FIG. 1 is a conceptual diagram showing an embodiment of a communication system 1 for a vehicle to which the present invention is applied. The communication system 1 is configured to include a vehicle 10, a portable device 20, and a portable terminal 30.
For example, the vehicle 10 and the portable device 20 perform wireless communication using radio waves in an LF (Low Frequency) band or an UHF (Ultra High Frequency) band, and transmit and receive various commands and information. Since the portable device 20 functions as a key of the vehicle 10, for example, a unique communication method with excellent security is adopted as a communication method between the vehicle 10 and the portable device 20.
The portable device 20 and the portable terminal 30 perform non-contact wireless communication with a maximum communication distance of about several centimeters, and transmit and receive various commands and information. As a communication method between the portable device 20 and the portable terminal 30, for example, NFC (Near Field Communication) used in communication standards such as Felica (registered trademark) and MIFARE (registered trademark) used in RFID communication and the like. Common communication standards such as alias wireless communication and infrared communication (IrDA Data, etc.) are used. The portable device 20 and the portable terminal 30 are often used by being held by one user, and contactless wireless communication with a small maximum communication distance is sufficient and preferable.
For example, in addition to NFC, infrared communication, Bluetooth (registered trademark), the mobile terminal 30 and the vehicle 10 use a general communication standard such as an Internet line (Wi-Fi, etc.) or a telephone line (W-CDMA, etc.). Thus, direct wireless communication may be performed to selectively transmit and receive various commands and information. Since the portable terminal 30 and the vehicle 10 may be used at a long distance apart from the portable device 20 and the vehicle 10, a telephone line or a popular Internet line is used in addition to the short-range wireless communication. Thereby, for example, when parking in an underground parking lot or the like, even if the UHF communication of the vehicle 10 from the portable device 20 is disconnected, the portable terminal 30 communicates directly with the vehicle 10 through a telephone line or an Internet line. Can do.
The portable device 20 has a function as a unique key for the vehicle 10, and a unique identification code of the portable device 20 is registered in the vehicle 10. For example, the portable device 20 has a function as a normal physical key for the vehicle 10 or an entry key function in the smart entry system. That is, the portable device 20 performs locking and unlocking of the door of the vehicle 10 when a switch or the like near the door of the vehicle 10 is operated, or when the vehicle 10 and the portable device 20 become communicable or when the user The vehicle information is acquired by a trigger such as when it is operated.
Further, the portable device 20 has a function of relaying communication between the vehicle 10 and the portable terminal 30. That is, the portable device 20 receives a command, information, or the like transmitted from the vehicle 10 and transfers the command, information, or the like to the portable terminal 30, or conversely, receives a command, information, or the like transmitted from the portable terminal 30. 10 can be transferred.
The portable terminal 30 can perform non-contact wireless communication with the portable device 20 and can execute a predetermined application program (hereinafter referred to as a vehicle program) for acquiring and displaying vehicle information and operating the vehicle 10. If it is a portable apparatus provided with the display part for displaying vehicle information, it will not be limited to a specific kind. For example, the portable terminal 30 includes a mobile phone, a smartphone, a personal digital assistant (PDA), a portable music player, a portable game machine, and the like. The vehicle information includes the locked state of each door, the amount of fuel, the remaining amount of the battery, the elapsed charging time, the lighting state of the lamp, the temperature state of the vehicle interior, the temperature around the vehicle, the vehicle position information, and the like.
FIG. 2 is a block diagram illustrating a functional configuration of the communication system 1 according to the present embodiment. First, an outline of processing between the vehicle 10 and the portable device 20 will be described with reference to FIG. The communication system 1 includes a portable device 20 capable of wireless communication with the vehicle 10 and a portable terminal 30 capable of non-contact wireless communication with the portable device 20. When a user performs a command operation for obtaining vehicle information or instructing vehicle control in the portable device 20 or the portable terminal 30, the command content is transmitted from the vehicle communication unit 24 of the portable device 20 to the vehicle communication unit 11 of the vehicle 10. Sent. In the vehicle 10, based on the transmitted command content, the vehicle control unit 12 controls the corresponding on-vehicle device, or the vehicle information acquisition unit 13 acquires the corresponding vehicle information. Then, the vehicle 10 transmits the control result contents and the acquired vehicle information from the vehicle communication unit 11 to the vehicle communication unit 24 of the portable device 20. Then, the portable device 20 stores the control result contents and vehicle information in the storage unit 25.
After the portable device 20 acquires vehicle information from the vehicle 10 in this way, when the portable device 20 and the portable terminal 30 are within a distance where non-contact wireless communication can be used, the portable device 20 and the portable terminal communication unit Non-contact wireless communication with 31 is performed. When non-contact wireless communication is started between the portable device 20 and the portable terminal communication unit 31, non-contact wireless communication is established between the two according to a predetermined protocol if there is no particular problem. In NFC communication (non-contact wireless communication), a protocol from the start to establishment between the two will be described later.
The portable device 20 and the portable terminal 30 are both carried and carried by the user. For example, it is assumed that the user carries the portable device 20 and the portable terminal 30 in the same bag or pocket. However, the portable device 20 and the portable terminal communication unit 31 are, for example, in the user's bag or pocket. If the contactless wireless communication continues to be within a usable distance, the contactless wireless communication is continued. Therefore, the communication system 1 is configured to perform predetermined conditions even after the contactless wireless communication is started between the portable device 20 and the mobile terminal communication unit 31 that are within a distance where the contactless wireless communication can be used. If is established, contactless wireless communication is prohibited and contactless wireless communication is not resumed unless a predetermined instruction is received.
By doing so, it is possible to prevent unnecessary communication between the portable device 20 and the portable terminal 30 regardless of the user's intention. In addition, since the portable terminal 30 normally turns on an LED lamp for screen display to display on the screen of the portable terminal 30 when the non-contact wireless communication is started, The screen of the portable terminal 30 continues to be in the ON state by the start of communication. However, the communication system 1 can prevent the screen from being turned on even in such a case. As a result, the communication system 1 can reduce unnecessary power consumption.
More specifically, the portable terminal 30 of the communication system 1 includes a first transmitter 32 that transmits a first signal to the portable device 20, and a first receiver 33 that receives a second signal from the portable device 20. Have Moreover, the portable device 20 controls the generation of the second signal with respect to the second receiver 22 that receives the first signal transmitted by the first transmitter 32 and the first signal that is received by the second receiver 22. It has the control part 23 and the 2nd transmission part 21 which transmits the 2nd signal which the control part 23 produced | generated to the 1st receiving part 33 of the portable terminal 30. FIG.
And the portable terminal 30 may prohibit transmission of the 1st signal from the 1st transmission part 32, when predetermined conditions are satisfied. That is, if the mobile terminal 30 does not transmit a first signal that is a call to the mobile device 20, contactless wireless communication between the mobile terminal 30 and the mobile device 20 is not started. According to this, unnecessary power consumption can be reduced by the portable terminal 30 detecting a predetermined condition and prohibiting communication.
Alternatively, the portable device 20 may prohibit the transmission of the second signal from the second transmission unit 21 when a predetermined condition is satisfied. That is, if the portable device 20 does not transmit a second signal that is a response to the call from the portable terminal 30, contactless wireless communication between the portable terminal 30 and the portable device 20 will not be established. According to this, unnecessary power consumption can be reduced by the portable device 20 detecting a predetermined condition and prohibiting communication.
Moreover, the control part 23 of the portable device 20 transmits the transmission prohibition request signal of the first signal together with the second signal when the predetermined condition is satisfied, and the portable terminal 30 receives the transmission prohibition request signal. In this case, the transmission of the first signal may be prohibited. According to this, unnecessary power consumption can be reduced by the portable device 20 detecting a predetermined condition and the portable terminal 30 prohibiting communication.
Note that the predetermined condition is that when the non-contact wireless communication is established a predetermined number of times within a predetermined time, or when the non-contact wireless communication is continued for a predetermined time or more, the vehicle program is displayed on the screen of the portable terminal 30. The case where there is no user operation for a predetermined time or more. Details will be described later.
For example, when the battery of the vehicle 10 is charged at the power supply station, the user wants to check the state of charge of the battery and operates the mobile terminal 30 to acquire vehicle information indicating how much the battery is charged. . When the user places the mobile terminal 30 next to the mobile device 20 or places the mobile terminal 30 on the mobile device 20, the mobile terminal 30 establishes contactless wireless communication with the mobile device 20. And the portable terminal 30 starts the program for vehicles which is a predetermined | prescribed application, and displays the screen of the application on the portable terminal display part 36. FIG. In this way, the application screen is automatically displayed simply by bringing the portable device 20 and the portable terminal 30 close to each other, so that the user can immediately perform a desired operation or confirm desired vehicle information.
Next, when the user performs a command operation for acquiring information on the state of charge of the battery from the vehicle 10 by the application using the portable terminal operation reception unit 35, the information can be acquired via the portable device 20. The mobile terminal control unit 34 performs control between the mobile terminal communication unit 30, the mobile terminal operation reception unit 35, and the mobile terminal display unit 36 related to this application.
Then, after confirming the charge state of the acquired battery, the user left it next to the portable device 20. Then, the portable terminal 30 continues to establish non-contact wireless communication with the portable device 20, but when the non-contact wireless communication continues to be established for a predetermined time or more, the portable terminal 30 or the portable device 20 Prohibit communication.
Processing for prohibiting contactless wireless communication in this case will be described with reference to FIGS. FIG. 3 is a flowchart for explaining from the start to establishment of general NFC communication (non-contact wireless communication) between the portable device 20 and the portable terminal 30. FIG. 4 is a flowchart of the portable terminal for prohibiting NFC communication when NFC communication between the portable device 20 and the portable terminal 30 continues to be established for a predetermined time or longer in the communication system of the present embodiment. .
First, the establishment of NFC communication will be described with reference to FIG. In S800, the mobile terminal 30 including the mobile terminal communication unit 31 having the function of an NFC reader / writer periodically generates an electromagnetic wave corresponding to a first signal for calling the mobile device 20 from the mobile terminal communication unit 31. The mobile device 20 inquires whether or not the portable device 20 exists in the communicable range. Although the frequency of the electromagnetic wave used in the present embodiment is 13.56 Mhz, it goes without saying that the present invention is not limited to this.
If the portable device 20 is in a position to receive the electromagnetic wave, in S802, the portable device 20 generates an electromotive force by the electromagnetic wave. In S804, the portable device 20 activates the CPU of the portable device 20 with the generated electromotive force. When the CPU is activated, the portable device 20 transmits its own unique identification code to the portable terminal 30 and responds to an inquiry from the portable terminal 30 in S806. Note that when the transmission of the second signal is prohibited, the control unit 23 of the portable device 20 determines that the predetermined condition is satisfied even when the CPU is activated, and does not perform the step of S806. No second signal is sent as a response to the call.
In S808, the mobile terminal 30 that has received the response transmits an inquiry signal to the mobile device 20 using the received identification code. In step S <b> 810, the portable device 20 that has received the inquiry signal transmits a response signal to the portable terminal 30. Then, in S812, the mobile terminal 30 that has received the response signal transmits an authentication code to the mobile device 20.
In S <b> 814, the portable device 20 that has received the authentication code returns a cryptographic operation code to the portable terminal 30 and recognizes that NFC communication with the portable terminal 30 has been established. In step S <b> 816, the mobile terminal 30 that has received the cryptographic operation code recognizes that NFC communication with the mobile device 20 has been established. Therefore, a command signal is transmitted to the portable device 20.
Accordingly, the establishment of NFC communication means that both recognize that NFC communication has been established through the steps from S800 to S816. Note that S808 and S812 may be performed simultaneously.
Next, with reference to FIG. 4, a process in which the portable terminal 30 prohibits contactless wireless communication when contactless wireless communication continues to be established for a predetermined time or longer will be described. When the user places the portable terminal 30 next to the portable device 20, the steps S800 to S816 described above are performed between the portable device 30 and the portable device 20 in S202. In S204, the process proceeds to S816, and if the mobile terminal 30 recognizes that the NFC communication has been established, the process proceeds to S206, and if it is not recognized that the establishment has been established, nothing is performed.
When the NFC communication is established, in S206, the mobile terminal 30 activates a vehicle program that is a predetermined application. In step S208, the portable terminal 30 displays the application screen on the portable terminal display unit. When information on the state of charge of the battery can be acquired, the state is displayed. Thereafter, the user leaves the portable terminal 30 for a while. Then, in S210, the mobile terminal 30 checks whether or not NFC communication is continuing, and if the user continues to place the mobile terminal 30 next to without operating the mobile terminal 30, the NFC communication is disconnected. Since it continues without it, it progresses to S212.
In S212, for example, if it is less than 5 minutes after NFC communication is established, it is continuously checked whether NFC communication is continuing. However, if NFC communication has never been disconnected for 5 minutes or more, NFC communication is prohibited in S214. Specifically, in the case of the mobile terminal 30, the mobile terminal 30 does not generate an electromagnetic wave first in NFC communication. Then, S800 and subsequent steps are not executed. Further, when the portable device 20 prohibits, the portable device 20 prohibits the NFC interrupt.
If NFC communication is prohibited, the timer is cleared in S216. Note that when checking whether or not the NFC communication is continued in S210, the timer is cleared in S216 even when the user moves from the side of the portable device 20 and the NFC communication is disconnected. If NFC communication is not successful in S204, nothing is performed.
Next, with reference to FIG. 5, a process in which the portable terminal 30 prohibits non-contact wireless communication when the non-contact wireless communication is established a predetermined number of times or more within a predetermined time will be described. For example, the NFC communication is not continued because the user is holding and moving the portable terminal 30 placed next to the portable device 20, but the communication is repeatedly established or disconnected. . In addition, the description which overlapped with FIG. 4 is abbreviate | omitted suitably. S100 to S108 are the same as S200 to S208.
In S110, the timer is counted, and if NFC communication is once established within 10 minutes, for example, the number of NFC communication established in S118, that is, the number of steps S800 to S816 is counted up. Note that the timer can be counted by interrupt processing. In S120, if the count-up is less than 5, for example, S104 to S118 are repeated. On the other hand, when the count-up becomes 5 times or more, NFC communication is prohibited.
Note that NFC communication may be prohibited by determining that a predetermined condition is satisfied when the mobile terminal 30 receives the second signal a predetermined number of times from the mobile device 20 within a predetermined time. According to this, the portable terminal 30 can be prohibited after confirming that the portable device is surely in a state where non-contact communication should be prohibited. On the portable device 20 side, for example, when the portable device 20 receives a predetermined number of times of the first signal from the portable terminal 30 within a predetermined time, it is determined that a predetermined condition is satisfied, and NFC communication is prohibited. May be. According to this, after confirming that the portable terminal 30 is in a state where the non-contact communication should be prohibited reliably, the portable device 20 can be prohibited.
In addition, the portable terminal 30 prohibits NFC communication and turns off the screen display in S124. According to this, unnecessary power consumption can be reduced by automatically turning off the screen together with communication prohibition. In the mobile terminal 30 such as a mobile phone or a smartphone, the screen display is one of the factors that consumes the most battery power. Therefore, non-contact communication is prohibited and the screen is held in the OFF state, so that power consumption in the mobile terminal 30 is not unnecessarily consumed.
In addition, after the NFC communication is prohibited, the mobile terminal 30 displays a notification that the NFC communication is prohibited when the user performs an operation for displaying a screen and an operation method for performing a predetermined instruction. May be displayed on the screen. According to this, the user can check the communication state, and can guide an operation that can be performed next.
Next, referring to FIG. 6, after the NFC communication between the portable device 20 and the portable terminal 30 is established, the vehicle program displays an application on the screen of the portable terminal, and there has been no user operation for a predetermined time or more. In this case, a process in the portable terminal 30 that prohibits NFC communication will be described. For example, the user is holding the portable terminal 30 placed next to the portable device 20 in his / her hand and repeatedly repeating the operation.
In S302, when the user activates an application that is a vehicle program, in S304, the application displays on the screen. If the user performs an operation on the application in S306, the application executes processing based on the operation content of the user in S308. In S310, the timer is cleared, and the process proceeds to S312.
If the user performs an operation in S306, the process proceeds directly to S312. In S312, it is checked whether or not the timer has elapsed, for example, 5 minutes. If the time has not elapsed, S306 to S310 are repeated. On the other hand, if, for example, 5 minutes or more have elapsed since the last operation, NFC communication is prohibited in S314. In S316, since there is no user operation for a predetermined time or longer, the screen of the portable terminal 30 is turned off to enter the sleep state. Note that the next time the user operates and displays the screen, a display indicating that NFC communication is stopped may be performed.
Next, with reference to FIG. 7, processing when resuming NFC communication after NFC communication between the portable device 20 and the portable terminal 30 is prohibited will be described. Note that (A) shows processing in a portable terminal, and (B) shows processing in a portable device. In order to resume NFC communication, it is necessary to give a predetermined instruction. For example, when the user has left the portable terminal 30 next to the portable device 20 for a long time, NFC communication between the portable terminal 30 and the portable device 20 is prohibited.
The portable terminal 30 detects a touch on the screen or a button operation of the user in S402. In S403, the NFC communication is resumed, that is, the electromagnetic wave transmission prohibition is canceled, and the state in which S800 can be performed is restored.
In S502, the user's operation to the operation receiving unit or the like is detected in S502, and in S504, NFC communication is resumed, that is, the prohibition of NFC interrupt processing (response signal transmission) is canceled.
As described above, the predetermined instruction for resuming the NFC communication may be a user's predetermined operation on the mobile terminal 30. Thus, by resuming communication by a user's predetermined operation, it is possible to prevent communication from resuming regardless of the user's intention. Note that the predetermined instruction may be an instruction by incoming call to the mobile terminal 30. According to this, it is possible to give an instruction from a distance.
In addition, when the above-mentioned predetermined operation is performed, a notification that NFC wireless communication is prohibited is displayed on the screen of the mobile terminal 30, and NFC wireless communication is resumed by a different predetermined operation following the previous operation. May be. According to this, it is possible to prevent communication from being resumed regardless of the user's intention by resuming communication by a predetermined operation after the user confirms the communication state. For example, if the user confirms the notification that NFC wireless communication is prohibited in the previous operation and then continues to swipe a predetermined operation, for example, the screen of the mobile terminal 30 in a specific direction, the NFC wireless communication Can be resumed, and if it is not desired to be resumed, it is possible to entrust the user to the resume by performing another operation.
On the other hand, the portable terminal 30 may resume the transmission of the first signal from the first transmission unit 21 when it receives a predetermined instruction when any operation is performed by the user. According to this, non-contact wireless communication can be restarted quickly by a user operation.
