At the same time, the sensor technology is also engaged in an equally significant revolution. At present, the vast majority of senior security sensor systems are used, they were assembled in the internal body, to track the steering tire, brake pressure, the steering wheel drivers to speed, and so on. But the next generation sensors (including radar and hidden photographic head) will be distributed in the body outside, a vehicle monitoring the external environment of an eye.

It is worth mentioning that these advanced digital technology from ordinary cars to luxury models, such as the Ford Motor Company of a small truck through the seat of the device can measure the weight of each passenger, if found seated in the front row Co-location of a child, the airbags will be automatically shut down the function (because the air bags will be keen to open his head against the children, not only will not be safe, but easy to hurt the children).

However, the use of digital technology in enhancing vehicle safety in the process, there is a paradox: the large number of digital technology used to improve safety braking performance, while also using more hardware and software, which increases the system Complex, which is a new hidden danger. Recently the number of the world's car companies to recall the vehicles increase, much of this contradiction is caused. Auto makers have held that: the introduction of new technology get more advantages than disadvantages.

Adaptive cruise control
Nearly every major car manufacturers are already using electronic stability system, once when the driver lost control, this system will tire of each respective control and stability. But this is not the most advanced.

Many of the luxury cars like the Cadillac XLR as the automatic cruise control systems that can automatically when the front brake obstacles suddenly. A few years later, this system will appear in a large number of vehicles on the streets, especially in high-speed road incidents can be avoided when a large number of cars in a chain collision. General Motors and other companies are developing a different frequency radar transceiver, can be early warning system in the communication between the vehicles to achieve coordination of distance between vehicles, collision avoidance purposes. Some of these technologies is expected to be in five to ten years a large number listed.

Can autopilot dream come true?
An engineer and car magazine editor thought that the development of automobile technology is the ultimate realization of fully automatic driving. He said that in the past people have always been this dream will be strongly dependent on the use of a lot of technology, investment alarming a highway, but now with GPS satellite positioning, radar cruise, the direction of adjustment system, different frequency radar transceiver and first-class camera technology And a combination of maturity, on the road in general, the traditional vehicle traffic in an automatic driving a car more and more feasible.
