The invention discloses a torque control method, device and equipment of a four-wheel-drive vehicle and a storage medium, and relates to the technical field of vehicles, and the torque control method of the four-wheel-drive vehicle comprises the steps that when a driving mode switching instruction is received, a torque distribution ratio threshold value is determined according to current vehicle operation parameters and a distribution ratio mapping relation; determining a target torque distribution ratio according to the current torque distribution ratio and the torque distribution ratio threshold value; and controlling the torque of the four-wheel-drive vehicle according to the target torque distribution ratio. The distribution ratio is processed in the switching process from two-wheel drive to four-wheel drive, and the torque lost by the torque increment on the new drive shaft in the limited process is compensated by the other drive shaft, so that torque filtering is carried out on the working condition of tooth beating of the motor gear and the shaft end gear, and the tooth beating phenomenon is avoided.

    本申请公开了一种四驱车辆的扭矩控制方法、装置、设备及存储介质,涉及车辆技术领域,所述四驱车辆的扭矩控制方法包括:在接收到驱动模式切换指令时,根据当前车辆运行参数和分配比映射关系确定扭矩分配比阈值;根据当前扭矩分配比和所述扭矩分配比阈值确定目标扭矩分配比;根据所述目标扭矩分配比对四驱车辆的扭矩进行控制。通过在两驱到四驱的切换过程中对分配比进行处理,且新的驱动轴上的扭矩增量在受限过程中所损失的扭矩会由另一个驱动轴来补偿,进而实现了对电机齿轮与轴端齿轮打齿的工况进行扭矩滤波,以避免打齿现象的发生。
