Design And Implement Of Vehicle Mounted System Based On The Android

Combined with the advantages of open source android operating system,this paper proposed the design and implement of vehicle mounted system and completed the integration of the tire pressure monitoring system(TPMS)based on the Android to meet the current rapid development of vehicle network technology and the broad market prospect of intelligent vehicle terminal,which brings not only safer,faster driving experience,but also lets them appreciate the advantage of the "Car Life".This system integrates many technologies such as JNI interface development technology,Android development technology and navigation SDK development technology and so on.The system mainly realizes tire pressure monitoring,reverse image,distance scaling,driving record,GPS navigation and multimedia.In the process of development and realization of the system.First,the development board through the GPIO port expansion function module for sensor data signal acquisition;Then,to compile the module driver corresponding JNI interface into dynamic link library file through the NDK cross compiler environment;Finally,to script the layout and the interaction logic of the system software by the android development technology and call to the third-party interface.In addition,using the software testing tools and methods of the system to conduct a comprehensive test to ensure that the functional integrity and stability of the system.At last,this thesis completed a relatively mature and stable vehicle central control system,especially for the solution of how to integrate the TPMS in the Android vehicle system.It makes great research value and practical significance to the vigorous development of the on-board service at home and abroad.To a certain extend push the car networking technology forward.
