  "textContent": "The invention relates to a light distribution control method and a light distribution control device in which plural illumination regions A1-A8 are arranged in the left-right direction and illuminated by a headlamp in an ADB light distribution pattern PADB, and vehicle positions LP and RP of a vehicle CAR ahead are detected and selected ones of the plural illumination regions A1-A8 are reduced in light quantity according to the detected vehicle positions. In this method and device, corrected vehicle positions aLP and aRP are set that are obtained by adding margins Lm and Rm to the detected vehicle positions LP and RP in the left and right directions, respectively, and compared with the plural illumination regions A1-A8. Illumination regions where the vehicle CAR ahead exists are reduced in light quantity.",
