具体实施方式
下面将结合附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
除非上下文另有要求，否则，在整个说明书和权利要求书中，术语“包括(comprise)”及其其他形式例如第三人称单数形式“包括(comprises)”和现在分词形式“包括(comprising)”被解释为开放、包含的意思，即为“包含，但不限于”。在说明书的描述中，术语“一个实施例(one embodiment)”、“一些实施例(some embodiments)”、“示例性实施例(exemplary embodiments)”、“示例(example)”、“特定示例(specific example)”或“一些示例(some examples)”等旨在表明与该实施例或示例相关的特定特征、结构、材料或特性包括在本公开的至少一个实施例或示例中。上述术语的示意性表示不一定是指同一实施例或示例。此外，所述的特定特征、结 构、材料或特点可以以任何适当方式包括在任何一个或多个实施例或示例中。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在描述一些实施例时，可能使用了“耦接”和“连接”及其衍伸的表达。例如，描述一些实施例时可能使用了术语“连接”以表明两个或两个以上部件彼此间有直接物理接触或电接触。又如，描述一些实施例时可能使用了术语“耦接”以表明两个或两个以上部件有直接物理接触或电接触。然而，术语“耦接”或“通信耦合(communicatively coupled)”也可能指两个或两个以上部件彼此间并无直接接触，但仍彼此协作或相互作用。这里所公开的实施例并不必然限制于本文内容。
“A、B和C中的至少一个”与“A、B或C中的至少一个”具有相同含义，均包括以下A、B和C的组合：仅A，仅B，仅C，A和B的组合，A和C的组合，B和C的组合，及A、B和C的组合。
“A和/或B”，包括以下三种组合：仅A，仅B，及A和B的组合。
如本文中所使用，根据上下文，术语“如果”任选地被解释为意思是“当……时”或“在……时”或“响应于确定”或“响应于检测到”。类似地，根据上下文，短语“如果确定……”或“如果检测到[所陈述的条件或事件]”任选地被解释为是指“在确定……时”或“响应于确定……”或“在检测到[所陈述的条件或事件]时”或“响应于检测到[所陈述的条件或事件]”。
本文中“适用于”或“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
另外，“基于”的使用意味着开放和包容性，因为“基于”一个或多个所述条件或值的过程、步骤、计算或其他动作在实践中可以基于额外条件或超出所述的值。
以下，对本申请实施例涉及的名词进行解释，以方便读者理解。
空中下载技术(over the air technology，OTA)：是一种通过移动通信的空中接口对用户身份识别卡(subscriber identity module，SIM)卡数据及应用进行远程管理的技术。空中接口可以采用无线应用协议(wireless application protocol，WAP)、通用分组无线服务(general packet radio service，GPRS)、第三代移动通信技术(3rd-Generation，3G)、第四代移动通信技术(4rd-Generation，4G)、第五代移动通信技术(5rd-Generation，5G)及短消 息技术，以及非公网的点对点传输。
OTA技术的应用，使得移动通信不仅可以提供语音和数据服务，而且还能提供新业务下载。这样一来，应用及内容服务商可以不受平台的局限，不断开发出更具个性化的贴近用户需求的服务，如信息点播、互动娱乐、位置服务以及银行交易等服务。通过OTA技术，用户只需要对手机进行简单操作(如点击下载某个应用程序)，响应于用户的操作，手机就可以向能够提供应用程序的安装数据的服务器发送用于请求获取应用程序的安装数据的请求信息。后续，手机在接收到来自服务器的安装数据之后，就可以解析该数据，进而完成应用程序的安装，满足了用户的需求。由此可见，基于OAT技术，可以实现从网络获取与用户所需要的各种业务数据。当然，OTA技术还可以根据用户的意愿定制具体业务。
OTA技术还可以应用在多个技术领域，比如，智能家电领域、车联网领域。当OTA技术应用于车联网领域时，可以实现车辆的软件更新。其中，车辆的软件更新可以包括车辆的固件升级。具体的，固件升级，指的是对车辆的设备的内嵌固件的升级。该设备可以为音乐播放设备、视频播放设备、导航设备、主控设备等便携式设备。基于固件的升级，可以实现对车辆终端的系统性能进行完成，以及增强车辆终端的系统稳定性、修补车辆终端的系统漏洞等。
一种示例中，车辆可以通过OTA技术下载固件对应的固件包，并根据该固件包实现固件的升级。
固件通常指担任着一个系统最基础、最底层工作的软件(为了统一描述，后续统称为软件)，随着计算机技术的不断发展，固件与一般的应用程序的区别已经越来越小。也即，在一些描述中，可以将固件作为应用程序。
固件包通常指系统的镜像压缩包。车辆在进行固件升级时，可以将固件包直接解压缩处理，得到新的固件的安装数据。如此，车辆可以使用该安装数据替换原来固件的安装数据，以完成固件升级。
随着智能网联技术在车辆上的应用，车辆的软件的更新速度在不断加快。从近些年的车辆召回问题来看，如今的车辆召回的原因已从传统的硬件故障延展到了系统程序和软件的设计问题。
一种可能的实现方式中，当车辆的软件需要更新时，车辆可以由技术人员通过维护设备或存储器(如硬盘、U盘、光谱等)对车辆进行软件升级操作。比如，利用维护设备接入车载自诊断系统(on-board diagnostics，OBD)接口进行软件版本的检测。若车辆的软件与更新后的软件不同(比如，车辆 当前安装的软件的版本信息与更新后的版本信息不同)，车辆可以响应于技术人员的更新操作，从维护设备中获取到更新后的软件的安装数据，并根据该安装数据对车辆的软件进行更新。其中，更新操作可以是指技术人员从软件的多个版本信息中选择与车辆匹配的版本信息的操作。
其中，维护设备可以是指配置有更新后的软件的安装数据的设备。例如，维护设备可以包括计算机、平板电脑、手机等。
在一些场景下，当技术人员使用存储器对车辆的软件升级时，存储器可以配置有更新后的软件的安装数据。车辆具有接入/安装存储器的接口，例如，车辆可以具有光驱。当车辆通过该光驱读取存储器中的数据时，车辆可以对比该存储器中的软件的版本信息与车辆的软件当前的版本信息是否一致。若不一致，则车辆可以进行软件升级。若一致，则车辆可以不进行软件升级。
具体的，如图1所示，维护设备配置的软件的版本可以包括软件版本1～软件版本n。n为正整数。图1示出了一种车辆软件的升级方案。厂家对车辆软件进行升级后，会通知用户到指定地点由专业的技术人员进行升级处理。用户车辆到达指定地点后，技术人员将维护设备与车辆连接。进一步，技术人员将车辆当前的软件版本与维护设备中最新的软件版本进行对比，若车辆当前的软件版与最新的软件版本不同，则对车辆进行软件升级。
其中，维护设备可以接入车辆上的OBD接口，实现与车辆的连接。OBD接口可以包括通用串行总线(universal serial bus，USB)接口、RS-485通信接口、DB9串口连接接口等。另外，在维护设备为光盘的情况下，维护设备还可以通过放置到车辆的光驱中，与车辆进行连接。
一些实施例中，当车辆完成软件升级之后，可以输出升级完成的消息。例如，可以通过语音播报的方式输出该消息。或者，在车辆具有显示器的情况下，可以通过显示器显示该消息。
可见，上述方式对车辆软件的升级与维护，需要用户驾驶车辆到达指定地点，由专业的技术人员来完成。这样一来，使得升级车辆软件较为繁琐、升级效率低下。同时，在车辆距离指定地点较远时，需要浪费用户的时间，且若需要升级的软件与驾驶安全相关，给用户带来了驾驶风险。因此，降低了用户的体验。
鉴于此，本申请实施例提供了一种基于OTA方式的软件更新方法，应用于车辆。该方法包括：车辆在接收用于指示上报软件的版本信息的指示消息后，可以向当前建立连接的控制节点上报车辆配置的软件的当前版本信息。控制节点可以在车辆配置的软件当前版本与升级的软件的版本信息不一致的 情况下，向车辆发送用于指示软件升级后的版本信息的消息。这样一来，车辆可以根据该消息下载升级后的软件的更新数据，并对该软件进行升级。比如，车辆在移动过程中，接收到来自控制节点发送软件的更新数据的下载链接，车辆便可以根据该下载链接下载软件的更新数据，进而根据下载的更新数据进行更新。如此，车辆可以及时更新软件，提高了用户的体验。
需要说明的是，本申请实施例中，车辆可以是指车辆终端，或者可以是指车辆中安装有软件的设备。
下面结合附图对本申请实施例提供的方法进行详细说明。
图2示出了本申请实施例提供的一种网络架构的示意图。如图2所示，该网络架构可以包括车辆(如车辆1、车辆2)以及控制节点(如移动终端、服务器、车辆3)。其中，车辆可以与控制节点通信连接。例如，当控制节点为服务器或移动终端时，车辆可以通过移动通信网络(例如2G/3G/4G/5G网络)与控制节点进行通信，也可以通过无线局域网络(wireless local area networks，WLAN)、蓝牙与控制节点进行通信。又例如，当控制节点为其他车辆时，车辆之间可以通过车用无线通信技术(vehicle to x，V2X)通信连接。本申请实施例对车辆与控制节点之间的通信方式不作限定。
需要说明的，控制节点中存储有目标软件的更新后的版本信息。控制节点可以用于向车辆发送指示车辆上报目标软件的版本信息的消息。
其中，移动终端可以为UE或者移动台(mobile station，MS)或者移动终端(mobile terminal，MT)等。具体的，移动终端可以是手机(mobile phone)、平板电脑、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)或带无线收发功能的电脑。
服务器可以为云服务器、OTA服务器，也可以为服务器集群。服务器可以是单独的一个服务器，或者，也可以是由多个服务器构成的服务器集群。部分实施方式中，服务器集群还可以是分布式集群。本申请实施例对服务器的具体实现方式也不作限制。
其中，车辆用于向控制节点发送自身配置的目标软件的当前版本信息。进一步的，控制节点还用于向车辆发送第二指示信息，以指示目标软件更新后的版本信息。相应的，车辆用于根据第二指示信息，更新目标软件。
在实际应用中，控制节点可以为移动终端、服务器、车辆等。在控制节点为车辆的情况下，该车辆存储有目标软件更新后的版本信息，该车辆可以作为控制节点向其他车辆发送第一指示信息。
车辆可以包括通信模块，以实现与控制节点的通信。通信模块包括天线、射频前端、模数转换器(analog to digital converter，ADC)、数模转换器(digital to analog converter，DAC)以及专用集成电路(application specific integrated circuit，ASIC)。
其中，天线可以包括发射天线和接收天线。发射天线可以用于发送信号，接收天线可以用于接收信号。发射天线和接收天线可以为同一天线，也可以为不同的两个天线。在发射天线和接收天线为同一天线的情况下下，该天线作为发射或接收的基本特性参数是相同的，即天线的互易定理。
射频前端可以用于对射频信号进行过滤和放大。射频前端中主要器件包括：功率放大器(power amplifier，PA)、滤波器(filter)、开关(switch)、低噪音放大器(low noise amplifier，LNA)、调谐器(tuner)、双/多工器(du/multiplexer)。为了使射频前端的尺寸更小，上述器件可以集成在一个电路中，形成射频集成电路(radio frequency integrated circuit，RFIC)。
ADC用于将模拟信号转变为数字信号。例如，ADC可以为AD芯片。
DAC用于将数字信号转变为模拟信号。例如，DAC可以为DA芯片。
在一些实施例中，ADC和DAC可以集成在一个芯片上，如，AD与DA芯片。
专用集成电路，可以为芯片(如人工智能(artificial intelligence，AI)芯片)。AI芯片可以为现场可编程逻辑门阵列(field programmable gate array，FPGA)，以提高数据信号的处理速度。FPGA可分为处理系统(processing system，PS)部分以及可编程逻辑(progarmmable logic，PL)部分。其中，PS就是与FPGA无关的ARM处理器(advanced risc machines)的系统级芯片(system on chip，SOC)的部分；PL就是FPGA部分。在实际应用中，车辆的FPGA的型号可以根据需要配置。例如，车辆可以配置型号为FMQL45T900的FPGA。可以理解的，采用FPGA作为专用集成电路，可以提高车辆的通信模块的处理速度。
如图3所示，当通信模块中信号的处理过程可以包括：FPGA在接收到初始信号之后，对该初始信号进行处理，得到数字信号，并向DAC传输该数字信号；DAC在接收到来自数字信号之后，将该数字信号转变为模拟信号；然后，模拟信号经射频前端放大后由发射天线发出。
如图4所示，当车辆接收控制节点发送的信号时，模拟信号由天线接收并传递至射频前端，射频前端对接收到的模拟信号进行降噪处理后经过ADC，转变为数字信号，再传输至FPGA进行处理。
在实际应用中，可以采用高速率的AD与DA芯片YA14D170/210/250，作为通信模块中的ADC与DAC，即将ADC与DAC集成于芯片YA14D170/210/250中。如图5所示，当通信模块通过接收天线接收到接收信号时，芯片YA14D170/210/250可以作为ADC，将模拟信号转变为数字信号再传输至FPGA进行处理。当通信模块发送信号时，芯片YA14D170/210/250可以作为DAC，可以将接收到的来自FPGA的数字信号转变为模拟信号，再传输至射频前端，由射频前端放大后由发射天线发出。
一些实施例中，车辆还可以包括信号处理装置。信号处理装置可以包括软件定义的无线电(software defined radio，SDR)单元、软件无线电驱动(usrp hardware driver，UHD)单元、系统库、系统调用接口、内核(kernel)单元中的一个或多个。
其中，SDR单元的主要功能为处理系统的基带数据。SDR单元内部通过多层网络协议进行数据传输，例如物理(physical，PHY)层、媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据汇聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)、网络附属存储(network attached storage，NAS)层。SDR可以作为信号产生源或信号处理端。信号产生源可以产生初始信号(也即，上述FPGA接收到的初始信号)。信号处理端可以用于对接收到的信号进行解析处理。例如，可以对来自FPGA的信号进行解析处理。
需要说明的，SDR是一种无线电广播通信技术，它基于软件定义的无线通信协议而非通过硬连线实现。换言之，频带、空中接口协议和功能可通过软件下载和更新来升级，而不用完全更换硬件。
作为一种实现方式，信号处理装置与通信模块可以通过通用串行总线3.0(USB3.0)连接。
一种示例中，当车辆发射信号时，如图6所示，信号的发射过程可以包括：信号处理装置将系统中的基带数据通过USB3.0接口，发送至FPGA中的发送控制单元，发送控制单元将基带数据转发至FPGA中的数字上变频单元(DUC)，数字上变频单元对基带数据进行变频处理后，由DAC转换为模拟域的数据，以完成数模转换。进一步的，转换后的模拟信号经过低通滤波器(filter)进行滤波处理，得到中频模拟域信号。中频模拟域信号在与晶振产生的信号相乘，以使中频模拟域信号调制到预设的射频频点上，形成射频信号。射频信号再经过功率放大器由天线发射出去。
又一种示例中，当车辆接收信号时，如图7所示，信号的接收过程可以包括：车辆通过接收天线接收模拟信号，模拟信号经过低噪放后与晶振产生的信号相乘，以使信号的频率变为中频信号，再经过低通滤波器(filter)进行滤波处理，得到滤波后的中频信号。进一步的，中频信号由ADC转换为数字信号后，被送入FPGA中。此时，FPGA中的数字下变频单元(DDC)将数字信号从中频下变频到基带信号，再由FPGA中的接收控制单元将基带信号通过USB3.0接口发送至信号处理装置。
下面结合图2所示的网络架构，对本申请实施例提供的软件更新方法进行说明。
如图8所示，为本申请实施例提供的一种软件更新方法，该方法可以包括S201～S204。
S201、第一控制节点在获取到目标软件的更新后的版本信息后，广播第一指示信息。相应的，目标车辆接收来自第一控制节点的第一指示信息。
其中，第一控制节点可以为图2中的控制节点或控制节点中的器件(如芯片)。第一控制节点可以为服务器、车辆、移动终端等。目标车辆可以为与第一控制节点建立通信连接的车辆。例如，目标车辆可以为图2中的车辆1或车辆2。
需要说明的，当第一控制节点为车辆时，目标车辆与第一控制节点之间的距离小于或者等于预设距离，即目标车辆位于第一控制节点的广播范围内。
例如，在第一控制节点为第一车辆的情况下，目标车辆与第一车辆之间的距离小于或者等于预设距离。第一车辆可以为图2中的车辆3。该预设距离相当于第一车辆广播第一指示消息的广播距离，即当目标车辆与第一车辆之间的距离小于或者等于预设距离时，目标车辆可以成功接收到第一车辆广播的第一指示消息。
其中，第一指示信息用于指示车辆上报配置的目标软件的当前版本信息或者第一指示信息可以用于触发车辆上报配置的目标软件的当前版本信息。例如，第一指示信息可以包括目标软件的标识(如名称、软件序列号)。
需要说明的，目标软件可以为任意一款车辆软件，例如，目标软件可以为目标车辆上车载终端的应用程序(application，APP)，还可以为目标车辆配置的车机系统。技术人员对目标软件的更新，可以是对目标软件的升级，也可以是对目标软件存在的漏洞(BUG)进行的修复。
作为一种可能的实现方式，第一控制节点在确定目标软件更新之后，可以广播第一指示信息。
一种示例中，当第一控制节点为服务器时，服务器可以响应于技术人员更新服务器存储的目标软件的数据的操作，确定目标软件更新。服务器可以主动广播第一指示信息或者响应于技术人员的触发操作广播第一指示信息，用以通知配置有该目标软件的车辆进行升级。触发操作可以是指技术人员确定服务器存储的目标软件的数据已更新完成。例如，触发操作可以为技术人员断开设备与服务器之间的连接的操作。
例如，结合图1的实现方式，技术人员可以利用维护设备将更新的目标软件的数据存储到服务器中，当存储完成后，技术人员断开维护设备与服务器的连接。相应的，服务器响应于技术人员断开设备与服务器之间的连接的操作，广播第一指示信息。
结合图9的实现方式，技术人员还可以通过维护设备向服务器下发目标软件的升级信令，该信令中包含目标软件的更新数据以及更新后的版本信息，服务器在接收到目标软件的升级信令之后，将目标软件的更新数据以及更新后的版本信息通过OTA网关向多个车辆广播。
又一种示例中，当第一控制节点为车辆时，该车辆在完成对自身配置的目标软件的更新后，以广播的形式广播更新后的版本信息。如此，与该车辆之间的距离小于预设距离的车辆便可以接收到该更新后的版本信息。
例如，车辆在完成对自身配置的目标软件的更新后，可以通过无线局域网(WiFi)对附近车辆广播更新后的版本信息，还可以通过蓝牙对附近车辆广播更新后的版本信息。
又一种示例中，当第一控制节点为移动终端时(如智能手机、智能手表等)，用户在移动终端可以响应于用户的下载操作，从服务器中获取APP对应的安装包，并根据该安装包实现APP的安装。当目标车辆厂家对目标软件进行更新后，通过云服务器将目标软件的最新版本信息发送至移动终端的APP上。移动终端接收到云服务器发送的目标软件的最新版本信息后，通过移动终端上的APP提醒用户目标软件有新版本待更新。用户可以在该APP上点击确定更新，以触发目标软件的更新。相应的，移动终端在接收到用户点击的确定更新操作后，以广播的形式对附近车辆(包括用户自身的车辆)广播目标软件更新后的版本信息。
例如，移动终端可以通过自身热点对附件车辆广播更新后的版本信息，还可以通过蓝牙对附件车辆广播更新后的版本信息，还可以通过通信网络广播更新后的版本信息。
S202、目标车辆向第一控制节点发送配置的目标软件的当前版本信息。 相应的，第一控制节点接收目标车辆发送的当前版本信息。
其中，目标软件的当前版本信息用于反映目标车辆当前安装的目标软件的版本。比如，版本信息可以包括用于指示目标软件的版本号。例如，版本号可以包括一个或多个数字或字符。比如，版本号可以为：目标软件的协议名/产品名(A)、系列号(B)、主版本号(C)、副版本号(D)、子版本号(E)、日期版本号(F)、阶段版本号(G)等。
一种示例中，第一控制节点在接收到来自目标车辆上报的目标软件的版本信息之后，可以检测目标车辆上报的目标软件的版本信息与目标软件的更新后的版本信息是否相同。若两个版本信息不同，执行下述S203；若两个版本信息相同，则不执行下述S203，或者，循环执行上述S201。如此，可以保证扩大第一指示信息的广播范围，进而覆盖到更多的车辆，使得更多的车辆可以及时上报自身的版本信息。
需要说明的是，当第一控制节点为不同的设备时，检测软件的版本信息的方式也不同。
例如，当第一控制节点为服务器时，服务器将目标车辆发送的软件版本信息与厂家对目标软件更新后存储在服务器中的版本信息进行对比，判断两个版本信息是否相同。
又例如，当第一控制节点为第一车辆时，第一车辆将目标车辆发送的软件版本信息，与自身配置的目标软件的版本信息进行对比，判断两个版本信息是否相同。
又例如，当第一控制节点为移动终端时，移动终端将目标车辆发送的软件版本信息，与服务器下发的目标软件的更新后的版本信息进行对比，判断两个版本信息是否相同。
可选的，若确定目标车辆配置的目标软件的当前版本信息与目标软件的更新后的版本信息相同，第一控制节点还可以向目标车辆发送提示信息，以提示目标车辆的目标软件为最新版本。
S203、第一控制节点向目标车辆发送第二指示信息。相应的，目标车辆接收第一控制节点发送的第二指示信息。
其中，第二指示信息用于指示目标软件更新后的版本信息。例如，第二指示信息可以包括版本信息和/或者统一资源定位(uniform resource locator，URL)。
S204、目标车辆根据第二指示信息，更新目标软件。
其中，目标车辆根据第二指示信息，更新目标软件可以是指车辆根据第 二指示信息获取目标软件对应的更新数据，并根据获取到的更新数据更新所述目标软件。目标软件对应的更新数据可以为固件包。目标车辆在接收到第一控制节点发送的第二指示信息后，从第一控制节点中下载目标软件对应的最新版本的固件包。
一种示例中，第二指示信息包括目标软件更新后的版本信息。目标车辆在接收到第二指示信息后，向第一控制节点发送包括目标软件更新后的版本信息的下载请求信息，以请求下载对应版本信息的目标软件的更新数据。第一控制节点在接收到目标车辆的下载请求信息之后，将下载请求信息中版型信息对应的目标软件的更新数据发送至目标车辆。目标车辆接收到目标软件的更新数据后，根据更新数据更新目标软件。
可选的，下载请求信息中还可以包括目标车辆对目标软件的当前下载进度。其中，当前下载进度用于反映目标车辆已下载的目标软件的更新数据。第一控制节点在接收到目标车辆的下载请求信息之后，将目标车辆对目标软件的未下载部分的更新数据发送至目标车辆。
另一种示例中，第二指示信息包括URL。目标车辆在接收到第一控制节点发送的第二指示信息后，可以根据第二指示信息中的URL，从该URL对应的下载地址中获取目标软件对应的更新数据。进一步的，目标车辆根据更新数据更新目标软件。其中，URL对应的下载地址可以为第一控制节点，也可以为其他控制节点。
在目标车辆根据第二指示信息下载目标软件的安装数据的过程中，若目标车辆与第一控制节点断开连接，则目标车辆可以通过中断传输的方式从其他控制节点继续下载更新数据。具体的，可以下述实施例的描述。
目标车辆在获取到目标软件的更新数据之后，依据目标软件的更新数据对目标软件进行更新。例如，目标车辆可以将固件包解压缩，以替换掉目标软件当前版本的数据，从而完成对目标软件的更新。
上述实施例至少带来以下有益效果：目标车辆接收用于指示上报目标软件的版本信息的第一指示消息，以向当前建立通信连接的第一控制节点发送所述目标车辆配置的所述目标软件的当前版本信息。进一步，所述目标车辆接收所述第一控制节点发送的用于指示所述目标软件更新后的版本信息第二指示信息，以根据所述第二指示信息，更新所述目标软件。如此一来，可以实现对分布在各地的车辆进行软件更新，而无需用户驾驶车辆到指定地点由专业的技术人员进行软件更新，进而提高了车辆软件的更新效率。
一些实施例中，目标车辆在完成对目标软件的更新之后，还可以向第一 控制节点反馈第一响应消息，以指示目标车辆配置的目标软件更新成功。相应的，第一控制节点接收到目标车辆发送的第一响应消息之后，显示目标车辆更新成功。
为了方便理解，本申请实施例对第一控制节点为不同形式的情况下，第一控制节点与目标车辆进行目标软件更新时，具体更新流程作出介绍。
示例一，如图10所示，示出了第一控制节点为服务器时，目标车辆进行目标软件更新的流程。
其中，服务器中存储有厂家更新后的目标软件的版本信息以及固件包。
目标车辆通过公网向服务器上报自身配置的目标软件的当前版本信息。服务器接收到目标车辆上报的当前版本信息后，将厂家更新后的目标软件的版本信息与目标车辆上报的目标软件的当前版本信息进行对比，以判断两个版本信息是否相同。在版本信息不同的情况下，服务器向目标车辆发送包括URL的第二指示信息，以指示目标车辆对目标软件进行更新。目标车辆在接收到第二指示信息后，则根据第二指示信息中的URL，通过公网从服务器中下载目标软件更新后的固件包，同时，服务器显示目标车辆的下载进度。目标车辆下载完成固件包后，将该固件包进行解压缩，以覆盖掉目标软件当前版本的数据，完成对目标软件的更新，并向服务器反馈第一响应消息。相应的，服务器在接收到目标车辆反馈的第一响应消息后，显示目标车辆对目标软件更新成功。
可以理解的，上述示例中目标车辆通过公网从服务器中获取更新后的目标软件，无需通知用户，便可进行目标软件的自动升级，且数据传输速率可以得到保障。
示例二，如图11所示，示出了第一控制节点为第一车辆时，目标车辆进行目标软件更新的流程。
其中，第一车辆中存储有目标软件更新后的目版本信息以及固件包，且第一车辆与目标车辆之间的距离小于或者等于预设距离。
目标车辆向第一车辆上报自身配置的目标软件的当前版本信息。第一车辆接收到目标车辆上报的目标软件的当前版本信息后，将更新后的目标软件的版本信息与目标车辆上报的目标软件的当前版本信息进行对比，以判断两个版本信息是否相同。在版本信息不同的情况下，第一车辆向目标车辆发送包括URL的第二指示信息，以指示目标车辆对目标软件进行更新。目标车辆在接收到第二指示信息后，则根据第二指示信息中的URL从第一车辆中下载目标软件更新后的固件包，同时，第一车辆显示目标车辆的下载进度。目标 车辆下载完成固件包后，将该固件包进行解压缩，以覆盖掉目标软件当前版本的数据，完成对目标软件的更新，并向第一车辆反馈第一响应消息。相应的，第一车辆在接收到目标车辆反馈的第一响应消息后，显示目标车辆对目标软件更新成功。
可以理解的，上述示例中目标车辆通过从第一车辆中获取更新后的目标软件，有利于车辆软件升级的无盲点覆盖，类似具有传染性，当部分车辆升级以后，所有的同款车辆有相同的时空重叠时，便可以进行数据传输，当数据传输完成后进行车辆软件升级，不再依赖于公网，提升了覆盖范围。
示例三，如图12所示，示出了第一控制节点为移动终端时，目标车辆进行目标软件更新的流程。
其中，移动终端中存储有目标软件更新后的目版本信息以及固件包，且移动终端与目标车辆之间的距离小于或者等于预设距离。
目标车辆向移动终端上报自身配置的目标软件的当前版本信息。移动终端接收到目标车辆上报的当前版本信息后，将更新后的目标软件的版本信息与目标车辆上报的目标软件的当前版本信息进行对比，以判断两个版本信息是否相同。在版本信息不同的情况下，移动终端向目标车辆发送包括URL的第二指示信息，以指示目标车辆对目标软件进行更新。目标车辆接收到第二指示信息后，则根据第二指示信息中的URL从移动终端中下载目标软件更新后的固件包，同时，移动终端显示目标车辆的下载进度。目标车辆下载完成固件包后，将该固件包进行解压缩，以覆盖掉目标软件当前版本的数据，完成对目标软件的更新，并向移动终端反馈第一响应消息。相应的，移动终端在接收到目标车辆反馈的第一响应消息后，显示目标车辆对目标软件更新成功。
可以理解的，上述示例中目标车辆通过从移动终端中获取更新后的目标软件，当目标软件出现新版本后，通过移动终端上的APP及时提醒用户，以使用户可以及时的对目标软件进行升级。且用户可以根据自己的意愿选择是否升级，更加符合人性化需求，提升了用户体验。
一些实施例中，为了避免出现在下载过程中，目标车辆与第一控制节点断开连接，目标车辆无法继续从第一控制节点中下载目标软件的更新数据进而导致目标软件更新失败。目标车辆可以通过中断传输的方式从其他控制节点继续下载更新数据。如图13所示，本申请实施例提供的上述S204，具体包括下述S2041-S2043：
S2041、目标车辆建立与第二控制节点的通信连接。
作为一种可能的实现方式，在目标车辆从第一控制节点获取目标软件对应的更新数据的过程中，当目标车辆与第一控制节点之间的距离大于预设距离时，目标车辆与第一控制节点断开连接。进一步的，当目标车辆与第二控制节点之间的距离小于或者等于预设距离时，目标车辆建立与第二控制节点的通信连接。第二控制节点为配置有目标软件的更新后的安装数据的控制节点。第二控制节点可以为服务器、车辆、移动终端等。
需要说明的，第二控制节点与第一控制节点可以为同一个控制节点，也可以为不同的控制节点。当第二控制节点与第一控制节点为同一控制节点时，可以是指目标车辆与第一控制节点断开连接之后，目标车辆再次与第一控制节点建立连接。比如，当目标车辆停止驾驶(如车辆熄火后)，目标车辆无法继续正常通信，与第一控制节点断开连接；后续，目标车辆再次启动后，目标车辆可以正常工作，可以与第一控制节点再次建立连接。又比如，当目标车辆移动至第一控制节点的广播范围或覆盖范围后，断开与第一控制节点建立连接，后续的，目标车辆再次驶入第一控制节点的广播范围或覆盖范围，并再次建立与第一控制节点的连接。
可以理解的，由于车辆具有移动性，因此在目标车辆从第一控制节点获取目标软件对应的更新数据的过程中，目标车辆与第一控制节点之间的距离存在变化的可能，当目标车辆与第一控制节点之间的距离大于预设距离时，目标车辆与第一控制节点断开连接，此时目标车辆无法继续从第一控制节点中获取目标软件对应的更新数据。当目标车辆与第二控制节点之间的距离小于或者等于预设距离时，目标车辆则建立与第二控制节点的通信连接。
示例性的，第一控制节点为第一车辆，在目标车辆从第一车辆获取目标软件对应的更新数据的过程中，由于目标车辆或者第一车辆的移动，使得二者之间的距离大于预设距离，进而导致目标车辆与第一车辆断开连接。进一步的，目标车辆与第三车辆之间的距离小于或者等于预设距离，目标车辆建立与第三车辆的通信连接。也即，第一控制节点和第二控制节点为不同的控制节点。
又一例性的，第一控制节点为第一车辆，在目标车辆从第一车辆获取目标软件对应的更新数据的过程中，由于目标车辆或者第一车辆的移动，使得二者之间的距离大于预设距离，进而导致目标车辆与第一车辆断开连接。进一步的，目标车辆又驶入了第一车辆的覆盖范围内，即目标车辆与第一车辆之间的距离再次小于或者等于预设距离，此时目标车辆与第一车辆再次建立通信连接。也即，第一控制节点和第二控制节点为同一节点。
S2042、目标车辆向第二控制节点发送第一请求信息。
其中，第一请求信息用于请求获取目标数据，目标数据为目标软件对应的更新数据的全部或部分数据。
作为一种可能的实现方式，目标车辆建立与第二控制节点的通信连接之后，目标车辆向第二控制节点发送第一请求信息，以请求获取目标软件对应的更新数据的全部或部分数据。
可选的，若目标车辆与第一控制节点断开连接时，已经从第一控制节点中下载了部分目标软件对应的更新数据，则第一请求信息则用于请求获取目标车辆未下载部分的目标软件对应的更新数据。例如，第一请求信息可以包括目标车辆对目标软件的更新数据的当前下载进度。若目标车辆与第一控制节点断开连接时，未从第一控制节点中下载目标软件对应的更新数据，则第一请求信息则用于请求获取目标软件对应的全部更新数据。
相应的，第二控制节点接收目标车辆发送的第一请求信息，并根据第一请求信息向目标车辆发送目标数据。
S2043、目标车辆在获取到更新数据之后，根据更新数据，更新目标软件。
作为一种可能的实现方式，目标车辆从第二控制节点获取到目标数据后，目标车辆即得到了目标软件的全部更新数据。进一步的，目标车辆则依据目标软件对应的更新数据，对目标软件进行更新。
在一种设计中，如图14所示，目标车辆在完成对目标软件的更新之后，本申请实施例提供的软件更新方法，还可以包括下述S301-S304。
S301、目标车辆广播第一指示信息。
可以理解的，此时目标车辆已完成了对目标软件的更新，即目标车辆已具备了目标软件的更新后的版本信息，因此目标车辆可以作为第一控制节点继续辅助其他车辆进行目标软件的更新，进而扩大了目标软件的更新覆盖范围。
S302、目标车辆接收第二车辆发送的第二车辆配置的目标软件的当前版本信息。
其中，第二车辆与目标车辆建立通信连接。
可以理解的，第二车辆与目标车辆之间的距离小于或者等于预设距离。目标车辆在完成对目标软件的更新后，向周边车辆广播第一指示信息。相应的，周边车辆在接收到目标车辆的第一指示信息后，则向目标车辆发送各自配置的目标软件的当前版本信息。
S303、目标车辆根据第二车辆发送的当前版本信息，确定第二车辆配置 的目标软件的当前版本信息与目标软件的更新后的版本信息是否相同。
此步骤的具体实现方式可以参考上述S203，此处不再赘述。
S304、在第二车辆配置的目标软件的当前版本信息与目标软件的更新后的版本信息不同的情况下，目标车辆向第二车辆发送第三指示信息。
其中，第三指示信息用于指示目标软件更新后的版本信息。
可以理解的，由于目标车辆此时已完成了目标软件的更新，因此若第二车辆上报的目标软件的版本信息与目标车辆自身配置的目标软件的版本信息不同，目标车辆则认为第二车辆上的目标软件需要更新。因此，目标车辆将向第二车辆发送第三指示信息。相应的，第二车辆在接收到第三指示信息后，开启对目标软件的更新流程。
需要说明的，第三指示信息与第二指示信息的作用相同，均是为了向车辆指示目标软件更新后的版本信息，以使车辆开启对目标软件的更新流程。不同之处在于，第二车辆在接收到第三指示信息之后，将从目标车辆中获取目标软件对应的更新数据；目标车辆在接收到第二指示信息之后，将从第一控制节点中获取目标软件对应的更新数据。
在一种设计中，如图15所示，本申请实施例提供的软件更新方法，还可以包括下述S401-S403。
S401、第一控制节点建立与第三车辆的通信连接。
可以理解的，第一控制节点在与目标车辆进行目标软件的更新流程之外，还可以与第三车辆建立通信连接，以满足第三车辆对目标软件的更新需求。
S402、第一控制节点接收来自第三车辆的第一请求信息。
其中，第一请求信息用于请求获取目标数据，目标数据为目标软件对应的更新数据的全部或部分数据。
此步骤的具体实现方式可以参考上述S2052，此处不再赘述。
S403、第一控制节点根据第一请求信息，向第三车辆发送目标数据。
其中，目标数据为目标软件对应的更新数据的全部或部分数据。
此步骤的具体实现方式可以参考上述S2052，此处不再赘述。
需要指出的是，本申请各实施例之间可以相互借鉴或参考，例如，相同或相似的步骤，方法实施例、系统实施例和装置实施例之间，均可以相互参考，不予限制。
本申请实施例可以根据上述方法示例对软件更新装置进行功能模块或者功能单元的划分，例如，可以对应各个功能划分各个功能模块或者功能单元，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既 可以采用硬件的形式实现，也可以采用软件功能模块或者功能单元的形式实现。其中，本申请实施例中对模块或者单元的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
