China and Global Automotive High-precision Positioning Research Report 2025: IMU Develops Towards Domain Controller Integration and Software/Hardware Integrated Service Integration' - ResearchAndMarkets.com

The "Automotive High-precision Positioning Research Report, 2025" report has been added to ResearchAndMarkets.com's offering.

IMU develops towards 'domain controller integration' and 'software/hardware integrated service integration'

In 2024, the penetration rate of advanced autonomous driving (L2.5 highway NOA, L2.9 urban+highway NOA) in China's domestic passenger cars reached 11.4%, and this figure is projected to rise to 31.6% by 2030. In highway NOA scenarios, lane-level/decimeter-level positioning is sufficient to identify the vehicle's lane. However, in urban NOA scenarios, due to narrow lanes and complex road conditions, centimeter-level positioning accuracy is required.

As the cornerstone of autonomous driving perception, high-precision positioning holds vast market potential and demands continuous technological advancement.

Future Directions for High-Precision Positioning Development

IMU Integration into Domain Control and Integrated Software/Hardware/Service in End-to-end autonomous driving solution

In end-to-end autonomous driving systems, integrating IMU into domain controllers has become mainstream. With the evolution of autonomous driving, vehicles require higher accuracy and safety in perception and positioning, especially for L3+ autonomous vehicles that demand ultra-high-precision positioning.

In order to help the product application of OEMs, Sixents Technology launched a 'Smart Driving Software, Hardware and Service Integrated Positioning Terminal" in 2024H1. As an organism that is flexibly combined with multiple product lines, the terminal can not only realize the functions of the original P-BOX, but also acts as a priori platform for high-precision positioning domain controller integrated solutions. The high-precision positioning capability has shifted from P-BOX to domain controllers, which requires all product lines to be broken down. This terminal can greatly accelerate the promotion of integrated solutions. In the future, more and more smart driving software, hardware and service integrated positioning solutions will be implemented in various domain controllers.

Sixents Technology's 'Smart Driving Software, Hardware and Service Integrated Positioning Terminal" has a complete closed loop with high-precision positioning capabilities. Its four product baselines - GNSS (satellite navigation), IMU (inertial navigation), PE (terminal algorithm), and CS (differential correction service) have been owned and productized by Sixents Technology after years of R&D and verification. Among them, CS, as the first commercialized product line, has been mass-produced for passenger cars, commercial vehicles, industry applications and other fields. PE has been involved in multiple mass-production projects. Newer GNSS and IMU product lines have been included in mass-production projects.

Sixents Technology's "Smart Driving Software, Hardware and Service Integrated Positioning Terminal" is the first to integrate GNSS+IMU+PE+CS, reducing costs by 30% compared to traditional solutions.

In addition, based on Sixents Technology's globally integrated high-precision positioning services, positioning solutions at home and abroad can be unified, and OEMs do not need to replace software and hardware solutions when going overseas. Sixents Technology's 'Smart Driving Software, Hardware and Service Integrated Positioning Terminal", based on global differentiated services and terminal algorithm groups, can fully cater to a unified architecture in the global market and system-wide localization, forming a stable, safe, and reliable system closed loop.

Sixents Technology has offered over 10 billion times of high-precision positioning services per day, with more than 3,000 sites, more than 15 million designated vehicles of over 40 models.

Multi-sensor fusion positioning achieves SLAM (simultaneous localization and mapping)

The IMU is built into the camera module and uses the visual-inertial navigation system (VINS) to use acceleration data to improve the accuracy and stability of binocular ranging. High-precision vehicle trajectory calculations can be maintained in some extreme environments, such as emergency traffic jams, heavy rain, nighttime, underground parking lots, etc.

Relying on the technological accumulation of UAV systems, DJI began to explore an inertial navigation stereoscopic binocular vision system in the field of intelligent driving as early as 2016. After years of precipitation, the system has matured. In 2025, an inertial navigation trinocular and LiDAR assembly system will be launched, with the cost much lower than the current "LiDAR + vision + P-Box" solution.

In addition to DJI, Sixents Technology has also developed a visual perception positioning terminal that integrates technologies such as binocular cameras, IMU, GNSS, RTK, and visual fusion positioning algorithms.

MEMS IMU chips realize integrated calculation and integrate AI algorithms

STMicroelectronics launched the ASM330LHBG1 automotive-grade AI inertial module to improve vehicle navigation and positioning accuracy and reliability

STMicroelectronics has launched the ASM330LHBG1 automotive-grade inertial module, which integrates a three-axis MEMS accelerometer, a three-axis MEMS gyroscope module and a safety software library. Equipped with ST's machine-learning core (MLC) and programmable finite state machine (FSM), the ASM330LHBG1 can run artificial-intelligence (AI) algorithms in the sensor to provide smart functionality at low power.

Asensing Technology's GST80 programmable MEMS IMU chip with built-in MCU

At the Beijing International Automotive Exhibition in April 2024, Asensing Technology unveiled its new MEMS IMU chip - GST80. This chip is the industry's first programmable automotive sensor with a built-in MCU, featuring high integration, high performance and cost-effectiveness. GST80 is completely independently designed, developed, packaged, tested and produced by Asensing Technology, and the entire production process is conducted domestically, effectively ensuring the security of the supply chain and filling the domestic gap in high-performance automotive-grade MEMS IMU chips.

High-precision positioning from the perspective of OEMs: lower hardware costs and higher algorithm performance

OEMs always seek to reduce costs and increase efficiency. On the one hand, IMU integration is achieved through powerful domain controllers to reduce hardware costs, and SD pro MAP is introduced to replace expensive HD MAP to cut down map costs. On the other hand, the complexity of map algorithms has been greatly improved, such as model-based IMU noise reduction, online calibration and temperature compensation, and the combination of vision, LiDAR and IMU for high-precision map positioning.

As autonomous driving technology continues to mature, more and more vehicles will use laser SLAM and visual SLAM technology to achieve SLAM. The tight coupling of LiDAR, vision and IMU can improve the accuracy, reliability and robustness of positioning and attitude estimation, and is particularly suitable for scenarios with high-speed dynamics, complex environments, many occlusions or unreliable GPS.
