A controller of a four-wheel drive vehicle includes a first operation part that switches drive mode of the vehicle; a second operation part that switches off-road traveling modes indicating traveling modes for off-road driving of the vehicle; a transfer controller that controls the arrangement of a transfer device in accordance with the drive mode; a detector that detects the arrangement of the transfer device; a determiner that determines whether a switching of the traveling modes is permitted or not based on the drive mode and the arrangement detected by the detector; and a setter that sets the traveling modes of the vehicle based on the detected arrangement and input operations to the first operation part and the second operation part when the determiner determines the switching of the traveling modes is permitted, and maintains the current traveling mode when the determiner determines the switching of the traveling modes is not permitted.

A controller for a four-wheel drive vehicle includes a multi-information display, a first operation part for switching of drive modes, a second operation part for switching of off-road traveling modes, a transfer controller that controls the arrangement of a transfer device based on the drive mode, a detector that detects the arrangement of the transfer device, a setter that sets the traveling mode based on the detected arrangement and input operations to the first and second operation parts, and a display controller that instructs the multi-information display to display the drive mode based on the input operation to the first operation part and the detected arrangement and to display the traveling mode set by the setter. The display controller displays the drive mode and the traveling mode on a window when the switched drive mode is a locked drive mode and simultaneously turns off these modes after a predetermined time.

A drive switching apparatus includes an output member connected to a drive switching member and displacing the drive switching member to three shift positions by being rotated, a deceleration mechanism decelerating rotation of an input portion connected to an electric motor and outputting the rotation to an output portion, a rotation absorption mechanism including an elastic member interposed between an input element connected to the output portion and an output element connected to the output member, the rotation absorption mechanism absorbing rotation of the input element in a case where rotation of the output element is restricted during the rotation of the input element, aid a switch operation portion provided at the output element, the switch operation portion turning a switch on and off according to a rotational position of the output member in order to detect the shift positions of the drive switching member.

Some embodiments are directed to a control system for use with a vehicle having handlebars that are configured to enable vehicle steering. The handlebars define a pair of grasping portions that are disposed to facilitate grasping by a vehicle operator's hands. The vehicle also includes a powertrain and an accessory. The control system includes a manually actuable primary selector disposed adjacent one of the grasping portions to enable manual actuation while one of the vehicle operator's hands grasps the one grasping portion. The primary selector is configured to operate in a powertrain mode to control an aspect of the powertrain, and to operate in a separate accessory mode to control an aspect of the accessory. A manually actuable override selector is disposed adjacent the one grasping portion. The override selector is configured to be manually actuable to switch the primary selector between the powertrain mode and the accessory mode.

A vehicle differential disconnect assembly includes a differential case and a differential gear set carried within the differential case. The differential gear set includes a differential carrier rotatably supported within the differential case. A clutch ring includes interior spline splines engaged with exterior splines of the differential case and being movable to engage exterior splines on the differential carrier. An actuator assembly includes a solenoid with a plunger that engages a rocker that is pivotally mounted to a support structure and connected to the plunger. A shift fork is operably engaged with the clutch ring and slidably mounted for translation along an axis. The shift fork includes an engagement feature for receiving an end of the rocker, wherein activation of the actuator causes pivotal movement of the rocker to cause the shift fork to translate along the axis.

A power takeoff unit (PTU) for an all-wheel drive vehicle includes an input shaft configured to receive power, a main shaft, and a takeoff shift collar axially slidable between an engaged position connecting the input shaft to the main shaft and a disengaged position disconnecting the main shaft from the input shaft. Power received by the input shaft is transferred through the takeoff shift collar to the main shaft, through a main ring gear, a hypoid pinion gear, and through a pinion shaft when the takeoff shift collar is in the engaged position and wherein the main shaft is decoupled from the input shaft when the takeoff shift collar is in the disengaged position.
