Title:
CONTROL DEVICE FOR VEHICLE HEADLIGHT, CONTROL METHOD FOR VEHICLE HEADLIGHT, AND VEHICLE HEADLIGHT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/095633
Kind Code:
A1
Abstract:
The present invention improves the lighting effects of a low beam while suppressing dazzle during ADB control. A control device for a vehicle headlight according to the present invention is for controlling the operation of a vehicle headlight and has a variable light distribution ON mode that, when there is an object ahead of a vehicle, sets a reduced light range that corresponds to the position of the object within the irradiation range of a high beam. The control device sets the luminous intensity of a partial range within the irradiation range of a low beam that is a portion of the low beam in the vehicle width direction of the vehicle and goes from a first virtual reference line that is parallel to the vehicle width direction to a prescribed position below the first virtual reference line to a first luminous intensity when the variable light distribution ON mode is set, sets the luminous intensity of the partial range to a second luminous intensity that is higher than the first luminous intensity when the variable light distribution ON mode is not set, generates a control signal for operating the vehicle headlight on the basis of setting results for the reduced light range and setting results for the luminous intensity of the specific range, and outputs the control signal to the vehicle headlight.
