  • Patent number: 10268199
    Abstract: A computer for a vehicle is programmed to receive fuel level data over a period of time during a refueling operation. Based on the fuel level data, the computer determines that fuel flow rate during one portion of the refueling operation is materially reduced relative to other portions of the refueling operation. The computer is programmed to output a failure mode based on the determination.

  • Patent number: 10266048
    Abstract: Methods and systems are provided for diagnosing functionality of a vehicle fuel system and a vehicle evaporative emissions system, and one or more components thereof, subsequent to refueling a vehicle fuel tank, and wherein the refueling event may comprise a remote refueling event. In one example, after completion of the refueling event, the fuel system and evaporative emissions system are sealed from atmosphere and from each other, and pressure is monitored in both the fuel system and evaporative emissions system in order to indicate the presence or absence of undesired evaporative emissions in both the fuel system and evaporative emissions system, and to indicate whether the fuel system is effectively sealed from the evaporative emissions system. In this way, costs associated with vehicle repair may be decreased, and undesired evaporative emissions to the atmosphere may be reduced.

  • Publication number: 20190112991
    Abstract: Methods and systems are provided for cooling an engine by operating an electrically driven intake air compressor. In one example, in response to a determination, based on a measured or inferred engine temperature, that the engine temperature is greater than a threshold temperature, employing the vehicle's electrically driven intake air compressor to route air through a charge air cooler and engine cylinders, while engine spins unfueled. In this way the engine temperature may be reduced even under conditions not normally amenable to engine cooling, such as at idle-stops or when an engine coolant system is degraded.

  • Publication number: 20190105960
    Abstract: Methods and systems are provided for conducting an evaporative emissions test on a fuel system in a vehicle. In one example, in response to a determination, based on the prevailing vehicle and ambient thermal conditions, that altering vehicle height may increase pressure or vacuum build during a pressure or vacuum build phase of an engine off natural vacuum test, employing the vehicle's active suspension to make said height adjustments. In this way the accuracy of engine off natural vacuum testing can be improved, and the conditions under which such testing can be efficaciously conducted increased.

  • Publication number: 20190108693
    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.

  • Publication number: 20190107081
    Abstract: Methods and systems are provided for diagnosing a vehicle fuel system and evaporative emissions system, and for diagnosing components in the evaporative emissions system. In one example, a method comprises activating an electric compressor while an engine that propels a vehicle is not in operation, to evacuate the fuel system and evaporative emissions system, sealing the fuel system and evaporative emissions system responsive to a threshold vacuum being reached during the evacuating, and indicating a presence or absence of non-gross undesired evaporative emissions based on a pressure rise in the sealed fuel system and evaporative emissions system. In this way, sources of undesired evaporative emissions may be readily detected, such that release of undesired evaporative emissions to the environment may be reduced.

  • Patent number: 10253728
    Abstract: Methods and systems are provided for conducting an evaporative emissions test on a fuel system and an emissions control system in a vehicle. In one example, in response to an indication that a vehicle parking condition may result in the isolation of the fuel system from the emissions control system via the unintentional closing of fuel tank valves, a vehicle's active suspension system may be employed in order to level the vehicle a determined amount such that the fuel system isolation issues may be mitigated prior to an evaporative emissions test procedure. In this way, the entire fuel system and emissions control system may be diagnosed for potential undesired emissions, and potential violations of regulatory requirements for evaporative emissions testing may be reduced.

  • Patent number: 10255782
    Abstract: Method and apparatus are disclosed for vehicle flood detection. An example vehicle includes an engine, a humidity sensor, a GPS receiver to determine a vehicle location, a communication module, and a control module. The control module is to collect, via the humidity sensor, a humidity measurement within the engine and collect a humidity level of the vehicle location. The control module also is to identify a flooding event when the humidity measurement exceeds the humidity level by a predetermined threshold and record the flooding event with a remote server via the communication module.

  • Publication number: 20190101072
    Abstract: Methods and systems are provided for including a single pressure sensor in an evaporative emissions system and fuel system. In one example, a method may include venting a fuel tank of the fuel system, which is isolated from the evaporative emissions system by a fuel tank isolation valve (FTIV), in response to a depressurization condition determined based on a differential pressure measured by a delta pressure sensor coupled across the FTIV. The venting may include pulsing the FTIV open and closed and may further include adjusting the pulsing responsive to the differential pressure measured while the FTIV is closed and independent of the differential pressure measured while the FTIV is open.

  • Publication number: 20190093607
    Abstract: Methods and systems are provided for indicating whether a canister purge valve in a vehicle evaporative emissions control system is degraded. In one example, an air intake system hydrocarbon (AIS HC) trap temperature may be monitored during a refueling event, and responsive to an indication that the AIS HC trap temperature change is greater than a predetermined threshold, it may be indicated that the canister purge valve is degraded. In this way, diagnosis of whether a vehicle canister purge valve is degraded may be indicated without the use of engine manifold vacuum, and may be advantageous for vehicles configured to operate for significant amounts of time without engine operation, or without intake manifold vacuum.

  • Patent number: 10233857
    Abstract: A method for a fuel system is provided, wherein a fuel vapor canister is vented to an engine intake during a first condition, and wherein a restriction in a canister vent pathway is indicated, responsive to a change in a fuel tank pressure transducer output greater than a threshold. If the fuel tank pressure transducer output changes less than the threshold, degradation of the fuel tank pressure transducer is indicated. In this way, a fuel tank pressure transducer offset may be distinguished from a canister vent pathway restriction if a fuel tank pressure transducer indicates a significant pressure or vacuum in a fuel tank following a vehicle-off soak.
