摘要:Brake-by-wire(BBW) system plays an important role in the implementation of active safety technology, auxiliary driving technology and unmanned driving technology. It can not only achieve energy recovery, but also effectively reduce the braking distance and improve the safety of vehicles. In this paper, a new electric booster(E-booster) hydraulic brake system is presented. The booster pedal is completely decoupled and the hydraulic pressure can be controlled linearly. The research contents of this paper are as follows: First, E-booster hydraulic brake system was established in AMESim software with high precision. It mainly includes worm gear and worm transmission mechanism module, brake main cylinder module, brake wheel cylinder module. PMSM model is established in simulink. Second, dual closed-loop PID Controller is designed in simulink to control hydraulic pressure and PMSM adopts vector control. Finally,effectiveness of the controller is verified based on Matlab/Simulink and AMESim software combination and simulation.
