Publication number: 20230264595Abstract: A fuel cell and battery power management system for a fuel cell-powered vehicle includes an electric traction motor, a traction battery in electrical communication with the electric traction motor, a fuel cell stack in electrical communication with the traction battery and the electric traction motor, and a vehicle control system. The vehicle control system is configured to operate the vehicle with at a first discharge power level and a first charging power level if fuel cell power is sufficient alone to navigate the uphill grade and to build up battery state of charge by charging the traction battery at a second charging power level when the vehicle is approaching an uphill grade if fuel cell power is not sufficient alone to navigate the uphill grade. The vehicle control system is further configured to initiate proactive depletion of the battery SOC to enable powertrain braking and to provide regenerative power.Type: ApplicationFiled: February 21, 2022Publication date: August 24, 2023Inventors: Naginder GOGNA, Jason MEYER, Walter Joseph ORTMANN, Stanley L.

Publication number: 20230268525Abstract: The disclosure relates to a vehicle with a traction battery and a fuel cell system, and a controller programmed to purge the fuel cell system by flowing air through it to remove moisture from the fuel cell system. The controller is configured to initiate the purge based on a distance of the vehicle from a destination, a state of charge of the traction battery, and ambient temperature conditions at the destination. The freeze preparation process can be initiated when the vehicle is approaching its destination and can be predicted using connectivity and communication with off-board sources.Type: ApplicationFiled: February 21, 2023Publication date: August 24, 2023Inventors: Naginder Gogna, Jason Meyer, Rajit Johri, Hao Wang, Ming Cheng, William Frederick Sanderson, JR., Zeng Qiu

Patent number: 11623627Abstract: A vehicle includes a powertrain and a controller. The powertrain has an engine and an electric machine that are each configured to generate power within the powertrain to propel the vehicle. The controller is programmed to, generate a powertrain power output profile required to propel the vehicle over a predetermined route based on navigation data. The controller is further programmed to, in response to the electric machine operating to propel the vehicle over the predetermined route while the engine is shutdown and an upcoming increase in the powertrain power output profile to a value that is greater than a threshold, initiate an engine start at a predetermined time period before the upcoming increase in the powertrain power output profile.Type: GrantFiled: November 12, 2020Date of Patent: April 11, 2023Assignee: Ford Global Technologies, LLCInventors: Walter Joseph Ortmann, Naginder Gogna

Patent number: 11152878Abstract: Systems and methods for improving shifting of a transmission are described. The systems and methods may be applied to automatic or manual transmissions, but the systems and methods may be particularly suited for automatic transmissions. In one example, electrical input to an alternator and electrical output from the alternator is adjusted in response to a request to upshift a transmission.Type: GrantFiled: February 1, 2019Date of Patent: October 19, 2021Assignee: Ford Global Technologies, LLCInventors: Ross Dykstra Pursifull, Naginder Gogna, Joseph Thomas

Patent number: 10876484Abstract: Methods and systems are provided for accurately estimating intake aircharge based on the output of an intake oxygen sensor while flowing EGR, purge, or PCV hydrocarbons to the engine. The unadjusted aircharge estimate is used for engine fuel control while the hydrocarbon adjusted aircharge estimate is used for engine torque control. A controller is configured to sample the oxygen sensor at even increments in a time domain, stamp the sampled data in a crank angle domain, store the sampled data in a buffer, and then select one or more data samples corresponding to a last firing period from the buffer for estimating the intake aircharge.Type: GrantFiled: April 3, 2018Date of Patent: December 29, 2020Assignee: Ford Global Technologies, LLCInventors: Gopichandra Sumilla, James Alfred Hilditch, Ross Dykstra Pursifull, Michael McQuillen, Martin Brown, Imtiaz Ali, Naginder Gogna
