摘 要:
针对一种采用金属带式无级变速器（CVT）的并联式混合动力汽车（PHEV），以发动机稳态效率图和电池的充放电内阻曲线为依据，提出基于逻辑门限方法的PHEV能量管理策略，实现混合动力系统不同工作模式间的动态切换。并通过确定不同工作模式中混合动力系统的最佳工作曲线，合理控制发动机和电动机的转矩分配以及CVT的速比。基于ADVISOR仿真平台的仿真研究表明，所提出的能量管理策略能够在满足车辆动力性能指标的前提下有效地降低混合动力汽车的燃油消耗，并能将电池组电池荷电状态（SOC）维持在合理的范围内。[著者文摘]

Abstract:
Based on the engine efficiency map and battery internal resistance curve, an energy management strategy is proposed for a parallel hybrid electric vehicle （PHEV） with metal v-belt continuously variable transmission （CVT） by using logic threshold approach to control the dynamical transitions between the various operation modes. The torque distribution between engine and motor, and CVT ratio are regulated through predetermined optimal operation lines of hybrid powertrain system in different operations. The simulation results in ADVISOR demonstrate that the energy management strategy can satisfy vehicle dynamic performance and reduce fuel consumption effectively, as well as keep battery state of charge （SOC） in reasonable range.[著者文摘]
