Abstract:
(EN) A headlight control device (21) disposed in a vehicle equipped with a chassis and a body. The body is provided with headlights in which a plurality of beaming devices are arranged, the respective optical axes of the beaming devices being fixed at mutually different angles, and the plurality of beaming devices include a beaming device in which when the body is subjected to a load corresponding to the maximum load capacity, the beaming range is lower than a reference surface, which is an imaginary horizontal surface that is parallel to the chassis and that passes through the headlights. A body angle estimation unit (41) estimates the body angle, which is the angle between the chassis and the body. A light distribution controller (44) controls, on the basis of the body angle and the direction of the respective optical axes of each of the beaming devices, the light distribution of each of the plurality of beaming devices so that the beaming range of the headlights is limited to a range extending downwards from the reference surface.
(FR) La présente invention concerne un dispositif de commande de phare (21) disposé dans un véhicule équipé d'un châssis et d'un corps. Le corps est pourvu de phares dans lesquels une pluralité de dispositifs de formation de faisceau sont agencés, les axes optiques respectifs des dispositifs de formation de faisceau étant fixés à des angles mutuellement différents, et la pluralité de dispositifs de formation de faisceau comprennent un dispositif de formation de faisceau dans lequel, lorsque le corps est soumis à une charge correspondant à la capacité de charge maximale, la plage de formation de faisceau est inférieure à une surface de référence, qui est une surface horizontale imaginaire qui est parallèle au châssis et qui passe à travers les phares. Une unité d'estimation d'angle de corps (41) estime l'angle de corps, qui est l'angle entre le châssis et le corps. Un dispositif de commande de diffusion de lumière (44) commande, sur la base de l'angle de corps et de la direction des axes optiques respectifs de chacun des dispositifs de formation de faisceau, la diffusion de lumière de chacun de la pluralité de dispositifs de formation de faisceau de telle sorte que la plage de faisceaux des phares est limitée à une plage s'étendant vers le bas à partir de la surface de référence.
(JA) 前照灯制御装置(21)は、車台と車体とを備え、各々の光軸が相互に異なる角度で固定されている複数の照射器が配列される前照灯が車体に設けられ、車体に最大積載量の荷重がかかった際にも照射範囲が、前照灯を通る車台と平行な仮想の水平面である基準面よりも下方になる照射器が複数の照射器に含まれている車両に配置される。車体角度推定部(41)は、車台と車体とのなす角である車体角度を推定する。配光制御部(44)は、車体角度と複数の照射器の各々の光軸の方向とに基づき、前照灯の照射範囲が基準面以下の範囲に限定されるように、複数の照射器の各々の配光を制御する。
