20090006007 | SYSTEM AND METHOD FOR MEASURING MACHINE ROLLING RESISTANCE - 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. | 01-01-2009 |
20090006540 | System and method for remote machine data transfer - A method for data transfer between a client system and a server comprises receiving one or more user-defined file transfer specifications and establishing a communication channel between a client system and a server system based on the file transfer specifications. The method also includes initializing transfer of operation data between the client system and the server system via the communication channel. The method further includes providing an exception notification to one or more user-designated recipients if the transfer of the operation data between the client system and the server system is inconsistent with the file transfer specifications. | 01-01-2009 |
20090063031 | Performance-based haulage management system - 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. | 03-05-2009 |
20090063226 | Systems and methods for improving haul route management - A method for managing haul routes in work environments comprises receiving performance criteria associated with a haul route and establishing a target total effective grade for at least one machine associated with the haul route based on the performance criteria. The method also includes collecting performance data associated with the at least one machine. A drive axle torque of the at least one machine is determined and an actual total effective grade associated with the at least one machine is estimated. The at least one machine is identified as an underperforming machine if the actual total effective grade for the at least one machine exceeds the target total effective grade. An average total effective grade for the at least one machine is determined as a function of the actual total effective grade. A haul route deficiency is identified if the average total effective grade exceeds a threshold level. | 03-05-2009 |
20090099707 | Systems and methods for improving haul road conditions - A method for improving haul road surface conditions comprises collecting performance data associated with at least one machine operating on a haul route and determining a rolling resistance of each of the at least one machine based on the performance data. An average rolling resistance associated with one or more portions of the haul route is determined based on the rolling resistance of each of the at least one machine. The one or more portions of the haul route are identified as irregular if the average rolling resistance of the one or more portions exceeds a threshold resistance value. A proposed modification to the irregular portion of the haul route is generated, and performance of the at least one machine is simulated based on the proposed modification. The method also includes outputting results of the simulated performance. | 04-16-2009 |
