The invention relates to a power switching method, a power switching device and a hybrid vehicle. The power switching method comprises the steps that a vehicle control module responds to a first switching instruction and controls a generator and a clutch to be initialized; the current crankshaft torque is controlled to be increased to the first crankshaft torque, and clutch rotating speed closed-loop control is completed; second crankshaft torque required for switching the parallel mode and target electrical parameters of a clutch control module are analyzed, the current torque of an engine and the current torque of a generator are adjusted based on the second crankshaft torque, and the target electrical parameters are used for adjusting and controlling the current pressure of a clutch; wherein the second crankshaft torque is greater than the first crankshaft torque; and in response to the fact that the generator, the engine and the clutch meet the preset completion condition, it is judged that torque power switching is completed. By adopting the method, the power switching process can be optimized, the torque switching efficiency of the whole vehicle can be improved, the time for switching to the parallel mode can be shortened, and the timeliness of power response can be improved.

    本申请涉及一种动力切换方法、动力切换装置以及混合动力车辆。动力切换方法包括:车辆控制模块响应于获取第一切换指令,控制发电机以及离合器进行初始化;控制曲轴当前扭矩提升至第一曲轴扭矩以及完成离合器转速闭环控制;解析完成切换并联模式需求的第二曲轴扭矩以及离合器控制模块的目标电参数,基于第二曲轴扭矩调节发动机当前扭矩以及发电机当前扭矩,目标电参数用于调控离合器当前压力;其中,第二曲轴扭矩大于第一曲轴扭矩;响应于发电机、发动机以及离合器符合预设完成条件,判定完成扭矩动力切换。采用本方法能够优化动力切换过程,提高整车扭矩切换效率,有利于缩短切换至并联模式的时间,提高动力响应的及时性。
