Mobile Terminal Of Vehicle Auxiliary System Based On Rough Set

In the development process of automobile, driving assistance systems is always a very important part of car users. In recent years, with the rise of intelligent products, all kinds of intelligent products emerge in an endless stream. Because of the popularity of Android embedded system, let people into a new era of intelligent. A series of intelligent products launched by intelligent mobile phone, such as TVs, cameras, refrigerators, Tablet PC, eyewear, watches and even shoes are implemented intelligent features. Car as a human essential transportation tool, take the road of the intelligent is the general trend.The combination of traditional car recorder, plus vehicle maintenance, repair functions and the advantage of mobile Internet information, this study puts forward the research of assistant system for mobile terminal to use in the car.The traditional automotive auxiliary systems analysis the vehicle traveling data. Compared to the knowledge in the knowledge base, if it is the danger signal, the auxiliary system will warn the driver to pay attention to safety. In this paper, the car auxiliary system is based on the traditional car recorder basis of three main functions:(1) the car alarm;(2) the vehicle maintenance;(3) the vehicle diagnosis. Take advantage of the mobile Internet information superiority, intelligent mobile phone equipped with faster speed and bigger capacity, and puts forward the research about assistant system for mobile terminal using in the car, now in the global popular intelligent era, intelligent vehicle is represent the general trend. The traditional rough set theory simply divide knowledge to the hard classification, analysis results are of three types:(1) Conclusion is certainly correct;(2) Conclusion is certainly incorrect;(3) Conclusion may be correct or may be incorrect. The first two results belongs to the clearly set, and the third results belongs to the rough set, the third results should be removed in the rough set theory knowledge. The third case classified by the rough set will add a degree of membership, the degree of membership can show the credibility of the knowledge, so that the characteristics of the knowledge has been retained rather than discarded. Finally, the system architecture design describes the construction of a knowledge base, the inference engine design and the design of the database table.
