METHOD OF PROVIDING A DRIVING RECOMMENDATION TO A DRIVER OF A TRAIN AND TRAIN DRIVER ADVISORY SYSTEM

摘要

A method of providing a driving recommendation to a driver of a train (1) during operation of the train is disclosed. The driving recommendation is based on a distance (D seg ) and an altitude profile (32) of a trip segment to be covered by the train, a travel time limit for the trip segment, and velocity limits (20) along the trip segment. The method includes the steps of defining an initial state (10) of the train on the basis of an actual position of the train and an actual velocity of the train; defining a goal state (12) of the train on the basis of a goal position and a goal velocity at the end of the trip segment to be covered by the train; determining an energy-optimized velocity profile (18) between the initial state of the train and the goal state of the train, with the energy-optimized velocity profile being determined by a graph based optimization algorithm, constrained by the travel time limit for the trip segment and the velocity limits along the trip segment; and providing the driving recommendation to the driver on the basis of the energy-optimized velocity profile.
