Filed:

Feb 20, 2004

Appl. No.:

10/689184

Inventors:

David A. Stamm - Howell MI, US
Todd R. Shupe - Milford MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

G06G 7/70

US Classification:

701114, 123494, 123361, 123399, 701102, 701103, 701104, 731182

Abstract:

A throttle area compensation system for use with an electronic throttle control of a vehicle includes a compensation datastore of compensation values indexed by pre-compensated throttle area. A compensation vector learning module receives a pre-compensated throttle area and at least one sensed vehicle condition, and informs the compensation datastore based on the pre-compensated throttle area and the sensed vehicle condition. A throttle area compensation module communicates with the compensation datastore, receives the pre-compensated throttle area, and determines a compensated throttle area based on the pre-compensated throttle area and a corresponding compensation value of the compensation data store.

Appl. No.:

11/516013

Inventors:

Paul A. Bauerle - Fenton MI, US
David A. Stamm - Howell MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F02D 41/26
F02D 9/00

US Classification:

701115, 123399, 701102

Abstract:

A correction system and method for an electronic throttle control includes a generator module that generates a learned-correction value corresponding to a first air-learn index. The learned-correction value is used to compensate a throttle position. A correction module writes to a throttle position correction array with the learned-correction value when an air-learn value equals a predetermined stability threshold.

Appl. No.:

11/711915

International Classification:

B60W 10/02
B60W 10/06
B60W 10/10

US Classification:

477108

Abstract:

A control system for regulating operation of a vehicle having a transmission driven by an engine during a cruise control mode includes a first module that determines an operating point of the vehicle and that compares the operating point to one of a shift line and a torque converter clutch (TCC) release line. A second module regulates a throttle of the engine to maintain the operating point a threshold distance from the one of the shift line and the TCC release line, when the operating point is at the threshold distance.

International Classification:

G06F 19/00
B60T 8/32

US Classification:

701110, 701 93, 123319, 123399

Abstract:

An engine control system that regulates operating of an engine of a motor vehicle includes a first module that determines whether a throttle of the motor vehicle is closed and a second module that determines whether the engine is idling while a cruise control is active. A third module selectively inhibits an RPM-based idle speed control of the engine if the throttle is closed and the engine is idling while the cruise control is active.
