The invention provides a hybrid vehicle gear shifting control method, device and system, a vehicle and a storage medium, and belongs to the technical field of vehicle control, the method comprises the steps that under the condition that the vehicle is in a direct drive mode and a gear shifting request for a target gear is in an activated state, the torque of a front drive motor is controlled to be reduced to target torque, and a synchronizer is controlled to disengage the gear; controlling the rotating speed of the front-drive motor to be reduced to the target rotating speed under the condition that the synchronizer is successfully shifted; and under the condition that it is determined that the torque of the front-drive motor and the rotating speed of the front-drive motor meet the synchronizer gear engaging condition, the synchronizer is controlled to be engaged into the target gear. According to the embodiment of the invention, the torque of the front-drive motor is actively controlled to be reduced to the target torque, so that the synchronizer can be quickly shifted, and meanwhile, the rotating speed of the front-drive motor is controlled to be quickly reduced to the target rotating speed, so that the synchronizer can be quickly shifted to the target gear, and the direct-drive mode upshift requirement of a vehicle in a low-vehicle-speed scene can be met; and the gear shifting process is more coherent and reliable.

    本申请提供了一种混动车辆换挡控制方法、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:在车辆处于直驱模式且针对目标挡位的换挡请求为激活状态的情况下,控制前驱电机的扭矩降低至目标扭矩,并控制同步器摘挡;在同步器摘挡成功的情况下,控制前驱电机的转速降低至目标转速;在确定前驱电机的扭矩和前驱电机的转速满足同步器挂挡条件的情况下,控制同步器挂入目标挡位。本申请实施例通过主动控制前驱电机的扭矩降低至目标扭矩,能够实现同步器快速摘挡,同时控制前驱电机的转速快速降低至目标转速,使同步器能够快速挂入目标挡位,不仅能够满足车辆在低车速场景下的直驱模式升档需求,还能使换挡过程更为连贯可靠。
