  • Patent number: 11801867
    Abstract: A vehicle control device of a vehicle includes: an action plan creating part that creates an action plan for autonomous driving by the vehicle; and a distance detection part that outputs detection information on detection of an object. The action plan creating part includes a collision probability map setting part configured to, when the distance detection part detects an obstacle, determine a collision probability map, which is a two-dimensional map of a collision probability distribution representing likelihood of a collision between the vehicle and the detected obstacle in a two-dimensional space of a location and a speed. The action plan creating part is configured to create a current action plan based on the collision probability map, a predetermined target collision probability, and a current location and a current speed of the vehicle.

  • Patent number: 11180166
    Abstract: Provided is a vehicle control device which, when traffic participants are waiting in the vicinity of a railroad crossing for a train to pass, appropriately controls driving of a vehicle about to pass through the railroad crossing. Entry of the vehicle into the railroad crossing is restrained until a waiting time elapses since when the railroad crossing transitioned from a passage blocking state to a passage allowing state, the waiting time being set in accordance with the kind or the number of the traffic participants present in the vicinity of the railroad crossing. When the waiting time has elapsed, the vehicle is caused to enter the railroad crossing and pass (through) the railroad crossing.

  • Publication number: 20190228743
    Abstract: A less-distorted output video is displayed regardless of a viewpoint position of a user. A rendering unit (20) increases the number of pixels of an input video and generates an output video obtained by enlarging the input video. The rendering unit (20) continuously changes an enlargement ratio of the output video with respect to the input video on a display unit (30) so that an amount of an increase in the number of pixels of the output video with respect to the input video is increased as a position on the display unit (30) is farther from a reference position.
