Abstract
Methods and systems are provided for enabling a vehicle for which a jet pump that functions to transfer fuel from a passive side to an active side of a saddle fuel tank is degraded, to reach a desired destination by the taking of mitigating action. The mitigating action includes conducting a driving maneuver in response to an indication that the jet pump is degraded, the driving maneuver conducted in order to transfer a desired amount of fuel from the passive side to the active side. In this way, a vehicle may reach a desired destination even under circumstances where the vehicle may otherwise be unable to reach the desired destination.
Claims20
A method comprising:
- conducting a driving maneuver in response to an indication that a jet pump that functions to transfer a fuel from a passive side to an active side of a saddle fuel tank that supplies the fuel to an engine of a vehicle is degraded, the driving maneuver including transferring a fuel amount from the passive side to the active side.
A method for a vehicle comprising:
- responsive to an indication that a jet pump that functions to transfer a fuel from a passive side to an active side of a saddle fuel tank is degraded, propelling the vehicle along a route that is predicted to result in a transfer of the fuel from the passive side to the active side to enable the vehicle to reach a desired destination in lieu of the jet pump.
A system for a vehicle, comprising:
- a saddle fuel tank for storing a fuel that includes an active side with a fuel pump that supplies the fuel from the active side to an engine for combustion, and a jet pump that transfers the fuel from a passive side of the saddle fuel tank to the active side;
- an onboard navigation system;
- an autonomous vehicle system;
- and
- a controller with computer readable instructions stored on non-transitory memory that when executed, cause the controller to:
- indicate degradation of the jet pump in response to a first fuel level in the active side decreasing while a second fuel level in the passive side is maintained constant under conditions where both the fuel pump and the jet pump are activated;
- request from the onboard navigation system a plurality of routes and associated destinations for the vehicle, the routes specified to include one or more driving scenarios predicted to result in a transfer of the fuel from the passive side to the active side under conditions where the associated destinations are determined not able to be reached via the vehicle based on the first fuel level in the active side;
- receive a selection as to a desired destination from one of the plurality of routes and associated destinations;
- provide a set of instructions to enable the vehicle to be propelled along a route associated with the desired destination;
- and
- propel the vehicle via the set of instructions along the route associated with the desired destination via the autonomous vehicle system in order to reach the desired destination.
