Abstract
The present invention provides a motor vehicle traction control system for providing on-demand four-wheel drive under certain tractive and operational conditions. The traction control system permits the vehicle operator to choose between operation in the conventional two-wheel drive and four-wheel drive mode or the "on-demand" four-wheel drive mode. Moreover, the traction control system is operable for disabling the on-demand four-wheel drive feature upon the vehicle operator subsequently shifting into either of the two-wheel drive and the four-wheel drive modes.
