The invention relates to the technical field of automobiles, particularly provides a multi-screen display system, an intelligent cabin and a vehicle, and aims to solve the problems of how to optimize resource configuration of the multi-screen display system and how to safely deal with an accidental black screen of a central control screen. In order to achieve the purpose, the method comprises the steps that on the basis of a Hypervisor system of QNX + Android, a double-graphic-engine display framework based on an LVGL engine and a native graphic engine of an Android operating system is constructed; the lightweight LVGL engine is deployed on the QNX operating system, so that the software resource overhead and cost are reduced, the running load of the QNX real-time operating system is reduced, and the timeliness and safety are further improved. Moreover, a layer of keep-alive interface drawn by an LVGL engine deployed by the QNX operating system is added to the central control screen, so that the blank screen phenomenon of the central control screen caused by crash of the Android operating system can be effectively prevented, panic and anxiety of a user are avoided or relieved, the driving safety is further guaranteed, and the user experience is improved.

    本申请涉及汽车技术领域,具体提供一种多屏显示系统、智能座舱及车辆,旨在解决如何优化多屏显示系统的资源配置,及如何安全处置偶发的中控屏黑屏的问题。为此目的,本申请的方法包括:在QNX+Android的Hypervisor系统基础上,构建了基于LVGL引擎+Android操作系统的原生图形引擎的双图形引擎显示构架。通过将轻量化的LVGL引擎部署在QNX操作系统上,不但降低了软件资源开销和成本,还减少了QNX实时操作系统的运行负载,进一步提升了时效性和安全性。并且,在中控屏增加一层由QNX操作系统部署的LVGL引擎绘制的保活界面,可以有效预防Android操作系统出现崩溃时造成的中控屏黑屏现象,避免或减轻了用户恐慌和焦虑,从而进一步保障了行车安全,提升了用户体验。
