A Control and Fault-Tolerant Strategy Based on Electromechanical Brake System

<div class="section abstract"><div class="htmlview paragraph">With the development of automotive electrification and intelligent technology, vehicles have higher and higher requirements for braking systems. On the one hand, it requires it to have an active braking function, and at the same time facilitates the integration with other control systems of the chassis domain. The system should minimize oil pollution as much as possible, and under the premise of ensuring the pedal force, it can be used to recover the brake energy as much as possible to improve the range of electric vehicles as possible. The new brake system based on Electronic mechanical brake (EMB) as a line -controlled decoupling braking system can not only meet the needs of the brake pedal sensation, but also achieve continuous and accurate control of braking power. It can effectively Taking into account braking economy, braking safety, and braking comfort. In addition, the development of EMB technology is still immature and the failure rate is high, so research on EMB's fault tolerance control research is very meaningful. This study mainly conducts research on electronic mechanical braking system control strategies. First of all, the EMB execution agency is selected, designed and calculated, and systematically models. Secondly, the EMB multi -stage closed -loop control strategy was designed based on the permanent magnet synchronous motor vector control method. Finally The design-based braking moment distribution strategy is designed, and the effectiveness of EMB control strategy and failure control is verified by Simulink simulation.</div></div>
