US Patent:

7885748, Feb 8, 2011
Filed:

Sep 13, 2006
Appl. No.:

11/531560
Inventors:

Haytham A. Fayyad - Dexter MI, US
Min K. Kim - Troy MI, US
International Classification:

B60W 10/02
B60W 50/06
B60W 30/02
US Classification:

701 58, 701 68, 701 70, 477904
Abstract:

A vehicle control system for regulating operation of a vehicle having a transmission includes a first module that processes an output shaft signal which is based on rotation of an output shaft of the transmission through a third order Kalman filter to determine an acceleration of the output shaft A second module calculates the acceleration of the vehicle based on the acceleration of said output shaft. A third module regulates operation of the vehicle based on the acceleration of the vehicle.

US Patent:

7979186, Jul 12, 2011
Filed:

Mar 4, 2008
Appl. No.:

11/829224
Inventors:

Haytham A. Fayyad - Dexter MI, US
William R. Mayhew - Ann Arbor MI, US
International Classification:

F16H 61/48
B60W 10/02
G01M 13/02
US Classification:

701 67, 701 68, 477176
Abstract:

A torque converter clutch slip rate monitoring system includes a slip rate calculation module that receives a raw slip speed of a torque converter clutch and that calculates torque converter clutch slip acceleration based on the raw slip speed. A torque converter clutch slip rate monitoring module detects deviation of the slip acceleration from a predetermined range during a pulldown of the torque converter clutch.

8328685, Dec 11, 2012
Filed:

Sep 25, 2009
Appl. No.:

12/567208
Inventors:

William R. Mayhew - Ann Arbor MI, US
Haytham A. Fayyad - Dexter MI, US
Stephen R. Tokish - Brighton MI, US
International Classification:

B60W 10/00
US Classification:

477 70, 477 79, 477 86
Abstract:

A method and control module for controlling a transmission of a vehicle includes a clutch torque load predictor module generating a predicted clutch torque load signal for the shift command and a minimum clutch pressure module generating a minimum clutch pressure signal corresponding to a minimum clutch pressure. The control module includes a pressure command module generating a commanded clutch pressure signal for the predicted clutch torque load signal based on the minimum clutch pressure signal and commanding operation of a clutch with a commanded clutch pressure signal. The control module also includes a transmission control module generating the shift command after the clutch torque load predictor module generates the predicted clutch signal, the minimum clutch pressure module generates the minimum clutch pressure signal and the pressure command module generates the commanded clutch pressure signal.

Filed:

Mar 3, 2008
Appl. No.:

12/041286
Inventors:

Haytham A. Fayyad - Dexter MI, US
William R. Mayhew - Ann Arbor MI, US
International Classification:

B60W 10/00
F16H 59/48
G06F 17/00
G06F 19/00
US Classification:

701 51, 701 291, 477 80, 477120
Abstract:

A shift quality error detection system for an automatic transmission includes a vehicle acceleration determination module to determine a vehicle acceleration. An acceptance window module defines upper and lower limits of a desired vehicle acceleration. The shift quality error detection module compares the determined vehicle acceleration to the upper and lower limits of the desired vehicle acceleration. A shift quality error detection module selectively provides a shift quality error based on the comparison. A method of detecting shift quality error of an automatic transmission comprises determining a vehicle acceleration during a transmission gear shift. The method also includes comparing the vehicle acceleration to an acceptance window of desired vehicle accelerations and outputting an error signal based on the acceleration comparison.

US Patent:

20080076630, Mar 27, 2008
Filed:

Sep 11, 2006
Appl. No.:

11/530623
Inventors:

Haytham A. Fayyad - Dexter MI, US
Min K. Kim - Troy MI, US
International Classification:

B60W 10/04
US Classification:

477 35
Abstract:

A differential score protection system that regulates an engine to inhibit damage to a differential driven by the engine includes a first module that initiates a differential score protection mode and a second module that decreases an engine speed when the engine speed exceeds an engine speed limit. The engine speed limit is one of a plurality of pre-determined values based on a design slip speed limit of the differential.
