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.

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.

Abstract: A method is described for controlling an automatic transmission of a vehicle during deceleration arising from a force resisting forward movement arising from an incline grade and a vehicle mass. The force of resistance to forward movement is determined at least based upon the incline grade. A destination gear is calculated based upon a set of gear-specific output curves and the force of resistance. The destination gear is compared to a current gear within which the machine is operating. The programmed controller executes an early downshift schedule when the destination gear is at least two positions lower than the current gear, thereby initiating a series of downshifts of the automatic transmission from the current gear to the destination gear. During each gear shift performed according to the early downshift schedule, shifting occurs at a cross-over point between output curves of current and next lower gears.

Abstract: A system and method are provided for grade-based anti-hunt shift control of an automatic transmission powering a machine. A shift controller determines a recommended gear in which to operate the transmission and sets an anti-hunt timer upon recommending a shift from a first gear to a second gear. The anti-hunt timer prevents a subsequent shift back to the first gear while the anti-hunt timer is running. A grade-based controller is configured to track machine operation and to determine when the machine operational factors change such that an estimated steady state gear differs from the second gear. When such a change is encountered, the grade-based controller clears the anti-hunt timer and sets a secondary timer. The clearing of the anti-hunt timer allows a downshift to accommodate the detected grade while the setting of the secondary timer prevents a subsequent clearing of the anti-hunt timer while the secondary timer is running.

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.

Abstract: A drivetrain system is disclosed for use with a machine having a work tool. The drivetrain system may have a transmission with a plurality of clutches. The drivetrain system may also have an input device movable by an operator to generate a first signal indicative of a desired selection of a park setting or one of a plurality of travel settings, a sensor configured to generate a second signal indicative of loading of the work tool, and a controller in communication with the input device, the sensor, and the transmission. The controller may be configured to anticipate completion of a loading cycle based the second signal, and to selectively cause at least a first of the plurality of clutches to engage in a combination that produces one of the plurality of travel settings based on the anticipated completion of the loading cycle, notwithstanding the desired selection from the input device being the park setting.
