LONDON--(BUSINESS WIRE)--Technavio analysts forecast the global automotive inertial measurement unit (IMU) sensors market to grow at a CAGR of more than 32% during the forecast period, according to their latest report.
The research study covers the present scenario and growth prospects of the global automotive inertial measurement unit sensors market for 2016-2020. To calculate the market size, the report considered a combination of top-down and bottom-up approaches, wherein our in-house databases have been used to arrive at the automotive IMU sensors market.
Technavio automotive analysts segment the global automotive inertial measurement unit sensors market into supply side drivers and demand side drivers. Some of the major drivers impacting the market are discussed below:
- Advances in IMU manufacturing technologies to increase their salability
- Extensive research for low-cost IMUs in self-driving cars to drive IMU adoption
- Government regulations on passenger safety
- Increased adoption of automotive safety systems by carmakers
Advances in IMU manufacturing technologies to increase their salability: a supply side driver
Vendors such as InvenSense and STMicroelectronics have developed dies that can integrate both accelerometers and gyroscopes into closer packing sizes. Packaged combo sizes of sensors are now available at 10x10 mm² size, which is further expected to decrease with reducing die sizes. Now, IMUs are enhanced with sensor-fusion software in the application features such as automatic screen rotation, gesture recognition, step-counting, personal navigation, and free fall detection.
According to Siddharth Jaiswal, a lead analyst at Technavio for research on automotive electronics, “Leading vendors in the IMU sensors market such as STMicroelectronics and Bosch Sensortec have increased their investment in the R&D of sensors. The huge sales potential of this market has motivated vendors to invest more in R&D. They have thus set high standards for every end-product in the sensors space. This increased R&D investment has led to the development of advanced versions of IMUs, efficient gyroscopes, and accelerator. This is expected to drive the market and sustain growth during the forecast period.”
Extensive research for low-cost IMUs in self-driving cars to drive IMU adoption: a supply side driver
IMUs are under limelight due to the ongoing worldwide thrust on autonomous car development. They are used in conjunction with LiDAR and other radar like sensors to provide the navigational intelligence needed for autonomous cars to ply on the road alongside human-driven vehicles. The IMUs provide precise azimuthal measurements that are required by autonomous cars to conduct accurate curvilinear motion. Furthermore, IMUs also provide 6 DOF angular velocity and acceleration data for the car to calculate its own position offline in the absence of GPS signals in areas with low connectivity.
All of these merits a substantial reduction in net manufacturing cost for IMUs. KVH recently unveiled plans for a low-cost IMU equipped with FOGs and GPS. The company claims to meet such cost criteria due to the fact that it controls the entire FOG design and manufacturing process, which allows it enough leeway to cut costs.
Government regulations on passenger safety: a demand-side driver for IMUs
Governments of many countries have realized the importance of ESC systems and are formulating multiple legislations to increase the adoption of such systems. In countries like Sweden, the government uses extensive public awareness campaigns to promote the usage of ESC systems. Currently, Sweden has the highest rate of ESC installation (about 96%). The EU has recently implemented a new safety regulation that makes it mandatory for carmakers to launch all upcoming models fitted with an ESC system. Also, the NHTSA in the US has enacted a regulation that makes an ESC system a standard fitment on all passenger vehicles. In the east, the Chinese government has been known to be quite keen on implementing similar legislations to ensure the safety of its citizens.
Increased adoption of automotive safety systems by carmakers: a demand-side driver for IMUs
Considering the regulatory push discussed above, passenger safety has been a prime concern globally for all carmakers in the recent past. Active safety systems assist in keeping a car under control, thereby preventing vehicle accidents during critical situations and protecting passengers from any injury. Active safety devices are fully automated to help compensate for human error, which is the single biggest cause of most car accidents. These systems help prevent and minimize the effects of a crash. Various active safety systems equipped with ECUs such as antilock braking systems (ABS), engine stability programs, adaptive cruise control, blind spot detection systems, night vision systems, lane departure warning system (LDWS), and intelligent parking assistance systems are being increasingly used in automobiles.
