Us Patents

Encoded Crank Position Sensor

US Patent:
6752009, Jun 22, 2004
Filed:
Aug 3, 2001
Appl. No.:
09/921438
Inventors:
Timothy L. Minich - South Lyon MI
David Stewart Mathews - Howell MI
Assignee:
General Motors Corporation - Detroit MI
International Classification:
G01M 1500
US Classification:
731173
Abstract:
A target wheel for providing timing information for a crankshaft in an internal combustion engine, the target wheel comprising a substantially circular member having a plurality of teeth, the teeth having variable widths, and the teeth having rising edges distributed in a non-uniform fashion and falling edges distributed in a uniform fashion, where the target wheel provides speed and timing information for multiple internal combustion engine configurations.

Cylinder Torque Balancing For Internal Combustion Engines

US Patent:
7500470, Mar 10, 2009
Filed:
May 11, 2006
Appl. No.:
11/432446
Inventors:
Kenneth J. Buslepp - Brighton MI, US
Douglas R. Verner - Sterling Heights MI, US
Randall J. Guild - Okemos MI, US
David S. Mathews - Howell MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
F02D 41/14
US Classification:
123436, 123673
Abstract:
An engine torque control system for balancing torque output across cylinders of an internal combustion engine includes a first module that determines a derivative term for each cylinder of the engine based on rotation of a crankshaft. A second module determines a torque correction for a first cylinder based on an average derivative term associated with the first cylinder. The second module adjusts a torque output of the first cylinder based on the torque correction and adjusts a torque output of a second cylinder based on the torque correction.

Method And System For Collecting Crankshaft Position Data

US Patent:
7610800, Nov 3, 2009
Filed:
Aug 29, 2007
Appl. No.:
11/847109
Inventors:
Xuan Dung T. Avallone - Milford MI, US
John L. Lahti - Novi MI, US
David S. Mathews - Howell MI, US
Leonard G. Wozniak - Ann Arbor MI, US
William R. Cawthorne - Milford MI, US
Robert S Wickman - Westland MI, US
Assignee:
GM Global Technology Operations, Inc. - Detroit MI
International Classification:
G01M 15/06
US Classification:
7311426
Abstract:
A method for collecting crankshaft position data includes rotating a crankshaft of an engine within a selected angular velocity range without any fuel being applied to the engine and measuring crankshaft position data.

Cylinder Torque Balancing For Internal Combustion Engines

US Patent:
7654248, Feb 2, 2010
Filed:
Feb 7, 2008
Appl. No.:
12/027532
Inventors:
Kenneth J. Buslepp - Brighton MI, US
Douglas R. Verner - Sterling Heights MI, US
Randall J. Guild - Okemos MI, US
David S. Mathews - Howell MI, US
Todd R. Shupe - Milford MI, US
Robert Douglas Shafto - New Hudson MI, US
Kevin C. Wong - Ann Arbor MI, US
Karen A. Blandino - Fenton MI, US
International Classification:
F02D 41/14
US Classification:
123436, 123673
Abstract:
An engine torque control module comprises a derivative module and a cylinder torque module. The derivative module determines a derivative term for a first cylinder of an internal combustion engine based on rotation of a crankshaft and determines an average derivative term for the first cylinder based upon the derivative term. The cylinder torque module determines an operating condition of the first cylinder based on the average derivative term, adjusts a torque output of the first cylinder based on the operating condition, and adjusts a torque output of a second cylinder based on the operating condition.

Cylinder Pressure Sensor Diagnostic System And Method

US Patent:
7726281, Jun 1, 2010
Filed:
Oct 14, 2008
Appl. No.:
12/250956
Inventors:
Kenneth J. Buslepp - Brighton MI, US
Douglas R. Verner - Sterling Heights MI, US
Joseph R. Dulzo - Novi MI, US
David S. Mathews - Howell MI, US
International Classification:
F02P 5/00
F02M 7/00
G01L 15/00
US Classification:
12340622, 12340623, 123435, 7311411, 7311416
Abstract:
A control module comprising a cylinder torque determination module that determines an indicated torque for a cylinder in an engine based on a pressure in the cylinder, a cylinder torque balancing module that determines a derivative term for the cylinder based on rotation of a crankshaft, and a cylinder pressure error detection module that detects a pressure error for the cylinder based on the indicated torque and the derivative term. A method comprising determining an indicated torque for a cylinder in an engine based on a pressure in the cylinder, determining a derivative term for the cylinder based on rotation of a crankshaft, and detecting a pressure error for the cylinder based on the indicated torque and the derivative term.

Method And Control System For Controlling An Engine Function Based On Crankshaft Acceleration

US Patent:
7918212, Apr 5, 2011
Filed:
Jun 4, 2009
Appl. No.:
12/478159
Inventors:
Julian R. Verdejo - Farmington MI, US
Michael R. Grimes - Saline MI, US
Nicholas John Kalweit - Novi MI, US
David S. Mathews - Howell MI, US
International Classification:
F02D 41/10
US Classification:
123492, 12340625, 12340646, 1234065, 701110
Abstract:
A method and control system for controlling an engine includes an instantaneous crankshaft acceleration determining module determining an instantaneous crankshaft acceleration. An engine parameter adjustment module adjusts an engine parameter in response to the instantaneous crankshaft acceleration.

Pattern Recognition For Random Misfire

US Patent:
8027782, Sep 27, 2011
Filed:
Sep 16, 2009
Appl. No.:
12/560739
Inventors:
Tameem K. Assaf - Milford MI, US
David S. Mathews - Howell MI, US
John V Bowman - Farmington MI, US
Sanjeev M. Naik - Troy MI, US
International Classification:
F02D 41/10
US Classification:
701111, 1234065, 123436
Abstract:
A control system includes a jerk determination module and a misfire confirmation module. The jerk determination module determines a jerk of a crankshaft associated with a firing event in an engine. The misfire confirmation module selectively confirms that a misfire detected in the engine is valid based on the jerk.

Target Wheel Position Detection Systems

US Patent:
8176896, May 15, 2012
Filed:
Jan 22, 2009
Appl. No.:
12/357776
Inventors:
Julian R. Verdejo - Farmington MI, US
Nicholas John Kalweit - Novi MI, US
David S. Mathews - Howell MI, US
Michael R. Grimes - Saline MI, US
International Classification:
F02D 41/34
F02P 5/15
F02P 5/00
US Classification:
12340665, 7311404, 12340658
Abstract:
A control module for a vehicle includes a time recording module that stores timestamps that correspond to each of N teeth of a target wheel of the vehicle in memory. N is an integer. A position module generates M angular positions based on the timestamps. M is an integer greater than one. Each of the M angular positions corresponds to a space between adjacent ones of the N teeth. A position estimator determines position of the target wheel based on the M positions.
