  • Display device for vehicle
    Patent number: 11326893
    Abstract: A vehicle display device calculates a travel distance limit of an own vehicle, based on an energy remaining amount of the own vehicle; calculates a degree of scattering being a numerical value indicating a degree of remoteness between a farthest supply facility farthest from the own vehicle, and other supply facilities present within a predetermined distance from the farthest supply facility; calculates a travelable distance being a distance by which the own vehicle is able to travel, based on the travel distance limit and the degree of scattering; and causes the display to display the calculated travelable distance. In the processing of calculating the travelable distance, the travelable distance is decreased, as the degree of scattering increases.
