Development of accident avoidance technology to supplement ADAS/autonomous driving


When driving, there are often instances where a car, a living thing, or an object appears in front of you and you have to brake suddenly. However, sudden braking does not always lead to accident avoidance.

Shin Sung-geun, a researcher at the Korea Automobile Research Institute's ICT Convergence Research Center, proposed a more advanced accident avoidance technology that protects not only the vehicle itself but also the vehicle behind it in response to the sudden appearance of an object.

Accident avoidance technology, represented by the Autonomous Emergency Braking (AEB) system, is an active safety technology that controls the vehicle independently of the driver for the purpose of accident avoidance. In the West, mandatory installation of AEB is in effect, and it is being legislated in Korea as well.

Active safety systems detect collision risks through the 'perception-judgment-control' process to prevent accidents. Recently, as the automation of automobiles accelerates, the driving subject is changing from the driver to the system. Accordingly, autonomous vehicles require a more advanced accident avoidance system.

The AEB system recognizes the situation ahead using cameras, radars, etc. and prevents accidents by braking just before a collision. This prevents collisions with objects in front, but not with vehicles behind. Level 3 autonomous vehicles tested in California from 2015 to 2017 were involved in more than twice as many rear-end collisions as regular vehicles when AEB was engaged.

Accordingly, researcher Shin Sung-geun developed 'Car accident avoidance technology that considers the risk of collision from all directions.' If the existing AEB system only considered avoiding forward collisions, this technology includes an algorithm that also considers avoiding rear-end collisions. It calculates the deceleration and applies the brakes so that it can stop at a point where it does not hit the front object and the rear vehicle can sufficiently handle it.

It also has an algorithm for the Autonomous Emergency Steering (AES) system. In many cases, the contact area between a pedestrian and a vehicle is not large. Rather than braking, steering can reduce accidents. One thing to consider here is the risk of collision with a side vehicle, and Researcher Shin Sung-geun's technology predicts the location of the collision based on the location of the side vehicle, determines the timing of the steering change, and executes it.

Regarding the automobile accident avoidance technology that takes into account the risk of collision from all directions, researcher Shin Sung-keun emphasized, “It can reduce the risk of rear-end and side collisions that existing advanced driver assistance systems (ADAS) or autonomous vehicles have not taken into account,” and “It can prevent collisions with rear-end vehicles by 75% and reduce accidents by 66% in unavoidable situations.”

This technology is patented. Details can be found at the Technology Information Promotion Agency (TIPA) Technology Exchange Meeting, which will be held online from 1:30 PM on the 14th (Tuesday).
