发明名称 System and method for measuring machine rolling resistance
摘要 A method of measuring rolling resistance of a machine is disclosed. The method may include determining a drive axle torque value of the machine and calculating a total effective grade value using the drive axle torque value. The method may further include determining at least one drivetrain efficiency loss factor value and calculating a total drivetrain efficiency loss value of the machine using the at least one drivetrain efficiency loss factor value. The method may also include determining position data of the machine and calculating an actual grade value based on the position data. The method may additionally include calculating a rolling resistance value of the machine by subtracting the actual grade value and the drivetrain efficiency loss value from the total effective grade value and outputting the rolling resistance value.
