Title:
METHOD FOR CALCULATING MASS OF VEHICLE, AND TERMINAL DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/217957
Kind Code:
A1
Abstract:
Disclosed are a method for calculating the mass of a vehicle, and a terminal device and a storage medium. The method comprises: S1: collecting data of engine torques of a vehicle and data of an electronic horizon in real time, and setting a time interval T; S2: determining whether there are two sampling points within T, the slope difference value between which is greater than a slope difference threshold value, and proceeding to S3 until there are the two sampling points; S3: determining whether the two sampling points are on the same road, and if so, proceeding to S4, otherwise, returning to S2; S4: determining whether the road between the two sampling points is a straight road, and if so, proceeding to S5, otherwise, returning to S2; S5: determining whether the difference value between engine torques respectively corresponding to a rear sampling point and a front sampling point is greater than a torque difference threshold value, and if so, proceeding to S6, otherwise, returning to S2; and S6, calculating the mass of the vehicle according to the engine torques corresponding to the two sampling points and slope values. The method makes it possible to calculate the mass of a vehicle during constant-speed travelling of the vehicle, and is suitable for use, in combination with an electronic horizon, in a working condition of hills where the terrain changes greatly.
