The present master thesis focuses on the study of brake lining wear calculation. This brake system regulation function is worldwide only provided in passenger cars of the BMW Group. It calculates continually the wear of brake linings and displays to the driver the kilometre availability, as part of the Conditioned Based Service.The task assignment consists in the analysis and improvement of the current brake lining wear monitoring function that is used by BMW. First of all, the preliminary required task would be to understand and analyse the current status of the brake lining wear calculation. For that purpose, it will be necessary to build up a simulation environment, in which the calculation algorithm could be tested. The virtual calculation results can be compared with available experimental data from brake test bench and vehicle tests. Furthermore, in order to understand wear process, a study of all possible influence variables on the brake lining wear will be required. The conclusion of this analysis will serve to design an experimental planning to test brake linings. Then, a method has to be developed to find out possible empirical equations of wear that fit the characteristic diagram obtained on the brake test bench. Finally, the models obtained must be tested and validated with real test bench wear measurements.
