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.

We're bringing together some of the best technologies in the world to make that possible. Following our first autonomous mobility launch in Luxembourg, our next step with NVIDIA and Lucid is to begin a programme in Madrid in 2027. The Region of Madrid is pioneering a structured framework for commercial autonomous mobility in coordination with national authorities. Germany will also be a priority for what comes next, with cities already setting out clear ambitions for autonomous mobility.”

Rishi Dhall, Vice-President of Automotive, NVIDIA, said, “Robotaxis will scale when every vehicle is built on a common, safety-engineered foundation. NVIDIA Hyperion standardises the compute and sensor architecture across vehicle platforms, while NVIDIA Alpamayo Stack and Halos provide the driving intelligence and safety foundation. Bolt’s European platform, operational experience and work with cities and regulators make it a strong partner to bring autonomous ride-hailing to market at scale in Europe.”

HARMAN has received recognition from the AutoTech Breakthrough Awards, marking the fourth consecutive year the company has been honoured by the market intelligence organisation. The Ready Aware platform received the Driver Safety Solution designation for 2026.

Ready Aware operates as a software-defined vehicle-to-network solution that integrates infrastructure feeds, vehicle telemetry, cloud analytics and digital twin data to provide contextual in-vehicle warnings.

The system processes information regarding road conditions, weather, traffic hazards and signal timing to deliver alerts beyond the driver's line of sight. The architecture works with existing 4G and 5G cellular hardware and vehicle cloud environments, enabling automakers to deploy software updates without hardware modifications. The platform supports Euro NCAP compliance requirements and offers over 15 safety use cases, including intersection warnings, red-light notifications and hazard alerts.

Bryan Vaughn, Managing Director, AutoTech Breakthrough, said, “HARMAN Ready Aware is redefining vehicle safety from reactive intervention to proactive awareness. Almost a quarter of U.S. traffic deaths and roughly half of injuries are related to intersections. Cameras and sensors can be limited by physical occlusions and, on their own, may not have access to information about upcoming signal changes or other traffic conditions. Ready Aware’s software-defined model connects the intelligence already present in cities and connected vehicles, then delivers it to the driver as a timely, contextual alert. Ready Aware turns infrastructure data, vehicle telemetry and cloud analytics into actionable driver awareness—available today, scalable tomorrow, and quickly deployable.”

The system uses a cloud analytics and scoring layer named the Confidence Engine to filter data feeds, reduce false alerts and prioritise notifications to minimise distraction. Automakers can integrate the software via client-to-cloud or cloud-to-cloud configurations to support subscription services and feature monetisation.

Suman Sehra, Global Head of Connectivity Product and Portfolio Management, HARMAN, said, “Ready Aware gives automakers a flexible way to move connected vehicle safety from reactive intervention to proactive awareness. By transforming real-time road intelligence into timely, contextual alerts, Ready Aware helps drivers anticipate hazards before they come into view while giving automakers a scalable foundation to continuously enhance safety through software. This recognition reflects HARMAN’s vision for safer, more informed mobility.”
