The powertrain business area of Continental, Vitesco Technologies, a leading supplier in the field of vehicle electrification, and ROHM Semiconductor, a leading company in SiC power semiconductors, have recently signed a development partnership, beginning in June 2020. Vitesco Technologies will use SiC components to further increase the efficiency of its power electronics for electric vehicles (EV). Through their higher efficiency SiC semiconductors make better use of the electric energy stored in a vehicle battery. Thus, an EV has a longer range, or the battery cost can be reduced without impacting the range.

“Energy efficiency is of paramount importance in an electric vehicle. As the traction battery is the only source of energy in the vehicle, any losses caused by power conversion need to be minimized. We are therefore developing a SiC option within our modular power electronics system," says Thomas Stierle, Executive Vice President of the Electrification Technology business unit at Vitesco Technologies. “To get the maximum efficiency out of the power electronics and the e-motor we will use SiC power devices from our preferred partner. ROHM has convinced us of its products”

“We are looking forward to the future cooperation with Vitesco Technologies”, says Dr. Kazuhide Ino, Corporate Officer, Director of Power Device business unit at ROHM Co.,Ltd “We are the leading company in SiC power semiconductors and have achieved a significant technological lead in this field along with the provision of power solutions combined with gate driver ICs. Together with Vitesco Technologies we want to further improve the energy efficiency of the electronic system in EVs to use the full potential of the SiC technology for a sustainable mobility.”

Squeezing out the best performance level by SiC
Vitesco Technologies is already developing and testing SiC technology in an 800-volt inverter concept to confirm the efficiency potential of the technology. The approach of this program is to look at the complete system of inverter and motor to identify the best combination of device technology and switching strategy.

In this context SiC semiconductors – e.g. SiC MOSFETs for 800-volt battery systems – offer more efficient switching in the inverter (higher frequency, steeper switching slopes) and cause fewer harmonic losses in the electric motor. Also, SiC technology is a key enabler for super-fast charging technology that uses 800 volts.

In the course of the cooperation ROHM and Vitesco Technologies will work on creating the optimum combination of ROHM’s SiC technology for high volume manufacturing and best fit of inverter design for highest efficiency.

“The SiC option is a very promising future part of our modular power electronics system comprising of software, power output stage, and switching strategy”, says Dr. Gerd Rösel, head of Innovation in the Electrification Technology business unit at Vitesco Technologies. “We will work with ROHM on an 800-volt SiC inverter solution as well as on a 400-volt SiC inverter solution.” Vitesco Technology plans the start of production of the first SiC inverter as of 2025, when the demand for SiC solutions is expected to rise significantly. “In other words, our partnership and development are perfectly on time”, says Rösel.

The preferred partnership will also be benefiting from short distances: Vitesco Technologies and ROHM both have sites at Nuremberg (ROHM Semiconductor Group: SiCrystal GmbH), which in turn is not far from Vitesco Technologies’ headquarters at Regensburg.

Hyundai Motor India, in partnership with Radio Mirchi, has launched the Hyundai Traffic Quality Index, a standardised traffic rating framework designed to convey real-time road conditions across seven major Indian cities. The initiative operates across Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, Pune and Kolkata.

The system translates live traffic inputs, on-ground reports and official traffic police advisories into a numerical scale from 1 to 10. The ratings are categorised into three colour-coded tiers: 1 to 3 represented in green for light traffic, 4 to 7 in yellow for moderate traffic and 8 to 10 in red for heavy congestion. Updates are broadcast over Radio Mirchi’s audio network to inform drivers during commutes without requiring direct interaction with mobile devices.

The system processes real-time location data alongside updates regarding road closures, diversions, and civic works. Hyundai Motor India and Radio Mirchi plan to expand the index to additional urban centres in subsequent phases of the project.

Virat Khullar, Head of Marketing, Hyundai Motor India, said, “At Hyundai, our commitment to road safety has always extended beyond the vehicle itself. For over three decades in India, we have continuously invested in technologies and initiatives that make mobility safer and smarter. With the Hyundai Traffic Quality Index, we are taking that commitment a step further by empowering commuters with actionable information. We believe informed and technology enabled decisions lead to safer roads, calmer driving behaviour and better commuting experience. Our vision is for Hyundai Traffic Quality Index to evolve into a daily utility that millions of Indians rely on, much like they check the weather or the Air Quality Index before stepping out.”

Yatish Mehrishi, Chief Executive Officer, ENIL, said, “Radio has always been a trusted companion for people on the move. With the Traffic Quality Index, we are taking that relationship a step further by making traffic information simpler, more consistent and more useful for everyday commuters.

The initiative focuses on the development of a software-defined system-on-chip (SoC) designed for Level 4 autonomous driving applications.

As part of the programme, a team led by Professor Yoshihiro Kawahara at the University of Tokyo is researching physical AI chip design based on specific use cases. Concurrently, TIER IV is developing the logic design for an AI chip aimed at processing inference for end-to-end autonomous driving systems. TIER IV plans to open-source the resulting logic design, compiler, and software toolchain to allow semiconductor manufacturers and developers to modify and build upon the hardware architecture.

The project focuses on developing hardware architectures tailored for Transformer AI models, which process sensor data from cameras and point clouds for perception and motion planning.

The chip design incorporates dedicated circuits for matrix multiplication and attention mechanisms, aiming to reduce power consumption from external memory transfers. To maintain software adaptability, TIER IV is integrating the Tensor Operator Set Architecture (TOSA) as an intermediate representation layer between AI frameworks such as PyTorch and the chip hardware.

The initiative also applies formal verification techniques to mathematically trace numerical consistency during AI model compilation.

Shinpei Kato, Founder and Chief Executive Officer, TIER IV, said, “Advances in AI have been accelerated by powerful computing platforms, including GPUs, which have enabled rapid progress across the industry. As Level 4 autonomous driving moves toward broader deployment, we believe the next step is to complement these platforms with computing architectures designed for real-world and real-time requirements. Through this initiative, we are introducing a software-defined and open approach to AI chip design that combines power efficiency, adaptability, transparency and verifiability. In particular, the ability to understand how an AI model is transformed for execution and to verify the correctness of that processing will be increasingly important as autonomous driving systems are deployed in safety-critical environments. By extending the open-source philosophy behind Autoware from software to AI chip design and related toolchains, we aim to create an open ecosystem in which automakers, semiconductor manufacturers and developers can build upon the technology and continue advancing their own systems. This represents an important step toward a scalable, adaptable and reliable computing foundation for Level 4 autonomous driving.”

Professor Yoshihiro Kawahara stated, “In physical AI applications such as robotics and autonomous driving, GPU power consumption has long been a major bottleneck for deployment on battery-powered devices. This project aims to fundamentally overcome this constraint through a functionally differentiated chip design backward-mapped from specific use cases. I look forward to TIER IV developing chips responsible for high-level decision-making – specifically, the high-level behavioural layer that handles the thinking process essential for end-to-end physical AI and autonomous driving. As the leading force behind Autoware, the global standard open-source software for autonomous driving, TIER IV is democratising design, with an approach spanning application requirements to hardware. This enables applied researchers to shape their ideal semiconductors. This initiative, supported by an open ecosystem, has the potential to lay the foundations for a steady stream of Japanese startups creating high-value semiconductors.”
