Abstract
The invention provides a method of progressive engagement of all-wheel drive for a mobile vehicle. A set of vehicle parameters is sensed, and an all-wheel drive lock value is determined based on the sensed set of vehicle parameters. Vehicle subsystem control activation is determined, and the all-wheel drive lock value is adjusted based on the vehicle subsystem control activation determination. An all-wheel drive controller is engaged based on the adjusted all-wheel drive lock value.
