A method for power optimization in a vehicle/train, using time reserves which are included when planning a schedule, is proposed. In order to achieve a power-saving travel mode with the aid of an optimization algorithm, the presence of a number of completely or partially autonomous drive systems is taken into account, the separate functions of efficiency or power loss of each drive system being taken into consideration.
