Embodiment Construction

[0047] figure 1 Shown is a schematic diagram of a train 1 equipped with a train driver advisory system 3 according to an exemplary embodiment of the present invention. Train 1 is depicted as consisting only of locomotives, also called traction drive units. However, it should be understood that the train 1 may include additional rail cars, such as passenger or freight cars. The train 1 may also comprise a plurality of locomotives, wherein one or more or all of these locomotives are equipped with a corresponding train driver advisory system.

[0048] The train driver advisory system 3 has: a calculation module, such as a processor with a relevant processor memory; a memory for storing data about the journey the train will travel and data about the dynamic behavior characteristics of the train; A display that provides driving advice to the driver.

[0049] The train 1 also comprises a train control unit 2 which is coupled to a train driver advisory system 3 . The train contro...

Abstract

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 (Dseg) 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.

Description

technical field [0001] The present invention relates to train control. In particular, the invention relates to a train driver system for providing driving advice to the driver and a method of generating and providing such driving advice to the driver. Background technique [0002] Typically, trains require a lot of energy to run. Since fossil fuels are scarce resources, it is desirable to operate fuel-powered trains in an energy-efficient manner. Furthermore, energy-efficient operation allows the train to carry less fuel, which in turn reduces the weight of the train and results in a more energy-efficient operation. With electric trains, it is also desirable to run the trains in an energy-efficient manner. Since electrical energy is often partially derived from fossil fuels and trains require electrical power at many different potentially remote locations along the track (which puts significant stress on the distribution grid), energy efficient operation is highly desirab...
