Radar sensors are faster in response and have longer detection distances than ultrasonic sensors used in R-AEB (Rear Emergency Automatic Braking) devices. Ultrasound is affected by wind or noise, and cameras have drawbacks such as falling functions in dark areas, but radar uses electromagnetic waves that enable stable performance.
Compared to ultrasonic sensors with a detection distance of three meters which reduces the ability to react to moving objects, Hyundai Mobis said ultra-short range radars (USRRs) can detect up to 5 meters. They are cheaper and can be installed inside the bumper of a vehicle.
Hyundai Mobis said it is ready to apply its ultra-short range radar in consultation with carmakers because it has completed performance verification in 12 situations such as near-distance pedestrians, narrow parking spaces and road jaw detection.
The new solution has also met standards set by the European New Car Assessment Programme (Euro NCAP), a car safety performance assessment program, and the U.S. Insurance Institute for Highway Safety (IIHS).
