具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供的一种通信方法，应用于车辆中；车辆中部署有域控制器，每个域控制器可以控制车辆的一个或多个功能。其中，域控制器与部署在服务器中的控制器，可以在车辆中的CAN(Controller Area Network，控制器局域网络)的基础上采用SOA通信协议进行通信，实现对车辆功能的控制。由于通过CAN获取车辆通信模块接收到的由服务器返回的控制响应消息后，可以通过CAN直接将对应的控制信号发送给对应的执行器，即可实现车辆功能的控制；从而当需要扩展车辆功能时，只需更改本地应用程序中与待扩展功能相关的参数即可，增强了车辆功能可扩展性。
其中，车辆中域控制器的功能，可以由部署在该域控制器本地的客户端程序(可以称为本地应用程序)实现；其中，不同的域控制器的功能，可以由不同的本地应用程序实现。控制器的功能，可以由部署在服务器中的服务端程序(可以称为服务)实现；其中，不同的控制器的功能，可以由服务器中不同的服务实现。
其中，对车辆功能的控制可以包括多种，如对车身功能的控制；如对动 力功能的控制，如对空调功能的控制，如对车灯功能的控制，如对后视镜功能的控制，如对座椅功能的控制等等，本发明实施例对此不作限制。
所述车辆通信模块可以是指用于车辆与其他设备通信的模块，如车载T-BOX(远程信息处理器)等，本发明实施例对此不作限制。
本发明实施例提供的通信方法，可以由车辆中具有CAN接口的控制器来执行，该控制器可以通过以太网与部署在域控制器中的本地应用程序通信，以及可以通过CAN总线由车辆通信模块与部署在服务器中的控制器通信。
其中，为了便于说明，可以将执行本发明实施例提供的通信方法的控制器，称为目标控制器。所述目标控制器可以是独立于域控制器的任一控制器，也可以是所有域控制器中的某一域控制器，本发明实施例对此不作限制。
以下分别以车辆发送消息和接收消息为例，对本发明实施例中的通信方法进行说明。
参照图1，示出了本发明的一种通信方法实施例的步骤流程图。
步骤102、获取所述车辆中本地应用程序生成的控制请求，所述本地应用程序为基于面向服务的架构SOA协议通信的本地应用程序。
步骤104、在所述车辆中的控制器局域网络CAN的基础上采用SOA协议，将所述控制请求发送至服务器。
本发明实施例中，部署在域控制器的本地应用程序，可以是基于SOA协议通信的本地应用程序。
当用户需要对车辆中的某一功能进行控制时，可以执行控制该功能所对应的控制操作；进而可以触发该本地应用程序生成控制请求。其中，用户可以通过在车辆中控屏中的触控操作来执行控制操作，也可以通过输入语音指令来执行控制操作；本发明实施例对此不作限制。
本地应用程序生成的控制请求后，可以将该控制请求发送至目标控制器；进而目标控制器可以获取到本地应用程序生成的控制请求。其中，本地应用程序可以通过以太网将控制请求发送至目标控制器。
然后目标控制器可以在CAN的基础上采用SOA协议，将所述控制请求发送至服务器；其中，可以按照基于CAN的SOA协议封装该控制请求，再 将封装后的控制请求由CAN通过车辆通信模块发送至服务器。
综上，本发明实施例中，可以获取所述车辆中本地应用程序生成的控制请求，所述本地应用程序为基于面向服务的架构SOA协议通信的本地应用程序；然后在所述车辆中的控制器局域网络CAN的基础上采用SOA协议，将所述控制请求发送至服务器；后续通过CAN获取由车辆通信模块接收的由服务器返回的控制响应消息后，可以通过CAN直接将控制信号发送给对应的执行器，即可实现车辆功能的控制；从而当需要扩展车辆功能时，只需更改本地应用程序中与待扩展功能相关的参数即可，增强了车辆功能的可扩展性。
参照图2，示出了本发明的一种通信方法可选实施例的步骤流程图。
步骤202、通过所述车辆中的控制器局域网络CAN，获取车辆通信模块接收的第一控制响应消息；所述第一控制响应消息是服务器基于所述车辆中本地应用程序生成的控制请求生成并返回至车辆通信模块的，所述本地应用程序为基于面向服务的架构SOA协议通信的本地应用程序。
步骤204、通过所述CAN将所述第一控制响应消息对应的控制信号发送至对应的执行器；以及基于所述执行器的执行结果，向所述本地应用程序返回第二控制响应消息。
本发明实施例中，服务器接收到车辆中目标控制器发送的控制请求后，可以对该控制请求进行解析，确定用于处理该该控制请求的目标服务；然后由目标服务对该控制请求进行处理，生成对应的控制响应消息；并将该控制响应消息返回给车辆的目标控制器。其中，为了便于后续区分，可以将目标服务对控制请求进行处理生成的控制响应消息，称为第一控制响应消息。
进而待服务器返回第一控制响应消息后，车辆的车辆通信模块可以接收到该第一控制响应消息，然后通过CAN将该第一控制响应消息发送至目标控制器。然后目标控制器可以先对第一控制响应消息进行解析，提取出控制信号，再通过CAN将该控制信号发送至对应的执行器，以指示该执行器执行该控制信号对应的操作。
待执行器执行该控制信号对应的操作后，可以将执行结果通过CAN返回给目标控制器；其中，所述执行结果包括：成功执行结果或失败执行结果。 所述成功执行结果可以是指执行器成功执行控制信号对应的执行结果，所述失败执行结果可以是指执行器未成功执行控制信息对应的执行结果。
然后目标控制器可以基于该执行结果，生成第二控制响应消息；然后向车辆中的本地应用程序，返回该第二控制响应消息。进而车辆中的本地应用程序可以根据该第二控制响应消息，输出用户针对车辆功能的控制结果，以便于用户获知对车辆功能的控制是否成功。其中，本地应用程序可以将控制结果发送至车辆的显示设备，由车辆的显示设备显示控制结果；也可以将控制结果发送至车辆内的语音助手由语音助手播报该控制结果等，本发明实施例对此不作限制。
综上，本发明实施例中，待服务器接收到车辆中本地应用程序的控制请求后，可以针对该控制请求生成第一控制响应消息并返回给车辆通信模块；进而可以通过所述车辆中的控制器局域网络CAN，获取车辆通信模块接收的第一控制响应消息，然后将所述第一控制响应消息对应的控制信号发送至对应的执行器；进而通过CAN直接将控制信号发送给对应的执行器，即可实现对车辆功能的控制；从而当需要扩展车辆功能时，只需更改本地应用程序中与待扩展功能相关的参数即可，增强了车辆功能可扩展性。然后还可以基于所述执行器的执行结果，向所述车辆中本地应用程序返回第二控制响应消息，以便于通过本地应用程序反馈给用户针对车辆功能的控制结果，提高用户体验。
以下结合车辆发送消息和接收消息两个过程，对本发明实施例的通信方法进行说明。
参照图3，示出了本发明的另一种通信方法可选实施例的步骤流程图。
步骤302、获取所述车辆中本地应用程序生成的控制请求，所述本地应用程序为基于面向服务的架构SOA协议通信的本地应用程序。
本发明实施例中，本地应用程序可以根据用户的控制操作生成控制请求，所述控制请求可以包括多种，如车窗开启请求、空调关闭请求、车门关闭请求、后视镜调整请求等等，本发明实施例对此不作限制。
然后本地应用程序可以将该控制请求发送给车辆的目标控制器，然后由目标控制器对所述控制请求进行处理，将在所述车辆中的控制器局域网络 CAN的基础上采用SOA协议，将所述控制请求发送至服务器；可以参照步骤304～步骤306：
步骤304、基于CAN通信协议，将所述控制请求封装成CAN请求报文。
步骤306、将所述请求CAN报文通过CAN发送至车辆通信模块，由所述车辆通信模块发送至服务器。
本发明实施例中，由于需要通过CAN接口来发送控制请求，因此可以先将控制请求封装成CAN报文，然后通过CAN将CAN报文发送至车辆通信模块，由所述车辆通信模块服务器。
其中，所述步骤304可以包括如下子步骤S3042～子步骤S3044：
子步骤S3042、基于CAN通信协议，将所述控制请求封装成连续的第一待处理数据。
子步骤S3044、对所述第一待处理数据进行分包处理，得到多个CAN请求报文。
本发明实施例中，可以先按照基于CAN的SOA协议传输数据的数据格式，将控制请求封装成连续的数据，可以得到第一待处理数据。由于CAN每次传输的数据量是有限的，为了能够通过CAN将控制请求发送至服务器，可以基于CAN通信协议，对连续的第一待处理数据进行分包处理，将连续的第一待处理数据划分为多个CAN报文。为了便于后续区分，可以将对第一待处理数据进行分包处理，得到的CAN报文，称为CAN请求报文。
一个示例中，所述基于CAN的SOA协议传输数据的数据格式可以如表1所示：
表1
字段 服务器ID 数据长度 终端ID 协议版本 信息类型 返回码 数据
  **** **** **** **** **** **** ****
当然，所述基于CAN的SOA协议传输数据的数据格式还可以包括其他形式，如还可以包括其他字段，或者这些字段的排序不同；且各字段对应的字节数可以按照需求设置，本发明实施例对此不作限制。
其中，第一待处理数据可以包括多个字节，如128个字节；若CAN每次传输的字节数为8个字节，则可以将该第一待处理数据划分为16个CAN 请求报文。
所述步骤306可以包括：调用CAN接口将所述CAN请求报文发送至所述车辆中的车辆通信模块，以由所述车辆通信模块将所述CAN请求报文发送至服务器。其中，可以确定用于发送CAN请求报文的CAN接口；然后调用CAN接口将所述CAN请求报文，通过CAN接口对应的物理硬件将CAN请求报文发至给车辆通信模块；由车辆通信模块将所述CAN请求报文发送至服务器。其中，所述车辆通信模块可以是移动网络通信模块，也可以是WIFI通信模块；当然还可以是其他通信模块，本发明实施例对此不作限制。
本发明的一个可选实施例中，目标控制器中可以部署有目标应用程序，可以由该目标应用程序实现在所述车辆中的控制器局域网络CAN的基础上采用SOA协议，将所述控制请求发送至服务器。其中，该目标应用程序可以构建基于CAN的SOA协议的网络结构，可参照图4，示出了本发明实施例的一种基于CAN的SOA协议网络结构示意图；所述基于CAN的SOA协议包括适配层、传输层、抽象层和驱动层，这多个逻辑层；可以由这多个逻辑层，实现在所述车辆中的控制器局域网络CAN的基础上采用SOA协议，将所述控制请求发送至服务器。可以如下：
本地应用程序根据用户的控制操作生成控制请求后，可以将该控制请求发送给适配层；由适配层获取所述车辆中本地应用程序生成的控制请求(即执行上述步骤302)；然后基于CAN通信协议，将所述控制请求封装成连续的第一待处理数据(即执行子步骤S3042)。再将第一待处理数据发送给传输层，由传输层对所述第一待处理数据进行分包处理，得到多个CAN请求报文(即执行子步骤S3044)。该传输层再将这多个CAN请求报文发送至抽象层，抽象层调用CAN接口；进而驱动层可以对该CAN接口对应的物理硬件进行驱动，从而实现将所述CAN报文发送至所述车辆中的车辆通信模块。
步骤308、通过所述车辆中的控制器局域网络CAN，获取车辆通信模块接收的第一控制响应消息；所述第一控制响应消息是服务器基于所述车辆中本地应用程序生成的控制请求生成并返回至车辆通信模块的，所述本地应用程序为基于面向服务的架构SOA协议通信的本地应用程序。
本发明实施例中，待服务器接收到目标控制器发送的控制请求对应的多个CAN请求报文后，可以将这多个CAN请求报文进行组包，得到连续的数据。其中，可以确定目标控制器将连续的数据划分为多个CAN请求报文的划分方式，以及发送这多个CAN请求报文的发送方式；然后基于该划分方式和发送方式，对这多个CAN报文进行组包。
然后服务器可以按照基于CAN的SOA协议对连续的数据进行解析，确定该控制请求所请求控制的对象、针对所述对象所请求控制的功能，以及针对所述功能的控制方式。其中，所述控制请求所请求控制的对象可以包括多种，如车窗、车门、座椅、油门、刹车等等，本发明实施例对此不作限制。所述针对所述对象所请求控制的功能可以包括多种，例如当对象为座椅时，针对座椅所请求控制的功能可以包括前后移动功能、上下移动功能、靠背角度调整功能等等；当对象为车窗时，针对车窗所请求控制的功能可以包括开合功能；等等。以及对针对所述功能的控制方式可以包括多种，例如，当功能为针对座椅的前后移动功能时，对应的控制方式可以包括：向前移动、先后移动；当功能为针对车窗的开合功能时，对应的控制方式可以包括：打开车窗、关闭车窗；等等。
然后根据该控制请求所请求控制的对象，和针对所述对象所请求控制的功能，确定实现所请求控制的功能对应的执行器和该执行器对应的标识信息。再按照基于CAN的SOA协议根据该标识信息和控制方式，生成用于指示该执行器执行对应操作的控制信号；并基于该控制信号生成第一控制响应消息。其中，第一控制响应信息也是连续的数据；进而服务器可以将第一控制响应信息进行划分，得到对应的多个第一CAN响应报文；并将第一控制响应信息对应的第一CAN响应报文发送给目标控制器。
进而待服务器返回第一控制响应消息后，车辆的车辆通信模块可以接收到该第一控制响应消息，然后通过CAN将该第一控制响应消息发送至目标控制器。目标控制器接收到的第一控制响应信息可以包括多个第一CAN响应报文；然后由目标控制器通过CAN将所述第一控制响应消息对应的控制信号发送至对应的执行器；可以参照步骤310～步骤314：
步骤310、将所述多个第一CAN响应报文进行组包，得到连续的第二 待处理数据。
步骤312、从所述第二待处理数据中提取出控制信号。
步骤314、将所述控制信号发送至所述标识信息对应的执行器，由所述执行器执行所述控制信号对应的操作。
本发明实施例中，目标控制器可以获取服务器将连续的数据划分为多个第一CAN响应报文的划分方式，以及发送这多个第一CAN响应报文的发送方式；然后基于该划分方式和发送方式，对这多个第一CAN响应报文进行组包，得到对应连续的数据(后续称为第二待处理数据)。所述第二待处理数据中包含了用于指示执行器执行操作的控制信号；因此可以从所述第二待处理数据中提取控制信号。再将该控制信号发送至该标识信息对应的执行器；执行器接收到该控制信号后，可以执行该控制信息对应的操作，来实现对车辆功能的控制；如左车窗执行器接收到开窗信号时，可以打开左车窗；空调执行器接收到关闭信号时，可以关闭空调；等等。
在上述示例所述基于CAN的SOA协议可以包括：适配层、传输层、抽象层和驱动层这多个逻辑层的基础上，可以由驱动层驱动对应的物理硬件接收服务器发送的第一控制响应消息(即执行步骤308)；然后由抽象层通过CAN接口获取物理硬件接收到的由服务器发送的第一控制响应消息，并将该第一控制响应消息发送至传输层。传输层可以执行上述步骤310～步骤314，实现将所述控制信号发送至对应的执行器。
本发明实施例中，在执行器执行控制信号对应的操作后，可以将执行结果返回给目标控制器，由目标控制器基于该执行结果，向所述车辆中本地应用程序返回第二控制响应消息，可以参照步骤316～步骤318：
步骤316、采用所述执行器的执行结果，生成连续的第三待处理数据。
步骤318、对所述第三待处理数据进行解析，得到第二控制响应消息并向所述本地应用程序返回第二控制响应消息。
本发明实施例中，可以按照基于CAN的SOA协议的数据格式，采用服务器返回的第一控制响应消息对应的第二待处理数据和执行器的执行结果，生成连续的数据(后续可称为第三待处理数据)。由于本地应用程序是采用基于以太网的SOA协议进行通讯的，进而可以按照基于以太网的SOA协议， 对该第三待处理数据进行解析，得到第二控制响应消息；然后将该第二控制响应消息发送给车辆的本地应用程序。
其中，所述步骤316～步骤318，可以依据由基于CAN的SOA协议中的适配层实现。
综上，本发明实施例中，在发送控制请求的过程中，可以基于CAN通信协议，将所述控制请求封装成CAN请求报文；然后将所述请求CAN报文通过CAN发送至车辆通信模块，由所述车辆通信模块发送至服务器，进而能够快速的将控制请求发送中服务器。
其次，本发明实施例中，在接收到服务器返回的第一控制响应消息后，可以将所述第一控制响应消息中的多个第一CAN响应报文进行组包，得到连续的第二待处理数据；然后从所述第二待处理数据中提取出控制信号，将所述控制信号发送至所述标识信息对应的执行器，由所述执行器执行所述控制信号对应的操作；进而无需信号的转换，直接将从第一响应消息中的提取的信号通过CAN发送至对应的执行器，从而提高对车辆功能控制的效率。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本发明实施例所必须的。

消息发送模块704，用于通过所述CAN将所述第一控制响应消息对应的控制信号发送至对应的执行器；以及基于所述执行器的执行结果，向所述本地应用程序返回第二控制响应消息。
参照图8，示出了本发明一种通信装置可选实施例的结构框图，具体可以包括如下模块：
本发明的一个可选实施例中，所述第一控制响应信息包括多个第一CAN响应报文，所述消息发送模块704可以包括：
数据组包子模块7042，用于将所述多个第一CAN响应报文进行组包，得到连续的第二待处理数据；
信号提取子模块7044，用于从所述第二待处理数据中提取出控制信号；

综上，本发明实施例中，待服务器接收到车辆中本地应用程序的控制请求后，可以针对该控制请求生成第一控制响应消息并返回给车辆通信模块；进而可以通过所述车辆中的控制器局域网络CAN，获取车辆通信模块接收的第一控制响应消息，然后将所述第一控制响应消息对应的控制信号发送至对应的执行器；进而通过CAN直接将控制信号发送给对应的执行器，即可实现对车辆功能的控制；从而当需要扩展车辆功能时，只需更改本地应用程序中与待扩展功能相关的参数即可，增强了车辆功能可扩展性。然后还可以基于所述执行器的执行结果，向所述车辆中本地应用程序返回第二控制响应消息，以便于通过本地应用程序反馈给用户针对车辆功能的控制结果，提高用户体验。对于装置实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
本发明实施例还提供了一种车辆，包括有存储器，以及一个或者一个以上的程序，其中一个或者一个以上程序存储于存储器中，且经配置以由一个或者一个以上处理器执行所述一个或者一个以上程序包含用于执行如本发明实施例任一所述的通信方法。
