- the brake is preferably a friction brake.
- the vehicle-side torque is determined at least as a function of the brake force
- the braking torque is determined using a pneumatic pressure that governs a slip to regulate the braking force of the brake.
- the controller output value of the control device is preferably multiplied by a vertical force value which is determined using the computing module and indicates the vertical force acting on the rotating part.
- the vertical force is preferably determined as a function of the driving situation, taking into account the distribution of mass to the wheels of the rail vehicle, which depends on the driving situation; alternatively, it can be calculated independently of the driving situation-dependent mass distribution, for example by forming the quotient between the total mass of the rail vehicle and the total number of wheels, with the acceptance of a corresponding measurement error.
- the invention also relates to a method for operating a rail vehicle. According to the invention, with regard to the latter method, it is provided that a parameter indicative of the frictional connection between a rotating part and a rail traversed by the rotating part a method as described above is measured with the formation of a measured parameter value and at least one driving and/or braking parameter is adjusted during the journey as a function of the parameter measured value measured during the journey.
- the invention also relates to a method for parameterizing a rail vehicle.
- a parameter indicating the frictional connection between a rotary part and a rail on which the rotary part travels is measured according to a method as described above, forming a large number of measured parameter values that have a parameter measured value profile of the reference route, and at least one control or regulation parameter influencing the driving and/or braking behavior of the rail vehicle is determined within the framework of travel simulations, which are carried out taking into account the course of the measured parameter values for the reference route, and with the control or regulation parameter thus determined, the rail vehicle for future trips is parameterized.
- the invention also relates to a measuring device for a rail vehicle for measuring a parameter relevant to the travel of the rail vehicle while forming a measured parameter value.
- the measuring device is designed in such a way that the measured parameter value describes the frictional connection between a rotating part and a rail traveled by the rotating part, with the measuring device determining the measured parameter value using a control loop in which
- a vehicle-side torque acting on the rotating part is determined by forming a vehicle-side torque value

- the controller output value of the control device and/or the newly calculated adhesion torque value is regarded as the measured parameter value to be measured, in particular stored or output.
- the device can carry out all of the above method steps individually or in any combination.
- the invention also relates to a rail vehicle with a measuring device as described above.
- the rail vehicle can carry out all of the above method steps individually or in any combination.
- the rail vehicle is preferably also equipped with a
- Equipped vehicle control device designed in such a way What is required is that, while driving, it adjusts at least one driving and/or braking parameter as a function of the measured parameter value of the measuring device.
- the rail vehicle is parameterized with at least one control or regulation parameter which has been determined on the basis of a parameter measured value curve measured by the measuring device for a reference section.
- FIG. 1 shows an exemplary embodiment of a rail vehicle according to the invention, which is equipped with an exemplary embodiment of a measuring device according to the invention
- FIG. 1 shows an exemplary embodiment of a rail vehicle 10 which is equipped with a measuring device 100 for measuring a parameter relevant to the travel of the rail vehicle 10 while forming a measured parameter value.
- the measuring device 100 measures the adhesion coefficient Fx between a rotating part and a rail of a rail section 20 on which the rail vehicle 10 travels as a parameter measured value.
- the rotary part can be, for example, the wheel identified by the reference number 11 in FIG. covered and not visible in FIG. 1).
- the measuring device 100 can thus also be referred to as an adhesion coefficient measuring device.
- the measuring device 100 includes a computing device 110 and a memory 120 in which a software module SPM is stored. When executed by the computing device 110 , the software module SPM determines the mode of operation of the measuring device 100 .
- the measuring device 100 When the software module SPM is actively operated by the computing device 110, the measuring device 100 preferably carries out a measuring method Mv, as is shown by way of example in the form of a block diagram in FIG. In the exemplary embodiment according to FIG. 2, it is assumed that the coefficient of adhesion Fx of the wheel 11 is measured, so that the subsequent measurement method Mv is wheel-related with regard to the mass inertia and the forces and torques taken into account.
- the measuring device 100 can also work in relation to the wheelset 12; in the latter case, the following measurement procedure Mv would have to be carried out with regard to the values for the mass inertia, forces and torques, but otherwise identical.
- a vehicle-side torque acting on the wheel 11 is determined with a computing module RM, forming a vehicle-side torque value M, which can change during the journey and thus depends on the time t and is always used
- the braking torque Mb and the driving torque Ma and their quantitative values can be made available, for example, by vehicle control device 200, as shown by way of example in FIG. 1; alternatively, these quantitative values can also be recorded and supplied by separate sensors, which are not shown in FIG.
- the computing module RM can then determine the change dN/dt in the speed N of the wheel 11 for the respective point in time t according to:
- Mx(t-Td) designates an adhesion torque value fed into the computing module RM, which describes the adhesion torque acting on the wheel 11 on the rail side and was determined at an earlier point in time t-Td (during the previous loop run through of the control loop RS).
- Td designates the delay time of the control loop RS and is symbolized in FIG. 2 by a delay block VZB.
- Mx(t-Td) was thus determined as the adhesion torque value at the end of the last loop run through of the control loop RS and is evaluated by the computing module RM at the current point in time t.
- the difference Ef(t) between a measured measured rotation value Ng(t), which indicates the actual rotational speed N of the wheel 11, and the estimated rotation value Nb(t) is then calculated within the control loop RS using a difference generator DB.
- the measured rotation value Ng can be made available by the vehicle control unit 200, as shown in FIG. 1 by way of example; alternatively, the measured rotation value Ng can also be supplied by a separate sensor, which is not shown in FIG.
- the difference Ef(t) is fed into a control device PID, for example a PID controller, whose behavior has reinforcing (P), integrating (I) and differentiating (D) properties.
- the control device PID On the output side, the control device PID generates a controller output value which is proportional to the slip-dependent friction between wheel and rail and forms a coefficient of adhesion Fx(t) or is at least proportional to it, for example according to: dEf(t) Kpid
- Kpid, Kv and Kn are preferably in the following ranges:
- the controller output value or the adhesion coefficient Fx(t) is then multiplied by the vertical force Q (or a quantitative vertical force Q) using a first multiplier MP1. tiv specifying value) and multiplied by a second multiplier MP2 with the radius R of the wheel 11.
- the vertical force Q is preferably calculated as a function of the driving situation and thus time by simulating the mass distribution in the rail vehicle 10, since the mass distribution can change depending on the driving situation (braking/accelerating/driving resistance) and thus the vertical force Q can change for each individual wheel; the mass distribution is preferably simulated in the computing module RM.
- the vertical force Q can also be regarded as constant and can be determined by dividing the total mass of the rail vehicle 10 by the total number of wheels.
- Mx ( t ) Q • R • Fx ( t ) which replaces the previous adhesion torque value Mx(t-Td) taken into account in the current loop of the control loop RS and for the next loop of the control loop RS instead of the old adhesion torque value Mx(t-Td) is used.
- the respective driving resistance Fw which supports the braking but counteracts the acceleration
- a speed value V indicating the driving speed of the rail vehicle 10--and thus include it with the correct sign when determining the torque value M on the vehicle is, for example according to:
- vehicle control device 200 adjusts or at least can adjust at least one travel and/or braking parameter as a function of measured adhesion coefficient Fx of measuring device 100 while driving.
- Such a change or adjustment to the measured adhesion coefficients Fx of measuring device 100 is particularly advantageous if the currently measured adhesion coefficients Fx deviate from the adhesion coefficients stored in vehicle control device 200, which were recorded during one or more previous journeys on the same route 20, and thus Better vehicle control can be expected on the basis of the currently measured adhesion coefficients Fx.
- the vehicle control device 200 modifies a braking parameter, preferably a control parameter BRP for a slip controller 211, depending on the measured adhesion coefficients Fx, which acts on the brake 212 assigned to the wheel 11 and controls its braking force.
- the brake 212 can be actuated by the vehicle control device 200 by means of a brake control signal BS, independently of an indirect influence by the control parameter BRP.
- the vehicle control device 200 specifies a maximum drive force, for example as the or one of the drive parameters, which is intended to act on the wheel 11; For example, the driving force can be reduced if the measured coefficient of adhesion is lower than expected.
- the vehicle control device 200 and/or the measuring device 100 can store the measured adhesion coefficients Fx as a function of the respective route point X of the route 20 traveled, ie in the form Fx(X(t)).
- Fx(X(t)) the measured adhesion coefficients
- two tere simulation - for example, with an external simulation device 300 as shown in Figure 3 - simulated the journey of the rail vehicle 10 on the same route 20 at a later point in time over time or. be post-simulated.
- the journey and/or braking parameters of the vehicle control device 200 can be optimized for future journeys on the same route 20 in order to best adapt the vehicle control to the actual route conditions.
- the measuring device 100 and its measuring method for measuring a parameter relevant to the travel of the rail vehicle 10 can also be used for other, for example all other wheels (driven or non-driven wheels) of the rail vehicle 10 in an identical or comparable form.
