In October 21, 2004 at the automotive electronics conference "Convergence 2004", the United States, with international Matsushita, chairman and CEO of Health summed up the light is concentrating on the development of four major technical fields, they were around the car in environmental protection, safety, comfort And the ease of upgrading. In addition to environmental protection and an IT is not directly linked, and the remaining three are calculated or closely related to communication technologies: security and development to identify obstacles and pedestrian sensing technology to prevent accidents; comfort, through Biological and chemical detection and sensor technology driving the changes in body temperature and heart rate, in order to automatically adjust the car air-conditioning; convenience, to include a new generation of human-machine interface technology, the vehicle navigation instrument display system, the windows on the former Traffic maps show that the information needed to drive the process. Before and after the 21st century, the global IT and set off a wave of car this shows evident.

Maybe you have learned through the popular science knowledge: Today a car, including hundreds of micro-computer system (embedded computers), auto and IT is not a long time between the origins?

The last car on the use of embedded computing technology and rely on, can only be described as its digital (or electronic) start. Present are taking place in the revolution is surging wave of car IT: Digital technology not only for the various bodies within the system control, will be the latest in the various automotive terminal equipment, wireless communications network and remote information services with the support of , Within and outside the vehicle, very thorough "IT affiliation."

This wave is the wave of some scenes are painted texture: just in the car, the driver or passengers through the dashboard next to the electronic screen e-mail, view real-time weather forecasts and other information, was informed that the front section of the traffic congestion; Long journey, through a variety of car entertainment devices to enjoy music, films, television programs and even OK to sing karaoke and playing computer games; advanced radar system to avoid a large number of traffic accidents, even with the road infrastructure to achieve automatic driving And the driver may from time to time to complete rest, in the long-distance driving in comfort and a nap ---these dreams of the past, have now entered the final preliminary practical or pilot phase.

Car satellite TV
In the U.S. market, there is a car antenna system device (KVH TracVision A5), in a moving vehicle can automatically track and receive satellite television signals, said program good enough quality comparable with cable. But the high price in terms of ordinary people, the installation of about 2,500 U.S. dollars, incurring additional 14 U.S. dollars a month in service fees, and vehicle antennas too large, can be an SUV's roof luggage rack filled up (Figure 1). In Japan, the country's broadcasting on the end of October 2004 show by Sharp, Toshiba production of the car TV reception terminals, and bus demonstration of its newly launched mobile TV programs.
