The method shown in Fig. 1 is applied to a vehicle. The vehicle includes an infotainment operating system and a real-time operating system. When the vehicle is started, the infotainment operating system and the real-time operating system The operating system is deployed in different virtual machines, and application programs are also deployed in the virtual machine where the infotainment operating system is located, and the method includes:
在步骤101中，通过信息娱乐操作系统获取应用程序的渲染后的待显示数据，并将渲染后的待显示数据置于虚拟共享内存中。In
信息娱乐操作系统所在的虚拟机中还部署有应用程序，该应用程序可以是仅针对仪表盘显示屏设置的程序，即应用程序的渲染后的数据仅在仪表盘上显示，这时信息娱乐操作系统所在的虚拟机中还部署有其他应用程序，其他应用程序的渲染后的数据在中控显示屏上显示。An application program is also deployed in the virtual machine where the infotainment operating system is located. The application program can be a program set only for the dashboard display, that is, the rendered data of the application is only displayed on the dashboard. At this time, the infotainment operation Other applications are also deployed in the virtual machine where the system is located, and the rendered data of other applications is displayed on the central control display.
或者，该应用程序可以是针对仪表盘显示屏和中控显示屏设置的程序，在一定条件下，应用程序的渲染后的数据可以仅在仪表盘显示屏上显示，可以仅在中控显示屏上显示，或者可以同时在两个显示屏上显示。Alternatively, the application may be a program set for the instrument panel display and the central control display. Under certain conditions, the rendered data of the application may be displayed only on the instrument panel display, or only on the central control display. displayed on the display, or can be displayed on both displays at the same time.

在一个实施例中，车辆还包括图形处理器(Graphics Processing Unit，GPU)、部署在信息娱乐操作系统所在的虚拟机中的图形处理器驱动和第一显示驱动。In one embodiment, the vehicle further includes a graphics processor (Graphics Processing Unit, GPU), a graphics processor driver and a first display driver deployed in the virtual machine where the infotainment operating system is located.
当信息娱乐操作系统中运行了应用程序、第一显示驱动和图形处理器驱动时，车辆可以通过信息娱乐操作系统利用图形处理器驱动，将待显示数据发送给图形处理器进行渲染，以及接收图形处理器发送的渲染后的待处理数据，之后通过信息娱乐操作系统利用第一显示驱动，将渲染后的待显示数据置于虚拟共享内存中。When the application program, the first display driver and the graphics processor driver are run in the infotainment operating system, the vehicle can use the graphics processor drive through the infotainment operating system to send data to be displayed to the graphics processor for rendering, and receive graphics The rendered to-be-processed data sent by the processor is then used by the infotainment operating system to use the first display driver to place the rendered to-be-displayed data in the virtual shared memory.
在一个实施例中，对于信息娱乐操作系统中部署的应用程序，存在多种启动方式。例如，第一种启动方式：在信息娱乐操作系统提供一操作界面，操作界面上显示应用程序的应用图标的情况下，通过信息娱乐操作系统接收针对应用图标的预设触控操作，控制应用程序启动。In one embodiment, there are multiple launch modes for applications deployed in the infotainment operating system. For example, the first startup method: in the case that the infotainment operating system provides an operation interface and the application icon of the application program is displayed on the operation interface, the preset touch operation for the application icon is received through the infotainment operating system, and the application program is controlled. start up.
中控显示屏上可以显示应用程序的应用图标，用户可以通过点击该应用图标，触发应用程序启动。用户可以是车内人员，可以是司机或乘客。The application icon of the application can be displayed on the central control display, and the user can trigger the application to start by clicking the application icon. The user can be a person in the vehicle, a driver or a passenger.
又如，第二种启动方式：通过实时操作系统接收预设控制类型的车辆控制信号，向信息娱乐操作系统发送启动指令，启动指令用于请求启动应用功能与预设控制类型匹配的应用程序，基于启动指令，确定应用功能与预设控制类型匹配的应用程序，启动该应用程序。In another example, the second startup method: receiving a vehicle control signal of a preset control type through the real-time operating system, sending a startup instruction to the infotainment operating system, and the startup instruction is used to request to start an application program whose application function matches the preset control type, Based on the startup instruction, an application program whose application function matches the preset control type is determined, and the application program is started.
例如，通过实时操作系统接收倒车指令，通知信息娱乐操作系统启动相应的程序，触发信息娱乐操作系统启动倒车影像应用。For example, the real-time operating system receives the reversing instruction, informs the infotainment operating system to start the corresponding program, and triggers the infotainment operating system to start the reversing image application.
在步骤102中，通过实时操作系统从虚拟共享内存中获取渲染后的待显示数据，将渲染后的待显示数据显示在车辆中的仪表盘显示屏上。In
