具体实施方式
下文中将参考附图并结合实施例来说明本公开。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，说明书中的术语“第一”、“第二”等是用于区别类似的对象，而不是用于描述特定的顺序或先后次序。
实施例1
图1是本实施例的车载应用系统升级方法的流程图，如图1所示，该方法包括如下步骤：
步骤102，确定车辆群组内所包括的车辆的车载应用系统的最高版本，其中，车辆群组内所包括的车辆之间通过无线保真Wifi直连技术进行通信；
步骤104，利用从所述车辆群组内确定的目标车辆的车载应用系统和Wifi直连技术，将车辆群组内所包括的车辆的车载应用系统均升级到上述最高版本。
本实施例提供的车载应用系统升级方法中，车辆之间通过Wifi直连技术进行通信，实现了将车辆群组内的车辆的车载应用系统均升级到最高版本，解决了相关技术中存在车载应用系统的升级过程繁琐的问题，简化了升级流程、提高了系统升级便捷性。
可选地，可以采用多种方式实现将车辆群组内的车辆的车载应用系统均升级到最高版本。例如，可以采用具有最高版本的车辆(例如，车辆A)对其余车辆中的一个(例如，车辆B)进行升级，然后两个车辆(车辆A和车辆B)再分别对其余车辆进行升级，依次类推，直到所有的车辆均升级到最高版本。又例如，在从车辆群组内确定的一个目标车辆对应的系统版本不是最高版本的情况下，可以将目标车辆的车载应用系统版本升级到最高版本；更新目标车辆对应的可升级列表，其中，目标车辆对应的可升级列表包括待升级车辆的信息，待升级车辆为车辆群组中车载应用系统的系统版本低于目标车辆的系统版本的车辆；将更新后的目标车辆对应的可升级列表中的待升级车辆的车载应用系统版本升级到最高版本。再例如，在目标车辆的系统版本是最高版本的情况下，可 以确定目标车辆对应的可升级列表(与前述可升级列表类似)，将目标车辆对应的可升级列表中的待升级车辆的车载应用系统版本升级到最高版本。
车辆群组内除了目标车辆以外的其他车辆(例如某一指定车辆)也可以具有对应的可升级列表。指定车辆对应的可升级列表中包含待升级车辆的信息，而待升级车辆为车辆群组中车载应用系统的系统版本低于指定车辆的系统版本的车辆。目标车辆可以为该群组中的组拥有者(Group Owner)，或者称为组所有者、组主持人，可以通过协商确定。
可选地，在将目标车辆的系统版本升级到最高版本之前，还可以首先将目标车辆对应的可升级列表中的待升级车辆升级到目标车辆的系统版本。后续再将待升级车辆的系统版本升级到最高版本。在目标车辆对应的可升级列表更新为目标车辆的车载应用系统版本为最高版本时所对应的可升级列表后，再将更新后的可升级列表中的待升级车辆的车载应用系统升级到最高版本。通过上述分段升级的方式，可以避免由于版本间隔过大导致升级时间过久而使升级中断的问题。
可选地，在待升级车辆为至少两个的情况下，可以根据可升级列表中待升级车辆对应的系统版本的版本信息，按照预设策略，将至少两个待升级车辆对应的系统版本升级到最高版本，其中，上述预设策略可以为优先升级与目标车辆的系统版本的版本间隔最小的待升级车辆的车载应用系统(可以保证系统升级的成功率)，也可以是优先升级与目标车辆的系统版本的版本间隔最大的待升级车辆的车载应用系统(可以保证群组内每个车辆的车载应用系统的系统版本不会过低)，还可以是优先升级与目标车辆连接时间较早的待升级车辆的车载应用系统。
在车载系统中，对于更新频率需求比较高的车载应用，例如导航系统，较好的方式是能够方便地升级，即便是车辆不能够到售后点还能够进行升级。
本实施例提供的车载应用系统升级方法，使得车载应用系统能够更方便的升级。通过无线保真直连Wifi Direct技术，多个车辆之间可以互相发现并组网，同时可以判断组网中的车辆是否已经具备了较新的车载应用系统，如果组网中有车辆具有相对较新的车载应用系统，则系统版本较低的车辆进行系统更 新请求，并通过Wifi Direct技术从其他车辆中下载目标系统到本车辆中，并更新。使得用户不需要进入售后点进行系统升级，或者用户自己手动去进行升级，通过与其他车辆进行Wifi Direct组网，就可以自动完成车载应用系统的升级。本优选实施例中所提供的车载应用系统升级方法可以应用于基于Wifi Direct(直连)技术的车载应用更新系统中，该系统主要包括：支持Wifi Direct的车载无线路由装置、支持Wifi的车载装置或者支持Wifi的外部导航仪装置。下面对每个装置进行说明。
支持Wifi Direct的车载无线路由装置可以包括：Wifi Direct自动发现组网子系统，系统对比发现子系统，系统更新策略子系统，最新系统存储子系统，无线路由上网子系统和车载信息交换子系统。
其中，Wifi Direct自动发现组网子系统，负责在本车辆周围出现同样类型的车辆时候，车载无线路由可以根据Wifi Direct协议的发现组网机制，完成Wifi Direct的自动组网。由于Wifi Direct的覆盖范围是比较大的(例如可以覆盖两个足球场)，在这个范围出现的Wifi Direct终端可能比较多，因此要根据发现的Wifi Direct终端的信号强度，来进行判断，符合预设的信号强度，才可以进行组网。在组网的过程中，由于版本升级的不连续性，只有和Group Owner可以进行互相升级的车辆才可以加入进组，同一组网内可以设置5辆车辆为上限。
系统对比发现子系统，负责使组网中的Wifi Direct从设备(除Group Owner以外的设备或者称为车辆)，将自己的车载应用系统的版本号发送到组网中的Wifi Direct主设备(Group Owner)，主设备对比自己和从设备发送的版本号，同时记录每个从设备的信息。
系统更新策略子系统，负责进行升级策略的更新。由于同一组网(与前述车辆群组类似)中的多个车辆的系统版本并不相同，而且同时如果每个子系统同时升级到最新的系统会耗费更多的信息，因此需要进行升级策略的更新，例如，可以按车载应用系统的版本进行从低级升向高级的方式升级(也可以按照系统版本间隔由小到大的方式升级)。升级时，其他车辆的升级请求忽略。在完成一次升级后，系统更新策略子系统再次更新策略，同时更新每个车辆自带的 可升级列表，再继续进行升级。
当组网内有两个车辆且有两种系统版本时，系统版本较低的系统升级到版本号较高的系统。当组网内有三个车辆且具有三个不同版本号的系统时候，首先确定Group Owner，优先升级最低版本到Group Owner的系统版本，之后再升级剩下的一个低版本的系统到Group Owner的系统版本，最终三辆车辆的车载应用系统的版本一同升级到最高版本。当系统更新中断时，需要保存最近的两个不同系统版本，若再次组网后发现不同的版本，则会删除一个，可以优先删除完成百分比少的那个。
无线路由上网子系统，负责在Wifi Direct模块未能完成系统更新升级，而且处在有上网条件的时候，配置为通过无线路由上网子系统进行版本更新，通过无线上线上网下载系统进行更新。默认的设置可以为Wifi Direct模块优先。
最新系统存储子系统在获取最新版本的系统后，将最新版本的系统存储在车载无线路由系统中。
车载信息交换子系统，负责与车载装置Wifi成功连接后，车载无线路由系统将会读取车载导航系统的版本号。当最新系统存储子系统获取最新版本的系统后，车载信息交换子系统将通过Wifi在线升级的方式升级车载装置中的导航系统。
支持Wifi的车载装置包括：车载装置Wifi模块和导航系统。
本实施例中提供的车载应用系统升级方法描述了一种基于Wifi Direct技术，以三个车辆(A车、B车和C车)的车载应用系统自动升级的实现方式为例进行说明。在使用前，A车、B车和C车的车载路由设备已经开启，车载设备的Wifi已经打开，并与车载路由设备进行了Wifi连接，三台车辆的车载路由设备默认设置都是优先从Wifi Direct发现组网中升级。该车载应用系统升级方法包括如下步骤：
第一步：车载设备的Wifi打开，并且与车载路由设备连接，通过Wifi车载路由设备获取当前车载设备中的车载应用系统的版本信息。在本实施例中，A车的应用系统版本为B04版本，B车的应用系统版本为B05版本，C车的应用系 统版本为B01版本；
第二步：车载路由设备的Wifi Direct功能启动，自动发现组网子系统启动，在Wifi Direct技术基础上，A、B、C三车自动互相发现并进行Wifi Direct组网，在组网的过程中，A车的可升级列表包括C车B01版本，B车的可升级列表包括A车的B04版本与C车的B01版本。A车的可升级列表表明允许C车的系统从B01升到B04，B车的可升级列表表明允许A车的系统从B04涉及到B05或者允许C车的系统从B01升级到B05；
第三步：A、B、C三车的车载路由设备交换彼此的车载应用系统版本，根据车载路由设备中的系统更新策略子系统生成更新策略，由于Group Owner是协商确定的，A、B、C均有可能成为Group Owner。
当A车为Group Owner时，A车自己本身带有一个可升级列表，同时也知晓B车与C车的可升级列表，优先升级C车到A车，升级成功，将A车的可升级列表更新到C车；升级A车到B车，升级成功，将B车的可升级列表更新到A车；再升级C车到A车，升级成功，将A车的可升级列表更新到C车。最终三车均达到最高版本(B05)；
当B车为Group Owner时候，则C车与B车之间进行升级，C车的系统升级到B05，升级成功，将B车的可升级列表更新到C车；同时B车与A车之间进行升级，A车升级到B05，升级成功，将B车的可升级列表更新到A车；最终三车达到最高版本(B05)(在优先策略为版本间隔由小到大的情况下，先将A车的系统升级到B05，然后将C车的系统升级到B05)；
当C车为Group Owner时候，C车与B车之间进行升级，C车的系统升到B05，同时将B车的可升级列表更新到C车上，之后C车与A车之间再升级，A车的系统升到B05，同时更将C车的新A车的可升级列表更新到A车上。最终三车的系统达到最高版本(B05)。
第四步：每个车辆在版本升级完成后，最新系统存储子系统将最新的系统应用版本暂时保存在车载无线路由中，最新系统存储子系统本身还包括车辆的升级前的系统版本。
第五步：车载无线路由通过Wifi与车载装置连接的，通过车载装置信息交 换子系统，将下载成功的最新版本的车载应用系统传输到车载装置中的特别保留区域；
第六步：车载装置的特别保留区域已经有最新的车载应用系统版本的情况下，通过重新启动车载装置，加载最新的车载应用系统，完成整个系统的版本升级过程。
图2是本实施例的又一种车载应用系统升级方法的流程示意图，如图2所示，该方法包括如下步骤：
步骤202，车载无线路由系统与车载装置通过Wifi进行连接。
步骤204，车载信息交换子系统通过Wifi从车载装置中获取需要升级的应用系统的版本信息(例如导航系统的版本号)。
步骤206，车载无线路由系统采用Wifi Direct技术，向四周发送Wifi Direct广播信息，以便被其他车载无线路由发现，并组网。
步骤208，车载无线路由在通过Wifi Direct技术协商后，并且根据收到的Wifi信号强度粗略判断相对位置的远近，自动组网，将每个车辆组网，最多不超过5个，在服务器发现Service Discovery阶段，参与组网的车辆将会对比各自的可升级列表，只有可以互相升级的车辆才允许加入到组网中。
步骤210，自动组网成功后，群组的Group Owner在满足条件时候(例如群组满足为5个，或者在1分钟内没有新成员加入)，Group Owner负责启动升级过程。
步骤212，系统更新策略子系统进行系统升级的策略指派，Group Owner从系统对比发现子系统中获取其他组成员(Group Client)(即车辆)的信息，并且判断当前Group Client的支持能力(例如需要升级的空间是否满足)。如果带宽足够，同时启动其他可升级的车辆进行升级。
步骤214，Group Owner和Group Client在获取升级指令后，进行Wifi Direct传输，直至成功进行版本升级；
步骤216，在目标Group client车载无线路由系统中，最新系统存储子系统存储了新的版本；
步骤218，在目标Group Client车载无线路由系统中，车载信息交换子系 统下发升级版本命令，车载无线路由系统将最新的应用系统版本，传输到车载装置的系统升级特别保留区域，等待用户的升级动作；
步骤220，当群组中的Group Owner退出群组时候，要发送信息给群组中其他车载无线路由系统，群组需要重新进行组网过程，并确定新的Group Owner，确定好后，继续进行升级的过程。
下面通过一个实例说明两个车辆如何通过Wifi Direct进行连接和自动组网。
图3是本实施例中的两车辆通过WiFi Direct连接交互过程的示意图，如图3所示，具有Wifi Direct功能的A、B两车辆默认的状态处于向周围搜索，看是否具有可以连接的Wifi Direct终端(或设备)，周期地向其他车辆发送搜索请求Probe request消息，发送三次请求后，进入监听listen状态。B车在侦听Listen状态时，收到A车发出的Probe request消息，并返回搜索答复Probe response消息，表明自己处于可以连接的状态，等待A车的回复。A车接下来将会发送服务发现查询Service Discovery Query消息，在该实例中，是自动升级车载系统的一个服务，同时A车将自己的可升级列表信息，在Service Discovery Query消息中一起发送。B车在收到该消息后，解析出A车的可升级列表，并对解析出的可升级列表进行分析(如图4所示)。如果符合互相升级条件，则回复服务发现答复Service Discovery Response成功的消息。如果不符合互相升级条件，则回复Service Discovery Response失败消息，整个过程会终止。接下来A车发出组拥有者协商请求GO(Group Owner)Negotiation request消息，进行组网请求。B车收到该组拥有者协商请求消息后，对A车的Wifi信号强度进行分析，满足Wifi信号强度条件后，回复组拥有者协商答复(成功)GO Negotiation response(success)消息。A车再回复组拥有者协商确认GO Negotiation confirmation消息，组网成功，最终确定组拥有者GO与组成员Client角色。组网成功以后，GO会发送信标Beacon消息，Client则进行4次握手消息，最终建立数据传输连接，进行数据业务传输。
升级过程的触发由GO来决定，在1分钟内GO没有再收到加入组的请求，则认为当前群组稳定，启动升级过程。如果持续收到加入组的请求，并且小组 成员满足5个的时候，不再等待加入小组请求，启动升级过程。
升级策略可以是，按照先升级比GO小的版本，再升级比自己大的版本策略，如果GO是最小的版本则先将自己升级到最高版本。
下面车载应用系统升级系统进行说明，图5是基于Wifi Direct的车载应用系统升级系统的结构示意图，如图5所示，该升级系统包括：车载无线路由装置52和车载装置54，其中，车载无线路由装置52包括：Wifi Direct模块522、无线路由上网模块524、Wifi模块526、自动发现组网子系统528、系统对比发现子系统5210、系统更新策略子系统5212、车载信息交换子系统5214和最新系统存储子系统5216；车载装置54包括车载装置Wifi模块542、导航系统544、广播系统546、视频系统548和系统升级特别保留区域5410。
在加入组的过程中，如果不对加入组的车辆进行判别，不对可升级列表进行判别，而是在组网成功后，由GO发起升级时来进行判断，但这样方式升级效率会比较低，有可能出现组网成功，但是最终却无法升级的情况。
本实施例提供的车载应用系统升级方法中，由于是基于Wifi Direct技术，不需要人工去更新升级车载应用的系统；可以使得通过Group Owner的更新，最终实现了组内的车辆互相同步升级，在效率上大大提高了更新升级效率。
通过以上的实施方式的描述，本领域的技术人员可以了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，本公开的技术方案可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开上述实施例所述的方法。
