SYSTEM AND METHOD FOR MEASURING MACHINE ROLLING RESISTANCE

摘要

A method of measuring rolling resistance of a machine (12) is disclosed. The method may include determining a drive axle torque value (46) of the machine and calculating a total effective grade value (48) 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 (50) of the machine using the at least one drivetrain efficiency loss factor value. The method may also include determining position data (52) of the machine and calculating an actual grade value (54) based on the position data. The method may additionally include calculating a rolling resistance value (56) 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.
