Headlight control device and headlight
First Claim
1. A headlight control device provided in a vehicle to perform headlight control and to control a distribution of light irradiated from a light source, the headlight control device comprising:
- a controller, the controller is configured todetermine, in a determination unit, a presence and an absence of an obstacle in front of the vehicle and determine a position of the obstacle;
set up, in a setting unit, an area covering the obstacle as an intensified illumination area when the determination unit determines the presence of the obstacle, wherein the intensified illumination area is smaller than each of a high beam area and a low beam area and is an area to which the light from the light source is irradiated in a manner different than a peripheral area of the intensified illumination area; and
control, by the controller, the distribution of the light irradiated from the light source so that the intensified illumination area, which is smaller than each of the high beam area and the low beam area and is set up by the setting unit, has an illuminated zone and a non-illuminated zone.

Abstract
A headlight control device provided in a vehicle to perform headlight control and to control a distribution of light irradiated from a light source is provided. The headlight control device includes: a determination unit that determines a presence and an absence of an obstacle in front of the vehicle and determines a position of the obstacle; a setting unit that sets up an area covering the obstacle as an intensified illumination area when the determination unit determines the presence of the obstacle, wherein the intensified illumination area is an area to which the light from the light source is irradiated in a manner different than a peripheral area of the intensified illumination area; and a controller that controls the distribution of the light irradiated from the light source so that the intensified illumination area set up by the setting unit has an illuminated zone and a non-illuminated zone.

14. A headlight control device provided in a vehicle to perform headlight control and to control a distribution of light irradiated from a light source, the headlight control device comprising:
-
a controller, the controller is configured to determine, in a determination unit, a presence and an absence of an obstacle in front of the vehicle and determine a position of the obstacle; set up, in a setting unit, an area covering the obstacle as an intensified illumination area when the determination unit determines the presence of the obstacle, wherein the intensified illumination area is an area to which the light from the light source is irradiated in a manner different than a peripheral area of the intensified illumination area; control, by the controller, the distribution of the light irradiated from the light source so that the intensified illumination area set up by the setting unit, has an illuminated zone and a non-illuminated zone; and specify, in a specifying unit, a classification of the obstacle of which the presence is determined by the determination unit, wherein for every classification specified by the specifying unit, the controller is configured to control the distribution of the light irradiated from the light source in the intensified illumination area.

15. A headlight control device provided in a vehicle to perform headlight control and to control a distribution of light irradiated from a light source, the headlight control device comprising:
-
a controller, the controller is configured to determine, in a determination unit, a presence and an absence of an obstacle in front of the vehicle and determine a position of the obstacle; set up, in a setting unit, an area covering the obstacle as an intensified illumination area when the determination unit determines the presence of the obstacle, wherein the intensified illumination area is an area to which the light from the light source is irradiated in a manner different than a peripheral area of the intensified illumination area; and control, by the controller, the distribution of the light irradiated from the light source so that the intensified illumination area set up by the setting unit, has an illuminated zone and a non-illuminated zone, wherein the headlight comprises a plurality of mirrors to reflect the light irradiated from the light source and to irradiate the reflected light toward the front of the vehicle, each mirror in an ON state reflects the light irradiated from the light source and irradiates the reflected light to the front of the vehicle, and each mirror in an OFF state does not irradiate the light, which is irradiated from the light source, toward the front of the vehicle, and the controller is further configured to control the distribution of the light irradiated from the light source, by individually setting each mirror to the ON state and the OFF state.
