Abstract: Technologies and techniques for displaying a virtual three-dimensional navigation map in a vehicle. A surface of an interior is determined for the vehicle, and a three-dimensional navigation map is loaded. The three-dimensional navigation map is automatically adjusted to the surface, and the adjusted three-dimensional navigation map is represented together with a representation of an ego position of the means of transportation as a virtual, raised model on the surface via an augmented reality display device.

Abstract: A method for ascertaining a refuel savings for a transportation vehicle including determining a desired quantity of fuel; determining a first fuel price of a first filling station and a second fuel price of a second filling station; determining a first additional fuel requirement produced by driving from a current location to a first position of the first filling station and a second additional fuel requirement produced by driving from the current location to a second position of the second filling station; and determining the refuel savings using the desired quantity of fuel, the first fuel price, the first additional fuel requirement, the second fuel price, and the second additional fuel requirement.

Abstract: A method for providing predictive destination positions and/or predictive routes for reaching a destination position, in which the current local position is ascertained and the destination position is automatically derived according to probability aspects on the basis of a comparison between stored driving information from the past and current driving information, wherein n possible destination positions are ascertained, where n?2, with the destination position being offered as an input option for a navigation system and/or the predictive routes with the destination positions being presented simultaneously. Also disclosed is a navigation system.
