  • Method of optimized gear selection on high speed directional shifts
    Patent number: 9689490
    Abstract: Methods for machine velocity change gear selection and shift execution are disclosed. A current velocity and a maximum velocity change for a work machine from the current velocity may be determined. The maximum velocity change may be based on a maximum amount of energy expended to change the velocity of the work machine without exceeding an operational limit of a work machine component. A selected machine velocity change target gear may be a highest one of the available gears that will not cause a difference between the current velocity and an end of shift velocity of the work machine that is greater than the maximum velocity change so that the maximum amount of energy will not be exceeded. Factors affecting the maximum velocity change may include the grade, the mass of the work machine, and a transmission oil temperature.
