System for mitigating vehicle sway

A vehicle controller comprising:

• input channels configured to receive signals indicative of yaw rates;
• output channels configured to provide commands to adjust friction brake and differential lockup clutch torques to counteract yaw rates;
• and
• control logic programmed to,
• in response to a difference between desired and actual yaw rates exceeding a first threshold, increase lockup clutch torque, and
• in response to the difference exceeding a second threshold that is greater than the first threshold, decrease lockup clutch torque and increase friction brake torque.

A vehicle comprising:

• a steering wheel;
• friction brakes;
• an axle having an electronic limited-slip differential including a lockup clutch;
• and
• a controller programmed to, in response to a yaw rate in an absence of steering wheel input, increase lockup clutch torque to counteract the yaw rate when the yaw rate exceeds a first threshold threshold, decrease lockup clutch torque when the yaw rate exceeds a second threshold that is greater than the first threshold, and increase friction brake torque to counteract the yaw rate when the yaw rate exceeds the second threshold.
