Analysis of shifting control strategy for new plug-in hybrid electric bus
A new type of plug-in hybrid transmission was presented and its shifting mode was analyzed.Based on the AMESim simulation software,the simulation model of the new hybrid transmission was established,the shift control strategy was analyzed and formulated,the test case was designed,and the whole vehicle model was built in MATLAB/Simulink for simulation test.The simulation results showed that the new hybrid power device has good control effect on shift impact and good shift quality,and can realize smooth shift without power interruption and meet the requirements of control strategy.This study has important practical significance for improving the shift quality of urban new energy buses and energy saving and environmental protection.
