  • Patent number: 11787374
    Abstract: 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.

  • Patent number: 11485337
    Abstract: 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.

  • Publication number: 20190359189
    Abstract: The invention relates to a method for maintaining total braking power of a rail vehicle while taking the available friction conditions into consideration. The method includes recognizing that at least one unit is wheel-slide controlled; retrieving the type of friction prevailing on the wheel-slide controlled units; determining the values ?0 and K?0 for each unit that is wheel-slide controlled; forming a function for the value ?0 and a function for the value K?0, in each case over the entire length of the units comparing the actual braking request in each of the units, to the function of the value K?0, and changing each braking request in each of the units, towards the respective value of the function of K?0.

  • Patent number: 9126605
    Abstract: A control device for a brake system of a rail vehicle, the brake system having at least one first brake device and a second brake device, which devices can be actuated by an actuating force during a braking process. The first brake device and the second brake device are adhesion-type brake devices. The control device is capable of receiving and/or generating a loss of adhesion signal, which identifies insufficient adhesion for the first and/or second brake device, and is also designed, during a braking process, to actuate the first and/or second brake device with an increased actuating force if a loss of adhesion signal is present. Also disclosed is a brake system for a rail vehicle having a control device of this type, a corresponding rail vehicle and a method for controlling the brake system of a rail vehicle using a control device.

  • Patent number: 8844573
    Abstract: 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.

  • Patent number: 8577546
    Abstract: 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.
