Research And Implementation Of Extended IVI Desktop System And Local Function Based On HTML5

With the development of automobile technology and Internet technology, vehicle information and entertainment system (IVI) has become a new trend of the development of modern automobile. In the present for a large number of technical development of intelligent IVI system, HTML5has become the preferred technique, it can not only complex HMI used to develop systems, but also management development costs. However, there is no better man-machine interface for the user to the HTML5desktop system of management and the numerous Web App, Hybrid App, and HTML5in particular to system based on local feature layer and hardware layer application problems restricted the development of vehicle entertainment system. In the dissertation, the IVI desktop system HTML5and local function based on extended to study, in order to achieve the HTML5application in the IVI system problems. If we build an HTML5-based desktop systems, while solving HTML5own local extensions problem, bound for car manufacturers to win more consumer recognition, and with the development of the automotive industry and mobile technology in a wide range of vehicle systems application, it will become car entertainment systems an important direction for future development.Firstly, through the vehicle IVI and HTML5technology development status of research, combined with the car and the overall structure of the system functional requirements, the dissertatio describes the design ideas and the overall architecture. In IVI desktop implementation aspects using JavaScripe+HTML5+CSS3, in IVI desktop task scheduling application of the main interface, multi-task management, the variety of UI interactions and apply special effects and other ways to make the desktop system main interface with the switching between tasks, return, jump turn, scheduling and other functions. Expansion in the local functional mechanisms established by introducing local NPAPI extensions mechanism to provide car HTML5desktop access to the underlying system capabilities, expanded features include Bluetooth detection, system access, the underlying dynamic library loading, information sharing and transfer, and to achieve the IVI system Bluetooth phone functions.Finally, the dissertatio gives the test results of extended function based on the HTML5desktop system and local features, this paper summarizes the work, and points out the deficiencies of the system, and the next step of work put forward.
