ABS (잠김 방지 브레이크 시스템) is a safety feature in vehicles designed to prevent the wheels from locking up during hard braking. This system allows the driver to maintain steering control while braking, which is crucial in emergency situations. When the driver applies the brakes, ABS rapidly modulates brake pressure, allowing the wheels to continue rotating. This helps to reduce stopping distances on slippery surfaces, such as wet or icy roads, enhancing overall vehicle stability and safety.
