Topology and Analysis of An Electromechanical Brake for Electric Vehicles

摘要

A new automotive electromechanical brake (EMB) is proposed in this study, which consists of the electromagnetic linear actuator that includes the stator and the mover, the power rod, the wedge, the braking pads, the caliper and the mechanical accessory. The braking torque is controlled via the actuator control unit. The topology structure of the proposed EMB is discussed. The models of the proposed EMB are developed, it is confirmed that the proposed EMB provides two braking forces with same magnitude and opposite direction to the braking pads, and the gains of the components and the proposed EMB are formulated. Furthermore, the effects of the geometrical parameter and the design parameter on the performance of the proposed EMB are analyzed via simulation. This study provides a novel EMB topology for electric vehicles, which possesses the faster dynamic response than previous EMBs.
