Description

The present invention relates to a collating device.

As in Patent Document 1, an electronic key system for exchanging a wireless signal between an electronic key and an in-vehicle device is well known.
The collation device provided in the in-vehicle device collates the information contained in the wireless signal exchanged with the electronic key with the information stored in itself. When the collation is established, the collation device transmits a signal including information indicating that fact to each device in the vehicle. With the reception of this signal as a trigger, each device in the vehicle operates or is allowed to operate.

Japanese Unexamined Patent Publication No. 2014-91434

There are usually multiple types of collation performed by the collating device. For example, vehicle interior verification performed to allow the engine to be switched from off to on, vehicle interior D seat verification or vehicle exterior P seat verification to be performed to allow the switching of vehicle door lock / unlock, electronic A switch provided on the key is operated, and remote collation or the like is performed to operate an in-vehicle device corresponding to the switch.

Normally, the collation device cannot process a plurality of collations at the same time, and therefore collates based on a predetermined fixed order. In the above collation example, the vehicle interior collation, the vehicle interior D seat collation, the vehicle interior P seat collation, and the remote collation are collated in this order, and the vehicle interior collation is performed again.

However, in such a collation device, for example, even if a vehicle user approaches the vehicle in order to perform P-seat collation outside the vehicle interior to switch the vehicle door from locked to unlocked, the collation device may be used depending on the timing. It may take some time before the P seat verification outside the passenger compartment is carried out. Then, it may take time for the vehicle door to be switched from locked to unlocked. In such a case, the user may be dissatisfied with the convenience of the device.

An object of the present invention is to provide a collation device that is less likely to cause dissatisfaction to a user.

In order to solve the above problem, in a collation device that allows the operation of the on-board device mounted on the mounting target by collation via wireless communication performed with the electronic key, the collation via wireless communication is performed. There are a plurality of different types, and based on the communication state with the electronic key and at least one of the states of the mounting target, the collation that is likely to be established is determined, and the collation is more likely than the collation that is unlikely. The gist is to give priority to high verification.

According to this configuration, the collation with a high possibility is prioritized over the collation with a low possibility of being established. As a result, the time required for the collation to be established is shortened as compared with the case where the collation order is fixed as in the conventional case. As a result, the time required for the on-board device to be allowed to operate is shortened, so that the user is less likely to be dissatisfied with the convenience of the on-board device. That is, the collation device having this configuration has an effect that it is less likely to cause dissatisfaction to the user.

In the above configuration, for collation via the wireless communication, internal communication collation that is possible by entering the electronic key into the internal communication area set inside the mounting target and setting outside the mounting target. The external communication collation that is made possible by the electronic key entering the external communication area is included, and there is a possibility that either the internal communication collation or the external communication collation can be established from the state of the mounting target. Is high, and priority is given to verification with high possibility over verification with low possibility. If the internal communication verification is established, the operation of the internal communication compatible device as the on-board device is allowed. When the external communication collation is established, the operation of the external communication compatible device as the on-board device is allowed.

According to the collation device having this configuration, the collation required for using the device having high usability is performed first as compared with the case where the collation order is fixed as in the conventional case. As a result, the operation of the on-board device desired by the user is likely to be permitted more quickly, and the possibility that the user is dissatisfied with the convenience of the device is reduced. That is, the collation device having this configuration has an effect that it is less likely to cause dissatisfaction to the user.

In the above configuration, the collation via the wireless communication includes a remote communication collation performed by operating the electronic key, and can be a collation with a high possibility of the internal communication collation and the external communication collation. The remote communication collation is performed with the collation having a low property, and when the remote communication collation is established, the operation of the remote communication compatible device as the on-board device is allowed.

According to this configuration, the remote communication collation is performed higher than the collation having the lower priority among the internal communication collation and the external communication collation. Therefore, when the electronic key is operated, the remote communication verification is likely to be established quickly, and the time required for the operation of the remote communication compatible device to be permitted is short.

In the above configuration, of the internal communication collation and the external communication collation, the most probable collation is tried more times than the less probable collation.
According to this configuration, even if the wireless communication is momentarily unsuccessful due to the influence of noise on the wireless signal, the most probable verification among the internal communication verification and the external communication verification is tried many times. , The possibility that the collation will be established increases. For this reason, the operation of the device desired by the user is likely to be permitted, and the possibility that the user is dissatisfied with the convenience of the device is reduced. In other words, the collating device having this configuration has the effect of being less likely to cause dissatisfaction with the user.

The collation device of the present invention has an effect that it is less likely to cause dissatisfaction to the user.

Further, when the electronic key control unit 11 recognizes the unlock signal generated by the operation of the unlock switch 15, the electronic key control unit 11 uses the encryption key to transmit the ID code and the information indicating that the vehicle door is switched from the lock to the unlock. A remote signal SrkeUL including the calculated and encrypted unlock code is generated, and this is wirelessly transmitted through the UHF transmission unit 13.

<On-board unit>
As shown in FIG. 1, the vehicle-mounted device 20 includes an vehicle-mounted control unit 21, an LF transmission unit 22, a UHF reception unit 23, a start switch 24, an antenna coil 25, a courtesy switch 26, a brake pedal 27, and the like. It includes a door handle sensor 28, a door lock device 29, and an engine device 30. The LF transmitter 22, the UHF receiver 23, the start switch 24, the antenna coil 25, the courtesy switch 26, the brake pedal 27, the door handle sensor 28, the door lock device 29, and the engine device 30 are electrically connected to the vehicle-mounted control unit 21, respectively. It is connected to the. The in-vehicle device 20 corresponds to the mounting target.

The LF transmission unit 22 modulates the electric signal (request signal) generated by the vehicle-mounted control unit 21 into an LF band radio signal, and transmits the modulated radio signal toward the set communication area.
The LF transmission unit 22 includes an in-vehicle LF transmission unit 221, an outside vehicle D seat side LF transmission unit 222, and an outside vehicle P seat side LF transmission unit 223. The difference between these transmission units is that the communication area for transmitting the LF band radio signal is different.

As shown in FIG. 2, the in-vehicle LF transmission unit 221 transmits a request signal toward the in-vehicle communication area S1 set in the boarding space of the vehicle 2. The LF transmission unit 222 on the outside D seat side transmits a request signal to the communication area S2 on the outside D seat side set on the outside of the vehicle door of the driver's seat (D seat). The LF transmission unit 223 on the outside P seat side transmits a request signal to the communication area S3 on the outside P seat side set on the outside of the vehicle door of the passenger seat (P seat). The in-vehicle communication area S1 corresponds to an internal communication area, and the outside D-seat side communication area S2 and the outside P-seat side communication area S3 correspond to an external communication area.

As shown in FIG. 1, the UHF receiving unit 23 receives a radio signal in the UHF band and demodulates the received signal into an electric signal.
The start switch 24 is a switch that is pushed and operated, and generates a start signal that is an electric signal indicating that the switch is operated.

The antenna coil 25 is provided so as to surround the start switch 24. The antenna coil 25 emits a driving radio wave to the IC tag 16 provided on the electronic key 10 and receives the reflected wave from the IC tag 16. The reflected wave includes an ID code.

The courtesy switch 26 detects the opening / closing of the vehicle door and generates an opening / closing state signal which is an electric signal indicating the opening / closing state.
The brake pedal 27 is provided under the foot of the driver's seat and is mainly operated by stepping on the foot, and generates a brake signal which is an electric signal indicating that the stepping operation is performed.

When the door handle sensor 28 detects contact with the door handle, the door handle sensor 28 generates a contact signal to that effect.
The door lock device 29 switches between locking and unlocking the vehicle door. The door lock device 29 corresponds to an on-board device, an external communication compatible device, and a remote communication compatible device.

The engine device 30 switches on / off the engine, which is a drive source for traveling the vehicle 2. The engine device 30 corresponds to an on-board device and an internal communication compatible device.
In the memory 21a of the vehicle-mounted control unit 21, the same ID code as the ID code set in the corresponding electronic key 10 and the same encryption key as the encryption key set in the electronic key 10 are stored. The encryption key is used for calculation of the response code and decryption of the lock code and the unlock code. The encryption key used for calculating the response code and the encryption key used for decrypting the lock code and the unlock code may be the same key or different keys. Then, the in-vehicle control unit 21 determines the success or failure of whether or not the electronic key 10 which is the communication partner is a legitimate one based on the ID code collation and the response collation. Further, the in-vehicle control unit 21 determines the success or failure of whether or not the electronic key 10 which is the communication partner is legitimate based on the ID code collation and the lock code collation, or the ID code collation and the unlock code collation. ..

The in-vehicle control unit 21 performs vehicle interior collation, D-seat polling collation, and P as collation for determining the success or failure of the electronic key 10 which is the communication partner based on the ID code collation and the response collation. Perform seat polling verification.

Further, the in-vehicle control unit 21 determines the success or failure of whether or not the electronic key 10 which is the communication partner is legitimate based on the ID code verification and the lock code verification, or the ID code verification and the unlock code verification. Perform remote key verification as verification.

The vehicle-mounted control unit 21 performs all-seat polling collation to determine whether or not the ack signal Sac can be received for the transmitted wake signal Swk and the vehicle ID signal Svi.

Further, the in-vehicle control unit 21 determines the success or failure of whether or not the electronic key 10 which is the communication partner is legitimate based on the collation of the ID code included in the reflected wave with respect to the radio wave emitted from the antenna coil 25. Perform trapon collation as collation.

As shown in each of FIGS. 3 (a) to 3 (g), the vehicle-mounted control unit 21 collates six types depending on the difference in situations such as the positional relationship between the vehicle 2 and the user who possesses the electronic key 10. Change the priority of. The in-vehicle control unit 21 corresponds to a collation device.

Next, the mode of changing the collation priority in the vehicle-mounted control unit 21 and the effect associated with the change will be described.
As shown in FIG. 3A, in a so-called parking state in which the power supply of the vehicle 2 is all off, the vehicle doors are all closed, and the vehicle is locked, the vehicle-mounted control unit 21 performs all-seat polling verification and remote key verification. , D seat polling verification, P seat polling verification, vehicle interior verification, and transponder verification are performed in this order.

In the parked state, it is difficult to imagine a situation where there is a user in the passenger compartment. On the other hand, it is assumed that a user outside the vehicle approaches the vehicle in order to use the vehicle. In the parked state, as described above, by giving priority to all-seat polling verification, it is easy to quickly establish the verification performed when the user outside the vehicle approaches the vehicle in order to use the vehicle.

When all-seat polling verification is established in the parking state shown in FIG. 3A, the vehicle-mounted control unit 21 shifts to the boarding intention confirmation state as shown in FIG. 3B. In the boarding intention confirmation state, the vehicle-mounted control unit 21 performs each collation in the order of D seat polling collation, P seat polling collation, remote key collation, all seat polling collation, vehicle interior collation, and transponder collation.

In this boarding intention confirmation state, it is assumed that the user holding the electronic key 10 touches the door handle in order to switch the vehicle door from locked to unlocked in order to board the vehicle. In this boarding intention confirmation state, by giving priority to the D seat polling verification and the P seat polling verification as described above, when the user approaches the vehicle to touch the door handle of the vehicle door, these D seat polling verifications and P-seat polling verification is likely to be established quickly. As a result, when the user touches the door handle and detects it through the door handle sensor 28, the vehicle-mounted control unit 21 can quickly switch the vehicle door from lock to unlock through the door lock device 29.

Upon recognizing that the D seat polling collation or the P seat polling collation was established in the boarding intention confirmation state shown in FIG. 3B and the vehicle door was shifted to the open state through the courtesy switch 26, the vehicle-mounted control unit 21 showed FIG. As shown in (c) and FIG. 3 (d), the vehicle shifts to the boarding confirmation state (engine start waiting state). In the boarding confirmation state, the vehicle-mounted control unit 21 performs each collation in the order of vehicle interior collation, transponder collation, remote key collation, D seat polling collation, P seat polling collation, and all seat polling collation.

In this boarding confirmation state, it is assumed that the user gets on board and starts the engine. Therefore, by giving priority to the vehicle interior collation and the transponder collation as described above, the vehicle interior collation and the transponder collation can be quickly performed with the electronic key 10 possessed by the user who got on the vehicle before the start switch 24 is operated. It is easy to establish. As a result, when the user operates the start switch 24 and detects it, the vehicle-mounted control unit 21 can quickly drive the engine, which is the driving source for traveling the vehicle 2, through the engine device 30.

As shown in FIGS. 3 (c), 3 (d), and 3 (e), the in-vehicle control unit 21 may determine whether the user is in the boarding state or the disembarking state in the boarding confirmation state. No. That is, even immediately after the user starts the engine, then stops the engine, the power supply of the vehicle 2 is all off, and the vehicle gets off (the state shown in FIG. 3E), the boarding confirmation state is obtained.

When it is recognized that the vehicle door is closed through the courtesy switch 26 in the boarding confirmation state shown in FIG. 3 (e), the vehicle-mounted control unit 21 shifts to the boarding intention confirmation state as shown in FIG. 3 (f). In the boarding intention confirmation state, similarly to the boarding intention confirmation state shown in FIG. 3B, the in-vehicle control unit 21 performs D seat polling verification, P seat polling verification, remote key verification, all seat polling verification, vehicle interior verification, and transponder. Perform each collation in the order of collation.

In this boarding intention confirmation state, it is assumed that the user holding the electronic key 10 touches the door handle in order to switch the vehicle door from unlocking to locking in order to leave the vehicle after getting off. In this boarding intention confirmation state, by giving priority to the D seat polling verification and the P seat polling verification as described above, the D seat polling verification and the P seat polling verification are promptly performed with the electronic key 10 possessed by the user. It is easy to establish. As a result, when the user touches the door handle and detects it through the door handle sensor 28, the vehicle-mounted control unit 21 can quickly switch the vehicle door from unlocked to locked through the door lock device 29.

Even after the vehicle door is switched from unlocked to locked, the vehicle-mounted control unit 21 maintains the boarding intention confirmation state. This is because it is assumed that the user touches the door handle again to switch the vehicle door from locked to unlocked, such as when the user forgets something in the vehicle.

As shown in FIG. 3 (g), when recognizing a state in which the power supply of the vehicle 2 is all off, all the vehicle doors are closed, the vehicle is further locked, and all the above-mentioned six collations are not established, the vehicle-mounted control unit 21 , Move to the parked state.

As described above, the vehicle-mounted control unit 21 is a vehicle such as a communication state between the vehicle-mounted device 20 and the electronic key 10, a locked / unlocked state of the vehicle door, an engine driving state, and an open / closed state of the vehicle door. Based on the state of 2, the collation that is likely to be established is determined, and the collation that is likely to be established is prioritized over the collation that is unlikely to be established. As a result, the user is dissatisfied with the convenience of the device because the collation required to use the device with high usability is performed first as compared with the case where the collation order is fixed as in the conventional case. The risk of holding is reduced. In other words, the vehicle-mounted control unit 21 of this example has the effect of being less likely to cause dissatisfaction with the user.

As shown in each figure of FIGS. 3 (a) to 3 (g), the in-vehicle control unit 21 performs internal communication collation and external communication in all states of the parking state, the boarding intention confirmation state, and the boarding confirmation state. Remote key matching is performed between high-priority matching and low-priority matching among communication matching.

The remote signal that serves as a trigger for performing the remote key collation is generated by the user operating the lock switch 14 or the unlock switch 15 provided on the electronic key 10. That is, the remote key verification is attempted by the user's will regardless of the state of the vehicle 2 and the positional relationship between the vehicle 2 and the electronic key 10. Therefore, by performing the internal communication collation and the external communication collation between the high-priority collation and the low-priority collation, the remote key collation can be quickly performed when the user operates the lock switch 14 or the unlock switch 15. Easy to hold. This is because the remote key collation is performed higher than the collation having the lower priority among the internal communication collation and the external communication collation. Therefore, when the lock switch 14 or the unlock switch 15 provided on the electronic key 10 is operated, the vehicle door is quickly switched from lock to unlock or from unlock to lock.

The above embodiment may be changed as follows.
-In the above embodiment, the vehicle-mounted control unit 21 performs each of the all-seat polling collation, the remote key collation, the D-seat polling collation, the P-seat polling collation, the vehicle interior collation, and the transponder collation once. May be carried out. That is, the collation that is expected to be established may be performed a plurality of times.

For example, as shown in FIG. 4A, the vehicle-mounted control unit 21 performs all-seat polling verification a plurality of times (here, twice) when the vehicle is in a parked state. Further, as shown in FIG. 4B, when the vehicle-mounted control unit 21 is in the boarding intention confirmation state, the D-seat polling check and the P-seat polling check are performed a plurality of times (here, twice). Further, as shown in FIG. 4C, the vehicle-mounted control unit 21 performs the vehicle interior collation and the transponder collation a plurality of times (here, twice) when the vehicle is in the boarding confirmation state. With this configuration, for example, the wireless signal exchanged between the electronic key 10 and the on-board unit 20 is affected by noise, and even if the wireless communication is momentarily unsuccessful, it may be established. Higher collations are more likely to be successful because they are tried more often. Therefore, it is easy to operate the desired device or to be in a state where the operation is permitted. This reduces the risk that the user will be dissatisfied with the convenience of the device. In other words, the vehicle-mounted control unit 21 has the effect of being less likely to cause dissatisfaction with the user.

-In the above alternative example, as shown in each figure of FIGS. 4 (a) to 4 (c), the high-priority collation performed a plurality of times performs the remote key collation when the previous collation is unsuccessful. After the implementation, try the high-priority collation. This increases the possibility that the collation will be established by shifting the timing of the collation and improving the positional relationship between the electronic key 10 and the vehicle-mounted device 20.

-In the above embodiment, the vehicle-mounted control unit 21 performs both high-priority and low-priority collation, but it is not necessary to carry out low-priority collation. For example, as shown in FIG. 5A, the vehicle-mounted control unit 21 performs only all-seat polling collation and remote key collation when the vehicle is parked, and does not perform other collation. Further, as shown in FIG. 5B, the in-vehicle control unit 21 performs D-seat polling collation, P-seat polling collation, and remote key collation when the boarding intention confirmation state is performed, and does not perform other collation. .. Even with such a configuration, it is easy for the user to operate the desired device or to be in a state where the operation is permitted.

The other example may be combined with the above embodiment. For example, when the vehicle-mounted control unit 21 is in the boarding confirmation state, as shown in FIG. 5 (c), only three collations of vehicle interior collation, transponder collation, and remote key collation are performed, and FIG. 3 (c). As shown in the above, it is combined with the case of performing 6 collations of vehicle interior collation, transponder collation, remote key collation, D seat polling collation, P seat polling collation, and all seat polling collation. Even with such a configuration, the same effect as that of the above embodiment can be obtained, and even if it is affected by noise or the like, collation is likely to be established.

-In the above embodiment, either one of the vehicle interior collation and the transponder collation, which are internal communication collations, may be omitted.
-In the above embodiment, any one or two of the external communication collation, that is, all-seat polling collation, D-seat polling collation, and P-seat polling collation may be omitted.

-In the above embodiment, if any one of the internal communication collations is established, it may be treated as if the other is also established. For example, the vehicle-mounted control unit 21 may treat that the transponder collation is also established when the vehicle interior collation is established.

-In the above embodiment, if any one of the D-seat polling check and the P-seat polling check that constitutes the external communication check is established, it may be treated as if the other is also established. That is, when the D-seat polling check is established, the in-vehicle control unit 21 may treat the P-seat polling check as being established.

-In the above embodiment, the remote key collation is performed between the collation with high possibility and the collation with low possibility among the internal communication collation and the external communication collation, but the timing is not limited to this. It may be performed in a lower order than the less likely collation, or it may be performed in a higher order than the most probable collation.

-In the above embodiment, the door lock device 29 has been described as a remote communication compatible device, but the present invention is not limited to this. For example, when the electronic key 10 is equipped with a switch for switching the on / off of the engine, the engine device 30 corresponds to a remote communication compatible device.

-In the above embodiment, the remote communication compatible device is the door lock device 29 which is also an external communication compatible device, but it does not necessarily have to be an external communication compatible device and may be an internal communication compatible device. Further, the device may be mounted on the vehicle 2 separately from the external communication compatible device and the internal communication compatible device.

-In the above embodiment, remote key verification may be omitted.
-In the above embodiment, the vehicle 2 is illustrated as the mounting target, but it may be a house or the like as well as the vehicle 2. That is, it may be applied to an electronic key system for a house instead of the electronic key system 1 for a vehicle.

-In the above embodiment, the vehicle-mounted control unit 21 corresponding to the collation device is provided on the vehicle-mounted device 20 on which the door lock device 29 and the engine device 30 corresponding to the mounted equipment are mounted, but the vehicle-mounted control unit 21 corresponding to the mounting target is not necessarily mounted. It does not have to be provided on the machine 20. For example, the function corresponding to the collation device may be provided in the electronic key 10, or may be provided in an external device other than the electronic key 10 and the vehicle-mounted device 20. Further, the electronic key 10, the vehicle-mounted device 20, or a part of the external device is not limited to those provided with a function corresponding to the collation device. The electronic key 10, the vehicle-mounted device 20, and the external device may exist independently as a collation device.

Next, the technical idea recalled from the above embodiment and the above alternative example will be described.
(B) The collation device shall perform only the most probable collation among the internal communication collation and the external communication collation, and shall not perform the less probable collation.

(B) The collation device shall repeatedly perform a collation with a high possibility among the internal communication collation and the external communication collation a set number of times, and then perform a collation with a low possibility.
