Description

  For example, the present invention relates to a vehicle-mounted device used in an ETC system (Electronic Toll Collection system).

Conventionally, an ETC system in Japan is an IC card (so-called ETC card) that stores ETC on-board equipment that collects tolls by way of two-way wireless communication with on-road devices installed on the road, and information on toll settlement for settlement. (For example, refer to Patent Document 1). Such a type using an ETC card is called a two-piece type. The on-board unit and the ETC card are separately provided because the toll payment information is stolen together with the on-board unit, and another person misuses the stolen toll payment information to perform toll payment This is to prevent this. That is, in the configuration in which the information for toll payment is always stored in the in-vehicle device body, the person who stole the in-vehicle device body can misuse the toll payment information and perform the toll fee payment illegally. If the card is not used, the in-vehicle device cannot be used.
JP 2000-99784 A

By the way, since the vehicle-mounted device body so far can be used only by one vehicle, a person who owns a plurality of vehicles has to purchase a plurality of vehicle-mounted device bodies.
In consideration of convenience for a person who owns a plurality of vehicles, it is preferable that a single vehicle-mounted device body can handle a plurality of vehicles.

  Such situations and problems are not limited to toll road toll payments using the ETC system, but credit cards, prepaid cards and other IC cards can be used for drive-through shopping, gas stations, This also occurs in the case of an automatic fee settlement system in which fee settlement for a pay parking lot or the like is performed electronically by two-way communication between an on-vehicle device and a road device.

  This invention is made | formed in view of such a subject, and it aims at providing the onboard equipment which can be utilized for a some vehicle by one onboard equipment main body.

  The vehicle-mounted device according to claim 1 (ETC vehicle-mounted device 1 in the embodiment. In the following, the reference numerals of the constituent elements in the embodiment are shown in parentheses), the main body side control means (12) for executing various controls, the main body side The vehicle-mounted device body (2) having the communication unit (10) and the body-side storage unit (13, 14), the vehicle-mounted device body (2) fixed to the vehicle and detachably held, and performing various controls. A holder-side control means (112), a holder-side communication means (110), and a vehicle-mounted device holder (3) having a holder-side storage means (114).

  The holder-side storage means stores a holder ID, which is identification information unique to the vehicle-mounted device holder, and the main-unit-side control means includes vehicle information acquired from the outside of the on-vehicle device at the time of setup, and main-unit-side communication means. And the holder ID acquired from the in-vehicle device holder via the holder-side communication means are associated with each other and stored in the main body-side storage means. Here, the main body side storage means can store a plurality of sets of vehicle information and holder IDs in association with each other. For example, when three vehicles are owned, if the vehicle information is A, B, and C, and the holder ID of the vehicle-mounted device holder fixed to each vehicle is α, β, and γ, Stores the correspondence relationship of vehicle information A-holder IDα, vehicle information B-holder IDβ, and vehicle information C-holder IDγ.

  Then, the main body side control means determines whether or not the vehicle information corresponding to the holder ID acquired from the in-vehicle device holder is stored in the main body side storage means, and if it is stored, the predetermined information using the vehicle information is used. Make the process ready. The predetermined process using the vehicle information is, for example, a process for using the ETC system.

  With such a configuration, for a user who owns a plurality of vehicles, as long as the vehicle-mounted device holders for the number of vehicles are fixed to each vehicle, it is only necessary to have one kitchen for the vehicle-mounted device body. A single vehicle-mounted device can be used.

  The main body side communication means and the holder side communication means may be, for example, a wireless communication means or a wired communication means. However, if the in-vehicle device of the present invention is applied to, for example, an ETC on-vehicle device, it is necessary to perform wireless communication with a road device installed at a toll gate on a toll road. The main body includes wireless communication means. Therefore, if communication between the in-vehicle device body side and the in-vehicle device holder side is also realized by wireless communication, the in-vehicle device body communicates with the outside through the same wireless communication means possessed by the in-vehicle device body. Communication with the container holder can be performed.

  Further, as shown in claim 2, the vehicle-mounted device main body may have notification means for notifying the user, and the fact that it is not set up may be notified via the notification means. That is, when the vehicle information corresponding to the holder ID acquired from the vehicle-mounted device holder is not stored in the main body side storage means, the main body side control means is configured to notify that it is not set up via the notification means. It is. In this way, when there is an in-vehicle device holder in which the vehicle information and the holder ID are not associated with each other, the user or the like notices that the setup is not performed, so that the setup process can be promoted. .

  As described above, according to the vehicle-mounted device of the present invention, the vehicle-mounted device holder is used while being fixed to the vehicle, but the vehicle-mounted device main body is configured to be detachable from the vehicle-mounted device holder. In other words, instead of fixing the OBE main body in a non-removable state with respect to the vehicle, the OBE main body is configured to be detachable from the vehicle. The possibility to come out comes out. If the stolen in-vehicle device body is illegally used, the user will suffer an economic disadvantage.

  Therefore, the vehicle-mounted device according to claim 3 is configured to supply power for operating the vehicle-mounted device main body from the vehicle-mounted device holder. Naturally, it is necessary to supply power to execute various processes in the OBE main unit. However, in this case, if the configuration is to supply power from the OBE holder to the OBE main unit, use the OBE main unit alone. This is preferable from the viewpoint of preventing unauthorized use.

  However, even if it is such a structure, if power supply will be continued in the state which mounted the onboard equipment main body to the onboard equipment holder, illegal use will be invited. Therefore, the vehicle-mounted device holder (3) is configured to have mounting detection means (115) for detecting whether or not the vehicle-mounted device main body is mounted, and the holder-side control means executes the following control. I did it. That is, when it is detected by the mounting detection means that the OBE main body is mounted, power supply to the OBE main body is started, and the holder side is performed via the main body side communication means and the holder side communication means. If it is determined to be valid based on the validity determination result obtained by comparing the identification information stored in the storage means with the identification information stored in the main body side storage means, the power supply to the vehicle-mounted device main body is continued. If it is determined that it is not valid, the power supply to the vehicle-mounted device body is stopped.

  In this way, even if power supply is once started, if it is determined that the verification by the identification information is not valid, the power supply to the vehicle-mounted device body is stopped, so that unauthorized use can be prevented. it can.

  In addition, when the power supply to the vehicle-mounted device main body is stopped in this way, the vehicle-mounted device main body cannot be used, but the fact may be notified by the vehicle-mounted device main body. In that case, as shown in claim 4, the vehicle-mounted device main body (2) has notifying means (18, 19) for notifying the user, and the main body side control means executes the following control. To do. That is, based on the validity determination result by collation between the holder ID stored in the holder side storage means and the holder ID stored in the main body side storage means, which is performed through the main body side communication means and the holder side communication means, If it is determined that it is not valid, the fact that the vehicle-mounted device main body cannot be used is notified via the notification means. This notification means may be notified by voice or may be displayed and notified. It is necessary to pay attention to the following points as the notification timing. That is, when the power supply to the vehicle-mounted device main body is stopped, the vehicle-mounted device main body cannot be used, so it is necessary to notify before the power supply is stopped.

  When a person who has been illegally acquired due to theft or the like uses it, the above notification is not necessary, but even an authorized user may accidentally attach another person's OBE to the OBE holder of his / her own vehicle. It is also assumed that. Therefore, if the user is informed that it is worn by mistake, the user can recognize that fact.

  If only the OBE main body is stolen, it can be handled by the validity judgment based on the verification of the identification information as described above, but if the OBE holder and the OBE main body are stolen as a set, the identification information Unauthorized use cannot be avoided only by collation. Therefore, it is conceivable to weight the password verification as shown in claim 5.

  That is, the vehicle-mounted device according to claim 5 is the vehicle-mounted device according to claim 1 or 2, wherein the vehicle-mounted device holder (3) detects whether or not the vehicle-mounted device body is mounted. )have. Moreover, it is comprised so that the electric power for operating an onboard equipment main body (2) may be supplied from an onboard equipment holder. Furthermore, either one of the vehicle-mounted device main body or the vehicle-mounted device holder has password receiving means (117) for receiving a password input from the user, and the password receiving means within the main body side storage means or the holder side storage means. The storage means existing in the device that does not have the password stores the password. Further, the holder side control means executes the following control. That is, when the mounting detector detects that the vehicle-mounted device body is mounted, the power supply to the vehicle-mounted device body is started, and the holder-side memory is performed via the body-side communication device and the holder-side communication device. The validity judgment result by collation between the identification information stored in the means and the identification information stored in the main body side storage means, and the password received by the password receiving means and the main body side storage means or the holder side storage means in the holder side storage means If it is determined that the identification information is valid and the password is valid based on the result of the validity judgment based on the comparison with the stored password, the power supply to the vehicle-mounted device is continued, and either one is not valid. When it is determined, the power supply to the vehicle-mounted device body is stopped.

  In this way, even if the in-vehicle device holder and the in-vehicle device main body are stolen as a set, the power supply is stopped unless a password is input, so that unauthorized use can be prevented more appropriately.

  In this case as well, the vehicle-mounted device body may be notified that the power supply to the vehicle-mounted device body is stopped and the vehicle-mounted device body cannot be used. In that case, as shown in claim 6, the vehicle-mounted device main body has notification means (18, 19) for notifying the user, and the main body side control means executes the following control. That is, the validity determination result by comparing the identification information stored in the holder-side storage unit with the identification information stored in the main-unit storage unit, and the password, which are performed via the main body-side communication unit and the holder-side communication unit When it is determined that either the identification information or the password is not valid based on the result of the validity determination by comparing the password received by the receiving means with the password stored in the main body side storage means or the holder side storage means Notifies the fact that the vehicle-mounted device main body is unusable via the notification means.

  Embodiments to which the present invention is applied will be described below with reference to the drawings. The embodiment of the present invention is not limited to the following embodiment, and can take various forms as long as they belong to the technical scope of the present invention.

[Description of ETC OBE 1]
The ETC onboard equipment 1 of this embodiment is demonstrated with reference to FIG.1 and FIG.2. FIG. 1 is an explanatory diagram showing a schematic configuration of an in-vehicle device body 2 and an in-vehicle device holder 3 constituting the ETC on-vehicle device 1, and FIG. 2 is an explanatory diagram showing an electrical configuration of the on-vehicle device body 2 and the on-vehicle device holder 3. .

(Shape configuration of the vehicle-mounted device body 2 and the vehicle-mounted device holder 3)
As shown in FIG. 1, the ETC onboard equipment 1 is comprised from the onboard equipment main body 2 of the substantially plate shape which has fixed thickness, and the onboard equipment holder 3 which hold | maintains the onboard equipment main body 2 so that attachment or detachment is possible. The in-vehicle device holder 3 is configured in a shape having an internal space in which the in-vehicle device body 2 can be attached and detached, and is fixed to a vehicle (not shown), and is used for installing the on-vehicle device body 2 in the vehicle.
A mounting detection convex portion 31 is provided on the inner bottom surface of the in-vehicle device holder 3 (the inner surface on which the tip of the in-vehicle device body 2 abuts when the on-vehicle device body 2 is inserted) 3a. The mounting detection convex portion 31 is configured to sink into the in-vehicle device holder 3 when pressed, and when the mounting detection convex portion 31 sinks, the mounting detection portion 115 shown in FIG. It can be detected that the vehicle-mounted device body 2 is mounted.

  Further, the interval between the inner side surfaces of the OBE holder 3 (the inner surface with which the side surface of the OBE main body 2 abuts when the OBE main body 2 is inserted) 3b is substantially equal to the width of the OBE main body 2, A locking claw 35 is provided at the free end of the side portion. The locking claws 35 protrude inward from each other and have a shape that can be engaged with locking grooves 25 provided on both side surfaces of the vehicle-mounted device body 2. And when the front-end | tip of the onboard equipment main body 2 contact | abuts to the inner bottom face 3a of the onboard equipment holder 3, the latching claw 35 is located so that the latching claw 35 may become a position corresponding to the locking groove 25 of the onboard equipment main body 2. Each position of the locking groove 25 is set. Further, the side portion of the vehicle-mounted device holder 3 is flexible and has elasticity to return to the original state when bent.

  Therefore, when inserting the in-vehicle device body 2 into the in-vehicle device holder 3, it is inserted so as to widen the gap between the locking claws 35 on both sides, and the tip of the in-vehicle device body 2 is inserted into the inner bottom surface 3 a of the in-vehicle device holder 3. In the case of contact, the locking claw 35 of the vehicle-mounted device holder 3 is caught in the locking groove 25 of the vehicle-mounted device main body 2 (that is, locked). Thereby, the vehicle-mounted device body 2 is held by the vehicle-mounted device holder 3. Note that when the vehicle-mounted device body 2 is pulled out of the vehicle-mounted device holder 3, the locking groove 25 of the vehicle-mounted device body 2 is detached from the locking claw 35 of the vehicle-mounted device holder 3. Thus, the onboard equipment body 2 and the onboard equipment holder 3 are configured to be detachable.

(Electrical configuration of the vehicle-mounted device 2)
Next, the electrical configuration of the vehicle-mounted device body 2 will be described with reference to FIG.
As shown in FIG. 2, the vehicle-mounted device body 2 includes a wireless unit 10, a control processing unit 11, a CPU 12, a security application module (SAM) 13, a memory 14, a card interface (I / F) 16, a switch group 17, a display unit. 18, an audio output unit 19, and a power management unit 20.

  The wireless unit 10 includes a known communication circuit and antenna. And it is used for the radio | wireless communication for the automatic toll collection process performed, for example between the road devices installed in the toll booth etc. of the toll road. Further, it is also used for communication with the vehicle-mounted device holder 3.

The control processing unit 11 is for converting the reception signal received by the radio unit 10 into reception data by signal processing or converting transmission data into a transmission signal by signal processing.
The CPU 12 is configured in the same manner as a well-known arithmetic unit, performs arithmetic processing based on transmission / reception data, data read from the SAM 13, and the like, and performs initial setting processing of ETC on-board unit (charge settlement information and setup information writing processing). And toll collection processing in the ETC system.

  The SAM 13 and the memory 14 are nonvolatile memories for storing vehicle information, user information, passwords, holder identification information (holder ID), and the like. This information is, for example, an information writing holder provided in a setup store that operates a setup agency such as a car dealer or a car accessory store (the in-vehicle device holder 3 has the same configuration, and is connected to an external power source instead of a vehicle power source). Connected)) and set the in-vehicle device body 2 to write. When the vehicle-mounted device body 2 is set in the information writing holder, power is supplied to the vehicle-mounted device body 2. In this state, a setup card or the like is inserted into the card slot, and necessary information such as vehicle information, user information, password, and holder ID is read out and stored in the SAM 13 or the memory 14.

  In the present embodiment, as shown in FIG. 3, a table for storing a holder ID and vehicle information in association with each other in the memory 14 is prepared. This table can store a plurality of sets of holder IDs and vehicle information. The procedure for storing the holder ID and vehicle information in this table will be described later.

  The card I / F 16 is an interface for exchanging data with an external device, and is used when data is transmitted / received to / from a card installed in a card slot.

  The switch group 17 is used for a user to input various operation instructions and data. The display unit 18 and the audio output unit 19 are for informing the user of information such as the state of the device and the fee settlement in the ETC system.

  The power management unit 20 is for supplying power to each unit in the vehicle-mounted device body 2 when power is supplied from the outside. Specifically, it is assumed that power is supplied in a non-contact manner from a power management unit 120 of the vehicle-mounted device holder 3 to be described later. Specifically, when the power management unit 20 of the vehicle-mounted device body 2 enters the propagation range of the electromagnetic field generated by the power management unit 120 of the vehicle-mounted device holder 3, an electromotive force is generated in the coil in the power management unit 20 by electromagnetic induction. As a result of this electromotive force, the power management unit 20 supplies power to each unit in the vehicle-mounted device body 2.

  The vehicle-mounted device main body 2 includes, for example, a casing formed by molding synthetic resin or the like, and the above-described components, that is, the wireless unit 10, the control processing unit 11, the CPU 12, the SAM 13, the memory 14, and the card interface (I / F) 16 The switch group 17, the display unit 18, the audio output unit 119, and the power management unit 20 are built in and are sealed except for the card slot portion.

(Electric configuration of the vehicle-mounted device holder 3)
Next, the electrical configuration of the vehicle-mounted device holder 3 will be described with reference to FIG.
As shown in FIG. 2, the in-vehicle device holder 3 includes a wireless unit 110, a control processing unit 111, a CPU 112, a memory 114, a mounting detection unit 115, a password (PW) input unit 117, and a power management unit 120.

The wireless unit 110 includes a known communication circuit and antenna. And it is used for communication between the radio | wireless parts 10 of the onboard equipment main body 2. FIG.
The control processing unit 111 is for converting the reception signal received by the wireless unit 110 into reception data by signal processing or converting transmission data into a transmission signal by signal processing.

  The CPU 112 is configured in the same manner as a well-known arithmetic unit, performs arithmetic processing based on transmission / reception data, data read from the memory 114, and the like, and executes legitimacy determination processing, power supply / stop control processing described later, and the like. .

The memory 114 is for storing a holder ID for identifying the holder. This holder ID is stored in the memory 114 when the on-vehicle device holder 3 is manufactured.
The mounting detector 115 is mounted on the inner bottom surface of the in-vehicle device holder 3 (the inner surface with which the tip of the in-vehicle device body 2 abuts when the in-vehicle device body 2 is inserted) 3a (see FIG. 1). When the vehicle-mounted device body 2 is depressed by being depressed by the vehicle-mounted device main body 2, it is detected that the vehicle-mounted device main body 2 is mounted.

The PW input unit 117 is for a user to input a password, and is configured by, for example, a numeric keypad.
The power management unit 120 is connected to the vehicle power source 100 and can supply power to each unit in the in-vehicle device holder 3 and also supplies power to the power management unit 20 of the in-vehicle device body 2. It is configured to be able to. Whether or not power is supplied to the power management unit 20 of the vehicle-mounted device 2 is configured to be switchable by the CPU 112. Note that the power supply from the power management unit 120 of the vehicle-mounted device holder 3 to the power management unit 20 of the vehicle-mounted device main body 2 is executed in a non-contact manner. As described above, for example, when the power management unit 20 of the vehicle-mounted device body 2 enters the propagation range of the electromagnetic field generated by the power management unit 120 of the vehicle-mounted device holder 3, the coil in the power management unit 20 is caused by electromagnetic induction. Electric power is generated, and the power management unit 20 supplies power to each unit in the vehicle-mounted device main body 2 by the electromotive force.

[Operation of ETC OBE 1]
Next, the operation of the ETC vehicle-mounted device 1 of this embodiment will be described. FIG. 3 is a schematic explanatory diagram illustrating a procedure in which the holder ID and the vehicle information are stored in association with each other in the table in the memory 14 of the vehicle-mounted device body 2. FIG. 4 is a flowchart showing processing executed by the CPU 12 of the vehicle-mounted device main body 2, and FIG. 5 is a flowchart showing processing executed by the CPU 112 of the vehicle-mounted device holder 3.

Note that the processing on the vehicle-mounted device main body 2 side shown in FIG. 4 and the processing on the vehicle-mounted device holder 3 side shown in FIG. 5 are related to each other. .
In the processing on the vehicle-mounted device holder 3 side shown in FIG. 5, it is determined whether or not the vehicle-mounted device main body 2 is mounted in the first step S210. As described in the above description of the configuration, when the vehicle-mounted device body 2 is mounted on the vehicle-mounted device holder 3, the mounting detection convex portion 31 of the vehicle-mounted device holder 3 is pushed down by the vehicle-mounted device body 2 and sinks. Since the mounting detection unit 115 of the vehicle-mounted device holder 3 detects that the vehicle-mounted device main body 2 is mounted due to the sinking of the mounting detection convex portion 31, based on the detection result from the mounting detection unit 115, in S210 It is determined whether the vehicle-mounted device body 2 is attached.

  While the in-vehicle device body 2 is not attached (S210: NO), the determination process of S210 is repeatedly executed. When the in-vehicle device body 2 is attached (S210: YES), the process proceeds to S220.

  In S220, as a process for starting power supply to the vehicle-mounted device body 2, the power management unit 120 is controlled to supply power to the power management unit 120 of the vehicle-mounted device body 2. Specifically, when the power management unit 120 generates an electromagnetic field, and the power management unit 20 of the vehicle-mounted device body 2 enters the propagation range of the electromagnetic field generated by the power management unit 120, the power management unit 20 is electromagnetically induced. An electromotive force is generated in the inner coil. The power management unit 20 supplies power to each unit in the vehicle-mounted device body 2 by this electromotive force.

  When power is supplied to each part in the vehicle-mounted device main body 2 in this way, the processing on the vehicle-mounted device main body 2 side shown in FIG. 4 is started. In the first step S10 in the processing on the vehicle-mounted device main body 2 side shown in FIG. 4, a self-diagnosis is performed and the result is judged. If the diagnosis result is abnormal, the fact is notified to the user via the display unit 18 and the audio output unit 19 (S20).

  In the self-diagnosis in S10, a memory check, a peripheral IC check, and authentication (holder authentication) regarding the on-board device holder of the mounting partner are also executed. This holder authentication acquires holder ID from the onboard equipment holder 3, and performs authentication based on the holder ID. However, it is not an authentication as to whether or not the same holder ID is stored on the OBE main body 2 side, and for example, the OBE main body 2 and the OBE holder 3 are assumed to use both as a set. It is authentication to the extent that it is judged whether or not. For example, if it is assumed that only products of the same manufacturer are used, and if the OBE main unit of another manufacturer is attached to the OBE holder, it is diagnosed as abnormal, and that fact Notification is made (S20).

By the way, the authentication result based on the holder ID obtained by the self-diagnosis in S10 is transmitted to the in-vehicle device holder 3 via the wireless unit 10.
On the OBE holder 3 side, the OBE authentication shown in S230 of FIG. 5 is executed based on the authentication result based on the holder ID transmitted from the OBE main body 2 side. In the present embodiment, authentication based on the holder ID is executed in the vehicle-mounted device main body 2. However, for example, the vehicle-mounted device main body 2 and the vehicle-mounted device holder 3 may exchange IDs with each other and perform authentication in each. . For example, the OBE main body 2 acquires the holder ID from the OBE holder 3 and performs authentication, and the OBE holder 3 acquires the OBE ID “identification information unique to the OBE main body 2” from the OBE main body 2. Authentication.

  If the authentication result is abnormal (NG) in S230, the power management unit 120 is controlled to stop the power supply to the power management unit 20 of the vehicle-mounted device body 2 (S240). Specifically, when the power management unit 120 stops the generation of the electromagnetic field, the generation of electromotive force of the power management unit 20 by electromagnetic induction stops, and the power supply to each unit in the vehicle-mounted device body 2 stops. As a result, the vehicle-mounted device main body 2 becomes substantially unusable.

  The timing at which the power supply stop (S240) is executed is delayed by a predetermined time (for example, several seconds) from the start timing of the abnormality notification in the vehicle-mounted device body 2 shown in S20 of FIG. Therefore, after the abnormality notification (S20) in the vehicle-mounted device body 2 is executed for a predetermined time, the power supply is stopped and the notification itself is not made.

  On the other hand, if the in-vehicle device authentication is normal (OK), the power supply is continued (S250). In this case, since normal judgment (OK) is also made in S10 of FIG. 4, the process proceeds to S30, and the vehicle information corresponding to the holder ID acquired from the vehicle-mounted device holder 3 for self-diagnosis in S10 is stored in the memory. 14 is determined whether it exists in the table 14 (see FIG. 3).

  If the setup has not been executed, as shown in FIG. 3A, since “corresponding vehicle information” does not exist in the table, a negative determination is made in S30, and the process proceeds to S40. In S40, the user is informed via the display unit 18 and the audio output unit 19 that it has not been set up. Therefore, when the user who has recognized the notification that the setup has not been performed intends to execute the setup, the setup card is inserted into the card slot shown in FIG.

  Note that the setup is often executed at a setup store that operates a setup agency such as a car dealer or a car supply store. Therefore, when the setup is executed at such a setup store, the on-board unit holder 3 is not actually mounted on the vehicle and the power is supplied from the vehicle power supply 100, but the power is supplied from a commercial power source or the like at the setup store. The Rukoto.

  Of course, the in-vehicle device holder 3 may be actually mounted on the vehicle and executed. However, in the present embodiment, one on-vehicle device body 2 is used for the on-vehicle device holder 3 mounted on a plurality of vehicles. To be able to. Therefore, if the in-vehicle device holder 3 is actually mounted on the vehicle and the setup is executed, it is inconvenient that the user needs to bring a plurality of vehicles actually used to the setup store. Therefore, it is more convenient for the set-up to be executed without actually being mounted on the vehicle. Further, when the setup is executed at the setup store in this way, it is considered that the staff of the setup store executes the setup process, not the person who actually uses the vehicle-mounted device 1. Therefore, for example, in the case of the above-mentioned case “when the user who has recognized the notification that the setup has not been made intends to execute the setup, the setup card is inserted into the card slot shown in FIG. "Person" means the staff of the setup shop.

  If a setup card is inserted into the card slot, an affirmative determination is made in S50, and a setup process is executed in S60. In this setup process, setup information including information (vehicle information) related to the vehicle on which the vehicle-mounted device is to be mounted and the user is read from the setup card and stored in the SAM 13 or the memory 14.

  It is determined whether or not the result of the setup process in S60 is normal (S70). If normal, the process proceeds to S80. In S80, the holder ID and the vehicle information are stored as a set in a table in the memory 14. This point will be further described with reference to FIG.

FIG. 3A shows a state where no set of holder IDs and vehicle information is stored in the table in the memory 14 of the vehicle-mounted device body 2.
In the self-diagnosis in S10 of FIG. 4, as shown in FIG. 3B, the holder ID is read from the memory 114 of the vehicle-mounted device holder 3 to the temporary memory (RAM) on the vehicle-mounted device main body 2 side. And in the setup process in S60 of FIG. 4, as shown in FIG.3 (c), vehicle information is read to a temporary memory from a setup card. Then, in S80 of FIG. 4, as shown in FIG. 3D, the holder ID and the vehicle information that have been read to the temporary memory are stored in a set (that is, associated) in the table in the memory 14. The

  As a result, a set of holder ID and vehicle information is stored. By repeating such processing, a plurality of sets of holder IDs and vehicle information can be stored in the table in the memory 14. For example, when three vehicles are owned, if the vehicle information is A, B, C, and the holder IDs of the vehicle-mounted device holders fixed to the vehicles are α, β, γ, the table in the memory 14 The three sets of information of vehicle information A-holder IDα, vehicle information B-holder IDβ, and vehicle information C-holder IDγ are stored.

  Returning to the description of FIG. 4, when the holder ID and the vehicle information are stored as a set in the table in the memory 14 at S80, the setup to the user is completed via the display unit 18 and the audio output unit 19 at S90. Inform the effect.

  On the other hand, when the result of the setup process is not normal (S70: NG), the process proceeds to S100, and the user is notified of the card abnormality via the display unit 18 and the audio output unit 19.

After the processing of S90 and S100, the process returns to S30. Note that the setup card is removed after the processing of S90 and S100.
The setup was required because a negative determination was made in S30, but a positive determination was made in S30, that is, vehicle information corresponding to the holder ID acquired from the vehicle-mounted device holder 3 for self-diagnosis in S10. If it exists in the table in the memory 14 (see FIG. 3), the process proceeds to S110.

In S110, a notification is made to prompt the user to input a password via the display unit 18 and the audio output unit 19.
In the processing on the vehicle-mounted device holder 3 side in FIG. 5, when the power supply is continued in S250, a password input is waited in S260. As described above, in S110 of FIG. 4, the user is prompted to enter the password, and when the user inputs the password via the password input unit 117 (see FIG. 2) (S270: YES), the password is mounted on the vehicle. It transmits to the main body 2 and waits for the result of password verification (S280).

  In the processing on the vehicle-mounted device main body 2 side in FIG. 4, it is determined whether or not a password is received in S120. When the CPU 12 determines that the wireless unit 10 of the vehicle-mounted device body 2 has received the password transmitted from the vehicle-mounted device holder 3 side (S120: YES), password verification is performed (S130). This password verification determines whether or not the received password matches the password read from the memory 14. The password verification result is transmitted to the on-vehicle device holder 3 side.

  In the in-vehicle device body 2, if the result of the password verification in S 130 is not valid (S 140: NG), the user is notified through the display unit 18 and the audio output unit 19 that the password cannot be used (S 150). ). On the other hand, if the result of the password verification is valid (S140: OK), it is determined whether or not a card is inserted in the card slot (S160). If there is a card (S160: YES), it is authenticated whether the card is an ETC card that can be used in the in-vehicle device body 2 (S170). As a result, if the ETC card is usable in the in-vehicle device body 2 (S180: OK), the user is notified through the display unit 18 and the audio output unit 19 that the ETC is available (S190). If the card is not an available ETC card (S180: NG), the user is notified via the display unit 18 and the audio output unit 19 that the card is abnormal (S200).

After the processing of S190 and S200, the process returns to S160.
On the other hand, the in-vehicle device holder 3 side waits for the password verification result in S280, and then determines the password verification result transmitted from the in-vehicle device body 2 side (S290). If the password verification result is valid, the power supply is continued (S300). If the verification result is not valid, the power management unit 120 is controlled to stop the power supply to the power management unit 20 of the vehicle-mounted device body 2. (S310). Specifically, when the power management unit 120 stops the generation of the electromagnetic field, the generation of electromotive force of the power management unit 20 by electromagnetic induction stops, and the power supply to each unit in the vehicle-mounted device body 2 stops. As a result, the vehicle-mounted device main body 2 becomes substantially unusable.

  When the power supply is continued in S300, it is determined whether or not the vehicle-mounted device body 2 is removed. If the vehicle-mounted device body 2 is removed (S320: YES), the power management unit 120 is controlled. The power supply to the power management unit 20 of the vehicle-mounted device body 2 is stopped (S330).

[Effects of ETC OBE 1]
According to the ETC vehicle-mounted device 1 of the present embodiment, a plurality of sets of holder IDs and vehicle information can be stored in the table in the memory 14 of the vehicle-mounted device body 2. For example, when the user owns three vehicles, the vehicle information is A, B, and C, and the holder IDs of the in-vehicle device holders fixed to the vehicles are α, β, and γ. In this case, the table in the memory 14 may store three sets of information: vehicle information A-holder IDα, vehicle information B-holder IDβ, and vehicle information C-holder IDγ. For a user who owns the plurality of vehicles, if the vehicle-mounted device holders 3 corresponding to the number of vehicles are fixed to the respective vehicles, only one vehicle-mounted device body 2 is required. The vehicle-mounted device body 2 can be rotated.

  Moreover, in the ETC onboard equipment 1 of this embodiment, when it has not set up, it will alert | report via the display part 18 or the audio | voice output part 19 (refer S40 of FIG. 4). Therefore, it is possible to prompt the user to execute the setup process.

  In the ETC vehicle-mounted device 1 of the present embodiment, when the vehicle-mounted device body 2 is mounted on the vehicle-mounted device holder 3, power supply is started from the vehicle-mounted device holder 3 to the vehicle-mounted device body 2 (see S220 in FIG. 5). The container body 2 becomes operable. However, even if power supply is once started in this way, authentication based on identification information such as a holder ID is performed, and if it is determined not to be valid (S230: NG), power supply to the vehicle-mounted device body 2 is stopped. (S240), unauthorized use can be prevented.

  And when the power supply to the onboard equipment main body 2 is stopped in this way and the onboard equipment main body 2 becomes unusable, the fact is notified on the onboard equipment main body 2 (S20 in FIG. 4B). The above notification is not necessary when used by a person who has been illegally acquired due to theft or the like, but even if it is a legitimate user, the in-vehicle device body 2 of another person is mistakenly attached to the in-vehicle device holder 3 of the own vehicle. It is also assumed that Therefore, if the user is informed that it is worn by mistake, the user can recognize that fact.

  If only the in-vehicle device body 2 is stolen, it can be dealt with by the validity judgment by the authentication such as the holder ID as described above, but if the in-vehicle device holder 3 and the in-vehicle device body 2 are stolen as a set, Unauthorized use cannot be avoided only by checking the holder ID. Therefore, password verification is also weighted. If it is determined that the password verification is not valid (S290: NG in FIG. 5), the power supply to the vehicle-mounted device body 2 is stopped (S310), so that the vehicle-mounted device holder 3 and the vehicle-mounted device body 2 are set. Even if it is stolen, it cannot be used without knowing the password, and unauthorized use can be prevented more reliably.

  Also in this case, the in-vehicle device body 2 notifies that the in-vehicle device body 2 cannot be used because the power supply to the in-vehicle device body 2 is stopped (S150). As in the case of authentication using the above-described holder ID or the like, it is assumed that even a legitimate user erroneously attaches the vehicle-mounted device body 2 of another person to the vehicle-mounted device holder 3 of the own vehicle. Therefore, if it is notified that the password authentication is not valid even though the password that the user thinks is correct is entered, the user mistakenly attaches the vehicle-mounted device body 2 of another person, for example, to the vehicle-mounted device of the own vehicle. It can be noticed that the holder 3 has been mounted.

However, since the vehicle-mounted device body 2 is carried and carried, it is preferable to provide it on the vehicle-mounted device holder 3 side from the viewpoint that it is better not to provide parts.

  (2) When the vehicle-mounted device body 2 is normally attached to the vehicle-mounted device holder 3, the user may be able to recognize that fact. Specifically, a simple notification that the LED is turned on when the power is supplied to the vehicle-mounted device body 2 side is sufficient. The LED in this case may be provided in the vehicle-mounted device body 2 or may be provided in the vehicle-mounted device holder 3.

Moreover, the notification which displays on the display part 18 of an onboard equipment main body by the character of "normal mounting | wearing" may be sufficient, and you may alert | report with the audio | voice from the audio | voice output part 19. FIG.
