Abstract
A method and a device for determining at least one basic value of at least one measured quantity of a brake system. At the start of the system, the measured quantity prevailing at that time is then assumed as the basic value.
Claims15
A method for calibrating a brake system, comprising:
- predetermining a first threshold value;
- obtaining a zero state value of a measured quantity upon activation of the brake system;
- and
- establishing a calibrated value of the measured quantity as the zero state value if the zero state value is less then the first threshold value and if no pressure control signal is being output to a wheel brake actuator.

A method for calibrating a brake system of a vehicle, comprising:
- predetermining a first threshold value;
- obtaining a measured value of a measured quantity during operation of the vehicle;
- determining a calculated value of the measured quantity as a function of the measured value and a calibrated value;
- and
- establishing a new value for the calibrated value if the calculated value is less than the first threshold value and if no pressure control signal is being output to a wheel brake actuator.
