  • Patent number: 10094704
    Abstract: A system for estimating a payload includes a torque sensor, a grade detector, and a machine acceleration sensor. A controller compares the angle of inclination to its threshold, compares the rate of change in the angle of inclination to its threshold, and compares the machine acceleration to its threshold. An estimate of the payload is determined based upon the output torque from the prime mover, the angle of inclination of the machine, and the unloaded mass but only if the angle of inclination of the machine is greater than the angle of inclination threshold, the rate of change in the angle of inclination is less than the inclination rate of change threshold, and the machine acceleration is less than the acceleration threshold.

  • Patent number: 10011173
    Abstract: A powertrain system for a machine is described. The powertrain system includes a power source configured to provide a torque output. The powertrain system further includes a first drivetrain coupled to the power source, to drive a first set of ground engaging members, and a second drivetrain coupled to the power source to drive the second set of ground engaging members. The powertrain system further includes a controller having one or more lug curve maps defining a maximum allowed torque value of the power source for a current operating condition of the machine. The controller is configured to determine a parasitic load due to the second drivetrain, and adjust the torque output of the power source based on the determined parasitic load to maintain a rimpull performance of the machine, where the adjusted torque output is limited by the maximum allowed torque value.

  • Patent number: 8903612
    Abstract: A programmable controller implemented method of determining occurrence of bed loading events in a hauling machine. The method includes determining if the machine was stationary for a period, if the bed is in a loading position, other factors contributed to movement of the machine, calculating a bounce amplitude based upon a filtered machine accelerometer signal, comparing the amplitude with a constant reflecting a minimum amplitude, and identifying a loading event for an amplitude greater than the constant, if the machine has been stationary for a given period, the bed in a loading position, and no other factors caused machine movement.

  • Publication number: 20140324302
    Abstract: A method implemented by a programmable controller to estimate the payload mass in a bed of a moving hauling machine. The method includes determining whether the machine is at a steady acceleration and grade, estimating transmission torque, calculating axle torque at at least one of the ground engaging elements, calculating force at said ground engaging element, determining the acceleration of the machine, calculating mass of the machine with the payload, adjusting the calculated mass of the machine with the payload based upon an estimated machine mass and rolling resistance, and providing an estimate of the mass of the payload.

  • Patent number: 8700274
    Abstract: A method implemented by a programmable controller in a hauling machine having an engine, moveable ground engaging elements, and a bed actuable by at least one hoist cylinder controlled by an operator hoist control device, determines whether the bed is empty by determining a position of the operator hoist control device, applying a gain dependent upon the position, applying an integrator over time to provide a resultant hoist figure, comparing the resultant hoist figure to a hoist minimum constant, and, if the hoist figure is less than or equal to the hoist maximum constant, concluding that the bed is empty.

  • Patent number: 8655505
    Abstract: A worksite management system for use with a mobile machine is disclosed. The worksite management system may have a control module located onboard the mobile machine and configured to store a least one operational relationship, and an offboard controller located at a worksite of the mobile machine in communication with the control module. The offboard controller may be configured to generate an analysis of machine performance at the worksite. The offboard controller may be further configured to cause remote reconfiguration of the at least one operational relationship based on the analysis to positively affect performance of the mobile machine.

  • Patent number: 8463460
    Abstract: A worksite management system for use with a mobile machine is disclosed. The worksite management system may have a control module located onboard the mobile machine and configured to control operations of the mobile machine, and a controller in communication with the control module. The controller may be configured to anticipate a non-failure machine performance irregularity, and determine an adjustment to an operation of the mobile machine that positively affects the machine performance irregularity. The controller may also be configured to cause implementation of the adjustment before the machine performance irregularity occurs.

  • Patent number: 6973923
    Abstract: An internal combustion engine fuel system applies injection control pressure to fuel injectors (26) to force fuel into combustion chambers (28). A processor of a control system (22) develops data values for injection control pressure set-point (ICPC—T13) representing desired injection control pressure and evaluates (134) the injection control pressure set-point data values for compliance with an allowable dynamic range defined by a data value for a minimum dynamic limit correlated with engine speed (N) from a function generator (132) and a data value for a maximum dynamic limit correlated with engine temperature (EOT) from a function generator (130). The processor limits the data value of desired injection control pressure that is subsequently processed to control injection control pressure applied by the fuel system to the fuel injectors to the allowable dynamic range.

  • Patent number: 6850832
    Abstract: A schedule (164, 166) correlates data values of closed-loop gain (KP, KI) with engine temperature values (EOT) and engine speed values (N). A control strategy develops a data value (ICPC_DES) representing desired injector control pressure (ICP) set-point, processes ICPC_DES and a data value (ICP_MPA) representing actual ICP to develop ICP error data value (ICP_ERR) for closed-loop P-I control (160, 162) of actual ICP. Data values for closed-loop proportional and integral gains are obtained from the schedule based on measured engine temperature and measured engine speed. ICP become less subject to undesirable fluctuations that might otherwise change fuel injection quantity in ways detrimental to attainment of desired tailpipe emission objectives.
