Patent ID: 7322436

Claim:
A transfer case assembly comprising: an input shaft adapted to be coupled to a power source; a first axle output shaft driven by said input shaft; a second axle output shaft selectively driven by said input shaft; a clutch mechanism for coupling said second axle output shaft to said first axle output shaft; and a controller for controlling activation of said clutch mechanism wherein said controller compares rotational speeds of said first and second axle output shafts to each other, generates a control signal to bring said rotational speeds of said first and second axle output shafts within a common rotational speed range if rotational speeds of said first and second axle output shafts differ from each other by a predetermined amount, and activates said clutch mechanism to couple said first and second axle output shafts together during a wheel slippage condition when rotational speeds of said first and second axle output shafts are within said common rotational speed range.
