Driving on a highway often feels threatened by a fast-running vehicle from behind. In addition, there are cases in which a collision accident occurs due to carelessness or drowsy driving of the driver behind the vehicle. In the future, defensive driving that predicts the movement of such a rear vehicle will be possible. Active control technology that uses sensors to approach rear vehicles to escape dangerous situations is expected to be on the market soon.

Hyundai Mobis has developed a rear safety control technology that secures a safety distance on its own after a warning if the vehicle is threatening to drive very close. It is a new technology that links sensors such as the vehicle's rear radar and front camera with driving control technology.

The technology works when a driver is driving on a highway using the Smart Cruise Control (SCC) function. The driver's vehicle recognizes it as a sensor when the vehicle behind it travels within about 10 meters of the vehicle, and first transmits a visual warning sign to the sound of a "beep~" or a cluster. If the situation persists after a certain period of time, the vehicle speeds itself up to secure a safe distance. At this time, the rear radar on both sides of the vehicle's rear bumper detects the movement of the vehicle behind it, and the front camera recognizes the lane and the vehicle in front of it to help accelerate safely.




Safety technology considering the rear collision situation is still being mass-produced by some finished car brands. It is a method of warning in case of a rear collision and adjusting the tightening strength of the seat belt in case of an accident. However, these functions are not self-controlled by the vehicle. Hyundai Mobis has increased its technological competitiveness to a level that allows the vehicle to avoid dangerous situations by adjusting the distance between the cars in front and behind.

Hyundai Mobis plans to expand its autonomous control range further for defensive driving of vehicles behind it. Currently, in addition to the acceleration control function that increases the speed of the vehicle itself, it is also developing a function that automatically changes lanes to escape dangerous situations. "We will actively protect the safety of mobility users by providing solutions that can smartly cope with dangerous situations caused by vehicles behind as well as front safety while driving," said Jung Soo-kyung, vice president of Hyundai Mobis' battlefield BU.

Meanwhile, the rear safety control technology developed by Hyundai Mobis is a technology task that won the top prize at the "Hyundai Motor Group Idea Contest" held in 2022. Since then, it has been developed as a technology capable of mass production by starting the main project for about a year. The development period of new technologies could be shortened by utilizing sensors and driving control technologies that are already being mass-produced. Amid growing social interest in defensive driving for rear vehicles, Hyundai Mobis plans to strengthen promotions for domestic and foreign finished vehicles to apply mass production of the technology.
