VEHICLE LIGHTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240278716 titled 'VEHICLE LIGHTING DEVICE

The vehicle lighting device described in this patent application includes an illumination unit that projects an image on the road surface around the vehicle, a turn signal unit that activates the turn signal lamp, and a controller that manages the illumination unit.

  • The controller triggers the turn signal lamp to flash on the side of the lane change when the vehicle switches lanes, while also causing the illumination unit to display a lane change image to alert surrounding vehicles of the vehicle's movement.
  • The configuration of the lane change image is adjusted based on the presence and position of a following vehicle traveling behind the vehicle in the adjacent lane.

Potential Applications: - Enhanced safety features for vehicles on the road - Improved communication between vehicles during lane changes - Advanced signaling systems for autonomous vehicles

Problems Solved: - Lack of clear communication between vehicles during lane changes - Limited visibility of lane change intentions to surrounding vehicles - Potential accidents due to misinterpretation of lane change signals

Benefits: - Increased safety on the road for all vehicles - Enhanced communication between drivers and autonomous vehicles - Reduced risk of accidents during lane changes

Commercial Applications: "Smart" vehicle lighting systems for automotive manufacturers Safety technology for autonomous vehicle companies Advanced signaling solutions for transportation companies

Questions about the technology: 1. How does the controller determine the configuration of the lane change image based on the presence and position of following vehicles? 2. What are the potential implications of this technology for future road safety measures?


Original Abstract Submitted

a vehicle lighting device disclosed in this specification comprises an illumination unit that draws an image on a road surface around a vehicle by illuminating the road surface with light; a turn signal unit that causes a turn signal lamp to flash; and a controller configured to control the illumination unit, wherein when the vehicle changes a lane from a first lane to a second lane adjacent to the first lane, the controller causes the turn signal lamp to flash on a lane change side, and causes the illumination unit to draw a lane change image for notifying surroundings of a behavior of the vehicle, and the controller changes a configuration of the lane change image according to at least one of a presence and a position of a subsequent vehicle traveling rearward of the vehicle and along the second lane.
