  • Patent number: 11906031
    Abstract: A vehicle includes: an interrupter including a first connector connected to a driving source, a second connector connected to a transmission, and a fluid in a gap between the first and second connectors; and processing circuitry. The processing circuitry receives flowability information indicating a value related to flowability of the fluid. The processing circuitry determines whether or not a predetermined power interruption condition is satisfied. When the above condition is satisfied, and the processing circuitry determines that the value is less than a predetermined reference value, the processing circuitry controls the speed change actuator to set the transmission to a first gear stage. When the condition is satisfied, and the processing circuitry determines that the value is not less than the reference value, the processing circuitry controls the speed change actuator to set the transmission to a second gear stage having a lower reduction ratio than the first gear stage.

  • Patent number: 11859715
    Abstract: A transmission is shifted into a reverse state. The transmission includes a clutch. The clutch includes a pocket plate, a notch plate, a first strut housed within a pocket of the pocket plate, and a second strut housed within another pocket. A command is received to shift the transmission to reverse. It is then determined whether the at least one second strut has retracted into the pocket plate. If it remains extended, the first actuator is activated. A first rotational torque is applied to the notch plate in a direction allowing the notch plate to abut the first strut. By doing so, the second strut is released from abutting engagement with the notch plate. A second rotational torque is applied to the notch plate opposite the first rotational torque to rotate the notch plate out of engagement with the first strut, resulting in the transmission entering the reverse state.

  • Patent number: 11813944
    Abstract: An electrified tractor includes a vehicle body, an electric motor, a battery, an inverter configured to control input-output electric power of the battery, a wheel for traveling, and a control device. On condition that the electrified tractor travels inside a restriction area determined in advance as one condition, the control device controls the inverter such that the input-output electric power of the battery falls within a specific electric power range determined in advance. The control device determines whether or not there is a possibility that the electrified tractor moves from the restriction area to outside the restriction area. In a case where an affirmative determination is made in a determination process during a restriction process, the control device expands the specific electric power range as compared with a case where a negative determination is made in the determination process.
