ADAS, the advanced driving assistance system, also known as the active safety system, uses the on-board sensors to collect the internal and external environmental data at the first time, and performs technical processing such as static and dynamic object recognition, detection and tracking, so that the driver can get the fastest time. An active safety technique that detects possible hazards and draws attention to improve safety.
The ADAS system mainly includes the following functional modules: body electronic stability system ESC (ESP), adaptive cruise system ACC, lane offset warning system LDW, lane keeping system LKA, forward collision warning system FCW, automatic emergency braking system AEB, traffic signs Identify TSR, blind spot detection BSD, night vision system NV, automatic parking system APS, tire pressure monitoring system (TPMS), etc.
Due to the increasing safety standards of automobiles, the level of automotive electronics, and the growing demand for driving safety, the ADAS system with active safety technology has shown a rapid development trend in recent years. According to US market research firm strategy analysis company data, the automotive electrical components market is expected to grow rapidly from $239 billion in 2015 to $303.3 billion in 2020. Among the global automotive electrical components market, the ADAS (Automated Driver Assistance System) chip business is the fastest growing, with an average growth rate of 13% expected in 2015-2020.
In 2015, the Chinese market suddenly emerged as a number of independent brands of ADAS providers. Its representatives include Suzhou Zhihua, Shenzhen Qiangqiu, Shanghai Longituo Technology, Beijing Zhongke Huiyan, Nanjing Chuanglai Technology, etc., making the foreign mobileye ADAS The price of the product has dropped from 17,000 yuan to 9,000 yuan, and the mid-level car within 200,000 yuan has begun to show a rich ADAS configuration. We saw a rich ADAS configuration on the self-owned brand passenger cars produced by Geely, Changan and Guangzhou Automobile in 2015.
Geely Borui's 2015 1.8T flagship is equipped with ACC (Adaptive Cruise Control), SVC (Panorama Camera), LDW (Drive Departure Warning System), BSD (Parallel Assist System), FCW (Forward Collision Warning System or Active Brake) 6) ADAS functions such as system) and AP (automatic parking in place), the average price of each ADAS function is 3,000 yuan.
China is the world's largest automobile production and consumption country. In 2015, China's automobile market has reached 170 million vehicles (including 125 million private cars), and will grow rapidly in the future with an annual growth rate of nearly 20 million vehicles. The Chinese auto market accounts for more than 30% of global auto sales, but the ADAS share is significantly lower than 30%. With the upgrading of consumption structure and the increase in demand for middle-class car purchases, the demand for ADAS will explode in the future.
The analysts expect China's ADAS market to grow at a compound annual growth rate of 35% from 2015 to 2020. In 2020, China can achieve nearly 80 billion yuan in market space.

National policies promote the rapid development of ADAS
ADAS technology can be applied not only to luxury cars, but partly because of competition considerations, but not the only factor, and government regulations are also an important factor.
Based on the dominant advantages of ADAS loading, the policy has forced the ADAS penetration rate to increase significantly. 90% of faults during driving are caused by driver's operational errors, and ADAS active safety can significantly reduce the frequency of accidents. The “automotive safety market†has become the direction of policy efforts of national policy makers.
The European market has made corresponding regulations for ACC, ESC (ESP), LDW, LKA, and AEB in ADAS. In 2014, the weight of the ADAS score was adjusted from 10% to 20%. In 2017, any one who wants to rate 4 stars or more New cars must be equipped with an active safety system. At the same time, for the new car after 2011 and the vehicles registered after 2014, the ESC (ESP) system is mandatory. With the EU's policy of drastic policy for the ADAS system in the front-loading and after-loading markets, the penetration rate of the main functional modules of the EU market in 2017 will be Will reach more than 90%.
The United States, Canada, Japan, and Australia have also imposed mandatory regulations on ESCs (ESPs), while Japan and Australia require each vehicle to be equipped with an AEB system.
In China's newly announced China Car Evaluation Procedure C-NCAP in 2015, it was first clear that ESC (ESP) points can be added by one point to encourage OEMs to manufacture safer cars. C-NCAP is issued every three years. With reference to the policy path of Europe, America, Japan and Canada, we expect that there will be more new regulations for AEB and other ADAS in the new regulations in 2018. China's ADAS is expected to usher in 2018 while growing rapidly. A new outbreak.
Interpretation of ADAS Industry Chain
The core of the ADAS hardware is the sensor (camera, radar, etc.) and the processor, while the software core is the algorithm.
Because the chip processor has no hope of localization in the short term, the key to the breakthrough of the domestic ADAS localization is pinned on the algorithm company with independent technology.
The decisive factor for the widespread use of ADAS is cost, which is the advantage of domestic ADAS vendors. At present, domestic ADAS technology is mostly concentrated on the camera + processor. The hardware requirements of the camera are not very high. The monocular ADAS camera can be made in China, so it relies more on software and algorithms. It is a common method used by domestic manufacturers to have a good algorithm and reduce the cost to obtain the market. Of course, the camera + processor can not meet all the functional requirements of ADAS and will be affected by bad weather such as light, fog, dust storms, etc. Domestic manufacturers such as Hangzhou Zhibo and Wuhu Senstek are also developing radar sensors + processors. ADAS products.
At present, there is no single architecture that can meet the needs of various applications. To meet the high performance requirements of ADAS applications, multiple different types of sensors are needed to complete safety-related tasks. This is also the future development direction of ADAS, and is also the domestic ADAS manufacturer. The direction of the effort.
Because the function of ADAS is often bundled through a set of sensors + processors, TIe1 suppliers or system suppliers are the core players in the ADAS industry chain. They are the designers of the solutions, and they are all There are years of accumulation in their respective algorithms.
At present, the ADAS market is mainly monopolized by foreign TIe1 suppliers/system suppliers. In the commercial vehicle market, WABCO, Continental and Bosch have a 60% market share; in the passenger vehicle market, the mainland, Delphi, and electricity Mount, Autoliv and Bosch account for 65% of the market.
Although there are many independent brands of ADAS system providers in China, such as Suzhou Zhihua, Shenzhen Qiangqiu, Shanghai Longituo Technology, Beijing Zhongke Huiyan, Nanjing Chuanglai Technology, etc., and a few products have also entered the pre-installation market test. However, after all, it started late, and ADAS requires a long period of technical accumulation, and it is difficult to compete with foreign ADAS giants in the short term.
Regardless of whether it is the front-loading market or the after-loading market, ADAS is a technology directly related to driving and user safety, and it is a matter of life. Therefore, ADAS is a high-level field. It takes time to accumulate high precision. ADAS manufacturers should abandon the awareness of making quick money.
Mainstream chip vendor solution
Of course, the core role is indispensable to the chip manufacturers, mainly provided by foreign manufacturers. Including Renesas, Texas Instruments, Infineon, XILINX, etc. are playing their respective advantages, launched a variety of ADAS applications.

Domestic development of ADAS industry recommendations:
First, the standard specification should be first
ADAS has not yet adopted the standard of adapting to national conditions in China, and it is still based on international norms. Even if the standard conditions are not mature, it is necessary to first set the product specifications. After all, the ADAS system is related to driving safety products. Standardized management is still necessary. It is more advantageous to regulate the industry as soon as possible. At the same time, domestic authorities also need to determine the authoritative testing organization to conduct standardized testing of products.
Second, improve the recognition accuracy of ADAS
Identifying accuracy is the core competency of ADAS, depending on the software and hardware. In terms of software, the core is the algorithm. ADAS is a high-level field, not to say how difficult it is to enter this field, but rather to make the function of ADAS accurate. The core of ADAS is the danger warning. It is relatively easy to achieve the accuracy of the warning by 90%. The real difficulty is to increase the 90% to 99.9% or even 99.99%. It is necessary to do this. A large number of actual road tests are used as the data base, combined with the continuous polishing of the accuracy and robustness of the algorithm. Established in 1999, Israel's ADAS company Mobileye has accumulated data for 10 years and continued to invest for 10 years. The recognition accuracy of a complete ADAS system is 99.99%. It can be seen that this is an accumulating process.
Third, the ADAS program should consider the combination with autonomous driving
Zhao Mingyu, director of automotive electronics solutions at Renesas, said in an interview with Chen Lu, an electronic enthusiast and editor-in-chief recently: "The driverless car is a direction, but it is still far from the Chinese car manufacturer. At this stage, we are more optimistic about ADAS. In 2017, all new models should be equipped with more or less the latest ADAS systems, such as 360-degree look-around systems, lane departure warnings, reversing aids, virtual dashboards, etc."
It is widely recognized in the industry that ADAS will eventually become a part of autonomous driving and even driverless driving. Domestic companies should consider the combination with autonomous driving when developing ADAS solutions. Only by doing so can they be driven automatically or even unmanned in the future. When the times come, they can have a place in the industry.
Xiaobian summary:
With the introduction of the C-NCAP's automatic emergency braking system (AEB) into the new car's five-star rating system and other related car safety policies in 2018, it will promote the rapid development of the domestic ADAS industry, and ADAS is expected to usher in the next year.
