US Patent:

8364364, Jan 29, 2013
Filed:

Sep 12, 2011
Appl. No.:

13/230256
Inventors:

Xuefeng Tim Tao - Northville MI, US
John William Boughner - Howell MI, US
Jonathan P. Kish - Royal Oak MI, US
Jayson S. Schwalm - Farmington Hills MI, US
International Classification:

G06F 19/00
US Classification:

701 68, 701 51, 74329, 74330, 74331, 74335, 74340, 13711802, 137597, 13762569, 244169, 2441713, 2441715, 180 656, 180 6522, 477 3, 477 5
Abstract:

A control system for a vehicle having a dry dual clutch transmission (DCT) includes a launch condition detection module, a vehicle stop module, and a vehicle launch module. The launch condition detection module detects a launch condition based on whether (i) the vehicle is on an uphill grade and (ii) a driver of the vehicle has requested power via an accelerator. The vehicle stop module stops the vehicle when the launch condition is detected by (i) commanding an on-coming clutch of the dry DCT to a predetermined position and (ii) applying brakes of the vehicle. The vehicle launch module launches the vehicle after the vehicle is stopped by (i) fully engaging the on-coming clutch of the dry DCT and (ii) opening a throttle to a desired position corresponding to the power request.

US Patent:

8626424, Jan 7, 2014
Filed:

Aug 5, 2009
Appl. No.:

12/536010
Inventors:

Jayson S. Schwalm - Farmington Hills MI, US
Steven Thomas Ford - Brighton MI, US
John J. Koenig - Howell MI, US
International Classification:

G06F 19/00
B60K 31/00
US Classification:

701110, 701 94, 180170
Abstract:

An engine control system of the present disclosure comprises a target speed module and a coupling module. The target speed module determines a target speed of a vehicle based on a speed of the vehicle and at least one of an accelerator input and a speed control input. The coupling module controls coupling of an engine system and a drive system of the vehicle based on the speed and the target speed. The engine system transfers torque to the drive system when coupled and does not transfer torque to the drive system when decoupled. In other features, the engine control system further comprises a torque control module that controls torque output by the engine system based on the coupling of the engine system and the drive system, the speed, and the target speed.

US Patent:

20090118988, May 7, 2009
Filed:

Feb 28, 2008
Appl. No.:

12/039130
Inventors:

Douglas J. Moening - Farmington MI, US
Igor Anilovich - Walled Lake MI, US
John W. Siekkinen - Novi MI, US
Jayson S. Schwalm - Farmington Hills MI, US
Daniel J. Wickman - Plymouth MI, US
Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - Detroit MI
International Classification:

F02D 45/00
US Classification:

701109, 123325
Abstract:

A system comprises a post oxygen performance diagnostic (POPD) module that performs a POPD of a post oxygen sensor, wherein the POPD includes a deceleration fuel cutoff (DFCO) portion. A torque converter control module adjusts operation of a torque converter clutch (TCC). The POPD module and the torque converter control module operate the TCC to control engine speed above a predetermined engine speed during the DFCO portion of the POPD. A method comprises performing a POPD of a post oxygen sensor, wherein the POPD includes a deceleration fuel cutoff (DFCO) portion and adjusting operation of a torque converter clutch (TCC) to control engine speed above a predetermined engine speed during the DFCO portion of the POPD.

US Patent:

20150369364, Dec 24, 2015
Filed:

Jun 24, 2014
Appl. No.:

14/313063
Inventors:

- Detroit MI, US
Xuefeng Tim Tao - Northville MI, US
Jayson S. Schwalm - Farmington Hills MI, US
Craig J. Hawkins - Howell MI, US
Jeryl McIver - Inkster MI, US
International Classification:

F16H 61/688
F16D 48/06
Abstract:

A method for learning the bite point of a position-controlled clutch in a vehicle having an engine and a transmission includes commanding an engagement of a clutch fork via a controller when the transmission is in park and the engine is idling. The method also includes controlling an apply position of the clutch via the controller, calculating a clutch torque capacity of the clutch, and measuring the apply position via a position sensor. The apply position is recorded as the clutch bite point when the calculated clutch torque capacity equals a calibrated clutch torque capacity. The transmission is then controlled using the recorded clutch bite point. A system includes the transmission, input clutches, and a controller configured to execute the method. A vehicle includes an engine, the transmission, the position-controlled input clutch, and the controller, as well as a clutch position sensor.

US Patent:

20150051803, Feb 19, 2015
Filed:

Aug 16, 2013
Appl. No.:

13/968748
Inventors:

- Detroit MI, US
Daniel Deras - Brighton MI, US
Jayson S. Schwalm - Farmington Hills MI, US
Jeryl McIver - Inkster MI, US
Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI
International Classification:

F16D 48/06
US Classification:

701 68
Abstract:

A method of learning a kiss point of a first clutch of a dual clutch transmission includes controlling a rotational speed of the input shaft to be within a pre-determined range. When both the first clutch and the second clutch are determined to be disengaged from the input shaft, and the rotational speed of the input shaft is within the pre-determined range, then the first clutch is moved from a disengaged position into an engaged position. An increase in a rotational speed of a first transmission shaft, which is coupled to the first clutch, is detected. When the increase in the rotational speed of the first transmission shaft is detected, a position of the first clutch is identified. The identified position of the first clutch is saved in a memory of a transmission control module as a learned first clutch kiss point.
