Definitions
- the invention relates to a method for speed control of a rail vehicle.
- Speed control means the specification or recommendation of a speed that is particularly favorable with regard to safety aspects and energy consumption.
- a rail vehicle When driving a rail vehicle, its speed is usually based on the one hand according to the train speed and route permissible train speed and on the other hand according to a predetermined signaling on the route side.
- a driving profile specified for the rail vehicle takes into account an energy-saving driving style. Further measures to reduce energy consumption consist in minimizing energy losses along the energy transmission path from the power plant to the wheel drive of the rail vehicle, and in reducing weight and air resistance.
- the invention has for its object to provide a method for speed control of a rail vehicle, with which a further reduction in energy consumption is possible.
- a permissible driving speed is determined on the basis of the current distance between the rail vehicle and a signal on the route and the earliest point in time for a signal indicating a journey. If this driving speed, which is optimized with regard to energy consumption, is used as a guideline speed, considerable energy savings are achieved.
- the invention is based on the consideration that during a train journey between two stopping points usually four phases are run through, of which a start-up or acceleration phase and a speed stop phase require energy consumption, while in a run-down phase and in a braking phase there is no energy consumption.
- an acceleration phase can take place from a minimum speed level due to a avoided vehicle stop or standstill. This can shorten the acceleration phase and thus reduce energy consumption.
- a method for guiding the speed of a rail vehicle in front of a signal is known from German Offenlegungsschrift DE 30 47 637 AI; In this method, the rail vehicle is always braked to a constant release speed in accordance with a predefined setpoint speed curve; an energy-optimized driving speed is not determined.
- the current speed of the rail vehicle is expediently additionally used to determine or calculate the permissible travel speed.
- a recommended driving speed can also be set via a cyclical evaluation of the train or vehicle location.
- taking the current speed into account has the advantage that the or each phase-out phase of the rail vehicle can be included directly in the calculation using algorithms.
- the driving speed is expediently determined on the route side in a dispatch center. This gives provide the rail vehicle with a reduced speed in good time provided that there is no need to follow a vehicle standstill.
- This speed recommended by the dispatching or control center is expediently signaled to the driver's cab of the rail vehicle.
- Safety technology still specifies the maximum permitted speed and automatically initiates braking in the event of a malfunction.
- the additional speed recommended by the control system is determined from the point of view of energy consumption. For this purpose, the location of the rail vehicle and the distances to the following signals as well as the times at which the signals can indicate a travel term and possibly the current speed of the rail vehicle are taken into account.
- a recommended driving speed is expediently displayed, which does not exceed the safety speed.
- a maximum possible length of a run-out phase is also taken into account to determine the driving speed.
- a particularly favorable length of a speed holding phase can also be taken into account when determining the driving speed.
- the advantages achieved with the invention consist in particular in that considerable energy savings are achieved by specifying a driving speed that reduces energy consumption and thus by driving ahead. By specifying the driving speed, unnecessary vehicle downtimes can be avoided, so that at least a part of the otherwise required acceleration phases is saved. Further energy savings can be achieved by reducing the speed at an early stage, since their amount also significantly affects energy consumption.
- Predictive driving based on the specification of a driving speed improves energy consumption in both respects.
- the resulting even driving style also reduces wear on the vehicle and improves the well-being of the passengers.
- the initiation of an acceleration phase from a comparatively high speed level also results in an increased throughput.
- FIG. 1 schematically shows a rail vehicle connected to a control center for determining a driving speed and FIG. 2 shows a driving curve when driving ahead with a speed / energy path diagram.
- the rail vehicle 1 according to FIG. 1 is connected to a control or dispatch center 2 via a radio link.
- a vehicle device 3 is provided on the rail vehicle 1.
- the functionality of the vehicle device 3 also includes the display of a travel speed v 'determined with regard to the energy consumption.
- a module 4 for speed calculation is additionally provided in the dispatch center 2.
- the module 4 receives as input data the / distance d between the rail vehicle 1 and one projected signal location x 2 as well as an earliest point in time t for a signal 5 indicating a journey or showing a release, and expediently additionally the current speed v of the rail vehicle 1.
- the current speed v is transmitted to the dispatch center 2 via a radio channel 6.
- a speed calculation takes place in module 4, taking into account a run-down phase ⁇ x (FIG. 2), starting from the current speed v.
- the driving speed v ′ determined from these data d, t, v is transmitted to the rail vehicle 1 via the radio channel 6.
- the driving curve FK takes into account energy-optimized and thus anticipatory driving.
- the speed v and the energy E along a travel path x are shown.
- the driving curve FK is composed of a run-down phase A and a subsequent speed holding phase H as well as an acceleration phase B and a subsequent further speed holding phase H '.
- the dashed line shows the energy E absorbed by the rail vehicle 1 in the respective phases A, H, B, H '. It can be clearly seen that no energy is absorbed by the rail vehicle 1 during the phase-down phase A, while the acceleration phase B does not Energy consumption is particularly high.
- an energy-optimized driving speed v ' in particular the length ⁇ x of the run-down phase A is optimized, so that acceleration takes place in the acceleration phase B from a minimum speed level. This shortens the acceleration phase B, which leads to energy savings.
