Pulse Generator For Indicating A Change In The Magnitude Of An Input Signal
view source
US Patent:

6384640, May 7, 2002
Filed:

Oct 26, 2000
Appl. No.:

09/697575
Inventors:

Paul Louis Du Bois - Flint MI
William Frank Pakkala - Owosso MI
Joyce Dale Carsey - Swartz Creek MI
Daniel Alexander Crawford - Burton MI
Steven C. Kekel - Grand Blanc MI
Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

H03K 5153
US Classification:

327 90, 327 72
Abstract:

A pulse generator for indicating a change in the magnitude of an input signal includes a comparator, a first network connected to one input of the comparator for receiving the input signal, and a second network connected to the other input of the comparator for receiving the input signal. Both the first and second networks provide output signals to the comparator which transition in response to a magnitude change of the input signal from their respective baseline magnitudes to respective peak magnitudes, and back to their respective baseline magnitudes. The component values of the networks are selected such that one of the first or second network output signals is positive relative to the other network output signal over some period of time during the transition to the peak magnitude and return to the baseline magnitude to cause the comparator to generate a pulse indicating a change in the magnitude of the input signal.

US Patent:

6588400, Jul 8, 2003
Filed:

May 14, 2001
Appl. No.:

09/855198
Inventors:

Thomas E. Gyoergy - Clarkston MI
Joyce Dale Carsey - Swartz Creek MI
Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

F02D 100
US Classification:

123399, 123361, 731181
Abstract:

A multi-strike throttle minimum learning system compares a signal received from at least one throttle position sensor to a predetermined minimum throttle position range based on throttle system component tolerances. A possible throttle obstruction is indicated when all of the sensor signal minimum values are outside the predetermined minimum range. In this case, the system deactivates electrical power for a predetermined delay period and then initiates another learn attempt in an effort to overcome the obstruction. This cycle is repeated until a valid throttle minimum position is detected, the number of learn attempts reaches a preset maximum, or a sensor fault is detected. If a valid throttle position minimum is detected within the allowed number of learning attempts, normal engine startup proceeds; otherwise, appropriate fault codes are communicated to the balance of the engine management system and, ultimately, to the operator.

Abstract:

An embodiment of the invention is an actuator controller for use in an actuator assembly. The actuator controller includes a processor for controlling an actuator associated with the actuator controller. A communication device is in communication with the processor. The communication device receives control commands from a master controller and is capable of communicating in multiple languages. A memory is accessible by the processor and the processor determines the language of the control commands and retrieves a control program from the memory corresponding to the language.

US Patent:

7855525, Dec 21, 2010
Filed:

Oct 30, 2007
Appl. No.:

11/928718
Inventors:

Stephen P. Sanders - Millington MI, US
Joyce D. Carsey - Swartz Creek MI, US
Lawrence D. Hazelton - Goodrich MI, US
Jos Lang - Bertrange, LU
Frederic Jacquot - Thionville, FR
Thomas W. Newman - Flint MI, US
Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

G05D 3/00
US Classification:

318466, 318280, 318283
Abstract:

An actuator includes a motor operated by a controller through a pulse width modulation drive signal applied to a drive circuit that drives the motor. The actuator has an output shaft connected to a coupling structure for manipulating a device such as a variable geometry turbine (VGT) or an exhaust gas recirculation (EGR) valve. The device has a range of motion limited by first and second mechanical stops located at opposing low and high ends of the range. The controller learns the location of the mechanical stops during calibration. An external control unit transmits a desired position to the actuator. A protocol allows the external control unit to implicitly request a positioning mode by virtue of what value range the desired position falls into. The controller is configured to limit the drive signal to a non-harmful level when one of the positioning modes calls for pushing the device against one of the stops.

Appl. No.:

09/906315
Inventors:

Daniel Crawford - Burton MI, US
Joyce Carsey - Swartz Creek MI, US
International Classification:

G06F019/00
US Classification:

702/122000
Abstract:

An exemplary embodiment of the invention is an actuator assembly having a controller integrated into the actuator assembly. The controller includes a memory for storing test cycle data and a processor in communication with the memory. The processor accesses the test cycle data. A communication port is in communication with the processor and in communication with an actuator and a sensor. During a test mode, the processor provides position commands to the actuator and receives a sensor signal from the sensor. The processor detects the presence of faults in response to the sensor signal and stores the faults in the memory.

Abstract:

A method for indirectly sensing absolute position of a mechanical output device of an electromechanical (EM) system is disclosed. In an exemplary embodiment, the method includes detecting the location of a reference point established within a defined range of travel of the mechanical output device, and tracking a relative position of the mechanical output device through the movement of an electromotive actuator within the EM system. The absolute position of the mechanical output device is determined by comparison of the tracked relative position of the mechanical output device to the established reference point.

Motor Vehicle Cruise Control With Selectively Updated Integral Gain

US Patent:

62789317, Aug 21, 2001
Filed:

Apr 4, 2000
Appl. No.:

9/542375
Inventors:

Daniel Alexander Crawford - Burton MI
David Lynn Ehle - Lapeer MI
Joyce Dale Carsey - Swartz Creek MI
Diana K. Voges - Fenton MI
Michael G. Schuplin - Davison MI
Robert Harold Wind - Grand Blanc MI
Assignee:

Delphi Technologies, Inc. - Troy MI
International Classification:

B60K 3104
US Classification:

701 93
Abstract:

An improved cruise control which produces a desired throttle position that is based in part on a selectively updated integral term. The integral term is only updated when the magnitude of the speed error exceeds a predefined value, thereby eliminating changes in the integral term when the speed error is smaller than the predefined threshold. In other words, the integral term is dynamic and responsive to a current error condition when the speed error magnitude exceeds the threshold, and static when the speed error is within the threshold. In this way, the operational advantages of the integral term are retained while avoiding its disadvantages, and the transition between the static and dynamic states of the integral term are smooth and seamless.
