Adaptive cruise control is an advanced driver assistance system that automatically adjusts a vehicle's speed to maintain a safe distance from the car in front. Unlike traditional cruise control, which maintains a constant speed, adaptive cruise control uses sensors to monitor traffic conditions and can slow down or speed up as needed. This technology enhances driving comfort and safety, especially on long trips or in heavy traffic. By reducing the need for constant speed adjustments, it allows drivers to focus more on the road while still ensuring a safe driving experience. Features may include radar and camera systems for accurate distance measurement.
