  • Patent number: 9522582
    Abstract: A system for setting front axle load restoration for a load distributing trailer hitch that is used to hitch a trailer to a motor vehicle may include at least one sensor associated with a wheel of the motor vehicle. The system may further include at least one controller configured to receive signals from the at least one sensor to estimate one or more corner weights of the motor vehicle based on the signals. The at least one controller may be configured to calculate a load restoration that is required at a front axle of the motor vehicle to achieve a recommended load restoration based on the one or more estimated corner weights.

  • Patent number: 9199640
    Abstract: A vehicle includes a control system for reducing oversteer by controlling an electronic limited-slip differential (eLSD). The eLSD has one or more clutches configured to selectively distribute a controlled and varied amount of drive torque between a pair of wheels during a turn. At least one controller is programmed to operate the eLSD in (i) a tow-mode in response to the vehicle towing an object and (ii) a non-tow-mode in response to the vehicle not towing an object. When operated in the tow-mode, the eLSD is controlled by the controller to actively reduce a difference in speed between the wheels compared to when the eLSD is operating in the non-tow-mode or is not operated in the tow-mode.
