Publication number: 20150149088Abstract: A vehicle is operated at least partially autonomously. A predicted path of the vehicle is monitored to identify an object with which the vehicle is likely to collide. A graphical user interface (GUI) is provided that includes the predicted path, a proposed path for the vehicle to avoid a collision with an object, and the vehicle. A selection is made to follow one of the predicted path and the proposed path. The GUI is updated to include the selected one of the predicted path and the proposed path, along with a location of the vehicle on the selected one of the predicted path and the proposed path.Type: ApplicationFiled: November 22, 2013Publication date: May 28, 2015Applicant: Ford Global Technologies, LLCInventors: Christopher Attard, Shane Elwart, Jeff Allen Greenberg, Rajit Johri, John P.

Publication number: 20140287872Abstract: A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.Type: ApplicationFiled: June 4, 2014Publication date: September 25, 2014Applicant: Ford Global Technologies, LLCInventors: Christopher John Teslak, Gregory Michael Pietron, Hongtei Eric Tseng, Yuji Fujii, Michael Glenn Fodor, Diana Yanakiev, Seung-Hoon Lee

Patent number: 8738254Abstract: A non-synchronous automatic transmission up-shift control utilizes input torque measurements. The input torque is measured during an up-shift having preparatory, torque, and inertia phases. Target input torque profiles for the torque and inertia phases are determined based on the input torque during the preparatory phase. During the torque phase, an engine torque is controlled to cause the input torque to achieve the target profile for the torque phase. During the inertia phase, the on-coming clutch is controlled to cause the input torque to achieve the target profile for the inertia phase.Type: GrantFiled: November 19, 2010Date of Patent: May 27, 2014Assignee: Ford Global Technologies, LLCInventors: Seung Hoon Lee, Yuji Fujii, Bradley Dean Riedle, Gregory Michael Pietron, Diana Yanakiev, Joseph F.

Publication number: 20140121059Abstract: A multiple ratio transmission having an input shaft, an output shaft and oncoming clutch and off-going clutch for effecting ratio upshifts is provided. The transmission also includes a transmission controller configured for controlling shifts. During the torque phase of a ratio upshift, the controller increases input torque. Next, the controller estimates an oncoming clutch target torque. The controller controls a torque input to ensure the off-going clutch remains locked. The controller measures an actual transmission value for a torque transmitting element of the transmission and corrects the oncoming clutch target torque using the actual transmission value whereby an increasing torque for the oncoming friction element is achieved with minimal torque transients along the output shaft during the upshift.Type: ApplicationFiled: January 3, 2014Publication date: May 1, 2014Applicant: Ford Global Technologies, LLCInventors: Christopher John Teslak, Gregory Michael Pietron, Hongtei Eric Tseng, Yuji Fujii, Michael Glenn Fodor, Diana Yanakiev, Seung-Hoon Lee

Patent number: 8694223Abstract: A method of controlling a traction control system (30) includes continuously adapting a steady state driven wheel speed to reference wheel speed ratio, so that said traction control system can avoid unnecessary actuations (e.g., demanding torque reduction). The continuous adaptation methodology provides traction control robustness to vehicles equipped with a spare tire, or a different final drive such as in the use of aftermarket parts. The method includes a dual rate adaptation that allows both fast adaptation and fine tuning capabilities of the ratio. The method includes comparing the instant driven wheel speed to reference wheel speed ratio to the filtered driven wheel speed to reference wheel speed ratio, to obtain a ratio difference. When the difference is above a threshold, the first filter constant is selected and the first constant is applied to an adaptation filter, resulting in a first filtered and adapted ratio. The traction control system is controlled with the adapted ratio.Type: GrantFiled: February 19, 2009Date of Patent: April 8, 2014Assignee: Ford Global Technologies, LLCInventors: Hongtei Eric Tseng, Michael Fodor, Davor Hrovat
