A vehicle includes motors each configured to drive a front wheel of the vehicle, an electronic limited slip differential (eLSD) between rear wheels of the vehicle, and a controller to, responsive to vehicle turning and a power of each of the motors being less than a maximum value, alter operation of the motors to increase a difference between the powers. Otherwise, the controller operates the eLSD to bias torque toward one of the rear wheels.

An emergency braking control system of a vehicle using a limited slip differential, may include a brake circuit formed by splitting hydraulic lines for left and right side drive wheels; a limited slip differential disposed to restrict the differential of the drive wheels; and a controller for determining whether or not the braking circuit failure occurs in a braking situation, and performing the engagement control of the limited slip differential, wherein the controller is configured to perform the engagement control of the limited slip differential to distribute a braking force to drive wheel connected to a hydraulic line where the braking circuit failure occurs when the brake circuit failure occurs in the braking situation.

A vehicle including a coupling device that includes (a) an engagement clutch mechanism for coupling an input side engagement member that is coupled to a drive power source of the vehicle and an output side engagement member that is coupled to a drive wheel of the vehicle; and (b) a cam mechanism for assisting engagement of the input and output side engagement members depending on a differential torque by which the input and output side engagement members are rotated differentially. The vehicle includes a control device configured, when the engagement of the input and output side engagement members is to be released, to cause a braking force to be applied to one of the input and output side engagement members such that the differential torque is reduced.

A power plant is provided which is capable of not only achieving the improvement in responsiveness, weight reduction, and manufacturing cost reduction of the power plant, but also enhancing the efficiency of the vehicle. The rotational speeds of first to third rotary elements satisfy a collinear relationship in which the rotational speeds are aligned in a single straight line in a collinear chart in the mentioned order, with the first and second rotary elements being connected to a first rotating electric machine and wheels, respectively, and first and second blocking/connecting members of a first one-way clutch being connected to the first and second rotary elements, respectively. In a case where the first and second rotary elements rotate in a first predetermined rotational direction by transmission of rotational motive power from the first rotating electric machine, transmission of rotational motive power from the first blocking/connecting member to the second blocking/connecting member is blocked. In a case where the second and first rotary elements rotate in the first predetermined rotational direction by transmission of rotational motive power from the wheels, transmission of rotational motive power from the second blocking/connecting member to the first blocking/connecting member is connected. A second one-way clutch allows rotation of the third rotary element in the first predetermined rotational direction, and prevents rotation of the third rotary element in a direction opposite to the first predetermined rotational direction.

An all-wheel drive vehicle drivetrain can include an input member, first and second output members, a planetary differential, a first clutch, and a second clutch. The differential can include an internal gear, a carrier, a sun gear, and a differential gear set. The internal gear can be coupled to the input member to receive input torque about an axis. The carrier can be coupled to the first output for common rotation about the axis. The differential gear set can receive input torque from the internal gear and output differential torque to the carrier and the sun gear. The first clutch can be operable to selectively couple and decouple the sun gear with the second output member for common rotation. The second clutch can be operable to selectively transmit torque between the carrier and the second output member.

A vehicle drive unit that provides improved power transfer to a differential input member of a differential assembly. The vehicle drive unit is configured with an interlock system that is configured to inhibit the supply of electrical power from a source of electrical power if certain predetermined conditions are not met.

A drive unit system for an axle of an electric vehicle comprises: a first drive unit comprising a first rotor inside a first stator; a first transmission for a first wheel of the axle, the first transmission having a first input shaft coupled to a first gear having a first helix angle; a second transmission for a second wheel of the axle, the second transmission having a second input shaft coupled to a second gear having a second helix angle opposite to the first helix angle; and a coupling connecting the first and second input shafts to each other.

A hydraulic control unit (HCU) assembly, for an electro-hydraulic limited slip differential system for a vehicle, includes a support bracket configured to couple to an underbody of the vehicle in a location remote from a live axle assembly of the vehicle, and an HCU including an integrated accumulator and reservoir assembly, a control valve assembly, and a motor and hydraulic pump assembly. The HCU is coupled to the support bracket.

A clutch assembly includes a first clutch assembly having first clutch plates rotatably fixed to a first shaft and first carrier plates rotatably fixed to a clutch basket. The clutch assembly further includes a second clutch assembly having second clutch plates rotatably fixed to a second shaft and second carrier plates rotatably fixed to the clutch basket. The first and second clutch assemblies rotate about a common central axis and are actuated by a common actuator.

A family of axle assemblies that employ a modular concept to maximize part commonality amongst the several axle assemblies. The axle assemblies have a housing assembly that employs a main housing that is formed from a casting that is common to all of the axle assemblies.
