Filed:

Aug 17, 2005

Appl. No.:

11/161803

Inventors:

Peter Barrette - Ann Arbor MI, US
John Glab - Riverview MI, US
Joseph Torres - Dearborn MI, US
John O'Rear - Whitmore Lake MI, US
Brian Hildreth - Plymouth MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60K 28/16

US Classification:

180197, 180247, 477181

Abstract:

A four wheel drive powertrain control for an automotive vehicle is disclosed. It includes a torque transfer case that distributes power from an engine-powered transfer case mainshaft to a secondary driving axle through a friction clutch as power is distributed directly from the engine-powered mainshaft to a primary driving axle. The friction clutch capacity is sufficient to mechanically lock the transfer case in a four wheel drive mode. If the clutch torque capacity is exceeded, a control algorithm will strategically ramp down engine torque requests by a powertrain controller to eliminate clutch slip.

US Classification:

475150, 475231, 475249

Abstract:

International Classification:

F16H 48/12

US Classification:

74650, 475231, 475249

Abstract:

A method for controlling a locking differential includes determining a temperature-dependent reference voltage at which a coil locks the differentia, determining an electric potential of a battery, using the battery to energize the coil and lock the differential, if the electric potential is equal to or greater than the reference voltage for a current temperature, and maintaining the differential unlocked, if the electric potential is less than the reference voltage.

International Classification:

G06F 19/00

US Classification:

701 88

Abstract:

A method for controlling a locking differential of a motor vehicle includes locking the differential, if vehicle speed is less than a reference speed, and a wheel speed differential due to wheel slip is greater than a reference speed; and unlocking the differential and preventing its engagement, if vehicle speed is greater than the reference speed, and said wheel speed differential is less than a reference speed.

International Classification:

B60W 30/188
B60L 15/20
B60K 7/00
B60W 10/08

Abstract:

A vehicle includes a first axle have a first electric machine, a second axle having a second electric machine and a controller. The controller is programmed to, in a user-selected four-wheel drive mode, command a first torque to the first electric machine based on a driver-demanded torque and a speed of the second axle, and command a second torque to the second electric machine based on a comparison of the driver-demanded torque and the first torque and further based on a speed of the first axle.

B60K 1/02
B60L 58/12
B60K 17/34
B60W 30/18

Abstract:

A vehicle with one-pedal driving mode includes a first axle having a first electric machine configured to power first wheels and a second axle having a second electric machine configured to power second wheels. A controller is programmed to, in response to a request for one-pedal driving mode, map pedal positions of the accelerator pedal to speeds of the first and second wheels such that each of the pedal positions corresponds to a driver-demanded speed of the first and second wheels, and control one or more of the electric machine so that the vehicle is propelled according to the driver-demanded speed.

Abstract:

A vehicle includes a primary axle powered by an actuator and a secondary axle powered by a motor. The secondary axle includes a differential, first and second halfshafs, first and second wheels, a first electric clutch selectively coupling the first wheel to the first halfshaft, and a second electric clutch selectively coupling the second wheel to the second halfshaft. A vehicle controller is programmed to: responsive to a request to activate the secondary axle and a first speed difference between the first and second wheels being less than a first threshold, engage the first and second clutches at a same time, and, in response to the request to activate the secondary axle and the first speed difference between the first and second wheels exceeding the first threshold, engage one of the clutches and then subsequently engage the other of the clutches once the one of the clutches is fully engaged.

International Classification:

B60L 15/20
F16H 63/32
H02K 7/116

Abstract:

Methods and system are described for changing a gear ratio of an axle gearbox that does not include friction clutches and that may or may not include synchronizers. The axle gearbox may receive propulsive force via an electric machine. The methods and systems permit the axle gearbox to be shifted from a high gear range to a low gear range while a vehicle that includes the axle gearbox is moving.
