  • Patent number: 9752304
    Abstract: A power transmission includes first and second clutches for switching a transmission path for a driving force therein. A clutch controlling unit provided for a work vehicle is configured to switch the transmission path from one to the other of first and second modes when a speed ratio parameter reaches a mode switching threshold. The clutch controlling unit is configured to keep setting the transmission path in the other mode even when the speed ratio parameter again reaches the mode switching threshold until a switching prohibition period having a predetermined initial value expires as long as a period of time elapsed after mode switching is included in the switching prohibition period. A trigger detecting unit provided for the work vehicle is configured to make the switching prohibition period expire when detecting a predetermined operation in the switching prohibition period.

  • Patent number: 9745722
    Abstract: A power transmission includes first and second clutches for switching a transmission path for a driving force. A work vehicle includes a clutch controlling unit and an engine controlling unit. The clutch controlling unit is configured to determine which of first and second modes the transmission path is switched into based on which of a range of greater than or equal to a mode switching threshold and a range of less than or equal to the mode switching threshold a speed ratio parameter falls into, and is configured to output a clutch command signal causing one of the first and second clutches to be engaged corresponding to the determined mode. The engine controlling unit is configured to apply an offset to a rotational speed of an input shaft such that after switching into the determined mode, the speed ratio parameter deviates from the mode switching threshold in the switched mode.

  • Publication number: 20160082950
    Abstract: A power transmission includes first and second clutches for switching a transmission path for a driving force. A work vehicle includes a clutch controlling unit. When a speed ratio parameter transitions within a predetermined first range including a mode switching threshold after the speed ratio parameter reaches the mode switching threshold and then the transmission path is switched from a first mode to a second mode, the clutch controlling unit is configured to output a clutch command signal for disengaging the first clutch and output a clutch command signal for engaging the second clutch to keep setting the transmission path in the second mode even when the speed ratio parameter again reaches the mode switching threshold.

  • Publication number: 20160040394
    Abstract: When a clutch is in the disengaged state, the predicted engagement time determining unit determines a predicted engagement time. The predicted engagement time is the predicted value for the time required from the beginning of the clutch engagement until engagement is complete. The speed ratio parameter estimating unit determines an estimated value for a speed ratio parameter after the elapse of the predicted engagement time from the current point in time. When the estimated value for the speed ratio parameter reaches a mode-switching threshold value, a clutch control unit outputs a clutch command signal for causing the clutch to engage.
