Description

  The present invention relates to the technical field of keyless entry systems. In particular, the present invention relates to a technical field of a keyless entry system that uses a mobile communication terminal as a keyless entry terminal.

  With the rapid spread of mobile phones, calls using mobile phones while driving automobiles (hereinafter referred to as vehicles) have become a major problem. Calls during driving generally prevent the driver from concentrating on driving operations, and are therefore a major factor in inducing traffic accidents.

  Therefore, in recent years, even when there is an incoming call in an operation mode that is changed (shifted) in response to a predetermined user operation, the incoming call history information is recorded in the own device without ringing the ringtone. There has been proposed a mobile phone capable of the above. In such an operation mode, a guidance is sent to the other party (sender) who has received the call that the called party is driving. According to such a mobile phone, ringing of the ringtone is restricted, so that it is possible to prevent the driver from responding to (answering) the incoming call during the driving operation.

  Here, as a prior art existing prior to the present application, for example, there are the following patent documents.

  That is, Patent Document 1 proposes an electronic security system that can lock and unlock a door lock mechanism of a vehicle using an IC card possessed by a passenger. In this IC card, fingerprint information of the passenger is registered in advance. In the system, the device on the vehicle side performs authentication using the fingerprint information read from the IC card and the fingerprint read from the occupant's finger.

  Further, Patent Document 2 discloses that in a system constituted by a mobile phone capable of short-range wireless communication and a vehicle-side control device, when the engine speed of the vehicle exceeds a predetermined value, the passenger has Techniques have been proposed for restricting outgoing calls from mobile phones (allowing incoming calls).

  Further, in Patent Document 3, a call signal sent from a portable terminal (mobile phone) in response to pressing of a call button is received by an in-vehicle device, and authenticated by a caller ID included in the call signal. According to the result, an antitheft system capable of releasing the door lock of the vehicle has been proposed.

  Patent Document 4 discloses an anti-theft technique in which authentication is performed between a portable information terminal connected via a transceivable interface and an in-vehicle device, and the steering lock, mission lock, and door lock of the vehicle can be released. A system has been proposed.

  Patent Document 5 proposes a vehicle security system that uses an IC card held by a passenger to release the door lock mechanism of the vehicle. In the IC card, unique information such as the vehicle body number of the vehicle and the telephone number of the passenger is registered in advance.

JP 2001-342760 A (paragraph number 0032, FIG. 4) JP 2003-102058 (paragraph number 0018, FIG. 7) Japanese Patent Laying-Open No. 2003-120097 (paragraph numbers 0009 and 0010, FIG. 2) Japanese Patent Laying-Open No. 2003-327055 (paragraph number 0025, FIG. 2) JP 09-164914 A (paragraph number 0014, FIG. 2)

  By the way, the transition to the operation mode in which ringing of ringtones is restricted requires an operation by a user (driver) who intends to use the operation mode. For this reason, the user may forget the operation or consider the operation to be bothersome and start driving without performing the operation. In this case, a user who is a driver may make a call during a driving operation without using the special functions.

  Therefore, in order to solve such a problem, it is only necessary that the transition to the operation mode can be automatically performed. As a device configuration that automatically shifts to the above operation mode while riding a vehicle, a user's movement by the vehicle (for example, detection of movement at a predetermined speed or more) is detected by a GPS (global positioning system) mounted on a mobile phone. A method of detection is conceivable.

  However, in the case where each passenger (user) who is traveling carries a mobile phone having the same function with an operation mode for restricting the movement detection and ringtone by the GPS, the individual passengers are individually Mobile phones perform the same operation. For this reason, although passengers other than the driver can talk without any danger even while the vehicle is traveling, all the passengers cannot answer the incoming call while the vehicle is traveling, which is not convenient. In addition, a mobile phone having such a function has a problem that, for example, in a driving environment such as waiting for a signal or in a traffic jam, it cannot be determined whether the vehicle is driving or not.

  Therefore, an object of the present invention is to accurately switch the notification operation by the mobile communication terminal depending on whether or not the user performs a driving operation of the vehicle.

  In order to achieve the above object, a keyless entry system according to the present invention has the following configuration.

That is, a keyless entry system that locks and unlocks a door lock mechanism of a vehicle by performing communication by a short-range wireless communication means between a mobile communication terminal and an in-vehicle device mounted on the vehicle,
In response to the mobile communication terminal and the in-vehicle device performing the communication in a state where the door lock mechanism is locked, the door lock mechanism is unlocked, and then the communication is performed. Until the door lock mechanism is locked, a notification operation (notification by voice, vibration, light emission, etc.) to the user among the operations of the mobile communication terminal is prohibited.

  Further, for example, it is preferable to prohibit at least incoming call notification while the notification operation is prohibited. In this case, the incoming call to the mobile communication terminal itself may be prohibited.

In a preferred embodiment, the short-range wireless communication means includes
An RF-ID (Radio Frequency ID) tag provided in the portable communication terminal and a reader / writer of the RF-ID tag provided in the in-vehicle device.

  In the above case, the antenna of the reader / writer is preferably provided in the driver's door of the vehicle or in the vicinity thereof.

In addition, another detection that achieves the same purpose is a mobile communication terminal that locks and unlocks a door lock mechanism of the vehicle by performing short-range wireless communication with an on-vehicle device mounted on the vehicle,
Short-range wireless communication means for communicating with the in-vehicle device;
In the state where the door lock mechanism is locked, the vehicle-mounted device and the short-range wireless communication means communicate with each other to unlock the door lock mechanism, and then the communication is performed to lock the door lock mechanism. Control means for prohibiting the notification operation to the user among the operations of the mobile communication terminal,
It is characterized by providing.

  This object is also achieved by a method corresponding to the above-described keyless entry system.

  The object is also achieved by a computer program for realizing a portable communication terminal constituting the keyless entry system having the above-described configurations by a computer, and a computer-readable storage medium storing the computer program. Achieved.

  According to the present invention, the notification operation by the mobile communication terminal can be accurately switched according to whether or not the user is operating the vehicle.

  Hereinafter, in the keyless entry system according to the present invention, a mobile phone (1), which is a typical mobile communication terminal, and an in-vehicle device (3) mounted on a vehicle (vehicle) are examples of short-range wireless communication. A system configuration for exchanging information using an RF-ID (Radio Frequency ID) tag (wireless IC tag) will be described as an example.

  The keyless entry system according to this embodiment includes a mobile phone 1 and an in-vehicle device 3 mounted on a vehicle 2. Next, after describing the configuration of each of the mobile phone 1 (FIG. 1) and the in-vehicle device 3 (FIG. 2), the usage mode of the keyless entry system according to the present embodiment will be described with reference to FIGS. .

<Mobile phone 1>
FIG. 1 is a block configuration diagram illustrating a mobile phone 1 constituting the keyless entry system according to the present embodiment.

  In the present embodiment, the mobile phone 1 is roughly divided into an antenna 201, a wireless transmission / reception circuit 202, a control circuit 203, an operation device (including a pointing device) 207, a display device 208, a microphone 209, a speaker 210, a vibrator 211, and A wireless ID tag 212 is provided.

  The control circuit 203 includes a CPU (Central Processing Unit) 200, an operation memory 204, a holding memory 205, an ID memory 206, and hardware (not shown). In the control circuit 203, the CPU 200 controls the operation of each unit of the mobile phone 1 by executing a program group read from the holding memory 205.

  Specifically, the CPU 200 of the control circuit 203 performs an incoming call notification by detecting the call number of the own device from the signal demodulated by the wireless transmission / reception circuit 202. Further, the CPU 200 of the control circuit 203 realizes voice communication using the microphone 209 and the speaker 210, data communication such as a mail transmission / reception function, a server connection function, and the like by processing voice signals and digital data signals.

  Further, the CPU 200 of the control circuit 203 follows instructions input by the user via the operation device 207 when executing the program group read to the operation memory 204.

  The display device 208 includes a display 208A such as a liquid crystal display. The display device 208 displays, on the display 208A, various input contents that are linked to the user's operation on the operation device 207, various messages and symbols that notify the user of the operation state of the terminal.

  The ID memory 206 holds the calling number (calling number) of the own device. In the control circuit 203, the CPU 200 uses the calling number (calling number) read from the ID memory 206 to collate data corresponding to a predetermined position of the demodulated signal.

  A random access memory (RAM) 204 is used as a work when the CPU 200 operates.

  The holding memory 205 is a non-volatile memory (Flash Memory or the like), and holds, for example, an operation program of the CPU 200, various parameters, information indicating the operation state of the door lock mechanism 306A acquired via the wireless ID tag 212, and the like. .

  Note that a part of the operation memory 204, the holding memory 205, and the ID memory 206 may be realized by dividing an area in the physically same device.

  The antenna 201 transmits and receives a phase-modulated radio wave and has the same function as an antenna of a known wireless communication terminal.

  The radio transmission / reception circuit 202 demodulates radio waves received from the antenna 201 and performs phase modulation on the digital signal output from the control circuit 203. The wireless transmission / reception circuit 202 has a function similar to that of a known wireless transmission / reception circuit of a wireless communication terminal.

  The vibrator 211 notifies the user of an incoming call by driving an actuator (not shown) according to an instruction from the control circuit 203.

  A wireless ID (RF-ID) tag 212 is a wireless IC chip that performs wireless communication with the reader / writer 302 (reader / writer antenna 303) on the vehicle 2 side. In the present embodiment, the wireless ID tag 212 is used for instructing the operation of the door lock mechanism 306A and acquiring information indicating the operation state of the mechanism through the wireless communication (details will be described later).

  Here, since the wireless communication itself performed between the wireless ID tag 212 and the reader / writer 302 can employ a general configuration at present, for example, using a non-contact power transmission technique, Detailed description in the embodiment is omitted.

  The user's voice is input to the microphone 209. The speaker 210 outputs a predetermined ring tone, call voice or the like to the user.

  It should be noted that a general technique can be employed for operations such as data transmission / reception processing and voice processing performed by the mobile phone 100 with an external device in the above-described device configuration. For this reason, the detailed description in this embodiment is abbreviate | omitted.

<In-vehicle device 3>
Next, the device configuration on the vehicle side will be described. FIG. 2 is a block diagram illustrating a configuration on the vehicle 2 side that configures the keyless entry system according to the present embodiment.

  In the figure, a vehicle 2 includes an in-vehicle device 3 that performs wireless communication with a mobile phone 1 and performs door lock control of the vehicle 2. The in-vehicle device 3 roughly includes an ECU (Electronic Control Unit) 301, a reader / writer 302, a power supply unit 304, a display unit 305, and a door lock unit 306.

  The ECU 301 manages the wireless communication with the mobile phone 1 and the door lock control of the vehicle 2 by executing an operation control program in the CPU 301A.

  The reader / writer 302 reads information from the wireless ID tag 212 provided in the mobile phone 1 and writes information to the tag in accordance with an instruction from the ECU 301.

  The power supply unit 304 controls power supply to the reader / writer 302, the door lock unit 306, and the like in accordance with an instruction from the ECU 301.

  The display unit 305 performs various displays for the occupant, for example, the operating state of the door lock mechanism 306A in accordance with an instruction from the ECU 301.

  The door lock unit 306 controls the operation state of the door lock mechanism 306A that locks (locks) and unlocks (unlocks) the door provided in the vehicle 2 in accordance with an instruction from the ECU 301.

  The antenna 303 performs wireless communication (including non-contact power transmission as necessary) with the wireless ID tag 212 on the mobile phone 1 side in order to realize reading and writing operations by the reader / writer 302. Antenna.

  FIG. 3 is a diagram illustrating a usage mode of the keyless entry system according to the present embodiment. In this embodiment, the reader / writer antenna 303 is provided around the doorknob of the driver's seat door 4 of the vehicle 2 as an example, as shown in FIG. FIG. 4 is a flowchart for explaining a usage mode of the keyless entry system according to the present embodiment.

(Unlock)
First, when getting on the vehicle 2, the user holding the mobile phone 1 performs an action of holding the mobile phone 1 close to the antenna 303 (the mobile phone 1 may be in direct contact with the position of the antenna 303. The same applies hereinafter). Perform (step S1).

  Then, triggered by such an action, the wireless ID tag 212 provided on the mobile phone 1 and the antenna 303 (reader / writer 302) are separated from each other within a predetermined distance range in which wireless communication is possible. Wireless communication between the ID tag 212 and the reader / writer 302 is started. That is, the reader / writer 302 stores in advance the authentication code of the mobile phone 1 that forms a pair with the in-vehicle device 3 so as to constitute the keyless entry system. The reader / writer 302 collates the stored authentication code with the authentication code read from the wireless ID tag 212 located within the predetermined distance range (step S2). After performing the authentication, the in-vehicle device 3 unlocks the door lock mechanism 306A by controlling the door lock unit 306 when the door lock mechanism 306A is locked (step S3). Thereby, the user can perform unlocking of the vehicle 2 and subsequent boarding without using an ignition key or the like. That is, in the present embodiment, the mobile phone 1 functions as a keyless entry terminal. The communication procedure from the locked state to the unlocking will be described later.

  In addition, the mobile phone 1 changes the operation mode of the mobile phone 1 to “drive mode” in response to wireless communication for unlocking being performed between the wireless ID tag 212 and the reader / writer 302. Let The “drive mode” is a mode that prohibits (regulates) the notification operation to the user among the operation modes of the mobile phone 1.

  Here, the notification operation is performed in order to notify (inform) the user of the occurrence of an event such as an incoming call, reception of an e-mail, or other packet reception for an application function being executed. And this alerting | reporting operation | movement is performed in at least any one aspect among the audio | voice output in the mobile telephone 1, a vibration, and light emission. In such “drive mode”, although the notification operation itself to the user performed in at least one of the modes is prohibited, the user's driving operation is not hindered if the notification is not performed.

  Therefore, in the present embodiment, the mobile phone 1 performs operations that do not accompany the user by voice or the like (recording of incoming histories, message message storage processing, e-mail reception processing, etc.) itself. Further, when the mobile phone 1 records the incoming call history while prohibiting the notification operation, the mobile phone 1 displays a message or a predetermined symbol on the display 208A so that the user (driver) can recognize this later. Is displayed.

  In addition, the mobile phone 1 notifies a message to the effect that the user of the mobile phone 1 is driving the vehicle to a caller who has received an incoming call while prohibiting the notification operation. In this case, the operation of notifying the message to the caller is a general procedure performed by the mobile phone 1 alone or by the mobile phone 1 and the infrastructure side (that is, an external device such as a base station or a control station). It can be realized by collaborating as appropriate. For this reason, detailed description for notifying such a message on a source device (telephone or the like) is omitted.

  Further, in the “drive mode”, not only a notification operation but also a call operation from the mobile phone 1 (call transmission, e-mail transmission, etc.) is prohibited in order to prevent dangerous actions such as a call while driving. You can also take the idea. However, in this embodiment, only the notification operation is prohibited in order to enable emergency contact when an emergency occurs while driving the vehicle.

(locking)
Thereafter, when the user gets off the vehicle 2 at the destination, for example, after closing the door, the user again performs an action of holding the mobile phone 1 close to the antenna 303 (step S1). Then, triggered by such an action, the wireless ID tag 212 provided on the mobile phone 1 and the antenna 303 (reader / writer 302) are separated from each other within a predetermined distance range in which wireless communication is possible. Wireless communication between the ID tag 212 and the reader / writer 302 is started. At this time, after performing authentication (step S2) as in the case of the unlocking described above, the in-vehicle device 3 locks the door lock mechanism 306A by controlling the door lock unit 306 (step S3). Thereby, the user can lock the vehicle 2 using the mobile phone 1 that functions as a keyless entry terminal without using an ignition key or the like. The communication procedure from the unlocked state until the locking is performed will be described later.

  In addition, the mobile phone 1 changes the operation mode of the mobile phone 1 to the “drive mode” until then when the wireless communication for locking is performed between the wireless ID tag 212 and the reader / writer 302. To another operation mode in which a notification operation to the user is performed.

  Therefore, the user can easily lock and unlock the door lock mechanism 306 </ b> A using the mobile phone 1. Furthermore, the mobile phone 1 transitions to the “drive mode” over a period in which the door lock mechanism 306A is in the unlocked state (that is, while the vehicle is in the vehicle 2). For this reason, the user who is an occupant is not prevented from concentrating on the driving operation by the notification operation by the mobile phone 1.

  In this embodiment, as shown in FIG. 3, the reader / writer antenna 303 is provided around the doorknob of the driver's seat door 4. For this reason, in principle, it is the mobile phone 1 possessed by the user who is the driver of the vehicle 2 that can cause the series of locking and unlocking operations described above. Therefore, even if a passenger who gets on and off using a door other than the driver's seat of the vehicle 2 is carrying the mobile phone 1, the notification operation is not restricted while the vehicle 2 is in the vehicle, and the normal operation is performed as usual. Can be used. However, the installation place of the reader / writer antenna 303 for enjoying this convenience is not limited to the vicinity of the door knob of the driver's door 4. For example, the reader / writer antenna 303 may be provided on the rim of the driver's seat door 4 or on the roof edge of the vehicle 2 near the door.

  Thus, the mobile phone 1 and the vehicle-mounted device 3 described above constitute a keyless entry system (smart keyless entry system) in the present embodiment.

<Control processing>
Next, control processing executed in the mobile phone 1 and the in-vehicle device 3 to realize the above-described series of operations will be described with reference to FIGS. 5 and 6.

  FIG. 5 is a flowchart showing a control process performed by the ECU 301 of the in-vehicle device 3. The flowchart shown in the figure represents the processing procedure of the software program executed by the CPU 301A in the ECU 301 in the in-vehicle device 3 shown in FIG.

  FIG. 6 is a flowchart showing a control process performed by the control circuit 203 of the mobile phone 1. The flowchart shown in the figure represents the processing procedure of the software program executed by the CPU 200 in the control circuit 203 in the mobile phone 1 shown in FIG.

  That is, the wireless ID tag 212 and the reader / writer 302 are wirelessly connected when the distance between the wireless ID tag 212 provided on the mobile phone 1 and the antenna 303 is within a predetermined distance range in which wireless communication is possible. Start communication. At this time, the CPU 200 of the mobile phone 1 transmits the authentication code of its own terminal to the in-vehicle device side (step S201 in FIG. 6). In the ECU 301 of the in-vehicle device 3, the CPU 301 </ b> A uses the received authentication code to authenticate whether the mobile phone is a valid terminal paired with the own device (step S <b> 101 in FIG. 5).

  When the authentication is successful in step S101, the CPU 301A uses the reader / writer 302 to store information indicating the current operation state of the door lock mechanism 306A stored in a memory (not shown) in the ECU 301 or the like. Is written to the wireless ID tag 212 (step S102 in FIG. 5).

  In mobile phone 1, CPU 200 determines whether or not the information written in wireless ID tag 212 indicates the locked state of door lock mechanism 306A (step S202 in FIG. 6). If the determination at step S202 is YES (locked state), the CPU 200 transmits an unlock instruction signal to the in-vehicle device 2 side to unlock the door lock mechanism 306A (step S203 in FIG. 6). On the other hand, if the determination is NO in step S202 (unlocked state), the CPU 200 transmits a locking instruction signal to the in-vehicle device 2 side to lock the door lock mechanism 306A (step S206 in FIG. 6). The sent unlocking instruction signal or locking instruction signal is received by the reader / writer antenna 303.

  Next, when transmitting the unlock instruction signal in step S203, the CPU 200 of the mobile phone 1 determines whether or not the current operation mode of the terminal itself is “drive mode” (step S204 in FIG. 6). When it is determined in step S204 that the operation mode is an operation mode other than “drive mode” (in the case of NO determination), the CPU 200 shifts the operation mode of its own terminal to “drive mode” ( Step S205 in FIG. 6). Thereby, the mobile phone 1 prohibits a notification operation such as ringing of a ringtone until the next operation mode is changed.

  On the other hand, when transmitting the lock instruction signal in step S206, the CPU 200 of the mobile phone 1 determines whether the current operation mode of the terminal itself is “drive mode” (step S207 in FIG. 6). When it is determined in step S207 that the operation mode is “drive mode” (in the case of YES determination), the CPU 200 shifts the operation mode of the own terminal to an operation mode other than “drive mode” ( Step S208 in FIG. As a result, the mobile phone 1 performs a notification operation such as ringing of a ringing tone until the next transition to the “drive mode”.

  Even in the other operation modes, when a so-called manner mode is selected, the output of a ringtone or the like is appropriately regulated.

  By the way, in the ECU 301 of the vehicle-mounted device 3, the CPU 301A receives an unlocking instruction signal or a locking instruction signal in accordance with the processing of the above steps S203 to S206 in the mobile phone 1 (steps S103 and S105 in FIG. 5). .

  If the CPU 301A determines that the unlock instruction signal has been received in step S103 (in the case of YES determination), the CPU 301A instructs the door lock unit 306 to unlock the door lock mechanism 306A (step S104 in FIG. 5). . On the other hand, when CPU 301A determines that the lock instruction signal has been received in step S105 (in the case of YES determination), it instructs the door lock unit 306 to lock the door lock mechanism 306A (step S106 in FIG. 5).

  Then, after the instructions in steps S103 to S106, the CPU 301A stores information indicating the current operation state of the door lock mechanism 306A in a memory (not shown) in the ECU 301 (step S107 in FIG. 5). The information stored in this step is information referred to in step S102 described above.

  The operation mode setting process in step S205 (step S208) described above is performed according to the unlocking instruction signal (locking instruction signal) sent in step S203 (step S206). 306) may be executed after confirming that the operation has actually been completed. More specifically, the completion of the operation is confirmed by the cellular phone 1 by a procedure such as writing the answer back information indicating the completion of the operation from the reader / writer 302 to the wireless ID tag 212 or transmitting it by e-mail. It ’s fine.

  In the above-described embodiment, the door lock mechanism 306A is unlocked while the user of the mobile phone 1 is driving the vehicle 2 as a driver. For this reason, when the infant is carrying, the situation which wants to lock is also assumed. Therefore, in such a case, a driver or another passenger may perform a door lock operation manually in the vehicle interior. Even if such an operation is performed, in the system configuration described above, the in-vehicle device 3 and the mobile phone 1 in the transition to the “drive mode” are independent. Therefore, the notification operation by the mobile phone 1 can be continued because the prohibited state can be continued.

  According to the present embodiment described above, the notification operation by the mobile phone 1 can be accurately switched according to whether or not the user (driver) is driving the vehicle 2.

  That is, when the door lock mechanism 306A is unlocked, in this embodiment, it can be determined that the user of the mobile phone 1 is driving the vehicle after getting on the vehicle 2. Therefore, in the present embodiment, the ringing tone control and the like are accurately started when the mobile phone 1 automatically shifts to the “drive mode” without forcing the user to perform troublesome operations. Therefore, attention is paid to the ringing tone that is started during the driving operation, the driver's attention to the driving operation is reduced, and the incoming call is answered during the driving operation. The occurrence of dangerous situations can be prevented in advance.

  When the door lock mechanism 306A is locked, it can be determined that the user of the mobile phone 1 has got off the vehicle 2 in this embodiment. Therefore, in the present embodiment, by automatically shifting the mobile phone 1 to an operation mode other than the “drive mode”, the ringing tone restriction or the like is surely released without forcing the user to perform troublesome operations. Therefore, the situation where the user does not notice the incoming call can be prevented by continuing the “drive mode” even after getting off.

<Modification of Embodiment>
In the above-described embodiment, the case where the present invention is applied to a mobile phone which is a typical mobile communication terminal has been described. However, the application range of the present invention is not limited to this, and can be applied to an information processing apparatus such as a PDA (Personal Digital Assistance) having a short-range wireless communication function.

  In the above-described embodiment, the case where the in-vehicle device 3 and the mobile phone 1 communicate by RF-ID is described as an example of the short-range wireless communication method. However, the present invention is not limited to the RF-ID, and a short-range wireless communication method such as infrared communication or Bluetooth can be employed.

  In the above-described embodiment, the notification operation to the user by the mobile phone 1 is prohibited in the “drive mode”. However, the present invention is not limited to such a configuration, and a configuration in which operations such as incoming calls to the mobile phone 1 and reception of e-mails are prohibited may be adopted. In this case, the control circuit 203 of the mobile phone 1 and the infrastructure side of the mobile phone 1 (that is, an external device such as a base station or a control station) cooperate appropriately in switching processing for allowing or prohibiting operations such as incoming calls. It can be realized by doing so.

  In the above-described embodiment, the keyless entry function using the mobile phone 1 is described as an example of a type that does not require the user to perform key operations (so-called alternate type). However, the present invention is not limited to such a device configuration. More specifically, an apparatus configuration in which a lock instruction signal or an unlock instruction signal is sent in response to a key operation of the operation device 207 of the mobile phone 1 may be employed.

  Further, in the above-described embodiment, a configuration in which the notification operation to the user by each operation mode of voice, vibration, and light emission (using a lamp (not shown) of the mobile phone 1) is prohibited during the “drive mode” is taken as an example. explained. However, the present invention is not limited to such a device configuration. More specifically, an apparatus configuration that prohibits at least one of these operation modes may be employed. However, in order not to prevent the driver from concentrating on the driving operation, it is desirable to prohibit notification by all these operation modes.

  In addition, when the user holds (places) the mobile phone 1 (wireless ID tag 212) in the vicinity of the antenna 303 (reader / writer 302), so-called chattering occurs, such as locking immediately after unlocking. Is also expected. Therefore, in order to prevent such an inappropriate operation, an appropriate detection threshold (time margin) may be provided in each of the above-described processing steps that involve determination.

  The present invention described by taking the above-described embodiments as examples can realize the functions of the flowcharts (FIGS. 5 and 6) referred to in the description for the above-described mobile communication terminal 1 and the ECU 301 of the in-vehicle device 3. After the computer program is supplied, the computer program is read out and executed by the CPU (200, 301A) of the apparatus.
