Abstract：In order to recycle braking energy in urban operation, reduce energy consumption and environment pollution, and improve comprehensive performance of vehicle, the parallel hydraulic brake energy recovery technology was used to match parameters calculating and propose a control strategy of fixed proportion of composite brake force distribution. The mathematical model of vehicle energy recovery and release process was established and simulated by AMESim, and the simulation analysis was conducted according to the secondary element displacement changes in the energy recovery process. The results show that when the brake strength demand is low, the vehicle braking and energy recovery control strategy is effective for saving energy. The secondary element displacement change has significant effect on the vehicle braking time. In the premise of safe braking, maximizing the use of braking energy recovery system is the most effective way to improve the energy recovery.
