Why are more and more business tycoons building cars across borders? This question seems to have no need to be answered, because 5G is coming, and autonomous driving is the new track.
Is it that simple?
In the third issue of China's first popular science program in the field of communications" "Communication Letter" presented by Science and Technology Daily, the World 5G Conference and the Future Mobile Communication Forum, Professor Li Wanlin, director of the 5G and Autonomous Driving Innovation Center of North China University of Technology, cut from the change of 5G technology and automatic driving technology to the traditional automotive industry, and answered many people's concerns about automatic driving.
How has the business logic related to cars changed when various new car-making forces entered the new track of autonomous driving?
Li Wanlin said: "In the past, we told the story of the car, the engine was the key word, it was the threshold for building the car, and it was also the killer skill of the latecomers who were stuck and eager to try. ”
Li Wanlin specifically mentioned a data, traditional cars have tens of thousands of parts, 5G car makers entered, the parts have been reduced by more than ten times. More critically, the century-old car model driven by the engine has ushered in a major change.
Li Wanlin said: "This is equivalent to the threshold being cut thin, so that car building more and more becomes an assembly work, as long as you have money, you have the confidence to enter." ”
So, what will the cars of the future look like?
Li Wanlin's answer was: "Mobile office, mobile hospital, mobile home... The future car woven by each car builder has a different angle of entry, and the scene achieved is more or less the same. ”
"When the automobile industry started a hundred years ago, faced with the choice of two routes of fuel vehicles and electric vehicles, battery technology stuck electric vehicles, and fuel vehicles went on the road." Li Wanlin said, "A hundred years later, the progress of battery technology allows us to regain this topic, and the blessing of 5G, artificial intelligence, cloud computing and other technologies has increased our confidence in promoting cars from fuel to full intelligence." ”
When all kinds of apps carry mushrooming applications to empower smartphones, calling has become the most basic function of mobile phones. In the eyes of new car builders, the car is a big mobile phone, and the value-added space given to the car by this walking APP is not only in the imagination.
Li Wanlin said: "As long as it is a moving object, in principle, it can become a carrier of automatic driving, although the sweeping robot often hits the wall, it also has some automatic driving functions." Autonomous driving is a major functional option for passenger cars, large trucks, logistics vehicles, tractors, robots operating in hazardous locations, and even tanks that will allow machines to fight machines in the future. As a joke, the 'triple jumper' of automatic driving may not be able to drive automatically. ”
Is the technical threshold of this new industry very low?
No, although capital has found a new track, it is not possible to build a good car with money.
Li Wanlin said: "In order to achieve automatic driving, stacking equipment to the car is one of the current paths in the industry, which directly leads to expensive cars. From our calculations, to add the current level of autonomous driving technology to the car of 200,000 yuan, consumers need to pay 500,000 yuan more, which is obviously not an inclusive user scenario. Carry more functions and applications to the cloud server, 'slim down' for the car, and the cost of each car will be reduced a lot. ”
Li Wanlin stressed that unlike mechanically driven cars, many cars now have many processors running, but to achieve the functions of perception, decision-making, and execution of these three automatic driving functions, it is necessary to make collaborative progress in 5G networks, robots, artificial intelligence, video, radar and many other technologies.
"For the driver, God's perspective is the best, omnipresent, we set up cameras, lidar, millimeter wave radar, etc. on the side of the road, all to help self-driving cars perceive the surrounding scene 360 degrees without dead angles and complete the operation through the network." Therefore, vehicle-road collaboration is an important part of the landing of automatic driving technology. ”
So, is the goal of completely liberating human drivers realistic?
"From the perspective of the classification of automatic driving, L0 level is the most traditional car, nothing, L5 level car will be anything, people can sleep in the driving car, but this ideal is still relatively far away." Li Wanlin stressed that at this stage, human drivers are still the protagonists, and automatic driving is more accurately assisted driving, which is a help.
Although the road ahead is long, with the improvement of the network base laid by 5G, all kinds of car manufacturers have entered the market to enhance the rich application of technology, and the development prospects of China's automatic driving are promising.
Li Wanlin said: "China's automatic driving development level is relatively advanced, many technologies are leading, the complexity of road scenes is rare in the world, this high difficulty mode of 'tuning' good cars, there is no place that dare not drive." ”
Automatic driving is to let the car simulate the driver, when the car like a person has a more powerful perception, decision-making, execution capabilities, the safety of the car, the importance of vehicle-road coordination, the rational use and management of data is the key to the future development of the car that Li Wanlin particularly emphasizes.
