The invention relates to a vehicle mass calculation method, terminal equipment and a storage medium, and the method comprises the steps: S1, collecting the engine torque data and electronic horizon line data of a vehicle in real time, and setting a time interval T; S2, judging whether two sampling points of which the gradient value difference is greater than a gradient value difference threshold value exist in the T, and entering S3 until the two sampling points exist; S3, judging whether the two sampling points are located on the same road, and if yes, entering S4; otherwise, returning to S2; S4, judging whether a road between the two sampling points is a straight road, and if yes, entering S5; otherwise, returning to S2; S5, judging whether the difference value of the engine torque corresponding to the rear sampling point and the engine torque corresponding to the front sampling point is larger than a torque difference value threshold value, and if yes, executing S6; otherwise, returning to S2; and S6, calculating the mass of the vehicle according to the engine torque and the slope value corresponding to the two sampling points. The mass of the vehicle can be calculated when the vehicle runs at a constant speed, and the method is suitable for being used in combination with the electronic horizon under the hilly working condition with large topographic change.

    本发明涉及一种车辆质量计算方法、终端设备及存储介质,该方法中包括:S1:实时采集车辆的发动机扭矩数据和电子地平线数据,设定时间间隔T;S2:判断T内是否存在坡度值差值大于坡度值差值阈值的两个采样点,直到存在时,进入S3;S3:判断两个采样点是否处于同一道路上,如果是,进入S4;否则,返回S2;S4:判断两个采样点之间道路是否为直道,如果是,进入S5;否则,返回S2;S5:判断后采样点与前采样点对应的发动机扭矩的差值是否大于扭矩差值阈值,如果是,进入S6;否则,返回S2;S6:根据两个采样点对应的发动机扭矩和坡度值,计算车辆的质量。本发明可以使车辆在匀速行驶时计算其质量,适合结合电子地平线在地形变化较大的丘陵工况使用。
