Regenerative braking study for a hydraulic hybrid vehicle

One of the most advantages of hybrid vehicles is that the wasted braking energy can be captured and reused during driving cycle. In this paper, a regenerative braking system for hydraulic hybrid vehicles is investigated. Based on Matlab/Simulink, the model of proposed system is established. The influences of components parameters to the performance of braking system, the rate of recovery energy and the efficiencies of the system are analysed and calculated from data that obtained via simulation. The simulation results indicate that even thought the percent of stored energy and the rate of energy recovery of the system are varied and depended on many factors, the total efficiency is reasonable and high potential to implement in the real vehicle. The architecture of the proposed system is the prototype of experimental system in our future research.
