Definitions
- the invention relates to a method for calibrating a chassis control system of a rail vehicle, as well as a rail vehicle and a computer program product for carrying out the method.
- the horizontal dimension changes continuously from platform to vehicle.
- the vehicle is adjusted using shims in the chassis area so that the vehicle lands within the permissible tolerance range. This also happens after the wheels have been turned off.
- This requires complex measurements of the vehicle and sometimes quite complex calculations of the deflection of the car body and tolerance analyzes in order to add individual inserts, as well as constant checking during production or Maintenance necessary.
- the invention is based on the object of simplifying the commissioning, operation and maintenance of rail vehicles.
- a method for calibrating a chassis control system of a rail vehicle comprises the following method steps: a. Detecting at least one value of a vehicle height of a rail vehicle relative to an upper edge of a platform on the track of the rail vehicle by means of at least one suitable measuring device of the rail vehicle; b. Adjusting a predetermined value of a chassis height depending on the at least one recorded value of the vehicle height by a suitably designed chassis control of the rail vehicle.
- a rail vehicle according to the invention is set up to carry out the method according to the invention.
- it includes the means already mentioned that are suitable for carrying out the respective process step:
- At least one measuring device for detecting at least one value of a vehicle height of a rail vehicle, in particular at least one car body of a rail vehicle, relative to an upper edge of a platform on the track of the rail vehicle;
- the rail vehicle is located on a track in front of the platform. It can be standing on the platform or, especially slowly, driving past it.
- the fixed point can e.g. B. a passenger entrance, i.e.
- a platform is usually designed to be flat so that its surface for entry - its platform surface - lies on a level with its upper edge.
- the measuring device can, for example, be designed and aligned to detect a platform surface and a step bar in the entrance area of the rail vehicle in order to detect a distance between the platform surface and the step bar and thus a vehicle height relative to the top edge of the platform.
- the rail vehicle comprises, as a suitable measuring device for detecting the at least one value of the vehicle height of the rail vehicle relative to the upper edge of the platform on the track of the rail vehicle, at least one sensor for monitoring at least one passenger entrance of the rail vehicle.
- This is suitably designed, for example as a lidar sensor, and arranged in or on the rail vehicle and at least partially aligned with the platform.
- Process step a. is carried out in accordance with the further development by means of the at least one sensor for monitoring passenger boarding of the rail vehicle. Sensors for monitoring passenger boarding can be used to measure the distance from the passenger boarding to the platform, e.g. B.
- Measured values for the height of a passenger entrance above the upper edge of a platform can be used to adjust the level of the passenger entrance to the platform by means of a movable step platform arranged in the area of the passenger entrance.
- step a recorded at least one value of the vehicle height of the rail vehicle relative to the upper edge of the platform on the track of the rail vehicle, if necessary pre-processed, transmitted to a chassis control.
- a predetermined chassis height of at least one chassis of the rail vehicle is adjusted as a function of the measured vehicle height by the chassis control.
- the chassis control is suitably designed to receive the at least one detected value of the vehicle height, to process it further and to adjust the value of the chassis height of the at least one chassis of the rail vehicle, which is predetermined as normal, depending on the at least one detected value of the vehicle height.
- the adjusted value of the chassis height can be saved by the chassis control, for example in a memory of the chassis control.
- the adjusted value of the vehicle height can then be used to regulate the chassis by the chassis control system.
- process step b follows: c. Controlling a chassis height of at least one chassis of the rail vehicle depending on the adjusted value of the chassis height by means of the suitable trained chassis control of the rail vehicle.
- the chassis height is determined, among other things, by the height of the chassis' secondary suspension.
- Secondary springs are designed, for example, as height-adjustable air springs.
- the rail vehicle has at least one chassis with air suspension, in particular as a secondary suspension, with a height of the air suspension being regulated depending on the adjusted value of the chassis height by means of the suitably designed chassis control of the rail vehicle.
- the height of the air suspension is controlled, for example, by increasing or decreasing the filling pressure in the air spring.
- a vehicle height i.e. the height of the rail vehicle car body supported on the chassis above the rail and thus also above the platform, is regulated depending on the adjusted and stored value.
- the chassis control is assigned to the at least one chassis of the rail vehicle and is designed to regulate the height of the at least one chassis.
- the rail vehicle can have a plurality of interconnected car bodies. Each car body can rest on one or more, especially two, chassis. So-called Jacobs bogies are also known, on which two car bodies are supported.
- the car bodies can also each have several doors.
- at least one value of the vehicle height of the car body of the rail vehicle relative to the upper edge of the platform on the track of the rail vehicle is recorded by means of the at least one suitable measuring device of the rail vehicle. If necessary, at least one value of the driving time is displayed on each door of the car body. Vehicle height of the car body of the rail vehicle compared to the top edge of the platform is recorded.
- the predetermined values of the respective chassis height can be adjusted depending on the recorded values of the vehicle height of the car body correspondingly supported on the chassis by the suitably designed chassis control of the rail vehicle.
- the height of each chassis can be adjusted individually.
- the height of the running gear can be controlled depending on several recorded values of the vehicle height of the rail vehicle, for example by forming an average value or a median over the several recorded values of the vehicle height of the rail vehicle and using this mean value or median to adjust the respective predetermined values of the running gear heights become .
- process step a repeated on a predetermined number of platforms and method step b.
- an average value or a median is formed from the corresponding plurality of recorded values of the vehicle height, in particular by means of the suitably designed chassis control of the rail vehicle, in method step b.
- the value of the chassis height specified as normal is adjusted depending on the mean value or the median formed by the suitably designed chassis control of the rail vehicle. This can be done individually for each car of the rail vehicle.
- Known sensors for monitoring passenger entrances are also used to provide height differences from the platform to the rail vehicle's door sills as a control variable for the chassis heights. This means that the running gear can regulate each passenger entrance on the train to the optimal height in order to achieve a level entrance, even with larger height differences. This can be accompanied by a significant cost reduction in the planning and implementation of measures that are conventionally carried out in order to meet the permissible height of the door sill over the entire period of use of the vehicle.
- method step b follows. according to : d . Reading out the at least one adjusted value of the chassis height of the at least one chassis of the rail vehicle from the chassis control; e. Determining a deviation of the at least one adjusted value of the chassis height from the originally specified value of the chassis height; f. Selecting at least one wheel wear pad, in particular its thickness, depending on the determined deviation of the adjusted value of the chassis height from the originally specified value of the chassis height; g. Mount the selected wheel wear pad on the chassis and h.
- Process step e. can precede: transmitting the at least one adjusted value of the chassis height of the least at least one chassis of the rail vehicle from the chassis control to a service or maintenance center. At least the assembly of the wheel locking inserts is carried out in the service or maintenance center, also known as a depot.
- the transmission between the rail vehicle and the land-based service or maintenance center can be carried out wirelessly. Then both the rail vehicle is suitably equipped for sending and the land-based service or maintenance center for receiving.
- process step d takes place. takes place in the shore-based service or maintenance center, also wirelessly or wired.
- Process step e. can also take place in the landside service or maintenance center or can already be carried out by the chassis control of the rail vehicle. Accordingly, in process step d. In addition to the adjusted value of the chassis height, its deviation from the value of the chassis height that was originally specified as normal can also be read out and, if necessary, transmitted.
- a new value for the chassis height is specified as normal in the chassis control.
- the other adjusted value of the chassis height that may still be stored can be deleted accordingly.
- Process step f is further developed. Ahead :
- Specifying a new value of the chassis height in the chassis control depending on the determined deviation of the adjusted value of the chassis height from the originally specified value of the chassis height and depending on the determined deviation of the at least one recorded value of the diameter of the at least one wheel of the rail vehicle before and after turning and depending, in particular, on the thickness, of the mounted wheel wear pad, especially for height adjustment of the chassis.
- the values mentioned each relate to a chassis on which the relevant car body, whose vehicle height was recorded, rests.
- the relevant chassis control is, as already explained above, responsible for regulating the chassis.
- the new specified value of the chassis height in the chassis control can also depend on other parameters be specified, for example depending on, for example, dimensional changes on the chassis or on the car body caused by settling behavior, material fatigue or wear, for example of primary springs, the secondary spring or previously introduced wheel wear inserts, etc.
- the use of the at least one sensor serves to monitor passenger entry or the use of the vehicle height values detected by this sensor to calibrate the chassis control, in particular the height control, of the at least one chassis of the rail vehicle.
- the level of the track can be adjusted so that the rail vehicle entrances are at the same level as the platform.
- the chassis or of the chassis ad hoc but relatively complex. Therefore, such height differences can be advantageously compensated for with movable step platforms, so that the rail vehicle can be entered or exited in a stepless and barrier-free manner, in particular flat.
- a height level of the rail vehicle is preferably set over the entire length of time by means of the height control of each chassis.
- different wear or settling behavior of the wagons have to be compensated for and, on the other hand, the rail vehicle has to be adjusted to a known route that is to be traveled and its maintenance has to be significantly simplified.
- the height of the rail vehicle can be easily adjusted so that all platforms on the route and accessed are within a specified tolerance.
- the individual platform heights usually only vary slightly, which can be compensated for by sliding steps or step platforms, as long as the vertical distances between the entrances and the platforms are within the specified tolerance.
- the invention is suitable both for rail vehicles with sliding steps and for use on rail vehicles with fixed step bars.
- a computer program product according to the invention comprises commands which, when the program is executed by a suitable mobile terminal, cause it to carry out the method according to the invention.
- a provision device for the computer program product stores the computer program product and/or makes it available for execution.
- the provision device is in particular a data carrier on which the computer program product is stored.
