A scheme of power split hydraulic hybrid transmission based on the input split type hydro-mechanical transmission has been provided.By analysis of the components
the configuration and the working principle of the hybrid powertrain
the feasible scheme was put forward.According to the computer and the running condition of the city
the characteristics of regenerative braking and auxiliary driving are analyzed.On the basis of the simulation results
it has been verified that the hydraulic hybrid technology improve the economy and the dynamic performance of the vehicle with HMT.The research is of engineering application value.
