Description

一种车辆升级方法及装置 技术领域
本申请涉及网联车技术领域，尤其涉及一种车辆升级方法及装置。
背景技术
空中下载技术(Over the Air，OΤΑ)是一种通过无线网络进行数据下载的技术，现已被广泛应用于智能电视、手机、平板电脑、机顶盒等设备的升级中。OTA技术主要通过网络(例如WIFI、3G、4G等等)下载OTA升级包来自动升级(也支持通过下载OTA升级包到SD卡来升级)，OTA升级速度快、对数据的影响小，因此随着智能网联车的发展，OTA升级成为了车辆功能升级的主要方式，车辆厂商(或者说原始设备制造商(Original Equipment Manufacturer，OEM厂商))通过OTA技术升级车辆的相关软件或固件，有利于厂商减少召回成本、快速响应需求、提升用户体验。
车辆中包含多个节点，多个节点之间可以互相关联、互相配合。因此升级车辆时往往涉及到多个部件的节点，需要一个OTA主(Master)模块来协调各个节点的升级。OTA Master模块配置在车辆的其中一个(或者也可以是多个)节点(例如网关(gateway，GW)、汽车盒子Tbox)上，协调控制其他节点中的OTA从(Slave)模块，共同完成车辆的升级。但是通过OTA master模块来下载安装包、协调其他节点升级的方式中，OTA master模块需要下载、分发多个OTA slave的升级包，这会给OTA Master的存储和负载带来很大负担，使得车辆的升级效率和车辆的稳定性收到影响。比如，如果升级包很大，那么OTA Master存储空间可能不够，从而使得部分车辆部件不能及时升级。再如，随着车辆的结构越来越复杂，通过这样的方式升级车辆效率将越来越低，不能满足用户的需求。
发明内容
本申请实施例公开了一种车辆升级方法及装置，能够提高车辆升级效率，提高车辆稳定性。
第一方面，本申请实施例公开了一种车辆升级方法，包括：
服务器确定车辆内的至少两个部件组，其中，每个部件组包括一个用于控制所述部件组内的部件进行OTA升级的升级控制部件；
所述服务器为所述至少两个部件组中的第一部件组生成第一升级包，其中，所述第一部件组的升级控制部件为第一升级控制部件；
所述服务器向所述第一升级控制部件发送所述第一升级包，所述第一升级包用于对所述第一部件组内的部件进行升级。
本申请实施例中，服务器为车辆中的部件组生成该部件组的升级包，然后将升级包分发部件组的升级控制部件，从而使得升级控制部件对部件组内的部件进行升级。相比由一个OTA升级主模块对车辆中的各个部件进行集中升级控制，提高了车辆升级效率。进一步的，各个部件的升级可以由比较近的升级控制部件来进行，降低车辆升级的复杂度。此外， 由每个部件组的升级控制部件来控制组内的部件，可以及时监控、检测、指挥升级，因此可以尽快完成部件的升级，提高车辆的稳定性。
其中，本申请各实施例中提到的服务器，可以是一个服务器、也可以是多个服务器组成的服务器集群。具体的，服务器既可以包含一个集中存储升级包的服务器，也可以包含分布式存储升级包、分组配置信息或升级策略信息的分布式架设的服务器集群。例如，分布式服务器可以是由多个服务器组成的服务器集群，集群中可以包括云计算服务器、内容分发网络(Content Delivery Network，CDN)服务器、网络时间协议(Network Time Protocol，NTP)、域名解析***(Domain Name System，DNS)服务器等等其中，各个服务器之间可以相互协调，共同完成计算、数据存储、通信等功能，为了方便描述，本申请实施例中将单个服务器、分布式服务器、服务器集群统称为服务器。
本申请实施例中提到的部件组，是由车辆内的至少一个部件组成的，每个部件组包括一个用于控制部件组内的部件进行OTA升级的升级控制部件，还可以包括车辆内的其他部件。当部件组内仅包括一个部件时，该部件既是该部件组的升级控制部件，也是该部件组的待升级部件。
其中，升级控制部件用于控制部件组内的部件完成升级，可以是车辆中的一个单独的部件，也可以作为一个模块部署在其中一个部件内(例如可以部署在域控制器和/或整车集成单元中)。
进一步地，所述服务器为所述至少两个部件组中的第二部件组生成第二升级包，其中，所述第二部件组的升级控制部件为第二升级控制部件；
所述服务器向所述第二升级控制部件发送所述第二升级包，所述第二升级包用于对所述第二部件组内的部件进行升级。

上述说明了下载升级数据包的方式，服务器可以为第一升级包分配下载地址，该下载地址可以先发送给OTA升级主节点，再由OTA升级主节点将下载地址分发给需要该第一升级包来完成升级的第一升级控制部件。由于下载地址的数据大小通常是比较小的，因此先发送给升级主节点再分发对应的各组的升级控制部件，相比服务器直接与组内的升级控制部件建立连接发送下载地址，可以节省网络资源的开销、减少复杂度，从而提高升级效率。
进一步的，服务器还可以将下载地址进行签名，该OTA升级主节点可以验证该签名，从而确保下载地址的正确性，避免下载地址遭到篡改，保证车辆升级过程的安全性。

可以看出，服务器根据部件的版本信息，确定第一升级包。进一步的，服务器还可以根据第一部件组中的部件的版本信息，确定第一部件组中存在需要进行版本升级的部件，从而将升级的数据打包，得到该第一升级包。
第二方面，本申请实施例公开了一种车辆升级方法，包括：

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。需要说明的是，本申请中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面先对本申请实施例的***架构和业务场景进行描述。需要说明的是，本申请描述的***架构及业务场景是为了更加清楚的说明本申请的技术方案，并不构成对于本申请提供的技术方案的限定，本领域普通技术人员可知，随着***架构的演变和新业务场景的出现，本申请提供的技术方案对于类似的技术问题，同样适用。
请参见图1，图1是本申请实施例提供的一种车辆升级***的示意图，包括OTA服务器(server)101、OTA主模块(Master)102和OTA从模块(slave)103。其中：
OTA服务器101用于将升级数据包发送给OTA Master，在一些具体的实施场景中，也将OTA服务器称为OTA云端。
OTA主模块(Master)102是具有数据收发能力的电子设备，可以接收OTA服务器101发送的升级包，根据该升级包更新车辆的部件。具体的，OTA主模块102将接收的升级包分发给车辆中的一个或者多个OTA从模块103，指挥该一个或者多个OTA从模块103安装 和激活升级包，完成升级。
请参见图2，图2是本申请实施例提供的一种可能的车辆的架构示意图，包括OTA云端201和车辆202。车辆202是基于车辆电子电气(Electrical/Electronic Architecture，E/E)架构的车辆，参见区域203，车辆202可以包括以下部件：移动数据中心(Mobile Data Center，MDC)、人机交互(Human–Machine Interaction，HMI)、网关(gateway，GW)、汽车盒子(Telematics BOX，Tbox或者称为TCU)、电子控制单元(Electronic Control Unit，ECU)等模块。其中，GW是整车电子电气架构中的核心部件，其作为整车网络的数据交互枢纽，可将控制区域网络(Controller Area Network，CAN)、局域互联网络(Local Interconnect Network，LIN)、多媒体数据传输(Media Oriented System Transport，MOST)、FlexRay等网络数据在不同网络中进行路由。MDC是汽车的智能车载计算平台。T-BOX主要用于和汽车外部、后台***和手机应用(application，APP)通信。HMI是汽车的信息娱乐***。ECU是汽车专用微机控制器。
在车辆202的GW中部署有升级主模块(update master，可以看作是OTA master)，车辆202的其余各个模块中部署有升级从模块(update slave，可以看作是OTA slave)，GW中的升级主模块接收OTA云端发送的升级包，将其分发给对应部件的升级从模块，使得升级从模块安装和激活升级包，完成部件的升级。可以看出，整车的升级包都是由GW中的升级主模块来负责下载、以及指挥各部件进行安装。这会给升级主模块的存储和负载带来很大负担。比如，如果升级包很大，那么可能出现升级主模块存储空间不够的问题。
此外，由于图2中的车辆是基于车辆202是基于电子电器架构的车辆，GW是整车电子电气架构中的核心部件，因此可以将升级主模块部署在GW中，可以减少路由的复杂度，但是在其他车辆架构中，随着部件的数量增加，结构复杂，如果由升级主模块去升级距离较远的ECU(其中，距离远可以理解为从升级主模块到达待升级ECU所需要经过的跳数较多)，对车辆升级的效率也会有影响。请参见图3，图3是本申请实施例提供的一种基于中央计算架构的车辆的架构示意图，车辆30是基于中央计算架构(Central Computing Architecture，CCA)的车辆，CCA包括若干整车集成单元(vehicle integrated/integration unit，VIU)和多个汽车零部件，多个VIU组成一个环网，实现高带宽(高清摄像头、高清显示)、低时延、高可靠处理能力来持续提升竞争力，简化车载网络配置、提升升级维护效率。汽车零部件(例如ECU、Tbox等等)可以连接到VIU，或者可以连接至域控制单元(domain controller，DC)例如座舱域控制器(Cockpit Domain Controller，CDC)、MDC、整车域控制器(Vehicle Domain Controller，VDC)，再通过DC连接至VIU。这样一来，避免了传统的实现车辆中电子控制功能的***中每个汽车的部件都需要通过各自的线束连接至域控制单元DC，有利于减少实现汽车中电子控制功能的***中的线束长度。
如图3所示，相比于图2中车辆202所使用的汽车电子电气(Electrical/Electronic Architecture，E/E)架构，车辆30的多个部件中，一部分部件连接VIU1(例如ECU2.1、ECU2.2、Tbox等)，一部分部件连接VIU2(例如ECU4.1、ECU4.2等等)，一部分部件连接VIU3，一部分部件连接VIU4。此时，若升级主模块部署在Tbox中，对于需要升级的ECU5.1来说，那么分发的升级包的路径会经过VIU1、VIU2、VIU3的总线，然后通过VIU3到ECU5.1中，可以看出，由于升级的路线复杂(可以理解为经过的跳数较多)，因此通过 升级主节点分发升级包的方式，车辆升级的复杂度会提高，效率也受到影响。
需要说明的是，图3所示的架构中，各个节点中的连接线路可以是基于以太网的总线、也可以是控制区域网络(Controller Area Network，CAN)总线、局域互联网络(Local Interconnect Network，LIN)总线、多媒体数据传输(Media Oriented System Transport，MOST)总线、FlexRay等等中的一个或者多个。
请参见图4，图4是本申请实施例提供的一种车辆升级方法的流程示意图，该方法包括但不限于如下步骤：
步骤S401：OTA升级主节点获取车辆中部件的版本信息。
具体的，车辆中的部件可以是具有数据处理能力或者具有数据收发能力的电子设备，例如，可以为车辆中的各种GW、Tbox、VIU、DC、ECU等等，或者还可以车辆中的媒体设备如摄像头、雷达等等。其中，ECU由处理器、存储器、输入/输出(I/O)接口、模数转换器(A/D)以及整形、驱动等大规模集成电路中的一个或者多个组成，可以完成多种多样的功能。
其中，OTA升级主节点是支持OTA技术的电子设备，OTA升级主节点可以与服务器、以及车辆内的各个升级控制部件进行通信，用于协助完成车辆内的各个部件的升级。可选的，OTA升级主节点可以是车辆中的一个单独的部件，也可以作为一个模块部署在其中一个部件内。进一步的，该OTA升级主节点可以是一个硬件模块，也可以是一个计算机程序。例如，车辆的Tbox中可以包含有OTA模块，该OTA模块支持OTA技术，因此该Tbox可以看作是OTA升级主节点。再如，车辆中预先装配有一个支持OTA技术的部件，该部件中集成有处理器或者集成电路等，该支持OTA技术的部件可以看作是一个OTA升级主节点。
部件的版本信息可以是包括部件中的软件版本信息、标定数据版本信息、硬件版本信息(例如，硬件的规格、型号、硬件的标识等等，不同硬件的版本信息所需要升级的软件可能不同)、部件的标识(identify，ID)、部件的版本号等等中的一个或者多个。例如，车辆的摄像头中包括摄像程序，该摄像程序的程序版本号“v12.5.8”即可以是该摄像头的版本信息，再如，摄像头中的主控芯片、感光芯片的规格型号也可以是该摄像头的版本信息。
OTA升级主节点获取车辆中多个部件的版本信息，具体可以有以下几种设计：
设计一：OTA升级主节点接收第一升级控制部件发送的第一部件组内的部件的版本信息。具体的，车辆中可以包括至少两个部件组，每一个部件组中包括一个升级控制部件，该升级控制部件用于控制部件组内的部件完成升级，可以是车辆中的一个单独的部件，也可以作为一个模块部署在其中一个部件内(例如可以部署在DC和/或VIU中)。其中，第一部件组的升级控制部件为第一升级控制部件。第一升级控制部件可以收集第一部件组内的部件的版本信息，然后将部件的版本信息发送给OTA升级主节点，相应的，OTA就接收到来自第一升级控制部件发送的第一部件组内的部件的版本信息。
设计二：OTA升级主节点接收汇报节点发送的车辆内的部件的版本信息。
其中，汇报节点可以是车辆内部的域控制器、网关、分布式网关、整车集成单元等，汇报节点可以向OTA升级主节点上报其所收集的部件的版本信息。例如CDC可以收集座 舱域中的多个部件(例如麦克风、雷达、音响、无钥匙启动模块等等中的一个或者多个)的版本信息，然后可以将该版本信息发送给OTA升级主节点，后续OTA升级主节点可以将该版本信息发送给服务器，便于确定需要更新的部件。
设计三：OTA升级主节点可以接收至少一个部件发送的该至少一个部件的版本信息。
具体的，车辆中的部件可以周期或者非周期的向OTA升级主节点发送自己的版本信息(或者自己存储的其他部件的版本信息，或者转发其他部件的版本信息)，相应的，OTA升级主节点接收至少一个部件发送的该至少一个部件的版本信息。可选的，车辆中的部件可以在每次升级版本后，向OTA升级主节点发送该部件的版本信息。
此外，OTA升级主节点中还可以预先配置有所在的车辆中的部件的版本信息，又或者OTA升级主节点还可以通过管理接口查询到车辆的部件的版本信息。
可选的，该车辆升级方法还包括步骤S402，具体如下：
步骤S402：OTA升级主节点确定车辆内的至少两个部件组。这里的可选可以理解为，在实际的处理过程中，OTA升级主节点可以确定车辆内的至少两个部件组，也可以不确定车辆内的至少两个部件组。例如，车辆内的部件组可以是预先配置或者预先定义好的，此时OTA升级主节点无需重新确定车辆内的至少两个部件组。具体可以取决于OTA升级主节点的实现、预先的约定或者标准的定义。
具体地，车辆的部件组是由车辆内的至少一个部件组成的，每个部件组包括一个用于控制部件组内的部件进行OTA升级的升级控制部件，还可以包括车辆内的其他部件，例如Tbox、ECU等等。当部件组内仅包括一个部件时，该部件既是该部件组的升级控制部件，也是该部件组的待升级部件。
可选的，该至少两个部件组可以是OTA升级主节点根据预先配置的策略或者车内的节点连接关系、各个节点的配置或负载中的至少一个来确定的。可选的，该分组策略可以是预先定义或者预先配置的分组方法来实现的，也可以是通过算法、模型等方式来实现的。
例如，OTA升级主节点可以将一个区域内功能的多个部件划分为一个部件组，然后根据部件组内的部件(例如，域控制器DC和整车集成单元VIU等)的负载情况来确定是否把某个部件设为升级控制部件。参见图5，图5是本申请实施例提供的一种可能的部件组的结构示意图，OTA升级主节点将一个VIU及其连接的部件作为一个部件组，将VIU作为一个部件组的升级控制装置，参见区域501，第一个部件组包括图中示出的VIU1、CDC、ECU1.1、ECU1.2、ECU2.1、ECU2.2、Tbox，其中升级控制部件为VIU1；参见区域502，第二个部件组包括图中示出的VIU2、MDC、ECU3.1、ECU4.1、ECU4.2、ECU4.3、VDC，其中升级控制部件为VIU2；参见区域503，第三个部件组为VIU3、ECU5.1、ECU5.2、ECU5.3，其中升级控制部件为VIU3；参见区域504，第四个部件组为VIU4、ECU6.1、ECU6.2、ECU6.3，其中升级控制部件为VIU4。根据部件组的包含的部件和升级控制部件，可以得到如表1所示的分组信息。
表1一种分组信息
组编号 包含的部件 升级控制部件
1 VIU1、CDC、ECU1.1、ECU1.2、ECU2.1、ECU2.2、Tbox VIU1
2 VIU2、MDC、ECU3.1、ECU4.1、ECU4.2、ECU4.3、 VIU2
   VDC  
3 VIU3、ECU5.1、ECU5.2、ECU5.3 VIU3
4 VIU4、ECU6.1、ECU6.2、ECU6.3 VIU3
参见图6，图6是本申请实施例提供的又一种可能的部件组的结构示意图，OTA升级主节点将VIU或DC所连接的部件作为一个部件组，将VIU或DC作为一个部件组的升级控制装置，参见区域601，第一个部件组包括图中示出的CDC、ECU1.1、ECU1.2，其中升级控制部件为CDC；参见区域602，第二个部件组包括VIU1、ECU2.1、ECU2.2、Tbox，其中升级控制部件为VIU1；参见区域603，第三个部件组包括图中示出的MDC、ECU3.1，其中升级控制部件为VIU2；参见区域604，第四个部件组包括VIU2、ECU4.1、ECU4.2、ECU4.3；参见区域605，第五个部件组为VIU3、ECU5.1、ECU5.2、ECU5.3，其中升级控制部件为VIU3；参见区域606，第六个部件组为VIU4、ECU6.1、ECU6.2、ECU6.3，其中升级控制部件为VIU4；第七个部件组为VDC，升级控制部件即为VDC。根据部件组的包含的部件和升级控制部件，可以得到如表2所示的分组信息。
表2一种分组信息
组编号 包含的部件 升级控制部件
1 CDC、ECU1.1、ECU1.2 CDC
2 VIU1、ECU2.1、ECU2.2、Tbox VIU1
3 MDC、ECU3.1 MDC
4 VIU2、ECU4.1、ECU4.2、ECU4.3 VIU2
5 VIU3、ECU5.1、ECU5.2、ECU5.3 VIU3
6 VIU4、ECU6.1、ECU6.2、ECU6.3 VIU4
7 VDC VDC
需要说明的是，上述部件的结构、示出的ECU的编号仅作为示例，具体实现过程中还可以包括其他ECU以及其他的部件。分组信息存储的格式可以为集合(例如信息子集，对应关系集合等等)、映射表(例如关系数据库中的表)、数据表格等等，此处为了便于描述，以分组信息为数据表格形式进行说明，并不旨在限定本申请中的分组信息一定是表格形式。
可选的，部件组内的升级控制部件可以是满足一定配置条件的部件。例如升级控制部件为负载小于或者等于第一阈值的部件，再如，升级控制部件为部署有安全证书的部件。进一步可选的，OTA升级主节点还可以根据各个部件的配置确定升级控制部件，将靠近该升级控制部件的部件作为一个部件组。
在一种可能的方案中，OTA升级主节点根据部件组内的计算能力集中的控制部件(例如，域控制器DC和整车集成单元VIU)的负载情况来确定是否把某个控制部件设为升级控制部件。由于升级控制部件需要与服务器建立连接，因此若当前的节点的负载较高，则不宜被确定为升级控制部件，因此将负载的阈值确定为第一阈值。其中，第一阈值为预先定义、预先配置或者协议里预先规定的值，由于后续升级控制部件要完成升级任务，因此将负载小于或者小于第一阈值的部件确定为升级控制部件，可以减小部件的压力，使得后续的升级下载任务可以尽快完成，保证车辆的升级效率。在又一种可能的方案中，升级控制部件需要和服务器基于安全证书建立安全通道，那么部署了安全证书的部件才有资格确 定为升级控制部件。
步骤S403：OTA升级主节点向服务器发送第一消息。
具体地，第一消息用于指示车辆内至少两个部件组内的部件的版本信息。可以理解的，OTA升级主节点向服务器发送第一消息，相应的，服务器可以接收来自OTA升级主节点的第一消息，从而获取车辆内的至少两个部件组的版本信息。
可选的，第一消息中还包括车辆的标识，其中，车辆的标识可以为车辆的车辆识别号码(Vehicle Identification Number，VIN，也称为车架号码)、车辆的型号(具体可以包括厂商、型号、生产批号等等中的一个或者多个，例如benz-S350L-2020表示奔驰S350L 2020款)、车辆的集成电路卡识别码(Integrate circuit card identity，ICCID)、车辆的产品序列(Serial Number，SN)号等等中的一项或者多项。
可选的，第一消息中还包括车辆中的分组信息，该分组信息用于指示至少两个部件组。例如，分组信息可以为前述的表1或者表2。
可选的，OTA升级主节点与服务器之间收发信息的数据链路可以包括各种类型的连接介质，具体可以是有线链路(如光纤等)、或者无线链路、或者有线链路与无线链路的组合等等。例如可以为包括802.11b/g、蓝牙(Blue Tooth)、紫蜂(Zigbee)、车载短距无线通信技术、全球移动通信***(Global System for Mobile communications，GSM)、通用分组无线业务(General Packet Radio Service，GPRS)、通用移动通信***(Universal Mobile Telecommunications System，UMTS)、超宽带(Ultra Wideband，UWB)技术、车载无线传输技术等。当然，不排除还有其他技术可以用于支撑升级主节点与服务器进行通信。
步骤S404：服务器确定车辆内的至少两个部件组。
具体的，本申请各实施例中提到的服务器，可以是一个服务器、也可以是多个服务器组成的服务器集群。例如，分布式服务器可以是由多个服务器组成的服务器集群，集群中可以包括云计算服务器、内容分发网络(Content Delivery Network，CDN)服务器、网络时间协议(Network Time Protocol，NTP)、域名解析***(Domain Name System，DNS)服务器等等其中，各个服务器之间可以相互协调，共同完成计算、数据存储、通信等功能，为了方便描述，本申请实施例中将单个服务器、分布式服务器、服务器集群统称为服务器。
车辆内的至少两个部件组中的每个部件组包括一个用于控制部件组内的部件进行OTA升级的升级控制部件。服务器确定车辆内的至少两个部件组，至少有以下两种实现方式：
实现方式一：服务器从OTA升级主节点接收用于指示至少两个部件组的分组信息。例如，OTA升级主节点可以向服务器发送该用于指示至少两个部件组的分组信息，相应的，服务器接收该分组信息，从而确定至少两个部件组。再如，OTA升级主节点在第一消息中携带该用于指示至少两个部件组的分组信息，服务器接收该第一消息，解析第一消息从而确定车辆内的至少两个部件组。
实现方式二：服务器根据车辆的标识查询部件组分组信息，通过查询结果确定车辆内的至少两个部件组。由于某一个车型的车辆的部件组可以是预先配置或者预先定义好的，因此服务器可以根据车辆的标识(例如车辆的车架号、车辆的型号等)查询部件组分组信息，从而确定车辆的部件组。进一步的可选的，该部件组分组信息可以是预先配置与服务器中的，也可以是预先配置于网络侧设备中的，例如，该分组信息可以存储在数据库(具 体可以为分布式数据库)或者可以存储在网络附属存储(network attached storage，NAS)设备中，服务器向数据库或者NAS设备发送请求查询某车辆的分组信息，数据库或者NAS设备则向服务器返回查询结果，服务器根据查询结果可以确定车辆的分组信息。
步骤S405：服务器为至少两个部件组中的第一部件组生成第一升级包。
具体地，第一部件组中存在需要升级的部件，因此服务器为第一部件组生成该第一升级包。该第一升级包是将更新的数据打包(具体实现时还可以进行压缩处理等)。其中，第一部件组的升级控制部件为第一升级控制部件。
进一步的，服务器可以根据车辆内至少两个部件组的部件的版本信息，确定需要升级的部件。第一部件组中存在需要进行版本升级的部件，因此将第一部件组内需要升级的部件所需的升级数据进行打包得到该第一升级包。
需要说明的是，若车辆中存在多个部件组需要进行升级，则服务器可以为多个部件组生成多个升级包，为了方便描述，此处以第一部件组为例进行描述，并不旨在限定为一个部件组需要升级。
可选的，该车辆升级方法还包括步骤S406，具体如下：
步骤S406：服务器向OTA升级主节点发送第一下载地址。
具体的，第一下载地址用于下载第一升级包，例如，第一下载地址可以为统一资源定位符(uniform resource locator，URL)。服务器生成第一升级包后，可以为第一升级包分配第一下载地址，通过该下载地址，可以从存储该第一升级包的设备(例如，可以为多个服务器中的CDN服务器，或者NAS设备，又或者分布式数据库等)中下载该第一升级包。服务器向OTA升级主节点发送该第一下载地址，相应的，OTA接收到来自服务器的第一下载地址。
可选的，该第一下载地址具体可以包含在下载策略包中，服务器向OTA升级主节点发送下载策略包，该OTA升级主节点接受该下载策略包，从而获取该第一下载地址。进一步可选的，该下载策略包还包含有下载策略、升级条件、升级策略、升级顺序或者第一下载地址的有效时间中的一个或者多个。其中，下载策略定义了下载第一升级包的规则(例如，指定在某一时间进行下载、在供电情况满足某一条件时进行下载、是否需要通知用户确认下载等等中的一个或者多个)，升级条件指示了使用第一升级包进行升级的条件(例如，电量条件、负载条件等等中的一个或者多个)，升级策略定义了根据第一升级包进行升级的规则(例如，多个部件并行升级、串行升级、是否需要回滚、是否需要通知用户等等中的一个或者多个)，升级顺序用于指示不同部件之间升级的升级顺序(例如先升级ECU1，再升级ECU2等)，或者同一个部件多个升级程序的升级顺序(例如，先升级ECU中的***应用，再升级用户安装的应用)。进一步可选的，下载策略包中还可以包括服务器的OTA证书，用于提高数据安全性。
可选的，该第一下载地址可以经过服务器签名，则OTA升级主节点可以验证服务器签名，避免接收不可信的节点发送的下载地址，从而提高升级过程的安全性。进一步的，在第一下载地址包含在下载策略包中的情况下，服务器可以对下载策略包进行签名，则OTA升级主节点验证下载策略包的签名，在签名验证通过的情况下，才执行后续的分发下载地址等步骤。
需要说明的是，若车辆中存在多个部件组需要进行升级，则则服务器可以为多个部件组生成多个升级包，分配的下载地址相应的也有多个。为了方便描述，此处以第一下载地址为例进行描述，并不旨在限定为一个下载地址。
可选的，该车辆升级方法还包括步骤S407，具体如下：
步骤S407：OTA升级主节点向第一升级控制部件发送第一下载地址。
具体的，第一下载地址用于下载第一升级包，该第一升级包用于升级第一部件组内的部件，而第一部件组的升级控制部件为第一升级控制部件，因此OTA升级主节点向第一升级控制部件发送第一下载地址。可理解的，OTA升级主节点向第一升级控制部件发送第一下载地址，相应的，第一升级控制部件则接收来自OTA升级主节点的第一下载地址。
由于下载地址的数据大小通常是比较小的，因此先发送给升级主节点再分发对应的各组的升级控制部件，相比服务器直接与组内的升级控制部件建立连接发送下载地址，可以节省网络资源的开销、减少复杂度，从而提高升级效率。
