Method for providing improved driveability for a vehicle

A method for controlling torque delivery in a vehicle powertrain using an enhanced limited operating strategy. The strategy is implemented when a powertrain controller fails to respond properly to a driver command for traction wheel torque whereby a modified wheel torque at vehicle traction wheels u...

Zusammenfassung:	A method for controlling torque delivery in a vehicle powertrain using an enhanced limited operating strategy. The strategy is implemented when a powertrain controller fails to respond properly to a driver command for traction wheel torque whereby a modified wheel torque at vehicle traction wheels under driver control is made available.
