Design of control strategy for single-shaft parallel hybrid electric bus based on actual driving cycle

摘要

Based on the amount of data, the driving cycle is constructed by V-A analysis. The error between the developed driving cycle and sampling data shows that the developed cycle can truly reflect the actual operation status of Xi'an city bus. Based on the developed driving cycle and the parameters of single-shaft parallel hybrid electric bus, a simple logic threshold control strategy is given, and the critical rotational speed of engine is analyzed. Simulation results show that the critical speed of the engine has a certain influence on the vehicle's economic performance under the established control strategy based on developed driving cycle.
