The invention provides a control method and device for uninterrupted gear shifting of a vehicle, the vehicle and a storage medium, and the method comprises the steps that when it is determined that a front axle gearbox meets gear shifting conditions, the front axle gearbox is controlled to conduct gear shifting; in the gear shifting process of the front axle gearbox, a driving motor is controlled to output transient available torque; determining a target request torque of the driving motor according to the transient available torque and an actual request torque of the driving motor; and controlling the front axle gearbox to shift gears without interruption according to the target request torque. In the gear shifting process of the front axle gearbox, the driving motor is controlled to output the transient available torque, so that the upper limit value of the available torque of the driving motor is increased, and it is guaranteed that the upper limit value of the available torque of the driving motor can meet the torque request of the driving motor in the gear shifting process; the torque falling phenomenon caused by insufficient torque of the driving motor in the gear shifting process of the front axle gearbox is avoided, and therefore it is guaranteed that no power loss exists in the gear shifting process, and meanwhile the gear shifting quality is improved.
本发明提出一种车辆无中断换挡的控制方法及装置、车辆和存储介质,方法包括:确定前桥变速箱满足换挡条件时,控制前桥变速箱换挡;当前桥变速箱换挡过程中,控制驱动电机输出瞬态可用扭矩;根据瞬态可用扭矩及驱动电机的实际请求扭矩确定驱动电机的目标请求扭矩;根据目标请求扭矩控制前桥变速箱无中断换挡。本发明在前桥变速箱换挡过程中,控制驱动电机输出瞬态可用扭矩,以提高驱动电机可用扭矩的上限值,保证换挡过程中驱动电机的可用扭矩上限能够满足驱动电机的扭矩请求,避免前桥变速箱换挡过程中驱动电机扭矩不足导致的扭矩跌坑现象,从而,在保证换挡过程无动力损失的同时,提高换挡质量。
