A target value obtaining section obtains a target value for the difference in rotational motion between a first motor and a second motor and a target value for output torque. A torque command value calculating section calculates a torque command value for the first motor and a torque command value for the second motor that achieve both of the target value for the difference in rotational motion and the target value for the output torque by using an inverse model of a motion model corresponding to a merging system.

A bi-directional clutch assembly includes an outer race defining first and second strut pockets, an inner race defining ratchet teeth, a passive one-way clutch including at least two passive struts each supported in a corresponding first strut pocket for pivotal movement relative to the ratchet teeth, passive strut springs for normally biasing the passive struts into engagement with the ratchet teeth on the inner race, and a selectable one-way clutch having at least one active strut supported in the second strut pocket for pivotal movement between a non-deployed position disengaged from the ratchet teeth and a deployed position engaged with the ratchet teeth, and an armature ring fixed for rotation with the outer race and axially moveable between a non-actuated position and an actuated position, in which a strut engagement feature moves the active strut from its non-deployed position to its deployed position.

A freewheel for changing a transmission characteristic of a planetary transmission for a motor vehicle transmission. The freewheel has a first ring which has a first blocking contour, a second ring which is rotatable relative to the first ring and which has a second blocking contour, tiltable blocking bodies which can be caused to engage into the first blocking contour and into the second blocking contour, and a switching element for tilting the blocking bodies. The switching element, in a blocking position, clamps the blocking bodies immovably to the first blocking contour and to the second blocking contour, in a freewheel position, allows unidirectional freewheeling, and in an inactive position, holds the blocking bodies down on the first ring so as to be spaced apart from the second ring.

A gear unit has a differential with two planetary gearsets and gearset elements. A first gearset element of the first planetary gearset is connected to an input shaft, a second gearset element of the first planetary gearset is connected to a first output shaft, a third gearset element of the first planetary gearset is connected to a first gearset element of the second planetary gearset, a second gearset element of the second planetary gearset is connected to a housing, and a third gearset element of the second planetary gearset is connected to a second output shaft. A first output torque is transmittable to the first output shaft. A second output torque is transmittable to the second output shaft. An actuation mechanism is arranged between the first and second output shafts for a co-rotationally fixed connection between the output shafts when the actuation mechanism is actuated.

The present invention relates to a freewheel arrangement (4) having a freewheel (2), which comprises a first running ring (44), a second running ring (46), at least one clamping element (26; 28) that is between the first and the second running ring (44, 46) and is movable between a coupling position and a release position, and an actuating element (42) for adjusting the at least one clamping element (26; 28), wherein the actuating element (42) can be arranged on the first running ring (44) and is movable relative to the first running ring (44). A friction device (52) for generating a frictional force acting on the actuating element (42) is provided, the frictional force counteracting a drive force acting on the first running ring (44) so as to move the actuating element (42) relative to the first running ring (44). The present invention furthermore relates to a drivetrain (82) having such a freewheel arrangement (4).

A first gearset element is connected to the input shaft, a second gearset element is connected to the first output shaft, and a third gearset element is connected to a first gearset element of the second planetary gearset. A second gearset element is connectible to a second gearset element of the epicyclic gear train. A third gearset element is connected to the second output shaft. A first gearset element of the epicyclic gear train is connected to the input shaft. A third gearset element of the epicyclic gear train is connected to the stationary structural component.

A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.
