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.

Abstract: A method for operating a brake system, which comprises hydraulically actuatable wheel brakes with brake linings; a brake fluid reservoir; a master brake cylinder; a pressure supply device with a pressure piston that can be moved into a pressure chamber; an integrated parking brake, wherein, in a normal operating mode, brake pressure is actively built up in the wheel brakes by means of the pressure supply device, and wherein, in a parking operating mode, the integrated applies the brake linings of at least two wheel brakes, and wherein, when the integrated parking brake is released, the application of the linings is withdrawn again, wherein after the integrated parking brake has been released, the brake fluid volume displaced by the integrated parking brake is taken into consideration for the subsequent operation in the normal operating mode.

Abstract: A method for operating a brake system assembly includes evaluating input data and downgrading from a first mode to a second mode according to the result of the evaluation. The input data is a performance curve of the first mode and determining the performance curve includes using a torque-speed curve, a first mode-dependent characteristic curve with at least one mathematical formula. Evaluating the input data includes comparing an ascertained performance capability of the first mode according to the calculated performance characteristic with the performance capability of the second mode.
