Description

  The present invention relates to a communication device system.

  In recent years, improvements in user convenience have been demanded in vehicles such as four-wheeled vehicles. For this reason, the vehicle authenticates the ID code of the portable device through wireless communication with the portable device (electronic key), and locks and unlocks the vehicle door and drives the engine and motor on the condition that the authentication is established. It is equipped with an electronic key system that allows the source to start. In this electronic key system, for example, as disclosed in Patent Document 1, a smart communication system that automatically performs verification when the electronic key approaches the vehicle, or wireless communication that remotely operates the vehicle by operating a button on the electronic key. There are systems.

  The electronic key performs wireless communication with the vehicle when power is supplied from the battery. For this reason, the voltage of a battery falls with progress of use years of an electronic key. That is, the voltage may not be able to perform wireless communication with the vehicle. In preparation for such a battery running out of the electronic key, a mechanical key is accommodated in the electronic key, and the door lock and unlocking when the battery runs out is handled by using the mechanical key. Furthermore, a transponder is built in the electronic key, and engine start when the battery runs out is handled by bringing the electronic key closer to the coil antenna in the vehicle and establishing ID verification by the transponder.

JP 2001-31333 A

  However, even when the electronic key is equipped with a mechanical key or a transponder to take measures against running out of the battery, it is rare that the electronic key runs out of battery. For this reason, when the battery actually runs out, it can be dealt with by using a mechanical key or transponder, but the user can actually operate the vehicle even if he has an electronic key. There was a current situation where we faced a situation where we couldn't be confused by facing a situation where we couldn't. Therefore, measures are taken such as displaying a mark indicating that the transponder is used on a vehicle meter or the like.

  On the other hand, automobiles that are global products are exported domestically, while those manufactured overseas are imported into the country. That is, a certain vehicle type is used in a plurality of countries. Nevertheless, automobile laws differ from country to country where vehicles are used. For this reason, the technology for notifying that the transponder is to be used when the battery of the electronic key has run out must also comply with the automobile laws in each country of use. For example, when notifying that the transponder is used by blinking a mark provided on the meter, the number of blinks may differ depending on the country of use. In such a case, it is necessary to prepare a plurality of types of control means for controlling blinking of the mark, select one corresponding to the country of use from the plurality of types of control means, and mount the selected one on the vehicle. However, in a series of steps until the control means is mounted on the vehicle, there is a risk of erroneous selection of one corresponding to the country of use from among a plurality of types of control means. In addition, preparing a plurality of types of control means in a single vehicle type has a large burden on the side of manufacturing the control means.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide a communication device system in which a burden on a manufacturing side and, in turn, a burden in a mounting process is small.

  In order to solve the above-mentioned problem, the invention according to claim 1 is directed to a case where the first communication device performs verification through transmission / reception of a radio signal performed between the second communication device and the verification is established.

  According to this configuration, the storage means can store the country-specific notification information corresponding to each of the countries where the first and second communication devices are used. Each country-of-use notification information corresponds to a country-of-use code. For example, the first communication device, when the determining means determines that it is necessary to notify the guidance information regarding the operation of a specific device, from the storage means the notification information for each country of use corresponding to the country of use code input from the outside in advance. Read and inform about this. Thereby, even when there are a plurality of countries in which the first and second communication devices are used, by changing the country of use input from the outside, using the notification information corresponding to the country used, Information on the operation of a specific device can be notified. Therefore, even if there are many countries where the first and second communication devices are used, only one kind of first and second communication devices are manufactured. For this reason, the burden on the manufacturing side of the first and second communication devices is small. Furthermore, the burden on the mounting process of the device mounting the first and second communication devices is small.

  According to a second aspect of the present invention, in the communication device system according to the first aspect, the notification means includes a speaker, and the notification information for each country of use passes through the speaker. The gist is to include the warning content in each language used in the country in which the communication device is used or the country-specific notification voice information for notification of the guidance information.

  According to this configuration, the warning content or the guidance information is reported in the language used in the country where the first and second communication devices are used, so that a user who is not familiar with the use of the first and second communication devices can Even when a specific device is activated, the unaccustomed user can easily recognize the warning content or the guidance information.

  According to a third aspect of the present invention, in the communication device system according to the first or second aspect, the informing means includes a speaker, and the informing information by country of use is the first and second communication through the speaker. The gist of the present invention is that the warning content or the notification sound information for each country for notification of the guidance information is included in the notification sound defined in the country of use of the machine.

  According to this configuration, since the notification sound is specified in the country of use, the user of the first and second communication devices can easily recognize the warning content or the guidance information. Moreover, when applied to Claim 2, the user of the 1st and 2nd communication apparatus can recognize warning content or guidance information more correctly.

The block diagram which shows schematic structure of an electronic key system.

Hereinafter, an embodiment in which a communication system according to the present invention is embodied in an electronic key system between a vehicle and an electronic key will be described with reference to FIG.
As shown in FIG. 1, the electronic key system 1 includes an electronic key 10 possessed by a driver of the vehicle 2 and an in-vehicle device 20 disposed in the vehicle 2. The vehicle 2 executes or permits door locking / unlocking and engine starting on the condition that mutual wireless communication (smart communication) performed with the electronic key 10 is established.

<Electronic key>
The electronic key 10 has a wireless communication function, and controls various in-vehicle devices through mutual wireless communication with the in-vehicle device 20. The electronic key 10 includes an electronic key control unit 11 configured by a computer unit including a CPU, a ROM, a RAM, and the like, and an LF reception unit that is electrically connected to the electronic key control unit 11 and receives an LF band request signal. 14 and a UHF transmitter 13 for transmitting a response signal in the UHF band. When receiving the LF band request signal transmitted from the in-vehicle device 20, the LF receiving unit 14 demodulates the request signal into a pulse signal, and outputs the demodulated demodulated signal to the electronic key control unit 11. The electronic key 10 includes a battery 18 that supplies power to each part of the electronic key 10 such as the electronic key control unit 11. The battery 18 is a primary battery that can be replaced. The electronic key control unit 11 is driven by consuming electric power supplied from the battery 18. The electronic key 10 includes a mechanical key 19 for locking and unlocking the door of the vehicle 2.

  The electronic key control unit 11 is provided with a non-volatile memory 11 a that stores an ID code for mutual authentication with the in-vehicle device 20. The ID code stored in the memory 11a is unique to the electronic key 10. When receiving the request signal, the electronic key control unit 11 generates a response signal including the ID code stored in the memory 11a. Then, the generated response signal is output to the UHF transmission unit 13. The UHF transmission unit 13 modulates the input response signal into the UHF band, and transmits the modulated response signal to the in-vehicle device 20.

  The electronic key 10 also includes a transponder communication circuit 17 that is electrically connected to the electronic key control unit 11. The transponder communication circuit 17 includes a coil and an IC chip. When the transponder communication circuit 17 receives the driving radio wave, an induced power is generated in its coil. The transponder communication circuit 17 consumes the induced power generated in the coil, generates a transponder response signal including the ID code stored in the memory 11a of the electronic key control unit 11, and transmits the generated trapon response signal.

<In-vehicle device>
As shown in FIG. 1, the in-vehicle device 20 includes a first ECU 21 that controls various in-vehicle devices, and an LF transmission unit 24 that is electrically connected to the first ECU 21 and transmits a request signal in the LF band. And a UHF receiver 23 for receiving a response signal in the UHF band. The in-vehicle device 20 includes an immobilizer communication device 25 that is electrically connected to the first ECU 21. The immobilizer communication device 25 is provided, for example, in the vicinity of the engine switch 33, and locally transmits a driving radio wave in the vicinity of the engine switch 33. The drive radio wave is transmitted by inputting a command signal indicating that the drive radio wave is transmitted to the immobilizer communication device 25. Further, when receiving the transponder response signal, the immobilizer communication device 25 sends the transponder response signal to the first ECU 21. The first ECU 21 also functions as a determination unit that determines that a drive radio wave is transmitted to the immobilizer communication device 25.

  The first ECU 21 is electrically connected to a door handle sensor 32 that is provided on the door handle and detects whether or not the user touches the door handle, and a door lock device 34 that locks and unlocks the vehicle door. ing. Further, the first ECU 21 is electrically connected to an engine switch 33 that is operated when the engine is started, and an engine control device 35 that performs start control of the engine of the vehicle 2. The door handle sensor 32 outputs an electrical signal indicating that it has been touched, and the engine switch 33 outputs an electrical signal indicating that it has been operated to the first ECU 21. In addition, a speaker 36 is electrically connected to the first ECU 21. The speaker 36 converts a later-described notification audio signal (electric signal) from the first ECU 21 into a physical vibration, and transmits the vibration to the interior space (air). When the vibration of the air is transmitted to the user's ear, the user recognizes the vibration as a so-called sound (notification sound).

  The first ECU 21 is electrically connected to a courtesy switch 37 that detects opening and closing of the vehicle door. The first ECU 21 detects opening / closing of the vehicle door through the courtesy switch 37. The vehicle door is provided with a key hole (not shown) mechanically connected to the door lock device 34, and the key hole corresponds to the mechanical key 19. The door lock device 34 locks and unlocks the vehicle door by inserting the mechanical key 19 into the keyhole and rotating the mechanical key 19. When the door lock device 34 locks and unlocks the vehicle door with the mechanical key 19, the door lock device 34 sends an electric signal indicating that to the first ECU 21. When the first ECU 21 satisfies both the input of an electrical signal indicating that the vehicle door is locked and unlocked by the mechanical key 19 and the input of opening and closing of the vehicle door through the courtesy switch 37 Then, it is determined that the driving radio wave is transmitted to the immobilizer communication device 25, and a command signal indicating that the driving radio wave is transmitted is transmitted.

  The first ECU 21 is provided with a nonvolatile memory 21a that stores various types of information. The memory 21 a stores an ID code common to the electronic key 10 corresponding to the memory 21 a and the country-specific voice information 22 of the vehicle 2. The country-by-country notification sound is a sound for notifying that the engine is started using the transponder communication circuit 17 in the language for each country in which the vehicle 2 is used. Here, it is assumed that the electronic key 10 is brought close to the engine switch 33 and a sound indicating that the engine switch 33 is operated while a brake pedal (not shown) is depressed. In the present embodiment, it is assumed that the vehicle 2 is used in five countries. Accordingly, the memory 21 a stores five types of audio signals A to E as the country-specific audio information 22. The five types of audio signals A to E are stored in the memory 21a in a state associated with the country codes A to E. The country of use code is unique to the country of use where the vehicle 2 is used.

  When the first ECU 21 receives the response signal, the first ECU 21 performs verification (external vehicle verification) between the ID code included in the response signal and the ID code stored in the memory 21a. When the vehicle outside verification is established, the first ECU 21 activates the door handle sensor 32.

  In a state where the engine of the vehicle 2 is stopped, the first ECU 21 transmits a request signal toward the set communication area in the vehicle compartment through the LF transmission unit 24. The first ECU 21 starts the engine through the engine control device 35 when the engine switch 33 is operated in a state in which collation (in-vehicle collation) triggered by this request signal is established.

  When the first ECU 21 detects that the mechanical door 19 is unlocked using the mechanical key 19 and the vehicle door is opened and closed through the courtesy switch 37, the first ECU 21 determines that a driving radio wave is transmitted from the immobilizer communication device 25. . Then, a command signal indicating that the driving radio wave is transmitted is output. Thereby, the immobilizer communication device 25 transmits a driving radio wave in the vicinity of the engine switch 33. At this time, the first ECU 21 notifies the voice indicating that the engine switch 33 is operated by bringing the electronic key 10 close to the engine switch 33 through the speaker 36. When the first ECU 21 receives the transponder response signal through the immobilizer communication device 25, the first ECU 21 compares the ID code included in the transponder response signal with the ID code stored in the memory 21a (trapon verification). Then, when the engine switch 33 is operated in a state where this trapon collation is established, the engine is started through the engine control device 35.

  The first ECU 21 is connected to the second ECU 41 via an in-vehicle LAN. The second ECU 41 performs display control of various indicators provided on the meter panel of the vehicle 2 or the vehicle speed. The second ECU 41 is electrically connected to a rotation sensor (not shown) that measures the number of rotations of a wheel (not shown) per unit time. The rotation sensor periodically outputs the measured number of rotations of the wheel per unit time to the second ECU 41 as rotation number information.

  The second ECU 41 is provided with a non-volatile memory 41a that stores various information for obtaining a vehicle speed to be displayed on a meter (not shown). The memory 41a includes a tire circumference (not shown), a calculation formula for obtaining a vehicle speed (vehicle speed before correction) from the circumference and rotation speed information, and a display unit for the country in which the vehicle 2 is used. And a country-specific correction formula 42 which is a calculation formula for correcting the vehicle speed to the displayed vehicle speed (corrected vehicle speed). Here, the memory 41a stores five types of correction formulas A to E as the country-specific correction formulas 42. Note that the five types of correction formulas A to E are stored in the memory 41a in a state associated with the country codes A to E.

  The second ECU 41 is connected to the service tool 50 through the in-vehicle LAN before the vehicle 2 is shipped. The service tool 50 inputs the country of use code of the vehicle 2 to the second ECU 41. Here, it is assumed that the country of use code A is input to the second ECU 41 by the service tool 50. Then, the second ECU 41 compares the input country code A with the five types of country codes A to E stored in advance in the memory 41a. Through the comparison, the second ECU 41 calculates the display vehicle speed using the correction formula A corresponding to the matching country code A.

  When the second ECU 41 obtains the rotation speed information from the rotation sensor, the second ECU 41 assigns the rotation speed information and the tire circumference stored in the memory 41a to the calculation formula also stored in the memory 41a to obtain the vehicle speed before correction. calculate. And the display vehicle speed corresponding to the display unit of the country of use of the vehicle 2 is calculated by substituting the calculated vehicle speed before correction into the correction formula A stored in the memory 41a. Then, the second ECU 41 displays the calculated display vehicle speed on a meter (not shown). Note that CAN communication is performed between the second ECU 41 and the first ECU 21 via the in-vehicle LAN, and exchange of the country of use of the vehicle 2 is performed. The first ECU 21 receives the country of use code from the second ECU 41 each time the door lock device 34 is actuated.

  In a state where the engine of the vehicle 2 is stopped, the first ECU 21 periodically generates a request signal for requesting the electronic key 10 to transmit a response signal, and the generated request signal is transmitted from the LF transmission unit 24 to the vehicle. A request signal is transmitted toward the communication area set outside. When receiving a response signal to the previous request signal from the electronic key 10, the UHF receiving unit 23 demodulates this to a pulse signal, and outputs the demodulated demodulated signal to the first ECU 21.

<Notice of starting engine using transponder>
When the battery 18 of the electronic key 10 has not run out, the user often uses smart communication (external vehicle verification) to lock and unlock the vehicle door. This is because when the vehicle door is locked and unlocked, the user does not have to take out the electronic key 10 from the pocket or the back. Accordingly, when the vehicle door is unlocked using smart communication (external vehicle collation), the battery 18 is not out of battery, so the electronic key 10 of the user who has entered the vehicle 2 and the first ECU 21 Smart communication (in-vehicle verification) can be performed between the two. The first ECU 21 permits the start of the engine if in-vehicle collation with the electronic key 10 is established.

  When the battery 18 of the electronic key 10 is dead, the user cannot lock and unlock the vehicle door using smart communication (external vehicle verification). For this reason, when the user gets into the vehicle 2, the user unlocks the vehicle door using the mechanical key 19. Of course, when the battery 18 is dead, the first ECU 21 cannot perform in-vehicle collation with the electronic key 10.

  When the mechanical key 19 is used and the vehicle door is unlocked, a signal indicating that is sent to the first ECU 21. Accordingly, the first ECU 21 recognizes that the mechanical key 19 has been used and the vehicle door has been unlocked. When the first ECU 21 detects that the vehicle door has been opened and closed through the courtesy switch 37, the first ECU 21 sends a command signal indicating that the driving radio wave is transmitted to the immobilizer communication device 25. When receiving the command signal, the immobilizer communication device 25 transmits a driving radio wave in the vicinity of the engine switch 33. At this time, the first ECU 21 notifies the speaker 36 that the engine is started using the transponder communication circuit 17. Specifically, the first ECU 21 performs CAN communication with the second ECU 41 and receives the country of use code. Then, the first ECU 21 reads the audio signal (here, A) corresponding to the received country code (here, A) from the memory 21a, converts the read signal into an electric signal, and converts the converted electric signal. The signal is output to the speaker 36. The speaker 36 converts an electric signal corresponding to the country of use code A into a physical vibration and transmits the vibration to the interior space of the vehicle. Here, a sound (language) indicating that the electronic switch 10 is brought close to the engine switch 33 and the engine switch 33 is operated (operation guidance) while depressing a brake pedal (not shown) is transmitted to the vehicle interior space. When the vibration of the air is transmitted to the user's ear, the user recognizes the vibration as sound (language). The user first brings the electronic key 10 close to the engine switch 33 by relying on voice. When the electronic key 10 is brought close to the engine switch 33, the transponder communication circuit 17 receives the driving radio wave. Thereby, the transponder communication circuit 17 obtains an induced power. The transponder communication circuit 17 consumes the induced power, generates a transponder response signal including the ID code stored in the memory 11a of the electronic key control unit 11, and transmits the generated transponder response signal. The transponder response signal is received by the immobilizer communication device 25, and the received transponder response signal is sent to the first ECU 21. The first ECU 21 performs collation (trapone collation) between the ID code included in the transponder response signal and the ID code stored in the memory 21a. And if this trapon collation is materialized, 1st ECU21 will permit starting of an engine.

  Relying on the voice, the user who brings the electronic key 10 close to the engine switch 33 then operates the engine switch 33 while stepping on the brake pedal. As a result, the engine is started if trapon verification is established. Thus, even a user who is not accustomed to using the vehicle 2 can start the engine using the transponder communication circuit 17.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) The memory 21a of the first ECU 21 includes the country-specific audio information 22 for notifying that the engine is started using the transponder communication circuit 17 from the speaker 36 in the language for each country in which the vehicle 2 is used. And stored in association with a country of use code specific to the country of use of the vehicle 2. The first ECU 21 is connected to the second ECU 41 via an in-vehicle LAN, and receives the country of use code from the second ECU 41 by CAN communication. Note that the country of use code is input to the second ECU 41 in advance by the service tool 50.

  The first ECU 21 uses the country-specific voice information 22 corresponding to the country-of-use code received from the second ECU 41 when the mechanical key 19 is used to unlock the vehicle door and the vehicle door is opened and closed. It reads from the memory 21 a and outputs the sound based on the read country-specific sound information 22 to the speaker 36. This sound reaches the user's ear, and the user can recognize that the electronic key 10 is brought close to the engine switch 33 and the engine switch 33 is operated while the brake pedal is depressed. Then, the user can start the engine by using the voice to bring the electronic key 10 close to the engine switch 33 and operating the engine switch 33 while stepping on the brake pedal. For this reason, even a user who is unfamiliar with the use of the vehicle 2 can start the engine using the transponder communication circuit 17.

  (2) The use country-specific voice information 22 read from the memory 21a by the first ECU 21 can be changed only by changing the use country code input from the service tool 50 to the second ECU 41. That is, only by inputting the country of use code, the electronic key 10 is brought close to the engine switch 33 by voice corresponding to the language of the country of use of the vehicle 2, and notification is made that the engine switch 33 is operated while the brake pedal is depressed. Can do. For this reason, even when there are many countries where the vehicle 2 is used, only one kind of first ECU 21 is manufactured. For this reason, the burden on the manufacturing side of the first ECU 21 is small. As a result, in the assembly process in which various parts and devices are assembled to the vehicle 2, there is only one type of first ECU 21, so the electronic key 10 is placed near the engine switch 33 with a voice that does not correspond to the country of use of the vehicle 2. The first ECU 21 for notifying that the engine switch 33 is operated while approaching the brake pedal is not assembled.

In addition, you may change the said embodiment as follows.
In the above embodiment, the country-specific audio information 22 output from the speaker 36 is heard by the user as a language (word), but it may be a simple sound instead of a language. That is, the memory 21a stores five types of simple sound signals associated with each of the country-of-use codes A to E instead of the five types of audio signals A to E as the country-of-use audio information 22. If comprised in this way, the simple sound which shows that it is necessary to start an engine using the transponder communication circuit 17 corresponding to the use country of the vehicle 2 will be output from the speaker 36. FIG. Thus, the user can recognize that it is necessary to start the engine using the transponder communication circuit 17 with a simple sound corresponding to the country of use. A simple sound and a voice (language) may be combined. In this way, the user can recognize more easily than either one of simple sound and voice.

  -Although the alerting | reporting of the said embodiment was based on hearing, it may be based on vision. For example, the electronic switch 10 is brought close to the knob of the engine switch 33, and the language indicating that the switch 33 is operated while stepping on the brake pedal is displayed. In this case, display information for each country of use is stored in the memory 21a instead of the voice information 22 for each country of use. Even in such a configuration, it is possible to notify that the electronic key 10 is brought close to the engine switch 33 and the engine switch 33 is operated while the brake pedal is depressed. The indication on the knob of the engine switch 33 and the sound (language), the indication on the knob of the engine switch 33 and the simple sound, or the indication on the knob of the engine switch 33 and the sound (language). And simple sounds may be combined. In this way, the user can easily recognize that it is necessary to move the electronic key 10 closer to the engine switch 33 and operate the engine switch 33 than when only the indication on the knob of the engine switch 33 is displayed. be able to. Further, it may be notified that the electronic key 10 is brought close to the engine switch 33 by providing a light on the knob of the electronic key 10 and the engine switch 33 and blinking in the same color.

  In the above embodiment, the first ECU 21 uses the transponder communication circuit 17 from the speaker 36 to notify that it is necessary to start the engine, but other notifications may be made. For example, the electronic key 10 may be taken out while the engine is running, or the vehicle door may be locked in a state where the electronic key 10 has been left in the vehicle. Even when configured in this manner, the same effects as those of the above-described embodiment can be obtained.

  In the above embodiment, the first ECU 21 is connected to the second ECU 41 via the in-vehicle LAN, but may be connected to another ECU. For example, when the vehicle 2 includes a sliding door, it may be connected to a body-type ECU that controls the operation of the sliding door. Even when configured in this manner, the same effects as those of the above-described embodiment can be obtained. In this case, the speaker 36 may be connected to a body-type ECU. Further, a memory that stores the voice information 22 for each country of use may be provided in the body ECU, and a voice signal that is notified by the body ECU may be selected.

  In the above embodiment, the speaker 36 that is a notification unit is provided in the vehicle 2, but may be provided in the electronic key 10. In this case, the country-specific voice information 22 is stored in the memory 11 a of the electronic key 10. Then, when the first ECU 21 transmits a command signal to the immobilizer communication device 25, the first ECU 21 transmits a radio signal including the country of use code to the electronic key 10. If comprised in this way, the electronic key control part 11 which received the radio signal containing a use country code will output the audio | voice signal corresponding to the use country code received from the memory 11a to a speaker. Therefore, even in such a configuration, the user can recognize through the voice to start the engine using the transponder communication circuit 17.

  In the above embodiment, the country code used by the service tool 50 is input from the second ECU 41, but may be the first ECU 21. Even in this case, the same effect as that of the above embodiment can be obtained.

  -In above-mentioned embodiment, although control of locking / unlocking in a vehicle door was performed by 1st ECU21, you may perform it by ECUs other than this. For example, it may be performed by a body ECU that controls automatic opening / closing of the vehicle door, a second ECU in the above-described embodiment that controls a meter that displays vehicle speed, and the like. That is, the door lock device 34 may be connected to an ECU other than the first ECU 21. Similarly, the door handle sensor 32, the engine switch 33, the engine control device 35, the speaker 36, and the courtesy switch 37 may be connected to an ECU other than the first ECU 21.
