Research On The Automobile Information Interaction And Control System Based On Android

The automobile information interaction and control system includesdriving information system, and in-car entertainment system, alarm systemand auxiliary driving system. In recent years, main car manufactoriesincrease the research investment, which makes the vehicle informationsystem develop greatly. But at present, the domestic and abroad research oncar-info system is still in a relatively closed stage, and all companies developtheir own products in different embedded platform, which lack of widespreadand common platform to support, at the same time for vehicle informationsystem research mainly focus on the entertainment system and auxiliarydriving system. On the other hand, Google provide an open source embeddedsystem which gains broad approval due to its relatively high security andstability in the consumer electronics field. Based on a model as the res earchobject, I set up a remote data interaction and control system, simultaneouslysimulate vehicle condition information with a PC, to achieve datainformation and graphical information real-time transmission.In this paper, the contents and conclusions of the study are as follows:1) This paper set up a server on Windows platform. This servercompletes data encryption and analytical, receiving and transforming,storaging function. And mobile terminal can communicate with the serverwith three different ways, i.e. wifi,3G, Bluetooth. The establishment of theserver contributes to smoothly running of the system.2) This paper has developed a set of standard communication protocoland standard user permissions. Each instruction consists of six data frame,adding the check code in the end of the frame. User permissions is dividedinto six levels by giving different user identity different permissions. Through the landing password matching, the data frame information encryption,divided authority triple encryption. All the encryptions are secretly codeencrypted to guarantee the safety of the system.3) This paper develops a car information interaction and control system,respectively vehicle simulation driving data interaction informationsubsystem, air conditioning control information subsystem, RKE control andalarm subsystem, car information entertainment subsystem and auxiliarydriving subsystem. Each subsystem module is relatively independent, but inalarm trigger points they interrelate with each other together. Through themultithreaded programming way, this paper increase the system’s fluency andplayability.4) The system aims to become a complete set of commercial products.In order to adapt to different ages crowd, the author designs a set of userfriendly interface, through the changing of skin way between differentinterfaces of the version.5) The whole system has been tested and debugged. It has been provedstable and reliable in the Shanghai International Industry Expo in acontinuous operation. This fully illustrates the effectiveness of theinformation interaction and control system established in this paper.
