  • Patent number: 10618458
    Abstract: A vehicle headlight control device is provided with: a pedestrian detection unit which detects a pedestrian; and a headlight control unit which controls an irradiation state of a headlight. When the pedestrian detection unit detects a pedestrian within an irradiation range of the headlight, the headlight control unit executes dimming control for controlling the irradiation state of the headlight so that a periphery of the pedestrian is dimmed. The pedestrian is irradiated with a part of a high beam or a low beam, or marking light emitted from a dedicated light source. A dimming region is formed around the pedestrian by the dimming control, and contrast in brightness between the pedestrian and his/her surroundings can be raised.
    Type: Grant

  • Patent number: 10037692
    Abstract: A traffic sign recognition system includes a display for displaying caution information regarding a traffic sign ahead of a vehicle, and a processor configured to execute a viewing direction detecting module for detecting a viewing direction of a driver, a traffic sign detecting module for detecting the traffic sign, and a road surface condition detecting module for detecting a slippery road surface condition. The processor controls the display to display the caution information regarding the detected traffic sign when the detected viewing direction of the driver is different from a direction of the detected traffic sign, and controlling the display to refrain from displaying the caution information when the detected viewing direction of the driver matches the direction of the detected traffic sign. When the slippery road surface condition is detected, the processor controls the display to display the caution information regardless of the viewing direction of the driver.

  • Patent number: 9865165
    Abstract: A traffic sign recognition system includes a display for displaying caution information of a traffic light, and a processor configured to execute a traffic light detecting module for detecting a traffic light, a bypass lane detecting module for detecting a bypass lane, a line of sight detecting module for detecting a line of sight of a driver, and a vehicle behavior determining module for detecting a traveling direction of a vehicle. The processor controls the display to display caution information when the line of sight is different from a direction of the traffic light, and controlling the display to refrain from displaying the caution information when the detected line of sight matches the direction of the traffic light. The display is refrained from displaying the caution information when the bypass lane is detected and the traveling direction is toward the bypass lane, regardless of the line of sight.

  • Publication number: 20170154227
    Abstract: A traffic sign recognition system is provided, which includes a display unit for displaying, for a driver of a vehicle, caution information regarding a traffic sign, and a processor configured to execute a specific traffic sign detecting module for detecting a specific traffic sign ahead of the vehicle, the specific traffic sign indicating that traveling of the vehicle in a given direction is allowed, and a vehicle behavior determining module for detecting a traveling direction of the vehicle. The processor controls the display unit to display caution information regarding the specific traffic sign when the detected traveling direction of the vehicle is different from the given direction, and controls the display unit not to display the caution information when the detected traveling direction of the vehicle matches with the given direction of the detected specific traffic sign.
