  As shown in FIG. 3, two communication units (communication units 27-1 and 27-2 in the example of FIG. 3) among the communication units 27-1 to 27-4 are arranged in the interior 11 </ b> A of the automobile 11. The other two communication units (communication units 27-3 and 27-4 in the example of FIG. 3) are arranged on the side surface portion 11B outside the vehicle 11.

  In the example of FIG. 3, the communication unit 27-1 is disposed at the front center of the interior 11 </ b> A of the automobile 11, and the communication unit 27-2 is disposed at the rear center of the interior 11 </ b> A of the automobile 11. -1 and 27-2 may be arranged at any position as long as any position within the vehicle 11A of the automobile 11 is included in any communicable range.

  As described above, the communication units 27-1 and 27-2 are arranged so that any position within the vehicle 11A of the automobile 11 is included in any communicable range. Can perform wireless communication with the portable device 12 existing in the vehicle interior 11A. As shown in FIG. 3, the fuel filler lever 61 is disposed in the vehicle interior 11 </ b> A. Therefore, when the user operates the fuel filler lever 61, the user is present in the vehicle interior 11 </ b> A. Therefore, in such a case, the portable device 12 is placed in the vehicle interior 11A and can perform wireless communication with at least one of the communication units 27-1 and 27-2.

  In the example of FIG. 3, a fuel filler 62 is disposed on the left side of the side surface portion 11 </ b> B of the automobile 11, and a hinge-type lid 62 </ b> A is provided on the side face of the automobile 11 of the fuel filler 62. And the communication part 27-3 is arrange | positioned in the left center so that the range of the vicinity of the fuel filler opening 62 may be made into a communicable range, and the communication part 27-4 is arrange | positioned in the right center of the side part 11B of the motor vehicle 11. However, the communication units 27-3 and 27-4 may be arranged at any position as long as the vicinity of the fuel filler port 62 is included in at least one of the communicable ranges.

  As described above, since the communication units 27-3 and 27-4 are arranged so that at least one of the communicable ranges includes the vicinity of the fuel filler port 62, at least any of the communication units 27-3 and 27-4. However, wireless communication with the portable device 12 existing in the vicinity of the fuel filler port 62 can be performed. When the user holding the portable device 12 unlocks the lid 62 </ b> A by operating the lid 62 </ b> A of the fuel filler opening 62, the user is present in the vicinity of the fuel filler opening 62. Therefore, in such a case, the portable device 12 is carried by the user and exists in the vicinity of the fuel filler port 62, and can perform wireless communication with at least one of the communication units 27-3 and 27-4.

  However, it is convenient if the communicable range is too wide, but even if the user holding the portable device 12 is outside the vicinity of the filler port 62, the user can be aware of the lid 62A of the filler port 62 without being aware of it. There is a disadvantage that the lid 62A may be unlocked by another person who performs the operation. Therefore, the communication unit 27-3 is provided at or near the fuel filler port 62 so that the communicable range of the communication unit 27-3 is only in the vicinity of the fuel filler port 62, and the identification information received by the communication unit 27-3. The lid 62A may be unlocked using only In this case, if the user holding the portable device 12 is not in the vicinity of the fuel filler opening 62, the lid 62A is not unlocked, and unlocking of the lid 62A that is not intended by the user or not noticeable can be prevented.

  Next, with reference to the flowchart of FIG. 4, the unlocking process by the control part 21 of FIG. 2 is demonstrated.

  In step S11, the transmission control unit 51 determines whether an unlocking operation has been detected. When the detection signal is not supplied from the lever operation detection unit 23 or the lid operation detection unit 24, in step S11, the transmission control unit 51 determines that the unlocking operation is not detected, and waits until the detection signal is supplied. To do.

  When a detection signal is supplied from the lever operation detection unit 23 or the lid operation detection unit 24, the transmission control unit 51 determines in step S11 that an unlocking operation has been detected, and the process proceeds to step S12.

  In step S12, the transmission control unit 51 controls the communication units 27-1 to 27-4 and transmits a request signal for requesting transmission of identification information by wireless communication. Thereby, a request signal is transmitted to the portable device existing in the communicable range of the communication units 27-1 to 27-4. The portable device that has received the request signal transmits an answer signal representing the identification information stored in the memory of the portable device by wireless communication.

  In step S13, the identification information extraction unit 52 determines whether the identification information is received by a predetermined communication unit. Specifically, when the unlocking operation is detected by the lever operation detection unit 23, the identification information extraction unit 52 receives the answer signal representing the identification information by the communication unit 27-1 or 27-2. In step S13, it is determined that the identification information has been received by a predetermined communication unit, and in step S14, the authentication unit 53 performs an authentication process. That is, when the unlocking operation is detected by the lever operation detection unit 23, since the legitimate portable device 12 should be present in the vehicle interior 11A, the communication unit 27-1 or 27-2 that makes the vehicle interior 11A within the communicable range. When the answer signal represented by the identification information is received, authentication processing is performed.

  When the unlocking operation is detected by the lid operation detection unit 24, when the answer signal indicating the identification information is received by the communication unit 27-3, the identification information extraction unit 52 performs predetermined communication in step S13. It is determined that the identification information has been received by the unit, and an authentication process is performed in step S14. That is, when the unlocking operation is detected by the lid operation detection unit 24, the legitimate portable device 12 should be present in the vicinity of the fuel filler port 62, and therefore the communication unit 27 that makes the vicinity of the fuel filler port 62 a communicable range. When the answer signal represented by the identification information is received in step -3, authentication processing is performed.

  After the processing in step S14, in step S15, the unlock control unit 54 determines that the portable device that transmitted the identification information is a valid portable device 12 based on the result of the authentication processing in step S14 supplied from the authentication unit 53. Determine if authenticated. When it determines with having been authenticated by step S15, in step S16, the unlocking control part 54 controls the lock system 22, and unlocks the lid | cover 62A of the fuel filler opening 62 of the motor vehicle 11. FIG. Then, the unlocking process ends.

  On the other hand, when the unlocking operation is detected by the lever operation detection unit 23 and the answer signal indicating the identification information is not received by the communication unit 27-1 or 27-2, or the unlocking operation is performed by the lid operation detection unit 24. When the operation is detected and the answer signal indicating the identification information is not received by the communication unit 27-3, in step S13, the identification information extraction unit 52 does not receive the identification information in the predetermined communication unit. Determination is made, and the process proceeds to step S17. If it is determined in step S15 that the portable device that has transmitted the identification information is not authenticated as a valid portable device 12, the process proceeds to step S17.

  That is, when the identification information is not transmitted from the legitimate portable device 12, the lid 62A of the fuel filler port 62 is not unlocked and the process proceeds to step S17.

  In step S17, the warning unit 55 determines whether the continuous period of the unlocking operation detected in step S11 is equal to or longer than a predetermined period. When it is determined in step S17 that the continuous period of the unlocking operation is equal to or longer than the predetermined period, in step S18, the warning unit 55 controls the output unit 25 and outputs warning information. That is, since it takes a certain amount of time to open the lid 62A of the fuel filler port 62, the identification information is not transmitted from the legitimate portable device 12, and the unlocking operation is continuously performed for a predetermined time or more. In this case, it is determined that an unauthorized person is trying to unlock the lid 62A of the fuel filler port 62, and warning information is output. Then, the unlocking process ends.

  On the other hand, when it is determined in step S17 that the continuous period of the unlocking operation is not longer than the predetermined period, the unlocking process ends.

  In FIG. 4, the request signal for requesting identification information is transmitted from all of the communication units 27-1 to 27-4. However, the request signal may be transmitted from the communication unit corresponding to the detection signal. . In this case, the transmission control unit 51 transmits request signals from the communication units 27-1 and 27-2 according to the detection signal from the lever operation detection unit 23, and communicates according to the detection signal from the lid operation detection unit 24. A request signal is transmitted from the unit 27-3.

  Further, the following may be performed. The transmission control unit 51 transmits a request signal from the communication unit 27-3 in response to the detection signal from the lid operation detection unit 24. As a result, if the identification information has not been transmitted from the legitimate portable device 12, the transmission control unit 51 either the communication unit 27-1 or 27-2, or the communication units 27-1 and 27-2. -2 transmits a request signal from both. In this way, for example, when the clerk of the gas station operates the lid 62A while the driver holding the portable device 12 is sitting in the driver's seat, the driver performs any operation. The lid 62A of the fuel filler port 62 can be unlocked without the need. As a result, the convenience for the driver is improved.

  As described above, in the unlocking system 10, the lid 62 </ b> A is unlocked so that the lid 62 </ b> A of the fuel filler opening 62 is unlocked when the automobile 11 authenticates the portable device that has transmitted the identification information as the valid portable device 12. Therefore, it is possible to prevent a person other than an authorized user of the automobile 11 who has the portable device 12 from unlocking the lid 62A. As a result, theft of fuel can be prevented. Furthermore, the thief of the car 11 cannot refuel after the theft, and if the cover 62A is destroyed at the gas station or the like after the theft, the car 11 will be notified that the car 11 is a stolen car. Therefore, the theft of the automobile 11 itself can be prevented.

  Further, in the unlocking system 10, when the automobile 11 detects the unlocking operation, a request signal is transmitted, and the portable device 12 transmits an answer signal indicating identification information corresponding to the request signal. Does not need to constantly send an answer signal representing identification information. Therefore, an increase in power consumption of the portable device 12 due to the automobile 11 performing the authentication process can be suppressed.

  Furthermore, in the unlocking system 10, the automobile 11 detects not only the operation on the fuel filler lever 61 but also the operation on the lid 62 </ b> A of the fuel filler 62. For example, the portable machine 12 is held at a self-service gas station. Even if the user forgets to operate the fuel filler lever 61 and stands in front of the fuel filler 62, the user returns to the vehicle interior 11 </ b> A again and does not operate the fuel filler lever 61 with respect to the lid 62 </ b> A. By operating, the lid 62A can be unlocked. As a result, the convenience of operation is improved.

<2. Second Embodiment>
FIG. 5 is a block diagram showing a configuration example of the second embodiment of the unlocking system to which the present invention is applied.

  Of the configurations shown in FIG. 5, the same configurations as those in FIG. The overlapping description will be omitted as appropriate.

  The configuration of the automobile 101 of the unlocking system 100 in FIG. 5 is mainly provided with a control unit 121 instead of the control unit 21 and a communication unit 122 instead of the communication units 27-1 to 27-4. This is different from the configuration of FIG. 5 mainly includes a control unit 131 instead of the control unit 31, a communication unit 132 instead of the communication unit 33, and a new input unit 133. 1 is different from the configuration of FIG.

  In detail, the control part 121 of the motor vehicle 101 of FIG. 5 is comprised by ECU, for example like the control part 21 of FIG. The CPU of the control unit 121 controls the overall operation of the automobile 101 by developing and executing a program stored in the ROM on the RAM.

  For example, the control unit 121 performs authentication processing by comparing the identification information transmitted together with the instruction for unlocking the lid of the fuel filler port by wireless communication with the identification information 26 </ b> A stored in the storage unit 26. Further, the control unit 121 controls the lock system 22 based on the result of the authentication process and the presence / absence of a detection signal from the lever operation detection unit 23 or the lid operation detection unit 24.

  The communication unit 122 is disposed inside or outside the automobile 101 and performs wireless communication using UHF. The communicable range of the communication unit 122 is wider than the communication units 27-1 to 27-4 that transmit request signals using LF, and is transmitted from the portable device 102 that is located relatively far away using UHF. Information can be received.

  The control unit 131 of the portable device 102 is configured by a microcomputer, and the CPU controls the overall operation of the portable device 102 by developing and executing a program stored in the ROM on the RAM. For example, the control unit 131 controls the communication unit 132 according to a command from the input unit 133, and uses the identification information 32 </ b> A of the portable device 102 stored in advance in the memory 32 together with an instruction to unlock the lid of the fuel filler port. Send.

  The communication unit 132 performs wireless communication using UHF. The communicable range of the communication unit 132 is wider than that of the communication unit 33, and information can be transmitted to the automobile 101 that exists relatively far away. The input unit 133 includes operation buttons and the like, receives an operation from the user, and supplies a command corresponding to the operation to the control unit 131. For example, the input unit 133 accepts an operation from the user, and supplies a command for transmitting the identification information 32 </ b> A to the control unit 131 as a command corresponding to the operation together with an instruction to unlock the lid of the fuel filler opening.

  As described above, in the unlocking system 100 of FIG. 5, the automobile 101 can receive information from the portable device 102 that exists relatively far away, so that a user who is away from the automobile 101 can By remotely operating the portable device 102, it is possible to instruct the unlocking of the fuel filler lid. Thereby, for example, even when the user forgets to unlock the fuel filler at a gas station or the like and moves to a remote location, the user can unlock the filler lid and cause the clerk to refuel. It becomes possible.

  FIG. 6 shows a configuration example of a function for controlling unlocking of the fuel filler lid of the automobile 101 by the control unit 121 of FIG.

  In FIG. 6, the control unit 121 includes an authentication unit 53, an identification information acquisition unit 151, and an unlock control unit 152. In FIG. 6, the same components as those in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted because it will be repeated.

  The identification information acquisition unit 151 acquires the identification information received together with an instruction to unlock the lid of the fuel filler port from the portable device existing in the communicable range of the communication unit 122 by the communication unit 122 and supplies the identification information to the authentication unit 53. .

  The unlock control unit 152 controls the lock system 22 based on the result of the authentication process supplied from the authentication unit 53 and the presence / absence of a detection signal supplied from the lever operation detection unit 23 or the lid operation detection unit 24. Thus, the unlocking of the lid of the fuel filler opening of the automobile 101 is controlled.

  Next, the unlocking process by the control unit 121 in FIG. 6 will be described with reference to the flowchart in FIG.

  In step S <b> 31, the identification information acquisition unit 151 determines whether or not the unlocking of the filler opening lid has been instructed. When the communication unit 122 has not received an instruction to unlock the fuel filler lid from the portable device within the communicable range of the communication unit 122, the identification information acquisition unit 151 unlocks the fuel filler lid in step S31. Is determined not to be instructed, and the communication unit 122 waits until an instruction to unlock the fuel filler cap is received.

  When the communication unit 122 receives an instruction to unlock the filler opening lid, in step S31, the identification information acquisition unit 151 determines that the unlocking of the filler opening lid is instructed, and the instruction is received together with the instruction. The identification information is supplied to the authentication unit 53. In step S <b> 32, the authentication unit 53 performs authentication processing using the identification information supplied from the identification information acquisition unit 151 and supplies the result to the unlock control unit 152.

  In step S <b> 33, the unlock control unit 152 determines whether the portable device that has transmitted the identification information is authenticated as a valid portable device 102 based on the result of the authentication process supplied from the authentication unit 53. If it is determined in step S33 that authentication has been performed, in step S34, the unlock control unit 152 determines whether an unlock operation has been detected.

  When the detection signal is not supplied from the lever operation detection unit 23 or the lid operation detection unit 24, in step S34, the unlock control unit 152 determines that the unlocking operation is not detected, and the process proceeds to step S35.

  In step S <b> 35, the unlock control unit 152 determines whether or not a predetermined time has elapsed since the communication unit 122 received an instruction to unlock the fuel filler cap. If it is determined in step S35 that the predetermined time has not elapsed since the instruction to unlock the fuel filler cap was received, the process returns to step S34, and the lever operation detection unit 23 or the lid operation detection unit 24 is returned. Steps S34 and S35 are repeated until a predetermined time elapses after the detection signal is supplied or the instruction to unlock the filler lid is received.

  When the detection signal is supplied from the lever operation detection unit 23 or the lid operation detection unit 24, in step S34, the unlock control unit 152 determines that the unlocking operation has been detected, and the process proceeds to step S36. In step S <b> 36, the unlock control unit 54 controls the lock system 22 to unlock the lid of the fuel filler port of the automobile 101. Then, the unlocking process ends.

  On the other hand, if it is determined in step S35 that the predetermined time has elapsed, the lid of the fuel filler opening is not unlocked, and the unlocking process ends. In addition, even when the portable device that has transmitted the identification information in step S33 is not authenticated as the valid portable device 102, the lid of the fuel filler opening is not unlocked, and the unlocking process ends.

  As described above, in the unlocking system 100, the unlocking operation is performed within a predetermined time when the portable device that has transmitted the instruction to unlock the fuel filler cap is the valid portable device 102 corresponding to the automobile 101. Since the lid of the fuel filler opening is unlocked, it is possible to prevent a person other than a human being authorized by the authorized user of the automobile 101 carrying the portable device 102 from unlocking the lid 62A. As a result, theft of fuel can be prevented. Furthermore, the thief of the car 101 cannot refuel after theft, and if the cover 62A is destroyed at the gas station or the like after the theft, the car 101 is informed to the surrounding that the car 101 is a stolen car. Therefore, the theft of the automobile 101 itself can be prevented.

  Further, in the unlocking system 100, since the portable device 102 transmits the identification information in response to the user's operation on the input unit 133, the portable device 102 does not need to constantly transmit the identification information. Therefore, an increase in power consumption of the portable device 102 due to the automobile 101 performing the authentication process can be suppressed.

  In addition, locking and unlocking of the lid of the filler port can be performed using, for example, an electromagnetic lock mechanism provided in the rear surface of the lid of the filler port or in the vehicle of the automobile 11 (101). In this case, the crime prevention effect can be enhanced because the lid of the filler opening cannot be easily opened in a short time.

  Further, the present invention can be applied to a vehicle provided with a fuel filler opening such as a two-wheeled vehicle, a four-wheeled vehicle, a buggy, and a snow vehicle.

  Furthermore, the embodiments of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the embodiment of the present invention may be an embodiment in which both the first embodiment and the second embodiment described above are combined.

  The unlocking system described above may share a system with a so-called passive entry system for automobiles. In addition, the passive entry system for automobiles refers to unlocking or locking an automobile door when the portable machine is authenticated by a transmission / reception between a portable machine held by a driver and a control unit provided in the automobile. System.

  When the unlocking system described above shares the system with the passive entry system for automobiles, for example, the control units 21 and 121 to which the control function of the passive entry system is added are shared as the control units of both systems. For example, the communication units 27-1 to 27-4 and 122 also perform communication for the passive entry system, so that the communication units 27-1 to 27-4 and 122 are shared as the communication units of both systems.

  Furthermore, for example, the input unit 133 also functions as an operation button for door unlocking and an operation button for door locking, so that the input unit 133 is shared as an input unit for portable devices of both systems. In this case, for example, the input unit 133 identifies whether the operation from the user is an operation for the fuel filler port or the door based on the length of the operated time. In addition, when the operation is performed in a predetermined order (for example, the door locking operation is performed twice after the door unlocking operation), the operation is identified as the operation for the fuel filler port. You may make it identify that there exists.

Further, the recording medium for recording the program executed by the control units 21, 31, 121, 131 may be composed of a built-in ROM, or a program distributed to provide the program to the user is recorded. Magnetic disk (including flexible disk), optical disk (including compact disc-read only memory (CD-ROM), DVD (digital versatile disk)), magneto-optical disk (including MD (mini-disc)), or semiconductor You may comprise by the package media which consist of memory etc. When a recording medium for recording a program executed by the control units 21, 31, 121, 131 is configured by a package medium, the program is installed in the storage unit 26 or the memory 32 and executed.

  In the present specification, the step of describing the program recorded on the recording medium is not limited to the processing performed in time series according to the described order, but of course, it is not necessarily performed in time series. Or the process performed separately is included.
