The present invention involves a primary electric assist with a secondary fall back steering assist in the case of failures of the primary steering system. The primary and fall back systems can be steering column or steering rack based or any combination of these two options. The secondary steering assist system is a low cost design that ensures the steering torque levels will not exceed predetermined values. The secondary electric steering assist will usually deliver less than 50% of the assistance that is provided by the primary steering assistance system. This level of assistance by the secondary system is sufficient to provide for safe operation of the vehicle.
