Abstract: A throttle control system for a vehicle includes a controller comprising at least one processor and at least one non-transitory computer-readable medium, a throttle valve movable between valve positions, an input sensor to transmit a target position, and a position sensor configured to detect an instantaneous disposition of the throttle valve at one of the valve positions. The controller executes instructions stored in the at least one non-transitory computer-readable medium. The controller receives the target position signal and the detected position signal. The processor compares the target position signal and the detected position signal to the instructions, selects an output signal, and transmits the output signal to the throttle valve. A first fuzzy control acceleration, a brake deceleration, and a second fuzzy control acceleration based on the output signal are applied to move of the throttle valve toward the target position.

Abstract: A charge port covering assembly includes, among other things, doors moveable between a covering position where the doors block access to a charge port, and an accessing position where the doors permit access to the charge port. A door release assembly includes a portion that tilts in response to movement of a charger toward an engaged position with the charge port to permit movement of the doors to the accessing position. A charge port covering method includes, among other things, blocking access to a charge port using a doors in a covering position, and tilting a portion of a door release assembly with a charger. The tilting permits a transitioning of the doors from the covering position to an accessing position where the charger can couple with the charge port.

Abstract: Methods and systems are provided for nozzle guides for vehicle refueling adapters. In one example, a nozzle guide includes a plurality of protrusions adapted to center a fuel nozzle within the nozzle guide and to reduce a likelihood of over-insertion of the fuel nozzle into the nozzle guide. The nozzle guide may include features such as a rear guard and upper wall adapted to reduce ingression of liquid fuel with fuel vapor flowing from the fuel tank.

Abstract: Methods and systems are provided for a non-linear spring mechanism coupled to a cover element. As an example, a system may comprise: a bar linkage mechanism having a first spring arm coupled to a second pivotable spring arm via a living spring hinge, the second pivotable spring arm having a lower or an equivalent stiffness compared to the first spring arm; an element coupled to at least one of the arms of the bar linkage mechanism. In one example, the element may be a cover cap, swing door or a sliding door. In this way, the linkage mechanism may allow the element to open with ease while providing improved performance in corrosive environments.

Abstract: Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

Abstract: A capless refueling port attached to a fuel tank of a vehicle is presented. In one example, the capless refueling port includes a main opening, an articulating unitary plug mounted within a nozzle chamber of the fuel port, and a drain tube. The articulating plug is configured to partially or fully close an inlet of the drain tube connected to the fuel port during refueling; the articulating plug is further adjusted to open after refueling, allowing the fuel port to dissipate any residual pressure in the nozzle chamber to the atmosphere.

Abstract: Methods and systems are provided for an adapter for a fluid refilling system. In one example, an adapter configured for use with a diesel exhaust fluid (DEF) system may include a first end configured to couple with a DEF refill passage, a second end including an aperture shaped to receive a DEF nozzle, a pivotable door closing the aperture and biased against the aperture by a biasing member, and a magnetic ring positioned within the adapter and downstream of the pivotable door. The pivotable door may be formed of a material permeable to DEF vapors and may include a plurality of vent holes configured to flow vapors from the DEF system to atmosphere.

Abstract: Methods and systems are provided for a coupling system of a turbocharger and emissions control device of a vehicle. In one example, the coupling system may include a chamfer on one or more of the flanges of a turbine housing and a catalyst housing to decrease a distance therebetween.

Abstract: Systems are provided for refueling a fuel tank of a motor vehicle via an insert for a filler pipe. In one example, a system may include an insert coupled to an inner circumference of the filler pipe, the insert including a plurality of projections positioned on an inner circumference of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.
