A New Brake-by-wire System based on Direct-drive Electro-hydraulic Brake Unit

摘要

A new brake-by-wire system based on direct-drive electro-hydraulic brake unit for flexibly modulating brake force is designed to improve braking performance and ride comfort. The structure of the brake unit and the composition of the system are discussed in detail. The simulation and experiment are completed to verify the brake unit is fast responsible and reliable after studying the unit model. At last, a vehicle model based on Matlab/Simulink and AMESim is established to verify that this new system is of fast response and is able to control brake force on every wheel independently and continuously.
