Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The following describes a vehicle and a fuel tank thereof and a fuel remaining amount detection system of the fuel tank according to an embodiment of the present invention with reference to the drawings.

Example one

Fig. 1 is a schematic structural diagram of a fuel residual quantity detection system of a fuel tank according to an embodiment of the present disclosure. As shown in fig. 1, the fuel remaining amount detection system of a fuel tank according to the present embodiment includes: a fuel flow sensor 11, a fuel quantity display 12 and a controller 13. Wherein, fuel flow sensor 11 sets up on the filler pipe of fuel tank, and fuel flow sensor 11 and oil mass display 12 all link to each other with controller 13.

In the present embodiment, a fuel flow sensor 11 is provided for detecting the amount of fuel added to the fuel tank. The controller 13 is used for detecting the fuel consumption of the engine and determining the residual fuel quantity according to the fuel filling quantity and the fuel consumption; and sends the remaining amount of fuel to the fuel amount display 12. Specifically, when filling the fuel tank, the fuel flow sensor 11 will be able to detect the amount of fuel that is filled into the fuel tank. And the controller 13 may add up the fuel filling amount detected by the fuel flow sensor 11 each time and add up the fuel consumption amount of the engine detected each time when determining the remaining amount of fuel; further, subtracting the added fuel oil consumption from the added fuel oil filling amount to obtain the remaining fuel oil amount in the current fuel oil tank. Since the fuel filling amount and the fuel consumption amount of the engine are less disturbed by the external environment, the controller 13 can accurately determine the remaining amount of fuel in the fuel tank.

Further, the fuel flow sensor 11 and the fuel amount display 12 may be connected to the controller 13 by cables.

Alternatively, the fuel flow sensor 11 and the fuel amount display 12 may be both indirectly connected to the controller 13 through a wireless network. For example, a first receiving unit and a first transmitting unit of wireless signals may be provided in the controller 13; a second sending unit of wireless signals can be arranged in the fuel flow sensor 11 to send information of the fuel filling amount to the controller 13; a second receiving unit of a wireless signal may be provided in the fuel amount display 12 to receive the fuel remaining amount information transmitted from the controller 13.

Further, the system also comprises an alarm which is connected with the controller 13 and is used for giving an alarm when the residual fuel quantity is lower than the preset residual fuel quantity so as to remind a vehicle user to fill the vehicle with oil in time. The alarm may be, but is not limited to, a flashlight or a buzzer.

It should be noted that the fuel flow sensor 11 in the present embodiment may be, but is not limited to, a liquid flow meter. The controller 13 may be an Electronic Control Unit (ECU) in the vehicle, or may be a separately provided controller, such as: a programmable logic controller. When the controller 13 is a separately provided controller, it should be connected to the electronic control unit in the vehicle, such as by a cable, to receive the amount of fuel consumption transmitted from the electronic control unit in the vehicle.

Further, for convenience of display, the controller 13 may convert the remaining amount of fuel into data that is easy to display after determining the remaining amount of fuel in the current fuel tank.

In summary, the fuel remaining amount detection system for the fuel tank provided by the embodiment directly detects the fuel filling amount in the fuel tank and the fuel consumption of the engine, and determines the fuel remaining amount according to the fuel filling amount and the fuel consumption. Because the fuel filling amount and the fuel consumption amount of the engine are less interfered by the external environment, the residual fuel amount in the fuel tank can be accurately measured.

As shown in FIG. 4, a fuel pump 44 is provided in the fuel tank 200, the fuel pump 44 being used to deliver fuel to an engine 46 in the vehicle. Wherein, the fuel pump 44 is connected with the engine 46 through a fuel supply pipe 45 provided in the vehicle; a first end of the oil supply pipe 45 is connected to the fuel pump 44, and a second end of the oil supply pipe 45 is connected to the engine 46; the electronic control unit 43 is connected with the engine 46; the fuel flow sensor 11 is fixedly installed on the oil filling pipe 41 and is connected with the electronic control unit 43 through a first cable 42; one end of the filler pipe 41 is fixedly connected to the fuel tank 200. In addition, in order to facilitate the user of the vehicle to observe the remaining amount of fuel, the fuel amount display 12 may be provided on the dashboard of the vehicle, and the fuel amount display 12 may be connected to the electronic control unit 43 through the second cable 47.

The principle of detecting the remaining amount of fuel in the fuel tank of the vehicle in this embodiment will be described with reference to fig. 4. As shown in FIG. 4, when the oil in the filler tube 41 flows through the fuel flow sensor 11, the fuel flow sensor 11 will be able to detect how much fuel is being injected into the fuel tank 200; further, it sends the detected fuel filling amount to the electronic control unit 43 in the vehicle through the first cable 42, and it should be understood that the electronic control unit 43 here is the controller 13 in the first embodiment described above. When the vehicle is started, the fuel pump 44 pumps oil in the fuel tank 200 into the engine 46 through the fuel supply pipe 45, so that the engine 46 works normally; while the electronic control unit 43 will detect the fuel consumption of the engine 46 in real time. Further, the electronic control unit 43 determines the remaining amount of fuel based on the fuel filling amount and the fuel consumption amount; the remaining amount of fuel is then sent to the fuel indicator 13 via the second cable 47 for display.
