Carol Louise Okubo - Belleville MI
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
G06F 1900
US Classification:
701110, 123399, 701114, 701102

A control signal, , to the electronically controlled throttle is provided, such provided control signal being a function of: a previously provided control signal to the electronically controlled throttle, ; an offset, , of the previously provided control signal, , from the determined driver demanded torque, - ; and the determined time rate of change d( )/dt.

Idle Speed Control Method And System

US Patent:
6820589, Nov 23, 2004
Filed:
Oct 17, 2002
Appl. No.:
10/273206
Inventors:
Carol Louise Okubo - Belleville MI
John Ottavio Michelini - Sterling Heights MI
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F02D 4100
US Classification:
12333919, 1233391, 12333914, 12333921
Abstract:
A method and system for generating an idle control signal for an internal combustion engine is disclosed. Rotational speed, n, of the engine is measured. Combustion generated torque is estimated as a function of the measured engine rotational speed, n. The idle control signal for the engine is produced as a function of the difference between: (A) a time rate of change in such measured engine rotational speed, dn/dt, and; (B) the sum of the estimated combustion generated torque and a function of an engine idle speed error. The idle speed error is representative of the difference between an idle speed set point and the measured rotational speed, n. Thus, idle speed control is achieved using only a feedback system which responds to measured operating conditions of the engine rather than with a combination of feedback and a feedforward model which relies on a model of each individual engine loss or load to calculate the resulting impact on the engine.

US Patent:
7085631, Aug 1, 2006
Filed:
Jul 29, 2004
Appl. No.:
10/710715
Inventors:
Ryan McGee - Ann Arbor MI, US
Chris Kapolnek - Dearborn MI, US
Paul Gartner - Dearborn MI, US
Carol Okubo - Belleville MI, US
Paul Niessen - Plymouth MI, US
Waheed Alashe - Northville MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
B60L 9/00
US Classification:
701 22, 180 654, 180 658, 477 2
Abstract:
A vehicle and method are provided that determine a misfire torque limit for an engine in the vehicle. The vehicle includes an electric machine operable to provide torque to the engine. The method includes commanding the engine to operate at a predetermined torque and a predetermined speed, thereby putting the engine in an idle state. An output torque of the engine is then determined while the engine is in the idle state. A torque offset, defined as the difference between the torque command and the determined engine output torque, is also determined. The misfire torque limit for the engine is then determined based at least in part on the torque offset.

US Patent:
7198588, Apr 3, 2007
Filed:
Jun 11, 2003
Appl. No.:
10/250193
Inventors:
Ryan Abraham McGee - Ann Arbor MI, US
Christopher John Teslak - Plymouth MI, US
Carol Louise Okubo - Belleville MI, US
Assignee:
Ford Global Technologies, LLC. - Dearborn MI
International Classification:
B60K 1/02
US Classification:
477 3, 477114, 475 5, 180 652
Abstract:
A method for controlling engine idle in a vehicle having a motor connected to the engine through a power transfer unit is provide. Upon receiving a neutral command, the engine torque is commanded to approximately zero. The motor torque is adjusted to maintain an approximately constant engine speed as the engine torque is reduced. The torque from the engine transferred to the vehicle wheels is at or near zero. When the torque at the vehicle wheels is non-zero, a second motor is used to cancel the torque output from the engine so the torque at vehicle wheels is zero. When the engine torque has reached approximately zero, or when a predetermined amount of time has past, both motors are shutdown, and all of the remaining engine torque is transferred to the first motor through the power transfer unit.

US Patent:
7204230, Apr 17, 2007
Filed:
Jun 1, 2005
Appl. No.:
10/908937
Inventors:
David Bevan - Northville MI, US
Carol Okubo - Belleville MI, US
Douglas Martin - Canton MI, US
Kenneth Miller - Canton MI, US
Edward Badillo - Canton MI, US
Matt Smith - Dearborn Heights MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F02D 41/00
F01M 5/00
US Classification:
123350, 123196 AB
Abstract:
A vehicle and method for controlling an engine in a vehicle are provided. A temperature of a lubricating fluid in the engine is determined, as are first and second engine speed limits. Operation of the engine at the first engine speed limit is limited to a predetermined time period when the lubricating fluid temperature is between first and second predetermined temperatures. The engine speed is at least temporarily limited to the second engine speed limit after the engine has been operated at the first engine speed limit for the predetermined time period and the lubricating fluid temperature is between the first and second predetermined temperatures.

The engine torque command is initialized to a percentage of a target engine torque as a function of variables that may include a smoothness factor.

Torque-Based Powertrain Control For Vehicles

US Patent:
7275518, Oct 2, 2007
Filed:
Apr 28, 2006
Appl. No.:
11/380793
Inventors:
Paul Gartner - Dearborn MI, US
Douglas Martin - Canton MI, US
Ryan McGee - Ann Arbor MI, US
Chris Kapolnek - Dearborn MI, US
Carol Okubo - Belleville MI, US
Kenneth Miller - Canton MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F02P 5/14
US Classification:
12340623, 12340655
Abstract:
A system and method for controlling a vehicle powertrain having an internal combustion engine include determining a difference between a desired engine torque and a current engine torque, adjusting the difference based on a stored torque offset corresponding to a current engine speed, and controlling the engine to produce a torque corresponding to the adjusted torque difference. The stored torque offset is adjusted when the engine is operating in a predetermined engine speed range based on a steady-state difference between the desired and current engine torque to reduce the steady-state difference to zero. The adjusted torque difference may be limited by a maximum-engine-torque-available parameter and a minimum-engine-torque-available parameter, which is based on an operating temperature, such as the engine coolant temperature. The system and method may also include controlling spark to rapidly reduce current engine torque to the adjusted torque difference value.

10/906784
Inventors:
Kenneth Miller - Canton MI, US
Paul Gartner - Dearborn MI, US
Carol Okubo - Belleville MI, US
Douglas Martin - Canton MI, US
Edward Badillo - Canton MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
B60L 9/00
US Classification:
701 22, 701 84, 701101, 477 2
Abstract:
A control method is disclosed for maintaining a calibrated minimum load for an engine in a vehicle powertrain with an engine. The possibility of engine misfire due to low engine loads is reduced. Further, undesired high temperature of an engine exhaust gas catalytic converter due to prolonged operation of the powertrain at low engine loads is avoided.
