US Patent:

57323828, Mar 24, 1998
Filed:

Nov 6, 1996
Appl. No.:

8/744258
Inventors:

Gintaras Vincent Puskorius - Novi MI
Lee Albert Feldkamp - Plymouth MI
Kenneth Andrew Marko - Ann Arbor MI
John Victor James - Walled Lake MI
Timothy Mark Feldkamp - Ann Arbor MI
Assignee:

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

F02D 1500
G01M 1500
US Classification:

701110
Abstract:

A method for identifying engine combustion failure of an internal combustion engine having a plurality of cylinders, a crankshaft and a crankshaft position sensor includes the steps of operating the internal combustion engine to rotate the crankshaft, measuring rotational quantities of the crankshaft corresponding to events created by each of the plurality of cylinders during operation of the internal combustion engine, correcting the rotational quantities measured to remove periodic position irregularities to generate a corrected temporal signal, generating an acceleration signal of the crankshaft using the corrected temporal signals, and identifying combustion failures as a function of the acceleration signal. A time-lagged recurrent neural network utilizes the acceleration signal, along with other engine parameters to identify the cylinder-specific misfire events.

US Patent:

53056353, Apr 26, 1994
Filed:

Apr 2, 1993
Appl. No.:

8/042257
Inventors:

John V. James - Walled Lake MI
Nathan R. Soderborg - Ann Arbor MI
Timothy M. Feldkamp - Ann Arbor MI
Assignee:

Ford Motor Company - Dearborn MI
International Classification:

G01M 1500
US Classification:

73116
Abstract:

System and method for filtering a misfire data stream having numerical values that indicate whether a firing of a cylinder was a misfire or a proper firing, to yield an optimum measurement misfire-rate for accurate and rapid determination of whether an engine is misfiring beyond a threshold level. The method includes measuring firings of the cylinder during operation of the engine to produce measured cylinder firing signals, processing the measured cylinder firing signals received to produce a current misfire detection data stream of first and second logic signals, wherein the first logic signals indicate a current misfire condition and the second logic signals indicate a current normal firing of the engine, combining the current misfire detection data stream with previously detected and stored measured data representing an engine misfire rate, replacing the previously stored measured data by the combined current and previously stored data to produce a misfire rate output measurement, storing threshold values, comparing the combined current and previously stored data and the stored threshold values, generating an actuation signal if the combined current and previously stored data signal exceeds the stored threshold values, and indicating a misfire condition in the engine upon receiving the actuation signal.

US Patent:

53947444, Mar 7, 1995
Filed:

Jan 5, 1994
Appl. No.:

8/177498
Inventors:

John V. James - Walled Lake MI
Timothy M. Feldkamp - Ann Arbor MI
Assignee:

Ford Motor Company - Dearborn MI
International Classification:

G01M 1500
US Classification:

731173
Abstract:

The time needed to verify proper operation of a fault detection system or to verify the impact of the replacement of a component in the system being monitored is reduced without substantial increase in the possibility of false indication of failure or false indication of proper operation by employing a geometric moving average with a variable time constant reset to a minimum value upon initialization and gradually increasing to a maximum value. Motor vehicle systems and components are monitored and a diagnostic indicator annunciates faults to alert the vehicle operator to malfunctions.

Method Of Generation Correction Tables For Misfire Detection Using Neural Networks

US Patent:

57748233, Jun 30, 1998
Filed:

Sep 4, 1997
Appl. No.:

8/923670
Inventors:

John Victor James - Walled Lake MI
Timothy Mark Feldkamp - Ann Arbor MI
Kenneth Andrew Marko - Ann Arbor MI
Lee Albert Feldkamp - Plymouth MI
Gintaras Vincent Puskorius - Novi MI
Assignee:

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

G01M 1500
US Classification:

701110
Abstract:

A method of automating the calibration of lookup tables containing correction values to be used in an on-board vehicle system is disclosed. The method includes training a neural network to model engine behavior by outputting cylinder specific crankshaft acceleration correction values in response to any engine speed and load input conditions. The correction values generated are stored in a memory device. The training takes place off-board the vehicle, using a data set previously obtained from operating a representative engine under normal operating conditions.

Misfire Detection In Internal Combustion Engine With Overlapping Power Strokes
view source
US Patent:

53657802, Nov 22, 1994
Filed:

Dec 27, 1993
Appl. No.:

8/173029
Inventors:

Timothy M. Feldkamp - Ann Arbor MI
Assignee:

Ford Motor Company - Dearborn MI
International Classification:

G01M 1500
US Classification:

731173
Abstract:

Incorrect classifications of misfires (potential false alarms) are reduced by comparing the power loss value for a particular cylinder event with the power loss values for neighboring cylinder events. A set of rules for the comparisons permits identifications of potential misfires that are, in reality, a normally firing cylinder event having a measurement that is altered by a neighboring misfire event, referred to as the pulling effect. The invention improves misfire detection accuracy, especially in internal combustion engines with 8 or more cylinders, which have substantially overlapping power strokes.
