algorithm is verified by test bench experiment. Test result shows that in the condition of active pressurize, use the method of modulating high frequency signal and duty ratio to coordinate regenerate braking force and hydraulic braking force. The requirement of target pressure and target pressurize rate during RBS pressurization can be satisfied. During RBS regenerate braking force is increasing, utilize low frequency control signal to control the working time of hydraulic pump and outlet valve. Then the hydraulic braking force decreases step by step. The requirement of braking is satisfied.
Key words: regenerative braking system; high frequency and low frequency pressure control; ESP hydraulic control unit
