Headlight beam expensive system and a headlight beam expensive method

摘要

A headlight beam expensive system contains a moment position detector, an image pickup device, which is designed for receiving an image of the vehicle of the user is seen to the rear, and for generating image data of the recorded image, a sequence of a vehicle information detecting unit for detecting a result of vehicle information from the image data, a travel past before information unit for predicting a risk of past process, on the basis of a result of vehicle information, a mode switching condition assessment of a unit for judging whether a mode switching condition is satisfied, based on the predicted travel past process, and an automatic position by a unit for switching of a headlamp mode of a high beam mode to a low beam mode, if the mode switching condition is satisfied. If a vehicle past process of a vehicle, which moves behind the vehicle of a user, based on the result of vehicle information, is predicted, the headlight beam mode of the high beam mode is switched into the low beam mode.
