图1是根据本发明实施例的车辆中的控制方法的示意性流程图。
具体地，控制方法100可以由车辆主板执行。
如图1所示，控制方法100可以包括如下内容：
步骤110，在车辆启动的过程中，车辆主板与显示屏进行数据传输，向显示屏输出车辆的车辆状态信息。
其中，在车辆启动过程中，车辆主板能够快速响应，及时与显示屏进行数据传输，使得显示屏显示车辆的车辆状态信息，使得车辆用户能够体验到与传统车辆中设置的仪表盘一样的快速显示。
步骤120，车辆主板从车辆的核心板接收指示信息，指示信息用于指示核心板已完成启动。
步骤130，车辆主板通过显示屏切换器控制核心板与显示屏进行数据传输，其中，核心板包括车载通信模块和/或车载多媒体模块，核心板向显示屏输出的信息包括车载通信模块的通信相关信息和/或车载多媒体模块的多媒体信息。
本发明实施例对通过显示屏切换器控制核心板与显示屏进行数据传输 的具体方式不作限定，例如，车辆主板可以向显示屏切换器发送指令，该指令可以用于指示将车辆主板与显示屏之间的数据传输切换为核心板与显示屏之间的数据传输。
车辆主板的响应速度比核心板的响应速度快。例如车辆开始启动后大约2秒车辆主板即可控制显示屏显示车辆主板输出的信息，车辆开始启动后大约7秒核心板开始正常运行，显示屏显示的内容从车辆主板输出的信息切换为核心板输出的信息。
本发明实施例的控制方法中，在车辆启动过程中车辆主板与显示屏进行数据传输，向显示屏输出车辆的车辆状态信息，然后在核心板已正常启动之后，通过显示屏切换器控制核心板与显示屏进行数据传输，使得显示屏先显示车辆主板输出的车辆状态信息，然后显示核心板输出的通信相关信息和多媒体信息，在保证车辆用户的行车安全的同时，还能够满足车辆用户在行车过程中的通信和/或娱乐需求，从而提升用户的行车体验。
可选地，控制方法100还包括：在核心板与显示屏进行数据传输的过程中，车辆主板确定核心板是否发生故障；在确定核心板发生故障的情况下，车辆主板与显示屏进行数据传输。此时，显示屏显示的内容从核心板输出的信息切换为车辆主板输出的信息。
可选地，车辆主板确定核心板是否发生故障，包括：车辆主板接收核心板发送的状态信号，状态信号用于指示核心板的运行状态；车辆主板根据状态信号，确定核心板是否发生故障。
可选地，车辆主板根据状态信号，确定核心板是否发生故障，包括：当状态信号指示核心板异常，或者车辆主板在预设时间内未接收到状态信号时，车辆主板确定核心板发生故障。
可选地，车辆主板还可以在接收到核心板发送的重启请求时，确定核心板发生故障。
由于核心板上运行的操作系统可能不稳定，因此车辆主板可以定期向核心板发送查询信息，以确定核心板是否正常运行。例如，车辆主板可以定期向核心板发送状态检测信号。核心板也可以主动向车辆主板上报工作状态，例如定期向车辆主板发送状态信号。也就是说，车辆主板接收到的 状态信号可以是核心板根据车辆主板发送的状态检测信号发送的，也可以是核心板主动发送的。在一些实施例中，状态信号可以为心跳信号。
如果核心板正在与显示屏进行数据传输时，核心板发生故障，则车辆主板与显示屏进行数据传输，使得显示屏显示的内容从核心板输出的信息切换为车辆主板输出的信息，能够保证车辆用户的视觉一贯性，提升用户体验。
可选地，控制方法100还可以包括：在确定核心板发生故障的情况下，车辆主板控制核心板重新启动。
可选地，控制方法100还可以包括：车辆主板向核心板发送车辆的车辆状态信息。此时，核心板还向显示屏输出车辆的车辆状态信息。这样能够将车辆的车辆状态信息同步到核心板上，以保证在显示屏显示核心板输出的信息的情况下，仍显示车辆的车辆状态信息。也就是说，显示屏上一直能够显示车辆的车辆状态信息，这样有利于行车安全。
可选地，车辆主板包括倒车雷达模块和/或倒车影像模块。相应地，控制方法100还可以包括：在核心板与显示屏进行数据传输的过程中，车辆主板确定车辆是否准备倒车；在车辆准备倒车的情况下，车辆主板通过倒车雷达模块和/或倒车影像模块向显示屏输出倒车信息。
车辆准备倒车时，倒车影像或倒车雷达启动，车辆主板与显示屏进行数据传输，显示屏显示的内容切换为车辆主板输出的信息，其中车辆主板输出的信息还包括车辆的倒车信息，如倒车影像或倒车雷达指示。
这样能够及时为车辆用户提供倒车影像和/或倒车雷达指示，有利于行车安全。
可选地，控制方法100还可以包括：
在车辆主板与显示屏进行数据传输的过程中，车辆主板接收第一操作指令；
车辆主板确定第一操作指令对应的至少部分操作需要由核心板执行；
车辆主板将第一操作指令转换成适于核心板处理的第二操作指令；
车辆主板向核心板发送第二操作指令。
可选地，控制方法100还可以包括：
在核心板与显示屏进行数据传输的过程中，车辆主板接收核心板发送的第三操作指令，第三操作指令是核心板根据接收到的第四操作指令得到的，第四操作指令对应的至少部分操作需要由车辆主板执行；
车辆主板根据第三操作指令执行相应的操作。
具体地，核心板与显示屏进行数据传输的过程中，核心板可接收第四操作指令，在确定第四操作指令对应的至少部分操作需要由车辆主板执行时，核心板将第四操作指令转换成适于车辆主板处理的第三操作指令，并发送至车辆主板。
应理解，第一操作指令和第四操作指令可以是通过触摸显示屏、实体按键、麦克风等输入设备输入的。
应理解，如果车辆主板接收到的操作指令对应的操作需要由核心板执行时，车辆主板将该操作指令转换成相应的格式，并转发给核心板。如果该操作指令对应的操作需要显示屏呈现核心板输出的相应信息，则还可向通过显示屏切换器控制核心板与显示屏进行数据传输，使得显示屏显示的内容从车辆主板输出的信息切换为核心板输出的信息。
同样，如果核心板接收到的操作指令对应的至少部分操作需要由车辆主板执行，则核心板将该操作指令转换成相应的格式，并转发给车辆主板。
例如，如果核心板接收到外部命令(例如通过实体按键或触摸显示屏输入的命令)，则核心板将需要由车辆主板处理的命令发送给车辆主板，以使得车辆主板进行相应的处理。反之，如果车辆主板接收到需要由核心板处理的外部命令，如LIN信号，则车辆主板将LIN信号转移为相应按键，发送给核心板，以使得核心板解译按键命令以进行相应的处理。
例如，如果显示屏当前正在播放核心板输出的多媒体视频，核心板接收到“关闭多媒体视频并打开收音机”的操作指令，则核心板将多媒体视频关闭，同时将“打开收音机”的操作指令转换为相应的格式，并发送至车辆主板。车辆主板根据该操作指令打开收音机。应注意，此时可以在显示屏上显示默认设置的其他信息，例如车辆的车辆状态信息。或者，此时车辆主板还可以通知显示屏切换器将核心板与显示屏之间的数据传输切换为车 辆主板与显示屏之间的数据传输，使得显示屏上显示收音机的界面。可以理解，车辆主板输出的信息还可以包括收音机的界面。
应注意，如果车辆主板或核心板执行操作指令对应的操作后，需要另一方更新相应的数据，则车辆主板或核心板还可向另一方发送需更新的数据。
可选地，控制方法100还包括：
车辆主板对升级文件进行校验，确定该升级文件有效；
车辆主板使用经过校验的有效升级文件进行升级。
通过在升级前对升级文件进行校验，能够减少软件升级的错误率。并且能够保证升级过程中发生断电或中断，也可以继续升级。
应理解，控制方法100可应用于图4和图5所示的车辆控制系统中，控制方法100中的车辆主板、核心板、显示屏切换器和显示屏可分别对应于图4和图5所示的车辆控制系统中车辆主板401、核心板402、显示屏切换器403和显示屏404，为避免重复，在此适当省略相关内容。

图4是根据本发明实施例的车辆控制系统的示意图。
如图4所示，车辆控制系统包括：车辆主板401、核心板402、显示屏切换器403和显示屏404。
车辆主板401通过显示屏切换器403与显示屏404进行数据传输，并向显示屏404输出车辆的车辆状态信息。

通过车辆主板401将车辆的车辆状态信息输出至显示屏404进行显示，使得无需在车内设置带有盘刻度、指针等的实体仪表盘，不仅能够节省车内空间，有利于车辆的小型化设计还能够降低成本。
核心板402通过显示屏切换器403与显示屏404进行数据传输，核心板402包括车载通信模块和/或车载多媒体模块，并向显示屏404输出车载通信模块的通信相关信息和/或车载多媒体模块的多媒体信息。

本发明实施例的车辆控制系统中，显示屏404既可以显示车辆的车辆状态信息，也可以显示通信相关信息和/或多媒体信息，使得车辆用户的观看更加方便，而且有利于车辆的一体化以及小型化设计。
车辆主板401可以通过低电压差分信号(Low Voltage Differential Signal，简称LVDS)串行器与显示屏404进行数据传输，并通过显示屏404的解串器解串要显示的车辆主板401输出的信息，并在显示屏404上显示出来。核心板402也可通过LVDS串行器与显示屏404进行数据传输，并通过解串器解串要显示的核心板402输出的影音娱乐和/或无线通信相关的信息。应理解，LVDS串行器可以设置在车辆主板401上，作为车辆主板401的一部分。

应理解，车辆主板401和核心板402不能同时与显示屏404进行数据传输。在某一时刻，显示屏切换器403允许车辆主板401与显示屏404进行数据传输，或者允许核心板402与显示屏404进行数据传输。
车辆主板401与显示屏404进行数据传输的情况下，显示屏404上显示车辆主板401输出的信息。核心板402与显示屏404进行数据传输的情况下，显示屏404上显示核心板402输出的信息。
显示屏404显示的内容进行切换，能够根据车辆用户的需求在显示屏404上呈现相应的内容，保证用户的体验。
车辆主板401与显示屏404进行数据传输的情况下，车辆主板401还可以接收显示屏404的输入。应理解，这种情况下车辆主板401还可以接收其他装置或设备的输入，例如麦克风的语音输入、机械按键或旋钮的输入等。
核心板402与显示屏404进行数据传输的情况下，核心板402还可以接收显示屏404的输入。应理解，这种情况下核心板402还可以接收其他装置或设备的输入，例如麦克风的语音输入、机械按键或旋钮的输入等。
本发明实施例中，车辆主板401上的器件可为车规级器件，响应速度快且能够保证更好的稳定性和安全性。核心板402上的器件可以为工业级器件，也可以为车规级器件。应理解，在本发明实施例中，相对于核心板402而言，车辆主板401的响应速度可以更快，且具有更好的稳定性和安全性。
可选地，显示屏404的数量可以为1。设置一个显示屏404能够进一步节约车辆控制系统占用的车内空间。本发明实施例中，由于传统仪表盘的信息和影音娱乐导航等信息都显示在一个显示屏404上，通过本发明的实施例的显示屏切换器403可以无缝切换车辆主板401(负责仪表盘信息)和核心板402(负责影音娱乐导航等)对显示屏404的接管权。
可选地，核心板402与车辆主板401相连接，车辆主板401还可以向核心板402发送车辆的车辆状态信息，核心板402向显示屏404输出的信息还可以包括车辆的车辆状态信息。相应地，在核心板402与显示屏404进行数据传输的情况下，核心板402还可以向显示屏404输出车辆的车辆状态信息。
在一些实施例中，核心板402可以同时向显示屏404输出车辆的车辆状态信息、通信相关信息和多媒体信息。
这样，在显示屏404显示核心板402输出的信息的情况下，仍然能够显示车辆的车辆状态信息。也就是说，无论显示屏404是与车辆主板401进行数据传输，还是与核心板402进行数据传输，由于车辆主板401将车辆状态信息同步给核心板402，因此，显示屏404上一直能够显示车辆的车辆状态信息，这样能够使车辆用户随时获取车辆的行驶状态，有利于行车安全。
具体地，可以在显示屏404的不同预设区域分别显示不同的内容。例如，在显示屏404的某区域上显示核心板402输出的导航地图时，可以在显示屏404的其他区域(如边缘区域)显示车速、挡位等车辆的车辆状态信息。
车辆主板401和核心板402可以使用不同的操作系统。例如，车辆主板401可以使用Linux系统，核心板402可以使用安卓(Android)、iOS等操作系统。
可选地，核心板402还可以包括车载空调(Air Conditioner，简称AC)控制模块。核心板402可以控制车载空调控制模块对车辆的车载空调进行控制。相应地，核心板402还可以向显示屏404输出空调控制界面的信息，这样车辆内的驾驶员或乘客能够通过显示屏404上显示的空调控制界面控制空调。
在传统车辆中通过车辆内部安装的机械按钮和旋钮等来实现空调控制，而在本发明实施例中，将AC控制放置于核心板402，不仅能够减少机械按钮和旋钮占用的空间，还能够满足车辆用户对空调控制的个性化需求，相对于传统的机械按钮和旋钮所能实现的功能更加强大和便捷。
可选地，车辆主板401还可以包括车载收音机。车载收音机是比较常用的娱乐设备，将车载收音机放置在更稳定、响应速度更快的车辆主板401上，能够提供更好地用户体验。另外，由于核心板402上自带收音机功能可能会受到无线带宽和信号等的限制，因此在车辆主板401上设置收音机能够避免收音机功能受到无线带宽和信道等的限制，从而能够实现更好的收听效果。
可选地，车辆主板401还可以包括倒车雷达模块和/或倒车影像模块。将倒车雷达模块和/或倒车影像模块设置在车辆主板401上，能够及时地为用户提供倒车提示，有利于用户体验和行车安全。其中，倒车影像模块包括倒车影像辨识系统(reverse image recognition system)。
相应地，在核心板402与显示屏404进行数据传输的过程中，车辆主板401确定车辆是否准备进行倒车，在确定车辆准备倒车的情况下，车辆主板401通过倒车雷达模块和/或倒车影像模块向显示屏404输出倒车信息。
此时，显示屏404显示车辆主板401输出的信息，其中车辆主板401输出的信息还包括车辆得倒车信息，如倒车影像或倒车雷达。由于车辆主板401可使用车规级芯片，更具有稳定性、安全性和及时性，因此可以将屏幕快速地切换为倒车影像或倒车雷达的提示画面。
可选地，车辆主板401还可以包括车载处理器、车载总线接口、车载电源管理模块、行车记录仪、器件族、升级模块、引擎控制模块、车载视频解码器和车载功放模块中的至少一种。
车载处理器可用于控制车辆主板401上的各个模块执行相应的操作，还可用于处理各个模块输入的信息。车载处理器包括但不限于中央处理器(Central Processing Unit，简称CPU)、数字信号处理器(Digital Signal Processor，简称DSP)、图形处理器(Graphics Processing Unit，简称GPU)和微控制单元(Microcontroller Unit，简称MCU)。例如，GPU可以处理视频解码器输入的信号，DSP可以处理车载收音机输入的音频信号，MCU可以处理机械按键输入的信号。
车载总线接口包括但不限于CAN总线接口和LIN总线接口。
通过将需要快速响应的车规级的电路模块设置在车辆主板401上，能够保证车辆的行车安全，并提升车辆用户的体验。
可选地，显示屏404为触摸显示屏。可选地，核心板402还可以包括触摸显示屏控制模块，触摸显示屏控制模块能够控制触摸显示屏404的操作。
应注意，本发明实施例中的车辆主板401和核心板402上可以不设置内置音箱。车辆主板401上的车载功放模块可以与设置在车辆内部、车辆控制系统外部的外置音箱相连，其中外置音箱可以包括行驶前部的左右喇叭和/或行驶后部的左右喇叭。
可选地，车辆主板401与核心板402相连。车辆主板401上的车载处理器与车载功放模块可以处理来自车辆主板401上的收音机的音频输入和来自核心板402的音频输入，并将音频输出到外置音箱。
本发明实施例中，可以将需要快速响应的电路模块设置在车辆主板上，而无需快速响应的车载多媒体模块、车载通信模块和空调控制模块等设置在核心板402上，这样不仅可以平衡车辆主板401和核心板402的计算资源、安全性和响应时间，同时还能够提供稳定、安全、舒适的用户体验。
如果将所有的电路模块都分布在车辆主板401上，则要求该车辆主板401上的电路模块都满足车规级硬件电路的要求，会导致消耗更多的硬件资源。如果将各个电路模块都分布在核心板402上，则可能出现死机或出错，从而造成安全隐患。而本发明实施例将车辆主板401和核心板402结合，合理地分配车辆驾驶和娱乐过程中的所需的各个电路模块，能够避免上述问题，从而在保证安全性的前提下使得车辆用户获得良好的驾驶和娱乐体验。
可选地，核心板402和车辆主板401分别与设置在车辆内部、车辆控制系统外部的麦克风相连。应理解，麦克风可以设置在车辆内的任何位置，例如麦克风可以设置在车辆的顶棚上。核心板402和车辆主板401分别根据麦克风输入的语音指令执行相应的操作。具体地，车辆主板401和核心板402可以分别将语音指令转换成文字或指令或其他内容，并显示或 执行相应的操作。这样，使得用户可以通过麦克风输入语音指令来进行各种操作，例如文字输入、空调控制、打开收音机，以及对车辆的控制(例如打开车灯)等。
可选地，在车辆启动的过程中，车辆主板401与显示屏404进行数据传输。在车辆正常运行过程中，核心板402与显示屏404进行数据传输。在一些实施例中，核心板402与显示屏404进行数据传输时，核心板402处于正常运行状态。
可选地，在核心板402与显示屏404进行数据传输的过程中，车辆主板401确定核心板402是否出现故障，并在确定核心板402出现故障的情况下，车辆主板401与显示屏404进行数据传输。此时，显示屏404显示车辆主板401输出的信息。
例如，车辆主板401还可以在确定核心板402出现故障、无法正常工作的情况下，控制显示屏切换器403将核心板402与显示屏404之间的数据传输切换为车辆主板401与显示屏404之间的数据传输。相应地，显示屏404显示的内容从核心板402输出的信息切换为车辆主板401输出的信息。
可选地，车辆主板401还可以以预定时间间隔向核心板402发送状态查询消息，在核心板402应答无法正常工作、或核心板402超时无应答、或车辆主板401接收到核心板402发送的要求重启的请求的情况下，车辆主板401确定核心板402出现故障无法正常工作。如此，车辆主板401可以随时掌握核心板402的工作状态，以便随时在核心板402不能正常接管显示屏404的屏幕显示时，接管该显示屏404的屏幕显示，同时保证用户的安全性和娱乐性的体验。
在车辆主板401与显示屏404进行数据传输的情况下，车辆主板401还可以接收显示屏404的输入。而且，当车辆主板401接收到显示屏404的输入、并确定该输入应由核心板402处理时，可将该输入转换为核心板402理解的命令形式，并传输给核心板402以便核心板402进行相应动作。在核心板402与显示屏404进行数据传输的情况下，核心板402还可以接收显示屏404的输入。而且，当核心板402接收到显示屏404的输 入、并确定该输入应由车辆主板401处理时，可将该输入转换为车辆主板401理解的命令形式，并传输给车辆主板401，由车辆主板401进行相应动作。
应理解，车辆主板401和核心板执行的操作指令不同，例如核心板处理有关通信服务、触摸屏、导航、蓝牙、多媒体、AC控制等操作指令，而车辆主板401接收有关收音机、倒车雷达、倒车影像、行车记录仪、软件升级等操作指令。例如车辆主板401可以处理如下收音机相关的操作，如音量、音效、音场、和/或音源等的调节。因此，如果车辆主板401和核心板402各自接收到的操作指令对应的操作需要由另一方反馈或动作，则可以将该操作指令转换成相应的格式并转发至另一方。这样能够实现车辆主板401和核心板402之间的信息交互。
图5示出了本发明实施例的车辆控制系统的一个例子。
如图5所示，核心板402可以包括短距离无线通信模块、车载多媒体模块、车载导航模块、移动通信模块、电源接口、麦克风接口，车辆主板401可以包括功放模块、DSP、LVDS串行器、电源管理单元(Pressure Measuring Unit，简称PMU)、电源接口、视频解码器、CPU、MCU、收音机、麦克风接口、按键接口、LIN接口、CAN接口。
核心板402还可以包括通信天线接插头和GPS天线接插头(图5中未示出)，车辆主板401还可以包括收音机天线接插头(图5中未示出)。
如图5所示，显示屏切换器403可以设置在车辆主板401上。这样能够进一步减小占用的空间。在一些实施例中，显示屏切换器403也可以作为车辆主板401的一部分。
核心板402可以设置在车辆主板401上。将核心板402叠加设置在车辆主板401上能够进一步减小占据的空间，有利于小型化设计。应理解，图5仅是示意性的，核心板402可以叠加设置在车辆主板401上的任意位置。
可选地，车辆主板401和核心板402可以通过板对板连接器(Board-to-board Connectors，BTB连接器)相连。车辆主板401和核心板402之 间可以通过板对板连接器进行通信。
具体地，核心板402和车辆主板401通过2个板对板连接器相连。当然，核心板402和车辆主板401还可以通过其他数量的多个板对板连接器相连，本发明实施例对此并不限定。例如，核心板402和车辆主板401还可通过4个板对板连接器相连。
可选地，每个板对板连接器可以为40脚(pin)板对板连接器。
应理解，核心板402和车辆主板401中还可以包括图5中未示出的其他模块。
