Remote Diagnostic System For Detecting Tampering Of Vehicle Calibrations
view source
US Patent:

7729824, Jun 1, 2010
Filed:

Jul 29, 2005
Appl. No.:

11/194139
Inventors:

Joseph M. Tolkacz - Novi MI, US
Assignee:

GM Global Technology Operations, Inc. - Detroit MI
International Classification:

G06F 17/00
G06F 19/00
US Classification:

701 33
Abstract:

A tampering diagnostic system for a vehicle comprises a control system that stores calibration data. A transmitter selectively wirelessly transmits the calibration data. A service assistance system that is remote from the vehicle receives the calibration data wirelessly from the transmitter. A manufacturer information system receives the calibration data from the service assistance system, compares the calibration data to factory calibration data, and selectively generates a tampering flag based on the calibration data.

Filed:

Aug 1, 2012
Appl. No.:

13/563835
Inventors:

JOSEPH M. TOLKACZ - Novi MI, US
SHAWN H. SWALES - Canton MI, US
Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI
International Classification:

F16H 3/72
F16H 37/08
US Classification:

475 5, 475198, 180 6522, 903902
Abstract:

A transmission disconnect clutch assembly and method are provided. The clutch assembly operates to place the transmission in a low-loss state, by decoupling the base transmission from the differential gearing, thereby maximizing fuel economy and increasing efficiency. The transmission disconnect clutch assembly may be a dog clutch assembly, which may include a dog clutch hub, a clutch apply plate, and a synchronizer. When the dog clutch is disengaged the vehicle may operate in EV mode, propelled by an electric motor and rear e-axle. When the dog clutch is engaged the vehicle may operate in hybrid mode, propelled by torque transmitted to a front axle by an engine and the torque transmitted to the rear e-axle by the electric motor. A method for transitioning a vehicle between EV mode and hybrid mode, as well as a method for transitioning a vehicle between hybrid mode and EV mode are also provided.

US Classification:

701 22, 903930
Abstract:

Methods and apparatus are provided for torque control in an electric all wheel drive (e AWD) vehicle. The apparatus is a system having at least one propulsion system capable of determining a desired torque command and torque capability data for a primary and secondary axle. Also included are one or more active chassis systems capable of providing chassis system data and a processor coupled for processing the desired torque command, the torque capability data and the chassis system data to provide a maximum torque limit and a minimum torque limit for the secondary axle. In this way, at least one propulsion system processes the desired torque signal and the maximum torque limit and the minimum torque limit to provide an electric motor torque command and an engine torque command for the eAWD vehicle. A method for torque control in an eAWD vehicle is also provided.

US Patent:

20140024495, Jan 23, 2014
Filed:

Jun 24, 2013
Appl. No.:

13/925813
Inventors:

JOSEPH M. TOLKACZ - NOVI MI, US
R TRAVIS SCHWENKE - SPRINGBORO OH, US
RANDALL B. DLUGOSS - ROYAL OAK MI, US
International Classification:

B60W 10/06
B60W 10/02
US Classification:

477167
Abstract:

A hybrid transmission includes a transmission having a selectable clutch device effective when engaged to mechanically couple an internal combustion engine to a first axle at a fixed engine speed to axle speed ratio. A method for starting the engine includes executing an engine start event including spinning and fueling the engine such that an engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio, and engaging said selectable clutch device after the engine speed to axle speed ratio exceeds the fixed engine speed to axle speed ratio.

US Patent:

57202583, Feb 24, 1998
Filed:

Dec 16, 1996
Appl. No.:

8/766077
Inventors:

Joseph Mark Tolkacz - Novi MI
William Joseph Bolander - Ortonville MI
Robert Charles Simon - Novi MI
Gary Arthur Nichols - Farmington Hills MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

F02D 4116
US Classification:

123352
Abstract:

Control of engine speed responsive to a deviation in engine speed away from a target speed is applied selectively under closed-loop airflow control operating conditions, such as idle and coastdown operating conditions in response to analysis of a cause of an engine intake airflow deviation away from a modeled airflow. If airflow deviations are determined to have resulted from variation in internal engine friction away from a nominal friction level, the control is applied. If airflow deviations are determined to have resulted from change in internal engine airflow restriction, such as due to contaminant build-up over a period of engine use, then the control is not applied under closed-loop airflow control operating conditions to avoid overcompensating for such deviations.

US Patent:

51860805, Feb 16, 1993
Filed:

Feb 7, 1992
Appl. No.:

7/831144
Inventors:

Robert C. Simon - Novi MI
George C. Mitchell - Ypsilanti MI
Joseph M. Tolkacz - Warren MI
William G. Polom - Mt. Clemens MI
Peter M. Medich - Birmingham MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

B60K 4104
B60K 4106
US Classification:

74857
Abstract:

When the throttle of a vehicle engine is released by the vehicle operator of a vehicle having an automatic transmission, the slip of the automatic transmission is measured and the airflow of the engine is trimmed as a function of the measured slip to establish a desired drive-on feel of the vehicle during coastdown.

Method Of Learning Gain For Throttle Control Motor

US Patent:

50334310, Jul 23, 1991
Filed:

Jul 2, 1990
Appl. No.:

7/546452
Inventors:

David C. Poirier - Troy MI
Joseph M. Tolkacz - Warren MI
George C. Mitchell - Ypsilanti MI
Robert C. Simon - Novi MI
Peter M. Medich - Birmingham MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

F02D 4100
US Classification:

123339
Abstract:

An idle speed control motor under computer control positions a throttle stop for setting minimum throttle angles. The motor response to actuating pulses varies from motor to motor so that a gain factor is determined for each motor and is used to calculate the required pulse width to attain a desired throttle displacement. A gain learn program in the engine control computer runs when the ignition is turned off and is effective to extend the motor with a number of pulses of known width, measure the throttle displacement, and determine the gain factor by dividing a standard displacement by the measured displacement. The same program is applied to learning the gain of a throttle motor in an electronic throttle control system.

Transferable Electronic Control Unit For Adaptively Controlling The Operation Of A Motor Vehicle

US Patent:

53943279, Feb 28, 1995
Filed:

Oct 27, 1992
Appl. No.:

7/967871
Inventors:

Robert C. Simon - Novi MI
Joseph M. Tolkacz - Warren MI
Steven J. Swantick - Livonia MI
Dennis D. Thompson - Atlanta IN
Douglas J. Tackitt - Kokomo IN
Assignee:

General Motors Corp. - Detroit MI
Delco Electronics Corp. - Kokomo IN
International Classification:

G06F 1520
US Classification:

36442401
Abstract:

A transferable electronic control unit having a non-volatile memory that retains values of learned correction factors for control parameters used in adaptively controlling the operation of a vehicle is disclosed. The electronic control unit receives an identification signal from the vehicle in which it operates. By comparing the value of the received identification signal with a stored value identifying the vehicle operated when learning the values of the correction factors that are stored in non-volatile memory, the electronic control unit determines whether or not it has been transferred between vehicles. When a transfer between vehicles has not occurred, the value of the learned correction factors stored in non-volatile memory are used to begin adaptively controlling vehicle operation. When a transfer between vehicles has occurred, initial or mean values for the correction factors are used to begin adaptively controlling vehicle operation. As a result, the electronic control unit can be transferred between vehicles without causing malfunctions in vehicle operation.
