摘要
以并联式混合动力车辆为研究对象,基于MATLAB/Simulink软件,建立了发动机、电动机、蓄电池以及整车仿真模型,制定了整车控制策略.仿真结果表明,应用该策略对发动机与电机间的功率输出进行协调控制,能明显提高整车燃油经济性,并能够维持SOC在规定的工作区间变化.
Based on the software MATLAB/Simulink, taking a parallel hybrid electric vehicle as research object, the models of engine, motor, battery and whole vehicle are established. The systematic control strategy is also developed. The simulation results indicate that, the application of the strategy to coordinate and control the output power between engine and motor, can improve the fuel economy significandy, while, the SOC is maintained in an appropriate range.
