  • Patent number: 9511708
    Abstract: A method and system are provided to image an external scene by employing a custom image sensor. The custom image sensor may use a GRRB array to filter the images of oncoming and preceding vehicle taillights captured by a vehicle camera. The method and system may also calculate a GRRB color metric for use in the custom image sensor by performing interpolation on a number of color channels, summing the brightness values for each of the color channels interpolated, normalizing each of the brightness values, and converting the normalized brightness values from an RGB scale to a linear scale of non-red to red.

  • Patent number: 9317758
    Abstract: An imaging system is provided for a vehicle. The system includes an imager for imaging a forward external scene and generating image data corresponding to the acquired images; and a processor for receiving and analyzing the image data to detect a light source. When a light source is detected, the processor generates a control signal to control exterior lights of the vehicle to temporarily modulate an illumination pattern projected from the exterior lights to have a particular modulation pattern. After generating the control signal, the processor analyzes the image data subsequently received to detect whether the light source has the modulation pattern of the exterior lights. If the light source does have the modulation pattern, the processor determines that the light source is a reflective object and not a light of another vehicle. Otherwise, the processor determines that the light source may be a light of another vehicle.

  • Patent number: 9187029
    Abstract: An exterior light control system is provided for controlling exterior lights of a vehicle. The system includes an imaging system configured to image a forward external scene and to generate image data corresponding to the acquired images; and a controller configured to receive and analyze the image data and for generating an exterior light control signal that is used to control the exterior lights in response to analysis of the image data and in response to a selected mode of operation. When in the motorway mode, if the controller detects headlamps of one or more oncoming vehicle, the controller generates an exterior light control signal for reducing the brightness of the exterior lights, determines a relative location within the acquired images of a headlamp closest to a central feature of the acquired images, and selects a delay that varies dynamically in response to the relative location of the headlamp.

  • Patent number: 8983135
    Abstract: A system for controlling equipment of a vehicle is provided. The system is configured to image a scene external and forward of the controlled vehicle and to generate image data corresponding to acquired images including a controller for receiving and analyzing the image data and for generating a control signal in response to analysis of the image data and in response to a selected mode of operation. The controller analyzes the data in order to detect at least one characteristic in the image data and selects a mode of operation from at least one of the following modes of operation: the controller selects a dark village mode if at least one characteristic reaches a first threshold, a bright village mode if at least one characteristic reaches a second threshold, and a non-village mode if the controller is not operating in either the dark village mode or the bright village mode.

  • Publication number: 20150061493
    Abstract: An imaging system and method for fog detection are disclosed herein. An imager is configured to image a scene external and forward of a controlled vehicle and to generate image data corresponding to the acquired images. A controller is configured to receive and analyze the image data. When exterior lights of the controlled vehicle are operated in a low beam state, the controller is able to detect light sources of interest in the image data, determine if each light source of interest is a foggy light or a clear light, and generate a first signal if a fog entry condition is satisfied.

  • Patent number: 8964024
    Abstract: An exterior light control system is provided for controlling exterior lights of a vehicle. The system includes an imaging system configured to image a forward external scene and to generate image data corresponding to the acquired images; and a controller configured to receive and analyze the image data and for generating an exterior light control signal that is used to control the exterior lights in response to analysis of the image data. The controller is further configured to analyze the image data to detect a semi-truck. When a semi-truck is detected, the controller generates an exterior light control signal that indicates the detection of a semi-truck or simply the presence of an oncoming vehicle. The controller may detect groups of lights belonging to a semi-truck other than headlamps, e.g., cab lights, so that a semi-truck may be detected even when the headlamps of the semi-truck are not detected due to being blocked by a roadside barrier.
