  • Patent number: 10336253
    Abstract: A vehicle side obstacle detecting and warning method is applied on a vehicle. The vehicle side obstacle detecting and warning method includes providing a measuring step for measuring a dataset of the vehicle. The vehicle side obstacle detecting and warning method includes providing a detector installing step for positioning a plurality of detectors between the front wheel and the rear wheel according to the maximum inner wheel difference area. The vehicle side obstacle detecting and warning method includes providing a detected area adjusting step for adjusting a detecting distance or a positioning angle of at least one of the detectors to form a detected area. The vehicle side obstacle detecting and warning method includes providing a detecting and warning step for sending a warning message by a warning module disposed at the vehicle when an obstacle is detected by any one of the detectors within the detected area.

  • Publication number: 20180362083
    Abstract: A driving state warning method is used for judging a driving state by a vehicle path of a vehicle. An image recognizing step is for providing an image capturing device to capture an image and recognize a lane marking of a vehicle lane according to the image. A vehicle speed judging step is for providing a vehicle speed capturing device to judge an actual vehicle speed. A crossing lane judging step is for providing a processing unit to judge whether or not the vehicle is crossing the lane marking according to the image. A consciousness judging step is for calculating a displacement of the vehicle according to the image by the processing unit and comparing whether or not the displacement is greater than a threshold value for judging consciousness of the driver. Therefore, the present disclosure can easily perform installations without any directional light detecting device.

  • Patent number: 8600111
    Abstract: The present invention discloses a vehicular tilt-sensing method and an automatic headlight leveling system using the same. The method of the present invention comprises steps: using an image capture device to capture an image of the road and obtain at least one instantaneous lane marking line from the image; extending the instantaneous lane marking lines afar to obtain an instantaneous vanishing point; establishing an instantaneous horizontal line passing through the instantaneous vanishing point; calculating from the image the displacement between a datum horizontal line and the instantaneous horizontal line; and calculating the tilt angle with the displacement and the focal length of the image; using the tilt angle to generate a control signal to control level adjusting controllers to adjust headlights, whereby the headlights can provide optimized illumination to enhance night driving safety on a rugged road or in the case that the vehicle is unevenly loaded.

  • Publication number: 20110253524
    Abstract: An aluminum-scandium (Al—Sc) alloy film applied to vehicle lamps and a manufacturing method thereof are revealed. The Al—Sc alloy film contains a trace of scandium so that both temperature for grain refinement and temperature for recrystallization of the film are increased. This results in a fine and smooth surface of the Al—Sc alloy film and the Al—Sc alloy film has better optical reflectivity. Moreover, the Al—Sc alloy film has high recrystallization temperature and high adhesion strength. After high temperature annealing treatment, the Al—Sc alloy film still has higher corrosion resistance.
