Modern traction control systems typically rely on friction in the form of brakes, clutches, or built-in torque bias ratios in order to mitigate wheel slip. However, under certain conditions, traction control systems may not be able to apply sufficient friction to control a suddenly slipping wheel. In addition, they may not respond fast enough to prevent the vehicle from losing its forward momentum. For these reasons, locking differentials, or lockers are generally preferred by off-roading enthusiasts. However, the operation of lockers requires special knowledge and can lead to rapid tire wear or driveline damage if left engaged.

The SPARC DRIVE™ differential system presented here solves all of the above issues by precisely governing an allowable differential rate at all ...
