Abstract

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.
