Zusammenfassung:Methods and apparatus are provided for generating a slip control for an active driveline device (such as an electronic limited slip differential (eLSD)) that corrects for longitudinal tire slip in the turning wheels of a vehicle. Indicia of a yaw rate of the vehicle are obtained by the eLSD, which then determining a target velocity difference for the turning wheels based at least in upon the yaw rate, along with other factors such as difference in wheel rotation speed or the wheel-road angle of the vehicle. Using these measured parameters, a slip control signal can be applied to the eLSD as a function of the determined target velocity difference.
