Aumovio’s Remote Temp Sensor Far More Accurate for E-mobility

At the U.S. headquarters for Aumovio SE (formerly Continental Auto Group), the company showed its new remote temperature sensor for EV motors as part of its post-CES tech day presentations. The tech, which provides a more accurate reading of the rotor temperature of an EV motor, could lead to more sustainable motor designs by reducing the amount of rare earth materials used to increase the heat resistance of magnets. It can also improve potential motor performance.

The e-motor rotor temperature sensor (e-RTS) is placed directly near the rotor, improving its tolerance range from 15 degrees C (59 F) to 3 degrees C (37 F). It communicates wirelessly to a wired transceiver elsewhere on the motor module (it can be moved around for better packaging).

Alexander Fink, the company’s head of systems and architecture Americas, said the company believes it is the only wireless sensor currently in the market. He said that until now, temperatures had to be predicted by complicated models. Not having to estimate the temperature, and the resulting reduction of rare earth minerals used also translates to lower cost for motor modules.

He said a motor with the e-RTS would be safer due the ability to control torque more accurately.

The company also has a new rotor position sensor (e-RPS) that measures the angular position of the rotor shaft in synchronous electric motors. Aumovio says it provides amplified analog sine and cosine output signals for the motor inverter.

Autonomy-enabling tech

Aumovio was also showing off its foray into the ultra-powerful compute needed to reach true SAE Level 3 and 4 autonomy. A compact module carrying two NVIDIA Drive Thor SOCs capable of 2,000 TOPS each.

“This is our stack solution,” said Jerry Sumiec, head of high performance computing R&D. “One system could handle Level 3 and two together could get to Level 4.” He said the modules use PCIE 5.0 for data transfer, making them capable of 32 gigatransfers per second (GT/s).

The system has eight GMSL inputs for cameras and can accept up to 22 ethernet ports.

Sumiec said the complete system would be ready by late 2027, but that a developer kit is available now.
