3 ways radar technology is changing the in-cabin sensing market


Radar sensors are not only changing the way that vehicles sense the environment around them, but also how they sense what and who is occupying them. Imagine a car that is capable of detecting a forgotten child in the backseat or a driver with a medical issue and a system designed to take action to mitigate the situation.

Radar’s ability to sense through solid materials makes it possible to detect an unattended child, monitor occupant status and estimate driver vital signs with greater accuracy than ever before.

In this technical article, I’ll explore three trends in the automotive in-cabin sensing market as more automakers shift their attention to radar sensors.

Trend No. 1: Functions beyond child presence detection

In order to comply with regulatory bodies such as the European New Car Assessment Program, automakers are turning to radar sensors to implement child presence detection features. But they’re finding that they don’t have to stop there. 

In this video, you can see how a single radar sensor can detect and determine the position of all occupants inside a car, classify the occupants in rear seats as an adult or a child, and track occupant vital signs.
