Abstract :
A novel brake-by-wire system based on direct-drive electro-hydraulic unit, which regulates braking force flexibly and dependently, was designed for electric vehicles to improve braking performance and recovery efficiency. The structure of brake unit is discussed in detail as well as the composition of brake system. Since this novel system is well to coordinate with regenerative system because of flexibly controlled friction force, the regenerative strategy is discussed in detail. At last, a electric vehicle model based on Matlab/Simulink and AMESim is established to verify that this novel system is able to control friction force flexibly according to motor status and the regenerative efficiency is significantly improved.
