Over the past few days, some citizens in Chongqing and Wuhan have found that there are no drivers or security officers on the taxis they get, but all of them are self driving taxis. It turns out that Chongqing and Wuhan took the lead in releasing the pilot policy on the commercialization of autonomous driving, which allows autonomous vehicles without safety personnel to carry out commercial services on social roads. Unmanned, really coming. Recently, favorable policies on automatic driving have been intensively introduced in many places across the country: on August 1, the first domestic regulation on the management of intelligent connected vehicles, the regulations on the management of intelligent connected vehicles in Shenzhen Special Economic Zone, was officially implemented, which clarified the responsible subjects related to automatic driving; In July, Beijing opened the first pilot of commercialization of unmanned travel service in China, allowing automatic driving vehicles with no safety officer for the driver and safety officer for the passenger to be put into operation... The policy support has been continuously strengthened, showing the confidence and expectation of domestic automatic driving technology. Baidu, Xiaoma Zhixing, Wenyuan Zhixing and other enterprises have realized the commercial operation of autonomous vehicle to different degrees in many cities. To what extent has China's automatic driving technology developed? What is the riding experience of driverless vehicles? Recently, the reporter came to Beijing Yizhuang high-level automatic driving demonstration zone to find out. "More and more like an old driver" the reporter called an autonomous taxi of Xiaoma Zhixing with a mobile phone app. It's raining. Will it affect its performance? The reporter was more curious about this experience. Dodge, accelerate and decelerate, turn left and right, and the vehicle runs smoothly. When encountering a large truck running slowly in front, AI changed lanes to speed up and decisively completed overtaking, with a speed of more than 60 kilometers per hour, slightly lower than the speed limit of this section. "I haven't seen any need to take over for several months. I'm more and more like an old driver." Xiao Zhang, the safety officer in the co pilot's seat, told the reporter. When passing an intersection, the forward direction signal light has turned yellow, and AI chooses to pass at a constant speed without stopping. "It will comprehensively judge the road conditions and its own driving speed to make a decision. Just now, there is no car around, so it can pass safely. This is more in line with the driving habits of human drivers. If you stop, it is a sudden brake, and the passenger experience is not good." Xiao Zhang said. In the rain, not only people's sight will be disturbed, but also the "eyes" of autonomous vehicles will be affected. For auto drive system, sensors including lidar, camera and millimeter radar wave are "eyes". "If water spray cannot be accurately identified and filtered, automatic driving will encounter difficulties, affecting traffic efficiency and driving safety." Zhang Ning, vice president of Xiaoma Zhixing and head of Beijing R & D center, "With the multi-sensor deep fusion technology, the automatic driving sensing system has the ability to detect, classify, track and understand obstacles beyond human beings. It can accurately 'see' the surrounding world in different road conditions, weather and environment. With advanced software algorithms, it can ensure driving safety. Even in extreme weather such as heavy rain, automatic driving vehicles can drive safely." How does the artificial intelligence "old driver" perform at night when it is stable in rainy days? As night fell, the reporter continued to experience. This time, he changed to Baidu's Apollo, another "Star" of automatic driving
