摘要： A vehicle headlight control device includes: an indicator value acquiring unit configured to acquire an indicator value that represents a brightness of an object detected ahead of an own vehicle; a light distribution control unit configured to control a light distribution of a headlight such that a quantity of light irradiated to the irradiation region where a dimming target object is present is reduced when the dimming target object is detected, the dimming target object being an object of which the indicator value is greater than a reference value; a reference-value varying unit configured to set the reference value to a first reference value when the object is detected within the gaze area and set the reference value to a second reference value that is greater than the first reference value when the object is detected outside of the gaze area.

摘要： A method for correcting a light pattern provided by an automotive lighting device, wherein the light pattern is provided at least by a matrix arrangement of light sources. The method includes a first step of projecting a high beam pattern with a first zone where luminous intensity is lower, the first zone having a rectangular edge with four sides. The second step includes providing a number of pixels for each of the four sides of the edge of the first zone, thus creating an upper blur zone, a lower blur zone, a left blur zone and a right blur zone. A final step includes creating a blur pattern for the upper blur zone which extends along columns, a blur pattern for the lower blur zone which extends along columns, a blur pattern for the left blur zone which extends along rows and a blur pattern for the right blur zone which extend along rows, where the luminous intensity in each row or column adapts from the luminous intensity of the first zone to the luminous intensity of the high beam pattern. An automotive lighting device configured to perform these steps is also provided.

摘要： A light distribution controlling device includes a vehicle detector that detects a front vehicle through an image analysis on an image obtained from an imaging device, a region determiner that sets a processing region by adding a margin in a widthwise direction of the vehicle to a presence region of the front vehicle, and a pattern determiner that, in parallel with the detection of the front vehicle, sets a light blocking portion based on a pixel value of a pair of luminous points included in the processing region in the image and determines a light distribution pattern that includes the light blocking portion.

摘要： A headlight control device which recognizes an oncoming vehicle using a camera without dazzling the driver of the oncoming vehicle includes a sequence control section that generates a headlight control signal from an image captured by the camera mounted on the vehicle, and a control value calculation section that calculates a control value for a light distribution pattern in the headlight control signal. An image recognition program includes a license plate recognition section that detects a license plate of the preceding vehicle from the image, and a cut-off line recognition section that detects a cut-off line of the headlight from the image. The control value calculation section calculates the control value for the light distribution pattern such that the cut-off line detected by the cut-off line recognition section is positioned higher by a predetermined height than an upper end of the license plate detected by the license plate recognition section.

摘要： An automotive lamp includes a variable light distribution lamp and a controller. When a first light distribution pattern is to be changed to a second light distribution pattern, and when a difference in the number of shaded portions between the first light distribution pattern and the second light distribution pattern is one, the controller switches a control method for gradually changing the light distribution pattern according to a position relation between the shaded portions included in the first light distribution pattern and the shaded portions included in the second light distribution pattern.

摘要： A vehicle lamp is provided on a vehicle capable of traveling around a corner by inclining a vehicle body in a turning direction. The vehicle lamp includes a headlamp mounted on a front portion of the vehicle, and a combination lamp disposed on a vehicle body cover in a region adjacent to the headlamp so as to be visible from the front of the vehicle. The combination lamp includes a plurality of light emitting segments. Depending on arrangement locations, the light emitting segments differ in at least one of the shape of, the size of, the color of, and a distance between the light emitting segments.
