Aiming at the problems of high energy consumption and low energy recovery of braking system of new energy electric vehicle,an electrohydraulic composite braking system was designed.Based on the idea of parallel control strategy,a matching control strategy of braking system was proposed.The whole vehicle model was built in Carsim,the braking system and control strategy model were built in MATLAB/Simulink,and then the joint simulation model was built,and the simulations were carried out under NEDC cycle and the emergency braking condition respectively.The simulation results show that the designed electrohydraulic braking system of the new energy electric vehicle can work well,the control strategy of the braking system meets the requirements,and the energy recovery rate is high.
