Cameras, Light Detection and Ranging (LiDAR), and radar can’t see around corners. And, they cannot see emergency vehicles that are far away but fast approaching. The best line-of-sight sensors in the world are limited by the fact that they can’t see threats that are hidden from view. With the addition of obstructed view scenarios into the safety standards of Euro NCAP and other international testing bodies, finding new ways to detect threats is critical.

The Reality AI solution uniquely combines both hardware and software to give passengers a new level of protection.

Automotive Safety Warning System (SWS)  Detects and Localizes:

  • Emergency vehicles
  • Cars
  • Trucks
  • Motorcycles
  • Bicycles
  • Joggers

Reality AI SWS from Renesas: Cars Can See with Sound

ADAS systems today mostly rely on computer vision techniques to detect targets. But, blind corners and obstructed view situations are a real problem. Working with our partners, Renesas has used a mic array on the exterior of the vehicle to HEAR the presence of emergency vehicles, cars, motorbikes, bicycles, and even pedestrians - then LOCALIZE them to inform the driver where to look to see them coming.
