Driveline assembly including torque vectoring system

A method for operating a driveline assembly for a vehicle, the method including:

• identifying a torque vectoring event for a first wheel output during a low range drive operation with a controller;
• shifting a center clutch of a differential from an unlocked position to a locked position during the torque vectoring event, wherein a first primary shaft and a second primary shaft are coupled to the differential and able to rotate at different speeds than one another while the center clutch is in the unlocked position, and wherein the first and second primary shafts are fixed for rotation at the same speed as one another while the center clutch is in the locked position;
• and
• shifting a first upshift clutch of a first reducer that is coupled to the first primary shaft from a contact position toward released position during the torque vectoring event, wherein the first upshift clutch fixes the first primary axle to a first wheel output in the contact position to provide a high speed and low torque output to the first wheel output while in the contact position, and wherein the first upshift clutch provides a gear reduction between the first primary axle and the first wheel output in the released position to provide a low speed and high torque output to the first wheel output while in the released position.

A method for operating a driveline assembly for a vehicle, the method including:

• identifying a torque vectoring event for a first wheel output during a high range drive operation with a controller;
• shifting a center clutch of a differential from an unlocked position to a locked position during the torque vectoring event, wherein a first primary shaft and a second primary shaft are coupled to the differential are able to rotate at different speeds than one another while the center clutch is in the unlocked position, and wherein the first and second primary shafts are fixed for rotation at the same speed as one another while the center clutch is in the locked position;
• shifting a second upshift clutch of a second reducer that is coupled to the second primary shaft from a contact position into a released position while shifting the center clutch to the locked position, wherein the second upshift clutch fixes the second primary axle to a second wheel output in the contact position to provide a high speed and low torque output to the second wheel output while in the contact position, and wherein the second upshift clutch provides a gear reduction between the second primary axle and the first wheel output in the released position to provide a low speed and high torque output to the second wheel output while in the released position;
• increasing torque to an output shaft of an electric motor, wherein the output shaft of the electric motor is rotationally connected to a first wheel output and a second wheel output, and wherein the torque is increased to a level required by the first wheel output to overcome the torque vectoring event;
• modulating a first upshift clutch of a first reducer that is coupled to the first primary shaft from a contact position into a released position, wherein the first upshift clutch directly fixes the first primary axle to a first wheel output in the contact position to provide a high speed and low torque output to the first wheel output while in the contact position, and wherein the first upshift clutch provides a gear reduction between the first primary axle and the first wheel output in the released position to provide a low speed and high torque output to the first wheel output while in the released position;
• shifting the second upshift clutch into the contact position and shifting the center clutch into the unlocked position after the torque event is over.
