A Gap Control Method for Electromechanical Brakes

doi:10.12382/bgxb.2021.0395

Abstract

Abstract: A novel electromechanical brakes (EMB) design is proposed to address current problems in gap control, such as greater size due to the integration of additional mechanical structures and sensors for automatic adjustment, complex structures, and increased costs. A gap control strategy is proposed to use motor speed and current change signals to identify the critical points of contact and separation between the brake pad and brake disc. Furthermore, a mathematical model is established. The designed EMB brake is simulated and analyzed using MATLAB/Simulink. Based on the pressure loop, speed loop, and current loop, the EMB adopts PID type-Ⅲ control loop as the control system. Simulation and experimental results demonstrate that the EMB and gap control strategy can effectively ensure the brake gap and reduce the target clamping force as well as the time required to eliminate the brake gap, validating the feasibility and effect of the design.
