Automotive technology innovation is inseparable from semiconductors, and semiconductor technology must be at the forefront.
We have noticed that with the development of automotive electronics, automotive intelligent technology is gradually being applied, and future cars will be safer, more environmentally friendly and smarter. The development and integration of sensor sensing, networking, data security, active and passive security, etc., has been the field of exploration for various car manufacturers, component suppliers, and automotive chip manufacturers.
With the electrification and intelligentization trend of automobile development, fuel economy and emission reduction, active safety and autonomous driving, vehicle networking and LED lighting have become the focus of the current automotive industry, which brings more development opportunities to the semiconductor industry. More challenges have also been raised. Hybrid Electric Vehicles (HEVs) / Electric Vehicles (EVs) drive the semiconductor components of each vehicle's automotive powertrain by about five times. Advanced Driver Assistance Systems (ADAS), convenience and infotainment systems, and emerging markets, which account for more than 50% of global automotive sales, drive the global automotive semiconductor market to grow by more than 9% year-on-year.
Semiconductor composition in automobiles
According to data from market research firm Databeans, the average semiconductor product cost per car is $350. The application of semiconductor components in automobiles is shown in Figure 1.

So, in the face of such a huge business opportunity, how do the world-renowned automotive electronic chip manufacturers play the "golden abacus" of cars? High-level original elites from the world's leading automotive electronics chip manufacturers Infineon, Texas Instruments, STMicroelectronics, Analog Devices, ON Semiconductor, Intersil and others gave their views.
Infineon - deep data security and advanced driver assistance systems
Traditionally, a car is a closed system. The realization of the car network makes the car an open system, which makes it easier to upload and download various data and information. However, due to the disclosure of information, it also brings the risk of hacking. .
Senior Director of Infineon Technologies (China) Co., Ltd. and Xu Hui, Head of Automotive Electronics Business in China
Xu Hui, senior director of Infineon Technologies (China) Co., Ltd. and head of automotive electronics business in China, said that the security of the Internet of Vehicles, or data security, is the focus of Infineon.
Xu Hui further pointed out that Infineon is a global leader in automotive electronics and security chips and has accumulated deep technical expertise. Now, ensure that the data communication of connected cars is as safe and secure as possible, laying the foundation for unmanned driving in the future. For example, a microcontroller with a protection mechanism includes a "Secure Hardware Extension (SHE)" and a next-generation "Hardware Security Module (HSM)" basic unit. Many car manufacturers have or will require the use of SHE or HSM in automotive safety protection applications. Infineon has long placed these modules in the standard configuration of the microprocessor. For example, Infineon microcontrollers AudoMax and Aurix contain SHE and HSM respectively, so there is no need to add additional hardware units.
Infineon's M2M chip complies with the AEC-Q100 automotive specification and has been widely used to provide secure data communication on eCall emergency calls and vehicle terminals. The SLI97 V2V series can be used for security control modules based on 802.11p vehicle and car interconnection specifications, OPTIGA TPM It can be used as a security trust anchor in the total gateway of the internal or external data of the vehicle to ensure the security of information communication and access equipment and prevent possible hacker attacks.
In addition to data security, ADAS is another focus area of ​​Infineon's focus.
In fact, Infineon has already started market research and new product development in automotive intelligence. There are four major links in the application of automotive safety technology. From the identification, prediction, prevention and protection, in the first three links, the ADAS system is essential to prevent accidents, improve vehicle safety, and increase driving. Comfort. In recent years, in the advanced assisted driving system ADAS, the adaptive cruise control system (ACC), lane departure warning (LDW) and side object detection (SOD) technologies are currently growing rapidly.
Xu Hui stressed that whether it is a radar or a camera, Infineon can provide a total solution, such as radar system RF sensor, microcontroller and power integration solution, supporting the main automotive radar frequency band and front, rear, side and Various radar systems such as 360-degree viewing; such as 3D camera sensors, microcontrollers and power supply solutions for camera systems, support for front and 360-degree surround cameras to achieve warnings at different distances and angles. With strong integration and innovation capabilities, Infineon supports a wide range of sensor fusion systems to meet the diverse needs of customers.
