The opening of the Beijing Winter Olympics is imminent, and more than 70 "black technologies" will be applied in the event. At the just-concluded Fifth Session of the 13th CPPCC Beijing Municipal Committee, the Winter Olympics of Science and Technology became a hot topic of discussion among CPPCC members. Among them, hydrogen fuel cells and autonomous driving technology will empower the automobile industry and create broad application prospects in future public travel and intelligent transportation.

At Foton Motor's Ouhui Bus Division, the rear of a green-painted bus is emitting pure white gas, water vapor, which is the hydrogen fuel cell vehicle that will be served in the Winter Olympics. This zero-emission bus only needs to be hydrogenated for 10 minutes to run 350 kilometers. Qi Ruzhi, vice president of the Technology Research Institute of Beiqi Foton Ouhui Bus Division, pointed to the 6 hydrogen cylinders under the vehicle and said that they were very safe.
Qi Ruzhi: "There are a lot of sensors in this, monitoring the hydrogen concentration in the cabin, if the limit is reached, it will alarm, and then cut off this valve." The entire bracket structure of the hydrogen cylinder is relatively strong, and last October did the side collision of the first 70 MPa hydrogen fuel cell vehicle in China, specifically hitting this hydrogen cylinder, basically without any damage. ”

Hydrogen fuel cell vehicles are also equipped with batteries similar to pure electric vehicles. The average power battery decays quickly or is difficult to start in the cold, and this car is equipped with an all-climate power battery. Zhou Enfei, head of new energy at the Technology Research Institute of Beiqi Foton Ouhui Bus Division, introduced that it can be started at minus 30 degrees.
Zhou Enfei: "The heating speed of this all-climate battery is very fast, 7 degrees a minute, which means that it is heated from minus 30 degrees to zero degrees, which is also four or five minutes, and it can quickly enter the state of being able to drive." ”

The car is powerful, with a climb of more than 25% and can drive freely in the complex mountains of the Winter Olympics. Half a month later, more than 400 hydrogen fuel cell buses of Beiqi Foton will provide connection services in Yanqing and Zhangjiakou race areas. The reporter learned from many sources that the Beijing Winter Olympics will demonstrate the operation of more than 1,000 hydrogen fuel cell vehicles and more than 30 hydrogen refueling stations. After the Winter Olympics, some vehicles will be used as buses and shuttles to serve ordinary citizens.

Promote the construction of hydrogen fuel cell vehicle demonstration city clusters
At the fifth meeting of the 13th BEIJING Municipal Committee of the Chinese People's Political Consultative Conference this year, Chen Xiaobing, a member of the Municipal Committee of the Chinese People's Political Consultative Conference and deputy editor-in-chief of the Automotive News Department of the Beijing News Agency, introduced that hydrogen fuel cell vehicles are recognized as the ultimate environmental protection path in the industry.
Chen Xiaobing: "Whether it is from the process of hydrogen generation, to the use of fuel cells, and the final result of vehicle emissions, it is zero emissions, which is better than more electrical energy in the current application scenario." The industry expects hydrogen fuel cell vehicles to become popular, and it may take more than a decade. ”

For many years, the high cost was a difficult problem for the development of hydrogen fuel cell vehicles. At present, the cost of fuel cells is 5,000 yuan per kilowatt, and the industry expects that the cost will be reduced to 1,000 yuan per kilowatt before it can be promoted and used on a large scale. In this regard, Sun Ziqiang, member of the Municipal Committee of the Chinese People's Political Consultative Conference and head of the Beijing Eversand Hydrogen Energy Technology Research Institute, believes that first of all, we must continue to make breakthroughs in technology.
Sun Ziqiang: "The 8 card neck technology has basically achieved from scratch, but there is still a certain gap between the quality and cost performance and foreign countries." Like the Japanese Toyota Mirai's stack life is more than 10,000 hours, our domestic good stack life is three or five thousand hours, so how to change these core technologies from 'have' to 'good', this needs to be vigorously solved. ”

In addition, regional synergies for scale are critical. The Beijing Municipal Government Work Report proposes that the construction of hydrogen fuel cell vehicle demonstration city clusters will be promoted this year. Sun Ziqiang, member of the Municipal Committee of the Chinese People's Political Consultative Conference and head of the Beijing Eversender Hydrogen Energy Technology Research Institute, introduced that the three places of Beijing, Tianjin and Hebei have their own advantages.
Sun Ziqiang: "Beijing has the strongest research and development capabilities, the amount of hydrogen used should also be the largest, and the scene is also relatively large; Tianjin has chemical industry, there will be some industrial by-product hydrogen; Hebei has a large amount of wind energy, solar energy, these green energy can support a large amount of green hydrogen, supply to the Beijing-Tianjin-Hebei region." ”

Gao Li, a member of the CppcC Municipal Committee and a professor at the School of Machinery and Vehicles of Beijing Institute of Technology, believes that the hydrogen fuel cell vehicle demonstration city cluster will also drive the high-quality development of the hydrogen energy industry chain and the regional economy.
Gao Li: "From the preparation, storage, on-board and then to electric, not only the traditional machinery industry, but also fuel, chemical, as well as electronic control, electronics, and even non-metallic materials, the industrial ecology and industrial chain should be made longer, larger and stronger." ”
Autonomous driving technology will be publicly demonstrated at the Winter Olympics

In the Yizhuang Economic and Technological Development Zone, a self-driving car travels freely through the traffic flow, starts and stops, merges, turns, and safely completes the 5-kilometer journey in less than ten minutes. Sun Ning, general manager of Beijing Auto Network Technology Development Co., Ltd., the operating platform of the Beijing High-level Autonomous Driving Demonstration Zone, introduced that the operation of the automatic driving system completely relies on the car to collect information.
Sun Ning: "After the car itself collects perception information, including the cars next to it, the brother who delivers the courier, and the pedestrians, traffic lights and other various information collections, the car to make decisions and implementation, there is no need for manual participation." ”

There are always blind spots in the perception of vehicles, such as unexpected situations such as ghost probes, and extreme weather such as rain, snow and fog, which will make self-driving cars unable to see the surrounding road conditions. At this time, the smart car must cooperate with the smart road. Sun Ning pointed to the square facility on the pole body of the smart intersection and said that it was called a roadside communication unit.
Sun Ning: "The roadside communication unit synchronizes the roadside perception information to the car within 150 milliseconds, so that the vehicle can make decisions, the accuracy error of the obstacle can be within 0.5 meters, and the accuracy rate at the lane level reaches more than 99%, so as to achieve safer automatic driving." In terms of intelligent transportation, through the combination of signal machines and signal lights, the efficiency of the trunk road of Rongjing Street and Ronghua Road can be improved by 30%. ”

In the Beijing High-level Autonomous Driving Demonstration Zone, the data of all autonomous vehicles and smart roads are summarized on the cloud control platform, which can supervise and dispatch vehicles, and can also complete the definition of 17 types of traffic events such as retrograde, construction occupation, and vehicle failure on the basis of big data. Sun Ning, general manager of Beijing Auto Network Technology Development Co., Ltd., the operating platform of Beijing High-level Autonomous Driving Demonstration Zone, said that in the future, ordinary private cars can receive traffic incident prompts released by the cloud control platform as long as they install on-board communication units.
Sun Ning: "As long as you enter the Yizhuang area, you can clearly get the traffic light status of the intersection in front of you, how many seconds are left to go straight, and how many seconds are left to turn left." For example, if you have a bus in front of you, you can know if you want to follow the bus directly to the intersection. For example, if the road ahead is under construction, or if there is a faulty car parked, it can be broadcast to the traditional production car, and you can avoid the obstacles in advance and plan your own route. ”

During the Beijing Winter Olympics, such autonomous driving technology will be publicly demonstrated near Shougang Park. Last year, Beijing took the lead in building a high-level autonomous driving demonstration zone in the country, covering an area of 225 square kilometers in Yizhuang, Beijing.
Carry out the construction of high-level autonomous driving demonstration area 3.0
The government work report proposes that the construction of a high-level autonomous driving demonstration zone 3.0 will be carried out this year, that is, scale deployment and scene expansion. Wang Xianjin, member of the Municipal Committee of the Chinese People's Political Consultative Conference, vice president and chief engineer of the Scientific Research Institute of the Ministry of Transport, believes that high-level automatic driving is good for traffic safety.
Wang Xianjin: "Through smart cars, smart roads and the platform system behind them, we can solve the intrinsic security of dreams." If our algorithms and computing power reach a certain level, they should be able to exceed the ability of people to operate. ”

Yang Wenliang, member of the Municipal Committee of the Chinese People's Political Consultative Conference and general manager of Beijing Yizhuang Investment Holding Co., Ltd., introduced that there are nearly 10 industries and departments in different single facilities on the road, and the construction of intelligent networked roads requires standardization.
Yang Wenliang: "First, can different individuals be unified into a major department for design, construction, operation and management. Second, the government's management has formed a management system with one leading department as the mainstay and other departments as the same. Third, how to break down barriers and form a secure and effective unified sharing of a lot of data across departments also requires a set of standards. ”
Last year, Beijing opened a total of 1,000 kilometers of autonomous driving test roads, with a cumulative test mileage of more than 3 million kilometers. Gao Li, a member of the CPPCC Municipal Committee and a professor at the School of Machinery and Vehicles of Beijing Institute of Technology, believes that in addition to open road testing, simulation and closed site testing should also be strengthened.
Gao Li: "Through the form of simulation, try to encounter more complex scenarios." In an enclosed field, dynamic vehicles that are closer and faster do not pose an actual danger. In this way, we can present extreme, less easily encountered scenes, improve our perception and decision control algorithms, and increase the level of intelligence. ”

At present, autonomous driving is moving from technical verification to business model verification. Xia Shudong, member of the Municipal Committee of the Chinese People's Political Consultative Conference and chairman of Qianfang Technology Group, believes that expanding application scenarios can accelerate industrialization.
Xia Shudong: "Many specific areas such as airports, ports, connections, sanitation, urban management, and self-driving trucks on high speeds can really reduce driver costs." We must find such a scenario with commercial value, give scene support or major project support, and verify its model, and this industry will be formed. ”
