Patent number: 11787374Abstract: 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.Type: GrantFiled: December 12, 2017Date of Patent: October 17, 2023Inventors: Thomas Rasel, Ulf Friesen, Marc-Oliver Herden, Jörg-Johannes Wach, Reinhold Mayer

Publication number: 20190359189Abstract: 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.Type: ApplicationFiled: December 12, 2017Publication date: November 28, 2019Inventors: Thomas RASEL, Ulf FRIESEN, Christoph TOMBERGER, Jörg-Johannes WACH, Reinhold MAYER
