摘要: A method for controlling a vehicle includes identifying a user identity associated with a user riding in the vehicle, determining a destination associated with the user identity, creating a detection zone proximate to the vehicle when the vehicle is localized in a first drop-off location associated with the destination, causing a sensory system to identify a hazard within the detection zone and generate a localization of the hazard, determining that a first probability of realizing a risk associated with the hazard is less than a first probability threshold, and generating a vehicle door actuation that permits the user to exit the vehicle based on the first probability of realizing the risk.

摘要: Methods and systems are provided for vehicle fuel tanks including multiple reservoirs. In one example, a method may include opening a canister purge valve of a fuel system responsive to a fuel level of a fuel tank transitioning above a first threshold fuel level, and closing the canister purge valve after flowing a pre-determined amount of fuel to the fuel tank while the canister purge valve is open.

摘要: Methods and systems for determining pressure changes across at least two fuel vapor storage canisters are described. The methods and systems may include determining the pressure changes via a sole pressure sensor. In one example, fuel vapor canister bypass passages are provided to determine pressure values at a plurality of positions within an evaporative emissions system.

摘要: Methods and systems for deicing an engine air intake filter and an engine throttle are described. The methods and systems may include activating an evaporative emissions system heater and a pump to de-ice the engine air intake filter and the engine throttle. The deicing may be performed when an engine of a vehicle is not operating.

摘要: A vehicle and a fuel system for a vehicle are provided. The fuel system has a fuel tank, a fuel fill inlet fluidly connected to the fuel tank to receive fuel dispensed from an external fuel supply device, and a recirculation line with a first end fluidly connected to the fuel fill inlet and a second end fluidly connected to the fuel tank. An ejector is positioned within the recirculation line. A valve fluidly connects the ejector to the fuel tank via a drain line. A method of fueling a vehicle is also provided.

摘要: A vehicle includes a fuel tank and an evaporative-emissions system having a primary subsystem and an auxiliary subsystem. The primary subsystem has a fuel-vapor canister in fluid communication with the fuel tank to capture fuel vapors of the fuel tank. The auxiliary subsystem is configured to capture fuel vapors associated with an external fuel-storage device. The auxiliary subsystem has an auxiliary port located on an exterior of the vehicle and is configured to connect with the external fuel-storage device. The auxiliary port is selectively connected in fluid communication with the fuel-vapor canister by a valve.

摘要: Methods and systems are provided for diagnosing potential degradation of a fuel tank pressure sensor. In one example, a method may include, in response to an ambient pressure reading by the fuel tank pressure sensor during an evaporative emissions (EVAP) system diagnostic, applying vacuum to the EVAP system and indicating degradation of the fuel tank pressure sensor if the canister undergoes an endothermic reaction. If the fuel tank pressure sensor is determined to not be degraded, the method further includes distinguishing between the ambient pressure reading being caused by a leak in the EVAP system and a canister purge valve being stuck closed.

摘要: Methods and systems are provided for indication of a degradation in an EVAP and/or fuel system. In one example, a method for indication of a presence or absence of a degradation in a refueling system may include vacuum pull-down and pressure bleed-up tests being carried out based on a state of submersion of a spud valve in liquid fuel in a fuel tank.

摘要: Methods and systems are provided for diagnosing leaks/degradation in a fuel system. In one example, a system for a vehicle may comprise a variable volume device disposed within a fuel tank; an atmospheric port of the variable volume device fluidly coupled to a vent line upstream of a hydrocarbon sensor housed in the vent line, the vent line coupling a fuel vapor canister to atmosphere; and a controller storing instructions for monitoring output of the hydrocarbon sensor; and generating an indication of a degradation in the variable volume device based on the monitored hydrocarbon sensor. In this way, it is possible to effectively detect a degradation/leak in the variable volume device with minimal specialized components in the fuel system.

摘要: Methods and systems are provided for an evaporative emission control system. In one example, a method may include halting a dispensing of fuel to a fuel tank during a refueling event by increasing a backpressure in the fuel tank. The halt to fuel dispensing may be executed based on one or more of an upcoming fuel vapor canister purge event and an estimated fuel vapor canister loading capacity to determine a predicted canister breakthrough. The predicted canister breakthrough may be compared to a threshold to regulate a refueling volume.
