Abstract:
PURPOSE: A curved road active warning system and a warning method using the same are provided to prevent accidents due to speeding on a curved road beforehand by displaying the speed limit and current vehicle speed before entering the curve. CONSTITUTION: A first speed detector detects vehicle speed by being installed at the front of a system. A current speed indicator(200) displays current vehicle speed for a vehicle driver. A plurality of speed limit indicators provides a speed limit to the driver before entering a curved road. A plurality of chevron indicators(400) displays a chevron shape in order to maintain a fixed distance within a curved road section from a rear side separated from the speed limit indicators. A second speed detector(500) detects the average speed of a vehicle passing a section between the neighboring speed limit indicators and the chevron indicator.
