20230122166 · 2023-04-20 · ·

A light distribution control device can perform diffused light distribution control designed to widen an irradiation range of a headlamp of an own vehicle. The light distribution control device is equipped with a recognition unit that recognizes a situation around the own vehicle, and a control unit that performs diffused light distribution control when a curve section in front of the own vehicle in a traveling direction thereof is detected, from a result of recognition by the recognition unit. The control unit controls the headlamp such that a non-required irradiation region where irradiation with light is not required is restrained from being irradiated with light and that a region other than the non-required irradiation region is irradiated with more light, when the non-required irradiation region is detected in the irradiation range of the headlamp in performing diffused light distribution control, from the result of recognition.
