China's science and technology have risen in an all-round way, and one scientific and technological innovation after another has inspired Chinese people and shown the world the great strength of China's intellectual creation.
In recent years, "scientific and technological innovation" has been repeatedly mentioned and has become a hot word in all walks of life, and the whole country attaches great importance to it.
This is because we suffered a lot here in the past. The warning and lessons of ZTE incident warn us that without our own core technology, no matter how large it is, it will be subject to people. Once stuck, the pillar enterprises will go bankrupt in an instant.
I don't want to be controlled by others, but I can only persist in innovation and achieve technological breakthroughs. In this respect, Changan Automobile is the leader of China automobile industry.
Self-driving cars-the commanding height of competition among big countries in the future
Automobile is the peak of the combination of human life and industry in the era of big industry. In the past 100 years, developed countries in Europe and America competed in the center of the stage. But in the future 100, self-driving cars will be the commanding heights of competition among big countries in the future. In this field, China people will catch up!
At 5 pm on March 10, 2020, Changan Automobile held "Future Technology" in Chongqing. China's first L3 self-driving mass production experience with the theme of "mass production first" was broadcast live on the open road.
According to reports, this activity is the first domestic practice jointly organized by the Chongqing Municipal Government and Changan Automobile under the guidance of the national smart car innovation and development strategy, which further established Chongqing's leading position in the field of smart car application in the country and played a positive role in promoting Chongqing's smart transportation and building a smart city.
▲ On the day of the event, the leaders of Chongqing Liangjiang New District presented Changan Automobile with the certificate of Chongqing Automobile Testing Institute, congratulating Changan Automobile on passing L3 automatic driving system certification.
As can be seen from the live broadcast, Zhu Huarong, president of Changan Automobile, participated in the test ride, and the vehicle with L3-class self-driving was UNI-T which made its debut not long ago. When driving on a structured road with running water, the driver doesn't hold the steering wheel, and when the speed is lower than 40km/h, the driver doesn't even have to look at the road with his eyes. When the rear vehicles change lanes, overtake and get stuck in traffic, self-driving cars can also cope.
According to the draft of the recommended national standard "Classification of Automobile Driving Automation" published by the Ministry of Industry and Information Technology in official website on March 9th, the driving automation is divided into 0~5 levels, among which L3 level automatic driving technology can conditionally realize automatic test drive, which is the watershed between "assisted driving" and "automatic driving".
▲ It is understood that "Automatic Classification of Automobile Driving" is the first national standard for automatic driving classification in China and one of the basic standards of China's intelligent networked automobile standard system, which will provide support for the subsequent introduction of laws, regulations and mandatory standards related to automatic driving in China. The national standard is led by Changan Automobile, which reflects Changan Automobile's outstanding contribution and leading position in intelligent autonomous driving.
The successful holding of the first L3-class self-driving mass production experience in China means that part of driving responsibility is transferred from human to automatic driving system for the first time, which indicates that China automobile industry has entered a new era of automatic driving. For users, L3 autopilot will free users' attention from the congested road conditions and return the wasted time under the congested working conditions to users.
It is understood that the L3 autonomous driving technology exhibited this time is independently developed by Changan Automobile and owns all intellectual property rights for the algorithms of all systems.
▲ Changan Automobile's L3 autopilot technology can take off your feet, hands and eyes for a long time in a specific electronic fence (including typical highways and urban expressways) in traffic jam scenes until the system reminds you to take over. The maximum support speed is 40km/h (the system dynamically adjusts the maximum speed of automatic driving in traffic jams according to the safety risks of the surrounding environment, which can support the maximum speed of 40km/h). If the user is reminded to take over and the user still does not take over, then
Self-driving cars are like a sensitive traveler, with the most sensitive senses, collecting all the information on the road, even every tiny detail.
The L3 autopilot system of Changan Automobile is quite advanced in configuration, and its sensing range covers three 360-degree external environment senses, integrating three sensing systems with different physical characteristics, among which the front-end realizes five-fold sensing redundancy, the maximum detection distance exceeds 200m, and the measurement accuracy can reach 10cm.
Using five millimeter-wave radars, six cameras and 12 ultrasonic radar as the main sensors, we can effectively identify targets and obstacles such as vehicles, pedestrians, cyclists, etc. in the vehicle driving environment, and at the same time, we can sense the driver's vision, fatigue and other conditions, provide reliable basis for intelligent decision-making of the automatic driving system, and at the same time, we can effectively identify lane lines, guardrails, traffic signs and other information. Combining the road information of high-precision map and ADAS map, real-time access to road information within 8 kilometers can achieve high-precision positioning and accurate path planning at the lane level, which can effectively ensure the accuracy of autonomous driving tasks.
Seeing this, some people may have questions. L3 Autopilot is nothing new. Baidu Li Yanhong demonstrated in Beijing as early as 20 17. What is the highlight of Changan Automobile this time?
The highlight is "mass production".
In fact, as early as 20 16, Changan Automobile has basically realized L3-level autonomous driving technology, becoming the first automobile enterprise in China to conduct a long-distance test of 2000km autonomous driving. However, in order to realize L3 autopilot mass production, continuous testing is needed.
The engineer in charge of research and development in the field of autonomous driving told me more than once that it is easy to make a prototype for testing, but you have to really turn it into a car that can be mass-produced. The prototype has only 5% workload.
Automated driving mass production requires not only advanced algorithms, but also stability and consistency. Smart cars delivered to users must be 100% safe and reliable.
It is reported that in the simulation environment, Changan Automobile has done more than 10000 scene tests, more than 200 scene matching and testing on the test vehicle, and finally continued testing on the real road. So far, a total of 50 million kilometers of test mileage has been done, which is equivalent to circling the equator 1250 times.
The reason why Changan Automobile attaches great importance to safety is also closely related to the use conditions of the automobile. Sun and rain, hot and cold summer, long-distance and high-load day and night, low speed for several hours every day! There is no commodity whose conditions of use are more complicated and worse than cars.
In addition, the car is directly related to the safety of users, and its difficulty is completely different from that of TV, mobile phone, air conditioner and computer. If the phone crashes, you can turn it off and restart it. If the car stops suddenly while driving, it may be life.
Therefore, after L3 autopilot technology was implemented on 20 16, Changan Automobile still spent four years doing various tests and verifications to eliminate the uncertain factors one by one.
Now the success of L3 autopilot mass production experience means the arrival of China autopilot era. In the field of intelligence, Changan Automobile has completed the role change from follower to leader.
Why are all the world powers concerned about autonomous driving?
The 5G era is coming!
According to the network simulation experiment conducted by Qualcomm in San Francisco, the average downlink rate of 5G network reaches 1.4Gbps, which is nearly 20 times higher than that of 4G network, while the average delay is reduced from115ms to 4.9ms, and the response speed is nearly 23 times faster.
This is not only an improvement in speed, but also a breakthrough in speed and delay!
When a car drives to 1 80km/h, the delay of1s is 50m. In the high-delay 4G era, you are worried about disconnection when playing a mobile game, but in the low-delay 5G era, cars can drive safely and smoothly, can replace humans, do many things that humans are not good at, and even give birth to new industries.
In the 5G era, autonomous driving will change the entire automobile industry in the future!
Chunjiang plumbing duck prophet, so in recent years, BMW, Ford, Changan and other car companies have announced the transformation from traditional automobile manufacturing enterprises to smart travel technology companies.
In the 5G era, everything is connected, and China, as the country with the largest number of cars in the world, is bound to have the world's largest autonomous driving market as soon as possible under the institutional advantage of concentrating on doing big things. By then, the successful mass production of self-driving cars will surely catch up with traditional automobile powers such as Europe and America.
Therefore, the research and development of autonomous driving is not Chang' an to show off wealth. It is a strategic investment of more intense competition in Chang 'an in the next stage. It is also an important opportunity for Changan to set a new entry threshold for future automobile market competition, and it is also an important opportunity for China people to change the rules of the game in the automobile industry.
And from the national level, this is also a major measure for the country to build a smart city, intelligent transportation and smart car power. From the perspective of scientific and technological innovation, this is a great opportunity for China to become a powerful country in science and technology.
In terms of automobile intelligence, Changan Automobile has a far-reaching layout
Changan automobile has gone through 10 years, making human traffic smarter and safer.
As early as 2009, Changan had realized the importance of autonomous driving technology, and started the overall layout and planning of autonomous driving, and began to form a team to develop autonomous vehicles.
20 1 1 Based on Zhixiang platform, functional prototypes such as pre-collision warning and lane departure warning have been developed.
20 13 developed functional prototypes such as adaptive cruise control and automatic emergency braking based on the escape platform.
20 15 based on CS35 platform, developed a self-driving prototype with the functions of automatic parking, high-speed automatic driving and automatic lane change.
In 20 16, changan automobile became the first automobile enterprise to realize the 2000km unmanned long-distance test;
20 18 changan automobile achievement L2? The domestic mass production of IACC integrated adaptive cruise and APA4.0 automatic parking was started; In 20 19, changan automobile realized the first mass production of APA5.0 automatic remote parking system, realizing one-button remote control and worry-free parking.
Up to now, Changan Automobile has mastered more than 200 intelligent core technologies, and more than 70 intelligent functions are mounted on production models, of which 2 1 is the first in China.
▲ 2065438+In July, 2009, a new generation of L4 autopilot technology appeared in Chongqing Xiantao Big Data Valley, allowing users to get their cars anytime and anywhere. Changan Automobile became the first China automobile enterprise to realize the demonstration operation of L4-class self-driving open public roads.
In the field of autonomous driving, Changan Automobile has successively achieved the "seven firsts" of China brand:
The first to realize the 2000km unmanned long-distance test, the first to realize the mass production of the core technology of automatic driving APA4.0, the first to realize the advanced automatic parking function of APA6.0, the first to realize the mass production of the core technology of automatic driving IACC, the only China automobile enterprise in China to obtain the road test license for smart cars between China and the United States, and the first L4? Public display of autonomous driving (Fuzhou Digital China Summit). L4, the first semi-open park in China? Demonstration operation, providing the last mile travel plan. The first L3 in China? Level-8 automatic driving mass production technology test.
In addition, 20 18? In 2005, 55 Changan cars also set the Guinness World Record honor of the world's first "largest self-driving car parade" and created the legendary history of China brand.
It can be seen that it is no accident that Changan Automobile became the first successful L3 self-driving mass production enterprise in China!
It is also worth mentioning that after the cancellation of the Geneva Motor Show, the product planning of car companies was disrupted. In order to ensure the continuous promotion of strategic layout, major car companies urgently launched live broadcast methods for release. However, the sudden new forms have caused live broadcast websites such as BMW, Mercedes-Benz and Volkswagen to roll over one after another, making them look unskilled under the new marketing model. The China brand, led by Changan Automobile, played the live broadcast easily, presenting a wonderful new product for users in a short time, praising the product strength and the soft power of China brand advertising talents. With the language and pictures that users like to see and hear in the Internet era, the audience can listen to the content of the pain points and subtly convey the highlights of the products.
