Hyundai Mobis said that it successfully developed the system for detecting rear-seat passengers with a ‘radar’ (ROA, Rear Occupant Alert), and it is planning to propose the system to global automakers.

The ROA is a device for preventing passengers from being left unattended in rear seats. In the past, the weight sensor of children’s car seats or the ultrasonic sensor were used in general. Hyundai Mobis vastly improved detection accuracy by replacing them with the radar sensor. It is expected to greatly help prevent heatstroke accidents caused every summer by children being left unattended in vehicles and other safety accidents.

If a passenger is left in the rear seat, the passenger detection system alerts the driver with the sound made when the door is closed, or through the instrument panel or smartphone. The system, developed by Hyundai Mobis, is known to have secured electromagnetic reliability so that it works normally near high-voltage lines and railroad tracks, and be precise enough to distinguish adults, infants and pets. Hyundai Mobis is planning to develop a radar capable of measuring the heartbeats of passengers and expand the biometric function this year.
