  • Patent number: 11813984
    Abstract: An alighting support device performs warning to notify a vehicle occupant of presence of a moving body having a possibility to come into contact with a right door or a left door of the vehicle. The alighting support device performs the warning when a warning condition is satisfied. When the right door or the left door is opened or is about to be opened while the moving body is moving in a right warning area set on the right side of the vehicle or a left warning area set on the left side of the vehicle, the alighting support device determines that the warning condition is satisfied. When the moving body enters the right warning area or the left warning area with the right door or the left door being open to a predetermined degree or more, the alighting support device determines that the warning condition is not satisfied.

  • Publication number: 20220252719
    Abstract: An object detection apparatus is mounted to a vehicle and detects an object by a reflected wave of a probe wave. The object detection apparatus calculates a relative velocity of the object to the vehicle, estimates an azimuth of the object relative to the vehicle, and corrects the estimated azimuth. The object detection apparatus generates a velocity-azimuth curve that indicates a relationship between the relative velocity of the object and the azimuth of the object that is calculated based on a theoretical mounting angle of the object detection apparatus, supplies a weight to an azimuth error that is an error between the velocity-azimuth curve and the estimated azimuth, based on the estimated azimuth, and calculates a correction value of the estimated azimuth by calculating, as an actual mounting angle deviation of the object detection apparatus, a weighted average value of the azimuth error to which the weight is supplied.
