The invention provides a method for controlling series-parallel mode switching of a vehicle. The method comprises steps of that a series-parallel mode switching signal is received, and a first rotating speed difference value between the rotating speed of an engine and the rotating speed of an input shaft of a speed change device; a first power generation torque of a generator is further obtained;a generator power generation torque is adjusted according to the first power generation torque of the generator; when the rotation speed of the engine reaches a target rotation speed range, a clutch between the engine and the speed change device is controlled to be combined. The method is advantaged in that in the series-parallel switching process, the rotating speed of the engine is adjusted to the target rotating speed range, then the clutch is combined, dragging feeling caused by inconsistency of the rotating speed of the engine and the rotating speed of the input shaft of the speed changedevice is improved to a certain extent, and smoothness of a vehicle in the series-parallel mode switching process is improved.

    本发明提供了一种车辆串联切换混联模式的控制方法,包括接收串联切换混联模式信号,并获取发动机转速与变速装置输入轴转速的第一转速差值;进而得到发电机第一发电扭矩;根据发电机第一发电扭矩调整发电机发电扭矩;使得发动机转速进行调整,并当其达到目标转速范围时,控制发动机与变速装置之间的离合器结合。由此,通过在串联切换混联的过程中,调整发动机转速至目标转速范围,再进行离合器的结合,在一定程度上改善了由于发动机转速与变速装置输入轴转速不一致而带来的拖滞感,提升了串联与混联模式切换过程中车辆的平顺性。
