A system averts catastrophic folding of an articulated vehicle e.g. jack-knifing a tractor against its attached trailer when tires have lost adhesion to a road surface. The apparatus includes independent port and starboard AC motor controllers that convert DC power to AC phases and magnitudes. A battery is regeneratively charged during normal braking operation of the vehicle and discharged when the AC motors apply torque to wheels. Sensors determine when the AC motor controllers provide phases and magnitudes that result in a positive torque to one or more motors and a negative torque to a different one or more motors. The apparatus operates by generating a horizontal yaw force on the trailer in opposition to closing the angle between the tractor and the trailer; by applying a rotational force on the fifth wheel; and by unbalanced torque applied to the tractor's port and starboard driven wheels.
