- Subaru collaborates with Infineon to develop a high-performance MCU for next-generation ADAS and vehicle motion control.
- The new ECU architecture targets ultra-low latency processing and improved efficiency across electric, hybrid, and gasoline vehicles.
Subaru announced a collaboration with Infineon Technologies to jointly develop a microcontroller for the company’s future integrated electronic control unit platform. The Subaru Infineon AURIX TC4x MCU will support advanced driver assistance systems and coordinated vehicle motion control, forming a key component of the automaker’s next-generation electrical and electronic architecture.
The initiative aims to deliver faster processing performance and improved efficiency as vehicle control systems become increasingly complex across electrified and conventional powertrains.
Next-Generation Integrated ECU Architecture
Subaru is developing a unified E/E architecture designed to serve battery electric vehicles, hybrid models, and gasoline vehicles on a common platform. The integrated ECU will coordinate multiple control domains including driver assistance functions and vehicle dynamics systems.
By consolidating computing capabilities into a centralized architecture, the system is expected to improve responsiveness, streamline system integration, and enable faster communication between critical vehicle functions.
Low Latency and Energy-Efficient Processing
To support increasingly sophisticated driver assistance features, Subaru requires extremely fast processing of vehicle control data while maintaining low power consumption. Achieving both objectives is critical for maintaining efficiency in modern vehicle electronics.
Early Development Collaboration
Subaru participated in early development activities for Infineon’s automotive microcontroller platform to ensure the device meets demanding real-time control requirements. Working closely with the semiconductor supplier allowed engineers to refine hardware specifications and optimize system performance.
Supporting Advanced Driver Assistance and Vehicle Dynamics
The AURIX TC4x microcontroller will power Subaru’s integrated ECU responsible for coordinating next-generation EyeSight driver assistance technologies along with vehicle motion systems such as all-wheel-drive control.
Through the Subaru Infineon AURIX TC4x MCU integration, the company aims to further enhance the core driving attributes it prioritizes—precise acceleration, stable cornering, and reliable braking—while delivering greater confidence and safety for customers.
