Hyundai Mobis has unveiled a new rear safety control technology designed to help prevent rear-end collisions, particularly on highways. According to the auto parts manufacturer on Wednesday, the system warns drivers and automatically maintains a safe distance from vehicles approaching too closely from behind.

The technology integrates rear-side radar sensors and front-facing cameras with existing driving control systems. It is activated when a driver uses the vehicle’s smart cruise control system.

If a vehicle is detected following at a dangerously close distance — about 10 meters behind or less — the system issues an audible alert or a visual warning in the instrument cluster.

If the situation continues, the vehicle will automatically accelerate to create a safer buffer. Rear-side radars, located on both sides of the rear bumper, track the tailgater's movement, while the front camera monitors lane position and the vehicle ahead to enable safe acceleration.

This marks a major step forward in what the company describes as “defensive driving” technology — offering protection not only from front-end collisions, but also from rear-end threats.

Some global carmakers currently offer rear-end collision mitigation systems that issue warnings or pre-tighten seatbelts when a crash appears imminent.

However, these systems generally do not allow the vehicle to take autonomous evasive action. Hyundai Mobis’ new technology advances beyond that, enabling automatic speed adjustments to avoid danger without requiring driver intervention, according to the auto parts maker.

The company also revealed ongoing development of additional autonomous safety features, including automatic lane-changing to avoid threats from the rear.

“We will actively protect the safety of mobility users by providing solutions that can respond intelligently not only to front-end risks, but also to dangerous situations caused by rear vehicles while driving,” said Jung Soo-kyung, executive vice president and head of the automotive electronics business unit at Hyundai Mobis.
