Method for monitoring the thickness of the brake linings of a vehicle braking system
First Claim
1. A method for monitoring a thickness of at least one friction partner of a vehicle friction brake corresponding to a brake lining of a vehicle braking system, comprising the steps of:
- taking into account, in a wear model, an actuating time, an applied braking pressure, a relative speed between the brake lining and a moving brake element, and a prevailing temperature in a region of the brake lining in such a manner that a wear determined by the wear model is subtracted from a starting thickness of the brake lining;
individually monitoring each wheel of the vehicle; and
forming the wear model by a polynomial statement including at least the following factors;

Abstract
A method for monitoring the thickness of at least one friction partner of a vehicle friction brake, especially the brake linings of a vehicle braking system; for each braking action, the actuating time, the applied braking pressure, the relative speed between the brake lining and the moving brake element, as well as the prevailing temperature in this region, being taken into account in a wear model in such a manner, that the wear determined by the wear model is subtracted from a starting thickness of the friction partners, in particular, the brake linings, and each wheel of the vehicle being monitored individually. A preferred polynomial formulation is specified for the wear model. In the brake lining, at least one wear stamp can also be provided, upon reaching which the current, existing brake lining thickness and/or the polynomial formulation may be appropriately corrected.
