Abstract

A method is proposed for power optimization in a vehicle/train, using time reserves which are included when a schedule is planned, an overall route to be covered between a starting stop and a destination stop being subdivided into a number of sections and each section being assigned a specific time reserve. In order to achieve a power-saving travel mode with the aid of an optimization algorithm, in each case only a limited route area, comprising a predefined number of sections, is taken into consideration for the optimization. The results of the optimization are implemented only for the first section of the route area. The optimization calculation is repeated cyclically during the journey of the vehicle/train, the route area being considered being moved together with the vehicle.
