Abstract

An operating strategy for the components of the drive train is defined as a function of data which characterizes a route to be traveled along. Depending on the operating strategy and the route data, expected energy consumption and a time period for which the energy can be made available are calculated. If the time period is detected as being sufficient, the drive train is controlled in accordance with the operating strategy. If the calculated time period is detected as not being sufficient, an alternative operating strategy is defined and the resulting time period is checked again.
