  • Performance-based haulage management system
    Patent number: 8437924
    Abstract: A method for managing haul routes in work environments comprises collecting performance data associated with a machine operating in a work environment. The method also includes determining a drive axle torque of the machine and estimating a total effective grade associated with the machine based on the drive axle torque. The estimated total effective grade is compared with a threshold level and, if the estimated total effective grade exceeds the threshold level, a design performance of the machine may be simulated based on the calculated total effective grade. Design performance data is compared with the collected performance data, and a payload limit of the machine is adjusted if the design performance is inconsistent with collected performance data.
