A system and method to prevent torque to be applied to the vehicle wheels in a direction opposite the vehicle's movement should the electric traction motor of the hybrid vehicle fail in such a way that rotation of the rotor with respect to the stator is prevented or hindered is described herein. The system includes two traction power sources can be used in parallel to power the wheels of the vehicle. Accordingly, should such an unwanted torque be detected from one of the traction power source, the other traction power source is energized and so controlled as to apply a compensating torque to cause the wheels to be freewheeling and therefore allow the driver to exit the road safely.
