A manual gearbox section for a vehicle includes a section input, a section output, a freewheel device situated in a freewheel torque path between the section input and the section output, and a clutch device situated in a clutch torque path between the section input and the section output. The clutch torque path forms a bypass path with respect to the freewheel device and/or the freewheel torque path. The freewheel device is in the form of a rotational-speed-dependent freewheel device. The freewheel device is in a freewheeling state at a first rotational speed and in a coupled state at a second rotational speed. The second rotational speed is higher than the first rotational speed.

Non-limiting examples of the present disclosure relate to generation and implementation of a new security protocol that is used to secure common data access transactions across distributed network examples. An exemplary proof of verification protocol is disclosed that implements consensus security mechanisms across a plurality of distributed nodes, which may be utilized to validate owners of data in common data access transactions. Extending principles of blockchain security to common data access transactions and Internet of Things (IOT) networking requires a solution that: improves speed in transactional processing; reduces computational complexity; and presents efficient, secure and repeatable validation for owners of data in distributed networking environments. An exemplary proof of verification protocol provides such technical advantages by validating both user-specific data for a subscriber of an application/service and session data for user activity (past and present) within the application/service.

A driving device includes a first one-way clutch OWC1 provided on a power transmission path between a driving source and a driven portion which becomes in an engaged state when rotational power in one direction of the driving source side is input to the driven portion side and becomes in a disengaged state when rotational power in the other direction of the driving source side is input to the driven portion side and which becomes in a disengaged state when rotational power in one direction of the driven portion side is input to the driving source side and becomes in an engaged state when rotational power in the other direction of the driven portion side is input to the driving source side, a connection/disconnection unit which is provided in parallel with the first one-way clutch OWC1 on the power transmission path, and a second one-way clutch OWC2 provided in parallel with the first one-way clutch OWC1 and in series with the connection/disconnection unit on the power transmission path which performs an operation opposite to that of the first one-way clutch OWC1.

One solenoid valve included in a hydraulic pressure control device has at least two functions among the following (1) to (6) functions, (1) switching a state of a two-way clutch, (2) switching a state of a parking lock mechanism, (3) switching the supply of hydraulic pressure to a first brake that is put into an engaged state when a gear stage selected when driving of a vehicle starts is set, (4) controlling a line pressure adjustment valve so that a decrease in a line pressure is prevented when the temperature of a hydraulic fluid is a first predetermined temperature or higher, (5) preventing the occurrence of a creep phenomenon in a neutral range when the temperature of the hydraulic fluid is a second predetermined temperature or lower, and (6) boosting a line pressure by performing switching to another linear solenoid valve when the line pressure adjustment valve has failed.

A vehicle drive apparatus including a first rotating shaft driven by torque from a driving source, a second rotating shaft disposed around the first rotating shaft, a motor-generator including a rotor, a first rotor fitted on the first rotating shaft through a first fitting portion, a second rotor fitted on the second rotating shaft through a second fitting portion and fitted in a shaft of the rotor through a third fitting portion, a first and second bearings rotatably supporting the second rotating shaft and the shaft of the rotor, and a one-way clutch disposed in an inward side of the rotor and between the first and second bearings. A radial gap at the first fitting portion is larger than a radial gap at the second fitting portion, and is larger than a radial gap at the third fitting portion.

The invention relates to a drive train for a hybrid vehicle with an internal combustion engine, with a transmission and with an electric machine, wherein the electric machine is arranged between the internal combustion engine and the transmission. The drive train can be provided in a simple, economical and/or space-saving manner in that the transmission comprises at least one overrun-enabled forward gear transmitting traction torque only and at least one overrun-free forward gear. A hybrid vehicle can be operated with a drive train of this kind easily and efficiently in that, when an overrun-enabled forward gear transmitting only traction torque is engaged and while the vehicle speed lies below a certain engagement speed for an overrun-free forward gear and at least one criterion for the presence of a driving torque is established or satisfied, the transmission is shifted into the overrun-free forward gear.

An automatic transmission for improving responsiveness until reverse movement is possible. When the range is switched from a parking range to a reverse range, P lock release control for releasing a parking state starts. When a two-way clutch is in a reverse rotation prevention state, hydraulic pressure is supplied to a first clutch, a third clutch, and a third brake, and a process in a reverse side preparation mode starts. When the first clutch is in a connected state and a rotational speed of an input shaft is a predetermined rotational speed, whether a parking piston of a parking lock mechanism is at an unlock position is determined. When it is at the unlock position, a driving source is requested to restrict an output torque. Then, hydraulic pressure is supplied to the two-way clutch, and the two-way clutch is switched from a reverse rotation prevention state to a fixed state.

A control apparatus for a vehicle drive-force transmitting apparatus which defines a first drive-force transmitting path provided with a first clutch and a two-way clutch and a second drive-force transmitting path provided with a continuously variable transmission and a second clutch. The control apparatus switches the two-way clutch from its lock mode to its one-way mode, when the second drive-force transmitting path is to be established in place of the first drive-force transmitting path. The drive-force transmitting apparatus includes a hydraulic actuator configured to control switching of the two-way clutch between the lock mode and the one-way mode. When a request for establishing the second drive-force transmitting path in place of the first drive-force transmitting path is made during forward running of the vehicle with the two-way clutch being in the lock mode, the control apparatus executes a dither control for fluctuating a hydraulic pressure applied to the hydraulic actuator.

A mechanical front wheel drive roller wedging control system includes a 4WD switch in a vehicle operator station, a roller cage drag mechanism electrically activated by the 4WD switch and providing a drag on a roller cage if the 4WD switch is in an on position, and a throttle pedal switch actuated by the throttle pedal and that deactivates the roller cage drag mechanism when the throttle pedal is released. In an alternative embodiment, a controller may deactivate the roller cage drag mechanism when a throttle position sensor or engine speed sensor is below a minimum value.

The subject disclosure relates to a coil module assembly for a bi-directional clutch assembly having at least one active clutch. The coil module assembly includes a housing having an actuator housing portion and a PCB housing portion. An electromagnetic actuator is disposed in the actuator housing portion for effectuating pivotal movement of the active strut from an unlocked position to a locked position in response to an energization of the electromagnetic actuator. An integrated printed circuit board (PCB) is disposed in the PCB housing portion and is in electrical communication with the electromagnetic actuator for selectively energizing the electromagnetic actuator. The housing further includes a thermally decoupled housing portion which is disposed between the actuator housing portion and the PCB housing portion for thermally decoupling, i.e., reducing heat transfer, from the electromagnetic actuator to the PCB during selective energization of the electromagnetic actuator.
