TRAVELING ENVIRONMENT DETECTION DEVICE

摘要

A driving environment detection device acquires a captured image of the direction the host vehicle is travelling in, and from the captured image, extracts parameters relating to brightness of a road surface for a road driven by the host vehicle. Then, on the basis of the parameters, the driving environment of the vehicle is estimated. By way of such a light control system, it is possible to more accurately detect ambient brightness by estimating the driving environment in accordance with the parameters related to the brightness of the road surface. Therefore, it is possible to accurately detect the driving environment.
