  "textContent": "A light distribution control apparatus includes a light distribution control unit (1) that controls the light distribution of a headlamp (HL) by selecting one of a lane mark sensing mode wherein the illumination direction of the headlamp (HL) is controlled based on lane marks (WL) detected by a lane mark detecting unit (2) that detects lane marks (WL) that define an area ahead of a driver's own vehicle (CAR) and a steering angle sensing mode wherein illumination direction of the headlamp (HL) is controlled based on the steering angle of the driver's own vehicle (CAR). The light distribution control unit (1) switches between the lane mark sensing mode and steering angle sensing mode based on at least one of lane mark information about the detected lane marks (WL) and the lane mark recognition rate of the detected lane marks (WL).",
