Research on High Voltage Driven Electromechanical Brake System

The Electromechanical Brake System (EMB) is a type of brake-by-wire system composed of a motor, reduction mechanism, and motion switching mechanism. EMB plays a significant role in promoting high-frequency wire-controlled chassis technology and high-level intelligent driving technology, and has received extensive attention from many domestic and foreign enterprises and research institutes. The braking response speed of existing EMBs is not as pronounced compared with that of the Electrohydraulic Brake System (EHB). Improving the braking response speed of EMBs is crucial for expanding their applications. This paper takes the EMB driven by a high-voltage motor as the research object, and focuses on improving the braking response speed of EMB. This paper completes the research work of EMB design, EMB control algorithm design, EMB simulation platform construction, EMB experimental platform construction and test verification. Simulation and test results show that the high-voltage motor-driven EMB has the ability to eliminate braking clearance within 20 ms and provide maximum braking force within 50 ms, significantly improving the braking response speed.
