US Patent:

7837593, Nov 23, 2010

Filed:

Nov 12, 2007

Appl. No.:

11/938412

Inventors:

Andrew John Silveri - Royal Oak MI, US
Daniel Scott Colvin - Farmington Hills MI, US
Marvin Paul Kraska - Dearborn MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60W 10/02

US Classification:

477 5, 477 6

Abstract:

An automotive transmission transitions from a drive gear to a neutral gear when an engine is shutdown. During a rolling pull-up, a crankshaft of the engine will be spun up to a desired speed and the transmission will transition from the neutral gear to an appropriate gear based on a shift schedule. A target transmission input speed is commanded to be a synchronous speed plus an offset to smoothly transition out of electric axle drive propulsion.

Appl. No.:

12/498783

Inventors:

Daniel Scott Colvin - Farmington Hills MI, US
Walter Joseph Ortmann - Saline MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60W 10/08

US Classification:

180 65285, 180 6525, 60702, 123565

Abstract:

A powertrain for a vehicle having an air intake includes an engine and an electric machine. The engine includes a manifold configured to receive intake air entering through the vehicle air intake, and a throttle disposed between the air intake and the manifold. The powertrain also includes a compressor disposed between the air intake and the manifold, and operable to compress the intake air before it enters the engine. A pressure sensor disposed downstream of the compressor and upstream of the throttle provides air pressure signals to a control system that determines a driver demand and operates the electric machine to boost torque output of the powertrain when the driver demand requires operation of the compressor and the driver demand is not met by the engine. The torque boost of the electric machine is based at least in part on signals output from the pressure sensor.

International Classification:

B60W 10/08

US Classification:

477 5

Abstract:

A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine at the lowest engine speeds when the engine-required torque is the highest. This reduces the amount of torque necessary to be supplied from the motor/generator, and further helps to reduce torque disturbances in the driveline. If the motor/generator is producing torque to propel the vehicle at the time the engine start is requested, a launch clutch or one or more transmission clutches can be controlled to provide slip between the motor/generator and the vehicle drive wheels to further reduce torque disturbances in the driveline.

International Classification:

H02P 17/00

US Classification:

477 15

Abstract:

A system and method for controlling a hybrid electric vehicle during regenerative braking is provided. The system and method include a brake controller adapted to cause, for a selected transmission gear, a first torque ratio to be applied to a regenerative brake system during regenerative braking and a second torque ratio, different from the first torque ratio, to be applied when the vehicle is not regenerative braking. The first torque ratio results in an increased braking torque generated by the regenerative brake system compared with application of the second torque ratio.

International Classification:

G06F 19/00

US Classification:

701 67, 701 1, 701 36, 701 68

Abstract:

A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine upon an engine start request, thereby eliminating the need to transfer torque from the motor/generator to the engine. This helps to further reduce torque disturbances in the driveline when the engine is started.

US Classification:

701 67, 180 6521

Abstract:

A method for controlling a hybrid electric powertrain includes, in response to a request to increase a powertrain braking force on at least one of a plurality of traction wheels, (i) commanding at least one clutch to increase a gear ratio of a transmission, and (ii) during clutch stroke, commanding an electric machine to act as a generator such that the electric machine applies a braking force to at least one of the traction wheels.

US Classification:

701 22, 477 3, 180 65265

Abstract:

A control system and method for a hybrid electric vehicle powertrain supplies battery power boost torque to vehicle traction wheels to modify shift points for a multiple ratio transmission in the powertrain. A shift schedule is adjusted to avoid a downshift for small changes in torque demand, thus reducing shift frequency due to small transient changes in torque demand.
