摘要： Speed of a vehicle is acquired from a speed detecting device, and then a beam switching threshold, according to the acquired speed, of an irradiation direction of a headlight is initially set. When the number of appearance (i.e. frequency of appearance) of a light source in a predetermined time detected by a light source detection means have become the beam switching threshold or more, the headlight is switched to a low beam. When a predetermined time (beam switching prohibition time Tp) has been passed after the irradiation direction of a headlight was switched to the low beam, the irradiation direction of the headlight is switched to a high beam.

摘要： A headlight control device automatically switches a light distribution pattern of a headlight for illumination ahead of a vehicle. The headlight control device including an imager that sequentially takes images of a view ahead of the vehicle in a predetermined frame rate, an another-vehicle recognizer that recognizes a light source of another vehicle from each of the images sequentially taken by the imager, a light distribution controller that switches the light distribution pattern according to a recognition result of the another-vehicle recognizer, and a signal provider that provides a signal to illumination light of the headlight by causing the luminance of the headlight to change in a predetermined cycle. The another-vehicle recognizer recognizes, as reflected light of the headlight of the vehicle, a light source which is present within the image and of which luminance change is substantially similar to a luminance change of the signal.

摘要： An image sensing system for a vehicle includes an imaging sensor and a control. The imaging sensor has a two-dimensional array of light sensing pixels, and has a forward field of view through the windshield of a vehicle equipped with the image sensing system to the exterior of the equipped vehicle. The imaging sensor is operable to capture image data and the control includes an image processor. The image sensing system determines an object of interest present in the forward field of view of the imaging sensor via processing of the captured image data by the image processor. The image processing includes spatial filtering. The spatial filtering may, at least in part, identify atmospheric conditions. The spatial filtering may include analysis of a spectral signature representative of at least one detected light source present in the forward field of view of the imaging sensor.

摘要： A system and method for intelligently controlling headlights receive a multiplicity of images that represent frames of a video sequence of an external environment of a vehicle. At least one bright spot, or blob, is found that stands out from a dark background of the external environment within each frame of the multiplicity of images. A multiplicity of features is extracted from a found blob. A type is recognized of a found blob that is selected from a multiplicity of types of blobs. A determination is then made whether to turn on a high beam light or a low beam light based at least on the recognized type of the found blob and a set of rules. Finally, an action based on such decision is performed.

摘要： A vehicle headlamp control method and apparatus includes providing an imaging sensor that senses light in spatially separated regions of a field of view forward of the vehicle. Light levels sensed in individual regions of the field of view are evaluated in order to identify light sources of interest, such as oncoming headlights and leading taillights. The vehicle's headlights are controlled in response to identifying such particular light sources or absence of such light sources. Spectral signatures of light sources may be examined in order to determine if the spectral signature matches that of particular light sources such as the spectral signatures of headlights or taillights. Sensed light levels may also be evaluated for their spatial distribution in order to identify light sources of interest.
