The invention belongs to the technical field of engines and particularly relates to a control method for cylinder cutout mode switching. The control method for cylinder cutout mode switching comprisesthe steps of detecting whether a cylinder cutout demand exists or not, determining the engine to continue operating in the current mode when no cylinder cutout demand exists, determining the engine to switch the current mode to another operation mode when the cylinder cutout demand exists, judging whether the switching moment is an initial point of a period or not, and controlling the engine to conduct mode switching when the switching moment is the initial point of the period. According to the control method for cylinder cutout mode switching, by detecting whether the cylinder cutout demandexists or not, the engine is controlled to conduct switching between a normal mode, a cylinder cutout mode and a different cylinder cutout mode, the switching moment is controlled, mode switching is conducted at the initial po
