Abstract: Aiming at the problem of the energy recovery efficiency and braking safety of the hydraulic regenerative braking system, the parameters matching of hydraulic regenerative braking system was studied. The hydraulic braking energy recovery system test bench was established, and the experiments were studied; Not only the test platform mathematical model of the hydraulic regenerative braking system was established, but the simulation model based on Matlab / Simulink was established. So the experiment of the energy recovery efficiency was studied. In order to study on the hydraulic braking energy recovery system for vehicle, a certain vehicle was established using ADAMS / car and Matlab. Firstly, the single factor on the energy recovery efficiency and braking safety effect was studied. Secondly, using the orthogonal experimental method, influence factors of energy recovery and braking safety were studied. The experiment results indicate that reasonable hydraulic brake energy recovery system parameters can significantly improve the efficiency of energy recovery and braking safety.
