In February of this year, the "Technology View" of the Massachusetts Institute of Technology in the United States predicted that the vehicle-to-Vehicle technology will become the most breakthrough innovation in 2015, and will be in the next 1-2 years. Can be implemented. And this year has not finished, the United States has begun to carry out related projects in several major cities. First, Manhattan and Brooklyn, New York, the local government is building hardware facilities for vehicle-to-infrastructure communication. In another city, Tampa, Fla., the local government invested $17 million to develop V2V technology, and they hope that the technology will enter real life as quickly as possible and help ease traffic congestion in the city. . The workshop communication V2V is simple, that is, without the driver participating in the operation, the car can automatically "talk" to the surrounding vehicles to see their respective driving conditions. The car automatically transmits its own driving information to a few hundred meters in the vicinity through short-range radio technology (DSRC), including: GPS position, speed, steering wheel angle (predicting the vehicle's forward trajectory), brake pedal position and so on. The surrounding vehicles use the information they receive to build an instant dynamic map. In the map, the on-board computer can not only "see" whether there is a car around it, but also predict whether other cars will affect their normal driving, and issue a collision warning to the driver in advance to avoid traffic accidents. happened. Although many cars have already implemented similar functions using equipment such as ultrasonic radar and cameras, because of the limitations of the "observation" range, the effective range of safety systems using radar and other equipment is only a few square meters around the body, and not As with V2V technology, even over-the-horizon information communication can be achieved. But why is a workshop communication technology selected by the Massachusetts Institute of Technology as the most groundbreaking innovation in 2015? An experiment done by the National Highway Traffic Safety Administration and the University of Michigan may explain why. The two units conducted a V2V communication test of nearly 3,000 vehicles between 2012 and 2014. The participating vehicles send their own driving information to the surroundings at a frequency of 10 times per second, and the nearby vehicles make an early warning to the driver before the danger occurs according to the received information. Experimental results show that this technology can prevent more than 500,000 traffic accidents every year, saving more than 1,000 lives. This is why the United States is so anxious to extend this technology to real life. GM plans to use V2V technology in its Cadillac CTS sedan in 2017. In addition to GM, other automakers such as BMW, Toyota and Honda Audi have similar V2V projects. In promoting V2V technology into real life, in addition to technical barriers to communication, information security is also an important issue. How to realize the communication in the workshop, without exposing too much personal information, is also a problem that technicians need to solve as soon as possible. Because of security, it is the most basic attribute of a technology being trusted.
