The invention relates to the technical field of dual-motor hybrid vehicles, in particular to an engine shutdown control method and device of a dual-motor hybrid vehicle and the hybrid vehicle, and the method comprises the steps that the current shutdown stage of an engine is recognized; if the current shutdown stage is the first stage, the compression cylinder pressure of the engine is reduced; and if the current shutdown stage is a second stage, the crankshaft position of the engine is adjusted to the target position and then maintained for a first preset duration, and the second stage is located after the first stage. Therefore, the problems that abnormal sound is prone to occurring in the engine shutdown process of the dual-motor hybrid vehicle, and the user experience feeling is poor are solved.

    本申请涉及双电机混动车辆技术领域,特别涉及一种双电机混动车辆的发动机停机控制方法、装置及混动车辆,其中,方法包括:识别发动机的当前停机阶段;若当前停机阶段为第一阶段,则降低发动机的压缩缸压;若当前停机阶段为第二阶段,则将发动机的曲轴位置调整至目标位置后维持第一预设时长,其中,第二阶段位于第一阶段之后。由此,解决了双电机混动车辆在发动机停机过程中易出现异响,造成用户体验感较差等问题。
