Definitions
- the invention relates to a method for energy optimization of the driving style in a vehicle / train with a total route divided into several sections according to the preamble of claim 1.
- time reserves for unforeseen events and adverse operating conditions are planned. Since the operating conditions are typically more favorable during real journeys than assumed in the planning, the resulting time reserves are available for other purposes.
- a particularly sensible use of the time reserves consists in saving energy by means of a suitable driving style of the vehicle / train.
- the uncertainty in the operational sequence due to the time reserves provided in the timetable, is highest at the start stop (start station) and decreases continuously with increasing approach to the destination stop (destination station).
- the decrease in uncertainty is traditionally taken into account in route timetables in the form of transit times for selected route points.
- the time reserve is distributed evenly over the entire route.
- DE 30 26 652 AI and EP 0 467 377 B1 deal with a system structure in which methods for minimizing energy can be implemented, taking into account a total distance between two stopping points (stopping stations). For long distances, this can lead to real-time specifications for the solution being disadvantageously not met by the method.
- the invention has for its object to provide an improved method for energy optimization of the driving style in a vehicle / train with the total route divided into several sections.
- the advantages that can be achieved with the invention are, in particular, that the robustness of the operational sequence is increased by the inclusion of flexible management of time reserves with the aid of an optimization algorithm.
- the driving style implemented is optimal in terms of energy.
- robustness it is meant that even with long total distances and unforeseen events, a timely arrival of the vehicle / train at the destination stop is guaranteed with high probability.
- the invention is explained below with reference to the embodiment shown in the single drawing.
- the figure shows the path / time diagram of a vehicle, the entire route being divided into several individual sections and i representing the running index for the individual sections.
- the appropriate number of sections for a preliminary calculation is designated with n.
- the latest transit times are marked with triangles.
- a time window is also given as an example. The time window determines at which earliest and latest transit time a particular section of the vehicle is to be passed.
- time reserves are flexibly included in the energy optimization.
- Time reserves are provided in order to be able to react to unforeseen events and thus increase the robustness of the traffic flow.
- a time allowance of 5%, for example, is typically granted.
- This time surcharge is distributed evenly over the entire route, for example, so that transit times can be determined at any route point.
- the inclusion of the time reserves takes place in such a flexible manner that the time reserve not used in a route section is added proportionately to the subsequent route sections and in such a way that the time reserves due to the individual route sections are evaluated differently.
- the consumption of time reserve in a section of the route is taken into account in the optimization as a "penalty term".
- a monotonically falling function of time comes into consideration as the "penalty term”.
- the consumption of time reserve is less "punished” the further it takes place in the future, i.e. closer to the destination stop.
- the transit times in the optimization problem are recorded as boundary conditions in such a way that on the one hand the required robustness is guaranteed, but on the other hand the solution that is optimal for energy saving is impaired as little as possible.
- the required robustness it is sufficient if the latest transit times are required. These latest transit times are entered as triangles in the figure, as already mentioned.
- a higher-level operations control center can therefore provide the vehicle with short-term specifications for transit times in the form of time windows.
- Such a time window is entered as an example in the figure, as already mentioned.
- Resulting time windows are included in the optimization as an earliest and a latest transit time.
