针对混合动力电动汽车工作模式的多样性带来模式之间切换及协调控制等问题,研究了混合动力电动汽车动力切换及协调控制技术,分析了混合动力电动汽车动力切换协调控制问题的产生机理,从发动机转矩参数实时获取、建模工具、控制策略、试验方法等方面分析了国内外有关混合动力电动汽车动力切换协调控制技术的研究现状,研究了动力切换协调控制的具体控制方法,提出了今后需要研究的关键技术:能够反映并联混合动力电动汽车动力切换瞬态特性的整车动力学建模;基于模型预测的电动机转矩补偿控制技术;动力切换及协调控制的试验研究;动力切换时的瞬态稳定性分析方法.
The power-switch and coordinated control issues of hybrid electric vehicle （HEV） become increasingly important because the HEV has diversity driving and braking modes. In order to investigate power-switch coordinated control technology, a brief description of coordinated control problems was given. Based on engine torque estimation, modeling tool, control strategy and testing method, the coordinated control problems were analyzed, and the relevant limitations were also discussed. The key technologies about coordinated control problems were proposed. The model was established to reflect the transient characteristics of parallel hybrid electric vehicle power switching. The control strategy was proposed based on motor torque compensation, experimental study and transient stability analysis.
