Patent ID: 6848756

Claim:
Method of applying clamping forces in a brake system that is electrically operable by means of an actuator and includes a first friction lining and a brake disc, comprising the steps of: defining a static correlation between an actuating travel of said actuator or, an actuator position and an actual actuator clamping force, and determining a measured clamping force value by way of a clamping force sensor value and a position sensor value, wherein the static correlation is defined by a mathematical model having parameters determined during actuation of said actuator, wherein the static correlation is represented by an estimated actuator clamping force value calculated by using a polynomial of second order: F estimat =a 2 * 2 +a 1 *φ+a 0 , wherein a first derivative of the polynomial in relation to the actuator position is evaluated for detecting a brake application.
