The present disclosure relates to a method for computing a vehicle mass, a terminal device and a storage medium. The method includes: S1: collecting engine torque data and electronic horizon data of a vehicle in real time, and setting a time interval T; S2: determining whether two sampling points whose gradient value difference between a post sampling point and a previous sampling point is greater than a gradient value difference threshold exist within the time interval T; and then entering S3 until they exist; S3: determining whether the two sampling points are on a same road; if so, entering S4; otherwise, returning to S2; S4: determining whether the road between the two sampling points is a straight road; if so, entering S5; otherwise, returning to S2; S5: determining whether a difference between engine torques corresponding to the post sampling point and the previous sampling point is greater than a torque difference threshold; if so, entering S6; otherwise, returning to S2; S6: calculating the vehicle mass according to the engine torques and gradient values corresponding to the two sampling points. The present disclosure can calculate the vehicle mass when driving at a constant speed, and is suitable to be used in the hilly working conditions with large terrain changes in combination with the electronic horizon.
