Abstract
A method is disclosed for estimating the residual energy of an electric energy accumulator that supplies an electric assistance traction drive of a motor vehicle with electrical energy. The method includes determining a future operating intensity of the assistance traction drive based on at least one input that characterizes the driving style of a section of route lying ahead, and reserving an energy component of a total quantity of energy available from the energy accumulator. The reserved energy component is determined from the determined future operating intensity based on a predefined consumption parameter. The consumption parameter characterizes the drive-specific consumption of electrical energy via the electrical assistance traction drive. The method further includes estimating the residual energy by reducing the total amount of energy available by the reserved energy component.
