Method for displaying the operating range of an electric drive vehicle, and display

摘要

A method and display for displaying the operating range of an electric drive vehicle and a display for carrying out same are provided. The battery energy in a vehicle is detected, and a maximum operating range of the vehicle is determined therefrom. At least one battery service station is selected as destination point for determining the maximum operating range. Based on a starting point, a reachability threshold is determined. If exceeded, the vehicle will be unable to reach the destination point with the current battery energy available, wherein said reachability threshold is displayed as an operating range in a map illustration. During the determination of the reachability threshold, the current location is used as the starting point and the current battery energy of the vehicle is used, both of which are updated at pre-defined intervals while the vehicle is moving.

主权项

1. A method for displaying (12) an operating range of an electric drive vehicle, the method comprising:
determining battery energy in the vehicle with a sensor; deriving from the determined battery energy a maximum operating range of the vehicle; selecting, as respective destination points (15, 15′) for determining the maximum operating range (16), a plurality of different battery service stations, wherein all selected destination points (15, 15′) for determining the maximum operating range (16) are battery service stations; determining an accessibility threshold (16) using a starting point (14) as a basis, beyond which the vehicle can no longer reach at least one of the plurality of destination points (15, 15′) with the derived battery energy; and displaying, by a display unit (13), the determined accessibility threshold (16) as an operating range in a map illustration, wherein the determination of the accessibility threshold (16) uses a current location of the vehicle as the starting point (14) and the current battery energy of the vehicle, the current location and the current battery energy of the vehicle being updated at predeterminable intervals while the vehicle is traveling.
