From January to February 2022, the retail sales of automobiles reached 712.1 billion yuan, an increase of 3.9% year-on-year, indicating that automobiles are one of the pillar industries of the national economy. On March 18, Yan Jianlai, Secretary-General of the Society of Automotive Engineers of China, Chai Zhanxiang, Assistant President of the Automotive Industry Branch of the China Council for the Promotion of International Trade, and Changan Automotive Engineers gathered in the online live broadcast room of the People's Network to talk about the new trends of automobile consumption, and to professionally and systematically interpret the aspects of automobile safety, power, intelligence, NVH, and reliability, aiming to provide consumers with a scientific "car selection guide".
Thousands of bumps out of the truth, safety tests are the top priority
For consumers to buy cars, safety is undoubtedly the most important part, and it is also the primary standard for manufacturers to build cars. Before a car goes on the market, it must undergo a rigorous crash test to test the car's ability to protect the driver and occupants in real life in advance and determine whether the vehicle is safe.
At present, the international mainstream safety rating system is the NCAP of the United States, the E-NCAP of Europe, the C-NCAP of China, the J-NCAP of Japan, etc., and the basic idea is to conduct scientific assessment of the vehicle by simulating accidents such as collisions and flips that may occur in the process of reality.
Dian Bo, deputy chief engineer of Changan Automobile's vehicle collision structure development, said that in a crash test, they will cover all accident scenes as much as possible, because in real accident scenarios, the form is often complex and diverse. Not only to do crash tests, but also to carry out a series of work such as the optimization of the vehicle structure and the integration and matching of the constraint system in the preliminary work to ensure vehicle safety.
For example, a car has more than 3,000 solder joints, and Changan engineers will repeatedly simulate and optimize the location, spacing, and form of force during the collision. In order to ensure a 100% pass rate, Changan Automobile will pass the non-optimization, testing, verification, and improvement at any cost until it is perfect.
From standing up to running, Changan Automobile's independent brand has risen strongly
From following to leading, the rapid rise of mainland independent brands is obvious to all, and the production and sales of mainland automobiles in 2021 were 26.082 million and 26.275 million units, ranking first in the world for 12 consecutive years; the added value of automobile manufacturing from January to December increased by 5.5% year-on-year. According to data from the Ministry of Industry and Information Technology, chinese brand passenger car sales in 2021 were 9.543 million units, up 23.15% year-on-year. While sales are rising, the quality of national brand cars has also been recognized by consumers, and considering buying a car of its own brand has become a trend for more young people.
In the field of research and development, national brands have also shown the strength to wrench wrists with well-known foreign brands. From January to February 2022, the cumulative sales of the "Blue Whale Family" series of models exceeded 190,000 units, leading the independent brand. The reason why Changan Automobile Blue Whale Power can be in a leading position, The chief power division Wang Xiangang pointed out that Changan engineers will continue to use the knowledge and skills of multiple disciplines to systematically and comprehensively analyze in the development process, create every detail and use scenario, and provide users with excellent power products and the ultimate driving experience, which is changan's original intention and the direction of Changan's continuous efforts to move forward.
Changan Automobile has established a complete test and verification system from hardware to software: from chip selection, hardware design, battery compatibility, in-car video and 4G, 5G networking, and then to software code development, Changan Automobile has independently established a series of automated test systems and test equipment to ensure that the car can be fully tested and verified before delivery to the user, ensuring the quality of delivery.
With the upgrading of automobile consumption, users pay more and more attention to intelligence and comfort
Under the background of intelligence and networking, the technology research and development strength of the mainland automobile industry has been continuously improved, which has promoted the upgrading of automobile consumption quality, and also shown new vitality and new atmosphere. Yan Jianlai, secretary general of the Society of Automotive Engineers of China, particularly stressed that comfort is an important consideration indicator for consumers when choosing a car.
Yu Xiongying, senior engineer of Changan Automobile NVH, took noise as an example to introduce how to make drivers and occupants have a comfortable and pleasant experience, he pointed out that the development of automobile NVH is to control the noise and vibration of the car, there are three levels. The first level is abnormal noise cancellation to ensure that the user drives without interference; the second level is low noise control to ensure the user's comfortable driving experience. The third level is the sound quality design to enhance the user's driving pleasure. At present, Chang'an is very mature at the first level, and the focus is on development at the second and third levels.
In addition, Changan Automobile adheres to innovative technology to lead development, and invests 5% of its sales revenue in research and development every year, and has invested more than 123.5 billion yuan so far in the "Eleventh Five-Year Plan". At the same time, during the "14th Five-Year Plan" period, Changan Automobile plans to invest an overall investment of 150 billion yuan, Changan Automobile has a total of more than 6,000 patents, of which Changan Automobile has mastered more than 200 intelligent core technologies, such as IACC adaptive endurance, APA5.0 automatic parking, WeChat car version and other leading technologies in the mass production of its products, bringing consumers a more convenient car experience.
It is worth mentioning that Changan Automobile is carrying out the "Integrity Carpooling Festival" activity in March, during which the purchase of Changan Automobile can enjoy a cash discount of up to 16,000 yuan, and immediately enjoy 24 periods/36 periods/48 periods of zero/low interest and a maximum of 8,000 yuan of replacement subsidies, this preferential policy will continue throughout March.
Write at the end:
In the 2021 evaluation results of the National Enterprise Technology Center, Changan Automobile Group won the first place in the automotive industry with an excellent score of 97.1 points, once again showing its technical strength to the public. From the research and development, manufacturing and listing process of Changan Automobile, we have seen the power of the upward development of Chinese brands. At present, the strength and confidence of domestic brands make the purchase of domestic products a fashion, young people's recognition of national brands has gradually improved, and the development of Chinese brands is booming!
