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.

Inventors:

Daniel Scott Colvin - Farmington Hills MI, US
Bernard D. Nefcy - Novi MI, US
Marvin Paul Kraska - Dearborn MI, US
Walter Joseph Ortmann - Saline MI, US

Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI

International Classification:

B60W 10/02
B60W 20/00

US Classification:

192 358, 180 65265

Abstract:

A vehicle includes a motive power source, a transmission, and a clutch system. The vehicle further includes a controller that causes the clutch system to generate a generally constant clutch pressure to mechanically couple the motive power source and transmission as a line pressure associated with the transmission varies.

International Classification:

B60W 10/08

US Classification:

477 5

Abstract:

A control system including a method and apparatus for operating a hybrid vehicle. A disconnect clutch selectively separates an electric machine from a combustion engine. If a wide open throttle or high torque command is requested and the combustion engine is shut down, a 12 volt starter may be used to start the combustion engine while disconnected from the electric machine and all of the electric machine torque available may be used for traction.

International Classification:

F16D 48/02
B60W 20/00

US Classification:

477 5, 192 8563, 180 65275, 903902

Abstract:

A system and method for controlling a vehicle having an electric traction motor coupled to a transmission by a clutch include modifying torque transmitted to the driveline by modifying the clutch apply pressure in response to a difference between rotational speed of a driveline component and a filtered rotational speed of the driveline component to reduce driveline oscillation when the clutch is unlocked. The clutch pressure may be modified in response to a vehicle event that may otherwise induce driveline oscillations, such as a transmission ratio change or regenerative braking, for example.

International Classification:

B60W 20/00
B60W 10/06

US Classification:

701 22, 903902, 180 6528

Abstract:

A hybrid vehicle has an engine, an electric machine connected to the engine by an upstream clutch, a transmission gearbox connected to the electric machine by a downstream clutch, and a controller. The controller is configured to start the engine using one of a plurality of start sequences that control the electric machine, the upstream and downstream clutches. The engine start sequence is selected based on transmission gearbox input speed and a driver demand input. A method of controlling a hybrid vehicle is provided. An engine is selectively coupled to an electric machine by an upstream clutch with the electric machine selectively coupled to a transmission gearbox by a downstream clutch. The engine is started using a control sequence to control the electric machine, upstream clutch, and downstream clutch. The control sequence is determined by a vehicle state based on transmission gearbox input speed and a driver demand input.
