  • Patent number: 10839235
    Abstract: In a light control system, a captured image of a cruising direction of a vehicle is acquired, and a light source is extracted from the captured image. A probability for estimating a light source to be a vehicle light source originating from a vehicle is calculated based on light source parameters for differentiating the light source. A dark section that is darker than the periphery and is present below the light source in the captured image is extracted. The probability is set to be higher for the light source of which the dark section is extracted. The light source having a probability that is a reference value set in advance or higher is estimated to be a light source of another vehicle. When the dark section that is detected as a shadow of a vehicle is detected, the probability of the light source being a vehicle light source is set to be high.

  • Patent number: 10495753
    Abstract: A computer-implemented method and system are provided. The system includes an image capture device configured to capture image data relative to an ambient environment of a user. The system further includes a processor configured to detect and localize objects, in a real-world map space, from the image data using a trainable object localization Convolutional Neural Network (CNN). The CNN is trained to detect and localize the objects from image and radar pairs that include the image data and radar data for different scenes of a natural environment. The processor is further configured to perform a user-perceptible action responsive to a detection and a localization of an object in an intended path of the user.

  • Patent number: 10486586
    Abstract: Method and apparatus are disclosed for control of vehicle headlights based on weather conditions. An example vehicle includes headlamps including low-beam lamps and high-beam lamps. The example vehicle also includes a light sensor, a camera, and a controller. The controller is to set the low-beam lamps in active mode when the light sensor detects low ambient light, monitor for precipitation in the low ambient light via the camera, identify an angle-of-incidence (AOI) between the precipitation and light emitted by the headlamps, and control the high-beam lamps based on the AOI.

  • Patent number: 10427592
    Abstract: A method and system for controlling exterior lights on a vehicle. The method includes receiving an input indicative of a desired mode of operation of the exterior lights from a user-selectable input device. The user-selectable input device includes an on-setting, an off-setting, and an automatic-setting. The method further includes receiving sensor data indicative of a level of visibility outside the vehicle, comparing the sensor data to a threshold, and generating, by an electronic processor, a notification indicative of an improper positioning of the user-selectable input device when the sensor data indicates that the level of visibility is less than the threshold and the user-selectable input device is positioned in the off-setting.
