  • Patent number: 10731717
    Abstract: A power transmission device for a vehicle includes a control unit adapted to automatically control engagement or disengagement of a clutch, and is further equipped with a clutch lever for manually engaging or disengaging the clutch. The power transmission device includes a manual mode in which the clutch is engaged or disengaged by a driver performing an engagement or disengagement operation with the clutch engagement/disengagement operating element and an automatic mode in which the clutch is engaged or disengaged under the control of the control unit without the driver performing the engagement or disengagement operation. The manual mode or the automatic mode is selectable by the driver. In the manual mode, it is further possible to select a plurality of control modes with differing levels of intervention of the automatic control.

  • Patent number: 10731735
    Abstract: A device is described for transmitting mechanical power that allows variable output-speed to input-speed ratios. Gear sets such as epicyclic gear sets have components that rotate about a common axis selectively at the same rotational speed and at different relative rotational speeds as determined by at least one of fluid flow and fluid pressure. One or more inlet ports and fluid passageways introduce a working fluid into one or more volume spaces between the components. The internal pressure and flow of the working fluid through the device is controlled to provide substantially infinite variability of the output-speed to input-speed ratios for applications where, for example, an engine provides the mechanical power for propelling a vehicle.

  • Patent number: 10724608
    Abstract: There is provided a transmission control device capable to switching a switching mechanism quickly. A transmission control device ECU controls an automatic transmission (3) and can receive information about a slope from a front and rear G sensor. The automatic transmission (3) includes a two-way clutch (F1) as a switching mechanism that is switchable between a reverse rotation prevention state in which forward rotation of a rotatable carrier (Cb) (eleventh element) is allowed and reverse rotation is prevented and a fixed state in which rotation of the element is prevented. When the range is switched to a parking range and a vehicle is not stopped on a slope, the transmission control device ECU switches the two-way clutch (F1) to the fixed state.

  • Patent number: 10696289
    Abstract: Systems and methods are shown for meeting wheel torque demand in a hybrid vehicle with an engine, a dual clutch transmission coupled to a driveline of the vehicle downstream of the engine, and an electric machine coupled to the driveline downstream of the dual clutch transmission. In one example, a method includes transferring transmission input torque through a clutch of the dual clutch transmission controlled to a first capacity, and, in response to a desired transmission input torque exceeding the capacity, increasing torque output of the electric machine coupled downstream of the dual clutch transmission to assist in meeting a wheel torque demand. In this way, a driver-requested increase in acceleration may be met under conditions where transmission input torque is limited by clutch capacity.

  • Patent number: 10696370
    Abstract: Transmission systems and methods are for a marine propulsion device having an internal combustion engine that drives a propulsor. An input shaft is driven into rotation at a non-zero first rotational speed by the internal combustion engine. An output shaft drives the propulsor into rotation at a non-zero second rotational speed. A planetary gearset transfers power from the input shaft to the output shaft. A band brake is on the planetary gearset. Actuation of the band brake effects a gear change in the planetary gearset. A band brake actuator actuates the band brake to effect the gear change. A controller controls the band brake actuator. Based upon one or more operational characteristics of the marine propulsion device the controller is programmed to control the band brake actuator so that the second rotational speed is less than the first rotational speed.

  • Patent number: 10696178
    Abstract: A hybrid powertrain system and method includes a prime mover driving a generator/motor to produce an AC power output. The AC power output is applied to a rectifier which is controlled to transform the applied AC power to DC power to supply a DC Power bus at a selected voltage and current. An energy storage device is also connected to the DC power bus and the current flow between the energy storage device and the DC power bus is monitored and compared to preselected values and the results of that comparison are used to alter the operation of the rectifier to increase or decrease, as needed, the current provided to the DC power bus as electrical loads on the DC power bus change.

  • Patent number: 10661800
    Abstract: A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain includes first and second driven axles with a variable pivot angle hydraulic motor connectable to drive the first axle through engagement of a first clutch mechanism. A further motor is connected to drive the second axle. In operation, the pivot angle of the variable pivot angle hydraulic motor is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle at zero and parameter value continuing to vary due to the drive of the further motor, the first clutch mechanism is disengaged at a second parameter value, with the first and second parameter values separated by an interval determined at least partly by an operating characteristic of the first clutch mechanism.
