摘　　要：针对混合动力乘用车的动力经济性问题,设计了双行星排式动力耦合系统。以燃油消耗量最小为优化目标,建立整车模型,对动力部件进行选型和参数匹配,采用基于转矩的逻辑门限控制策略,获取动力源最优转矩分配,建立AVL-Cruise和MATLAB/Simulink联合仿真环境,进行动力性和经济性仿真。仿真结果表明,NEDC工况下与原车相比,百公里燃油消耗量和零百公里加速时间分别下降了26.1%和7%,最高车速、最大爬坡度分别提高了19.5%和15.4%,整车的动力性与经济性均有明显改善。Aiming at improving the power efficiency of hybrid commercial vehicles,a dual-planetary gear power coupling system was designed.Taking the minimum fuel consumption as the optimization objective,the whole vehicle model was established,and the power components selection and parameters matching were conducted.The torque-based logic threshold control strategy was adopted to obtain the optimal torque distribution of the power source,and a joint simulation environment of AVL-Cruise and MATLAB/Simulink was established to carry out the simulation of power performance and energy economy.The simulation results show that,under the NEDC condition,compared with the original vehicle,the 100 km fuel consumption and 0 km/h to 100 km/h acceleration time decreased by 26.1%and 7%,respectively.While the maximum speed and maximum gradeability increased by 19.5%and 15.4%,respectively.Thus,the power and economical performance of the whole vehicle were significantly improved.
