The present study focuses on the analysis of the haptic brake pedal developed hydraulic brake system numerical model behavior varying its operative parameters: nominal conditions, increase of air content in brake fluid and brake pads wear are simulated and compared. To carry out the analysis, an experimental setup based on EtherCAT® network and admittance control loop has been implemented, together with a refinement of the numerical model in order to test plausible passenger car and race car systems. The results show about twice brake pedal angle travel for passenger car layout with respect to the race counterpart. Moreover, the different tested conditions physics captured by the numerical model is reflected in the correspondent pedal angle travels and in the haptic feedback to the user.

Abstract

The present study focuses on the analysis of the haptic brake pedal developed hydraulic brake system numerical model behavior varying its operative parameters: nominal conditions, increase of air content in brake fluid and brake pads wear are simulated and compared. To carry out the analysis, an experimental setup based on EtherCAT® network and admittance control loop has been implemented, together with a refinement of the numerical model in order to test plausible passenger car and race car systems. The results show about twice brake pedal angle travel for passenger car layout with respect to the race counterpart. Moreover, the different tested conditions physics captured by the numerical model is reflected in the correspondent pedal angle travels and in the haptic feedback to the user.
