  • Patent number: 11111885
    Abstract: Methods and systems are provided for improving fuel vapor storage canister purging operations for vehicles with dual-path purge systems. In one example, a method may include purging fuel vapors from a fuel vapor storage canister to an engine of a vehicle via a single path, and in response to an unmetered increase in a concentration of the fuel vapors being purged to the engine via the single path, switching the fuel vapors to be purged to the engine via two paths simultaneously. In this way, fuel vapors may be distributed in time along the two paths, which may lower an effective concentration of fuel vapors entering the engine and may thereby avoid degradation of engine operating conditions.

  • Patent number: 11104222
    Abstract: Methods and systems are provided for pinpointing a restriction in a vehicle evaporative emissions system which may adversely impact refueling and/or fuel vapor canister purging operations. In one example a method comprises conducting a diagnostic to identify a location of a restriction based on a rise time at which a pressure in a fuel system of a vehicle rises to a threshold pressure during a refueling event where fuel is added to the fuel system. In this way, a location of the restriction may be identified so as to enable appropriate mitigating action to be taken.

  • Patent number: 11096613
    Abstract: Exemplary embodiments described in this disclosure are generally directed to systems and methods for reducing anxiety in an occupant of a vehicle. In one exemplary method, a computer that is provided in a vehicle receives from a source such as a server computer, information that is used to determine a behavioral profile of an occupant of the vehicle. The computer utilizes the behavioral profile to identify a behavior characteristic of the occupant. The behavior characteristic is matched by the computer to one of various behavior categories such as an amaxophobia sufferer category or a controlling personality category. The computer then executes one or more operations in the vehicle based on the behavior category to which the occupant belongs. If the occupant belongs to the amaxophobia sufferer category, the computer may, for example, play an audio track, display a video clip, and/or change a driving characteristic of the vehicle.

  • Patent number: 11067013
    Abstract: Methods and systems are provided for indicating a restriction in a fuel system vapor recovery line. Responsive to such an indication, methods and systems are provided for taking mitigating actions such that an entirety of a vehicle fuel system and evaporative emissions system, including a fuel filler system, may be diagnosed as to a presence or absence of undesired evaporative emissions, even with the restriction in the vapor recovery line present. In this way, undesired evaporative emissions may be reduced or avoided, completion rates for such tests may be increased, and customer satisfaction may be improved.

  • Patent number: 11034234
    Abstract: Methods and systems are provided for determining an offset of a pressure sensor that is used for monitoring pressure in a fuel system that is sealed expect for refueling and other diagnostic events. In one example, a method includes waking a controller of a vehicle when it is expected that a pressure in a fuel system that is sealed from atmospheric pressure is at atmospheric pressure, unsealing the fuel system, and indicating an offset of the pressure sensor based on a pressure change after the fuel system is unsealed. In this way, pressure sensor offset may be determined regularly without undesirably loading a fuel vapor storage canister with vapors, which may be particularly advantageous for hybrid vehicles.

  • Patent number: 10997803
    Abstract: Methods and systems are provided for conducting a fuel tank diagnostic. In one example, a method comprises sealing a fuel tank of a vehicle, retrieving data related to fuel tank pressure from a crowd of vehicles, and indicating the fuel tank of the vehicle being diagnosed is degraded responsive to data related to fuel tank pressure from the crowd insufficiently correlating with a set of data related to fuel tank pressure from the vehicle. In this way, fuel tank degradation may be indicated without coupling the fuel tank of the vehicle to atmosphere, which may reduce a release of undesired evaporative emissions to atmosphere.

  • Patent number: 10994605
    Abstract: Methods and systems are provided for reducing an amount of fuel vapors that are routed to a fuel vapor storage canister during a refueling event, in response to an indication that a fuel dispenser that is dispensing fuel to a fuel tank is underperforming. In one example, a method comprises increasing a pressure in the fuel tank responsive to an indication that the fuel dispenser is dispensing fuel at a first rate that is at least a threshold amount below a second rate, without changing the first rate at which the fuel dispenser is dispensing the fuel. In this way, fuel vapor recirculation may be improved and an amount of fuel vapors routed to the canister reduced, which may thus reduce opportunities for release of undesired evaporative emissions to atmosphere.

  • Patent number: 10981774
    Abstract: Methods and systems are provided for refueling a vehicle configured with an onboard refueling vapor recovery (ORVR) system, such that a loading of a fuel vapor canister configured to capture and store fuel vapors, is reduced. In one example, during the refueling, a rate at which fuel vapors are routed to the fuel vapor canister is adjusted responsive to an indication that the vehicle is refueling at a gas station equipped with offboard fuel vapor recovery infrastructure. In this way, loading of the fuel vapor canister may be reduced which may prevent undesired bleedthrough emissions resulting from a canister loaded with fuel vapors, particularly in examples where the vehicle is a hybrid vehicle and where engine runtime is limited, thus limiting potential opportunities for purging of the fuel vapor canister.

  • Patent number: 10982607
    Abstract: Methods and systems are provided for diagnosing a vehicle fuel system for a presence or absence of undesired evaporative emissions. In one example, a method comprises evacuating the fuel system of a vehicle to a variable vacuum target as a function of a volatility of fuel in a fuel tank positioned in the fuel system and a loading state of a fuel vapor storage canister configured for capturing and storing fuel vapors from the fuel tank. In this way, analysis of a pressure-bleedup portion of the diagnostic may be more reliable and completion rates of the diagnostic may be improved, while conducting the test in an environmentally fashion.

  • Patent number: 10975782
    Abstract: Methods and systems are provided for conducting an evaporative emissions test diagnostic on a vehicle fuel system and evaporative emissions control system during engine-on conditions. In one example, a first fuel vapor storage device is separated from a second fuel vapor storage device by a one-way check valve, thus preventing loading of the first fuel vapor storage device during conditions such as refueling operations, diurnal temperature fluctuations, or from running-loss vapors from a vehicle fuel tank. In this way, the evaporative emissions test diagnostic may be conducted during a cold-start event where an exhaust catalyst is below a predetermined threshold temperature required for catalytic oxidation of hydrocarbons in the engine exhaust, without increasing undesired exhaust emissions.
