Abstract
AbstractAiming at a series hydraulic hybrid vehicle, the mathematical model and Matlab/Simulink simulation model of the vehicle are established, and the energy management strategy based on rules is put forward. The simulation results show that the control strategy not only realizes four working modes of hydraulic hybrid vehicle, but also improves its fuel economy by 11.9%. It is found that the volume of accumulator and the working pressure range of accumulator are two important parameters that affect the fuel economy of hydraulic hybrid vehicle. Under the condition of a certain accumulator volume, increasing the working pressure range of the accumulator can not only increase the energy storage of the accumulator, but also reduce the idling times of the engine and further improve the fuel economy of the vehicle.
