  The engine 10 is an intake passage injection (MPI) gasoline engine. The engine 10 is provided with an intake passage 11 that takes air into the combustion chamber of the engine 10. The intake passage 11 is provided with an intake pressure sensor 14 that detects the internal pressure of the intake passage 11. A fuel injection valve 12 that injects fuel into the intake port of the engine 10 is provided downstream of the intake passage 11. A fuel pipe 13 is connected to the fuel injection valve 12 and fuel is supplied.

  The fuel storage unit 20 supplies a fuel tank 21 that stores fuel, a fuel filler port 22 that is a fuel inlet to the fuel tank 21, and fuel from the fuel tank 21 to the fuel injection valve 12 via the fuel pipe 13. A fuel pump 24, a pressure sensor 25 for detecting the internal pressure of the fuel tank 21, and a float valve (not shown) are provided therein, and the flow of fuel from the fuel tank 21 to the fuel evaporative gas processing unit 30 is prevented by the action of the float valve. A fuel cut-off valve 26 for controlling, a leveling valve 27 for controlling the liquid level in the fuel tank 21 during refueling, and an orifice having an inner diameter smaller than the inner diameter of a pipe such as a vapor pipe 38 and a purge pipe 39 described later (for example, φ1.0 mm) And a two-way valve 28 for limiting the amount of fuel supplied when the fuel tank 21 is full of fuel, i.e. It is composed of a fuel quantity detecting device for detecting the amount of fuel shown without the fuel tank 21. Further, the fuel evaporative gas generated in the fuel tank 21 passes from the lower part of the leveling valve 27 to the outside of the fuel tank 21 or from the fuel cut-off valve 26 via the two-way valve 28 and the leveling valve 27. Discharged outside.

The fuel evaporative gas processing unit 30 includes a canister 31, a bypass valve 32, a sealing valve 33, a safety valve 34, an air filter 35, a purge valve 37, a vapor pipe 38, and a purge pipe 39.
The canister 31 has activated carbon inside. Further, the canister 31 is provided with an evaporative gas flow hole 31a through which the fuel evaporative gas generated in the fuel tank 21 or the fuel evaporative gas adsorbed on the activated carbon flows. Further, the canister 31 is provided with an outside air intake hole 31b through which outside air is sucked when the fuel evaporative gas adsorbed on the activated carbon is released. Further, the outside air suction hole 31b is connected so as to communicate one side that prevents entry of dust from the outside with the other side of the air filter 35 that is open to the atmosphere.

  The bypass valve 32 is provided with a canister connection port 32 a connected so as to communicate with the evaporative gas flow hole 31 a of the canister 31. The bypass valve 32 has a vapor pipe connection port 32b connected to the other end of the vapor pipe 38, one end of which is connected to the leveling valve 27 of the fuel tank 21, and one end of the engine 10 to the engine 10. A purge pipe connection port 32c connected to communicate with the other end of the purge pipe 39 connected to communicate with the intake passage 11 is provided. The vapor piping connection port 32b and the purge piping connection port 32c of the bypass valve 32 are connected to a vapor piping 38 and a purge piping 39, respectively. The bypass valve 32 is a normally open type electromagnetic valve that opens in a non-energized state and is in a closed state when a drive signal is supplied from the outside and energized. When the bypass valve 32 is not energized and is open, the canister connection port 32a, the vapor piping connection port 32b, and the purge piping connection port 32c communicate with each other so that the fuel evaporative gas is supplied to the canister 31. This allows inflow and outflow and inflow of air sucked from the air filter 35 into the vapor pipe 38 and the purge pipe 39. Further, when the bypass valve 32 is supplied with a drive signal from the outside and is energized and closed, the canister connection port 32a is blocked, and only the vapor piping connection port 32b and the purge piping connection port 32c are communicated to each other. The flow of fuel evaporative gas into and out of the air 31 and the inflow of air from the air filter 35 to the vapor pipe 38 and the purge pipe 39 are disabled. That is, the bypass valve 32 closes the canister 31 when the valve is closed, and opens the canister 31 when the valve is open.

  The sealing valve 33 is interposed in the vapor pipe 38. The sealing valve 33 is a normally closed electromagnetic valve that closes in a non-energized state and opens when a drive signal is supplied from the outside to be energized. The sealing valve 33 closes the vapor pipe 38 when it is in a non-energized state and is closed, and opens the vapor pipe 38 when a drive signal is supplied from the outside and the valve is open when energized. That is, if the sealing valve 33 is in the closed state, the fuel tank 21 is sealed and the fuel evaporative gas generated in the fuel tank 21 cannot flow out of the fuel tank 21, and the sealing valve 33 is in the opened state. For example, the fuel evaporative gas can flow out to the canister 31.

The safety valve 34 is interposed in the vapor pipe 38 in parallel with the sealing valve 33. The safety valve 34 opens when the internal pressure of the fuel tank 21 rises, and releases the pressure to the canister 31 to prevent the fuel tank 21 from bursting.
The purge valve 37 is interposed in a purge pipe 39 between the intake passage 11 of the engine 10 and the bypass valve 32. The purge valve 37 is a normally closed electromagnetic valve that closes in a non-energized state and opens when a drive signal is supplied from the outside to be energized. The purge valve 37 closes the purge pipe 39 when it is not energized and closed, and opens the purge pipe 39 when a drive signal is supplied from the outside and the valve is open when energized. That is, if the purge valve 37 is in the closed state, the fuel evaporative gas cannot be flowed out from the fuel evaporative gas processing unit 30 to the engine 10, and if it is in the open state, the fuel evaporative gas can be flowed out to the engine 10. .

The display 63 displays the vehicle state. For example, the time from the operation of the fueling lid switch 61 until the fueling lid 23 is unlocked, the stop operation of the fueling lid 23, the open / closed state of the fueling lid 23, etc. Is displayed.
The ECU 50 includes an input / output device, a storage device (ROM, RAM, nonvolatile RAM, etc.), a central processing unit (CPU), a timer, and the like.

The intake pressure sensor 14, the pressure sensor 25, the oil supply lid switch 61, the door opening / closing sensor 62, and the main switch 64 are connected to the input side of the ECU 50, and detection information from these sensors is input.
On the other hand, the fuel injection valve 12, the fuel pump 24, the bypass valve 32, the sealing valve 33, the purge valve 37, the display 63, and the door motor 86 provided in the lid lock mechanism 65 are connected to the output side of the ECU 50.

  The ECU 50 controls the operation of the fuel supply lid 23 and the opening / closing of the bypass valve 32, the sealing valve 33, and the purge valve 37 based on detection information from various sensors, and the inside of the fuel tank 21, the sealing valve 33, and the purge valve 37. The fuel evaporative gas such as the pressure control of the vapor pipe 38 and the purge pipe 39 between them, the adsorption of the fuel evaporative gas to the canister 31 and the outflow of the fuel evaporative gas adsorbed to the canister 31 to the intake passage 11 of the engine 10 It controls the flow.

  In particular, the ECU 50 operates the door motor 86 to release the lock of the fuel supply lid 23 when the fuel supply switch 61 is operated to open the fuel supply lid 23. At this time, the fuel tank 21 detected by the pressure sensor 25 is released. When the internal pressure is higher than the atmospheric pressure by a predetermined value or more, the sealing valve 33 is opened, and the fuel evaporative gas in the fuel tank 21 is caused to flow into the canister 31 so that the pressure is lower than the predetermined value near atmospheric pressure. Then, the door motor 86 is operated to release the lock, and the fuel supply lid 23 is opened.

Next, the fuel filler lid device 70 according to the present invention will be described.
FIG. 2 is a cross-sectional view showing the structure of the fuel filler lid device 70 according to one embodiment of the present invention.
As shown in FIG. 2, the fuel filler lid device 70 of the present embodiment includes a fuel filler lid 23 that is a lid for housing a fuel filler opening 22 provided in the vehicle body of the vehicle, the lid lock mechanism 65 and the door opening / closing described above. A sensor 62 is provided.

The fuel filler opening 22 is disposed so as to protrude into the storage chamber 71 provided in the rear fender 8 of the vehicle. The fuel filler port 22 is normally closed by a fuel cap 72 that is releasably fastened, and a nozzle of a fuel gun is connected at the time of opening to enable fuel supply.
The storage chamber 71 is provided inside an opening 73 provided in the rear fender 8. The housing chamber 71 is surrounded and formed by a housing-like housing housing 74 and a lid-plate-shaped oil supply lid 23 that closes the opening 73 so as to be openable.

  The oil supply lid 23 is rotatably supported by a rotation shaft 76 extending in the vehicle vertical direction inside the rear fender 8 via a rotation shaft bracket 23a. In addition, a spring 75 is provided between the rotary shaft bracket 23 a and the housing case 74, and the spring 75 biases the oil supply lid 23 in the opening direction in a closed position where the oil supply lid 23 closes the opening 73. It is provided as follows.

  A door bracket 80 formed by bending a flat plate is fixed to the oil supply lid 23 at the rear part. The door bracket 80 is disposed so as to be positioned in the storage chamber 71 when the fueling lid 23 is closed, and the left and right wall portions 81 (regulating portions) that are substantially perpendicular to the extending direction of the fueling lid 23 in the cross section and the left and right wall portions 81. The front and rear wall portions 82 are bent perpendicularly rearward from the inner end portion of the oil pipe and extend substantially parallel to the direction in which the oil supply lid 23 extends, and the inclined wall portion 83 is bent approximately 45 degrees from the rear end of the front and rear wall portion 82 and extends inward and forward. And have.

  The lid lock mechanism 65 is provided on the rear side of the housing case 74. The lid lock mechanism 65 includes a rod-shaped door hook 85 (locking portion) supported so as to be movable in the vehicle front-rear direction, the door motor 86 that moves the door hook 85 in the vehicle front-rear direction, and the door hook 85 manually forced. And an emergency lever 87 (forced unlocking portion) that is movable in the front-rear direction. The door opening / closing sensor 62 is configured integrally with the lid lock mechanism 65 and can detect the movement position (protrusion position) of the door hook 85.

The door hook 85 of the lid lock mechanism 65 is configured to be urged toward the front side of the vehicle by a hook return spring 88 and protrude toward the front side of the vehicle, and the front end 85a protrudes into the accommodation chamber 71. When the door motor 86 is energized (ON), the door hook 85 moves toward the vehicle rear side against the bias of the hook return spring 88.
When the refueling lid 23 is closed, the door bracket 85 and the door hook 85 are positioned so that the side surface of the door hook 85 protruding toward the front side of the vehicle is positioned along the outer surface of the front and rear wall portion 82 of the door bracket 80 without any gap. The position is set. Accordingly, at this time, the front and rear wall portions 82 of the door bracket 80 abut against the side surface of the door hook 85, and the opening movement of the oil supply lid 23 is restricted. When the oil supply lid 23 is closed, the energization to the door motor 86 is turned off and the hook return spring 88 urges the front end 85a of the door hook 85 to protrude forward of the vehicle. It is set so as to be in contact with the rear surfaces of the left and right wall portions 81 and to be regulated at a position where the projection amount of the door hook 85 is regulated.

On the other hand, when the door motor 86 is energized and the door hook 85 is moved in the anti-protruding direction, the front end 85a of the door hook 80 moves rearward from the rear end of the front / rear wall portion 82 in the front-rear direction. The length and the movable position of the door hook 85 are set.
FIG. 3 is an explanatory diagram showing the relationship between the position of the door hook 85 and the output signal of the door opening / closing sensor 62.

As shown in FIG. 3, the door opening / closing sensor 62 can output two types of output, a high voltage Hi (second output, for example, battery voltage) and a low voltage Lo (first output, for example, a value slightly larger than 0). It has become.
The door opening / closing sensor 62 has a front end 85a of the door hook 85 as a boundary between a position A slightly forward of the left and right wall portions 81 of the door bracket 80 and a position B slightly forward of the rear ends of the front and rear wall portions 82. When the vehicle is positioned in front of the position A (projecting position), the high voltage Hi is output, and between the position A and the position B (regulated position), the low voltage Lo is output. When located behind the vehicle (position on the opposite side), a high voltage Hi is output. The door opening / closing sensor 62 may output 0 instead of the low voltage Lo. However, by setting the door open / close sensor 62 to the low voltage Lo, it is possible to detect disconnection when the output is 0. Further, the high voltage Hi and the low voltage Lo may be reversed, but the power consumption is reduced by setting the output in the closed state of the refueling lid 23, that is, between the position A and the position B, to the low voltage Lo. Can be reduced.

  4 to 7 are explanatory views showing the relationship between the open / closed state of the fueling lid 23 and the moving state of the door hook 85, FIG. 4 is a state in which the fueling lid 23 is closed, and FIG. 5 is a switch from closing to opening of the fueling lid 23. FIG. 6 shows the state (when the door motor 86 is ON), FIG. 6 shows the refueling lid 23 opening operation, and FIG. FIG. 8 is a time chart showing the transition of the output of the door opening / closing sensor 62 when the oil supply lid 23 is open at the normal time.

  As shown in FIG. 4, when the door motor 86 is OFF, the door hook 85 protrudes to the front side of the vehicle by the hook return spring 88. The amount of protrusion is restricted. At this time, the front end 85a of the door hook 85 is in a restricted position between the position A and the position B, so the output of the door opening / closing sensor 62 becomes a low voltage Lo.

As shown in FIG. 5, the oil supply lid switch 61 is operated to release the lock of the oil supply lid 23, the door motor 86 is turned on, and the front end 85 a of the door hook 85 reaches the vicinity of the rear end portion of the front and rear wall 82 of the door bracket 80. When moving to the vehicle rear side, the front end 85a of the door hook 85 is on the vehicle rear side from the position B, and the output of the door opening / closing sensor 62 becomes a high voltage Hi.
When the front end 85a of the door hook 85 moves backward for a predetermined time (fixed time), the door motor 86 is turned off. At this time, the front end 85a moves rearward of the vehicle from the rear end of the front and rear wall 82 of the door bracket 80. As a result, the door bracket 80 is unlocked by the door hook 85, and the oil supply lid 23 starts to open by the spring 75. Then, as shown in FIG. 6, the front end 85a of the door hook 85 abuts against the inclined wall portion 83 of the door bracket 80 and moves forward with the opening of the fueling lid 23, and the front end 85a of the door hook 85 is moved to the position A. It becomes a regulated position between the position B and the output of the door opening / closing sensor 62 becomes a low voltage Lo.

As shown in FIG. 7, when the oil supply lid 23 is in the open state, the front end 85 a of the door hook 85 is separated from the inclined wall portion 83. Since the door motor 86 is OFF, the door hook 85 is moved to the front side of the vehicle by the hook return spring 88, the leading end 85a is in the protruding position on the front side of the vehicle from the position A, and the output of the door opening / closing sensor 62 becomes the high voltage Hi. Become.
Therefore, when the oil supply lid switch 61 is operated to open the oil supply lid 23, as shown in FIG. 8, the output of the door opening / closing sensor 62 changes in the order of Lo, Hi, Lo, and Hi. At this time, the duration T1 (first predetermined time) of the high voltage Hi when the low voltage Lo changes from the low voltage Lo to the high voltage Hi first is substantially constant because the door motor 86 operates for a predetermined time. It will be time.

Next, operation determination of the emergency lever 87 will be described.
FIG. 9 is an explanatory view showing the movement state of the door hook 85 and the oil supply lid 23 when the lock of the oil supply lid 23 is released by operating the emergency lever 87. FIG. 10 is a time chart showing a transition of the output of the door opening / closing sensor 62 when the lock of the fuel supply lid 23 is released by operating the emergency lever 87.

  Even if the oil supply lid switch 61 is operated to release the lock of the oil supply lid 23 and the door motor 86 is turned on, for example, when the door hook 85 does not move and the oil supply lid 23 does not open due to a failure of the door motor 86, the driver or the like However, the emergency lever 87 is operated to manually unlock the fuel supply lid 23. At this time, the operation time of the emergency lever 87 is longer than the normal operation time of the normal door motor 86 because it is performed until the fuel supply lid 23 is manually opened.

Therefore, when the fuel supply lid 23 is opened, the ECU 50 measures the time Ta during which the output of the door open / close sensor 62 changes from the low voltage Lo to the high voltage Hi and is at the high voltage Hi, and exceeds the operating time T1 by the door motor 86. If it is, the emergency lever 87 can determine that the refueling lid 23 has been unlocked and opened.
In this way, it is possible to detect that the fuel supply lid 23 has been opened by operating the emergency lever 87 based on the output time of the output of the door opening / closing sensor 62.

  By the way, when the output of the door opening / closing sensor 62 maintains the high voltage Hi for a predetermined time (second predetermined time) or longer without operating the fuel supply lid switch 61, the fuel supply is performed contrary to the intention of the driver or the like. It can be estimated that the lid 23 has been opened or that the refueling lid 23 has been left open. Therefore, the ECU 50 closes the fuel supply lid 23 when the output of the door opening / closing sensor 62 maintains the high voltage Hi for a predetermined time (second predetermined time) or longer without operating the fuel supply lid switch 61. Thus, the display 63 has a function of displaying a warning. Further, in the present embodiment, when it is determined that the refueling lid 23 is opened by operating the emergency lever 87 as described above, this warning display is restricted. Accordingly, it is possible to prevent the driver or the like from being confused by giving a warning for closing the refueling lid 23 even though the refueling lid 23 is opened by operating the emergency lever 87.

This is the end of the description of the embodiment of the invention. However, the embodiment of the present invention is not limited to this embodiment.
For example, in the above embodiment, the position of the front end 85a of the door hook 85 is detected by the door opening / closing sensor 62 integrally formed with the lid lock mechanism 65, but the proximity sensor provided separately from the lid lock mechanism 65. You may detect using sensors, such as.

  Moreover, in the said embodiment, although this invention is applied to the fuel filler filler lid apparatus of a closed tank, you may apply this invention to the fuel filler lid apparatus of the tank which is not a closed tank.
