针对一款新设计的基于金属带式无级自动变速器(CVT)的插电式混合动力轿车(PHEV)的特点，依照整车不同电量状态和功率需求，提出了一种多阶段多目标的能量管理策略。控制电机输出扭矩，以调整发动机工作点；控制CVT比，以优化电机工作点。在Matlab/Simulink平台下，用前向仿真方法，搭建整车模型；在新欧洲行驶循环(NEDC)工况下，进行仿真。结果表明：在不同工况下，该能量管理策略，满足了整车的控制需求，合理地分配了电机扭矩和发动机扭矩；等效油耗为4.26 L/(100 km)，比常规汽油车节能46.1%。因而，验证了该能量管理策略的有效性。

A multi-stage and multi-objective energy management strategy was proposed based on metal V-belt continuously variable transmission (CVT) in the light of the characteristics of a new designed plug-in hybrid electric vehicle (PHEV) according to the different states of charge and required power. Adjustment of an engine’s working point was made by control ing the motor’s output torque;And optimization of a motor’s working point was promoted by control ing CVT ratio. A PHEV model was established by using forward-facing simulation on a Matlab/Simulink platform, and the simulations were conducted under NEDC (New European Drive Cycle) conditions. The results show that under different conditions, the energy management strategy satisifes the PHEV control requirements;and distributes reasonably the motor torque and the internal combustion engine torque;The equivalent fuel consumption of 4.26 L/(100 km) for the new strategy is 46.1%lower than that for the conventional internal combustion engine vehicle. Therefore, the availability is checked for the energy management strategy.
