并联式混合动力汽车整车控制策略研究

Study on Control Strategy of Parallel Hybrid Electric Vehicle

针对所提出的并联式混合动力汽车构型,设计了一种基于整车稳态模式和瞬态模式的实时控制策略,主要分为怠速充电控制、发动机启动控制、离合器转速同步控制、动力模式控制和能量回收控制五个方面。在保证动力性和经济性的前提下,尽可能地保证行驶平顺性和响应速度。最后,进行实车测试验证,测试结果表明所提策略在不同工况下均有较好表现,进一步说明了所提策略的可行性和有效性。

Aiming at the proposed parallel hybrid vehicle configuration,a real-time control strategy based on the steady-state mode and transient mode of the vehicle was designed.It is mainly divided into five aspects:idle charge control,engine start control,clutch speed synchronization control,power mode control and energy recovery control.On the premise of ensuring power and economy,as far as possible to ensure driving smoothness and response speed.Finally,a real vehicle test was performed.The test results show that the proposed strategy performs well under different working conditions,further illustrating the feasibility and effectiveness of the proposed strategy.
