Description

  The present invention relates to an electronic key system that performs ID verification using an ID signal transmitted wirelessly from an electronic key.

  2. Description of the Related Art Conventionally, a vehicle is equipped with an electronic key system that performs ID verification by transmitting an ID code wirelessly from an electronic key to the vehicle. In this electronic key system, a technique using near field communication such as NFC (see Patent Document 1) has been devised. In this case, when the outside verification is established by holding the electronic key over the reader / writer installed for verification outside the vehicle, door locking / unlocking is permitted or executed. Further, when the in-vehicle collation is established by holding the electronic key over a reader / writer installed for in-vehicle collation, engine start is permitted.

  By the way, in this type of electronic key system, reader / writers must be installed for the vehicle exterior and the interior of the vehicle, respectively. In order to reduce the number of reader / writers, for example, one reader / writer is disposed outside and inside the vehicle. There is a need to share. In this case, for example, when the electronic key located outside the vehicle and the vehicle outside verification are established, it is considered that the vehicle interior verification is also established for a certain period of time to enable the engine start operation.

JP 2009-147423 A

  However, if the in-vehicle collation is established for a certain period of time due to the establishment of the outside vehicle collation, for example, a third party aiming at theft of the vehicle will approach the vehicle in anticipation of the establishment of the outside vehicle vehicle, just push the vehicle away from the authorized user, Get on and run away. That is, even if the authorized user does not take the authorized electronic key from the authorized user, the possibility of the vehicle being stolen by the act of simply removing the user after the outside verification is established cannot be denied. Therefore, there has been a demand for a technology that can secure the security against vehicle theft while keeping the number of reader / writers small.

  An object of the present invention is to provide an electronic key system that can keep the number of communication masters mounted on a vehicle small and can secure security against vehicle theft.

  In order to solve the above problems, in the present invention, when the vehicle communication master receives the ID signal transmitted by the electronic key located outside the vehicle and the ID verification is established by the ID signal, the operation of the target device for the vehicle external verification is performed. Is an electronic key system that permits or executes outside verification as well as permits or executes the operation of the target device for in-vehicle verification, and includes the vehicle and the communication facility as a separate system from the ID verification. A communication means provided on the electronic key; a detection means for detecting an operation to be performed when restricting use of the target device for in-vehicle verification; and when the detection means detects the restriction operation, Transmission control means for transmitting a restriction request signal from the electronic key to the vehicle, and when the vehicle receives the restriction request signal from the electronic key, the use of the target device for in-vehicle verification is used. And gist that a limit applying means for adding a restriction to.

  According to this configuration, when the vehicle receives the ID signal transmitted from the electronic key located outside the vehicle by the communication master, the vehicle executes ID verification of the electronic key, and when this ID verification is established, the vehicle outside verification is established. In addition, the in-vehicle verification is also processed as established. Therefore, in this configuration, when the outside verification is established, the inside verification is also processed, so that one communication master is shared by both the outside verification and the in-vehicle verification. Therefore, the communication master is installed both outside and outside the vehicle. You do n’t have to. For this reason, the number of communication masters can be reduced.

  In addition, when an operation for forcibly canceling the verification outside the vehicle in the established state is executed with the electronic key, a restriction request signal is transmitted from the electronic key to the vehicle through communication of a system different from the ID verification. When the vehicle receives the restriction request signal from the electronic key, the vehicle forcibly cancels the outside-vehicle verification processed as being established for a certain period of time. Therefore, even if a malicious third party gets into the vehicle when the outside verification is in progress, if the in-vehicle verification is canceled using the electronic key, the in-vehicle verification is forcibly canceled. Without having to use a vehicle. For this reason, it is possible to ensure security against vehicle theft.

The gist of the present invention is that the communication distance of the separate system is set longer than the communication distance of the ID verification.
According to this configuration, since the communication distance of another system is set longer than that of the ID verification, even if the user is pushed away from the vehicle by a malicious third party, the restriction request signal is sent from that position. Can be delivered to the vehicle. Therefore, it is possible to ensure high security against vehicle theft.

The gist of the present invention is that the in-vehicle collation is established only for a predetermined time when the in-vehicle collation is established.
According to this configuration, when the vehicle outside verification is established, the vehicle interior verification is established only for a certain period of time, so it is not necessary to leave the vehicle interior verification for an extended period of time. Therefore, it is possible to ensure high security against vehicle theft.

The gist of the present invention is that the use restriction of the target device for in-vehicle collation is a restriction that disables starting of the engine of the vehicle.
According to this configuration, since the engine restriction is not allowed to start the engine, it is possible to make it difficult for a third party to get on and off the vehicle.

  In the present invention, the communication system for ID verification is short-range wireless communication that requires the electronic key to be established for communication, the communication master is disposed in a vehicle, and the ID verification is performed on the vehicle. The gist is to execute the electronic key by passing the electronic key over the communication master over the window glass.

  According to this configuration, since the ID verification is performed by holding the electronic key over the window glass to the communication master, it is possible to establish communication using the communication master as a mark of the electronic key. Therefore, it is possible to ensure the convenience of communication.

  According to the present invention, the number of communication masters mounted on a vehicle can be reduced, and security against vehicle theft can be ensured.

Hereinafter, an embodiment of an electronic key system embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, the vehicle 1 is provided with an electronic key system 3 that executes ID verification by short-range wireless communication with the electronic key 2. The near field communication is so-called NFC (Near Field Communication), and a communication method such as Felica, Mifare, Type B (all registered trademarks) is used.

  In this case, the vehicle 1 includes a key verification device 4 for verifying the ID code of the electronic key 2, a door lock device 5 for managing the locking / unlocking operation of the vehicle door, and an engine starter 6 for managing the operation of the engine. Provided, and these are connected via an in-vehicle bus 7. Among these, the key collating device 4 is provided with a collation ECU 8 that performs a collation operation of the ID code. The engine starter 6 is connected to an engine switch 9 that is operated when the power state of the vehicle 1 is switched. Note that the door lock device 5 corresponds to a target device to be verified outside the vehicle, and the engine starter 6 corresponds to a target device to be verified inside the vehicle.

  A reader / writer 10 is connected to the verification ECU 8 as a communication device on the vehicle 1 side of the electronic key system 3. The reader / writer 10 writes and reads various data to and from the electronic key 2 that is a communication partner. As shown in FIG. 2, the reader / writer 10 is disposed over the window glass 12 of the vehicle door 11 and is disposed above the door trim 13 of the vehicle door 11. Note that the reader / writer 10 corresponds to a communication master.

  As shown in FIG. 1, the reader / writer 10 is provided with a reader / writer control ECU 14 that manages short-range wireless communication with the electronic key 2. An antenna 16 for near field communication is connected to the reader / writer control ECU 14 via a communication circuit 15. The antenna 16 is a magnetic field antenna that transmits a magnetic field as a radio wave, and for example, a loop antenna is used. The antenna 16 is a transmission / reception antenna and transmits / receives radio waves in, for example, an HF (High Frequency) band. The antenna 16 includes a series resonant circuit of an antenna coil 17 and a capacitor 18. The communication circuit 15 modulates radio waves transmitted from the antenna 16 or demodulates radio waves received by the antenna 16.

  As shown in FIG. 3, the reader / writer 10 is installed in each of the driver seat and the passenger seat so that the electronic key 2 and ID verification can be executed from either the driver seat or the passenger seat. Since the reader / writer 10 is a magnetic field antenna in the HF band, it forms a substantially circular communication area Ea in plan view.

  As shown in FIG. 1, the electronic key 2 is a so-called IC tag that performs near field communication with the reader / writer 10. The electronic key 2 is provided with a communication control circuit 20 that manages the operation of the electronic key 2. In the communication control circuit 20, the ID code of the electronic key 2 is registered.

  An antenna 21 is connected to the communication control circuit 20 for near field communication. For example, a loop antenna is used as the antenna 21 as a kind of magnetic field antenna. The antenna 21 includes a parallel resonant circuit including an antenna coil 22 and a resonance capacitor 23. The antenna 21 is a transmission / reception antenna, and transmits and receives HF band radio waves, for example.

  When the electronic key 2 is located outside the vehicle, the reader / writer 10 intermittently transmits the drive radio wave Sv toward the outside of the vehicle. When receiving the drive radio wave Sv of the reader / writer 10, the electronic key 2 starts up the drive radio wave Sv as a power source and transmits an ID signal Sid from the antenna 21. The ID signal Sid includes the ID code of the electronic key 2. When the reader / writer control ECU 14 receives the ID signal Sid by the antenna 16, the reader / writer control ECU 14 transfers the ID code in the ID signal Sid to the verification ECU 8. When the ID code is input from the reader / writer control ECU 14, the verification ECU 8 performs ID verification. If ID verification is established, the verification ECU 8 processes that the verification outside the vehicle is established, and permits or executes door lock locking / unlocking.

  In addition, when the verification ECU 8 confirms that the verification outside the vehicle is established, the verification ECU 8 processes the verification inside the vehicle for a certain period of time. In-vehicle verification is ID verification performed between the electronic key 2 located in the vehicle and the vehicle 1. Therefore, when the vehicle outside verification is established, the vehicle interior verification is processed as established for a certain period of time, and therefore engine start is permitted during this time.

  The electronic key system 3 is provided with an in-vehicle collation canceling system 24 capable of canceling in-vehicle collation that is permitted when the external collation is established by manual operation (manual operation) of the user. The in-vehicle collation canceling system 24 of the present example is capable of forcibly canceling in-vehicle collation that has been established for a certain period of time due to the establishment of out-of-vehicle verification by a predetermined operation with the electronic key 2. In the case of this example, in-vehicle collation is also established for a certain period of time with the establishment of outside-vehicle collation, so there is no denying the possibility that a third party gets into the vehicle 1 by a third party while the in-vehicle collation is established, This is because the in-vehicle collation can be forcibly canceled by a predetermined operation of the electronic key 2 to cope with this.

  In this case, the electronic key 2 is provided with a release button 25 that is operated when the in-vehicle collation is forcibly released. The release button 25 is connected to the communication control circuit 20 using, for example, a momentary switch. For example, the release button 25 outputs an on signal when there is a button operation, and outputs an off signal when there is no button operation. The release button 25 constitutes detection means.

  The vehicle 1 is provided with a Bluetooth system 26 that wirelessly communicates with the electronic key 2 by Bluetooth (registered trademark). Bluetooth is a kind of short-range wireless communication technology used for connection between devices of about several meters, for example. Bluetooth has an advantage that, for example, radio waves in the 2.45 GHz band are used, and communication can be established if there is an obstacle between devices as long as the distance is about 10 m. Further, there is an advantage that power consumption can be reduced as compared with infrared communication such as IrDA (Infrared Data Association).

  In this case, the electronic key 2 is provided with a Bluetooth communication device 27 as a communication device on the electronic key 2 side of the Bluetooth system 26. The Bluetooth communication device 27 is connected to the communication control circuit 20, and the operation is managed by the communication control circuit 20. The Bluetooth communication device 27 operates using a battery 28 mounted on the electronic key 2 as a power source. For example, a button battery or the like is used as the battery 28. In addition, the Bluetooth communication apparatus 27 comprises a communication means (communication equipment).

  On the other hand, the vehicle 1 is provided with a Bluetooth communication device 29 as a communication device on the vehicle 1 side of the Bluetooth system 26. The Bluetooth communicator 29 is connected to the verification ECU 8 via an electric wiring inside the vehicle. In addition, the Bluetooth communication apparatus 29 comprises a communication means (communication equipment).

  The communication control circuit 20 is provided with a forced release request output unit 30 that transmits an in-vehicle verification forced release request Sa from the Bluetooth communication device 27 when the release button 25 is operated. The in-vehicle collation forcible release request Sa is a request for forcibly releasing the in-vehicle collation once established by the establishment of the out-vehicle collation. The in-vehicle verification forced release request Sa is transmitted, for example, a plurality of times each time the release button 25 is pressed. The in-vehicle collation forced release request Sa includes, for example, the ID code of the electronic key 2 and a function code that requests forcible release of in-vehicle collation establishment. The forced release request output unit 30 corresponds to a transmission control unit, and the in-vehicle verification forced release request Sa corresponds to a restriction request signal.

  The verification ECU 8 is provided with an in-vehicle verification forced release unit 31 for forcibly canceling the in-vehicle verification once established. When the in-vehicle verification compulsory canceling unit 31 receives the in-vehicle verification compulsory cancellation request Sa transmitted from the electronic key 2 with the Bluetooth communication device 29 in a situation where the in-vehicle verification is established, the in-vehicle verification is temporarily performed. Forcibly cancel. The in-vehicle verification forced release unit 31 corresponds to a restriction providing unit.

Next, the operation of the in-vehicle collation cancellation system 24 of this example will be described with reference to FIGS.
When the vehicle 1 is in a parked state (door lock locked, engine stopped), the reader / writer 10 intermittently transmits the drive radio wave Sv through the window glass 12 to the outside of the vehicle. The communication area Ea for the driving radio wave Sv is formed only in the very vicinity of the window glass 12. Actually, the driving radio wave Sv is transmitted to both sides in the left-right direction of the vehicle body in the reader / writer 10, but in this example, the radio wave on the window glass 12 side is used as the communication area Ea of the driving radio wave Sv for vehicle communication outside the vehicle. Use as

  At this time, as shown in FIG. 4, when the electronic key 2 is held from the outside of the vehicle over the window glass 12 to the reader / writer 10 and the electronic key 2 receives the driving radio wave Sv, it is activated by the driving radio wave Sv, and the ID signal Sid Is returned to the reader / writer 10. When the outside verification is established with this ID signal Sid, unlocking of the door lock is permitted. For this reason, when a door handle knob (not shown) outside the vehicle is touch-operated, the door lock is unlocked and boarding is permitted.

  When the verification outside the vehicle is established, the verification ECU 8 processes the verification inside the vehicle for a certain period of time. Therefore, if the vehicle outside verification is established, the engine can be started in a certain time. For this reason, if the user presses the engine switch 9 after getting on, the engine can be started.

  By the way, when the in-vehicle verification is processed as being established for a certain period of time with the establishment of the outside verification as in this example, as shown in FIG. Therefore, it is impossible to deny the possibility of getting into the vehicle 1 and getting on the vehicle 1 as it is. That is, when the user does not immediately get into the vehicle 1 after the vehicle outside verification is established, it is also assumed that a third party for the purpose of theft pushes away the user and gets on, gets on the engine and gets away.

  However, in the case of this example, when such a theft situation occurs, when the user is pushed away by a third party, the user operates the release button 25 to force in-vehicle verification that has been established for a certain period of time. To release. At this time, when the forced release request output unit 30 detects that the release button 25 has been pressed, the forced check request output unit 30 causes the Bluetooth communication device 27 to transmit an in-vehicle verification forced release request Sa. The in-vehicle verification forced release request Sa is transmitted through a communication network called Bluetooth, which has a long communication distance. Therefore, even if the user is pushed away from the vehicle 1 by a third party, the in-vehicle verification forced release request Sa is a problem up to the vehicle 1. It arrives without.

  When the verification ECU 8 receives the in-vehicle verification forced release request Sa transmitted from the electronic key 2 via the Bluetooth communication device 29, the verification ECU 8 operates based on the in-vehicle verification forced cancellation request Sa to forcibly cancel the in-vehicle verification once established. To do.

  For this reason, even if a third person who rides away from the user pushes the engine switch 9, the engine does not start because the in-vehicle collation is not established. Therefore, the vehicle 1 is not escaped by a third party.

  As described above, in this example, when the reader / writer 10 installed on the vehicle door 11 is matched with the electronic key 2 and the vehicle outside verification, the vehicle startup verification is permitted for a certain period of time, and the engine start operation can be performed. Therefore, since the reader / writer 10 prepared for the outside of the vehicle is shared not only for the outside of the vehicle but also for the inside of the vehicle, it is not necessary to prepare a reader / writer separately inside and outside the vehicle. For this reason, since it becomes possible to suppress the number of reader / writers installed in the vehicle 1, it is possible to reduce the component cost.

  In addition, a communication system for Bluetooth communication is provided between the vehicle 1 and the electronic key 2 as a communication system other than the short-range wireless communication used for ID verification. When the release button 25 of the electronic key 2 is operated, the in-vehicle collation forced release request Sa is transmitted from the electronic key 2 to the vehicle 1 via Bluetooth, and the in-vehicle collation that has been established for a certain time is forcibly released. Therefore, when the user establishes the outside verification, even if the vehicle 1 is unexpectedly boarded by the third party for the purpose of vehicle theft, if the release button 25 is operated by the user, the engine cannot be started. Is done. Therefore, since it is not necessary for a third party to ride on the vehicle 1 as it is, the security against vehicle theft can be ensured.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) When the collation outside the vehicle is established by the reader / writer 10, the inside collation is also processed to be established at a certain time, so that one reader / writer 10 is shared outside the vehicle and outside the vehicle. Can do. In addition, even if the in-vehicle verification is processed as being established for a certain period of time after the vehicle outside verification is established, this function can be forcibly released by operating the release button 25. Therefore, even if a third party unexpectedly gets into the vehicle 1 under the situation where the outside verification is established, by operating the release button 25, it is possible to forcibly cancel the establishment of the in-vehicle verification and disable the engine start. is there. Accordingly, security against vehicle theft can be ensured.

  (2) Since the communication system of the in-vehicle verification forced release request Sa is Bluetooth communication and the communication distance is longer than that of ID verification communication, even if the third party is pushed away from the vehicle 1, The verification forced cancellation request Sa can be sent to the vehicle 1. Therefore, the forcible release of in-vehicle verification can be performed more reliably.

  (3) When in-vehicle verification is established, in-vehicle verification is established only for a certain period of time, so it is not necessary to keep in-vehicle verification for an unnecessarily long time. Therefore, high security against vehicle theft can be ensured.

  (4) Since the engine cannot be started when the in-vehicle verification is forcibly canceled, the engine is started by forcibly canceling the in-vehicle verification even if the user gets into the vehicle 1 unexpectedly. You do n’t have to. Therefore, it is possible to further prevent the third person from getting on and off the vehicle 1.

  (5) Since the electronic key system 3 is a system conforming to short-range wireless communication and the ID verification is performed by holding the electronic key 2 over the window glass 12 over the reader / writer 10 in the vehicle, the reader / writer 10 is Communication can be established as a mark of the electronic key 2. Therefore, since the holding point of the electronic key 2 can be known immediately, the convenience of the operation imposed on the user at the time of ID collation can be ensured.

(6) Since the Bluetooth communication with high noise resistance is used for the communication of the in-vehicle verification forced release request Sa, the in-vehicle verification forced release request Sa can be transmitted to the vehicle 1 more reliably.
(7) Since the transmission trigger of the in-vehicle verification forced cancellation request Sa is the button operation with the electronic key 2, the establishment of the in-vehicle verification can be forcibly canceled by a very clear operation for the user to press the release button 25. it can.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
As shown in FIG. 6, at the time of verification outside the vehicle, the battery information Sb is included in the ID signal Sid to notify the vehicle 1 about the presence or absence of the battery, and if the electronic key 2 falls out of battery, verification outside the vehicle Even if is established, establishment of in-vehicle verification for a certain period of time may not be executed. In this case, when the electronic key 2 is out of battery, that is, when the Bluetooth communication device 27 cannot operate and the forced release of the in-vehicle verification is not effective, it is not necessary to temporarily establish the in-vehicle verification. Security can be further improved.

  At this time, the in-vehicle collation is executed, for example, by holding the electronic key 2 over the reader / writer 10 from the inside of the vehicle. The discrimination between in-vehicle verification and external verification in the reader / writer 10 can be detected by a sensor, for example. Alternatively, after the engine switch 9 is pressed, holding the electronic key 2 over the reader / writer 10 can be used for in-vehicle verification.

The confirmation as to whether or not the electronic key 2 is out of battery may be performed, for example, by actually trying Bluetooth communication and confirming whether communication is established.
The operation imposed on the user when forcibly unlocking the in-vehicle verification is not limited to the button operation with the electronic key 2. As shown in FIG. 7, for example, an operation (vibration operation) for vibrating the electronic key 2 in a predetermined pattern may be used. In this case, when the vibration sensor 51 is provided on the electronic key 2 and the vibration sensor 51 detects that the electronic key 2 has been vibrated in a predetermined pattern, an in-vehicle verification forced release request Sa is sent from the electronic key 2 to the vehicle 1. Sent.
