The invention discloses a hybrid electric vehicle, a series-parallel connection driving mode switching method and device of the hybrid electric vehicle and a medium. The switching method comprises the steps that the current driving mode of the hybrid electric vehicle and driving force information under the current driving mode are obtained; judging whether the driving force information meets a switching condition corresponding to the current driving mode or not; if yes, the hybrid electric vehicle is controlled to be switched from the current driving mode to another driving mode different from the current driving mode. According to the technical scheme, whether the driving force information in the current driving mode meets the switching condition corresponding to the current driving mode or not is judged, and mode switching is carried out when the switching condition corresponding to the current driving mode is met, so that when larger driving force exists in another driving mode, driving mode switching is carried out in advance, and the driving efficiency is improved. The reduction amplitude of the whole vehicle driving force in the driving mode switching process is reduced, the continuity of the driving force is guaranteed, and the driving experience feeling is improved.

    本发明公开了一种混合动力汽车及其串并联驱动模式切换方法、装置和介质,该切换方法包括获取混合动力汽车当前的驱动模式,以及在当前的驱动模式下的驱动力信息;判断驱动力信息是否满足与当前的驱动模式对应的切换条件;若是,则控制混合动力汽车由当前的驱动模式切换至与当前的驱动模式不同的另一驱动模式。本发明的技术方案通过判断当前驱动模式下的驱动力信息是否满足当前的驱动模式对应的切换条件,并在满足当前的驱动模式对应的切换条件时,进行模式切换,从而在另一驱动模式下有更大驱动力时,提前进行驱动模式的切换,以减小驱动模式切换过程中的整车驱动力的降低幅度,保证驱动力的连续性,提升驾驶体验感。
