Further, when the preset refueling is set and the refueling is interrupted and the dual-purpose switch 22b is pressed, the preset numerical value is displayed instead of the current refueling data displayed on the display 23, and the refueling is performed. When the operation is restarted or a predetermined time T (5 seconds) elapses, the current refueling data is returned again. Further, when the dual-purpose switch 22b is pressed during refueling with automatic full refueling,
The refueling control unit 33 is instructed to cancel the automatic full refueling and set the free refueling.

The refueling control unit 33 controls the automatic filling tank refueling function and the preset refueling function, receives the refueling permission signal from the nozzle elevation control unit 31, and displays the previous refueling data displayed on the displays 13 and 23. Is returned to zero, the control valve 6 is opened, and if a preset refueling setting signal is received from the dual-purpose switch control unit 32, the numerical value is set.

During refueling, refueling data is calculated from the flow rate pulse of the pulse transmitter 5,
The information is displayed on the displays 13 and 23.

The pump control unit 34 is provided with a nozzle elevation control unit 3
In response to the refueling permission signal from No. 1, a start signal is output to the pump motor 3, and in response to the refueling end signal from the nozzle elevating control unit 31, the start signal to the pump motor 3 is stopped to end the control.

Next, the refueling operation will be described. First, in a state where the refueling nozzle 20 is at the ascending position A, when the operation string 22aa of the elevating switch 22a is pulled, the elevating switch 22a is closed,
The signal is input to the nozzle elevation control unit 31 of the control device 30 (ST1 in FIG. 5). At this time, since the signal from the position sensor 12 is the ascending position A (ST2 in FIG. 5), a forward rotation signal is output to the reel motor 11 (ST3 in FIG. 5), and the reel motor rotates forward to refuel from the hose reel 11. The hose 10 is pulled out. When the refueling nozzle 20 descends to the refueling position B, the signal from the position sensor 12 becomes the refueling position B (ST4 in FIG. 5), the forward rotation signal to the reel motor 11 is stopped, and the refueling control is performed by the nozzle elevation control unit 31. The refueling permission signal is transmitted to the section 33 and the pump control section 34 (FIG. 5, ST5). Then, the refueling nozzle 20 is inserted into the refueling port of the vehicle to perform refueling.

The pump control unit 34, which has received the refueling permission signal from the nozzle elevation control unit 31 (ST1 in FIG. 8), outputs a start signal to the pump motor 3 (ST2 in FIG. 8), and the pump 2 is driven by the pump motor 3. .

On the other hand, the refueling control unit 33 which has received the refueling permission signal from the nozzle elevation control unit 31 (ST1 in FIG. 7) outputs a reset signal to the indicators 13 and 23 and outputs a valve open signal to the control valve 6. (ST2 in FIG. 7), the previous refueling amount displayed on the indicators 13 and 23 returns to zero, and the control valve 6 opens.

When the refueling nozzle is lowered to the refueling position B, the indicator 23 of the refueling operating device 21 indicates that the automatic refueling is full. Then, to perform preset refueling, press the dual-purpose switch 22b before starting refueling (FIG. 6).
ST1), since the refueling has not started yet (ST2 in FIG. 6), as shown in FIG. 4, "automatic" of the automatic full refueling disappears, and "free" in which the automatic full refueling is canceled, the fixed amount preset , The amount of fixed amount preset is “10” liters,..., And again the automatic filling of the tank is displayed as “automatic” (ST3 in FIG. 6). Then, a desired numerical value, for example, “2”
000 "circle, release the dual-purpose switch 22b,
When refueling is started from the refueling nozzle 20 and a flow rate pulse is input from the pulse transmitter 5 of the flow meter 4 to start refueling (FIG. 6)
ST4), the dual-purpose switch control unit 32 transmits the preset refueling setting signal of “2000” circle selected and displayed on the display 23 to the refueling control unit 33 (FIG. 6 ST).
5).

The refueling control section 33 which has received the preset refueling setting signal of "2000" circle (ST3 in FIG. 7) sets this numerical value (ST4 in FIG. 7). And during refueling, the flow meter 4
The flow rate pulse input from the pulse transmitter 5 is calculated by the refueling control unit 33, and the calculated refueling data is displayed on the display 13,
23 is displayed. Refueling is performed in this manner, and when refueling is performed up to the set numerical value (ST5 in FIG. 7), the control valve 6 is closed (ST6 in FIG. 7), and the control ends.

In order to see the numerical values set during the preset refueling, when the refueling is interrupted and the dual-purpose switch 22b is pressed (ST1 in FIG. 6), it is after the refueling is started (ST1 in FIG. 6).
2) Since the preset refueling is being performed (ST6 in FIG. 6) and the refueling is being suspended (ST7 in FIG. 6), the preset numerical value set in place of the current refueling data is displayed on the display 23 (ST8 in FIG. 6). ) Or refueling is resumed (Fig. 6
ST9), after a lapse of a predetermined time T (5 seconds) (FIG. 6)
ST10), erase the preset numerical value (ST1 in FIG. 6).
1) The current refueling data is displayed again.

Before starting refueling (see FIG. 6)
ST1), when the dual-purpose switch 22b is pressed (ST in FIG. 6).
2), as shown in FIG.
3 (ST3 in FIG. 6). Then, when "free" is displayed, release the dual-purpose switch 22b to select it and start refueling (FIG. 6, ST4).
The dual-purpose switch control unit 32 transmits a free refueling setting signal to the refueling control unit 33 (FIG. 6, ST5).

Refueling control unit 3 which has received a free refueling setting signal
3 (ST7 in FIG. 7), set free refueling (FIG. 7
ST8) Refueling is performed. When a refueling end signal is received from the nozzle elevation control unit 31 as described later (see FIG. 7).
ST9), and outputs a valve closing signal to the control valve 6 (ST in FIG. 7).
10), the control valve 6 closes and the control ends.

When refueling is started without pressing the dual-purpose switch 22b, the refueling control section 33 controls refueling with a preset automatic full tank refueling (ST11 in FIG. 7), and the fuel tank of the vehicle is almost completely filled. When the liquid level sensor 24 detects a bubble which is full and rises (ST12 in FIG. 7), a throttle signal is output to the control valve 6 (ST13 in FIG. 7), and the control valve 6 is throttled to the medium discharge amount. Whenever the liquid level is detected by the liquid level sensor 24, the control valve is throttled. When the detection of the liquid level becomes X (three times) (ST14 in FIG. 7), it is determined that the fuel tank is completely filled. 6 to output a valve closing signal (FIG. 7 S
T15), the control valve 6 closes and the control ends.

In order to change the automatic full tank refueling to the free refueling after the refueling is started, when the dual-purpose switch 22 is pressed (ST1 in FIG. 6), after the refueling is started (ST2 in FIG. 6),
Since it is not during the preset refueling (ST6 in FIG. 6) and automatic refueling is in progress (ST12 in FIG. 6), the dual-purpose switch control unit 32 transmits a free refueling setting signal to the refueling control unit 33 (ST13 in FIG. 6).

Then, the refueling control unit 33 receiving the free refueling setting signal from the dual-purpose switch control unit 32 (FIG. 7 S
T7), free refueling is set (ST8 in FIG. 7), and refueling is performed. When the refueling end signal is received from the nozzle elevating control unit 31 (ST9 in FIG. 7), the control valve 6 is closed (ST10 in FIG. 7) to end the control.

When refueling is completed and the up / down switch 22a is pressed, a close signal is input to the nozzle up / down control unit 31 (FIG. 5).
ST1) Since the current position is the refueling position B and the signal from the position sensor 12 is not the ascending position A (ST2 in FIG. 5), a refueling end signal is transmitted to the refueling control unit 33 and the pump control unit 34, and the reel motor 11 is rotated in the reverse direction. Signal (see FIG. 5 ST
6), the refueling hose 10 is wound up on the hose reel 9. When the refueling nozzle 20 moves up to the rising position A, the signal from the position sensor 12 becomes the rising position (see FIG. 5).
ST7), the reel motor 11 stops (ST in FIG. 5).
8), the nozzle elevation control unit 31 ends the control.

As described above, the refueling control unit 33 which has received the refueling end signal from the nozzle elevation control unit 31 (FIG. 7)
ST9), close the control valve 6 and end the control. Further, the pump control unit 34 that has received the refueling end signal from the nozzle elevation control unit 31 (FIG. 8 ST3) stops the start signal output to the pump motor 3 (FIG. 8 ST4), and stops driving the pump 2. To end the control.
