Patent number: 9951920Abstract: A vehicle lamp control system is provided which can not only restrict a semiconductor light emitting element from being deteriorated or damaged by sunlight and but also maintain an illumination efficiency of the semiconductor light emitting element. The vehicle lamp control system includes a projection lens, semiconductor light emitting elements disposed near a rear focal point of the projection lens and emit light towards the projection lens, a movable shade which can move between a shading position where the movable shade cuts off light emitted from the semiconductor light emitting elements to be incident on the projection lens and a non-shading position where the movable shade does not cut off light emitting elements to be incident on the projection lens, and a headlamp control unit which executes a control in which the movable shade is moved to the shading position with the semiconductor light emitting elements left switched off.Type: GrantFiled: September 25, 2014Date of Patent: April 24, 2018Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Takeshi Masuda, Michihiko Hayakawa, Takao Muramatsu, Misako Nakazawa, Hidetada Tanaka, Yuichi Shibata

Patent number: 9616750Abstract: A vehicle display system displays information on a road surface. The vehicle display system includes an other-entity detector, an intersection detector, and a display device. The other-entity detector detects whether or not another entity approaches a vehicle mounted with the vehicle display system. The intersection detector detects whether or not the vehicle approaches an intersection. When the other-entity detector detects that said another entity approaches the vehicle or when the intersection detector detects that the vehicle approaches the intersection, the display device displays a predetermined shape in a predetermined region of a road surface ahead of the vehicle while moving the predetermined shape.Type: GrantFiled: August 11, 2015Date of Patent: April 11, 2017Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Yuichi Shibata, Takayuki Yagi, Hidetada Tanaka, Misako Nakazawa, Michihiko Hayakawa, Takeshi Masuda, Toshiaki Tsuda

Patent number: 8552648Abstract: A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes right and left headlamps, and a controller which controls the right and left headlamps. Each of the right and left headlamps is configured to produce a low beam light distribution pattern having a horizontal cutoff line to irradiate a region in front the vehicle headlamp apparatus, and is operable to selectively produce one or both of a right side auxiliary light distribution pattern above a right part of the horizontal cutoff line and a left side auxiliary light distribution pattern above a left part of the horizontal cutoff line. Based on a position of a forward vehicle ahead of the vehicle headlamp apparatus, the controller controls each of the right and left headlamps to produce one or both of the right side auxiliary light distribution pattern and the left side auxiliary light distribution pattern.Type: GrantFiled: June 19, 2009Date of Patent: October 8, 2013Assignee: Koito Manufacturing Co., Ltd.Inventor: Michihiko Hayakawa

Patent number: 8007146Abstract: A vehicle lamp is arranged to switch between a low beam and a high beam. The high beam illuminates a first illumination area, which lies ahead of and square to a center of a vehicle, and a second illumination area, which includes portions lying horizontally further leftwards and right wards and vertically further upwards than the first illumination area. When switching from the low beam to the high beam, the luminous intensity of the second illumination area is increased and thereafter the luminous intensity of the first illumination area is increased. When switching from the high beam to the low beam, the luminance intensity of the first illumination area is decreased and thereafter the luminance intensity of the second illumination area is decreased.Type: GrantFiled: August 28, 2008Date of Patent: August 30, 2011Assignee: Koito Manufacturing Co., Ltd.Inventors: Naohisa Tatara, Kazutami Oishi, Michihiko Hayakawa
