The future automobile you concern about not only the fuel economy, the most important thing is to take you safely to your place. Traffic accidents and rescue are often the topics of our discussion, and conclusions are often reduced to, we need to improve vehicle navigation and safety system. However, it is not easy to solve this problem. For example, although GM's OnStar and the BMW Assist technology can provide great help, they generally need the help of mobile phone communication network. The reality is that in the slightly remote region, mobile phone signals are often not protected.

Fortunately, many car manufacturers and national government departments have been studying some newer technologies, so in case of emergency to provide more effective help for us. These new technologies are mainly concentrated in the new navigation system, emergency braking sensor system and vehicle-vehicle wireless communication system, and so on. In all of these technologies, sensor network will play an important role, and its greatest significance lies in prevention. For example, timely warning car and driver of inclement weather, road control and traffic accident to reduce the possibility of accidents.

The new direction of auto safety and navigation

In the daily work and life, people stay more and more time in the transport. Therefore, the significance to equip auto with more convenient communication facilities is also increasingly important, because it will help us promptly contact with our families and colleagues, it also helps us with the early detection of risk. Moreover, automotive communication device should also be integrated with our common portable communication device, such as mobile phone, PDA, and so on. For these reasons, many experts believe, automotive communication system will soon enter a very rapid period of development.

Automotive navigation system is one of the most mature automotive electronic devices, also the biggest help for drivers, and its price has been reduced to the degree majority of owners are willing to buy. Many people believe that only in-vehicle navigation can be meaningful in unfamiliar areas. This is not the case, because the greatest significance of automotive navigation system is dynamic navigation, which is based on the current road conditions, such as where traffic jammed, where the accident occurred, where traffic control, etc., to help drivers choose the most convenient route. If it is in remote areas, the role of the navigation system to improve security is greater, because of widespread use of satellite communications, mobile phone signals will not be worried about being interrupted. In some places, the population is less dense, if the accident occurred more difficult to seek help. Therefore, in sparsely populated areas, information on the road status and bad weather is more valuable.
