Implementation Of HMI Subsystem In Vehicle Navigation System

With the abundant development of electronic technology, communication technology and computer technology, the scientists begin to apply the electronic information technology to the traffic system in order to improve the efficiency and security of the transportation more and more, and a special field has been formed finally--"Intelligent Transport System". To intellectualizing the traffic system, the general method is to install an additional vehicle navigation system at present. As an important part of the embedded software, the quality of the embedded HMI effects the embedded production.In this paper, the background information and critical technology about HMI system is introduced firstly. After that, we analyze the feasibility of the system and system architecture design. In this project, I mainly take part in the design and implement of HMImanager module, AUI module, and Application control module, at the same time I analyze deeply and resolve some problems meeted during our developing.Finally, the conclusion and future about the system are given. Moreover we give the all-around appraisal about the system and put forward some suggestions to improving the system.
