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.
