The Tokyo, Japan-based group will incorporate Infineon’s AURIX TC4x automotive microcontroller to bolster computing capacity and in-vehicle networking.
Germany’s Infineon Technologies and Subaru have entered a collaboration focused on the design work underpinning Subaru’s future vehicles.
At the centre of the partnership is Subaru’s integrated electronic control unit (ECU) being developed for next-generation advanced driver assistance systems (ADAS) and vehicle motion control.
Tokyo, Japan-based Subaru will incorporate Infineon’s AURIX TC4x automotive microcontroller to bolster computing capacity and in-vehicle networking within the integrated ECU.
The TC4x is planned as the primary controller for the next wave of ADAS functions managed by the ECU.
Infineon said its newest AURIX microcontroller is intended to “enhance” the ECU’s real-time performance versus earlier generations, enabling “faster, more reliable processing of vehicle and sensor information”.
In operation, the MCU is expected to support real-time sensor fusion alongside decision-making and control by drawing on information from cameras, radar and other sensors, with the aim of speeding up and stabilising driver-assistance processing.
The TC4x features up to six 500 MHz cores operating in lockstep and supports automotive functional safety up to ASIL-D.
Subaru said the integrated ECU will coordinate the upcoming generation of EyeSight and vehicle motion control, including all-wheel drive control.
Subaru executive officer and chief digital car officer Eiji Shibata said: “Subaru is working on the development of an integrated electronic control unit that coordinates nextgeneration EyeSight and vehicle motion control for future Subaru vehicles.
“Infineon’s AURIX MCU is a core technology that will support robust sensor data fusion and realtime control within this integrated ECU, and is a key element enabling the evolution of nextgeneration ADAS and vehicle motion control.”
The companies have worked together previously on Subaru’s current-generation ADAS, and said they plan to extend cooperation around in-vehicle computing and networking.
Infineon executive vice president and chief sales officer automotive Peter Schaefer said: “As advanced driver assistance systems become more sophisticated, reliable real-time operation across the entire system is key.
“With our market leading microcontroller family AURIX, we support Subaru in building the foundation needed to deliver dependable decision-making and control across the vehicle.”
Separately, Infineon has recently announced several automotive-related collaborations.
In the past month, it agreed to supply core semiconductors for BMW’s Neue Klasse platform, including the BMW iX3.
In January, Infineon and South Korea-based HL Klemove signed a memorandum of understanding to widen cooperation in software-defined vehicle technologies, combining Infineon’s chip and system-level capabilities with HL Klemove’s background in advanced autonomous driving systems.
Earlier in December, Infineon also expanded work with Lenovo on computing platforms for autonomous driving, targeting advanced driver assistance, energy efficiency and high-speed in-vehicle data exchange.
