Many cars in Tesla and Lexus have "assisted driving technology" that is not new, but L4-class self-driving cars that do not need people to drive at all, that is, more unmanned vehicles exist in news reports before, many people are I only heard the sound of it. Yesterday, on the eve of the World Internet Conference, the Wuxiang scenic spot in Tongxiang, Zhejiang Province, Baidu unmanned vehicles opened the veil and welcomed the first passengers including me. I am also fortunate to be the 26th passenger to experience Baidu's unmanned vehicles. Since this is the world's first unmanned car public experience event, I think I should be the 26th unmanned passenger in the world, which makes me feel that I have made a special trip. Wuzhen is worthwhile, and the future of Baidu's unmanned vehicles has become more clear than ever.
The Baidu Unmanned Vehicles Division was established at the end of last year, but Baidu’s research and development on unmanned vehicles has been a long time. Previously, it cooperated with BMW. Based on the BMW 3 Series car development, the unmanned vehicles were tested on the Beijing Fifth Ring Expressway. Successful, the top speed reaches 100 km / h. The unmanned car I experienced in Wuzhen this time is a newly developed product of Baidu.
Different from the previous highway road test, this time Baidu unmanned vehicle is driving on urban roads. There are many social vehicles, pedestrians, electric vehicles and even grandfathers on the road. It is much more difficult than the highway. More importantly, this is not a one-time road test, but a continuous and continuous VIP experience from around the world to participate in the Internet World Congress. This experience has a "quasi-commercial value" rather than a laboratory product compared to a single high-speed road test.
Baidu has divided the two models for everyone to experience. One is to cooperate with BYD, and the other is to cooperate with Chery. They are all pure electric vehicles. The reason for choosing these two products is to consider the consideration of supporting domestic cars. As can be seen from the license plates, these cars are exclusively transported from Beijing to Zhejiang by Baidu.
From the appearance point of view, there is no difference between an unmanned car and an ordinary car. The most prominent difference is the top radar. When the car is running, the 64-line laser radar will rotate at a high speed, and the outer body has left, right and rear directions. The 16-line laser radar forms a "1+3" architecture with 360° no dead angle scanning pavement.
After sitting on an unmanned vehicle, you can experience the refinement of the radar on the car tablet. The unmanned vehicle has a built-in high-precision map, and the map has a very accurate route, which is refined to the ground whether it is a solid line or a dotted line. Then the unmanned vehicle will draw a dynamic map according to its own displacement situation, combined with the radar scanning data, real-time comprehensive road traffic conditions for optimal decision, and choose the next action, such as the retrograde electric vehicle, if conditions permit Lane change.
Due to the complexity of the road surface, there are citizens, cars, electric vehicles, and animals. According to the regulations of relevant departments, Baidu unmanned vehicles must be equipped with steering wheels, brakes, and security guards. When driving, the safety officer’s hand must “make†the steering wheel. Take over the unmanned vehicle for manual driving in an emergency. In 2016, Baidu launched a number of project cooperation, and signed a cooperation agreement with Wuhu City to build the world's first fully unmanned vehicle operation area; jointly built an unmanned demonstration area with Shanghai International Automobile City for the development of unmanned vehicles. And paving the way for operations. In September 2016, he obtained the California Automated Driving Road Test License and completed his first public road test in California in October 2016.
After experiencing it, I feel that Baidu unmanned vehicles are still very "smart". It automatically recognizes traffic lights, left turn, and turn signal lights. This requires real-time and accurate image recognition technology that cannot be achieved by radar. It also completed an overtaking when the front car was slower. At the same time, if the road encounters a retrograde electric car, a pedestrian crossing a road, or even a broken puppy, it can be properly handled. On the same day, Wuzhen weather is not good, there is fog, but Baidu unmanned vehicles can still operate normally, indicating that they have certain adaptability to different weathers, while the traditional aided driving based on image recognition technology relies heavily on the weather, night and It can't work in rainy days, but the weather conditions we face when traveling are complex and changeable, so Baidu's laser-based unmanned vehicles are more adaptable.
Baidu unmanned vehicles have a place that is not as good as people: it looks a bit "stupid" when turning around, it is very curved, just like a novice driver; when taking the brakes, it takes a relatively large movement, and there is a sense of sudden braking. Baidu technicians explained that In the case of sudden safety, the brakes are more radical; the maximum can only be opened to more than 50 yards. Of course, this is related to the speed limit requirement of the urban road traffic department. The previous highway opened to 100 yards. There is also a conservative process in the course of the course, which is to follow the rules, will not rush to change lanes, mainly for safety considerations, which also reflects the biggest advantage of unmanned vehicles: compliance with rules, and most traffic accidents are caused by people or Caused by passive violations.
Baidu unmanned car through the World Internet Conference show musclesBaidu Unmanned Vehicles built the first unmanned experience station in Wuzhen and launched during the World Internet Conference. At the same time, it launched an independent brand “Cloud†for Baidu’s driverless car brain system (taken from “God to Cloud†For the car; oh, meaning a good horse."
In my opinion, this is a Baidu unmanned vehicle that wants to show its muscles to the world. After all, the World Internet Conference itself has become a window for Chinese Internet and the world to communicate. During the Wuzhen Internet Conference this year, CCTV “Focus Interview†and other programs were also featured on Baidu unmanned vehicles with independent intellectual property rights. It can be seen that the state is still very supportive of this kind of independent innovation. In fact, last year, Wuzhen Internet Conference had visited Baidu unmanned vehicles and gave affirmation.
Like the Dajiang UAV, Baidu unmanned vehicles have become a representative force created by China, which caters to the “innovation†trend that China is pushing. That is to say, Baidu unmanned vehicles have a rare policy opportunity. Let Baidu unmanned vehicles run faster, and it is more hopeful that China's auto industry will achieve cornering overtaking in the backward background. From Baidu's experience of this choice, support BYD and Chery can also see that Baidu unmanned vehicles are and domestic auto brands. Closely integrated.
Baidu unmanned vehicles will be in the trial commercial stage?Baidu's unmanned car experience is just the beginning. Next, Baidu will conduct experience activities in more cities to let the public understand and accept unmanned vehicles. If you need to experience friends, you can pay attention to Baidu official news. However, in my opinion, the experience of Baidu unmanned vehicles has already had a sense of “quasi-commercializationâ€, or it is the eve of commercialization.
Baidu Unmanned Car Experience Store adopts a “voucher†experience. From the perspective of process design, this method can be directly used in the scenic spot in the future, that is, it can be used as a tourism project to let the tourist groups like teenagers experience the unmanned The magic of the car can also be used as a commute in the scenic area. Because the road is fixed, the road conditions are controllable, and the travel is short, this scene may be the first place for unmanned vehicles to be applied. Baidu chose Wuzhen as the first stop experience, it should be a fancy to the tourism properties of Wuzhen, then Baidu unmanned vehicles may appear in more scenic spots.
I think Baidu unmanned vehicles may also do what Drip is doing. Uber is exploring the unmanned car to show the opportunity of combining unmanned vehicles with shared travel. Now people use mobile phones to look for ofo or motorbikes on the road. After that, they use mobile phones to find or summon unmanned vehicles. Baidu unmanned vehicles may be involved in the unoccupied shared travel market in the future. It seems that this is far away, but the development of unmanned vehicle technology is faster than we think. Who knows how far this is?
Today is the first show of Baidu unmanned vehicles. I am fortunate to be the 26th passenger of Baidu. Although I like the fun of driving, I still expect commercial use of unmanned vehicles. The unmanned vehicles are statistically safer, and based on intelligent dispatching, the overall traffic efficiency can be greatly improved, the congestion problem can be solved and the environment is more environmentally friendly. This is the future. After the experience, I am more certain that this future is no longer far away.
In order to achieve the goal of “three-year mass production, five-year commercialâ€, Baidu is investing heavily in autonomous driving technology. Baidu set up a special autonomous driving department at the end of last year. Bai Jin’s senior vice president Wang Jin is responsible for this business. Baidu also A technical team of more than 100 people was formed in Silicon Valley. At present, the biggest difficulty in the popularization of unmanned vehicles lies in the cost. The 64-line laser radar on the roof is 50-600,000 RMB, which is more expensive than the car itself. However, if the production volume is 1 million units, the radar cost will be reduced to about 500 US dollars. In order to accelerate the maturity and cost reduction of radar technology, Baidu and Ford have jointly invested in the world's leading radar company Velodyne 150 million US dollars, Velodyne said, it is expected 2020 In the year, the price of this equipment will drop to around $300, and in 2025 it will drop to around $200. Now it seems that the popularity of unmanned vehicles is getting closer and closer to us. In the near future, you may be able to brush your friends in the car, watch the live broadcast or enjoy the paper with your sister.
