Multiscreen independent-operated vehicle information system with novel architecture

Abstract

The invention provides a vehicle multimedia interactive terminal for achieving multiscreen interaction through a creative embedded software and hardware architecture. Man-machine interface capacity is widened for the architecture in hardware, so that a plurality of display, speech, touch and key interfaces are supported; and the traditional embedded operation system is reconstructed on software through a virtual machine technique or a multi-window application framework technique, so that multi-user and multi-window independent task response is supported. Through utilizing the novel embedded architecture, a plurality of touch and key independent operations and a plurality of speech inputs as well as a plurality of screen independent displays and a plurality of sound independent outputs are achieved on an automobile, so that different requirements of a driver and a plurality of passengers in the automobile are satisfied, wherein the screen independent displays and the sound independent outputs correspond to the touch and key independent operations and the speech inputs one to one. By using a unified processing core and shared system resources, on one hand, communication requirements among a plurality of clients are reduced to facilitate the system realization, on the other hand, the system cost is saved and the system is improved.

Description

technical field [0001] The invention relates to the field of vehicle electronics and embedded application technology. Background technique [0002] With the development of the car industry, electronic systems are more and more widely used in cars, especially the car aftermarket because of its openness and standardization, which has attracted many manufacturers to develop on-board electronic equipment. [0003] So far, after-loading vehicle electronic equipment mainly focuses on the traditional audio-visual system based on Digital Versatile Disc DVD (Digital Versatile Disc) and the independent GPS (global position system) navigation system. Although the traditional DVD audio-visual system can provide a good entertainment experience, the lack of functions is also obvious, and the function expansion and device interoperability are insufficient, especially when various electronic devices emerge in an endless stream, and the interoperability of devices is increasingly urgent. pr...
