Driving Assistance Area Control for Expressway False Detection

The patent applies dynamics by making the driving assistance area variable rather than fixed. The control device dynamically adjusts the area size based on the vehicle's location (general road vs. expressway). When on general roads, the area is expanded to maximize detection coverage. When on expressways, the area is reduced to minimize false detection of expressway equipment, thus resolving the contradiction between coverage and reliability.

The patent applies local quality by implementing different detection area settings for different locations. Instead of using a uniform detection area, the system adjusts the area size according to the local characteristics of the road type. On expressways, a smaller area is used locally to reduce false positives from equipment like caution lights. On general roads, a larger area is used locally to ensure adequate detection coverage for pedestrians and two-wheel vehicles.
