The invention belongs to the field of hybrid vehicles, and discloses a gear switching method of a hybrid system and a control device of the hybrid system. The gear switching method of the hybrid power system comprises the following steps that after a vehicle is started, the working mode of the hybrid power system is determined; when the hybrid power system is in the direct drive mode, the target gear and the current gear of the vehicle are obtained, and the forward and reverse gear state of the vehicle is determined; determining target input parameters of an input shaft of the reduction gearbox according to the in-gear and out-gear states of the vehicle; controlling a generator to adjust an input parameter of an input shaft of the reduction gearbox to the target input parameter according to the target input parameter; and the reduction gearbox is controlled to conduct gear shifting action, and the gear is shifted to the target gear. According to the gear shifting method of the hybrid power system, the generator controls the input parameters of the input shaft of the reduction gearbox, so that the input and the output of the reduction gearbox can be matched with each other before gear shifting, the gear can be pushed directly during gear shifting, and gear shifting is smoother.

    本发明属于混动汽车领域,公开了一种混动系统的档位切换方法及其控制装置。混动系统的档位切换方法包括以下方法:在车辆启动后,确定混动系统的工作模式;在混动系统处于直驱模式时,获取车辆的目标档位和当前档位,确定车辆的进摘档状态;根据车辆的进摘档状态,确定减速箱的输入轴的目标输入参数;根据目标输入参数,控制发电机调整减速箱的输入轴的输入参数至目标输入参数;控制减速箱进行换档动作,换档至目标档位。本发明提供一种混动系统的档位切换方法,发电机对减速箱的输入轴进行输入参数的控制,使得减速箱在换档前输入和输出能够相互匹配,在换档时直接推档即可,换档更加平顺。
