Infineon and Subaru Partner to Advance Next-Generation ADAS and Vehicle Motion Control

Infineon Technologies AG and Subaru Corporation have announced a collaboration aimed at improving driving safety, confidence, and comfort in future Subaru vehicles. Infineon plays a crucial role in the integrated electronic control unit (ECU) used for Subaru’s next-generation advanced driver assistance systems (ADAS) and vehicle motion control. Compared with earlier generations, Infineon’s latest AURIX microcontroller family significantly enhances real-time processing performance, enabling faster and more reliable handling of vehicle and sensor data.

“As ADAS technologies become increasingly sophisticated, reliable real-time system performance is essential,” said Peter Schaefer, Executive Vice President and Chief Sales Officer for Automotive at Infineon. “Our industry-leading AURIX microcontrollers provide the foundation that enables Subaru to make dependable decisions and control vehicle functions throughout every stage of driving.”

Eiji Shibata, Corporate Executive Officer and Chief Digital Car Officer at Subaru, explained that the company is developing an integrated ECU designed to coordinate its next-generation EyeSight driver assistance system with vehicle motion control for future Subaru models. The AURIX MCU from Infineon serves as the core technology within this integrated controller, enabling powerful sensor fusion and real-time control capabilities that are essential for advancing next-generation ADAS and vehicle dynamics systems.

“Over many years we have built a strong relationship of trust with Infineon,” Shibata said. “Our teams began collaborating from the early stages of development to optimize the design of the AURIX MCU. We value this reliable partnership and look forward to working with Infineon’s future MCU technologies.”

For the new integrated ECU platform, Subaru is implementing Infineon’s most advanced automotive MCU, the AURIX TC4x, to increase computing power and improve in-vehicle networking capabilities. The TC4x will function as the primary controller for next-generation ADAS features managed by the ECU. It performs real-time sensor fusion and processes inputs from cameras, radar, and other sensing systems to enable faster and more dependable driver-assistance responses.

The TC4x architecture integrates up to six processor cores running at 500 MHz, allowing synchronized operation while supporting automotive functional safety levels up to ASIL-D. This high level of performance helps deliver robust real-time control and decision-making for advanced driving applications.

Infineon and Subaru have already collaborated on Subaru’s current-generation ADAS platform. Looking ahead, both companies intend to deepen their cooperation in areas such as vehicle computing and networking technologies, further driving innovation and value creation to support safer and more reliable mobility.

One year ago, Infineon became the global leader in the microcontroller market after already securing the top position in automotive MCUs in 2023. The company continues to strengthen its leadership by developing technologies that meet the evolving requirements of automotive manufacturers, including promoting RISC-V as an open standard for automotive MCUs. In August 2025, Infineon also acquired the automotive Ethernet business of Marvell Technology, expanding its MCU-related portfolio and enabling one of the industry’s most comprehensive centralized computing solutions for software-defined vehicles.
