Patent number: 8565990Abstract: A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine upon an engine start request, thereby eliminating the need to transfer torque from the motor/generator to the engine. This helps to further reduce torque disturbances in the driveline when the engine is started.Type: GrantFiled: November 13, 2009Date of Patent: October 22, 2013Assignee: Ford Global Technologies, LLC.Inventors: Walter Joseph Ortmann, Daniel Scott Colvin, Brandon R. Masterson, Reid Alan Baldwin, Andrew John Silveri, Francis T. Connolly, Marvin Paul Kraska

Patent number: 8192324Abstract: A vehicle includes a motor/generator, a starter motor, a disconnect clutch disposed between the engine and the motor/generator, and at least one clutch disposed between the motor/generator and the vehicle drive wheels. When an engine start is requested, various parameters are controlled to ensure a smooth engine start wherein driveline torque disturbances are minimized. The starter motor is used to crank the engine at the lowest engine speeds when the engine-required torque is the highest. This reduces the amount of torque necessary to be supplied from the motor/generator, and further helps to reduce torque disturbances in the driveline. If the motor/generator is producing torque to propel the vehicle at the time the engine start is requested, a launch clutch or one or more transmission clutches can be controlled to provide slip between the motor/generator and the vehicle drive wheels to further reduce torque disturbances in the driveline.Type: GrantFiled: November 13, 2009Date of Patent: June 5, 2012Assignee: Ford Global Technologies, LLCInventors: Marvin Paul Kraska, Walter Joseph Ortmann, Brandon R. Masterson, Daniel Scott Colvin, Francis T. Connolly, Andrew John Silveri

Patent number: 7998024Abstract: An automotive transmission transitions from a drive gear to a neutral gear when an engine is shutdown. During a rolling pull-up, a crankshaft of the engine will be spun up to a desired speed and the transmission will transition from the neutral gear to an appropriate gear based on a shift schedule. A target transmission input speed is commanded to be a synchronous speed plus an offset to smoothly transition out of electric axle drive propulsion.Type: GrantFiled: October 15, 2010Date of Patent: August 16, 2011Assignee: Ford Global Technologies, LLCInventors: Andrew John Silveri, Daniel Scott Colvin, Marvin Paul Kraska

Publication number: 20090150035Abstract: A hybrid propulsion system for a vehicle. The hybrid propulsion system including a multiple step fixed-gear transmission device for transmitting torque to a first at least one drive wheel, a first electric energy conversion device coupled to an input of the multiple step fixed-gear transmission device, and a control system, during a deceleration condition, the control system increasing negative torque output of the first electric energy conversion device to meet a desired wheel braking torque in response to the multiple step fixed-ratio transmission transitioning from a first gear ratio to a second gear that is higher than the first gear ratio.Type: ApplicationFiled: December 5, 2007Publication date: June 11, 2009Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ihab S.

Patent number: 6805647Abstract: An automatic transmission for a hybrid electric vehicle where an engine is shut down during vehicle stops to improve fuel economy. The automatic transmission includes a main pump that is driven off of a transmission input shaft, and an electronically driven auxiliary pump. A shut down shuttle valve switches a hydraulic circuit connection from the main pump to the auxiliary pump for a low-reverse clutch and a forward clutch when the vehicle stops in drive or low gear. A pressure transducer, controller and steady state relay allow for closed loop feedback to control the auxiliary pump in order to assure sufficient hydraulic pressure while minimizing power consumption.Type: GrantFiled: September 27, 2002Date of Patent: October 19, 2004Assignee: Ford Motor CompanyInventors: Andrew John Silveri, Marvin Paul Kraska, Walter Joseph Ortmann
