Description

一种基于空中下载OTA技术的升级方法及通信装置 技术领域
本申请涉及通信技术领域,尤其涉及一种基于空中下载OTA技术的升级方法及通信装置。
背景技术
随着科学技术的发展,终端设备正逐步进入人们的日常生活,人们对终端设备的智能化、安全性等要求也越来越高。通常,终端设备中部署有各种各样的软件(如应用)等。以终端设备是车辆为例,车辆中通常部署有智能座舱、传感系统、自动驾驶系统等硬件,也部署有车载操作系统、导航应用、影音播放应用等。这些软件使得终端设备的功能更加丰富,但是也更容易出现漏洞或者功能跟不上需求等,需要将原始的版本升级为更先进的版本等。因此,需要对终端设备中的软件进行升级,以更新软件版本。
目前,由于基于空中下载(over the air,OTA)技术的升级速度快、对数据的影响较小,因此已被广泛应用于智能电视、手机、平板电脑、机顶盒、车辆等的升级中。其中,OTA是一种通过无线网络进行数据下载的技术。以车辆为例来说,整车厂(original equipment manufacturer,OEM)可通过OTA技术升级车辆的中的软件,有利于厂商减少召回成本、快速响应需求、提升用户体验。
目前OTA云服务器通过OTA技术升级主要有两个层面。一是车型层面,具体的,OTA云服务器按照车型发布升级版本以及推送升级任务。二是车辆层面,具体的,OTA云服务器按照车辆跟踪升级进度,在驾驶员确认后进行升级。然而,在实际应用场景中,可能会出现多个车辆属于同一个所有者(fleet owner,FO),属于同一个所有者的这些车辆可以称为一个车队(vehicle fleet)。若仍基于上述两个层面对车辆进行升级,车辆的升级情况对车辆的所有者不可见,会导致车辆的所有者无法及时管控车辆的软件版本,从而会对车辆的管理带来风险。

需要说明的是,上述图1中所示的服务器、第一设备和第二设备的形态和数量仅用于举例,并不构成对本申请的限定。
基于上述内容,请参阅图2,为本申请提供的一种可能的应用场景示意图。该应用场景是以车队中的车辆基于OTA升级为例说明的。该应用场景中服务器以OTA云201(或称为OTA云端或OTA云服务器等)为例,第一设备202以与显示器连接的主机为例,第二设备以车辆203a、车辆203b和车辆203c为例。其中,车辆203a、车辆203b和车辆203c属于同一车队(vehicle fleet),该车队归属于第一设备202,即第一设备202用于管理车辆203a、车辆203b和车辆203c,该第一设备202可称为车队(或车辆)所有者。OTA云201与第一设备202可通过移动通信网络(例如2G/3G/4G/5G/未来6G等网络)、或WLAN或通过短距通信技术等进行通信,本申请对第一设备和OTA云的通信方式不作限定。进一步,OTA云与车辆203a、车辆203b、车辆203c和车辆203d也可通过移动通信网络(例如2G/3G/4G/5G/未来6G等网络)、或WLAN或短距通信技术等进行通信。进一步,第一设备202与车辆203a、车辆203b、车辆203c和车辆203d也可通过移动通信网络(例如2G/3G/4G/5G/未来6G等网络)、或WLAN或短距通信技术等进行通信。
其中,车辆(如车辆203a、车辆203b和车辆203c)包括可以进行软件升级的任意形式的车辆。例如,智能车、电动车、数字汽车、轿车、卡车、摩托车、公共汽车、割草机、娱乐车、游乐场车辆、施工设备、电车、或高尔夫球车等,本申请对此不作限定。图2以 车辆203a为例,车辆中至少包括网关(gate way,GW)、用于支撑智能驾驶的软硬件一体化平台即车载计算平台(vehicle computing platform)例如移动数据中心(mobile data center,MDC)、人机交互系统(human-machine interaction,HMI)、远程信息控制单元(telematics control unit,TCU)、汽车盒子(telematics box,Tbox)、电子控制单元(electronic control unit,ECU)等中的一个或多个部件。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)、多媒数据传输(media oriented system transport,MOST)网络等网络数据在不同网络中进行路由。MDC是车辆的智能车载计算平台,MDC可以用于实现车辆的自动驾驶功能。HMI是车辆的信息娱乐系统。TCU和Tbox主要用于和车辆外部设备(例如云端、车队所有者等)、后台系统等进行通信。ECU是车辆专用微机控制器,ECU包括但不限于整车集成单元(vehicle integrated/intergration unit,VIU)、座舱域控制器(cockpit domain controller,CDC)和整车域控制器(vehicle domain controller,VDC)等。需要说明的是,本申请中需要升级的可以包括但不限于上述GW、MDC、HMI、TCU、Tbox和ECU中任一项或任多项;还可以包括操作系统、导航软件、地图软件、监控软件等。
OTA云是基于OTA升级过程中与车辆进行信息交互的服务器。通常OTA云可以是提供基于OTA升级的服务器,例如可以与软件开发设备通过互联网协议(internet protocol,IP)网络建立连接,从而获取需要升级的软件包,并将软件包发送给需要升级的车辆。进一步,还可以指示车辆需要对哪些软件进行升级。示例性地,OTA中存储有各个车辆标识码和软件版本信息。一般情况下,OTA云可由OEM管理。第一设备可以是用于管理车队的主机,该主机可以与显示器连接。
进一步,在一种可能的实现方式中,在车辆的GW中可部署有OTA主模块(或称为OTA master模块或升级主模块),在其它部件中部分有OTA从模块(或称为OTA slave模块或对应部件的升级从模块)。OTA主模块可以用于协调各个部件的OTA从模块执行升级任务。具体的,GW中的OTA主模块接收OTA云发送的升级包,将其分发给OTA从模块,使得OTA从模块指挥车辆内的其它部件安装和激活升级包,完成对车辆中的一个或者多个部件的升级。可以理解的是,OTA主模块也可以部署于TCU模块、或Tbox模块。
可以理解的是,上述图2中所示的OTA云、第一设备和车辆的形态和数量仅用于举例,并不构成对本申请的限定。
需要说明的是,上述所描述的系统架构和应用场景是为了更加清楚的说明本申请的技术方案,并不构成对本申请提供的技术方案的限定。例如,本申请中基于OTA升级的方法还可应用于智能电视、智能手机、平板电脑、机顶盒等设备的升级场景中。
如背景技术所描述,由于属于同一车队的车辆的使用者和所有者通常是不同的,因此,车辆的升级情况对车辆的所有者是不可见的,如此,会导致车辆的所有者无法及时管控车辆的软件版本,从而会对车辆的管理带来风险。
鉴于上述问题,本申请提供一种基于OTA升级的方法。该基于OTA升级的方法可以使得车队的所有者及时管控车队中的车辆的升级情况,从而提高车辆管理的安全性。
本申请提供的基于OTA升级的方法可应用于上述图1所示的通信系统中,下文介绍的基于OTA升级的方法中的OTA云可以是上述图1中的服务器101,第一设备可以是上述图1中的第一设备102,车队中的车辆可以上述图1中的第二设备103a、第二设备103b或第二设备103c。或者,也可以应用于上述图2所示的应用场景中,其中,OTA云可以是 上述图2中的OTA云201,第一设备可以是上述图2中的第一设备202,车队中的车辆可以上述图2中的车辆203a、车辆203b或车辆203c。
基于上述内容,下面结合附图3至附图12,对本申请提出的基于OTA技术的升级方法进行具体阐述。
如图3所示,为本申请提供的一种基于OTA技术的升级方法的方法流程示意图。该方法可包括以下步骤:
步骤301,第一设备向OTA云发送车队信息。相应的,OTA云接收来自第一设备的车队信息。
其中,第一设备用于管理车队,车队包括至少两辆车辆,车队信息包括属于同一车队的车辆的车辆标识。示例性的,车辆标识可以包括但不限于车辆的唯一标识码(vehicle identification number,VIN)。结合上述图2,车队信息可包括车辆203a的车辆标识、车辆203b的车辆标识和车辆203c的车辆标识。进一步,在一种可选的实现方式中,车队信息还可包括车队标识。

步骤302,OTA云根据来自第一设备的车队信息和第一车辆标识,确定第一目标车辆。
该步骤302为可选步骤。
其中,第一车辆为OTA云获取的需要升级的车辆,第一车辆标识为第一车辆的车辆标识。第一目标车辆与车队信息和第一车辆相关,具体的,第一目标车辆可以是OTA云基于车队信息和第一车辆确定的车队信息所对应的车队中需要升级的车辆。
在一种可能的实现方式中,OTA云确定有N辆第一车辆需要升级,一辆第一车辆对应一个第一车辆标识。也可以理解为,OTA云确定N个第一车辆标识对应的N个第一车辆需要升级,N为正整数。示例性地,当车辆的软件存在漏洞(即需要进行漏洞修复)、需要增加新的功能、安全防护需要升级、或架构需要升级等,OTA云可确定该车辆需要升级,进而可生成对应的升级包。
进一步,在一种可选的实现方式中,OTA云可确定第一车辆标识所属的车队标识,并确定车队信息包括的车队标识是否与第一车辆标识所属的车队标识相同,若相同,OTA云 可用第一车辆标识逐一匹配车队信息中的车辆标识,将车队信息中的车辆标识与第一车辆标识相同的车辆标识对应的车辆确定为第一目标车辆。示例性地,OTA云可基于车队信息和N个第一车辆标识,确定出M辆第一目标车辆,M为小于或等于N的正整数。
示例性地,OTA中可以预先存储车队标识与车辆标识的对应关系。进一步,OTA云还可为对应的每个车队创建账号,并将车队对应的账号、车队标识和车队中包括的车辆(例如第一车辆)的车辆标识(如第一车辆标识)进行存储。可以理解的是,第一设备可以预先获取到所管理的车队的车队信息,例如可以是用户输入的。
步骤303,OTA云向第二目标车辆发送第一升级任务信息。相应的,第二目标车辆接收来自OTA云的第一升级任务信息。
其中,第一升级任务信息包括升级包。第二目标车辆为第一设备从第一目标车辆中确定的至少一辆,可能的确定方法可参见下述方法1和方法2的介绍,此处不再赘述。
进一步,可选地,第一升级任务信息还可包括升级类型,升级类型可以包括但不限于:已确认升级(即第一设备已确认可以直接升级)、静默(无需通知用户直接升级)、常规(用户同意后升级)和强制(通知用户后无需用户同意直接升级)等;其中,用户例如可以是使用第二目标车辆的驾驶员等。
通过上述步骤301至步骤303可以看出,第一设备向OTA云发送车队信息,可以使得OTA云获得属于同一车队的车辆的车辆标识,从而可向第一设备确定出的需要升级的第二目标车辆发送第一升级任务信息。
在上述步骤301之前,OTA云与第一设备之间也可以预先建立安全通道(或称为安全通信)。示例性地,在第一设备向OTA云发送车队信息之前,可以进行一些配置,比如配置证书、私钥等。基于配置的信息,OTA云与第一设备之间可建立安全通道。其中,安全通道例如可以包括但不限于:基于安全套接字层的超文本传输协议(hyper text transfer protocol over secure socket layer,HTTPS)、或者数据包传输层安全性协议(datagram transport layer security,DTLS)等的安全通道中的一个或多个,本申请对安全通道的类型不作限定。通过在OTA云与第一设备之间的安全通道,有助于避免第一设备与OTA云之间交互的信息(如车队信息等)或数据等泄露、被篡改或被破坏等。
在上述步骤303之前,OTA云与车队中的车辆(如第二目标车辆)之间也可以预先建立安全通道。具体可参见上述OTA云与第一设备之间建立的安全通道。通过在OTA云和车队中的车辆之间的安全通道,有助于避免在车队中的车辆与OTA云之间交互的信息(如第一升级任务信息等)或数据等泄露、被篡改或破坏等。
基于上述图3的内容,下面示例性的示出了三种可能的确定第二目标车辆的方法。

请参阅图4,为本申请提供的一种第一设备确定第二目标车辆的方法流程示意图。该方法包括以下步骤:
步骤401,OTA云向第一设备发送第一请求消息。相应地,第一设备接收来自OTA云的第一请求消息。
其中,第一请求消息用于请求第一设备从第一目标车辆中确定允许升级的第二目标车辆。示例性地,第一请求消息包括第一目标车辆的车辆标识。
进一步,在一种可选的实现方式中,第一请求消息还可包括升级任务的关联信息,其 中,升级任务的关联信息包括升级需要的时长、升级的目的或升级后的变化等中的至少一项。
进一步,在一种可选的实现方式中,升级任务的关联信息还可包括升级条件、升级顺序、用户通知策略、以及升级包大小等。其中,升级条件可以保证车辆成功下载到升级包。升级条件例如可以包括:车辆不处于以下一种或多种状态:紧急事件处理状态、发动机处于工作状态、存储空间不足、剩余流量低于预设流量阈值等。升级顺序可以表示不同部件升级的时间先后顺序。升级包的大小一般为几兆(M)到十几M。
需要说明的是,上述升级类型也可以属于升级任务的关联信息中的一项。
步骤402,第一设备根据第一请求消息,将第一目标车辆中的至少一辆确定为第二目标车辆。
可以理解的是,第一目标车辆的数量大于或等于第二目标车辆的数量。
在一种可能的实现方式中,第一设备可整体将全部的第一目标车辆均确定为允许升级的第二目标车辆。
在另一种可能的实现方式中,第一设备可将第一目标车辆中的部分确定为允许升级的第二目标车辆。
在又一种可能的实现方式中,第一设备可以根据升级需要的时长、升级的目的或升级后的变化等中的至少一项,从第一目标车辆中确定出允许升级的第二目标车辆。
需要说明的是,上述给出的第一设备从第一目标车辆中确定允许升级的第二目标车辆的可能的实现方式仅是示例,本申请对此不作限定。
当第一设备确定出第二目标车辆后,可通过如下三种可能的方案通知OTA云。方案1执行下述步骤403;方案2执行下述步骤404至步骤406;方案3执行下述步骤407至步骤408。
步骤403,第一设备向OTA云发送第一响应消息。相应的,OTA云接收来自第一设备的第一响应消息。
也可以理解为,第一设备直接向OTA云发送第一响应消息。
其中,第一响应消息可包括第二目标车辆的信息。也可以理解为,第一响应消息可包括从第一目标车辆中选择的允许升级的第二目标车辆的相关信息。例如,第一响应消息包括第二目标车辆标识。需要说明的是,第二目标车辆的信息也可以是其它可能的信息,例如可以是预先约定的任意形式的信息,本申请对此不作限定。
步骤404,第一设备向允许升级的第二目标车辆发送第二指示信息。相应地,第二目标车辆接收来自第一设备的第二指示信息。
其中,第二指示信息可以用于指示是否允许该第二目标车辆升级或可以用于指示允许第二目标车辆升级。第二指示信息的具体形式可以是第一设备与第二目标车辆预先约定的,例如,第二指示信息为“1”表示允许该第二目标车辆升级,或者第二指示信息为第二目标车辆的标识等。需要说明的是,第二指示信息的具体内容也可以是第一设备通知给第二目标车辆的,本申请对此不作限定。
此处,若第一设备确定出的第二目标车辆为多辆时,第一设备可以向多辆第二目标车辆中的每一辆发送第二指示信息。
步骤405,第二目标车辆根据第二指示信息生成第一响应消息。
关于第一响应消息的介绍可参见前述步骤403的介绍,此处不再赘述。
步骤406,第二目标车辆向OTA云发送第一响应消息。相应地,OTA云接收来自第二目标车辆的第一响应消息。
步骤407,第一设备向第二目标车辆发送第一响应消息。相应的,第二目标车辆接收来自第一设备的第一响应消息。
此处,若第一设备确定出的第二目标车辆为多辆时,第一设备可以向多辆第二目标车辆中的每一辆发送第一响应消息。
步骤408,第二目标车辆向OTA云发送第一响应消息。
上述步骤407和步骤408也可以理解,第二目标车辆用于透传第一设备的第一响应消息。
通过上述步骤401至步骤408,通过第一请求消息中携带的升级任务的关联信息,可以使得第一设备根据实际情况灵活选择允许升级的第一目标车辆。而且,第一设备可从第一目标车辆中批量的确定出允许升级的第二目标车辆,有助于简化第一设备管理车队。
方法2
请参阅图5,为本申请提供的另一种第一设备确定第二目标车辆的方法流程示意图。该方法包括以下步骤:
步骤501,OTA云向第一目标车辆发送第一指示信息。相应地,第一目标车辆接收来自OTA云的第一指示信息。
其中,第一指示信息用于指示第一目标车辆向第一设备请求确认是否允许升级。
在一种可能的实现方式中,第一指示信息包括第一设备的地址。例如,可以是统一资源定位符(uniform resource locator,URL)链接,该URL链接可以链接到第一设备的网页或应用(application,APP)。如此,可以使得第一目标车辆准确且快速的确定出第一设备。
步骤502,第一目标车辆根据第一指示信息,向OTA云发送第二请求消息。相应地,OTA云接收来自第一目标车辆的第二请求消息。
其中,第二请求消息用于向第一设备请求确定是否允许第一目标车辆升级。示例性地,第二请求消息包括第一目标车辆的车辆标识。
进一步,在一种可选的实现方式中,第一指示信息还包括升级任务的关联信息,升级任务的关联信息可以包括但不限于升级需要的时长、升级的目的或升级后的变化中的至少一项。其中,升级任务的关联信息可用于第一目标车辆确定是否向OTA云发送第二请求消息。
示例性地,第一目标车辆接收到第一指示信息后,可根据第一指示信息包括的升级任务的关联信息,确定是否向OTA云发送第二请求消息。例如,第一目标车辆确定当前是否处于以下一种或多种状态:紧急事件处理状态、发动机处于工作状态、存储空间不足、剩余流量低于预设流量阈值等。当第一目标车辆确定当前状态为以上状态中的任一种或任多种时,可暂时不向OTA云发送第二请求消息。再比如,第一目标车辆确定当前不处于以上任一种状态时,向OTA云发送第二请求消息。
在一种可能的实现方式中,第二请求消息中还可携带升级任务的关联信息,以便于第一设备根据升级任务的关联信息确定是否允许发送该第二请求消息的第一目标车辆升级。
步骤503,OTA云向第一设备转发第二请求消息。相应地,第一设备接收来自OTA云的第二请求消息。
一种可能的实现方式,OTA云向第一设备透传第二请求消息。另外一种可能的实现方 式中,OTA云可以对第二请求消息进行处理之后向第一设备转发,但是第二请求消息的功能或指示的含义不变。例如,若OTA云与第一目标车辆、OTA云与第一设备之间的通信协议不同时,OTA云对第二请求消息进行处理可以是进行协议的转换。本申请对OTA转发第二请求消息的具体实现不作限定。步骤504,第一设备根据第二请求消息,将第一目标车辆确定为第二目标车辆。
在一种可能的实现方式中,第一设备直接确定允许发送第二请求消息的第一目标车辆升级。也可以理解为,第一设备可直接将发送第二请求消息的第一目标车辆确定为第二目标车辆。
在另一种可能的实现方式中,第一设备可根据第二请求消息中携带的升级任务的关联信息,确定是否允许发送该第二请求消息的第一目标车辆升级。
示例性地,对于第一设备来说,发送第二请求消息的可以是一辆第一目标车辆,若第一设备确定允许发送该第二请求消息的第一目标车辆升级,即相当于将发送该第二请求消息的第一目标车辆确定为了第二目标车辆。
步骤505,第一设备向OTA云发送第二响应消息。相应的,OTA云接收来自第一设备的第二响应消息。
其中,第二响应消息包括第二目标车辆的信息。在一种可能的实现方式中,第二响应消息可直接包括第二目标车辆的信息,例如,第二响应消息包括第二目标车辆的车辆标识。在另一种可能的实现方式中,第二响应消息可包括第三指示信息,第三指示信息用于指示第二目标车辆的信息。需要说明的是,第三指示信息可以是预先约定的任意形式的信息,本申请对此不作限定。

通过上述方法2或方法3,第一目标车辆可根据第一指示信息,触发第一设备确认是 否允许第一目标车辆进行升级,不需要再通过HMI提示或征求驾驶员的确认,从而有助于减轻驾驶员的负担。而且,由第一设备决策允许哪些第一目标车辆升级,有助于提高对车队中的车辆管理的安全性。
当第二目标车辆接收到第一升级任务后,可基于第一升级任务信息进行升级,并与第一设备和OTA同步升级结果。
如图7所示,为本申请提供的一种第二目标车辆升级的方法流程示意图。该方法包括以下步骤:
步骤701,第二目标车辆根据第一升级任务信息进行升级。
在一种可能的实现方式中,第一升级任务信息还可包括升级类型,若第二目标车辆确定升级类型为已确认升级后,可以基于接收到的第一升级任务信息包括的升级包按照OTA的升级流程进行升级,不需要第二目标车辆的使用者(或称为驾驶员)确认,从而可减轻驾驶员的负担。
在另一种可能的实现方式中,若第二目标车辆确定升级类型不是已确认升级,可通过人机交互系统HMI提示该第二目标车辆的使用者确认是否进行升级;若检测到第二目标车辆的使用者确认进行升级,第二目标车辆可基于接收到的第一升级任务信息包括的升级包进行升级。
在第二目标车辆完成升级后,可通过如下两种可能的方案将升级结果同步给第一设备和OTA云。其中,方案A包括步骤702至步骤703;方案B包括步骤704至步骤705。
步骤702,第二目标车辆向OTA云发送升级结果。相应地,OTA云接收来自第二目标车辆的升级结果。
其中,升级结果可以包括但不限于升级成功、升级失败、回滚成功或回滚失败。具体的,若第二目标车辆升级成功,向OTA云发送升级成功的升级结果。若第二目标车辆升级失败,向OTA云发送升级失败的升级结果。进一步,在一种可选的实现方式中,若第二目标车辆升级失败,为了尽可能的减小对车辆正常使用的影响,可以进行回滚。基于此,若回滚成功,第二目标车辆可向OTA云发送回滚成功的升级结果;若回滚失败,第二目标车辆可向OTA云发送回滚失败的升级结果。
示例性地,升级结果的具体形式可以是第二目标车辆和OTA云预先约定的。例如,1表示升级成功,0表示升级失败,10表示回滚成功,00表示回滚失败。或者,升级结果的具体形式可以是第二目标车辆指示给OTA云的。本申请对升级结果的具体形式不作限定。
进一步,可选地,升级结果中还可包括第二目标车辆的信息。例如,升级结果中还可包括第二目标车辆的车辆标识。再比如,升级结果中还可包括第三指示信息,第三指示信息用于指示第二目标车辆的信息。如此,以便于OTA和第一设备可以快速的确定出是哪个第二目标车辆的升级结果。

步骤703,OTA云向第一设备发送升级结果。相应地,第一设备接收来自OTA云的升级结果。
也可以理解为,OTA云接收到来自第二目标车辆的升级结果后,及时同步给第一设备。
步骤704,第二目标车辆向第一设备发送升级结果。相应地,第一设备接收来自第二 目标车辆的升级结果。
该步骤704可参见上述步骤702的介绍,具体可将上述步骤702中的“OTA云”用“第一设备”替换,此处不再重复赘述。
步骤705,第一设备向OTA云发送升级结果。相应地,OTA云接收来自第一设备的升级结果。
换言之,第一设备接收到来自第二目标车辆的升级结果后,及时同步给OTA云。

需要说明的是,上述给出的两种加密方式仅是示例,也可以采用其它可能的加密方式,本申请对此不做限定。
在一种可能的实现方式中,第三升级任务信息还可包括升级任务的关联信息,关于升级任务的关联信息可参见前述相关介绍,此处不再赘述。

在又一种可能的实现方式中,若第三升级任务信息中还包括升级任务的关联信息,第一设备可以根据升级任务的关联信息,从第三升级任务信息中包括的第一目标车辆标识对应的第一目标车辆中确定出允许升级的第二目标车辆。
需要说明的是,上述给出的第一设备从第一目标车辆中确定允许升级的第二目标车辆的可能的实现方式仅是示例,本申请对此不作限定。
步骤1105,第一设备向第二目标车辆发送第四升级任务信息。相应的,第二目标车辆接收来自第一设备的第四升级任务信息。
其中,第四升级任务信息与第三升级任务信息相关。一种示例中,第四升级任务信息与第三升级任务信息相同。另一种示例中,第四升级任务信息是根据第三升级任务信息的得到的。例如,第四升级任务信息包括第一设备对接收到的升级包进行数字签名后得到的信息。通过对第三升级任务信息包括的升级包进行数字签名,可以进一步提高第一设备和第二目标车辆之间通信的安全性。
在一种可能的实现方式中,第四升级任务信息还可包括升级类型,升级类型为已确认升级。
示例性地,在第二目标车辆根据第四升级任务信息完成升级后,可与第一设备和OTA同步升级结果。可参见上述图7的介绍,此处不再赘述。
通过上述步骤1101至步骤1105可以看出,第一设备向OTA云发送车队信息,可以使 得OTA云获得属于同一车队的车辆的车辆标识;进一步向第一设备发送包括第一目标车辆的车辆标识的第三升级任务信息,可以使得第一设备确定允许哪些第一目标车辆升级,进而有助于提高对车队中的车辆管理的安全性。
上述实施例可以适用于第一设备可与其管理的车队中的车辆直接通信的场景。进一步,可选地,为了实现车队中的车辆与第一设备直接通信,车队中的至少一辆车辆部署有车队代理,其它车辆部署有OTA代理,部署有车队代理的车辆可与第一设备直接通信,部署有OTA代理的车辆可与部署有车队代理的车辆直接通信。可以理解的是,部署有OTA代理的第二目标车辆可以理解为OTA的客户端,OTA云可以理解为OTA的服务端。其中,车队代理可以包括部署在车端且可以与第一设备和/或OTA云交互的软件。OTA代理可以包括基于OTA升级的软件,例如支持OTA升级的软件,或者实现OTA升级的软件。

该步骤1202为可选步骤。
示例性地,第一设备在向部署有车队代理的第二目标车辆发送升级包之前,可先对升级包进行数字签名。部署有车队代理的第二目标车辆在接收到数字签名的升级包后,先验证升级包的数字签名,在数字签名验证通过之后,再进行后续处理。这样,有助于提高升级包的安全性,降低升级出错的可能性。
步骤1203,部署有车队代理的第二目标车辆向部署有OTA代理的第二目标车辆发送第四升级任务信息。
步骤1204,部署有OTA代理的第二目标车辆根据第四升级任务信息进行升级。
其中,第四升级任务信息还包括已确认升级的升级类型。
在一种可能的实现方式中,部署有OTA代理的第二目标车辆确定升级类型为已确认升级后,可以直接按照OTA的升级流程进行升级,不需要驾驶员确认。
步骤1205,部署有OTA代理的第二目标车辆向部署有车队代理的第二目标车辆发送升级结果。相应地,部署有车队代理的第二目标车辆接收来自部署有OTA代理的第二目标车辆的升级结果。
该步骤1205中的升级结果可参见前述相关介绍,此处不再赘述。
进一步,部署有车队代理的第二目标车辆、第一设备以及OTA云三者之间同步升级结果的过程可参见前述图7的介绍,此处不再赘述。
示例性地,第一设备与车队中的车辆建立安全通道,可以是第一设备与部署有车队代理的第二目标车辆建立安全通道。可以理解的是,为了实现上述实施例中功能,通信装置包括了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到,结合本申请中所公开的实施例描述的各示例的模块及方法步骤,本申请能够以硬件或硬件和计算机软件相结合的形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行,取决于技术方案的特定应用场景和设计约束条件。
