Patent number: 11623857Abstract: Vehicle fuel fill control systems may anticipate vehicle refueling events in order to control the timing of fuel tank depressurization sequences. In a first embodiment, a global positioning system (GPS) is utilized to anticipate the vehicle refueling event prior to initializing the depressurization sequence. In another embodiment, a camera system is utilized to anticipate the refueling event prior to initializing the depressurization sequence. In yet another embodiment, both the GPS and the camera system may be utilized to anticipate the refueling event. By anticipating refueling events, customer wait time for gaining refueling access may be reduced.Type: GrantFiled: August 25, 2021Date of Patent: April 11, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: David Martin, Brent Edward Sealy, Roshini Venkatesh

Patent number: 11584222Abstract: A vehicle assembly includes, among other things, a fuel inlet conduit configured to receive a fuel dispensing nozzle. The fuel inlet conduit opens to an inlet opening. A guard is configured to move back and forth between a blocking position that prevents insertion of the fuel dispensing nozzle through the inlet opening into the fuel inlet conduit, and an accessing position that permits insertion of the fuel dispensing nozzle through the inlet opening into the fuel inlet conduit.Type: GrantFiled: June 24, 2019Date of Patent: February 21, 2023Assignee: Ford Global Technologies, LLCInventors: David Martin, Roshini Venkatesh, Brent Edward Sealy, Dennis Seung-Man Yang, John Joseph Virga

Patent number: 11425227Abstract: Techniques for identifying certain signals sent over the CAN bus between components of a vehicle are provided herein. Specifically, certain testing maneuvers designed to engage the component of interest are provided to a technician for performing on the vehicle. The messages can be captured from the CAN bus and analyzed, using supervised machine learning algorithms, to isolate the message ids and the byte numbers so that the values of the component of interest may be observed for determining performance metrics. Once identified, these performance metrics may be used to compare with other vehicles or improve the design and performance of the vehicle.Type: GrantFiled: January 30, 2020Date of Patent: August 23, 2022Assignee: Ford Global Technologies, LLCInventors: Sasidhar Hari, Praveen Bhupathiraju, Bernard D.

Patent number: 10982632Abstract: This disclosure is directed to vehicle fuel systems capable of isolating the energy within a fuel tank from the vehicle user. An exemplary fuel system may include a first valve located within a fuel inlet conduit and a second valve located within a vapor recovery recirculation line of the fuel system. The first and second valves may be controlled based on the pressure inside a fuel tank of the fuel system. Fuel may only be transferred into the fuel tank when the fuel tank is within a predefined threshold pressure range. A depressurization sequence of the fuel tank may be automatically initiated when a fuel door of the fuel system is moved to an open position. The positioning of the fuel door may be monitored by a fuel door position monitoring device.Type: GrantFiled: March 5, 2020Date of Patent: April 20, 2021Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: David Scott Martin, Roshini Venkatesh, Brent Edward Sealy, Alan Robert Dona, Dennis Seung-Man Yang

Patent number: 9689298Abstract: A method is provided for monitoring an emission control device coupled to an engine. In one example approach, the method comprises, following a deceleration fuel shut-off (DFSO) duration, indicating degradation of an emission device based on an amount of rich products required to cause a sensor to become richer than a first threshold, the indicating carried out when DFSO duration is greater than a second threshold. The method also comprises an integration which is based on inlet air-fuel ratio, the integration starting only after a pre-catalyst sensor reaches stoichiometry.Type: GrantFiled: October 13, 2014Date of Patent: June 27, 2017Assignee: Ford Global Technologies, LLCInventors: Pankaj Kumar, Imad Hassan Makki, Brent Edward Sealy, Michael Casedy
