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.

LG Innotek has expanded its partnership with Zoox to supply camera modules for the serial production of its purpose-built robotaxis. The agreement marks an extension of the multi-year relationship between the two companies as Zoox scales up its autonomous vehicle manufacturing.

It was last year, Zoox opened a serial production facility in Hayward, California, to manufacture its robotaxis and launched a ride-hailing service in Las Vegas.

As per the agreement, LG Innotek will supply high-resolution automotive cameras as part of the robotaxi's sensor suite, which provides 360-degree coverage through overlapping fields of view.

The camera modules feature five fields of view depending on their mounting positions across the vehicle. Built with optical design technology adapted from mobile camera modules, the units are waterproofed to operate under varied environmental conditions. The components are currently being fitted to Zoox robotaxis as part of the vehicle's core perception hardware system.

CarYaar Auto Private Limited, a DPIIT-recognised technology startup, has announced the appointment of Sahaib Singh as its new Co-Founder and Head of Technology. The company, which operates within India’s fragmented car servicing ecosystem, is focused on integrating transparency and digital trust into the automotive aftermarket. Singh’s arrival marks a pivotal moment for the firm as it works to expand its technological infrastructure and formalize a sector traditionally characterised by informal practices.

Bringing over a decade of experience as a full-stack technologist across mobility, freight and artificial intelligence platforms, Singh will now spearhead the company’s technology strategy and product development. His leadership comes at a critical juncture as CarYaar advances its integrated digital platform, which aims to seamlessly connect car owners, workshops and other stakeholders within the automotive service network. The company is prioritising practical solutions over complex enterprise systems, developing a mobile-first, offline-capable and WhatsApp-native interface to ensure accessibility for multi-brand workshops and customers alike.

Under Singh’s technical direction, the platform is being tailored to serve three distinct user groups with specific operational tools. Workshops are equipped with digital job cards, photo-based inspections, parts tracking and billing systems, while service advisors and managers receive web-based applications for estimate creation and analytics. For car owners, the service enables booking, real-time job tracking and digital payments through WhatsApp, eliminating the need for a separate application. The overarching goal is to use technology not merely to digitise existing processes but to fundamentally enhance the relationship between vehicle owners and service providers.

CarYaar’s model emphasises transparency through features such as real-time photo documentation, pre-approved estimates and digital billing, offering customers clear visibility into their vehicle’s service journey. Currently operating with a network of certified empanelled workshops in the Mumbai Metropolitan Region, the startup is actively building a broader technology-enabled ecosystem that includes multi-brand services, roadside assistance and spares management. This strategic expansion reinforces the company’s commitment to developing simple, accessible and genuinely useful technology for the Indian workshop environment.

Joel Daniel D’Souza, Co-Founder & Director, CarYaar Auto Private Limited, said, “Sahaib brings a strong combination of technology depth and experience across mobility and emerging technology platforms. As we scale CarYaar, technology will be central to how we connect customers and workshops, create transparency and bring greater efficiency to the entire ecosystem. His leadership will be critical as we move from building the foundation to scaling the platform.”
