The embodiment of the invention provides a torque fault processing method and device, a vehicle and a storage medium. The method comprises the steps that the current motor fault degree of the vehicle is obtained; the response motor fault degree is a preset first influence range, a correction coefficient value and a vehicle demand torque are obtained, a motor torque distribution value is obtained according to the correction coefficient value and the vehicle demand torque, and the motor torque is output based on the motor torque distribution value; and/or, the response motor fault degree is within a preset second influence range, and output of the motor torque is prohibited; wherein the preset second influence range is larger than the preset first influence range. Based on the current motor fault degree of the vehicle, under the condition of different influence ranges caused by the motor fault, different processing measures of torque redistribution adjustment or torque output prohibition are carried out based on the calculated motor torque distribution value, and different torque processing measures are adopted for different motor fault degrees. Therefore, the influence of single torque fault processing on vehicle driving is avoided.

    本发明实施例提供了一种扭矩故障处理方法、装置、车辆及存储介质,所述方法包括:获取车辆当前的电机故障程度;响应电机故障程度为预设第一影响范围,获取修正系数值和车辆需求扭矩,根据修正系数值和车辆需求扭矩得到电机扭矩分配值,并基于电机扭矩分配值输出电机扭矩;和/或,响应电机故障程度为预设第二影响范围,禁止输出电机扭矩;其中,预设第二影响范围大于预设第一影响范围。通过基于车辆当前的电机故障程度,在电机故障所引起的不同影响范围的情况下,基于所计算得到的电机扭矩分配值进行扭矩重新分配调整或者禁止扭矩输出的不同处理措施,实现不同的电机故障程度采取不同的扭矩处理措施,以避免单一的扭矩故障处理而影响车辆行驶。
