Infineon Technologies (Korea CEO Seung-soo Lee) plays a key role in implementing the Software Defined Vehicle (SDV) architecture through BMW Group's next-generation electric vehicle platform, 'Neue Klasse'.

Infineon announced on the 19th that it supports the implementation of BMW's Neue Klasse SDV through central computing, high-speed data connectivity, and efficient power management and distribution solutions.

This enables the continuous expansion and evolution of vehicle functions, and realizes a safer and smarter mobility environment.

Neue Klasse is BMW Group's next-generation strategic platform that combines electrification, digitalization, and sustainability, based on a flexible and scalable integrated electric-electronic (E/E) architecture.

Neue Klasse’s E/E architecture is based on Infineon’s AURIX™ and TRAVEO™ microcontrollers, BRIGHTLANE™ Ethernet connectivity solutions, OPTIREG™ power management ICs, PROFET™ smart power switches, and eFuse portfolio.

Through a structure that separates software and hardware, it supports Software Over-the-Air (SOTA) updates and enables feature expansion without hardware changes.

Vehicle architecture The key is the 'Superbrains,' which are four high-performance central computing units. Among them, 'Heart of Joy' integrates and controls driving dynamics, such as acceleration, braking, and steering, on a single high-speed computer.

This results in faster processing speeds and minimized latency compared to existing systems, providing a smoother and more immediate driving sensation. Improved driving range is also expected through optimized regenerative braking.

The system is built around Infineon's latest AURIX microcontroller (TC4D) and connects to other systems in real time via BRIGHTLANE high-speed Ethernet.

The remaining three superbrains are responsible for autonomous driving, infotainment, and basic vehicle functions, and the three Zone Control Units (ZCUs) are also implemented based on Infineon MCUs.

The application of the Zone architecture has also significantly simplified the wiring harness structure.

Based on the BMW iX3, wiring length has been reduced by about 600m and weight by about 30%.

In addition, Infineon's PROFET Wire Guard-based smart eFuse replaces up to 150 conventional fuses per vehicle, enabling intelligent power distribution.

This blocks unnecessary power consumption depending on the vehicle condition, and improves energy efficiency by about 20%.

Infineon's strategy is to further strengthen its competitiveness in automotive semiconductors and system solutions in preparation for the SDV era through this collaboration.
