Abstract
A vehicle includes friction brakes, an axle, and a controller. The axle has an electronic limited-slip differential that includes a variable torque capacity lockup clutch. The controller is programmed to, in response to a difference between desired and actual yaw rates exceeding a first threshold, increase the torque of the lockup clutch to decrease the difference between the desired and actual yaw rates. The controller is further programmed to, in response the difference between desired and actual yaw rates exceeding a second threshold that is greater than the first threshold, increase the torque of the friction brakes to decrease the difference between the desired and actual yaw rates.
