Abstract:
The present invention discloses a method for brake pressure adjustment of a wheel brake comprising the following steps: determining a preliminary nominal pressure gradient in a brake control, determining actuating signals for a hydraulic pump and/or at least one hydraulic valve for the adjustment of the nominal pressure gradient, determining the actual pressure by way of a pressure model, determining the slip of a driven wheel, comparing the actual pressure with a first threshold value that is lower than the maximum possible brake pressure, and comparing the wheel slip, if the wheel slip is a traction slip, with a second threshold value, wherein, if the actual pressure and the wheel slip exceed the respective threshold values, the preliminary nominal pressure gradient is raised. The present invention also relates to a corresponding device.
