Publication number: 20060028832Abstract: A control unit of a vehicular headlamp apparatus can selectively perform steering angle control and navigation-cooperative control. The steering angle control operates a drive mechanism based on a steering angle and a speed of a vehicle to control a headlamp's swivel angle. The navigation-cooperative control operates the drive mechanism using a navigation unit to control the swivel angle. When a current position of the vehicle reaches an entry control start point, the control unit starts navigation-cooperative control at the entry into a curved road. The control unit finds a target swivel angle based on a curvature radius and curved road direction information about the curved road. While the vehicle moves from the entry control start point to a curved road start point, the control unit operates the drive mechanism to gradually change the headlamp's swivel angle to the target swivel angle.Type: ApplicationFiled: August 2, 2005Publication date: February 9, 2006Applicant: DENSO CORPORATIONInventors: Yasutoshi Horii, Junichi Hasegawa, Toshio Sugimoto

Patent number: 6626564Abstract: In a headlight optical axis adjusting apparatus and method for a vehicle, the shape of a road in front of the vehicle is detected by a CCD camera based on a change in lane marking line which indicates the lane width on the road, before the steering angle of a vehicle steering wheel is detected by a steering angle sensor. Left and right swivel lights of the vehicle are swiveled and adjusted based on the change in the lane marking line or the steering angle. The optical axis of the left or right swivel light is first swiveled and adjusted based on the change in the lane marking line.

Patent number: 6392364Abstract: A hybrid IC of electronic circuit for a discharge lamp is disposed on the bottom of a metal case. A transformer, an inductor, a transformer, and a capacitor are disposed in a resin case. The resin case is contained in a metal case. In this instance, the transformer, the inductor, the transformer, and the capacitor are located outside the outer periphery of the IC so that the IC does not overlap on the transformer and other components. The transformer for a starter circuit has a secondary winding the inductance of which is 2.5 mH or larger, and a capacitance of a smoothing capacitor of a DC—DC converter is 0.5 &mgr;F or smaller. The switching frequency f of a MOS transistor is selected so that L2×C1 is equal to or larger than 1×10−1×f−1.68.Type: GrantFiled: June 19, 2000Date of Patent: May 21, 2002Assignee: Denso CorporationInventors: Noboru Yamamoto, Yasutoshi Horii, Hiroaki Okuchi, Hiromi Hiramatsu, Kenji Yoneima, Yuji Kajita, Masamichi Ishikawa, Goichi Oda, Tomoyuki Ichikawa, Yukinobu Hiranaka, Yasushi Noyori

Patent number: 6201350Abstract: In a discharge lamp lighting apparatus for a discharge lamp, each circuit component including a starter transformer is assembled to a bus bar casing, and a high voltage terminal of the starter transformer is connected to one end of a connecting terminal. The bus bar casing is adhesive-cemented to a metal base to which a HIC is attached. Then, a sealing resin fills the bus bar casing to seal the starter transformer and the HIC with the sealing resin. After the sealing resin solidifies, the other end of the connecting terminal and an output cable are connected, and subsequently a resin cover is assembled to the metal base. A shielding sheath covering the output cable is fixed to the bus bar casing by a clip. A ground connection part of the bus bar connectable to the ground side of an electric power source is shaped to protrude from the bus bar casing. The cover, the clip, the ground connection part and the base are ground-connected by a thread.Type: GrantFiled: November 1, 1999Date of Patent: March 13, 2001Assignee: Denso CorporationInventors: Hiroaki Okuchi, Hiromi Hiramatsu, Yasutoshi Horii, Noboru Yamamoto

Patent number: 5601354Abstract: An illuminating device for a vehicle head lamp which defines a clear cut line of light distribution pattern. The light from a light source is transmitted through an optical fibre and is incident to a light conducting path lens from the optical fibre in a predetermined pattern defined by a shade. The light conducting path lens condenses and irradiates at an outgoing plane the light from a light incident plane. Thus, light distribution pattern is defined by the shape of the shade and the optical characteristics of the light conducting path lens. An end section of the shade defines an upper cut line, particularly at an opposite lane side, of the light distribution pattern. The shade is provided coincidentally with an optical axis of the outgoing plane of the light conducting path lens.Type: GrantFiled: March 21, 1995Date of Patent: February 11, 1997Assignee: Nippondenso Co., LtdInventors: Yasutoshi Horii, Hideyuki Kato
