Abstract

A method is provided for estimating the range of a motor vehicle based on a quantity of energy carried in the motor vehicle. The method enables a driver to limit a maximum permissible velocity and/or a maximum permissible acceleration and/or a maximum performance level for a comfort system. The method also detects the route profiles surrounding the motor vehicle, in particular an altitude profile and/or a road category. A computer device calculates and displays a still possible range at least on the basis of the limitation which has been carried out, the detected route profiles and the still available quantity of energy.
