Patent number: 11300092Abstract: An ignition coil control device includes: an energization control unit that controls to energize an ignition coil by first energization control and second energization control shorter in energization time than the first energization control; a cruise area determination unit that determines that a driving area of a vehicle is located in a cruise area on the basis of a throttle opening and an engine speed; and an integration counter that is incremented every predetermined time when the first energization control is being executed in the cruise area and is decremented every predetermined time in other cases. When a counter value of the integration counter reaches an upper limit value, a cooling process of switching from the first energization control to the second energization control is executed. Such ignition coil control device can appropriately switch energization time while preventing excessive heating of an ignition coil without using a current sensor.Type: GrantFiled: February 8, 2019Date of Patent: April 12, 2022Assignee: Honda Motor Co., Ltd.Inventors: Toshifumi Osawa, Ryohei Kitamura, Nobuyuki Takenaka, Takahiro Kashima

Patent number: 9688332Abstract: A headlamp assembly for a saddle-type vehicle includes left and right light-emitting portions arranged on left and right sides, respectively, of a housing. Each of the light-emitting portions includes a light source and a concave reflector, disposed proximate the light source for reflecting light forwardly. Each reflector has an inclined surface configured such that the rear surfaces of the reflectors extend in directions separating from each other as the reflectors extend rearwardly. A driver for driving the light sources of the left and right light-emitting portions is arranged behind and in between the left and right reflectors.Type: GrantFiled: March 14, 2014Date of Patent: June 27, 2017Assignee: Honda Motor Co., Ltd.Inventors: Hiroshi Hayashi, Nobuyuki Takenaka, Naoki Murasawa

Patent number: 9676437Abstract: A headlight structure for ensuring easy structural designing of a light guide member to enhance the degree of the freedom of shape. Reflectors and left and right lenses are disposed respectively on the left and right sides of the center of a vehicle body. Second light sources are attached respectively to the left and right of a light guide member which is roughly W-shaped. Attachment portions and connection portions are hidden by a light-blocking light cover. The left and right reflectors and left and right including shining portions that are visible through the lenses wherein light evenness can be enhanced within an externally visible region. The headlight can be easily enlarged in size and in diameter. The second light sources make it is easy to design the structure of the light guide member for enhancing the degree of the freedom of shape.Type: GrantFiled: September 9, 2015Date of Patent: June 13, 2017Assignee: HONDA MOTOR CO., LTD.Inventor: Nobuyuki Takenaka
