Recently, the airbag control module (ACU) equipped with a special chip for airbag ignition made in China has completed the assembly of the whole vehicle and sent it to 4S stores.
It is worth noting that the core chips used in this module are CCL1600B, a special chip for airbag ignition independently developed by China Core Technology (stock code: 688262.
SH), and CCFC201xBC series, a master MCU chip.
The airbag ACU scheme of airbag ignition special chip CCL1600B and master MCU chip CCFC201xBC series is adopted.
picture source: national core technology, so far, the key chip product of Chinese automobile industry in the field of passive safety-airbag ignition special chip has entered a new era of loading application, breaking the long-term monopoly of international manufacturers in this field.
Breaking the monopoly, replacing the spring breeze to break the earth, and the airbag, as the core of the automobile occupant auxiliary protection system (SRS), is the last life defense line for drivers and passengers in the event of a collision, and the importance of its safety and reliability is self-evident.
According to the latest statistics of the Ministry of Public Security, by the end of 2023, the number of motor vehicles in China has reached 435 million, including 336 million vehicles and 20.
41 million new energy vehicles.
However, behind these data, there is an alarming phenomenon: in road traffic accidents in China, the death toll caused by every 10,000 motor vehicles is as high as 1.38. In this context, safety is still the primary proposition that can not be avoided in the development of China’s automobile industry.
More and more new energy high-end models use the number of airbags as a selling point, such as Xiaomi SU7’s seven airbags, the M9 with nine airbags, and even some higher-end cars with as many as 24 airbags.
According to the trend, the head Leopard Research Institute predicts that China’s automobile airbag market will grow from 334-66.
8 billion yuan in 2022 to 392.5-78.5 billion yuan in 2025.
The global market will also grow from $15.
01 billion (108.
58 billion yuan) in 2022 to $23.
26 billion (168.
26 billion yuan) in 2030, with a compound annual growth rate of 5.
9 percent over the projected period.
In the automobile airbag market, the special ignition chip, which is the key technology to determine the trigger time of the airbag, is rarely involved by domestic chip companies because of its technical difficulty, high reliability requirements, high development cost and so on.
objectively, it forms a situation in which domestic manufacturers start research and development late, technology hollowing out, and the market has been monopolized by a few chip giants overseas for a long time.
Airbag has become an important part of the neck of China’s automotive electronic chip.
Reflected in the market, Bosch, Continental Group, Italy and France, as well as Elmers and other enterprises carve up the main market share, Bosch exclusive 40%.
Enlarged to the entire ACU module market, it is also highly monopolized by foreign enterprises such as Continental Group, Autoliff, Zaifu, Hella, Bosch and so on.
Therefore, in June 2023, national core science and technology announced that the self-developed airbag ignition drive special chip CCL1600B was successfully tested in Suzhou, indicating that our country has achieved a “zero” breakthrough in this technology field, which has attracted wide attention and affirmation inside and outside the industry.
In December of the same year, China Core Technology and Zhejiang Echuang Technology reached a strategic cooperation to accelerate the large-scale application of domestic chips for airbag controllers.
As the first generation of airbag ignition drive special chip developed based on the high voltage BCD mixed signal platform of China Core Technology, CCL1600B, taking into account the dual needs of vehicle manufacturers for high safety and low cost, integrates the power module, trigger loop module, sensor interface module and complex functional safety design on one chip to minimize the system BOM cost and improve the ability to monitor and deal with abnormal working conditions.
To provide customers with better cost-effective solutions.
CCL1600B combined with independent research and development of the main control chip CCFC201xBC series, China Core Science and Technology successfully constructed a set of “MCU+ASIC” highly compact dual-chip airbag ACU program, which strongly supported the landing of Actronic’s first airbag ACU products, and left a strong ink in the long history of breaking the monopoly of foreign giants on automotive chips in our country.
In recent years, with the rapid expansion of the new energy vehicle market, independent car brands have jumped to 60% of the market share, while China has emerged as the world’s largest automobile exporter.
Behind this magnificent picture, China is gradually building a complete industrial chain system, ranging from infrastructure, key materials, core components to complete vehicles and even brands.
The transformation of automobile electrification and intelligence provides a valuable development opportunity for the domestic automotive chip industry.
Despite the broad prospects, we still have to face many barriers on the rugged journey of localization of high-end chips.
What is gratifying is that a number of local chip enterprises determined to innovate have gone through the baptism of wind and rain, overcome technological difficulties step by step, and gradually began to come to the fore.
National Core Technology is one of the important representative enterprises, and its progress in the field of domestic automotive electronic chips makes people see the hope of the local industry.
After more than ten years of intensive work in the field of automotive electronics, CNS has laid out 12 product lines covering body and gateway control, airbag, powertrain, domain control, new energy power battery management, vehicle networking security, digital-analog mixed signal, DSP for active noise reduction, on-line chassis, instrumentation, auxiliary driving and intelligent sensing.
In order to further strengthen the professional “moat” and form differentiated core competitiveness, the company has greatly increased its R & D investment in the past two years, reaching 152 million yuan in 2022 and 178 million yuan in the first three quarters of 2023, respectively.
The year-on-year growth rate reached 70.
11% and 99.
24% respectively, mainly used for the intensive research and polishing of automotive electronic chips, aiming to lead the industry in the future with scientific and technological innovation.
Years of research and development accumulation, so that core technology has a solid technical reserves, and thus successfully into a number of Tier1 suppliers and vehicle supply chain, with BYD, Chery, SAIC, Changan, Geely, Guangzhou Automobile, Dongfeng, Xiaopeng and other more than a dozen automotive mainframe factories have close cooperative relations.
Focusing on the field of airbag chips, CCL1600B is not the first attempt of China Core Technology in the field of automotive airbag control.
As early as the first half of 2022, its 32-bit gauge MCU CCFC2012BC, which was independently designed based on the PowerPC instruction set, has been fully domestically produced in the aspects of core IP, design, package testing, etc.
Now it has been widely used in key scenarios of automotive electronics, such as body control, vehicle control, gateway system and airbag control system.
With its excellent reliability and safety, CCFC2012BC, as the main control chip, has successfully enabled the safe launch of 2 million airbags, laying a solid foundation for the independent research and development of China Core Automotive chips.
From ice-breaking “independent intellectual property high-performance embedded CPU” technology, to bravely breaking the blue ocean of automotive chips, to now successfully developing the first domestic airbag ignition special chip, each leap is the crystallization of team wisdom and sweat.
Video source: national core technology, a high-tech enterprise born in Suzhou hot land, constantly pursues the perfect combination of performance and technology with its soul of outstanding innovation.
This insistence on Excelsior coincides with the craftsman spirit handed down from generation to generation of Suzhou embroidery, and also reflects the unswerving commitment of national core science and technology to technological innovation and quality improvement.
At the end of the message, in the process of the reform and evolution of the “New four modernizations”, the automobile industry in the past hundred years is experiencing the largest industrial chain and value chain reconstruction in history, and a new qualifying race has officially begun.
As National Core Technology stressed, “for domestic chip research and development, has been working hard to move forward”, only through independent innovation to master the core technology, we can climb the peak of the industry, and then lead to become a strong engine driving the giant wheel of the times.
China is already the largest automobile market in the world, and we believe that the local core enterprises represented by National Core Technology will further empower the digital transformation and development of automobile enterprises while breaking the monopoly of foreign capital and filling the gaps in the domestic industry.
in this complementary development, local chips will achieve a real rise and provide solid support for the dream of a powerful country in China’s automobile industry.
