The invention discloses a control method and a control device for switching series-parallel connection driving modes of a hybrid electric vehicle. The method comprises the following steps that the target required power of the hybrid electric vehicle and the available driving power of the hybrid electric vehicle in the pull-in stage of a clutch are obtained; judging whether the target demand power and the available driving power meet a preset condition or not; and under the condition that the target demand power and the available driving power meet preset conditions, the current working state of the hybrid electric vehicle is obtained, a control strategy set is generated based on the current working state, and the control strategy set is used for controlling whether the hybrid electric vehicle is switched from the series driving mode to the parallel driving mode or not. The technical problem that the available driving power of the driving motor is insufficient when the series mode and the parallel mode are switched in the prior art is solved.

    本发明公开了一种混合动力汽车串并联驱动模式切换的控制方法及控制装置。其中,该方法包括以下步骤:获取混合动力汽车的目标需求功率,以及在离合器的吸合阶段,混合动力汽车的可用驱动功率;判断目标需求功率与可用驱动功率是否满足预设条件;在目标需求功率与可用驱动功率满足预设条件的情况下,获取混合动力汽车的当前工作状态,基于当前工作状态,生成控制策略集,其中,控制策略集用于控制混合动力汽车是否由串联驱动模式切换至并联驱动模式。本发明解决了相关技术的串联模式与并联模式切换时存在的驱动电机可用驱动功率不足的技术问题。
