Abstract

A control unit for a rail vehicle, comprising a braking control unit that contains an electronic braking control device for emitting control commands to brake actuators and/or comprising an anti-skid device, which controls the wheel slip of the wheels of at least one axle in accordance with at least one rotational speed signal from an anti-skid sensor. The control unit also comprises a roll monitoring unit with an electronic roll monitoring control device and at least one roll monitoring sensor for detecting the rotational speed of at least some wheels in the form of a rotational speed signal, and comprises a rolling gear monitoring unit for monitoring and/or diagnosing critical conditions of and damage to the rolling gear. The monitoring unit comprises an electronic control device for monitoring the rolling gear. The electronic control device for monitoring the rolling gear and/or the electronic anti-skid control device and/or the electronic braking control device and/or the electronic roll monitoring control device are combined to form a structural unit.

Claims

1. A control device for a rail vehicle comprising:

a combination sensor that generates a rotational speed signal and at least one of a signal indicating a temperature of a wheel set bearing and an oscillation signal indicating oscillations occurring at the wheel set bearing,

a first device, wherein the first device is a rolling gear monitoring device that monitors critical states and damage of a rolling gear,

a second device, wherein the second device is an anti skid device which controls the wheel slip of the wheels of at least one axle as a function of the rotational speed signal supplied to an electronic anti-skid control unit by the combination sensor, and

a third device, wherein the third device is a roll monitoring device that senses disturbances in the rotation of wheels or the failure of wheels to rotate and including an electronic roll monitoring control unit which receives the rotational speed signal of the combination sensor,

wherein the first device, the second device and the third device are combined to form one structural unit,

wherein the rolling gear monitoring device evaluates the rotational speed signal of the combination sensor, and

wherein the first device, the second device and the third device have at least one of a common power supply and a common interface for communicating with an operator and a common interface for communicating with a vehicle control system.

2. The control device of claim 1, wherein the common interface for communicating with the vehicle control system is connected to a vehicle bus.

3. The control device of claim 2, further comprising a display device configured to signal critical states which the rolling gear monitoring device has detected.

4. A rail vehicle containing the control device of claim 1.
