Patent number: 7216025Abstract: An adaptive pressure control method for synchronous downshifts in an automatic transmission that uses pressure actuated friction elements. The method uses characteristic parameters that determine downshift quality for both power-on downshifts and power-off downshifts. Selected measured variables are monitored to detect changes in the parameters. Adjustments for the friction elements are made in response to changes in the measured variables.Type: GrantFiled: November 13, 2003Date of Patent: May 8, 2007Assignee: Ford Global Technologies, LLCInventors: Brian Keyse, Steve Cicala, Ihab Soliman, Charles Suter, Kurt Nickerson, Bradley Riedle

Patent number: 7089102Abstract: An automatic transmission ratio shift control system and method for a powertrain having an engine and multiple-ratio gearing controlled by friction elements actuated by hydraulic pressure, an electronic controller for establishing torque transitions among the friction elements as the gear ratio changes, the engine speed being controlled by an electronic throttle control. The strategy employs an electronic throttle and closed loop engine speed control and uses fuel and air as an energy source to increase engine speed during a power-off downshift. The engine speed is boosted to a level close to the synchronous speed in conjunction with release of the off-going friction element. The on-coming friction element is then applied as the engine speed approaches a desired speed. The engine speed increase is timed to lead an increase in torque converter speed.Type: GrantFiled: September 12, 2003Date of Patent: August 8, 2006Assignee: Ford Global Technologies, LLCInventors: Joseph Slayton, Bradley Riedle, Pramod Jain, Balaram Sankpal, Steven Meisner, David Bidner, Armand Giannamore

Publication number: 20060135316Abstract: A gear ratio shift control and control method controls gear ratio upshifts in a multiple-ratio transmission for an automotive vehicle. Pressure actuated friction elements establish torque flow paths in transmission gearing as they are selectively engaged and released. A net torque reduction at a transmission torque output shaft during an upshift event is reduced by increasing transmission input torque prior to the start of the inertia phase of the upshift event.Type: ApplicationFiled: December 16, 2004Publication date: June 22, 2006Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Yuji Fujii, Marvin Kraska, Gregory Pietron, William Tobler, Walter Ortmann, Bradley Riedle, Ronald Cowan, Davorin Hrovat

Patent number: 7014592Abstract: A method for controlling an automatic transmission in a vehicle is provided. The method selectively provides automatic engine braking for the vehicle. When it is determined that automatic engine braking is desired, the upshift schedule is increased, such that a higher vehicle speed is required to upshift for any given accelerator pedal position. The transmission is automatically downshifted to a lower gear to provide engine braking for the vehicle, when a vehicle acceleration threshold is exceeded. The automatic downshifting of the transmission can occur when the brake pedal is engaged, and when the brake pedal is disengaged.Type: GrantFiled: November 7, 2003Date of Patent: March 21, 2006Assignee: Ford Global Technologies, LLCInventors: Philip Wiethe, Charles Suter, Ken Sovel, Kurt Nickerson, Bruce Palansky, Bradley Riedle

Patent number: 6994647Abstract: An adaptive shift control method for a geared multiple ratio transmission having friction elements for clutches and brakes to establish and disestablish gear ratio changes wherein at least one ratio change involves engagement of one friction element in synchronism with disengagement of another friction element. Operating parameters are adapted throughout the life of the transmission to reduce synchronous errors by developing and learning pressure and time adjustments for the friction elements.Type: GrantFiled: November 13, 2003Date of Patent: February 7, 2006Assignee: Ford Global Technologies, LLCInventors: Steve Cicala, Brian Keyse, Ihab Soliman, Charles Suter, Kurt Nickerson, Bradley Riedle -
