This technology is a vehicle pothole accident prevention support device and its operating method that identifies the presence, location, shape, size, and depth of potholes on the road ahead using 3D scan data from front-facing vehicle sensors, and issues a warning alarm if the predicted driving path, based on vehicle speed and direction, passes over a pothole.
When a vehicle drives over a pothole—caused by water seeping into asphalt and repeatedly freezing and thawing—the vehicle body can tilt suddenly, causing the driver to reflexively jerk the steering wheel, which often leads to rollovers or spin-out accidents. There has been a lack of driver assistance technology that proactively detects potholes, warns the driver, and prevents sudden steering maneuvers while passing over them.
This technology calculates the estimated time of entry into a pothole if the actual driving path does not deviate from the predicted path after an alarm. If the vehicle exceeds a reference speed as it approaches the pothole, it applies resistance to the steering wheel based on speed intervals for the duration required to clear the pothole, thereby suppressing sudden steering. It selects alarm levels based on a risk score adjusted by speed and depth, and provides additional warnings if it detects a drop in tire pressure after passing. Applicable to ADAS in passenger and commercial vehicles and road hazard response modules in autonomous vehicles, it reduces rollovers, spin-outs, and tire damage.
