The invention relates to a method for controlling a railway vehicle having a double drive system, wherein each drive system comprises an internal combustion engine and a transmission unit, wherein a target drive torque (M(SL)) is provided as a power requirement by means of a drive lever, wherein an actual drive torque (M(IST)) of the railway vehicle is determined and a drive torque deviation is calculated from the target drive torque (M(SL)) and the actual drive torque (M(IST)). The method further comprises determining a prediction drive type (AAP), and a target drive type (AA(SL)) in the sense of a single or double drive, a target operating point (BP(SL)), and a target transmission stage (US(SL)) are set for the transmission units, based on the drive torque deviation and the prediction drive type (AAP), by means of a traction manager ().

Method for controlling a railway vehicle

A method is proposed for controlling a hybrid drive in a rail vehicle in which an electronic route timetable (SPL) is predefined as route-section-related speeds by means of a train control device, route-section-related types of drive for the rail vehicle are predictively determined by means of the electronic route timetable (SPL) before the journey begins, a deviation of the actual position from a setpoint position of the rail vehicle which is obtained from the electronic route timetable (SPL) is determined while the rail vehicle is travelling, a time margin is calculated on the basis of the difference in position, and the current type of drive is retained or changed as a function of the time margin.
