相关申请的交叉引用
本公开要求比亚迪股份有限公司于2018年04月20日提交的、发明名称为“基于车载以太网的信息交互系统以及车辆”的、中国专利申请号“201810360622.3”的优先权。
技术领域
本公开涉及汽车技术领域，尤其涉及一种基于车载以太网的信息交互系统以及车辆。
背景技术
随着车辆的日益增多，为了方便驾驶安全查看四周环境，保证驾驶安全，车辆上一般设置有全景影像设备，全景影像设备通过摄像头采集周围环境的视频，并拼接成全景视频，并在车辆中控台的屏幕上显示该全景视频。
相关技术中，全景影像设备与车辆多媒体系统通过低电压差分信号(Low-Voltage Differential Signaling，LVDS)连接传输拼接的全景视频。具体而言，全景影像设备中的全景主控制器直接将视频传输到LVDS的转换IC集成电路(Integrated Circuit)，进行并串转换后，再由LVDS传输到车辆多媒体系统中，多媒体系统完成串并转换，并在车辆中控台的屏幕上显示该全景视频。
然而，在实现本公开的过程中发明人发现相关技术至少存在如下技术问题：在整个传输过程中，LVDS只能在物理层传输有固定格式的视频信息，灵活性非常低，不会对视频进行处理，也不能传输图片和文件信息。除此之外，LVDS的信号传输距离也有限，有很大的局限性，而且转换IC和线材的硬件成本相对较高。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的基于车载以太网的信息交互系统以及车辆。
图1是根据本公开一个实施例的基于车载以太网的信息交互系统的结构示意图。
如图1所示，该基于车载以太网的信息交互系统包括中控多媒体设备110、车载以太网网关120和全景影像设备130。其中：
车载以太网网关120，分别与中控多媒体设备110和全景影像设备130连接，用于在中控多媒体设备110和全景影像设备130之间进行数据传输。
其中，中控多媒体设备110是指具有车辆中控系统和多媒体功能的设备。
需要理解的是，中控多媒体设备110具有显示屏，用户可通过触摸该显示屏控制车辆、播放多媒体等。例如，用户可通过触摸显示屏的相关控件播放音乐MV。
全景影像设备130，设置有第一以太网接口131，用于通过第一以太网接口131向车载以太网网关120发送全景视频数据。
作为一种示例性的实施方式，全景影像设备130可以包括但不限于全景主控制器(图中未示出)和多个设置在车辆上的摄像头(图中未示出)，其中，全景主控制器用于将摄像头采集的视频进行拼接，形成全景视频。
中控多媒体设备110，设置有第二以太网接口111，用于通过第二以太网接口111从车载以太网网关120获取全景视频数据，并展示全景视频数据。
本示例的基于车载以太网的信息交互系统，通过中控多媒体设备与全景影像设备设置有统一标准的以太网接口，从而使得中控多媒体设备与全景影像设备之间通过车载以太网网关实现了以太网通信，由于以太网具有成熟的系统构架，物理层，数据链路层，传输层，网络层，应用层，完整的系统架构不仅保证了信息可靠的传输，而且使得传输更加灵活，支持各种形式(例如文本、图片、视频等)的数据传输，由此，使得中控多媒体设备与全景影像设备之间可以采用多种形式进行数据交互，丰富了控多媒体设备与全景影像设备之间的交互方式。
另外，需要说明的是，相对于LVDS线材来说，以太网线束的价格要低很多，例如，一米LVDS线材的价格大约为38人民币，一米太网线束的价格大约为2人民币，因此，本实施例中通过以太网实现中控多媒体设备与全景影像设备之间的通信，可以大大降低基于车载以太网的信息交互系统的成本。
作为一种示例性的实施方式，中控多媒体设备110中可以包括视频格式转换单元(图中未示出)，其中，该视频格式转换单元在监控到从车载以太网网关120获取的全景视频数据的格式与中控多媒体设备110所支持的视频格式不一致时，对所获取的全景视频数据进行格式转换，以使得中控多媒体设备110显示转换格式后的全景视频数据，由此，使得中控多媒体设备可以与各种视频格式的全景影像设备之间进行通信，即，中控多媒体设备与全景影像设备之间视频数据传输的格式不再固定，丰富了中控多媒体设备与全景影像设备之间视频数据的格式。
综上，本公开实施例的基于车载以太网的信息交互系统，通过中控多媒体设备与全景影像设备设置有统一标准的以太网接口，从而使得中控多媒体设备与全景影像设备之间通过车载以太网网关实现了以太网通信，由于以太网可以支持多种形式的数据交互，并且以太网线束成本较低，从而，一方面，使得中控多媒体设备与全景影像设备之间可以采用多种形式进行数据交互，丰富了控多媒体设备与全景影像设备之间的交互方式。另一方面降 低了中控多媒体设备与全景影像设备之间通信的成本。
相关技术中，一般多媒体设备与全景影像设备通过LVDS连接传输全景的拼接视频，行车记录仪通过同轴电缆线将摄像头数据传输到内后视镜显示，由此，可以看出，多媒体设备与全景影像设备，以及行车记录仪与内后视镜之间采用不同的通信方式进行通信。也就是说，多媒体设备、全景影像设备和行车记录仪不再同一个系统中之间交互，两个系统各自独立，不相互交互。为了合理利用多媒体资源，实现多媒体资源的复用，作为一种示例性的实施方式，中控多媒体设备110不仅可以显示全景视频，还可以显示行车记录设备的行车视频，下面结合图2对基于车载以太网的信息交互系统进行描述，图2是根据本公开另一个实施例的基于车载以太网的信息交互系统的结构示意图。

其中，中控多媒体设备110，还用于通过第二以太网接口111从车载以太网网关120获取行车视频数据，并展示行车视频数据。
由此，可以看出，相对于上述中控多媒体设备与全景影像设备采用一种方式通信，而行车记录设备采用另一种方式通信来说，在本实施例中，行车记录设备、中控多媒体设备与全景影像设备设置有统一标准的以太网接口，从而统一了三个设备之间的通信方式，简化了中控多媒体设备与全景影像设备和行车记录设备之间的信息交互方式，实现了中控多媒体设备的多媒体资源复用。

当然，诊断设备190还可以对其他接入车载以太网网关120的其他设备进行故障检测，以方便用户通过诊断设备190对与车载以太网网关120的设备进行故障检测。
其中，需要说明的是，上述图8所示的系统实施例中的诊断设备190的结构也可以包含在前述图2-图6所示的系统实施例中，该实施例对此不作限定。
在本实施例中，为了方便管理与车载以太网网关连接的设备，可通过接插件统一不同 设备交互的接口电路，在图1所示的系统实施例的基础上，如图9所示，该系统还可以包括：
接插件210，接插件210的一端与车载以太网网关120连接，接插件210的另一端与车载以太网网关120连接的设备连接。
其中，与车载以太网网关120连接的设备可以包括但不限于中控多媒体设备110和全景影像设备130。
其中，需要理解的是，随着应用场景的不同，与车载以太网网关120连接的设备不同。
与车载以太网网关120连接的设备均通过插接件210与以太网交换芯片连接。
在本实施例中，为了使得车载以太网网关可接入较多的设备，以太网交换芯片的数量为多个，多个以太网交换芯片可采用级联方式连接。
其中，多个以太网交换芯片可以包括第一以太网芯片和第二以太网芯片。
其中，第一以太网交换芯片上设置有多个车载以太网端口、至少一个介质无关(Media Independent Interface，MII)端口和至少一个串行吉比特介质独立端口SGMII(Serial Gigabit Media Independent Interface)端口。
其中，车载以太网端口100base-T1可以支持100兆(M)以太网。
其中，通用以太网端口100Base-Tx可以支持100M以太网。
其中，需要说明的是，SGMII端口可以支持10兆(M)、100M和1000M以太网。
其中，第二以太网交换芯片上设置多个车载以太网端口、至少一个通用以太网端口、至少一个介质无关端口和至少一个SGMII端口。
其中，第一以太网交换芯片的介质无关端口与第二以太网交换芯片的介质无关端口连接。
作为一种示例，第一以太网交换芯片和第二以太网交换芯片均可以采用以Marvel公司的Q5050，此芯片集成度高，体积小，Q5050芯片一共集成了至少4个车载以太网端口100Base-T1的PHY物理层以及一个传统以太网端口100Base-Tx的PHY，其他端口可以灵活的配置，可以配置为支持1000M以太网，也同时支持10M和100M的SGMII或GMII端口，也可以配置成为只支持100M和10M的MII端口，用于连接物理层PHY和介质访问控制(Media Access Control，MAC)。
其中，各个端口的配置选择如表1所示。
端口的配置方式
配置方式 端口1-4 端口5 端口6 端口7 端口8
0 100BT1 100BT1 Tx SGMII xMII/GMII
1 100BT1 xMII Tx SGMII xMII
2 100BT1 100BT1 xMII SGMII xMII
3 100BT1 100BT1 Tx xMII xMII
其中，xMII表示SGMII或GMII(Gigabit Medium Independent Interface，千兆媒体独立接口)或MII。
其中，集成了以太网物理层的Q5050芯片的引脚的示意图，如图10所示。以以太网交换芯片为Q5050芯片为例，采用两片Q5050芯片级联的方式来实现以太网功能，第一片芯片采用的配置方式为第2种，第二片芯片采用的配置方式为第3种。其中，两片Q5050芯片串行连接的示意图如图11所示。通过这种方式，可以实现拥有10个100Base-T1的端口(用于仪表，后排PAD，车内摄像头等有大数据流的地方)和1个100Base-TX的端口(预留的车载诊断口)，还有两个同时还有三个支持1000M以太网的RGMII端口。这三个端口一个可以接一片MCU用于信息安全加密，一个可以用来接多媒体，另一个预留。例如在仪表和中控多媒体设备的交互中，中控多媒体设备连接的是其中一个RGMII端口，通过一个USB转千兆以太网的芯片将PAD接入网关的以太网端口，仪表接的是其中一个100Base-T1端口，从而可以实现中控多媒体设备、网关、仪表之间的交互。
图12是本公开一个具体实施例的基于车载以太网的信息交互系统的结构示意图。其中，该系统中包括控多媒体设备、行车记录仪、仪表、全景影像设备、机器人、中排1、中排2、诊断设备、后备箱摄像头、后排1和后排2组成，其中，图12中的控多媒体设备、行车记录仪、仪表、全景影像设备、机器人、中排1、中排2、诊断设备、后备箱摄像头、后排1和后排2均通过接插件与车载以太网网关连接。
其中，图12中的中排1表示中排座椅1上的车载多媒体设备，中排2表示中排座椅2上的车载多媒体设备，后排1表示后排座椅1上的车载多媒体设备，后排2表示后排座椅2上的车载多媒体设备。

在本实施例中，中控多媒体设备110通过无线通信模块(例如4G通信模块)从服务器中获取烧写文件，并通过车载以太网网关120将烧写文件发送到对应的设备，对应的设备根据烧写文件实现更新。
其中，车辆与服务器交互过程的示意图，如图13所示。
为了实现上述实施例，本公开还提出了一种车辆。
