A method for improving the adhesion of a rail vehicle by conditioning selected axle(s), detects whether a higher total brake force can be achieved by changing the manipulated variable of the wheel slip at at least one unit from a current starting wheel slip to a forced wheel slip, and, if so, changes the wheel slip at at least one unit from the current starting wheel slip to the forced wheel slip by regulating the manipulated variable of the brake application force at the unit, whereby the friction ratios between the wheel and the rail changes at the subsequent units, and regulates the manipulated variable of the brake application force at the subsequent units to regulate the wheel slip, which is likewise changed by the changed friction ratios, at the units back to the unchanged manipulated variable of the starting wheel slip, optimized brake forces being produced at the units.

A method and a control device determine a position-related braking ability of a vehicle. A first vehicle determines at least one piece of position-related information of a route section, the at least one piece of position-related information of the route section being information relating to the braking ability on the route section. The first vehicle transmits the at least one piece of position-related information to a receiver, the receiver being at least one second vehicle, whereby the braking curves of at least one rail vehicle are adapted according to the situation, thus allowing safety on the route section and the utilization of the section to be improved.

A valve arrangement controls brake devices and auxiliary devices of a pneumatic brake system of a vehicle, and includes pneumatic control valves which are detachably arranged on at least one common support module containing compressed air channels, for carrying out braking functions or auxiliary braking functions of the brake system. The valve arrangement also includes several adjacently arranged block-shaped support modules having at least the same height and depth measurements and including channel sections forming common longitudinal channels when all of the support modules are adjacently arranged in a row. At least one unit hole receives a control valve embodied as a cartridge valve and arranged on a front side of each support module to enable switching the compressed air flow between inner channels.

A method for monitoring the driving behavior of a railway vehicle, wherein at least one measurement variable characterizing the vibrational behavior of at least one wheel set of the railway vehicle, is captured by at least one sensor providing a corresponding measurement signal. The method includes the steps of identifying at least one significant event or a combination of multiple significant events within the time trace of the measurement signal and identifying the event time at which the significant event took place, deriving the frequency from the time trace of the measurement signal starting from the event time, comparing the derived frequency to at least one stored reference frequency, evaluating the vibrational behavior of the wheel set as a function of the deviation of the derived frequency from the at least one stored reference frequency.

Method and device for monitoring the driving behavior of a railway vehicle

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.
