view source
US Patent:

6363316, Mar 26, 2002
Filed:

Aug 21, 2000
Appl. No.:

09/642958
Inventors:

Ihab S. Soliman - Dearborn MI
Jerry Dean Robichaux - Tuscon AZ
Tobias John Pallett - Ypsilanti MI
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
International Classification:

G06F 1548
US Classification:

701104, 123399, 123480
Abstract:

A system and method for controlling an internal combustion engine to improve air/fuel ratio control particularly during transient operating modes include estimating cylinder air charge during a future fuel injection event. The system and method use a dynamic airflow actuator position model to determine future actuator position which is then used by an airflow model and manifold filling model to provide the estimated future cylinder air charge. The system and method use observer-based and adaptive control to compensate for modeling errors and sensor dynamics while assuring stability and accurate prediction of airflow actuator position and airflow.

US Patent:

6442455, Aug 27, 2002
Filed:

Dec 21, 2000
Appl. No.:

09/746492
Inventors:

Stephen John Kotre - Ann Arbor MI
Jerry D. Robichaux - Tucson AZ
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
International Classification:

B60L 1100
US Classification:

701 22, 701 1, 701 86, 701 84, 701 85, 701 83, 701109, 701101, 701102, 701112, 701103, 701104, 12317916, 12317918, 123195 G, 1231922, 123198 F, 1231793, 123673, 123681, 123674, 123698, 123575, 123478, 180 652, 180 654, 180 658, 180 653, 290 16, 290 40 C, 322 16, 322 22
Abstract:

This invention is a method and system for a hybrid electric vehicle adaptive fuel strategy to quickly mature an adaptive fuel table. The strategy adaptively alters the amount of fuel delivered to an internal combustion engine to optimize engine efficiency and emissions using engine sensors. Before the adaptive fuel strategy is permitted, an engine âonâ idle arbitration logic requires the HEV to be in idle conditions, with normal battery state of charge, normal vacuum in the climate control and brake system reservoir; and, the vapor canister not needing purging. The strategy orders the engine throttle to sweep different airflow regions of the engine to adapt cells within the adaptive fuel table. In the preferred configuration, a generator attached to the vehicle drive train, adds and subtracts torque to maintain constant engine speed during the throttle sweeps.

US Patent:

6453666, Sep 24, 2002
Filed:

Jun 19, 2001
Appl. No.:

09/884241
Inventors:

Gopichandra Surnilla - West Bloomfield MI
Jeffrey Scott Hepburn - Birmingham MI
Jerry D. Robichaux - Tucson AZ
Michael John Cullen - Northville MI
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
International Classification:

F01N 300
US Classification:

60285, 60274, 60295, 60297
Abstract:

A method and system for operating a lean-burn internal combustion engine in cooperation with an exhaust gas purification system having an emission control device, wherein the system includes a controller which calculates current levels of a selected exhaust gas constituent, such as NO , during lean engine operating conditions based upon the difference between a determined instantaneous feedgas NO concentration and a determined instantaneous device efficiency. The controller discontinues lean engine operation when the tailpipe NO , expressed in terms of either grams-per-mile or grams-per-hour, exceeds a predetermined threshold level, either instantaneously or as averaged over the course of a device purge-fill cycle.

US Patent:

6490511, Dec 3, 2002
Filed:

Nov 10, 2000
Appl. No.:

09/709612
Inventors:

Abbas Raftari - Northville MI
Deepa Ramaswamy - Ypsilanti MI
Jerry D. Robichaux - Tucson AZ
Assignee:

Ford Motor Company - Dearborn MI
International Classification:

B60L 300
US Classification:

701 22, 180 651, 180 653, 290 9, 290 40 C, 318140, 322 39
Abstract:

A torque based monitor method, apparatus, and system, for a torque splitting hybrid electric vehicle (HEV) powertrain and regenerative brake system. The preferred powertrain configuration includes an internal combustion engine , generator , and electric traction motor combined to produce the vehicles output shaft torque. The invention has a set of vehicle state sensors and communication interfaces connected independently to a main controller and an independent plausibility check (IPC). The IPC monitors and mitigates the powertrain output shaft torque (OST) by reducing powertrain torque when the detected OST is greater than the desired OST. The IPC has a second mode of operation to shut down the powertrain OST of the HEV powertrain when a fault or failure is detected. Additional features include a quizzer function to continuously verify the functionality of the IPC.

Appl. No.:

09/650315
Inventors:

Jerry D. Robichaux - Tucson AZ
Diana Dawn Brehob - Dearborn MI
John D. Russell - Farmington Hills MI
Thomas George Leone - Dearborn MI
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
International Classification:

F02D 700
US Classification:

123399, 123432, 123 9015
Abstract:

Based on demanded engine torque, engine speed and transition type, throttle position and closing time of a randomly operable intake valve are determined such that a smooth transition can be accomplished.

Canister Purge Strategy For A Hybrid Electric Vehicle

US Patent:

6557534, May 6, 2003
Filed:

Jan 3, 2001
Appl. No.:

09/753388
Inventors:

Jerry D. Robichaux - Tucson AZ
Stephen John Kotre - Ann Arbor MI
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
International Classification:

F02M 3302
US Classification:

123520, 12317916
Abstract:

The present invention provides a method and system for purging a vapor canister in a Hybrid Electric Vehicle during vehicle idle conditions. The present invention first determines whether purging is necessary by measuring fuel tank pressure and the time since the last purge. If either of these elements exceeds a calibratable threshold, the controller determines that the engine needs to be on and that purging must occur. An electronic throttle controller can also be used to command the throttle plate to low positions to increase intake manifold vacuum while purging. This allows for very rapid ingestion of the fuel vapor without risk of engine stalls, if used in an HEV where the engine speed is controlled by an electric motor. Upon completion of the purging process, the engine is shut âoffâ and the vehicle is returned to its normal idle conditions.
