Patent number: 9879589Abstract: A method of initializing operation of a shutter arranged relative to a grille opening in a vehicle having a power-plant includes detecting a start-up of the power-plant. The method also includes sensing a temperature of ambient air. The method also includes commanding the shutter to achieve a fully-opened position when the temperature of ambient air is above a predetermined value such that a flow of ambient air to the power-plant through the grille opening is substantially unrestricted. The method additionally includes commanding the shutter to achieve a fully-closed position when a temperature of the power-plant is maintained below a threshold value such that the flow of ambient air through the grille opening to the power-plant is substantially blocked. A vehicle using a controller configured to perform the above method is also provided.Type: GrantFiled: August 6, 2012Date of Patent: January 30, 2018Assignee: GM Global Technology Operations LLCInventors: Scott P. Charnesky, David J. Verbrugge, David A. Schoener, William J. Raymor, John C. Remy, Brian A. MacFarlane

Patent number: 8479853Abstract: A system for controlling a flow rate of an airstream through a compartment includes a panel configured to cover the compartment. The system also includes a first opening defined by the compartment and configured to permit the airstream to enter the covered compartment from the ambient when the compartment is covered by the panel. The system also includes a second opening defined by the panel and configured to permit at least a portion of the airstream to exit the covered compartment to the ambient. The system additionally includes a selectable position shutter assembly configured to control the size of the second opening and adjust a flow rate of the airstream through the covered compartment. A vehicle employing the shutter assembly to vary a flow rate of at least a portion of an airstream through the vehicle's under-hood area is also disclosed.Type: GrantFiled: May 17, 2011Date of Patent: July 9, 2013Assignee: GM Global Technology Operations LLCInventor: David J.

Publication number: 20130103265Abstract: A method of acknowledging a presence of an individual relative to a vehicle having a grille opening includes detecting that the vehicle is stationary. The method also includes sensing the presence of the individual relative to the vehicle. The method additionally includes setting an adjustable shutter in motion in response to the sensed presence of the individual when the vehicle is stationary. The shutter is arranged relative to the grille opening and is operable to selectively open and close the grille opening to present an appearance of a “wink”. A system using a controller configured to regulate the shutter and perform such a method is also provided.Type: ApplicationFiled: October 25, 2011Publication date: April 25, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: John C.

Publication number: 20130081888Abstract: A method of establishing a baseline airflow opening into an under-hood compartment of a vehicle configured to house a powertrain includes providing a fascia for the under-hood compartment. The fascia includes a first grille opening and a second grille opening configured to admit first and second portions of ambient airflow, respectively, into the under-hood compartment. A selectable position shutter assembly is disposed in the second grille opening and configured to control a size of the second grille opening. The baseline airflow opening into the under-hood compartment is the sum of the size of the first grille opening and the minimum size of the second grille opening. The method also includes ascertaining a configuration of the powertrain and setting the minimum size of the second grille opening in response to the ascertained configuration of the powertrain to establish the baseline airflow opening. A system employing the method is also disclosed.Type: ApplicationFiled: September 30, 2011Publication date: April 4, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Scott P.

Patent number: 7899607Abstract: An open-loop control system that provides control signals to active engine mounts to reduce or eliminate the transfer of engine vibration to a vehicle body structure, where the system uses only a crank signal from the engine as an input. The control system includes an instant crank speed variation sensing processor that receives the crank signal from the engine, where the crank signal is a pulsed signal including missing pulses as a result of teeth missing on the vehicle crank wheel. The crank speed variation sensing processor provides a measurement of the instant crank speed variation of the crank signal and minimizes an error in the measurement as a result of the missing pulses. The crank speed variation sensing processor outputs a crank speed sensing variation signal as a sine wave that identifies order content in the crank pulse signal.Type: GrantFiled: November 28, 2007Date of Patent: March 1, 2011Assignee: GM Global Technology Operations LLCInventors: Kwang-Keun Shin, David J.
