Embodiment 1

[0041] Such as figure 1 As shown in the figure, the central control display virtual expansion screen is built in the car entertainment operating system, and the corresponding framebuffer is created, and then the interface that needs to be interacted is synthesized and written into the framebuffer for transmission.

[0042] The Hypervisor provides an interactive channel between the vehicle entertainment operating system and the instrument display system, creates a communication mechanism for transmitting the physical address of the framebuffer, an asynchronous notification mechanism for image information control, a real-time image information synchronization signal, and a heartbeat notification mechanism for synchronously waiting image keep-alive information; In the embodiment, based on the Hypervisor system, the above-mentioned mechanisms solve the problem of dual-screen display interaction. By passing the physical address of the framebuffer of the virtual expansion screen disp...

Embodiment 2

[0064] Such as figure 2 As shown, a method and system for dual-screen interaction based on the Hypervisor intelligent cockpit operating system, is characterized in that it includes:

[0065] The core processor starts two operating systems through Hypervisor virtualization technology, namely the car entertainment operating system and the instrument display operating system;

[0066] The vehicle entertainment operating system is used to generate the central control display content of the vehicle entertainment application and the interactive display content of the vehicle instrument;

[0067] The central control display is connected with the vehicle entertainment operating system to display the vehicle entertainment application interface;

[0068] The virtual expansion screen of the central control display is generated by the vehicle entertainment operating system and is used to display the content interacted with the instrument display screen;

[0069] The instrument display ...

Abstract

The invention discloses a double-screen interaction method based on a Hypervisor intelligent cockpit operating system. The method comprises the following steps: constructing a central control displayvirtual extension screen end at the central control display touch screen end; creating a frame buffer physical address corresponding to the central control display virtual extension screen, synthesizing a central control display virtual extension screen end display interface and an instrument display screen end display interface which need to be interacted, and writing the synthesized interfaces into the frame buffer physical address for transmission; utilizing a Hypervisor system to create a communication mechanism used for transmitting the framebuffer physical address, an asynchronous notification mechanism used for image information control, a real-time image information signal synchronization mechanism and an image keep-alive information heartbeat notification mechanism used for synchronous waiting. According to the method, one processor is adopted, on the basis of the Hypervisor virtualization technology, two screens of the double systems are achieved, an additional hardware physical connection mode is not needed, meanwhile, the function of displaying image information by an independent application is started, a double-screen interaction mode is achieved, and the hardware costof the intelligent cockpit operating system is reduced.

Description

technical field [0001] The invention belongs to the technical field of virtual machines, and in particular relates to a method and system for dual-screen interaction based on a Hypervisor intelligent cockpit operating system. Background technique [0002] A hypervisor is an intermediate software layer running between a basic physical server and an operating system, allowing multiple operating systems and applications to share hardware. The hypervisor can also be called a virtual machine monitor (virtual machine monitor, VMM). Hypervisors are a "meta" operating system in a virtual environment that has access to all physical devices on a server including disks and memory. Hypervisors not only coordinate access to these hardware resources, but also impose protection between each virtual machine. When the server starts and executes the hypervisor, it loads the operating system of all virtual machine clients and allocates the appropriate amount of memory, CPU, network and disk t...
