The invention discloses a hybrid electric vehicle and a power control mode decision-making method and device. The hybrid electric vehicle is a parallel hybrid electric vehicle, and the decision-making method comprises the following steps of obtaining a target power control mode of the hybrid electric vehicle according to a whole vehicle mode and a whole vehicle wheel end demand torque grade; judging whether the target power control mode is the same as a current power control mode of the hybrid electric vehicle; if the target power control mode is different from the current power control mode, obtaining mode switching information, and switching the power control mode of the hybrid electric vehicle to the target power control mode from the current power control mode according to the mode switching information. The decision-making method can be applied to hybrid electric vehicles with different power system structures to realize switching of power control modes, so that the pre-research period can be greatly shortened, the research and development energy can be saved, and the research and development cost of multi-structure vehicle types can be reduced.
本发明公开了一种混合动力汽车及其动力控制模式的决策方法、装置,其中,混合动力汽车为并联式混合动力汽车,决策方法包括以下步骤:根据整车模式和整车轮端需求扭矩等级获取混合动力汽车的目标动力控制模式;判断目标动力控制模式与混合动力汽车的当前动力控制模式是否相同;如果目标动力控制模式与当前动力控制模式不同,则获取模式切换信息,并根据模式切换信息,将混合动力汽车的动力控制模式从当前动力控制模式切换至目标动力控制模式。该决策方法能够运用于不同动力系统结构的混合动力汽车,以实现动力控制模式的切换,从而能够大大缩短预研周期,节省研发精力,降低多结构车型的研发成本。
