Benefits of technology

[0009] The invention provides a means by which an operator positioned at the fuel fill aperture of a motor vehicle is informed that the fuel tank has been completely filled. The driving distance that can be realized is maximized by indicating to the operator whether the tank has actually been filled to capacity when the automatic shut off by the pump nozzle initially stops the flow of fuel into the tank. If the tank has not been completely filled, the operator can safely add additional fuel to the tank so as to achieve more driving time before another refueling stop is required.
[0010] This invention further provides an immediate indication of the fill status of the fuel tank so as to preclude the operator from having to return to the driver's seat and turn the key in the ignition switch in order to observe the fuel gauge. Returning to the driver's seat is time-con

Example

[0017] Referring to FIG. 1, there is a fuel tank filler assembly 10 equipped with the present invention. A fuel cap cover door II is in an open position revealing the presence of a fuel cap 12 and an indicator 13, located in near proximity to the fuel cap 12 and protected by the fuel cap cover door 11 when the fuel cap cover door 11 is in a closed position.

[0018] Operation of the spontaneous full fuel tank indicator occurs in the following manner. As the vehicle fuel tank is filled., a liquid level sensor positioned in the fuel tank detects the fluid level in the fuel reservoir. A liquid level sensor is commonly present in vehicles to operate the fuel tank gauge located on the dashboard. A variety of liquid level sensors exist, including float switches, space electrodes and capacitance type sensors. When the liquid level sensor detects a fluid level at a maximum position, the indicator 13, coupled with the liquid level sensor, contemporaneously conveys the filled status to the vehi...

Abstract

A spontaneous full fuel tank indicator is disclosed that allows an operator stationed at the fuel fill aperture of a motor vehicle to know when the fuel tank is completely filled. The indicator may be a visual display or an audible alert. The indicator may also be the CPU operation of a vehicle member such as the honking of the horn, flashing of the lights, or operation of the vehicle sound system. Alternatively, the indicator may be a visual, audible or vibratory alert at a key fob. The full fuel tank indicator operates in real-time without requiring a key in the ignition switch. A converter kit is also disclosed by which an existing vehicle may be equipped with a spontaneous full fuel tank indicator.

Description

BACKGROUND OF INVENTION [0001] This invention relates in general to an apparatus for a motor vehicle for the detection of a full fuel tank. In particular, the apparatus provides a real time confirmation detectable at the fuel fill aperture that the fuel tank has been filled to capacity. [0002] Gasoline powered motor vehicles require the periodic addition of fuel to the fuel tank. When adding gasoline to the vehicle, it is common practice to attempt to fill the fuel tank to its capacity so as to maximize the driving distance that can be achieved before the fuel tank is depleted again. In most instances, an operator adds fuel by one of two methods: (1) standing at the vehicle fuel fill aperture to the fill pipe while manually depressing the trigger of a fuel pump nozzle that has been inserted into the fill pipe so as to allow fuel to flow into the gas tank, or (2) initially inserting the fuel pump nozzle into the fuel fill area, depressing the nozzle trigger, and then using a trigger ...
