Development Of Universal Automobile Multimedia Application Integration System

With the development of science and technology, the automobile industry with each passing day, the automobile in people’s lives play an increasingly important role in the demand for automobiles continues to increase, application integration requirements of automotive multimedia system not only an entertainment system, while I hope it is one of the driving lane assist feature safety-critical systems. Automobile multimedia development and market making it a proprietary electronics industry, such as automobile radio, automobile digital TV, automobile MP3, automobile GPS systems, automobile DVD, Bluetooth handsfree, reverse video. This topic is in this environment, research and development of a fully functional automobile multimedia application integration systems, compatible with a variety of automobile electronics applications above and driver assistance features, explore the future trends for motorists to provide convenient and efficient human-computer interaction systems This research constitutes the overall car multimedia application integration system and the overall architecture of each device interface extensions designed so that it can access a variety of automobile driver assistance,traffic safety, anti-theft alarm,parking,panoramic, infrared night vision and other external devices.This topic is designed automotive multimedia application integration system is based on ARM Cortex-M3 processorcoreandthe underlying hardware control bus interface module and display module is based on WINCE systems and video processing chip composition.The main achievement of various audio and video sources automobile radio, DVD, IPOD,TV and other operating data and switching to achieve a GPS navigation, USB playback,Bluetooth hands-free and other applications, but also compatible with tire pressure monitoring, electronic dog alert, reversing radar,infrared night vision and other auxiliary equipment.The system usesa7-inch 800*480 resolution TFT LCD screen and full-size touch screen, handwriting input and implements interactive interface touch operation. Selected high-end audio processing chip, multi-band EQ equalizer settings and a variety of sound modes, dynamic spectrum display.The automobile multimedia achieved CAN, LIN, IEBUS, UART other bus interface, enabling interactive communication with the vehicle network or other vehicle electronic devices, enabling the multimedia information system control and other automotive electronic devices display.
