- a blocked axle can be detected.
- the brake control device may be configured to close the presence of a locked axle and / or a locked wheel when no brake pressure or brake current is being applied, but a braking force is applied to a friction brake device. Because then it can be assumed that the friction brake is in a rubbing locking position, which permanently decelerates an axis or even can block.

For example, assume that a brake force sensor or a brake torque sensor generates a different signal for a locked wheel or a blocked axle than when an axle or a wheel is rotating. In the locked state, a sliding friction will act while rolling will cause rolling friction. This can be reflected in different signal forms and / or signal levels of a brake sensor device.
- the invention also relates to a brake system for a rail vehicle with a brake control device described herein.
- the brake system may in particular be a brake system with one or more adhesion-dependent braking devices, in particular pressure-actuated or electrically actuated braking devices.
- the pressure-actuated or electrically-actuated brake devices may each comprise one or more friction brake devices.
- the brake devices may comprise, for example, one or more sensor devices that are connected or connectable to the brake control device, such as a brake sensor device and / or a wheel speed sensor device and / or a brake actuation sensor device such as a brake pressure sensor device and / or a brake current sensor device. It is conceivable that the brake system has one or more friction brake devices.
- the brake control device is designed to control the friction brake devices of the brake system, for example by controlling an electropneumatic or electro-hydraulic main control valve device or an electrical power supply.
- the invention relates to a rail vehicle with a brake system described herein and / or a brake control device described herein.
- the invention also relates to a method for carrying out a functional diagnosis of a friction brake device of a brake system of a rail vehicle with at least one frictionally-dependent brake device, comprising transmitting brake data by at least one brake sensor device to a brake control device described herein, wherein the brake sensor device for detecting a by at least one Reibbrems adopted the The braking force exerted by the at least one friction brake device of the traction-dependent brake device is the receiving, by the brake control device, the brake data, and performing, by the brake control device, a functional diagnosis of at least one Reibbremseinrich- device based on the brake data.
- the brake control device may be one of the brake control devices described herein.
- the brake system may be one of the brake systems described herein.
- the method may include the activation of a test braking by the brake control device.
- the functional diagnosis may be performed based on actuation data transmitted from a brake actuation sensor direction. This actuation data can be received by the brake control device. It can be provided that the brake control device, based on the brake data on the presence of a locked wheel and / or a blocked axle closes.
- the brake control device may perform the functional diagnosis based on comparison data stored in a memory device and / or based on wheel speed data provided by one or more wheel speed sensors. Before or during the detection of the braking force and / or the braking torque, a test braking can be controlled by the brake control device.
- the functional diagnosis can in particular be carried out based on data transmitted during the test braking by the brake sensor device.
- the brake control device is for Functional diagnosis based on the braking data carried out in parallel and / or redundantly to a monitoring of a Radrotation or the determination of a blocking of a wheel or an axle by a Gleitschutzrechner and / or a Rollüberwachungsrechner.
- the functional diagnosis can generally give different results.
- the brake control device can recognize a blocked axle as a result of the functional diagnosis when the vehicle is moving so that a braking torque for the blocked axle or the blocked wheel emerges from the brake data without a brake pressure being present and / or a braking being activated. In this case, it can be compared, for example, whether a noteworthy braking force and / or a braking torque is applied to the other axles and / or wheels of the vehicle, which can be attributed to a brake pressure or braking current.
- a brake pressure or braking current is applied to the other wheels and / or a corresponding activation has been carried out, and in this way a braking force and / or a braking torque are effective, it is probable that the wheel in question will also be braked correctly, but at the brake pressure detection or brake current detection is an error.
- comparison with electronic or digital control may help determine whether a locked wheel or faulty brake pressure indicator or brake current indicator is present. Because it is unlikely that a faulty drive signal and a faulty brake pressure detection or brake current detection occur simultaneously. In addition, it can be determined as part of the function diagnosis whether the vehicle is moving.
- the signal of a brake sensor device in a non-moving vehicle differs from a signal that is caused when a braking torque applied, ie during a moving state. Because when the vehicle is not moving, although there is a braking force, but no braking torque is generated because the wheel and / or the axle is not rotating. In particular, when checking several wheels or axles, this can condition of the vehicle to be closed. Even with blocking wheels, the signals of the brake sensor device may differ from the signals at train stop.
- a braking torque and / or a braking force is present when the brake and vehicle are moved, ie when no brake pressure or braking current is applied to the at least one friction brake device or friction brake devices, it can be assumed that the brake is blocked or at least without corresponding request or Actuation is applied. If a brake pressure or brake current is provided when the vehicle is moving, but no braking torque is detected, there may be a malfunction of the brake in which a brake pressure or brake current is not converted into a braking force or a braking torque. If it is possible to conclude from a data of another sensor device, for example from wheel speed data, on a blocked axle or a blocked wheel, it can be assumed in this case that the axle blocks for reasons which are not in the brake system.
- the train operation can be performed in different ways. For example, when a stalled brake is detected with a train stopped, a single brake can be placed in a neutral position and disconnected from a pressure or power supply. If necessary, the train may then continue to travel at a slower speed by appropriately controlling the remaining friction brake devices and other brake systems.
- the described function diagnosis becomes a Roll monitoring possible, which may be formed separately from a sliding protection.
- a monitoring of the rolling properties of axles and / or wheels is possible, which can be carried out independently of wheel speed sensors.
- wheel speed sensors provide support data for the functional diagnosis described, in principle a blocked wheel and / or a blocked axle can take place independently of this support data.
- the described test braking acts as a dynamic brake test while driving.
- the brake control device may be configured to detect and / or identify periodic and / or quasi-periodic signals in the brake data.
- the brake control device may be designed to store detected periodic and / or quasi-periodic signals or to store data based on such signals.
- the brake control device is able to compare stored data with current brake data. Based on the comparison, for example, the elimination of a periodic signal in a Reibbrems worn and / or the shifting of the period can be determined towards larger periodicities. This may be an indication of a blocked or sliding wheel. It may be expedient that the brake control device is designed to determine a signal spectrum in the frequency range from the braking data, for example by a suitable transformation like a Fourier transform. It may also be appropriate to normalize the data appropriately, such as by using wheel speed data for normalization and / or filtering of the brake data. A normal period may be defined for periodic signals as the basis of comparison which is independent of the current wheel speed.
