ABSTRACT:
Methods and apparatus are provided for integrating a torque vectoring differential (TVD) and a stability control system in a motor vehicle. The integrated system is utilized for more efficiently correcting understeer and/or oversteer slides in a motor vehicle. In correcting these slides, the integrated system utilizes the TVD to rotate two wheels on opposite sides of the motor vehicle at different rates to create a yaw moment at the vehicle's center of gravity until the TVD reaches a saturation point and the understeer or oversteer slide is not corrected. Once the saturation point is reached without correcting the understeer or oversteer slide, the stability control system is employed to selectively apply one or more of the vehicle's brakes in a further effort to correct the understeer or oversteer slide.
