The Child Presence Detection system uses various sensors to detect the presence of a child or pet in the vehicle and notify and warn the driver. A roadmap for evaluation has been formulated within Euro-NCAP, a European automobile safety testing programme.

Current electronic control units (ECUs) in automobiles use mainly differential signal communications with twisted-pair wires to simplify and reduce the weight of vehicle wiring harnesses.
Among these, the CAN (Controller Area Network) communication system is used for communications that require extremely high reliability such as driving, turning, and stopping.

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.
