With the promotion of the three major driving forces of the market, technology and policy, China's sensor industry has ushered in a new opportunity for development. Governments, regulators, and consumers are increasingly demanding safety for driver assistance systems. At the heart of meeting these high security requirements are sensors, electronics and software.

As early as 2019, the US National Highway Traffic Safety Administration under the US Department of Transportation will incorporate Advanced Driver Assistance Systems (ADAS) into the new car safety evaluation star system. In contrast, European safety regulators are scheduled to begin implementation in 2018. This type of vehicle safety evaluation system will promote the rapid development of vehicle safety technology.
This is not just for driving a car safer or easier. Government and consumer goals also include fewer traffic accidents, lower insurance surcharges, and better car fuel economy. The combination of mechanical systems and software and electronic devices has also benefited many automotive component suppliers, especially MEMS sensors, which can be used in large quantities in more limited spaces.
Market research firm IHS Markit expects the market size in this sector to be US$2.8 billion in 2016. From 2015 to 2022, the compound annual growth rate of the MEMS market for automotive applications will reach 6.9%, and will increase to US$3.2 billion in 2022.
In the past few years, MEMS sensors have gained a stable market in mandatory safety systems, such as electronic stability control systems and tire pressure monitoring systems, which have gained popularity in new cars during 2015. Benefiting MEMS suppliers include gyroscopes, pressure sensors, accelerometers, and front and side airbag sensors. In addition, MEMS devices for automotive engine applications are also growing steadily, mainly due to increasing engine management and exhaust gas processing applications. According to the news from Memes, MEMS shipments in these areas will reach 1.34 billion by 2019, compared with 1.08 billion in 2013.
MEMS applications in ADAS
Just look at the annual MEMS and Sensors Executive Congress to get a glimpse of MEMS applications in the ADAS space. For example, at the 2015 conference, Jeff Owens, executive vice president and chief technology officer of Delphi Automotive, shared a car that was equipped with Delphi's ADAS system for 3,400 miles from the Atlantic coast to the Pacific coast. Automated driving experience. The journey lasted 9 days and traveled through 15 states in the United States, using 20 active safety sensors plus GPS, navigation, vision systems and driver condition monitoring systems. Throughout the process, 99% of the journeys were fully automated, generating 3 T of valuable data.
Future vehicles will bring opportunities and challenges to the MEMS industry and supply chain for the inclusion of multiple MEMS devices.
At the 2016 MEMS and Sensor Summit, Jari Honkanen talked about MicroVision's automotive technology that uses head-up display (HUD) to project important information onto the front windshield of a car. With this technology, the driver can see the important information without having to leave the road. Honkanen also demonstrated how MicroVision's laser beam scanning technology, near-infrared lasers and infrared detectors can be applied to MEMS-based scanning LIDAR (Lidar) systems.
The application of MEMS technology allows the scanning LIDAR system to be dynamically changed depending on the application or driving conditions. It has high horizontal and vertical resolution and captures environmental data at low speed, high resolution or high speed and low resolution compared to previous LIDAR systems. Next, this technical concept can also be applied to ADAS applications such as blind spot monitoring and parking assistance systems.
The head-up display system in ADAS applies MEMS technology to help drivers reduce or eliminate distraction and improve safety. It can also be used to display important information and real-time alerts.
When asked about the role that MEMS will play in future cars, Jérémie Bouchaud, director and senior principal analyst at IHS Markit's MEMS and sensors division, predicts that it will be "green, safe and fun." In addition, the car will be powered by electric power and highly dependent on sensors for automatic cruising, he added.
“When components change with the new electrical architecture, electrified vehicles will rely on sensors accordingly. More advanced human-machine interfaces will have virtual reality and noise reduction capabilities supported by head-up display, which will also benefit MEMS manufacturers. Bouchaud explained further.
future
The safety and security needs of automotive applications will not decrease, and the continued pursuit of these applications will continue to drive demand for automotive MEMS sensors. The biggest beneficiaries of automotive MEMS sensor applications will be electronic components, component manufacturers, and of course end users.
The MEMS sensor market in the automotive sector includes not only ADAS, but also electronic stability control, electronic control units, heating and HVAC systems, safety and security, car navigation, camera stabilization systems, in-car microphones, tire pressure monitoring, and automotive engine management systems. , fuel injection system, seat monitoring system, peripheral pressure sensor and oil pressure sensing.
