Publication number: 20110183809Abstract: A transmission shift control system includes a transmission shift control module that executes an upshift or a closed-throttle downshift, a shift stage determination module, and a clutch control module. The stage determination module determines a stage of the upshift or the closed throttle downshift when a downshift is requested. The clutch control module determines a downshift type based on the stage of the upshift or the closed throttle downshift and selectively executes a downshift before the upshift or the closed throttle downshift is completed.Type: ApplicationFiled: January 22, 2010Publication date: July 28, 2011Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Shashikanth Rangaraju, Robert L.

Patent number: 7212898Abstract: The present invention provides a method and apparatus for mathematically calculating an optimal transmission input torque value for the inertia phase and the torque phase of a ratio change. Engine output is then altered by an amount necessary to change the actual value of the transmission input torque to the calculated optimal value of transmission input torque. The timing of the clutch elements during the power-on skip through neutral downshift is established by calculating delay periods for the off-going and on-coming clutches such that a predetermined desired shift time is met. The power-on skip through neutral downshift is thereafter adaptively controlled so that aberrations are diagnosed and corrected during subsequent downshifts. The invention is carried out by monitoring engine and/or transmission characteristics including input speed, output speed and shift duration during a downshift and identifying departures from acceptable patterns.Type: GrantFiled: February 9, 2005Date of Patent: May 1, 2007Assignee: General Motors CorporationInventors: Matthew D. Whitton, Robert L. Williams

Patent number: 5614072Abstract: The invention concerns electrophoresis and methods and electrolyte compositions for decoupling or isolating the dual functions of the electrolyte composition in order to increase separation selectivity or reduce electromigration dispersion, or both. An electrolyte composition is used in electrophoresis to separate a charged analyte having a mobility .mu..sub.a in an electric field. The composition includes a buffer system having an ionic component that controls the pH of the composition and mobility matching ions having a mobility .mu..sub.2 in the electric field, such that .mu..sub.a /.mu..sub.2 equals about one. Alternatively, the buffer system may maintain the composition's pH and a complexing agent may complex with the buffer system to alter the mobility .mu..sub.2 of an ionic component of the buffer system, such that .mu..sub.a /.mu..sub.2 equals about one. The pH of the composition is within a pH range selected based on the analyte to be separated, and .mu..sub.Type: GrantFiled: December 20, 1994Date of Patent: March 25, 1997Assignee: The Texas A&M UniversityInventors: Gyula Vigh, Yasir Y.
