Provided is a vehicle that can improve vehicle posture control or operation performance during accelerating turn. A vehicle is provided with: a left drive wheel and a right drive wheel connected to a motor; a required drive power amount input device for inputting a required drive power amount; and a required turn amount input device for inputting a required turn amount. The vehicle further includes a turn control device that adjusts a power difference between the left drive wheel and the right drive wheel on the basis of a time derivative value of the required drive power amount in addition to the required turn amount.

An integrated electronic drive unit constructed in accordance to one example of the present disclosure includes a differential, a first axle, a second axle and a secondary power system. The differential includes a ring gear fixed for concurrent rotation with a differential case. The differential has a plurality of pinion gears rotatably mounted to the differential case and meshed with first and second side gears. The first axle is coupled to the first side gear. The second axle is coupled to the second side gear. The secondary power system is selectively engageable to at least one of the first and second axles. The integrated electronic drive unit is operable in an open differential mode, a braking mode, an electric vehicle start mode and a torque vectoring mode.

A vehicle having a four-wheel-drive system including an auxiliary portion that has an auxiliary driveshaft and drive means between the auxiliary driveshaft arranged to releasably connect a second group of wheels to the driveline via a releasable torque transmitting device. The releasable torque transmitting device is operable to allow slippage of the input portion with respect to the output portions, thereby to vary an amount of torque that is transmitted to the second group of wheels.

Provided is a control device for a four-wheel drive which can maintain driving stability while restraining noise and vibration. A control device includes: a second control device that, when at least one of front wheel has slipped, engages a dog clutch after rotating a propeller shaft by a rotational force transmitted via first and second friction clutches; and a third control device that, if a predetermined condition is satisfied when the front wheels are not slipping, engages the dog clutch after rotating the propeller shaft by the rotational force transmitted via the first and second friction clutches. The time required to synchronize the dog clutch by the third control device is longer than that required to synchronize the dog clutch by the second control device.

A vehicle differential disconnect assembly can include a differential case, a differential gear set, and a torque distribution device. The differential gear set is carried within the differential case. The torque distribution device transfers torque between the differential gear set and side shafts of the accompanying vehicle driveline. The torque distribution device can include a clutch pack and an actuator assembly. The clutch pack is located at a first side of the differential case relative to the differential gear set, and the actuator assembly is located at a second side of the differential case relative to the differential gear set. The actuator assembly has a mover that transmits movement to the clutch pack when the actuator assembly actuates and deactuates the clutch pack.
