Seoul, South Korea — June 12, 2025:
Hyundai Mobis has unveiled a new safety technology designed to prevent rear-end collisions on highways by predicting the behavior of tailgating vehicles and responding autonomously. Announced on June 11, the advanced system represents a significant leap forward in rear safety control, integrating sensors and intelligent driving functions to protect occupants from rear-impact risks.
The innovation comes amid increasing concern over rear-end accidents caused by speeding or inattentive drivers approaching from behind. While current technologies in the automotive industry can issue alerts or tighten seatbelts during imminent collisions, Hyundai Mobis' system takes a proactive approach by autonomously adjusting vehicle behavior to prevent an accident before it occurs.
At the heart of the new system are rear-side radars mounted on both sides of the bumper and front-facing cameras. These work in concert when the vehicle is operated under Smart Cruise Control (SCC). If a vehicle behind approaches too closely—within roughly 10 meters—the system emits a warning beep or displays a visual alert on the instrument cluster. If the threat continues, the vehicle automatically accelerates within safe limits to increase the distance from the tailgating vehicle.
The rear radars track the movement of the vehicle behind, while the front camera monitors lane position and the distance to the vehicle ahead. This dual-sensor integration ensures that the acceleration does not compromise safety in front, maintaining stability and control during the maneuver.
What sets Hyundai Mobis' solution apart is its ability to act autonomously, adjusting the car's position without requiring direct driver intervention. This goes beyond the current industry standard, where most systems offer only passive warnings or pre-crash mitigation without actual vehicle control.
In a further step toward enhanced defensive driving, Hyundai Mobis is also developing a lane-changing function that will allow vehicles to shift out of the lane autonomously if a rear threat persists, adding another layer of protective capability.
“We will actively protect the safety of mobility users by providing solutions that can intelligently handle not only front-end safety, but also dangerous situations caused by rear vehicles while driving,” said Jung Soo-kyung, executive vice president and head of Hyundai Mobis' automotive electronics business unit.
The company aims to lead the global market in intelligent safety solutions, as this innovation signals a move toward broader autonomous control over a vehicle’s interaction with its surrounding environment—not just from the front, but also from the rear, where hazards often go unnoticed.
Hyundai Mobis' latest development is expected to enter production in upcoming models and could mark a new standard in rear-end collision prevention technology across the automotive industry.
