Patent number: 8352225Abstract: A process for simulating and assembling flexible parts includes creating an ideal path between first and second planes and placing a virtual rigid envelope around the ideal path, and possibly tubular extensions beyond the path. A virtual flexible part is marked with reference features and pulled through the virtual rigid envelope, such that the path of the virtual flexible part is constrained but may rotate. Removing the virtual rigid envelope allows the virtual flexible part to relax, causing it to move to its lowest energy state. Zero-twist end conditions on the virtual flexible part are marked, corresponding to the intersection of the reference features with the planes. Identification marks are placed on a real flexible part, corresponding to the reference strips on the virtual flexible part. The real flexible part may then be assembled by aligning zero-twist marks on mating features to the identification marks on the real flexible part.Type: GrantFiled: November 14, 2008Date of Patent: January 8, 2013Assignee: GM Global Technology Operations LLCInventors: Wuhua Yang, Robert Bruce Tilove, Richard A. Knoth

Patent number: 8346424Abstract: A method of monitoring an onboard diagnostic system for a plug-in hybrid electric vehicle includes incrementing the denominator of an N/D ratio for the onboard diagnostic system only when a total time criteria, a vehicle speed criteria and an idle criteria are satisfied after an internal combustion engine of the vehicle has been fueled. The diagnostic system performance is summarized into a single N/D ratio. When an underperforming ratio is identified, the system controls the engine to provide more engine operation and subsequent diagnostic observability. The denominator of the N/D ratio is compared to a verification denominator to identify vehicles that are typically operated in a manner such that an engine-on cycle does not begin, or is not identified, until very near the end of the drive cycle, thereby preventing the denominator and a numerator of the N/D ratio from incrementing, and thereby providing a false passing performance ratio.Type: GrantFiled: November 9, 2010Date of Patent: January 1, 2013Assignee: GM Global Technology Operations LLCInventors: Andrew M. Zettel, John F. Van Gilder, Saul Scott

Patent number: 8346489Abstract: A method for determining output torque capabilities in a transmission having a first, second, and third node, each of which has a speed and acceleration. The method includes controlling the speed of the first node, calculating a real maximum long-term output torque capability (raw max LT) as a function of at least the acceleration and the speed of the first and second nodes, and calculating an inertialess maximum long-term output torque capability (inertialess max LT), which is identical to the raw max LT except that the inertialess max LT ignores torque capability due to acceleration of the first node. The raw max LT and the inertialess max LT are compared to determine an operating capability for the transmission. The first node may be an input node for the transmission. The method may include determining a new effective minimum long-term output torque capability (new effective min LT) by similar considerations.Type: GrantFiled: September 28, 2010Date of Patent: January 1, 2013Assignee: GM Global Technology Operations LLCInventors: Sean W.

Patent number: 8327750Abstract: A hydraulic control system includes an oil control valve to control oil flow within a valvetrain. The control valve varies the flow rate to actuate an engine component from a first position to a second position based upon fluid pressure from the control valve. Varying the flow rate through the control valve includes increasing the flow rate through the control valve to increase the pressure to a first level to actuate the engine component to the first position. After the engine component is actuated, the flow rate through the control valve is maintained at a level sufficient to maintain the engine component in the first position. To actuate the engine component to the second position the flow rate through the control valve is then decreased. The fluid flow rate through the control valve is then maintained at a level sufficient to maintain the engine component in the second position.Type: GrantFiled: July 22, 2009Date of Patent: December 11, 2012Assignee: Eaton CorporationInventors: Robert D. Keller, Gerrit V. Beneker, Robert A. Dayton
