Although people are looking for intelligent vehicle technology to bring their own more liberation, but must recognize the fact that this road is not smooth
Transformers II came again. The courtyard line on the screen is the hit robot car, appearance, cool and freely.
Many people dream of a robot car then docked in the yard, sitting for a ride. However, if you are on the way to work today, you see a car moving leisurely, and the owner of the car in the car to read the newspaper, what would you do?
"I'll be scared. That's scary." A colleague answers very carefully.
But in fact, in June 3, 2009 to 5 degrees Celsius under the scorching sun, a lot of people in Xi'an to watch China's first smart car challenge in the future of the game, witnessed the driverless car on the road grand occasion of the 35.
Indeed, the use of unmanned vehicles is no longer a science fiction story.
Future prediction
After 8 years of discussion, the National Natural Science Foundation of China, a major research program - audio-visual information cognitive computing project in 2008. This is a collection of information science, life science and mathematical science and other fields of cross research. It is worth noting that, in the overall goal of the project, the fund also hopes to build a platform for the verification of unmanned vehicles. As a result, the Fund Committee and major research programs to guide the panel decided to host China's smart car challenge of the future race.
Unmanned vehicles, also known as intelligent vehicles or wheeled mobile robots, which rely on the computer based intelligent vehicle driver to achieve unmanned. To perceive the environment around the vehicle using the vehicle sensor, and according to the perception of road and vehicle location and obstacle information, control the steering and speed of the vehicle, so the vehicle can safely and reliably on the road.
In fact, drivers are the least controllable and difficult to determine. According to data released by the Ministry of public security, resulting in casualties in traffic accidents, more than 90% are caused by human factors. Unmanned will be the most insecure people banned.
The application of intelligent vehicle can be divided into two categories: fully automated transportation system, that is, all vehicles are automatic driving; mixed traffic system is still part of the vehicle is driving. The former has begun to enter the practical stage, such as Europe's existing short haul low-speed applications and some military applications. Yang Ming, an associate professor at Shanghai Jiao Tong University, said: the latter into the practical phase is still a long way to go, I'm afraid to 10~20 years."
But until now, in the field of intelligent vehicle research, scientists on the prediction of automatic unmanned technology is also controversial.
Chinese automated scientific research institute deputy director Wang Feiyue researcher believes that the drone is a distant thing, he accepted the "science news" interview, said: "after 50 years, the unmanned vehicle can not be used. The future of intelligent driving technology will be very good."
"Today, we have a number of smart cars, and in the next few years, it will certainly grow," said Professor Alberto Broggi of the University of Palma in Italy. About five or six years later, driverless cars will appear, they will travel in a particular section of the road. For example, on the highway, for safety reasons, you can open up to one or two lanes, specifically for driverless vehicles."
Insurmountable intelligence
After struggling, recently had to declare bankruptcy of the General Motors Corporation is the forerunner of the unmanned vehicle, as early as the 1939 New York World Expo, GM will display for the first time the unmanned vehicle concept Futurama.
The initial push for unmanned research was in the military field. U.S. military in the last century in 70s began to focus on unmanned technology. 1995, an unmanned vehicle developed by the Carnegie Mellon University, Navlab-V, completed across the east coast of the United States unmanned test. In the 4587 km long interstate highway, the entire experiment is more than 98.2% of the vehicle driving. National Defense University, Italy, Germany, Palma and other research institutions in the same period were similar tests.
Since the beginning of 80s, China's smart car research and development." National University of Defense Technology professor He Hangen told the "science news" interview, said, "we have started running a test project 2000 km highway, from Beijing to Guangzhou, human intervention will be less than 3%."
These experiments seem to have made it possible for the world to see driverless cars at hand. "We think we'll be using smart cars in the near future, but we're wrong." Broggi said.
The biggest stumbling block on the road to intelligence is the efficiency of these unmanned long-range tests is 95%~98%, when the test vehicle problems, there will always be an experimenter to make up for the next. The best performance of the test is less than 99.9% of driving safety requirements.
