Abstract
Methods and systems are provided for conducting remote refueling events of a passenger vehicle, and for coordinating said remote refueling events with a fuel tank fill level prior to the remote refueling event, a loading state of a fuel vapor storage device, and current and predicted fuel tank pressure. In one example, an amount of fuel that can be added to the fuel tank without overwhelming a capacity of the fuel vapor storage device is increased responsive to scheduling the remote refueling event to take place at a time when the fuel tank is at a negative pressure, thus resulting in partial purge of the fuel vapor storage device prior to commencing refueling. In this way, environmentally friendly refueling events may be enabled, thus reducing the potential for undesired evaporative emissions during refueling events.
