The invention provides a vehicle torque control method, a storage medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, a high-speed shaft and a low-speed shaft are determined in a front axle driving shaft and a rear axle driving shaft, and under the condition that it is determined that the high-speed shaft meets the torque reduction enabling condition, a first shaft speed difference threshold value is determined based on working condition information of the vehicle; and determining whether the high-speed shaft meets a torque reduction control activation condition or not based on the first shaft speed difference threshold value and the shaft speed difference between the high-speed shaft and the low-speed shaft, and then performing torque reduction control on the high-speed shaft based on the shaft speed difference until the high-speed shaft meets a torque reduction control exit condition under the condition of determining that the high-speed shaft meets the torque reduction control activation condition. According to the embodiment of the invention, the first shaft speed difference threshold value can be dynamically adjusted according to the working condition information of the vehicle, so that the vehicle can timely and effectively adjust the torque of the high-speed shaft on the premise of not additionally configuring a differential mechanism, and the driving safety is effectively ensured while the power waste of the whole vehicle is avoided.
本申请提供了一种车辆扭矩控制方法、存储介质和车辆,属于车辆技术领域,本申请实施例通过在前桥驱动轴和后桥驱动轴中确定高速轴和低速轴,能够在确定高速轴满足降扭使能条件的情况下,基于车辆的工况信息,确定第一轴速差阈值,并基于第一轴速差阈值和高速轴与低速轴之间的轴速差,确定高速轴是否满足降扭控制激活条件,进而在确定高速轴满足降扭控制激活条件的情况下,基于轴速差对高速轴进行降扭控制,直到高速轴满足降扭控制退出条件。本申请实施例能够根据车辆的工况信息,动态调整第一轴速差阈值,使得车辆能够在不额外配置差速器的前提下,对高速轴进行及时有效的扭矩调节,在避免整车功率浪费的同时有效保证行车安全。
