General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
Drunk? Find and driving or a chance? All need not, get in your car, press the button, unmanned mode the car will automatically put you drove home. Now have? No, but sooner or later, there will be. Beijing time December 15, the United States patent and trademark office to Google awarded a driverless cars patent, patent number is 8078349. The patent document mentioned a hybrid model car, can be in someone driving condition and no one switch between driving condition.In getting the patent before, after Google refitted 7 driverless cars have no human intervention in the case, to be automatic traveled more than 220000 miles, and only happen once by other rear-end collision accident. These driverless cars including refitted Toyota prius and a car audi TT.Google's driverless cars through own sensor to the surrounding environment and road for identification, roof device a rapidly rotating laser rangefinder, it can each position to perform more than 60 m from scanning, obtain the accurate at any time of the 3 d map, and to the vehicle-mounted computer; Body around four radar sensors, used to detect obstacles of distance, the design is become before 3 after 1 layout; Responsible for the evaluation of the positioning position, can monitor vehicles driving on the car DVD GPS maps whether set good line, he was Google's engineers installed in the left rear wheels; The car "eyes" in the car next to the rearview mirror, the camera can "see" the traffic lights, monitoring the pedestrian, bicycles, mobile obstacles. Car collection of the surrounding terrain much of the information related to the over all the data center to deal with Google, and a data center accurately every road of storage speed limits and the export of position, if vehicles in driver's, the data center are given through the speaker "approaching crossroads", "be careful pedestrian" voice commands.Research and development system of course not only unmanned Google a, BMW, general motors, and Volvo company released a similar system. The company introduced a CDC (Connected Drive Connect) system, and has been in five cars test of on. The system through the GPS, radar, ultrasonic and laser detector, camera etc detection equipment receiving data, collected GPS satellite navigation, camera and masp digital cameras to determine the orientation of the vehicle in the driveway, lane number and the driving path ahead. Domestic in driverless cars on the research and development is a major breakthrough, this year July 14, the national defense university of science and technology of the red flag HQ3 independent research and no one car, completed the first from changsha to wuhan 286 kilometers of high-speed whole unmanned experimental, including independent overtaking 67 times, the average speed of 87 kilometers. However, Google in this field has two big advantage, it is starting advantages, its "street view service" system has been shot and store the frame around the world for hundreds of thousands of road conditions images, including related the road surface logo. The other is a capital advantage, in 2009, Google into research and development spending as much as us $2.8 billion, accounting for 12% of revenue in the company, such big let other company elusive.Intelligence than the human has many car cameras superior car place, such as not because nap, answer the phone or drunk and accidents, and 360 degrees induction road condition, the response speed faster than humans. Now the global every year 1.2 million people died because of road accidents, if really can like Google in micro bo described in that "our technology can reduce the Numbers, so that even the fallen by half," then the system to give us life brings about change will be revolutionary.
