Abstract: A method for determining a pressure-volume characteristic curve of a brake caliper device is disclosed. The pressure-volume characteristic curve is formed from a number of pressure-volume data pairs, wherein in each pressure-volume data pair a pressure interpolation value is assigned to a volume interpolation value. The aim is to provide a method for the automated determination of the pressure-volume characteristic curve which can reduce inaccuracies of the pressure-volume characteristic curve because of wear and manufacturing tolerances of the brake caliper device. This is achieved by the volume interpolation value being determined by utilizing a compensation calculation on a number of auxiliary pressure-volume data pairs.
