Sensors for New Mobility
【How electrification and autonomous driving are expanding the role of sensor technologies within automotive designs】

The automotive production landscape is changing. The proliferation of electronic devices and sensors in modern car design has grown exponentially in recent years. It will expand further as the industry continues its transition toward e-mobility and autonomous driving. The core technologies featured in electric vehicles expand the realm into which sensors are deployed. Also, combustion engine vehicle gas sensors have shifted away from exhaust gas monitoring toward internal air quality (IAQ) measurement.
Solution Guides
Sensor Solutions for Thermal Management of BEVs
In electric vehicles (xEVs), thermal management plays a crucial role for battery safety and longevity, inverter and motor monitoring, and comfort also. For this purpose, TDK offers a broad variety of innovative NTC and PTC based temperature sensors solutions, optimized by their design and specification for the respective applications. However, advanced Micronas Hall sensors and motor controllers also perform important tasks, for example in the high-precision control of valves.

    • TDK Product Features
    TDK offers both TMR sensors and Hall-effect sensors for angle measurements. TMR angle sensors are high-output, high-accuracy, and high-stability sensors that apply TMR (Tunnel Magneto Resistance) technology, which has shown excellent results in HDD heads, in a small package. Particular Hall-effect sensors, so-called direct-angle sensors, make use the 3D HAL technology featuring additional vertical Hall plates to enable the measurement of magnetic field components in the chip plane. These sensors provide an output signal, which is proportional to the angle and position information.
