As of 2.11, the 2022 Beijing Winter Olympics, Chinese Olympians have won 6 medals! First of all, congratulations to the Chinese Olympians for their excellent results in the Winter Olympics!
But in addition to the Olympic athletes and the ice piers, as an automotive technology media, we are also concerned about other interesting things that are active around the arena, such as autonomous driving, hydrogen fuel, intelligent AI...
Hydrogen fuel vehicles
In the Beijing and Zhangjiakou Winter Olympic Games with a minimum temperature of more than minus 10 degrees Celsius, as a commuting support vehicle serving the Winter Olympics, traditional fuel vehicles that do not conform to the trend of environmental protection were first eliminated, but pure electric vehicles are also extremely challenging here, so hydrogen fuel vehicles are grandly debuted.
The 2022 Beijing Winter Olympics is probably the largest centralized use of hydrogen fuel vehicles at present.
More than 1,000 hydrogen energy models from Toyota, BAIC, Foton, Geely, Yutong and other car companies and other companies serve the Winter Olympics, and there are more than 30 hydrogen refueling stations.
If we are lucky enough to be on the scene, we can probably see Toyota's latest second-generation MIRAI hydrogen fuel cell vehicle, The Costa hydrogen engine hydrogen fuel cell bus, and a series of hydrogen fuel models, including domestic hydrogen energy buses.
Toyota Mirai is a pioneer in roughly counting the entire global hydrogen energy world, the first generation of models debuted in 2014, when the appearance and the fourth generation of Toyota Prius plug-in version is quite similar, but expensive, North American price of 57500 US dollars.
The second generation of MIRAI hydrogen fuel cell vehicles that are now unveiled at the Winter Olympics is based on the GA-L rear-drive platform under the TNGA architecture, with a body size of 4973/1884/1468mm and a wheelbase of 2918mm, which has been transformed into a large and medium-sized new energy luxury model.
Compared with the first generation, the mileage of the second-generation MIRAI hydrogen fuel cell vehicle has increased from the original JC08 working condition of 650km to 850km (WTLP), and the second-generation Mirai also adopts the latest "Toyota Safety Sense" intelligent driving assistance system, focusing on the price compared to the first generation.
Throughout the Winter Olympic Games, 140 second-generation MIRAI hydrogen fuel cell vehicles will be served, in addition, there are 107 Toyota Costa hydrogen engine hydrogen fuel cell minibuses shuttling through it.
Among the domestic manufacturers, Foton Motor has made the largest contribution, providing 515 hydrogen fuel buses for the entire Winter Olympic Games (some equipped with the hydrogen fuel cell system developed by Toyota), which is the absolute main force in the entire winter Olympic hydrogen fuel fleet.
Yutong provided 185 hydrogen fuel buses to serve the whole division of Beijing, Yanqing and Zhangjiakou, including Geely Interstellar also provided 80 hydrogen fuel city buses.
So why hydrogen fuel? Simply put, compared with pure electric vehicles, the advantages of hydrogen fuel are not afraid of low temperatures, the speed of energy replenishment is comparable to that of oil trucks refueling, and it is also very environmentally friendly.
The fuel of hydrogen fuel vehicles is mainly hydrogen and oxidants (pure oxygen or air), a simple chemical formula H2 + O, theoretically the emissions of hydrogen fuel cell vehicles are only pure water.
However, the difficulty of large-scale application of hydrogen fuel vehicles is that the storage and transportation of hydrogen are more complex, and the construction cost of hydrogen refueling stations is much higher than that of gas stations and charging stations.
Moreover, at the moment when electric-based hybrid and pure electric has become the mainstream development trend, it is not realistic for the industry to collectively turn to another new energy route, and only at present, hydrogen fuel vehicles are as good as a thousand, and they can only shine in a small range of special occasions.
Autonomous driving
2022 Winter Olympics, in addition to hydrogen fuel and autonomous driving technology related to cars, the protagonists here are much simpler, mainly two, Mobileye and Toyota.
Mobileye is equipped with mobileye 8 and the Shield+4 AI safety system designed for large urban vehicles on more than 500 buses for athletes, technical officials, media, and more.
Through the Mobileye EyeQ 4H chip, this pure visual solution ADAS system can realize pedestrian and cyclist collision warning, lane departure warning, distance monitoring warning, speed limit warning, front collision warning, focusing on the perception of pedestrians and other vulnerable road groups.
Compared with the EyeQ4 currently equipped with many passenger cars, the EyeQ4H chip supported by the Mobileye 8 Series camera is a significant improvement, that is, the detection and early warning ability of the vulnerable groups on the road, including pedestrians, is stronger in the low-light environment at night, which should be very practical for large commercial vehicles such as buses.
In terms of market prospects, not only vehicles serving the 2022 Beijing Winter Olympics, but also Mobileye's ADAS system is also worth promoting in other regional public transportation vehicles in the future.
The 2022 Beijing Winter Olympics Toyota can be described as very beautiful, not only bringing hydrogen fuel cell fleet but also many other guarantee models, such as e-Palette automatic driving pure electric service vehicle to understand?
During the Tokyo Olympics, e-Palette was used as a shuttle bus in the Olympic Village, and at the Beijing Winter Olympics, e-Palette played a more important role.
With a wheelbase of more than 5 meters and a wheelbase of 4 meters, the e-Palette can accommodate up to 20 passengers inside, and this wide and fat body makes it versatile for logistics, mobile stores, mobile offices and mobile hospitals, and it can even carry a KFC store to you to deliver food.
However, it may only take a little longer to wait, but this self-driving pure electric service vehicle with high-precision maps and sensors such as lidar and high-definition cameras has a maximum speed of only 19 kilometers per hour.
Intelligent AI
In addition to cars, let's talk about something else at the end, the 2022 Winter Olympics can be called the highest technology content of the Current Winter Olympics, all kinds of robots, intelligent AI taking turns, let us see the charm of science and technology again and again, let's briefly say a few.
For example, "AI Coach", students who pay attention to the figure skater Yu Shengyu string probably know what this is.
To be honest, as i was not very concerned about ice and snow sports before, I was also curious when I watched the figure skating competition for the first time, how can the referee's eyes be a ruler, how can I analyze how many points the athletes' actions should be evaluated in a short period of time?
It turns out that all this is not only the referee's strength, but also the credit of ai. The full name of "AI coach" is probably the intelligent ice sports training analysis system.
Through the high-definition camera on the sidelines of the real-time dynamic supervision of athletes, and then the movement target tracking and trajectory visualization, and finally on the monitoring screen to present the skeleton key points and motion trajectory of each athlete, as well as the statistical information of various sports indicators.
AI makes everything obvious, and finally as a coach and referee, how many points to evaluate seems to be clear at a glance...
Similarly, Gu Ailing completed a record-breaking deflection rotation of 1620 degrees for two weeks in the skiing event, and the analysis with the help of AI will also allow even ordinary viewers to see every detail of the action.

Of course, in addition to the application of intelligent AI, there are many intelligent technology applications on 5G, VR, cloud computing, and robots in the entire Winter Olympic Games. Now that the Winter Olympics schedule is also halfway through, the Winter Olympic players will continue to compete on the field, keep an eye on it and continue to cheer and bless them.
