Method Of Adaptively Idling An Electronic Automatic Transmission System

US Patent:
49657283, Oct 23, 1990
Filed:
Apr 29, 1988
Appl. No.:

Inventors:
Maurice B. Leising - Clawson MI
Howard L. Benford - Bloomfield Hills MI
Michael R. Lindsay - Livonia MI
Jay C. McCombie - Rochester Hills MI
Assignee:
Chrysler Corporation - Highland Park MI
International Classification:
B60K 4102
F16H 558
US Classification:
3644241
Abstract:
A method of adaptively idling a transmission in an electronic automatic transmission system putting the transmission to "neutral" when the engine is idling and the brakes are applied.

Single Sensor Misfire Detection Apparatus And Method For An Internal Combustion Engine

US Patent:
53616294, Nov 8, 1994
Filed:
Aug 21, 1992
Appl. No.:
7/934057
Inventors:
Jay C. McCombie - Rochester Hills MI
Assignee:
Chrysler Corporation - Highland Park MI
International Classification:
G01M 1500
F02M 5100
F02P 5145
US Classification:
731173
Abstract:
A misfire detection apparatus and method is provided for detecting misfire in cylinders of an internal combustion engine in a motor vehicle. The method includes sensing rotation of a crankshaft and calculating a crankshaft velocity based on the sensed rotation of the crankshaft. The method also includes compensating the calculated crankshaft velocity based on a predetermined cylinder. The method further includes comparing either the calculated or compensated crankshaft velocity to a predetermined crankshaft velocity range to determine if therein, and counting a misfire if either the calculated or compensated crankshaft velocity is within the predetermined crankshaft range.

Method Of Determining And Using An Acceleration Correction In An Integrated Acceleration Based Electronic Speed Control System For Vehicles

US Patent:
48498920, Jul 18, 1989
Filed:
Mar 6, 1987
Appl. No.:
7/023055
Inventors:
Jay C. McCombie - West Bloomfield MI
Assignee:
Chrysler Motors Corporation - Highland Park MI
International Classification:
G05D 1358
B60K 3100
US Classification:
36442604
Abstract:
A method of determining and using an acceleration correction in a acceleration based electronic speed control system for automobiles, the method being utilized by a microcontroller. An error correction pulse is selected by integrating (or summing) the differences between the desired acceleration and the actual vehicle acceleration. The integral is compared to a trigger window. The throttle position is controlled based on the value of the integral as compared to the window. This is keyed in providing smooth control. The integration action serves to filter transient acceleration errors to dampen throttle response to prevent throttle correction at a faster rate than the vehicle can respond thereby reducing over and under shoot of the throttle.

Fuel Injection System And Control Valve For Multi-Cylinder Engines

US Patent:
41800222, Dec 25, 1979
Filed:
Oct 31, 1977
Appl. No.:
5/846755
Inventors:
Magdi K. Khair - Birmingham MI
Jay C. McCombie - West Bloomfield MI
Assignee:
Chrysler Corporation - Highland Park MI
International Classification:
F02B 300
F02M 3900
US Classification:
123 32AE
Abstract:
A fuel injection system and control valve are disclosed for use with a multi-cylinder engine such as a diesel or proco type engine. The disclosed control valve, which is of the piezoelectric type, controls the fuel injection into the individual cylinders by being connected in fluid circuit between the high pressure pump and distributor which are contained in the pump and distributor assembly. The control valve contains novel features providing improvements in the system.

Method Of Determining And Using A Filtered Speed Error In An Integrated Acceleration Based Electronic Speed Control System For Vehicles

US Patent:
48602108, Aug 22, 1989
Filed:
Mar 6, 1987
Appl. No.:
7/023165
Inventors:
Jay C. McCombie - West Bloomfield MI
Assignee:
Chrysler Motors Corporation - Highland Park MI
International Classification:
G06G 770
B60K 3100
US Classification:
36442604
Abstract:
Speed error is calculated by finding the difference between set speed and vehicle speed and then filtering the result. The error is tested for polarity and magnitude before selecting a desired acceleration rate. This acceleration rate is used in an acceleration based electronic speed control system for vehicles.

Dual Sensor Misfire Detection Apparatus And Method For An Internal Combustion Engine

US Patent:
55616003, Oct 1, 1996
Filed:
Aug 3, 1995
Appl. No.:
8/510884
Inventors:
Jay C. McCombie - Rochester Hills MI
Assignee:
Chrysler Corporation - Auburn MI
International Classification:
G01M 1500
US Classification:
36443108
Abstract:
A misfire detection apparatus and method is provided for detecting misfire in cylinders of an internal combustion engine in a motor vehicle. The method includes sensing rotation of a crankshaft and calculating a crankshaft velocity based on the sensed rotation of the crankshaft. The method also includes repeating the sensing and calculating steps a predetermined number of times to develop a measured crankshaft velocity profile. The method further includes obtaining a stored misfire velocity profile based on speed of the crankshaft, comparing the measured crankshaft velocity profile to the stored misfire crankshaft velocity profile to determine if a match exists, and counting a misfire if a match exits.

Engine Misfire Detection With Compensation For Normal Acceleration Of Crankshaft

US Patent:
55742173, Nov 12, 1996
Filed:
Jun 6, 1995
Appl. No.:
8/468117
Inventors:
Jay C. McCombie - Rochester Hills MI
Assignee:
Chrysler Corporation - Auburn Hills MI
International Classification:
G01M 1500
US Classification:
73116
Abstract:
An apparatus and method are provided for detecting cylinder misfires in an internal combustion engine of a motor vehicle which is capable of detecting multiple cylinder misfires and more particularly opposed cylinder misfires. Crankshaft rotation is sensed and crankshaft velocities are measured for each cylinder. Changes in angular velocity are determined and correspond to each of a plurality of cylinder firing events. Angular velocity changes are sorted over a predetermined series of cylinder firings and the two middle most angular velocity changes are averaged to provide an average change in velocity value. A deviation is determined between the change in angular velocity for a selected cylinder and the average change in velocity value. The deviation is compared to a threshold value and a misfire event is determined for the selected cylinder based on the comparison.
