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.

A technique for providing better detection of close range truck trailers for a motor vehicle with Stop and Go Adaptive Cruise Control determines if a range parameter to a target requires modification if such target is a truck trailer, for example. Truck trailer geometry is such that a standard adaptive cruise control system may have difficulty accurately determining the range to the rearmost position of the truck. The technique determines an initial range from the motor vehicle to a target. Then, the technique determines whether the range rate of the target is above a predetermined rate. When the range rate of the target is not above the predetermined rate, the technique determines whether the initial range to the target is less than a current range to the target. If so, the technique provides an adjusted range, which is then utilized in the control operation of the motor vehicle.
