摘要： Beams from headlamps are controlled by a beam control ECU. The beam control ECU has a road-configuration-corresponding mode and a corresponding-turning-angle mode. In the road-configuration-corresponding mode, beam control is performed according to the detected results of a road configuration ahead of a vehicle. In the corresponding-turning-angle mode, beam control is performed according the detected results of the turning angle of the vehicle. One of these modes is selected in response to the vehicle speed. Thus, the beam emitting direction is prevented from being inadvertently changed-irrespective of the rise and fall of vehicle speed-through the actuation of a direction indicator or a steering operation.

摘要： A vehicle lighting apparatus is provided with a travel environment detecting means (2) for acquiring information indicative of a travel environment related to a travel path of a vehicle; a travel region judging means (3) for judging a travel region where the vehicle is presently traveling based upon the information acquired by the travel environment detecting means (2); and a lighting control means (4) for lighting control of a vehicle lighting member (6) in response to a judgement signal derived from the travel region judging means (3). For example, in response to a link number of nodes of a vehicle traveling path, which is obtained from a navigation apparatus (2a) constituting the travel environment detecting means (2), a travel region is judged based upon either a total value of the link numbers or an average value thereof, and an increase/decrease trend thereof. Thus, a travel region where a vehicle is traveling is judged to realize a vehicle lighting control suitable for this travel region.

摘要： Beam control over headlamps is performed with the arriving position, a predetermined time later from the present time, as a target position. At this time, the radius of curvature of a traveling road ahead of a vehicle is calculated on the basis of data from a navigation unit, and the arriving position of one's own vehicle is estimated on the basis of an advisable vehicle speed corresponding to the radius of curvature. Thus, the arriving position of one's own vehicle can accurately be estimated by taking into consideration variation in vehicle speed that is likely to occur in the near future.

摘要： A light distribution control apparatus which is less affected by an error in a navigation function, and conducts a proper light distribution. An illuminated area and a glare quantity are controlled according to a determination on a traveling region of a vehicle (an expressway, a general road, or an urban region), and an illuminating direction is controlled according to a determination on a road shape. On the other hand, a navigation processor determines reliabilities of current position detection, and a vehicle position based on road data, and determines a reliability of the road shape and a reliability of the traveling region. A base illuminated area and a medium glare are selected when the reliability of the traveling region is low, an illuminated area according to the traveling region is selected and the glare quantity is decreased when the reliability is medium, and an illuminated area and a glare quantity according to the traveling region are selected when the reliability is high. A light distribution angle &thgr; hs according to a steering angle is selected when the reliability of the road shape is low, and a light distribution angle &thgr; hn for illuminating a vehicle position after T seconds is selected when the reliability is high.

摘要： An infrared-ray radiating lamp which is prevented from being mistaken for a tail lamp or a stop lamp by ensuring that not only infrared rays but also visible rays are emanated from a front lens simultaneously. The lamp includes a lighting chamber defined by a lamp body and a front lens, a reflector disposed in the lighting chamber, and infrared-ray radiation means and visible-ray radiation means disposed in front of the reflector in the lighting chamber. The infrared rays radiated from the infrared-ray radiation means and the visible rays radiated from the visible-ray radiation means are emanated from the front lens simultaneously when the lamp is lit. Thus, the rays distributed by the lamp include both red infrared rays and white visible rays, and therefore a red color is not particularly noticeable. Thus, the infrared-ray radiating lamp when lit is not mistaken for a tail lamp or a stop lamp.

摘要： A vehicular headlamp includes a projection lens, a light source, a reflector, and a liquid crystal shutter. The liquid crystal shutter includes a pair of transparent plates, a liquid crystal member, and a pair of polarization plates. The liquid crystal member is disposed only in a part of an area between the pair of transparent plates. The pair of polarization plates are disposed only in an area of the outer surface of the pair of transparent plates corresponding to an area in which the liquid crystal member is disposed. The area in which the liquid crystal member is disposed includes a first area for blocking a part of reflected light from the reflector such that light emitted from the projection lens forms a low-beam distribution pattern having a cut-off line at an upper end edge, and a second area for blocking light emitted from the projection lens and then reflected by a road surface ahead of a vehicle toward a space above the cut-off line.

摘要： A headlamp control device is provided. The device includes a visual object luminance unit, an adapted state unit, a recognition limit unit, a visual object recognition unit, and a light distribution control unit. The visual object luminance unit estimates a visual object luminance based on information about a vehicle forward captured image. The adapted state unit estimates an adaptation luminance based on the information about the vehicle forward captured image. The recognition limit unit estimates a recognition limit luminance, in the visual object range, based on at least the adaptation luminance. The visual object recognition unit determines whether the visual object luminance is less than the recognition limit luminance. The light distribution control unit controls a light distribution of a headlamp unit such that the visual object luminance is included in a range of the recognition limit luminance, if the visual object luminance is less than the recognition limit luminance.

摘要： A vehicle lighting system 1 reads position data of a plurality of nodes which are situated ahead of and behind the current position of a cruising vehicle using vehicle current position data and road map data to estimate the shape of a driving path by connecting the plurality of nodes via an interpolation process. Then, as to nodes which are recognized as change points of the shape of the driving path by a road node characteristic position detecting device 4, for example, a bending point or inflecting point, and a starting point and a terminating point of a curve path, a transition range is set ahead of and behind the nodes by a transition range setting device 5. Then, when the cruising vehicle runs through the range so set, a control quantity related to the illumination control of a vehicle headlamp 10 is made to be changed slowly.

摘要： A projection-type headlamp serving also as an infrared light-emitting lamp assuring a sufficient intensity of infrared light irradiation ahead of a vehicle while preventing glare to oncoming vehicles in the adjacent lane. The headlamp is provided with an ellipsoidal reflector, a light source, a shade in the form of an infrared light-transmitting film for reflecting visible light and while allowing infrared light to pass through, and a projection lens for forming simultaneously a predetermined visible light beam pattern and a predetermined infrared light beam pattern, in which an upper edge portion of the shade is positioned above the optical axis of the reflector. A cut line and a hot zone of the visible light beam pattern are set beneath the horizontal line on a light distribution screen so that the visible light beam cannot cause glare for drivers of oncoming vehicles in the opposite lane, and a hot zone of the infrared light beam pattern is set on the horizontal line on the light distribution screen. With this arrangement, the infrared light beam reaches a long distance, and the imaging performance of an infrared noctovision camera is enhanced
