CONTROL OF ELECTRONIC LIMITED SLIP DIFFERENTIAL WHILE TOWING
First Claim
1. A system for reducing oversteer in a vehicle comprising:
- an electronic limited-slip differential (eLSD) having a clutch pack actuated by a clutch pressure to alter an amount of driving force transmitted amongst a pair of wheels during a turn; and
at least one controller 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.

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.

8. A method of controlling an electric limited-slip differential (eLSD) in a vehicle, the method comprising:
-
operating the eLSD in a tow-mode in response to the vehicle towing; and providing a clutch pressure in a clutch in the eLSD to a first amount in response to operating in the tow-mode during a given turn, wherein the first amount is different than a second amount of clutch pressure provided in the clutch in an absence of the tow-mode for the given turn. - View Dependent Claims (9, 10, 11, 12)

13. A vehicle comprising:
-
an electronic limited-slip differential (eLSD) mechanically coupling wheels of the vehicle; and a controller programmed to distribute drive torque between the wheels via the eLSD according to an in-tow force acting upon a rear of the vehicle during a turn of the vehicle. - View Dependent Claims (14, 15, 16, 17, 18, 19)
