Abstract

A vehicle includes multiple wheels, a locking drive differential, and a stability controller. A first wheel is mechanically coupled to a second wheel. The locking drive differential mechanically couples the second wheel to a third wheel. The stability controller is coupled to the third wheel. The stability controller is programmed to attain a slip rate of about the first and the second wheel at the third wheel, which stabilizes the vehicle in an over-steer condition. The method applies a modulated stability pressure to the third wheel until the third wheel attains about the combined slip rate of the first wheel and the second wheel and a fourth wheel is rotating at about the velocity of the vehicle.
