German automotive technology giant Continental has developed a new sensor technology that is said to significantly enhance the efficiency and sustainability of electric vehicle (EV) motors.

For the first time, their new e-Motor Rotor Temperature Sensor (eRTS) directly measures the temperature inside permanently excited synchronous motors on the rotor itself.

This innovative approach delivers substantially more precise measurement results than current software-based temperature simulations, drastically reducing the tolerance range from 15deg Celsius to a mere 3deg Celsius. The enhanced accuracy offers a dual benefit for vehicle manufacturers: it enables them to reduce the reliance on costly rare earth elements used to boost magnet heat resistance and simultaneously improve potential motor performance. This, in turn, paves the way for greater sustainability in EV production.

The eRTS is a key development from Continental's E-Mobility Sensors (EMS) product centre, which is dedicated to creating advanced sensor technologies for electric vehicles.

Bin Huo, Head of Passive Safety and Sensorics (PSS) segment, Continental, said, "With less resource consumption and lower costs, eRTS sensor technology is advantageous over current solutions. This innovation shows that investing resources and focusing expertise in our product centre was absolutely the right decision. We will continue to successively expand our EV sensor portfolio."

Higher Measuring Accuracy

The eRTS system comprises two distinct components: a wireless mote temperature sensor unit positioned close to the magnet within the EV motor and a wired transducer element situated outside the motor, connected to the inverter control.

Rotors operate under extreme conditions, with temperatures potentially reaching up to 150deg Celsius. Consequently, precise monitoring and control of heat development in EV motors are paramount. Presently, heat development is not measured directly but is instead calculated based on data from the stator temperature sensor, phase current measurements and environmental variables. This indirect method results in a tolerance range of up to 15deg Celsius. To safeguard magnets from demagnetisation due to excessive heat, expensive rare earth elements are typically used to cover this entire tolerance range and ensure sufficient heat resistance.

The significantly greater measuring accuracy of the eRTS, which reduces the tolerance range to just 3deg Celsius, presents car manufacturers with new design possibilities and freedom in permanent magnet synchronous EV motors.

A considerable proportion of costly rare earth materials, which would otherwise be required to account for the wider tolerance range for safety reasons, can now be saved. Furthermore, the improved accuracy offers the intriguing prospect of enhancing motor performance by pushing the operational limits closer to the actual temperature threshold.

Christoph Busch, Lead – Product Centre, Continental, said, "Our E-Mobility Sensors product centre aims to increase efficiency and sustainability in electric vehicles. The eRTS technology is a prime example of this: reducing the use of rare earths contributes to a more sustainable supply chain, especially given that the number of EVs is expected to greatly increase in the coming years and decades. In combination with other sensor technologies, such as the e-Motor Rotor Position Sensor, it can even act as a system solution to create synergies that can save car manufacturers money and effort."

Ultrasound Technology

The eRTS's two components, the mote element and the transducer element, work in tandem. The mote temperature sensor unit measures the temperature directly at the target area, as close as possible to the magnet. Crucially, the wireless mote draws its energy solely from the wired transducer, which is connected to the Electronic Control Unit (ECU) and simultaneously provides the transducer with its measuring data. The transducer is located outside the EV motor on the chassis and transmits temperature information to the inverter control via a communication interface. Both the mote and transducer communicate using Piezo ultrasound, which also facilitates the energy supply to the mote.

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.”
