Patent number: 10118499Abstract: A vehicle includes a traction battery and a controller programmed to, in response to a first ignition cycle after a charging of the traction battery, output a distance until charge prediction based on one or more selected distance estimates from filtered sets of historical data that are derived by filtering historical data based on a time and a day of the first ignition cycle. The selected distance estimates may be from filtered sets having more than a predetermined number of members. The selected distance estimates may be from filtered sets having a variance that is less than an overall historic variance. The filtered sets may include members of an unfiltered set based on a time of day and day of week.Type: GrantFiled: September 23, 2014Date of Patent: November 6, 2018Assignee: Ford Global Technologies, LLCInventors: Payam Naghshtabrizi, Johannes Geir Kristinsson

Publication number: 20170227103Abstract: A torque vectoring differential constructed in accordance to the present disclosure includes a differential carrier rotatable about an axis. A pinion carrier can have at least one pinion gear mounted for rotation on at least a portion of the pinion carrier. First and second side gears can be meshed for engagement with at least one pinion gear. The first side gear can be engaged for rotation with a first axle shaft. The second side gear can be engaged for rotation with a second axle shaft. A first clutch can be operable to selectively lock the differential carrier and the pinion carrier with respect to one another for rotation about the axis. A second clutch can be operable to selectively lock the differential carrier to the first side gear. A third clutch can be operable to selectively lock the differential carrier to the second side gear.Type: ApplicationFiled: April 26, 2017Publication date: August 10, 2017Applicant: Eaton CorporationInventors: Douglas Hughes, Payam Naghshtabrizi, James K.

Publication number: 20170130815Abstract: A torque vectoring system constructed in accordance to one example of the present disclosure includes a differential, a first drive axle, a second drive axle, a first gear train and a second gear train. The first drive axle is operably coupled to the differential. The second drive axle is operable coupled to the differential. The first gear train is selectively driven by the differential and is configured to selectively supply a speed application from the differential to one of the first and second drive axles. The second gear train is selectively driven by the differential and is configured to selectively supply a speed reduction from the differential to one of the first and second drive axles.Type: ApplicationFiled: January 25, 2017Publication date: May 11, 2017Inventors: Hongbin Wang, Sean Brown, Payam Naghshtabrizi, Richard Kukucka, Gregory Heatwole, Andrew Edler

Patent number: 9328680Abstract: Methods and systems are provided for accurately determining cylinder fueling errors during an automatic engine restart. Fueling errors may be learned during a preceding engine restart on a cylinder-specific and combustion event-specific basis. The learned fueling errors may then be applied during a subsequent engine restart on the same cylinder-specific and combustion event-specific basis to better anticipate and compensate for engine cranking air-to-fuel ratio deviations.Type: GrantFiled: November 15, 2013Date of Patent: May 3, 2016Assignee: Ford Global Technologies, LLCInventors: Sam Hashemi, Payam Naghshtabrizi

Patent number: 9056550Abstract: A system includes a GPS receiver that generates a signal that is representative of a posted speed limit at a location where a vehicle is located and a device that generates a signal that is representative of an actual speed of the vehicle. A controller is responsive to the GPS receiver signal and the actual speed sensor signal for either (1) generating an alarm or (2) limiting or otherwise controlling the speed of the vehicle when the actual speed of the vehicle is greater than the posted speed limit.Type: GrantFiled: October 26, 2011Date of Patent: June 16, 2015Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Viet Quoc To, Payam Naghshtabrizi, Sam Hashemi, Zhang Yan, John R.

Patent number: 9020743Abstract: A computer implemented trip-planning method includes accessing one or more destination elements of a matrix of driver information, the accessing based at least in part on a trip start time and day of week. Each accessed element has a probability associated therewith, indicating the likelihood of the element being the destination at which a vehicle trip will end, based at least the start time and day of week. The method also includes selecting, from the one or more elements, a destination having the highest probability of being the destination at which the vehicle trip will end. Further, the method includes utilizing the selected destination as an end destination for the purposes of trip planning.Type: GrantFiled: February 20, 2012Date of Patent: April 28, 2015Assignee: Ford Global Technologies, LLCInventors: Dimitar Petrov Filev, Ryan Abraham McGee, Johannes Geir Kristinsson, Payam Naghshtabrizi, Fling Tseng

Publication number: 20140016797Abstract: A method and system for changing a digital signal processing (DSP) mode of an audio system in a motor vehicle having a roof movable between open and closed positions. The open/closed position of the roof is determined and the audio system is operated in a first DSP mode when the roof is in the closed position and operated in a second DSP mode when the roof in the open position. The first and second DSP modes have different processing characteristics adapted for the acoustics of the passenger cabin when the roof is closed or open. The open/closed roof position may be determined by a roof position sensor or by the actuation of a roof position switch operated by a vehicle occupant.Type: ApplicationFiled: July 16, 2012Publication date: January 16, 2014Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Chait Phagoo, John Richard Blankenship, Zhang Yan, Payam Naghshtabrizi, Viet Quoc To
