Design and Optimization Analysis of Wheel Cylinder Pressure Fuzzy Control for EHB Wheel Motor
Electronic hydraulic braking(EHB)is the use of electronic control system to achieve the control function of hydraulic actuator parts,the hub motor installed in the rim,can control the stability of the vehicle in emergency conditions.The hub motor is selected as the driving system of the electro-hydraulic composite braking system,and the EHB cylinder pressure control mode combined with the high pressure accumulator and the hydraulic pump is set up.The feasibility test of the control strategy is completed by Simulink-AMESim simulation platform.The results show that the braking ride control strategy,and a PID correction method to compensate motor braking method is constructed.Compared with other methods,the proposed method can significantly reduce the impact after entering the electro-hydraulic braking handover,and thus efficiently enhance the braking ride comfort.
