Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 1 illustrates a peripheral configuration diagram of a fuel remaining amount calculator 200 according to an embodiment of the present invention. FIG. 2 illustrates a fuel drain plug, which is an example of the fuel remaining amount sensing unit 100 in FIG. FIG. 3 illustrates a block diagram of the fuel drain plug 100 and the fuel remaining amount calculator 200 in FIG.

The term "fuel remaining amount detection system " used in Fig. 1 and the following description is a concept including the fuel remaining amount detection unit 100 and the fuel remaining amount calculator 200 required to detect the fuel remaining amount in the fuel tank, The digital tacho graph (DTG) 300 can be further defined. The fuel residual quantity sensing unit 100 uses a specially designed fuel drain plug in the embodiment of the present invention. A device or part capable of detecting the flow rate pressure and the temperature of the flow rate in the fuel tank in addition to the fuel drain plug and transferring it to the fuel remaining amount calculator 200 to be described later can also be used as the fuel remaining amount sensing part 100. [

Referring to FIGS. 1 and 2, the fuel remaining amount sensing unit 100 senses at least one of a flow pressure and a flow temperature of a fuel present in a fuel tank, and transmits the sensed fuel to the fuel remaining amount calculator 200. The fuel remaining amount sensing unit 100 may be embodied as a fuel drain plug detachably mountable to a fuel drain port located on the lower surface of the fuel tank as shown in FIG. 3, the fuel drain plug serving as the fuel remaining amount sensing portion 100 for sensing the flow rate pressure or the flow rate pressure and the flow rate temperature,

A pressure sensing sensor 110 for sensing the flow pressure in the vehicle fuel tank,

A temperature sensing sensor 120 for sensing the flow rate temperature in the fuel tank,

An information transfer unit 130 for transferring sensed temperature and pressure information to the fuel remaining amount calculator 200 as an external device,

And a power supply 140 for supplying operating power to detect the remaining amount of fuel in the vehicle fuel tank. A coin battery may be used as the power supply unit 140.

The information transmitting unit 130 may use one of a short range wireless communication unit (Bluetooth, ZigBee, etc.) or a wired (e.g., I2C (Inter Integrated Circuit)) interface unit.

For reference, the pressure sensing sensor 110 and the temperature sensing sensor 120 are mounted in the fuel drain plug, and the sensing unit for sensing the flow pressure and the temperature is exposed at an upper portion of the fuel drain plug. That is, by allowing the sensing unit to be exposed in the hole formed in the upper surface of the fuel drain plug, the flow rate pressure and the flow rate temperature of the fuel introduced into the hole can be sensed. Of course, the temperature sensing sensor 120 may be located in the fuel drain plug. As an alternative embodiment, the fuel drain flap may be provided with only a pressure sensor for sensing the flow rate pressure in the vehicle fuel tank.

If the fuel drain plug detachably attachable to the lower portion of the fuel tank is used as the fuel remaining amount sensing unit 100, the interval in which the horizontal section can not be measured in the fuel tank is reduced to less than 0 to 10%, and the fuel remaining amount can be more accurately detected. In the case of a general fuel sender method, the use of the fuel drain plug is superior in terms of effectiveness, considering that the interval in which the horizontal section can not be measured is in the range of 0 to 20% and 80 to 100%. The fuel drain plug according to the embodiment of the present invention can be used in various general methods (for example, a fuel injection method, a fuel injection method, The fuel remaining amount in the fuel tank can be detected more accurately. Since the detected fuel remaining amount can be corrected using the vehicle tilt information in the fuel remaining amount calculator 200 described later, the overall error rate can be reduced to within 3%.

1, the fuel remaining amount calculator 200 determines the driving state of the vehicle through the vehicle speed and the engine RPM information transmitted from an external device, for example, the DTG 300, Calculates the remaining fuel amount by calculating at least one of the flow rate pressure, the flow rate pressure and the flow rate temperature transmitted from the sensing unit 100 and the vehicle slope information acquired through the slope detection sensor, And may be transmitted to the DTG 300 as an external device or may be transmitted to the DTG 300 as an external device without being stored. The fuel remaining amount calculator 200 is installed in a vehicle structure adjacent to a fuel tank, and can be operated by supplying power from the vehicle at all times. Of course, the operation power may be supplied in accordance with the operation of the vehicle ignition key.

As a deformable embodiment, by integrating the fuel remaining amount calculator 200 according to the embodiment of the present invention with the DTG 300, the DTG 300 can calculate the remaining fuel amount based on the fuel remaining amount calculation method according to the embodiment of the present invention The remaining fuel amount may be calculated and transmitted to the vehicle control server.

Meanwhile, the vehicle driving state is defined as a concept including a waiting state after starting, a driving state, an idle state, and a starting-off state. The fuel remaining amount calculator 200 calculates and stores the remaining amount of fuel when the vehicle is in any one of the vehicle driving state, the idling state, and the starting off state, And transmits the fuel remaining amount and the vehicle driving state information to the DTG 300 as an external device. In some cases, the oil / leak event occurrence information can be further added and transmitted. This will be described later. Of course, the fuel remaining amount calculator 200 may further transmit the trip information and the trip fuel amount to the DTG 300.

The FT (Fuel Tank) monitor or DTG 300 shown in FIG. 1 displays the remaining fuel amount of each vehicle traveling state transmitted from the fuel remaining amount calculator 200. The DTG 300, which is one of the external devices, transmits vehicle speed and engine RPM information to the remaining fuel amount calculator 200 (broadcasting casting) in n seconds (n is a positive real number, for example, 1 second) (Fuel remaining amount and vehicle running state information) and vehicle information together with a fueling or leaking event occurrence information from the fuel remaining amount calculator 200 to a vehicle control server (not shown).

The vehicle control server can be defined as recording and managing the operation record of the vans or vehicles to which the remaining fuel amount calculator 200 is attached and the remaining amount of fuel according to the vehicle operation status in order to prevent illegal supply and demand of the fuel subsidy.

Hereinafter, the configuration of the fuel remaining amount calculator 200 described above with reference to FIG. 3 will be described in more detail.

First, the fuel remaining amount calculator 200 includes an information transmitting unit (for example, BT BLE) 210 for receiving at least one of the flow pressure and the flow temperature from the remaining fuel amount sensing unit 100, The tilt detection sensor 230 for obtaining the vehicle tilt information and the overall operation of the user interface unit 240 and the remaining fuel amount calculator 200 including the buzzer for outputting various indicator lights And a control unit 220 for controlling the operation of the apparatus.

The control unit 220 determines the driving state of the vehicle through the vehicle speed and the engine RPM information transmitted from the DTG 300, and when the vehicle is in the designated driving state, the control unit 220 outputs one of the flow rate pressure and the flow rate temperature transmitted from the remaining fuel amount sensing unit 100 And calculates the remaining fuel amount by calculating one or more values of the vehicle tilt information acquired through the tilt sensor, and stores the calculated remaining fuel amount together with the vehicle running status information and transmits the stored remaining fuel amount to the DTG 300. [ In the system for calculating the remaining fuel amount in the DTG 300, it can be considered that the operation performed by the fuel remaining amount calculator 200 is performed by the DTG 300 in the same manner.

Further, the controller 220 compares the stored remaining amount of fuel with the newly calculated remaining amount of fuel to generate information on the occurrence of oiling or leaking events, and transmits the information together with the remaining amount of fuel.

As a more detailed example, the controller 220 determines the idle state when the vehicle speed is zero and the engine RPM is equal to or greater than the specified RPM (RPM 400), and after the idle state entry or when the idle state duration reaches a predetermined time (for example, Or 5 seconds or 30 seconds), the fuel remaining amount is firstly calculated, the fuel remaining amount is secondarily calculated when the idle state is released, the fueling or leaking event occurrence information is generated, And the second calculated fuel remaining amount to the DTG 300.

The control operation of the controller 220 will be described in more detail with reference to FIG. The control unit 220 of the fuel amount calculation calculator 200 can communicate with the DTG 300 through the UART and the power supply unit 250 receives the power from the vehicle at all times or according to the operation of the ignition key, And supplies it to each part of the remaining amount calculator 200. The information transmission unit 210 may also use the I2C interface unit according to the information transmission unit 130 of the remaining fuel amount sensing unit 100. [

FIG. 4 illustrates an operation flow chart for explaining the operation of the fuel remaining amount calculator 200 according to the embodiment of the present invention, and FIG. 5 illustrates an operation flow of the fuel residual amount calculator 200 according to an embodiment of the present invention. Each of which is an example of the report.

Referring to FIG. 4, the controller 220 of the remaining fuel amount calculator 200, which is always supplied with power, wakes up (step S10) when a certain condition is satisfied in the sleep mode (voltage fluctuation or serial data input).

In the wakeup state, the control unit 220 checks whether the vehicle speed and the engine RPM information are received from the DTG 300 (step S15). The vehicle speed and engine RPM information are broadcast cast from the DTG 300, for example, every one second.

When the vehicle speed and the engine RPM information are received, the control unit 220 determines the vehicle driving state through the vehicle speed and the engine RPM information (S20). For example, if the vehicle speed is zero and the engine RPM is equal to or greater than 400, it is determined that the vehicle is in a standby state after startup, and the remaining fuel amount is calculated according to vehicle driving conditions and stored (S25).

The control unit 220 calculates the fuel pressure and the flow temperature transmitted from the fuel remaining amount sensor 100, that is, the fuel drain plug, and the vehicle tilt information read from the tilt sensor 230 to calculate the remaining fuel amount do. Knowing the flow pressure, you can know the height of the flow rate in the fuel tank. If you know the flow rate temperature, you can calculate the fuel balance considering the thermal expansion coefficient of the fuel. Of course, it is possible to calculate the remaining amount of fuel in the horizontal state by correcting it with the inclination information of the vehicle.

When the remaining fuel amount is calculated, it can be checked at the end of the previous operation to check the occurrence of the oiling or leaking event compared with the stored remaining fuel amount. That is, the controller 220 compares the remaining fuel amount calculated in step S25 with the remaining fuel amount calculated and stored at the end of the previous operation to check occurrence of the oiling or leaking event (step S30).

If there is no oiling or leaking event as a result of the check, the vehicle driving state information (i.e., waiting state after starting) and the calculated remaining fuel amount are transmitted to the DTG 300 via UART communication (step S35) The control unit 220 transmits the vehicle running state information, the fuel remaining amount, and the oiling or leaking event occurrence information together to the DTG 300 (step S40).

The DTG 300 stores the information transmitted from the fuel remaining amount calculator 200 by distinguishing the vehicle driving state by date and time as shown in FIG. 5, and stores the classified information by referring to the oiling or leaking event occurrence information do.

After performing step S35 or step S40, the controller 220 determines whether it is in the start-off state (step S45). Judgment can be made through vehicle speed and engine RPM information. If valid vehicle speed and engine RPM information are received, the process returns to steps S15 and S20 to again determine the vehicle running state.

The controller 220 determines that the vehicle is in an idle state when the vehicle speed is zero and the engine RPM is equal to or more than 400, which is the specified RPM. If the idle state duration or the idle state duration reaches a predetermined time, for example, 2 seconds Or 5 seconds or 30 seconds, the remaining fuel amount is firstly calculated by the above-described method, and the remaining fuel amount is calculated by secondary calculation when the idle state is released (when the speed is generated) to calculate the first calculated fuel amount and the second calculated fuel amount And generates oiling or leaking event occurrence information. If an oiling or leaking event has occurred, the control unit 220 proceeds to step S40 and transmits the vehicle running state information (idle state), the remaining fuel amount, and the oiling or leaking event occurrence information described above together. If the oiling or leaking event has not occurred, .

If the vehicle speed increases after the starting standby state after start-up, it is judged to be running and the remaining fuel amount is not calculated. If the idle state duration is less than the predetermined time (30 seconds), it is also determined that the vehicle is temporarily stopped and the remaining fuel amount is not calculated.

In the wakeup state, the controller 220 repeats steps S15 to S45 to calculate the fuel remaining amount in the start waiting state after starting and the remaining fuel amount in the idle state, and transmits the calculated remaining fuel amount to the DTG 300 The DTG 300 can generate a report in which information as shown in FIG. 5 is recorded. Such a report is a report in a form that can be output to the DTG 300 or the display unit from the vehicle control server.

On the other hand, if the vehicle speed is zero in step S45 and the engine RPM is zero or the vehicle speed and the engine RPM are not received, the controller 220 determines that the engine is in the start-off state and proceeds to step S50 to calculate and store the remaining fuel amount again. Then, the control unit 220 transmits the fuel remaining amount after starting and the remaining fuel amount at the end of the operation, which are calculated first at startup, to the DTG 300 (S55), and enters the sleep mode (S60). The remaining fuel amount calculated and stored in step S50 is used for determining whether the fuel is leaking or leaking when restarting.

The control unit 220 of the fuel remaining amount calculator 200 according to the embodiment of the present invention calculates the fuel remaining amount in the start standby state, the fuel remaining amount in the idle state, and the fuel remaining amount in the start- It is possible to accurately calculate the amount of change in the fuel remaining amount in the fuel tank before and after startup ON / OFF, the amount of change in the remaining amount of fuel in the fuel tank in the idle state, the amount of fuel consumption during operation, and the like.

Therefore, by using the fuel drain plug and the fuel remaining amount calculator 200 according to the embodiment of the present invention, it is possible to conveniently acquire data or information to prevent illegal supply and demand of oil price subsidy. There is an advantage that the remaining fuel amount changed according to the state can be accurately calculated and utilized for vehicle control or vehicle management conveniently.

Although the embodiments of the present invention have been described with respect to the embodiments in which the remaining amount of fuel in the vehicle fuel tank is calculated and stored in a system for storing and transmitting the fuel, the remaining amount of fuel calculator according to the embodiment of the present invention, And the like, so that it is possible to supervise and supervise various vehicles as well as to calculate the fuel consumption amount of the management vehicle. Also, in the embodiment of the present invention, the fuel remaining amount sensing unit and the fuel remaining amount calculator are described as operating as separate modules. However, the fuel remaining amount sensing unit and the fuel remaining amount calculator may be integrated and used in a fuel tank.
