The invention provides a gear shifting control method, device and system of a hybrid vehicle, the vehicle and a storage medium, and belongs to the technical field of vehicle control, and the method comprises the steps that under the condition that the vehicle is switched from a pure electric four-wheel drive mode to a pure electric rear drive mode, the torque of a front drive motor is controlled to be reduced, so that the torque of the front drive motor meets the synchronizer gear taking-off condition; under the condition that the torque of the front drive motor meets the synchronizer off-gear condition, the synchronizer is controlled to be subjected to off-gear; and controlling the rotating speed of the front-drive motor to be lower than the target rotating speed under the condition that the synchronizer succeeds in gear disengagement, so that the clutch meets the rapid closing condition. According to the embodiment of the invention, after the vehicle is switched from the pure electric four-wheel drive mode to the pure electric rear-wheel drive mode and needs to be immediately switched to the series connection mode, the clutch can be controlled to be rapidly closed, and then the engine is rapidly started, so that the process of starting the engine after the pure electric four-wheel drive mode is switched to the pure electric rear-wheel drive mode is more coherent and rapid.
本申请提供了一种混动车辆的换挡控制方法、装置、系统、车辆和存储介质,属于车辆控制技术领域,方法包括:在车辆从纯电四驱模式切换至纯电后驱模式的情况下,控制前驱电机的扭矩降低,以使前驱电机的扭矩满足同步器摘挡条件;在前驱电机的扭矩满足同步器摘挡条件的情况下,控制同步器摘挡;在同步器摘挡成功的情况下,控制前驱电机的转速低于目标转速,以使离合器满足快速闭合条件。本申请实施例能够在车辆从纯电四驱模式切换至纯电后驱模式后,需要立即切换到串联模式时,能够控制离合器快速闭合,进而快速启动发动机,使得纯电四驱模式切换纯电后驱模式后再启动发动机过程更连贯快捷。
