并联混合动力汽车的双重能量管理策略研究

Study of Double Energy Management Strategy for Parallel Hybrid Electric Vehicles

针对某一并联式混合动力汽车,设计以逻辑能量管理策略为主、模糊能量管理策略为辅的双重能量管理策略,以实现混合动力系统不同工作模式间的动态切换。仿真分析表明,该能量管理策略在满足车辆动力性能指标的前提下能有效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维持在合理的范围内。

For a parallel hybrid vehicle（PHV）, a double energy management strategy（EMS）is designed for PHV to dynamically switch the various operation modes of the hybrid powertrain system, which the double EMS relies mainly on the logic EMS and takes the fuzzy EMS as the secondary. The simulation analysis shows that this double EMS can effectively reduce the PHV fuel consumption, and make the batteries SOC maintained in a reasonable range under the precondition of meeting the vehicle dynamic performance.
