  • Patent number: 11951903
    Abstract: A driving assistance system includes an illumination apparatus and a controller. The illumination apparatus is configured to draw an avoidance pattern PTN on a road surface such that it indicates a lane in which the driver's vehicle is to travel or a direction in which the driver's vehicle is to travel. Upon detecting, by a sensor or communication, an obstacle in front of the driver's vehicle, the controller instructs the illumination apparatus to draw the avoidance pattern PTN.
