Control Strategy of Automatic Gear Shift for Hybrid Electric Machinery Vehicles
Automatic transmission control strategy is the key to measuring whether the vehicle can play its power,economy and driving ability after adopting automatic transmission technology.Therefore,it is the core technology of automatic mechanical transmission(AMT)and the research hotspot of automobile automatic transmission technology in China.Its main research contents include: optimal power shift control strategy and optimal energy consumption economy shift control strategy.In this paper,the AMT of a pure electric bus is taken as the research background,with the help of ATLAB/SIMULINK software,the simulation modeling method is used to improve the optimal power shift control strategy algorithm of the existing electric bus,and a more precise shift surface is obtained.Aiming at the optimal motor efficiency,a two-parameter shift control strategy is proposed based on the existing two-parameter shift control strategy.Three-parameter optimal economic shift control strategy and the optimal shift surface are obtained by simulation modeling algorithm.In order to comprehensively consider the dynamic and economic requirements of driving vehicles,a control scheme of automatic switching between dynamic shift and economic shift mode is formulated,and the above-mentioned shift strategy is implemented.The feasibility and superiority of these methods are verified by experiments.
