  • Reducing oscillations in a motor vehicle driveline
    Patent number: 8095288
    Abstract: A method for reducing oscillations in a vehicle driveline includes transmitting torque to secondary wheels of the vehicle, determining a first rate of change in speed between the secondary wheels and primary wheels, if a second rate of change in speed between secondary wheels and primary wheels is greater than the first rate of change, reducing torque transmitted to the secondary wheels proportional to a ratio of the first rate of change and the second rate of change, and if the second rate of change is less than the first rate of change, using differential and proportional control to change said torque.
    Type: Grant
