US Patent:

7870925, Jan 18, 2011
Filed:

Feb 21, 2006
Appl. No.:

11/276256
Inventors:

Andreas E. Perakes - Canton MI, US
Ashok Rodrigues - Farmington Hills MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

B60K 17/356
US Classification:

180243, 180 625, 180 6285
Abstract:

A system and method for managing a powertrain in a vehicle determines a number of vehicle conditions, and compares them to predetermined conditions to determine whether a secondary axle of the vehicle should be automatically connected to or disconnected from the powertrain. In general, if the speed of the vehicle is above some predetermined speed threshold, the secondary axle is disengaged to increase fuel economy. Conversely, if the speed of the vehicle is below some predetermined threshold, the secondary axle is typically engaged to help maximize the capture of regenerative braking energy during a braking event. Additional vehicle conditions may be examined, and exceptions to the general rule utilized, to further enhance the control strategy.

International Classification:

B60W 10/02
B60W 10/04
F16H 59/00
US Classification:

477 35, 477 98, 477180
Abstract:

A method for controlling a vehicle drivetrain includes de-energizing a clutch that connects a differential output to a wheel, rotating said component through a sump by pulsing the clutch when a speed of a differential component is less than a reference speed, and cyclically pulsing the clutch while a speed of said component exceeds the reference speed and a count of a timer, started when the clutch is de-energized, exceeds a reference count.
