Device and method for for displaying multimode application on vehicle-mounted air conditioner screen

Abstract

The invention provides a device for displaying a multimode application on a vehicle-mounted air conditioner screen. The device comprises: a hardware platform shared by multiple operating systems, andat least one air conditioner screen; a virtual machine manager which runs on the hardware platform; an air conditioner operating system which runs on the virtual machine manager, and a central controlmultimedia entertainment operating system which runs on the virtual machine manager. The virtual machine manager includes: a resource allocation module, a system scheduling module and a display layersuperposition processing module; the display layer superposition processing module is used for superposing the display layer data of the air conditioner operating system and the display layer data ofthe central control multimedia entertainment operating system to form synthesized display layer data, and displaying the synthesized display layer data on the air conditioner screen. The invention further provides a corresponding method. By means of the device and method, information interaction between the air conditioner system and the central control multimedia entertainment system can be achieved on one air conditioner screen, and the internet entertainment ecological function can be achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted virtual machines, in particular to a device and method for realizing multi-mode application of vehicle-mounted air-conditioning screen display. Background technique [0002] With the development of intelligent networking of smart cockpits, the integration of multiple ECUs (electronic control units) and multi-operating systems is the development direction of future smart cockpits, in order to improve the communication efficiency between ECUs and save hardware costs and assembly space. [0003] For example, in some existing examples, the instrument domain and the air-conditioning functional domain share one ECU and operating system; or the central control multimedia entertainment system domain and the air-conditioning functional domain share one ECU and operating system; or the air-conditioning functional domain uses one ECU and operating system; [0004] However, these existing solutions h...

AI Technical Summary

Problems solved by technology

[0004] However, these existing solutions have more or less deficiencies. For example, in the solution where the instrument domain and the air-conditioning functional domain share the same ECU and operating system, there is a lack of ecological resources such as the integration of Internet entertainment ecology on the air-conditioning screen. There is a problem of information delay in information interaction with the multimedia entertainment system domain;

[0005] In the solution where the central control multimedia entertainment system domain and the air-conditioning functional domain share the same ECU and operating system, the start-up speed is slow (for example: about 20S), which cannot meet the needs of users to turn on and adjust the air-conditioning immediately after getting in the car; while the air-conditioning functional domain In the solution of using one ECU and operating system alone, the integrated Internet entertainment ecological function has ecological deficiency, or there is a problem of slow startup speed and high cost
