  • Patent number: 10895357
    Abstract: A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.

  • Patent number: 10818214
    Abstract: Provided is a display system for a vehicle. The display system includes a display device installed to be visually recognizable from the outside of a vehicle, and a control device configured to cause the display device to display state information of the vehicle. The control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and the control device changes display of the display device based on the distance.

  • Patent number: 10794559
    Abstract: A vehicle lamp comprises a light source for road surface drawing configured to emit light becoming a light source image, and a projection lens, which has an optical axis extending in a front and rear direction and the light is to pass therethrough. The vehicle lamp can form a plurality of light distribution patterns on a road surface over a range from a position close to the lamp to a position distant from the lamp by the light emitted from the light source and having passed through the projection lens, and the respective light distribution patterns are to be projected on the road surface at states where relative positions between the projection lens and the light source image are different.
