Abstract

A method is provided for increasing the operating range of a vehicle which is driven by an electric motor. The method determines that a state of charge reserve of an energy store of the vehicle should be used for operating the electric motor. The state of charge reserve lies outside a state of charge range which is intended for the energy store. In response to this, the method uses electrical energy from the state of charge reserve of the energy store in order to operate the electric motor of the vehicle.
