The invention relates to a vehicle engine torque correction method, terminal equipment and a storage medium. The method comprises the following steps: collecting a vehicle state data set of a vehicle,wherein the vehicle state data set comprises an accelerator depth, an actual torque percentage, an engine rotating speed, a clutch state and a gear state; filtering the acquired data set, and filtering the data of a neutral position and a semi-clutch period; deriving the accelerator depth according to the actual torque percentage and the engine rotating speed in the data set, and extracting the data set of which the ratio of two derivatives is greater than a threshold value; fitting the extracted data set to a cubic equation to obtain an actual torque calculation equation; substituting x = 100 into the actual torque calculation equation to solve the value of y, and judging whether the actual maximum torque is the identified maximum torque or not according to the relationship between y andthe range threshold. The actual maximum torque and the marked maximum torque can be distinguished, and then the actual torque of the engine can be accurately calculated.

    本发明涉及一种车辆发动机扭矩校正方法、终端设备及存储介质,该方法中包括:采集车辆的车辆状态数据集,其中车辆状态数据集包括油门深度、实际扭矩半分比、发动机转速、离合状态和档位状态;对采集的数据集进行过滤,过滤空档和半离合时期的数据;将数据集中的实际扭矩半分比和发动机转速分别对油门深度求导,提取出两个导数的比值大于阈值的数据集;将提取出的数据集对三次方程拟合,得到实际扭矩计算方程;将x=100代入实际扭矩计算方程中求解y的值,根据y与范围阈值的关系判断实际最大扭矩是否为标识最大扭矩。本发明能够区别实际最大扭矩和标识最大扭矩,进而准确的计算出发动机的实际扭矩。
