The invention discloses a gear shifting torque compensation method and device for a four-wheel-drive vehicle, the vehicle and a storage medium. The method comprises the steps that it is determined that the vehicle is in a rear axle gear shifting state; obtaining driving information of the vehicle; determining the distribution torque of a rear axle driving motor of the vehicle according to the driving information; according to the distribution torque of the rear axle driving motor, the request torque of a front axle of the vehicle is determined; and torque compensation is conducted on rear axle gear shifting through the request torque of the front axle, so that the torque of the whole wheel end does not change, it is guaranteed that the torque loss of the wheel end does not exist, the problem of unsmooth vehicle gear shifting cannot be caused by rear axle gear shifting, the gear shifting quality of rear axle gear shifting is good, and therefore the driving experience is improved.
本发明公开了一种四驱车辆的换挡扭矩补偿方法、装置、车辆及存储介质,所述方法包括:确定车辆处于后桥换挡状态;获取所述车辆的行驶信息;根据所述行驶信息,确定所述车辆的后桥驱动电机的分配扭矩;根据所述后桥驱动电机的分配扭矩,确定所述车辆的前桥的请求扭矩;通过所述前桥的请求扭矩对后桥换挡进行扭矩补偿,使得整个轮端扭矩不发生变化,保证轮端无扭矩损失,后桥换挡不会引起车辆换挡不平顺的问题,后桥换挡的换挡质量好,从而提升驾驶体验。
