A vehicular lighting apparatus comprising: a headlight configured to irradiate the front of a vehicle; a condition detection part configured to detect a weather condition at a position of the vehicle; a travelling route estimation part configured to estimate a road shape of a travelling route in front of the vehicle; a vehicle travelling state detection part configured to detect travelling state of the vehicle; and a control part configured to control a luminous intensity distribution of the headlight, the vehicular lightning apparatus being characterized in that it is configured such that the road shape of a travelling route in front of the vehicle includes the respective road shapes of a travelling route in front of the vehicle corresponding to the vehicle's current and future positions, and when the condition detection part detects such a weather condition as to cause a low visibility in front of the vehicle, the vehicle travelling state detection part detects the vehicle travelling state, the travelling route estimation part estimates the said road shape of a travelling route in front of the vehicle whereby the road shape in front of the vehicle's future position is estimated based on: (a) information in front of the vehicle photographed by a device for photographing the front of the vehicle, (b) information obtained from a route guidance device, and (c) the vehicle travelling state, and the control part controls the luminous intensity distribution of the headlight in such a manner as to irradiate a road surface zone in front of the vehicle with a reduced quantity of light with respect to other areas, the road surface zone in front of the vehicle corresponding to the said road shape of the travelling route in front of the vehicle estimated by the travelling route estimation part. a headlight configured to irradiate the front of a vehicle; a condition detection part configured to detect a weather condition at a position of the vehicle; a travelling route estimation part configured to estimate a road shape of a travelling route in front of the vehicle; a vehicle travelling state detection part configured to detect travelling state of the vehicle; and a control part configured to control a luminous intensity distribution of the headlight, the vehicular lightning apparatus being characterized in that it is configured such that the road shape of a travelling route in front of the vehicle includes the respective road shapes of a travelling route in front of the vehicle corresponding to the vehicle's current and future positions, and when the condition detection part detects such a weather condition as to cause a low visibility in front of the vehicle, the vehicle travelling state detection part detects the vehicle travelling state, the travelling route estimation part estimates the said road shape of a travelling route in front of the vehicle whereby the road shape in front of the vehicle's future position is estimated based on: (a) information in front of the vehicle photographed by a device for photographing the front of the vehicle, (b) information obtained from a route guidance device, and (c) the vehicle travelling state, and the control part controls the luminous intensity distribution of the headlight in such a manner as to irradiate a road surface zone in front of the vehicle with a reduced quantity of light with respect to other areas, the road surface zone in front of the vehicle corresponding to the said road shape of the travelling route in front of the vehicle estimated by the travelling route estimation part. the vehicle travelling state detection part detects the vehicle travelling state, the travelling route estimation part estimates the said road shape of a travelling route in front of the vehicle whereby the road shape in front of the vehicle's future position is estimated based on: (a) information in front of the vehicle photographed by a device for photographing the front of the vehicle, (b) information obtained from a route guidance device, and (c) the vehicle travelling state, and the control part controls the luminous intensity distribution of the headlight in such a manner as to irradiate a road surface zone in front of the vehicle with a reduced quantity of light with respect to other areas, the road surface zone in front of the vehicle corresponding to the said road shape of the travelling route in front of the vehicle estimated by the travelling route estimation part.
