通信模块与车辆管理服务器之间的长连接，还能使车辆管理服务器及时获知到通信模块当前的有效网络地址。该方式相当于将同步有效网络地址的操作融合在保持长连接的流程中一起实现，可以无需再额外设置周期同步有效网络地址的操作，有助于节省车辆管理服务器与通信模块之间的通信开销。
需要说明的是，本申请实施例中，长连接的保持可以通过通信模块主动发起心跳数据包的方式来实现，至于该心跳数据包是否发送成功则不关心。如此，即使长连接在某一时刻出现问题(例如通信模块的网络地址发生了变化，但变化的网络地址并未成功通知给车辆管理服务器，导致车辆管理服务器按照旧的网络地址所发送的消息无法通知给通信模块)，通信模块与车辆管理服务器之间的长连接也只是中断而不结束，只要问题解决了，车辆管理服务器就能根据通信模块在下一计时周期发送的心跳数据包中携带的有效网络地址，重新恢复与通信模块的长连接，以继续与通信模块的通信。
示例性的，通信模块在与车辆管理服务器建立连接后，还可以执行如下步骤304：
步骤304，通信模块实时地向车辆管理服务器发送变化的网络地址。
在上述步骤304中，通信模块还可以监测自己的网络地址，一旦发现自己的网络地址发生变化，则实时地将变化的网络地址上报给车辆管理服务器。对应的，车辆管理服务器在接收到通信模块发送的变化的网络地址后，也可以使用变化的网络地址更新本地存储的通信模块的网络地址。如此，即使通信模块在两个心跳数据包的发送间隔内切换了网络地址，车辆管理服务器也能及时获取到最新的网络地址，有助于提高车辆管理服务器本地存 储的网络地址的准确性。
需要说明的是，变化的网络地址可以是按照单独的消息格式发送给车辆管理服务器，也可以是携带在心跳数据包中发送给车辆管理服务器，具体不作限定。当有效网络地址和变化的网络地址都携带在心跳数据包中发送给车辆管理服务器时，通信模块可以以最新发送的心跳数据包为基准重启第二计时器。例如，通信模块在某一时刻发送携带有效网络地址的心跳数据包后启动第二计时器，如果在还没计时到第二预设时长之前，又实时发送了携带变化的网络地址的心跳数据包，则通信模块可以再重启第二计时器，以避免短时间内重复发送相同的网络地址，有效节省通信模块的通信损耗。
应理解，本申请实施例中，通信模块可以以明文的形式直接将有效网络地址或变化的网络地址发送给车辆管理服务器，也可以使用最近协商的车载密钥加密后以密文的形式将有效网络地址或变化的网络地址发送给车辆管理服务器，具体不作限定。
步骤305，车辆管理服务器判断一个第二预设周期内是否接收到通信模块发送的网络地址，若是，则执行步骤306，若否，则执行步骤307。
示例性的，车辆管理服务器中还可以维持第三计时器，第三计时器的计时时长也为第二预设时长。车辆管理服务器每接收到通信模块发送的一个网络地址(可能是有效网络地址或变化的网络地址)，都可以启动第三计时器。在计时到第三计时器的计时时长之前，如果车辆管理服务器接收到了新的有效网络地址或变化的网络地址，则确定第二预设周期内接收到通信模块发送的网络地址。在计时到第三计时器的计时时长时，如果车辆管理服务器还未接收到新的有效网络地址或变化的网络地址，则确定第二预设周期内未接收到通信模块发送的网络地址。例如，车辆管理服务器在某一时刻接收到有效网络地址后启动第三计时器，如果在还没计时到第二预设时长之前，又接收到了变化的网络地址，则车辆管理服务器可以执行步骤306并重启第三计时器，如果直至重启后的第三计时器计时到第二预设时长且未收到新的有效网络地址或变化的网络地址时，确定车辆管理服务器可以执行步骤307并重启第三计时器。
需要说明的是，第二预设周期可以是车辆管理服务器设置并下发给通信模块的，也可以是通信模块设置并同步给车辆管理服务器的，还可以是本领域技术人员设置在车辆管理服务器和通信模块中的，具体不作限定。
步骤306，车辆管理服务器将本地存储的通信模块的网络地址更新为接收到的网络地址。
在上述步骤306中，当车辆管理服务器能在一个第二预设周期内接收到通信模块发送的有效网络地址或变化的网络地址时，说明车辆管理服务器与通信模块在当前第二预设周期内的网络状态较好，该网络地址大概率即为通信模块当前的网络地址。在这种情况下，车辆管理服务器可以使用所接收到的网络地址更新本地存储的通信模块的网络地址，例如将本地存储的网络地址直接替换为接收到的网络地址，或者在本地添加接收到的网络地址后，为原网络地址打上失效标签，且为新添加的网络地址打上生效标签，或者在本地添加接收到的网络地址后标注接收时间戳等。其中，接收到的网络地址可能与原网络地址不同(如车辆移动到另一区域)，也可能与原网络地址相同(如车辆仍在原区域)，不作限定。
在一种可选地实施方式中，车辆管理服务器在成功更新网络地址后，还可以使用更新后的网络地址向通信模块返回更新成功响应。对应的，通信模块每发送一个网络地址后，还可以等待车辆管理服务器返回更新成功响应。如果在预设的等待时长(远小于第二预设 时长)内一直未接收到车辆管理服务器返回的更新成功响应，则说明本次网络地址发送失败，通信模块可以重发当前的有效网络地址。如果通信模块在预设次数内的重发操作中接收到了更新成功响应，说明上次发送失败的现象很可能是由于一些偶然因素所导致的，例如上次发送中意外丢包等。在这种情况下，通过通信模块的上述重发操作，能及时恢复由于这些偶然因素所导致的长连接中断。如果在预设次数内的重发操作中一直未接收到更新成功响应，说明上述发送失败的现象很可能是由于通信链路异常导致的，例如通信模块当前处于一个网络覆盖较弱的区域。在这种情况下，通信模块可以结束重发，并可以等待下一个第二预设周期来临后再发送携带网络地址的心跳数据包，以便等通信模块重新移动至网络覆盖较好的区域之后再恢复之前中断的长连接，节省不必要的通信消耗。此外，如果多个第一预设周期都没有接收到更新成功响应，说明通信模块和车辆管理服务器之间的通信链路可能存在某种不可自动恢复的故障，例如通信模块或车辆管理服务器的硬件通信模块损坏。在这种情况下，通信模块还可以生成告警消息并发送给运维节点，以及时修复与车辆管理服务器之间的通信故障。
步骤307，车辆管理服务器失效本地存储的通信模块的网络地址。
在上述步骤307中，当车辆管理服务器无法在一个第二预设周期内接收通信模块发送的携带网络地址的心跳数据包时，说明在当前第二预设周期内车辆管理服务器与通信模块的通信链路出现问题，该问题可能是由于车辆管理服务器或通信模块中的硬件通信模块故障、或网络状态不好等因素造成的，车辆管理服务器在当前时段内大概率无法再通过网络方式与通信模块交互数据。在这种情况下，车辆管理服务器可以直接失效本地存储的通信模块的网络地址，以暂时中断车辆管理服务器与通信模块之间的网络通信方式。之后，车辆管理服务器进入等待阶段，直至某个时刻重新接收到通信模块发送的携带网络地址的心跳数据包后，车辆管理服务器可以重新生效本地存储的网络地址，并将该网络地址更新为接收到的新的网络地址，以恢复车辆管理服务器与通信模块之间的网络通信方式。
步骤308，用户终端登录车辆管理服务器。
步骤309，用户终端向车辆管理服务器发送远程控制命令(即第一远程控制命令)。
示例性的，用户终端在确定存在远程控制需求时，可以先使用用户密钥加密远程控制命令，再将加密后的远程控制命令发送给车辆管理服务器。通过加密用户终端的远程控制命令，不仅能降低远程控制命令在远程传输过程中被篡改的风险，还能使车辆管理服务器准确识别出非法终端发送的非法远程控制命令，有效提高远程控制车辆的安全性。
本申请实施例中，用户终端与车辆管理服务器的交互可以通过用户终端上的目标应用程序(application，APP)来实现。其中，目标APP可以是专门开发以用于实现远程控制功能的APP，也可以是用户终端中用于其它应用功能的APP，例如智慧车辆。当目标APP为用户终端中用于其它应用功能的APP时，本申请中的远程控制方法的程序可以预置在新版本的目标APP中，如此，用户只要执行升级目标APP的操作，即可使目标APP也具有远程控制车辆的功能。
下面示例性介绍下基于用户终端上的目标APP向车辆管理服务器发送远程控制命令的界面操作流程：
图4中(a)示例性示出本申请实施例提供的一种用户终端的界面示意图，如图4中(a)所示，用户终端的界面上可以设置有多个应用程序，例如日历、时钟、通话记录、信息、设置、图库、一键锁屏、视频电话和目标APP(即图4中(a)所示意出的车控APP401)。 在用户需要执行远程控制命令时，用户可以点击目标APP，然后注册并登录(若用户之前注册过用户账号，则用户可以直接登录)，在车辆管理服务器验证用户账号合法后，进入目标APP的主界面。其中，用户账号一般可以包括用户名和密码，密码可以为用户设置的固定密码，也可以为短信校验码、人脸信息、虹膜信息或指纹信息等，不作限定。
图4中(b)示例性示出本申请实施例提供的一种目标APP中的主界面示意图，如图4中(b)所示，目标APP的主界面中存在多个功能按键，例如添加车辆按键、选择车辆按键、删除车辆按键等。当用户需要对之前已经在目标APP上添加过的某辆车进行远程控制时，用户可以直接点击主界面上的选择车辆按键，进入车辆选择界面。当用户需要对之前未在目标APP上添加过的某辆车进行远程控制时，用户可以先点击主界面上的添加车辆按键切换到添加车辆界面，并在该界面上填写待添加的车辆信息(如车辆的VIN)，在通过车辆管理服务器绑定待添加的车辆和用户账号后，再返回主界面中点击选择车辆按键以进入车辆选择界面，此时车辆选择界面中会显示有用户刚刚添加的车辆信息。
图4中(c)示例性示出本申请实施例提供的一种目标APP中的车辆选择界面示意图，如图4中(c)所示，车辆选择界面上可以显示有至少一台车辆的相关信息，相关信息可以包括车辆的图片、品牌或车系等属性信息，还可以包括油量或使用年限等性能信息。用户可以在车辆选择界面上选中想要执行远程控制的车辆，以进入远程控制界面。
图4中(d)示例性示出本申请实施例提供的一种目标APP中的远程控制界面示意图，如图4中(d)所示，远程控制界面上显示有一个或多个远程控制命令，例如可以包括如图4中(d)所示意的启动空调命令、闪灯鸣笛命令、开窗透气命令和座椅加热命令，还可以包括解锁车门命令、开启后备箱命令、启动引擎命令或空气净化命令等其它远程控制命令。用户可以在远程控制界面上点击想要执行的远程控制命令。当目标APP检测到该点击操作后，目标APP可以根据被点击的远程控制命令生成远程控制请求并发生给车辆管理服务器，之后根据车辆管理服务器返回的响应内容切换至命令执行界面。
图4中(e)和图4中(f)示例性示出本申请实施例提供的两种目标APP中的命令执行界面示意图。如图4中(e)所示，在远程控制命令执行成功之前，该界面上可以显示有“正在执行远程控制，请耐心等待……”的文字信息，在远程控制命令执行成功后，即，目标APP接收到车辆管理服务器返回的执行成功响应后，该界面上可以显示有“远程控制已完成”的文字信息。如图4中(f)所示，目标APP不仅能向用户显示是否执行完成，还能通过圆圈加黑的形式显示执行进度。应理解，图4中(e)和图4中(f)只是两种示例性的说明，只要能够通过界面显示的方式提示用户当前是否执行完成的方案都在本申请的保护范围内，本申请对此不再一一列举。
步骤310，车辆管理服务器判断本地存储的通信模块的网络地址是否有效，若有效，则执行步骤311，若无效，则执行步骤313。
步骤311，车辆管理服务器根据本地存储的通信模块的网络地址、唤醒命令和远程控制命令，生成第一唤醒/远程控制IP数据包，使用最新协商的车载密钥加密第一唤醒/远程控制IP数据包，得到加密后的第一唤醒/远程控制IP数据包。
在上述步骤311中，第一唤醒/远程控制IP数据包可以包括唤醒IP数据包和远程控制IP数据包，也可以包括唤醒加远程控制IP数据包。其中，唤醒数据包是指根据通信模块的网络地址和唤醒命令生成的用于指示车辆唤醒的一个IP数据包。远程控制IP数据包是指根据通信模块的网络地址和远程控制命令生成的用于指示部件启动或执行第一操作的 一个IP数据包。唤醒加远程控制IP数据包是指根据通信模块的网络地址、唤醒命令和远程控制命令生成的用于指示车辆唤醒后指示部件启动或执行第一操作的一个IP数据包。如此，通过车辆管理服务器以网络方式实时地将唤醒命令和远程控制命令发送给通信模块，相比于短消息发送命令的方式来说，可以避免短消息经运营商侧的短消息中心转发所引入的短消息转发时延，有效提高唤醒车辆及远程控制车辆的时效性。
在一种可选地实施方式中，在生成携带远程控制命令的IP数据包(如远程控制IP数据包或唤醒加远程控制IP数据包)后，车辆管理服务器还可以先使用车载密钥加密该IP数据包，再将加密后的该IP数据包发送给通信模块。其中，车辆管理服务器可以使用车载密钥加密IP数据包中除通信模块的网络地址以外的信息，以保证加密后的IP数据包仍能发送给通信模块，例如，可以加密除通信模块的网络地址以外的其它全部信息，以有效保证全部数据传输的安全性，或者，也可以只加密远程控制命令而不加密其它信息，以降低车辆管理服务器的工作压力。通过加密车辆管理服务器与通信模块之间的用于远程控制车辆的IP数据包，不仅能降低远程控制命令在传输过程中被篡改的风险，还能使通信模块准确识别出非法车辆管理服务器或非法终端发送的非法控制命令，有效提高远程控制车辆的安全性。
应理解，携带唤醒命令的IP数据包(如唤醒IP数据包)也可以先使用车载密钥加密后再发送，以提高通信模块识别非法唤醒命令的准确性，节省不必要的电量浪费，提高车辆的续航能力。
步骤312，车辆管理服务器同时将加密后的第一唤醒/远程控制IP数据包和唤醒短消息发送给通信模块。
在上述步骤312中，第一唤醒/远程控制IP数据包会以网络方式发送给通信模块，而唤醒短消息则会以短信形式经运营商侧的短消息中心转发给通信模块。
应理解，车辆管理服务器也可以只发送第一唤醒/远程控制IP数据包而不发送唤醒短消息，具体不作限定。
步骤313，车辆管理服务器将唤醒短消息发送给通信模块。
在上述步骤313中，当车辆管理服务器中存储的通信模块的网络地址无效时，意味着，车辆管理服务器与通信模块之间的网络链路暂时中断，车辆管理服务器当前无法通过网络方式指示车辆唤醒。因此，车辆管理服务器可以发送唤醒短消息而不发送第一唤醒/远程控制IP数据包，如此，既可以节省车辆管理服务器与通信模块之间不必要的通信开销，又能以唤醒短消息的常规形式成功唤醒车辆。
步骤314，通信模块判断最先接收到的信息为加密后的第一唤醒/远程控制IP数据包还是唤醒短消息：
当先接收到加密后的第一唤醒/远程控制IP数据包时，执行步骤315；
当先接收到唤醒短消息时，执行步骤316。
在上述步骤314中，理论上来说，在网络状态较好的情况下，加密后的第一唤醒/远程控制IP数据包可能仅需要大概500ms(毫秒)的时间就能成功发送给通信模块，而唤醒短消息则需要至少15s(秒)的时间才能被发送给通信模块，因此，通信模块大概率会先接收到加密后的第一唤醒/远程控制IP数据包。当然，在网络状态不好或发生其它偶然事件的情况下，加密后的第一唤醒/远程控制IP数据包也可能在经过15秒的时间还没发送到通信模块，因此，通信模块也可能会先接收到唤醒短消息。
步骤315，通信模块使用最近协商的车载密钥对加密后的第一唤醒/远程控制IP数据包进行解密，得到唤醒命令和远程控制命令(即第二远程控制命令)，根据唤醒命令和远程控制命令唤醒车辆后直接执行远程控制。
在上述步骤315中，在通信模块先接收到加密后的第一唤醒/远程控制IP数据包的情况下，通信模块可以直接丢弃后续接收到的唤醒短消息，而不需要再解析唤醒短消息，以节省计算资源。
步骤316，通信模块根据唤醒短消息唤醒车辆。
在上述步骤316中，在通信模块先接收到唤醒短消息的情况下，意味着，通信模块与车辆管理服务器之间的网络链路存在问题，该问题可能是由于车辆管理服务器与通信模块之间的网络地址更新错误导致的，也可能是由于车辆管理服务器与通信模块之间的密钥协商错误导致的。在这种情况下，车辆管理服务器中存储的通信模块的网络地址和通信模块真实的网络地址信可能不同，车辆管理服务器中存储的车载密钥和通信模块中存储的车载密钥也可能不同。因此，通信模块在唤醒车辆后，还可以重新与车辆管理服务器进行鉴权认证，即，重新与车辆管理服务器协商更新车载密钥，且重新向车辆管理服务器发送当前的网络地址，以便车辆管理服务器和通信模块能协商出相同且准确的车载密钥和网络地址。之后，车辆管理服务器可以基于准确的车载密钥和网络地址向通信模块发送远程控制命令，而通信模块也可以基于准确的车载密钥和网络地址执行远程控制命令，以完成远程控制。
示例性的，通信模块在唤醒车辆后，从上述常规流程中的重新鉴权开始直至获取到远程控制命令的期间中，如果通信模块又接收到了加密后的第一唤醒/远程控制IP数据包，意味着当前的网络链路重新恢复正常，通信模块可以不再等待常规鉴权完成后才启动远程控制，而是可以直接终止常规流程，并根据从加密后的第一唤醒/远程控制IP数据包中解析出的远程控制命令直接启动远程控制，以尽快完成远程控制。
在上述实施例二中，由于短消息的无线覆盖效果优于数据业务的网络覆盖效果，因此，通过同时以网络形式和短信形式向通信模块发送唤醒命令，既能在网络较好的情况下快速地将唤醒命令传递给通信模块，提高唤醒车辆的效率，又能在网络不好的情况下通过网络覆盖效果更优的唤醒短消息成功唤醒车辆。相比于先以网络形式发送唤醒命令，在网络唤醒不成功的情况下再以唤醒短消息的形式唤醒车辆的方式来说，上述实施例二中的唤醒方案能在提高唤醒速度的基础上同步保持远程控制的成功率，以同时兼顾到快速唤醒车辆与成功唤醒车辆的双重需求，有效降低唤醒车辆的时延。
【实施例三】
图5示例性示出本申请实施例三提供的远程控制方法的流程示意图，该方法适用于车辆管理服务器、车辆中的通信模块和用户终端，例如图1所示意出的车辆管理服务器110、车辆120中的通信模块121和用户终端130。如图5所示，该流程包括如下步骤：
步骤501，通信模块登录车辆管理服务器。
步骤502，通信模块与车辆管理服务器按照第一预设周期协商获得更新的车载密钥。
步骤503，通信模块按照第二预设周期向车辆管理服务器发送有效网络地址，或者还可以实时地向车辆管理服务器发送变化的网络地址。
步骤504，车辆管理服务器更新本地存储的通信模块的网络地址，具体包括：如果在一个第二预设周期内接收到通信模块发送的网络地址，则将本地存储的网络地址更新为接 收到的网络地址且保持有效，如果在一个第二预设周期内未接收到通信模块发送的网络地址，则将本地存储的网络地址设置失效。
步骤505，用户终端登录车辆管理服务器。
示例性的，用户终端通过目标APP登录车辆管理服务器的具体操作可以参照如下几步：
第一步，用户在将新购入的车辆开回家后，可以在手机的目标APP上输入注册信息，注册信息可以包括用户账号和登录密码，还可以包括其它信息，具体不作限定。其中，用户账号可以是用户的手机号码，也可以是指车辆管理服务器分配给用户的标识符，还可以是指其它能够用于唯一标识用户的信息。
第二步，用户终端的目标APP根据用户输入的注册信息生成注册请求，并将注册请求发送给车辆管理服务器。且，为了保证注册请求在发送的过程中不被篡改，目标APP还可以先加密该注册请求再将加密后的注册请求发送给车辆管理服务器。或者，为了提高注册效率，目标APP还可以先压缩注册请求，再将压缩后的注请求发送给车辆管理服务器。或者，目标APP还可以先压缩注册请求，再加密压缩后的注册请求，最后将加密后的压缩注册请求发送给车辆管理服务器，以在快速传输注册请求的同时提高注册的安全性。
第三步，车辆管理服务器接收到注册请求后，先解析注册请求得到用户账号和登录密码，然后在本地新建一个文件夹，该文件夹可以以该用户的用户账号来命名，也可以以能够标志该用户的其它唯一标识来命名。车辆管理服务器可以将注册请求中携带的用户账号和登录密码存储在该文件夹中。示例性地，车辆管理服务器在生成该用户账号对应的文件夹之前，还可以先查询车辆管理服务器中是否已存在该用户对应的文件夹，若存在，则说明该用户之前已经注册过用户账号，因此车辆管理服务器可以直接向目标APP返回注册失败的响应消息。若不存在，则说明该用户还没有注册过用户账号，因此车辆管理服务器可以创建文件夹并执行对应的存储操作。在存储完成后，车辆管理服务器确定该用户账号注册成功，从而车辆管理服务器可以向目标APP发送注册成功的响应消息。
第四步，用户设备中的目标APP向用户显示注册成功的响应消息。
第五步，用户可以直接从注册成功的响应界面切换到登录界面，也可以先关掉目标APP再重新打开目标APP以直接进入登录界面。用户在登录界面上填写用户账号和登录密码，并点击登录按钮，以触发目标APP生成登录请求并发送给车辆管理服务器。
第六步，车辆管理服务器根据登录请求中携带的用户账号找到对应的文件夹，验证用户输入的登录密码是否为该用户账号对应的登录密码，若是，则验证通过，车辆管理服务器可以向目标终端中的目标APP返回主界面信息，以使目标APP加载主界面信息从而切换到主界面，若否，则验证不通过，车辆管理服务器可以向目标终端中的目标APP返回登录失败的响应消息，以便目标APP向用户显示登录失败。
需要说明的是，该部分内容中所涉及到的目标APP与车辆管理服务器的交互流程较为繁琐，且与本方案中的发明点关联不大，因此本申请实施例仅简略地以图5中显示出的“登录”来表示该部分内容，但这并不限定本申请中登录的具体实现方案。
步骤506，车辆管理服务器按照第三预设周期将本地存储的通信模块的网络地址发送给用户终端。
示例性的，车辆管理服务器中还可以维持第四计时器，第四计时器的计时时长为第三预设周期。在用户终端成功登录车辆管理服务器后，车辆管理服务器可以先将本地存储的通信模块的网络地址反馈给用户终端，并启动第四计时器。每当第四计时器计时到对应的 计时时长时，车辆管理服务器都可以重新将本地当前存储的通信模块的网络地址发送给用户终端，并重启第四计时器。其中，在发送网络地址时：如果本地存储的网络地址有效，则车辆管理服务器可以将该网络地址的具体内容发送给用户终端；如果本地存储的网络地址无效，则车辆管理服务器可以向用户终端发送失效指示信息而不发送网络地址的具体内容，或者也可以不执行发送操作而是直接重启第四计时器，直至在某个第四计时器达到计时时长的时刻且网络地址也有效时，再重新发送网络地址的具体内容。如此，无论是车辆管理服务器只周期同步有效的网络地址给用户终端，还是同时周期同步有效网络地址和无效指示信息给用户终端，都能在通信模块网络链路较好的情况下及时让用户终端获知到通信模块最新的网络地址，且还能在通信模块网络不好的情况下让用户终端了解网络链路当前的异常情况，便于为用户终端后续是否通过网络方式发送网络地址提供决策依据。
示例性的，车辆管理服务器在用户终端成功登录车辆管理服务器后还可以执行如下步骤507：
步骤507，车辆管理服务器实时地向用户终端发送本地存储的通信模块的变化的网络地址。
在上述步骤507中，车辆管理服务器还可以监测自己存储的网络地址，一旦发现自己存储的网络地址发生变化，则实时地将变化的网络地址发送给用户终端。对应的，用户终端在接收到车辆管理服务器发送的变化的网络地址后，也可以使用变化的网络地址更新本地存储的通信模块的网络地址。如此，即使车辆管理服务器本地存储的网络地址在一个第三预设周期的时长间隔内发生了变化，用户终端也能及时获取到变化后的最新的网络地址，提高用户终端本地存储网络地址的准确性。
需要说明的是，在车辆管理服务器既周期发送网络地址又实时发送变化的网络地址的情况下，车辆管理服务器可以以最新发送的信息为基准重启第四计时器。例如，车辆管理服务器在某一时刻发送本地存储的网络地址后启动第四计时器，如果在还没计时到第三预设时长之前，又实时发送了变化的网络地址，则车辆管理服务器可以再重启第四计时器，以避免短时间内重复发送相同的网络地址，有效节省车辆管理服务器的通信损耗。
示例性地，在上述步骤506和步骤507中，为保持车辆管理服务器和用户终端更新网络地址的一致性，车辆管理服务器中也可以维持第三计时器但不维持第四计时器，在用户终端登录车辆管理服务器之后，车辆管理服务器每接收到通信模块发送的一个有效网络地址或变化的网络地址之后，都可以在更新本地存储的网络地址的同时，将接收到有效网络地址或变化的网络地址发送给用户终端，同步实现用户终端在同一时刻与车辆管理服务器同步通信模块的网络地址的操作。
应理解，车辆管理服务器与用户终端之间可以以明文的形式交互通信模块的网络地址，也可以使用用户密钥加密后以密文的形式交互通信模块的网络地址，具体不作限定。
步骤508，用户终端更新本地存储的通信模块的网络地址。
在上述步骤508中，在车辆管理服务器发送网络地址或无效指示信息给用户终端的情况下，如果用户终端接收到的是网络地址，则车辆管理服务器可以直接将本地存储的通信模块的网络地址更新为接收到的网络地址，如果用户终端接收到的是无效指示信息，则车辆管理服务器可以将本地存储的通信模块的网络地址设置失效。在车辆管理服务器发送网络地址而不发送无效指示信息给用户终端的情况下，用户终端中还可以维持第五计时器，第五计时器的计时时长也为第三预设周期，用户终端每接收到车辆管理服务器发送的一个 网络地址(可能是周期发送的有效网络地址，也可能是实时发送的变化的网络地址)，都可以重启第五计时器。在计时到第五计时器的计时时长之前，如果用户终端接收到了新的网络地址，则可以将本地存储的网络地址更新为新接收到的网络地址。在计时到第五计时器的计时时长时，如果用户终端还未接收到新的网络地址，则可以将本地存储的网络地址设置失效。
步骤509，用户终端在存在远程控制需求时，根据本地存储的通信模块的网络地址、唤醒命令和远程控制命令生成第二唤醒/远程控制IP数据包，使用车用交互密钥加密第二唤醒/远程控制IP数据包，得到加密后的第二唤醒/远程控制IP数据包。
步骤510，用户终端将加密后的第二唤醒/远程控制IP数据包发送给通信模块。
在上述步骤509和步骤510中，通过使用车用交互密钥加密完成通信模块与用户终端之间的数据交互，不仅能保证通信模块与用户终端之间数据交互的安全性，还能尽量使通信模块准确识别非法用户终端伪造的控制命令，提高远程控制车辆的安全性。
具体实施中，当用户终端上的目标APP检测到用户选中某个远程控制命令时，目标APP可以先查询本地存储的通信模块的网络地址是否有效。如果有效，说明通信模块当前大概率处于网络较好的区域，通过网络形式能更快唤醒车辆和控制车辆，因此，用户终端上的目标APP可以将该网络地址放在IP数据包的包头中，将唤醒命令和选中的远程控制命令放在一个IP数据包的包体或分别放在两个IP数据包的包体中，生成第二唤醒/远程控制IP数据包，以便通过网络形式发送给通信模块。如果无效，说明通信模块当前可能处于网络不好的区域，用户终端当前时段内很难通过网络形式唤醒和控制车辆，因此，用户终端上的目标APP可以不生成第二唤醒/远程控制IP数据包，而是直接按照常规的流程完成对车辆的唤醒和远程控制。
示例性的，用户终端还可以提前将短信APP的使用权限授权给目标APP。如此，在确定通信模块的网络地址无效时，用户终端上的目标APP也可以调用短信APP的权限直接向用户车辆发送唤醒短消息，例如同时将第二唤醒/远程控制IP数据包和唤醒短消息发送给通信模块。如此，该示例能通过用户终端以网络形式和短信形式同时指示车辆唤醒，不仅能在快速唤醒车辆的同时兼顾唤醒车辆的成功概率，还能通过用户终端自己完成对通信模块的整个控制逻辑，而可以不再需要车辆管理服务器进行转发，在降低用户终端的通信损耗的情况下，进一步提高远程控制的时效性。
在一种可选地实施方式中，用户终端还可以执行如下步骤511至步骤513：
步骤511，用户终端在发送加密的第二唤醒/远程控制IP数据包的同时，将远程控制命令(即第一远程控制命令)发送给车辆管理服务器。
步骤512，车辆管理服务器根据本地存储的通信模块的网络地址、唤醒命令和远程控制命令，生成第一唤醒/远程控制IP数据包，使用最新协商的车载密钥加密第一唤醒/远程控制IP数据包，得到加密后的第一唤醒/远程控制IP数据包。
步骤513，车辆管理服务器将加密后的第一唤醒/远程控制IP数据包和/或唤醒短消息发送给通信模块。
在上述步骤513中，车辆管理服务器可以通过如下任一方式执行发送操作：
发送方式一，车辆管理服务器发送第一唤醒/远程控制IP数据包但不发送唤醒短消息。如此，即使用户终端与通信模块之间的网络链路异常导致用户终端发送的第二唤醒/远程控制IP数据包没能成功发送给通信模块，只要车辆管理服务器与通信模块之间的网络链路正 常，则唤醒命令和远程控制命令也能以第一唤醒/远程控制IP数据包的网络形式快速发送给通信模块。即，通过车辆管理服务器和用户终端分别发送唤醒/远程控制IP数据包给通信模块，能尽量确保通信模块以网络形式快速接收到唤醒命令和远程控制命令。
发送方式二，车辆管理服务器发送唤醒短消息但不发送第一唤醒/远程控制IP数据包。该方式可以适用于用户终端中的目标APP不具有调用短信APP的权限导致用户终端未能发送唤醒短消息的场景。在该场景下，通过车辆管理服务器以短信形式发送唤醒命令，还能在通信模块网络不好的情况下，尽量通过正常的短信流程执行唤醒操作，提高唤醒车辆的成功概率。且，该发送方式由车辆管理服务器以短信形式独自发送唤醒短消息，以及由用户终端以网络方式独自发送唤醒命令和远程控制命令，能在保证网络和短信形式都覆盖的情况下，分散车辆管理服务器和用户终端的工作压力，节省车辆管理服务器和用户终端的处理资源。
发送方式三，车辆管理服务器同时发送第一唤醒/远程控制IP数据包和唤醒短消息。首先，该方式通过车辆管理服务器和用户终端分别发送唤醒/远程控制IP数据包，能提高通信模块网络接收唤醒命令和远程控制命令的概率。其次，该方式通过车辆管理服务器发送唤醒短消息以作为网络发送形式外的补充机制，能在通信模块网络不好导致通信模块无法接收到车辆管理服务器和用户终端的唤醒/远程控制IP数据包的情况下，尽快切换至正常的短信流程唤醒车辆，在减小远程控制时延的同时还可保证唤醒车辆的成功率。
可知，在上述步骤511至步骤513中，通过在用户终端的直接唤醒和控制之余，向车辆管理服务器发送远程控制命令指示车辆管理服务器间接唤醒和控制，能通过多个途径的唤醒和控制操作，增大唤醒车辆和控制车辆的成功概率。
步骤514，通信模块判断最先接收到的信息为加密后的唤醒/远程控制IP数据包还是唤醒短消息：
当先接收到加密后的第二唤醒/远程控制IP数据包时，执行步骤515；
当先接收到加密后的第一唤醒/远程控制IP数据包时，执行步骤516；
当先接收到唤醒短消息时，执行步骤517。
步骤515，通信模块使用车用交互密钥对加密后的第二唤醒/远程控制IP数据包进行解密，得到唤醒命令和远程控制命令(即第三远程控制命令)，根据唤醒命令和远程控制命令唤醒车辆后直接执行远程控制。
在上述步骤515中，通信模块最先接收到加密后的第二唤醒/远程控制IP数据包，说明通信模块与用户终端之间的网络链路的传输效果比其它链路或短信的传输效果更好，因此，通信模块在确定远程控制执行完成后，可以直接通过与用户终端之间的网络链路向用户终端返回远程控制结果，而不再需要通过车辆管理服务器进行转发，以便更快地向用户传达远程控制结果，提高用户使用手机执行远程控制的体验。
步骤516，通信模块使用最近协商得到的车载钥对加密后的第一唤醒/远程控制IP数据包进行解密，得到唤醒命令和远程控制命令(即第二远程控制命令)，根据唤醒命令和远程控制命令唤醒车辆后直接执行远程控制。
在上述步骤516中，通信模块最先接收到加密后的第一唤醒/远程控制IP数据包，说明通信模块与车辆管理服务器之间的网络链路的传输效果比其它链路或短信的传输效果更好，通信模块与用户终端之间的网络链路可能出现问题。因此，通信模块在确定远程控制执行完成后，可以通过与车辆管理服务器之间的网络链路向车辆管理服务器返回远程控 制结果，以便通过车辆管理服务器转发给用户终端。
在上述步骤515和步骤516中，在通信模块先接收到任一加密后的唤醒/远程控制IP数据包的情况下，通信模块可以直接丢弃后续接收到的加密后的唤醒/远程控制IP数据包或唤醒短消息，以节省计算资源。
步骤517，通信模块根据唤醒短消息唤醒车辆。
在上述步骤517中，通信模块从按照常规流程唤醒车辆开始直至获取到远程车载命令的期间中，如果通信模块又接收到了加密后的第一唤醒/远程控制IP数据包或加密后的第二唤醒/远程控制IP数据包，意味着当前的网络链路重新恢复正常，通信模块可以不再等待常规鉴权完成后才启动远程控制，而是可以直接终止常规流程，并根据从加密后的第一唤醒/远程控制IP数据包或加密后的第二唤醒/远程控制IP数据包中解析出的远程控制命令直接启动远程控制，以降低远程控制的时延。当然，如果后续还接收到另一加密后的唤醒/远程控制IP数据包，则可直接丢弃。
在上述实施例三中，通过车辆管理服务器周期(或周期且实时)向用户终端同步通信模块的网络地址，使得用户终端能在存在远程控制需求时直接从本地获取通信模块的网络地址，以实现用户终端对车辆的直接唤醒和控制，该方式不仅有助于降低经由车辆管理服务器间接转发唤醒命令和远程控制命令所引入的时延，有效提高远程控制的效率，还能尽量分散车辆管理服务器的工作压力。且，通过以用户终端的网络形式、用户终端的短信形式、车辆管理服务器的网络形式和车辆管理服务器的短信形式中的至少两项向通信模块发送唤醒命令，能通过多种发送方式提高通信模块接收到唤醒命令的概率，提高成功唤醒车辆的可能性。此外，通过用户终端和车辆管理服务器分别以网络形式发送唤醒命令，还能尽量让通信模块以网络形式快速接收到唤醒命令和远程控制命令，降低远程控制车辆的时延。
在一种可选地实施方式中，针对于车辆管理服务器、用户终端和车辆中的通信模块中的每个设备，都可以包含信息维护模块和远程控制模块：信息维护模块用于维护在执行远程控制时会用到的一些信息，如网络地址以及与其它设备进行数据交互的密钥等；而远程控制模块则用于使用信息维护模块所维护的信息完成与其它设备的远程控制流程。其中，信息维护模块和远程控制模块可以分别位于不同的线程，且各自互不干扰，以在维持正常的远程控制流程的同时，实时更新远程控制所需的信息，兼顾远程控制的准确性与及时性。
下面分别对每种设备中的这两个模块进行详细介绍。
车辆管理服务器
图6示例性示出本申请实施例提供的一种车辆管理服务器的内部架构示意图，如图6所示，车辆管理服务器600中可以包括服务器信息维护模块610和服务器远程控制模块620，服务器信息维护模块610用于维护车辆管理服务器600本地存储的通信模块的网络地址和与通信模块最新协商的车载密钥，服务器远程控制模块620用于根据服务器信息维护模块610中维护的通信模块的网络地址和车载密钥向通信模块发起远程控制。
如图6所示，在实施中，服务器信息维护模块610在确定通信模块登录车辆管理服务器后，可以并行执行如下四个操作：
操作一，开始运行第三计时器，如果在第三计时器超时之前(即计时到第二预设时长之前)接收到了通信模块发送的加密的网络地址(如携带加密的有效网络地址或加密的变 化的网络地址的心跳数据包)，则通过使用最新协商的车载密钥解密该加密的网络地址获得通信模块的网络地址，以此更新本地存储的通信模块的网络地址，并重启第三计时器。如果在第三计时器超时之前未接收到通信模块发送的加密的网络地址，则设置本地存储的通信模块的网络地址为无效状态，并重启第三计时器。
操作二，如果接收到通信模块发送的密钥更新请求，则为通信模块设置新的车载密钥，并返回给通信模块。
操作三，开始运行第四计时器，每当第四计时器超时(即计时到第三预设时长)，则将本地存储的通信模块的网络地址发送给用户终端，并重启第四计时器。
操作四，实时监测本地存储的通信模块的网络地址，一旦监测到网络地址发生变化，则将变化的网络地址发送给用户终端，并重启第四计时器。
需要说明的是，上述操作一是指车辆管理服务器单独按照第二预设时长或实时接收通信模块的网络地址，操作三和操作四是指车辆管理服务器单独按照第三预设时长或实时向用户终端发送通信模块的网络地址，第二预设时长和第三预设时长可以为不同时长。在另一种情况下，第二预设时长和第三预设时长也可以是同一时长，在这种情况下，上述操作一、操作三和操作四也可以替换为如下操作：
操作五，开始运行第三计时器，如果在第三计时器超时之前(即计时到第二预设时长之前)接收到了通信模块发送的加密的网络地址，则通过使用最新协商的车载密钥对加密的网络地址进行解密以获得通信模块的网络地址后，将获取的网络地址发送给用户终端，并更新本地存储的通信模块的网络地址，重启第三计时器。如果在第三计时器超时之前未接收到车辆管理服务器发送的加密的网络地址，则设置本地存储的通信模块的网络地址为无效状态，重启第三计时器，将失效指示信息发送给用户终端以指示用户终端失效本地存储的网络地址，或者不发送任何信息以等待用户终端自己主动失效本地存储的网络地址。
相应的，服务器远程控制模块620在接收到用户终端的远程控制命令后，可以执行如下操作：
获取服务器信息维护模块610维护的最新的车载密钥和本地存储的通信模块的网络地址。若通信模块的网络地址有效，则根据该网络地址、以及唤醒命令和/或远程控制命令生成第一唤醒/远程控制IP数据包，使用最新的车载密钥加密第一唤醒/远程控制IP数据包后，将加密后的第一唤醒/远程控制IP数据包和唤醒短消息一起发送给通信模块。例如，根据网络地址和唤醒命令生成唤醒IP数据包，根据网络地址和远程控制命令生成远程控制IP数据包，对这两个IP数据包加密后连同唤醒短消息一起送给通信模块。或者，根据网络地址、唤醒命令和远程控制命令生成唤醒加远程控制IP数据包，对唤醒加远程控制IP数据包加密后连同唤醒短消息一起送给通信模块。若通信模块的网络地址无效，则向通信模块发送唤醒短消息。

如图7所示，在实施中，用户终端信息维护模块710在确定用户终端登录车辆管理服 务器后，可以执行如下操作：
开始运行第五计时器，如果在第五计时器超时之前(即计时到第三预设时长之前)，接收到了车辆管理服务器发送的加密的网络地址(如携带加密的有效网络地址或加密的变化的网络地址的心跳数据包)，则通过使用用户密钥对加密的网络地址进行解密后获得通信模块的网络地址，以此更新本地存储的通信模块的网络地址，并重启第五计时器。如果在第五计时器超时之前未接收到车辆管理服务器发送的加密的网络地址，或接收到车辆管理服务器发送的失效指示信息，则设置本地存储的通信模块的网络地址为无效状态，并重启第五计时器。
相应的，用户终端远程控制模块720在存在远程控制需求时，可以执行如下操作：
获取用户终端信息维护模块710维护的本地存储的通信模块的网络地址。若通信模块的网络地址有效，则根据该网络地址、以及唤醒命令和/或远程控制命令生成第二唤醒/远程控制IP数据包，使用车用交互密钥加密第二唤醒/远程控制IP数据包后发送给通信模块。或者，还可以向车辆管理服务器发送远程控制命令。或者，在具有发送信息的权限时，还可以同时将唤醒短消息也发送给通信模块。若通信模块的网络地址无效，则向车辆管理服务器发送远程控制命令，以经由车辆管理服务器以网络形式发送第一唤醒/远程控制IP数据包，和/或，以短信形式发送唤醒短消息。
车辆中的通信模块
图8示例性示出本申请实施例提供的一种通信模块的内部架构示意图，如图8所示，通信模块800中可以包括通信模块信息维护模块810和通信模块远程控制模块820，通信模块信息维护模块810用于与车辆管理服务器协商最新的车载密钥，以及向车辆管理服务器上报自己的网络地址，通信模块远程控制模块820用于根据通信模块信息维护模块810维护的车载密钥唤醒车辆后直接执行远程控制。
如图8所示，在实施中，通信模块信息维护模块810在确定通信模块登录车辆管理服务器后，可以并行执行如下三个操作：
操作一，开始运行第一计时器，每当第一计时器超时(即计时到第一预设时长时)时，向车辆管理服务器发送密钥更新请求，并保存车辆管理服务器返回的车载密钥，重启第一计时器。
操作二，开始运行第二计时器，每当第二计时器超时(即计时到第二预设时长时)时，使用最新协商得到的车载密钥加密自己当前的网络地址后发送给车辆管理服务器，并重启第二计时器。
操作三，实时监测自己的网络地址，一旦监测到网络地址发生变化，则使用最新协商得到的车载密钥加密变化的网络地址后发送给车辆管理服务器，并重启第二计时器。
相应的，通信模块远程控制模块820在接收到车辆管理服务器或用户终端的信息后，可以执行如下操作：
在最先接收到的信息为加密的唤醒/远程控制IP数据包的情况下：如果是车辆管理服务器发送的加密的第一唤醒/远程控制IP数据包，则使用通信模块信息维护模块810维护的最新的车载密钥对加密的第一唤醒/远程控制IP数据包进行解密，得到唤醒命令和远程控制命令；如果是用户终端发送的加密的第二唤醒/远程控制IP数据包，则使用车用交互密钥对加密的第二唤醒/远程控制IP数据包进行解密，得到唤醒命令和远程控制命令。之后，先根据唤醒命令唤醒车辆中的各个电子控制单元，再将远程控制命令发送给对应的电 子控制单元，以指示对应的电子控制单元执行远程控制。且，在此期间，还可以丢弃后续接收到的唤醒短消息或另一个加密后的唤醒/远程控制IP数据包。在最先接收到的信息为唤醒短消息的情况下，按照常规流程唤醒和远程控制车辆，即，先根据唤醒短消息唤醒车辆中的各个电子控制单元，再通过重新接入车辆管理服务器获取准确的车载密钥和通信模块的网络地址，并等待接收到车辆管理服务器发送的远程控制命令后，将远程控制命令发送给对应的电子控制单元，且，在接收到远程控制命令之前，若又接收到加密的唤醒/远程控制IP数据包，则可以不再执行常规流程，而是直接对加密的唤醒/远程控制IP数据包进行解密以获得远程控制命令，并发送给对应的电子控制单元，以直接启动远程控制。
在上述实施方式中，通过在每个设备中设置两个并行的模块分别执行信息维护和远程控制，能解耦远程控制业务的信息管理操作和控制执行操作，有效降低两个操作相互干扰的概率，提高对整个远程控制流程的集中管控。
本申请上述实施例中的远程控制方案能从多个角度综合降低远程控制的时延。下面通过一个具体的实验数据，说明本申请实施例中的远程控制方案相比于业界常用的两种远程控制方案在降低远程控制时延上的突出性。需要说明的是，下文中只将数据中转流程所耗费的时间作为时延，而不考虑执行唤醒操作和执行远程控制操作的执行时间。
图9示例性示出业界常用的一种远程控制方案的时延分析示意图，如图9所示，该方案主要通过如下几个步骤完成远程控制：
步骤901，用户终端向车辆管理服务器发送远程控制命令，大约需要500ms；
步骤902，车辆管理服务器向车辆中的通信模块发送唤醒短消息，短信传输唤醒短消息大约需要15s，通信模块在唤醒车辆时向包含车载网关在内的车内部件发送唤醒命令大约需要4s；
步骤903，通信模块确定成功唤醒车辆后，向车辆管理服务器发送唤醒成功响应，并向车辆管理服务器发起接入流程，接入成功后与车辆管理服务器交互最新协商的车载密钥，并将自己的网络地址发送给车辆管理服务器，大约需要3000ms；
步骤904，车辆管理服务器根据步骤903中协商得到的车载密钥以及接收到的通信模块的网络地址，以加密的形式向通信模块发送远程控制命令，大约需要500ms；
步骤905，通信模块确定执行完远程控制命令后，向车辆管理服务器返回远程控制结果，大约需要500ms；
步骤906，车辆管理服务器向用户终端转发远程执行结果，大约需要500ms。
根据上述内容可知，采用如图9所示意的现有方案，除去执行唤醒和执行远程控制所必须的执行时间之外，还需要大概24s(500ms+15s+4s+3000ms+500ms+500ms+500ms)。即，用户在手机上点击远程控制命令后，至少需要等待24s才能获取到远程控制结果。虽然该方案的远程控制时延较大，但短信方式能大概率让通信模块接收到唤醒短消息，而不依赖于通信模块的网络状况，因此唤醒的成功率比较高。
图10示例性示出业界常用的另一种远程控制方案的时延分析示意图，在该方案中，通信模块在登录车辆管理服务器后，会周期性地将自己的网络地址同步给车辆管理服务器，以便车辆管理服务器能直接利用网络形式唤醒车辆。如图10所示，该方案主要通过如下几个步骤完成远程控制：
步骤1001，用户终端向车辆管理服务器发送远程控制命令，大约需要500ms；
步骤1002，车辆管理服务器先根据通信模块周期同步的最新的网络地址，通过网络形式向通信模块发送唤醒数据包，并等待通信模块的唤醒成功响应。如果在2s的时间内还未收到唤醒成功响应，则再通过短信形式向通信模块发送唤醒短消息，并等待通信模块的唤醒成功响应。在该过程中，如果唤醒数据包能成功发送给通信模块，则大约需要500ms即可开始唤醒车辆，而通信模块在唤醒车辆时向包含车载网关在内的车内部件发送唤醒命令大约需要4s，即共计约4.5s。如果唤醒数据包无法成功发送给通信模块，则大约需要21s(即发出唤醒数据包后等待的2s、发送唤醒短消息所需的15s以及通信模块向车内部件发送唤醒命令所需的4s)才能开始唤醒车辆。即，大约需要4.5s～21s之间的一个时长。
步骤1003，通信模块确定车辆成功唤醒后，向车辆管理服务器发送唤醒成功响应，与车辆管理服务器交互最新协商的车载密钥，并将自己的网络地址发送给车辆管理服务器，大约需要3000ms；
步骤1004，车辆管理服务器根据步骤1003中协商得到的车载密钥以及接收到的通信模块的网络地址，以加密的形式向通信模块发送远程控制命令，大约需要500ms；
步骤1005，通信模块确定执行完远程控制命令后，向车辆管理服务器返回远程控制结果，大约需要500ms；
步骤1006，车辆管理服务器向用户终端转发远程执行结果，大约需要500ms。
根据上述内容可知，采用如图10所示意的现有方案，除去执行唤醒和执行远程控制所必须的执行时间之外，至少需要大概9.5s(500ms+4.5s+3000ms+500ms+500ms+500ms)的时间。即，用户在手机上点击远程控制命令后，需要等待9.5s才能获取到远程控制结果。该方案所需的最短时延比图9所示意的方案的时延明显降低，但该最短时延只能在通信模块与车辆管理服务器之间的网络通信状况非常好的情况下才能实现。当通信模块与车辆管理服务器之间的网络通信状况不好时，该方案需要等待2s的时长后切换至唤醒短消息的方式重新执行唤醒，也即是说，最差情况下会需要大概26s(500ms+2s+15s+4s+3000ms+500ms+500ms+500ms)的时间。可见，图10所示意的现有方案实际上是以牺牲唤醒成功率为条件实现降低唤醒时延的目的，无法同时兼顾到降低唤醒时延和提高唤醒成功率。
图11示例性示出本申请实施例二中的一种远程控制方案的时延分析示意图，在该方案中，通信模块在登录车辆管理服务器后，不仅会周期(或周期且实时)向车辆管理服务器发送自己的网络地址，还会周期与车辆管理服务器交互协商最新的车载密钥，以便车辆管理服务器能直接利用最新的网络地址和车载密钥以网络形式唤醒车辆后直接进行远程控制。如图11所示，该方案主要通过如下几个步骤完成远程控制：
步骤1101，用户终端向车辆管理服务器发送远程控制命令，大约需要500ms；
步骤1102，车辆管理服务器根据通信模块周期同步的最新的网络地址和周期协商的车载密钥，通过网络形式向通信模块同时发送加密的唤醒命令和远程控制命令，且同时还会通过短信形式向通信模块发送唤醒短消息。在该过程中，如果唤醒命令和远程控制命令能以网络形式成功发送给通信模块，则大约需要500ms即可开始唤醒并远程控制车辆，而通信模块在唤醒车辆时向包含车载网关在内的车内部件发送唤醒命令大约需要4s，即共计约4.5s。即使唤醒命令和远程控制命令无法以网络形式成功发送给通信模块，也能利用同时发送的唤醒短消息直接切换至短信形式唤醒车辆，即短信传输唤醒短消息所需的15s和通信模块向车内部件发送唤醒命令所需的4s，共计19s。即，该方式大约需要4.5s～19s之间 的一个时长。
首先，上述步骤1102同时以网络方式和短信方式发送相关信息，而不是先网络发送不成功再切换至短信发送，因此能在网络方式不成功的情况下节省中间等待所需的2s。其次，在唤醒命令和远程控制命令能以网络形式成功发送给通信模块的情况下，通信模块在唤醒车辆后直接执行远程控制，在这两个操作之间无需再与车辆管理服务器协商车载密钥和网络地址，也无需再发送远程控制命令，因此该方案还能节省协商车载密钥和网络地址所需的3000ms和发送远程控制命令所需的500ms。
步骤1103，通信模块确定执行完远程控制命令后，向车辆管理服务器返回远程控制结果，大约需要500ms；
步骤1104，车辆管理服务器向用户终端转发远程控制结果，大约需要500ms。
根据上述内容可知，采用如图11所示意的方案，除去执行唤醒和执行远程控制所必须的执行时间之外，最短只需要大概6s(500ms+4.5ms+500ms+500ms)的时间。即，用户在手机上点击远程控制命令后，最短只需等待6s就能获取到远程控制结果。可知，该方案所需的最短时延6s，相比于图9中固定的24s时延来说优化了大约75％(即(24-6)/24)，相比于图10中的最短时延9.5s来说优化了大约36.8％(即(9.5-6)/9.5)，该方案所需的最短时延相比于图9和图10所示意的现有方案明显降低。即使在通信模块与车辆管理服务器的网络通信状况不好的情况下，该方案也能直接切换至同时发送的唤醒短消息来唤醒车辆，即，最差情况下也只会与图9中的方案具有相同时延。且，该方案为保证最短时延下唤醒车辆的成功率，还在周期向车辆管理服务器同步通信模块的网络地址之余，实时同步通信模块变化的网络地址，进一步增加了以最短时延控制车辆的成功概率。可见，图11所示意的方案能同时兼顾到降低唤醒时延和提高唤醒成功率的统一。
图12示例性示出本申请实施例三中的一种远程控制方案的时延分析示意图，在该方案中，车辆管理服务器在用户终端成功登录车辆管理服务器后，会周期(或周期且实时)向用户终端发送通信模块的网络地址，以便用户终端能直接利用最新的网络地址以网络形式唤醒车辆后直接进行远程控制。如图12所示，该方案主要通过如下几个步骤完成远程控制：
步骤1201，用户终端在存在远程控制需求时，直接根据车辆管理服务器最新发送的通信模块的网络地址，通过网络形式向通信模块同时发送加密的唤醒命令和远程控制命令，大约需要500ms，而通信模块向车内部件发送唤醒命令大约需要4s，共计4.5s。且，用户终端还会同时向车辆管理服务器发送远程控制命令，大约需要500ms。
在用户终端能以网络形式成功发送唤醒命令和远程控制命令的情况下，通信模块在唤醒车辆后直接执行远程控制，而不再需要车辆管理服务器间接唤醒和远程控制，因此能节省通过车辆管理服务器中转数据所引入的时延。在用户终端无法以网络形式成功发送唤醒命令和远程控制命令的情况下，用户终端通过车辆管理服务器间接按照图11中的方案唤醒和远程控制车辆，即最差也与图11中的方案具有相同时延。
步骤1202，通信模块确定执行完远程控制命令后，直接向用户终端返回远程控制结果，大约需要500ms。
根据上述内容可知，采用如图12所示意的方案，除去执行唤醒和执行远程控制所必须的执行时间之外，最短只需要大概5秒(4.5ms+500ms)的时间。该方案所需的最短时延比图11所示意的方案中的时延还要低。即使在用户终端和通信模块的网络通信状态不好 的情况下，该方案也能直接切换为通过同时发送给车辆管理服务器的远程控制命令来唤醒和远程控制车辆，即，最差情况下也只会与图11所示意的方案具有相同时延。且，该方案为保证最短时延下唤醒车辆的成功率，还在车辆管理服务器周期向用户终端同步通信模块的网络地址之余，实时同步通信模块变化的网络地址，进一步增加了以最短时延控制车辆的成功概率。可见，图12所示意的方案也能同时兼顾到降低唤醒时延和提高唤醒成功率的统一。
综上所述，本申请的上述实施例给出的远程控制方案相比于图9及图10所给出的现有方案来说，能在大大降低远程控制时延的基础上，尽量保证原有甚至实现更高的唤醒成功率。
