JP5928876B2 - Keyless entry system - Google Patents

Description

  The present invention relates to a keyless entry system.

  The keyless entry system is also called a smart keyless entry system, and even without using a mechanical key, authentication (or verification) is performed by wireless communication between the portable device owned by the user and the in-vehicle device installed in the vehicle. Then, based on the authentication result, it is possible to perform operations desired by the user, such as door unlocking, trunk opening, and engine starting.

  On the other hand, when the user loses or steals the portable device, there is a risk that a third party who has illegally acquired the portable device may be damaged by vehicle entry or vehicle theft.

  Therefore, authentication by wireless communication between the above-described portable device and the vehicle-mounted device, user face authentication, and communication between the portable device and the vehicle-mounted device via the human body and the vehicle body when the user touches the door knob (human body communication) A keyless entry device that unlocks the door when all the authentication results are valid is disclosed (see Patent Document 1).

JP 2011-032782 A

  In the configuration of Patent Document 1, it is necessary to perform authentication three times, and the processing may be complicated. In addition, in order to perform human body communication, it seems that there are not a few users who feel resistance to inducing an electric field on the surface of the human body or passing a weak current through the human body. Furthermore, it is necessary to create a database for user face authentication. When a user wants to use the vehicle suddenly, a user who is not registered in the database may not be able to use it immediately. It also leads to a decline.

  Against the background of the above problems, an object of the present invention is to provide a keyless entry system with improved security at a low cost without impairing user convenience.

Means for Solving the Problems and Effects of the Invention

A keyless entry system for solving the above problems is a keyless entry system including an in-vehicle device mounted in a vehicle and two or more portable devices that can be identified by the in-vehicle device and carried by a user. The in-vehicle device is included in the in-vehicle device side transmission unit that transmits a search signal for searching for a portable device, the in-vehicle device side reception unit that receives a response signal from the portable device for the search signal, and the received response signal A collation unit that performs collation using identification data for identifying a portable device to be identified and collation data associated with a pre-stored portable device, and the collation unit performs a predetermined first collation When the condition is satisfied, the response signal from the portable device received by the in-vehicle device side reception unit is set as the first response signal, the first verification is performed using the first response signal, and the predetermined response is determined in advance. When the second verification execution condition is satisfied, the response signal from the portable device other than the portable device that is the transmission source of the first response signal received by the in-vehicle device side receiving unit is set as the second response signal, An operation control information output unit that performs second verification using the two response signals, and outputs operation control information regarding whether or not various functions of the vehicle are permitted to operate based on the results of the first verification and the second verification; Assuming that.

With the above configuration, since the two portable devices need to be collated, the illegality from the outside such as communication interception can be more than twice as confidential as the portable device. Since two portable devices are physically required, two users each possess one by one, and it becomes difficult to receive damage such as theft. The following effects can also be expected.
・ If two portable devices are required to open the glove box and trunk, the user may leave the car at the hotel parking clerk if the user has another key. Disappear.
・ When lending a car to a friend or family member, you will not be able to see the driving history, trunk, or glow box of the navigation device.

  The keyless entry system of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of the keyless entry system 100. The keyless entry system 100 includes an in-vehicle device 1 mounted on a vehicle 101 and a plurality of portable devices (2, 3) possessed by a user.

  The in-vehicle device 1 includes an ECU 10, an LF transmission unit 11, a UHF reception unit 12, a memory 14 composed of a nonvolatile storage medium such as a flash memory, an engine switch 15, and a door antenna 16 (a general term for 16FR, 16FL, 16RR, 16RL). , Indoor antenna 17 (generic name for 17a and 17b: see FIGS. 7 and 8), trunk antenna 18, trunk antenna 19 and the like.

  The ECU 10 is composed of a well-known CPU, ROM and RAM storing various programs (collectively referred to as “vehicle-mounted device control program”), a signal input / output circuit (both not shown), and a nonvolatile storage medium. The computer includes a memory 10a (see FIG. 2) and the like. And various functions as the vehicle-mounted device 1 are realized by the CPU executing the vehicle-mounted device control program. The ECU 10 corresponds to a collation unit and a transmission area specifying unit of the present invention.

  The LF transmission unit 11 transmits a radio signal such as a search signal to the portable device 2 using, for example, an LF (long wave) band radio wave. The radio signals transmitted from the LF transmitter 11 are in the vicinity of the door (outside the vehicle compartment), inside the vehicle cabin, and inside the trunk via the door antenna 16, the indoor antenna 17, the antenna 18 inside the trunk, and the antenna 19 outside the trunk, respectively. , It reaches only within a limited transmission area near the outside of the trunk. The LF transmission unit 11 corresponds to the in-vehicle device side transmission unit of the present invention.

  The relationship between the arrangement of each antenna and the transmission area will be described with reference to FIG. The door antennas 16 (16FR, 16FL, 16RR, 16RL) are located outside the vehicle 101, near the driver's seat door (R1), near the passenger seat door (R2), near the right rear seat door (R3), and left rear portion, respectively. The vicinity of the seat door (R4) is the transmission area. The indoor antenna 17 has a transmission area (not shown) in which 17a is near the front seat (driver's seat and front passenger seat) and 17b is near the rear seat. The trunk antenna 18 has a trunk area as a transmission area (not shown). The trunk outside antenna 19 uses the outside of the vehicle behind the trunk as a transmission area (R5).

  For example, the search signal is first transmitted in the order of the door antenna 16 (16FR → 16FL → 16RR → 16RL) → antenna outside the trunk 19, and then transmitted in the order of the indoor antenna 17 → the antenna inside the trunk 18. Thereby, it can be specified to which transmission area the search signal is transmitted. That is, when the response signal from the portable device is received, the location of the portable device can be specified.

  Returning to FIG. 1, the UHF receiving unit 12 receives a radio signal transmitted from the portable device 2 in a radio wave of, for example, a UHF (ultra-high frequency) band (which may be a high frequency band other than the UHF band). Thereby, even if the output level of the portable device 2 is relatively weak, a communication distance can be obtained correspondingly, and the response signal can be more reliably transmitted to the in-vehicle device 1 side. The UHF receiving unit 12 corresponds to the in-vehicle device side receiving unit of the present invention.

  The engine switch 15 is a switch operated by the user when starting the engine. When the operation of the engine switch 15 is detected by a signal from the engine switch 15, the ECU 10 is permitted to start the engine. If the engine start is permitted, an engine start signal is transmitted from the ECU 10 to the engine control system.

  The portable device 2 (the same applies to the portable device 3) includes a control unit 20, an LF reception unit 21, a UHF transmission unit 22, a changeover switch 24, a memory 30 including a nonvolatile storage medium such as a flash memory, and the like. In addition, a switch / button for performing a so-called keyless function such as door locking / unlocking or trunk opening operation may be provided.

  The control unit 20 is configured as a computer including, for example, a well-known CPU, a ROM or RAM in which various programs (collectively referred to as “portable device control program”) are stored, and a signal input / output circuit (none of which are shown). Is done. And various functions as the portable device 2 are realized by the CPU executing the portable device control program.

  The LF receiving unit 21 receives a radio signal transmitted from the in-vehicle device 1 using an LF band radio wave. The UHF transmission unit 22 transmits a radio signal to the in-vehicle device 1 using UHF band radio waves.

  The changeover switch 24 is for setting whether to transmit the first response signal and the second response signal in the portable device (2 or 3). It may be exposed to the outside of the portable device so that it can be set by the user, or may be mounted as a DIP switch on the substrate and set in advance at the time of product shipment.

  For example, when the changeover switch 24 is set to the “first response signal” side (for example, closed state), the first response is received together with identification data for identifying the portable device when the search signal from the in-vehicle device 1 is received. Data indicating a signal is transmitted via the UHF transmitter 22. Alternatively, only when the first search signal from the in-vehicle device 1 is received, a response signal (data indicating that it is the first response signal may not be included) is transmitted. The same applies when the changeover switch 24 is set to the “second response signal” side (for example, open state).

  FIG. 2 is a block diagram showing a connection configuration between the ECU 10 of the in-vehicle device 1 and other in-vehicle devices. In addition to the engine switch 15 described above, the ECU 10 includes a door state detection unit 41, an audio device 51, a navigation device 52, an air conditioner control unit 53, a trunk opening / closing control unit 54, a glove box opening / closing control unit 55, and a fuel lid opening / closing control unit 56. The hood opening / closing control unit 57 and the engine control unit 58 are connected so that data communication is possible. The ECU 10 and these control units, devices, and the like may be directly connected, or may be connected via a known in-vehicle LAN via a communication I / F (interface) 10b.

  The door state detection unit 41 detects the open / closed state of each door of the vehicle 101 and is configured by, for example, a mechanical switch. The door state detection unit 44 can detect that the user has boarded the vehicle 101. In addition to the door state detection unit 44, a user's boarding may be detected using a seating sensor, a camera, or the like provided in a seat in the vehicle interior.

  Since the configuration of the audio device 51 is well known, detailed description thereof is omitted. Of course, a television may be included, or the navigation device 52 may be configured to be linked.

  The navigation device 52 detects the position of the vehicle, displays its current position on the electronic map data, and provides route guidance to the set destination. Since its configuration is well known, Detailed explanation is omitted.

  The air conditioner control unit 53 becomes operable when it receives an operation permission signal from the ECU 10, and drives and controls the air conditioner based on an operation signal from an operation unit (not shown) operated by the user. In addition to adjusting the temperature and humidity in the passenger compartment, conditioned air is blown (defrosted) to the windshield to remove condensation and frost.

  The trunk opening / closing control unit 54 controls the operation of an electromagnetic trunk opener that uses an electric motor, for example, which can automatically open and close the trunk lid by a remote operation of a driver's seat switch or a remote opener.

  As with the trunk opening / closing control unit 54, the glove box opening / closing control unit 55, the fuel lid opening / closing control unit 56, and the hood opening / closing control unit 57 are a glove box and a fuel lid (fuel replenishment) provided in the lower part of the instrument panel, respectively. Mouth) and bonnet (also called engine hood).

  The engine control unit 58 calculates the fuel injection amount and the ignition timing based on the accelerator opening, the intake air temperature, the engine coolant temperature, and the like, and controls the rotation of the engine.

  A functional operation control process executed at a predetermined timing in the ECU 10 of the in-vehicle device 1 will be described with reference to FIGS. 3 and 4. FIG. 3 shows a processing flow of this processing, and FIG. 4 shows a communication sequence between the in-vehicle device 1 and the portable devices 2 and 3.

  First, operation control information for prohibiting the operation of all functions is output to each of the above-described control units and devices via the communication I / F 10b (S11). At this point, even if the user performs an operation, each control unit and device does not operate.

Next, it is determined whether or not the first verification condition is satisfied using at least one of the following (S12).
-When the operation control information for prohibiting the operation of all functions is output, it is determined that the first verification condition is satisfied.
-It is determined that the first verification condition is satisfied when the verification is not correctly performed with any portable device.
-It determines with the 1st collation conditions having been satisfied, when predetermined time passes since collation (1st collation) was correctly performed between one portable machine. The previous verification is invalid.

  When it is determined that the first verification condition is not satisfied (S12: No), the process waits until the first verification condition is satisfied. This process may be terminated. On the other hand, when it is determined that the first verification condition is satisfied (S12: Yes), a search signal (also called a polling signal) for searching for a portable device (that is, requesting identification data for identifying the portable device). Is transmitted via the LF transmitter 11 (S13, Q11). The search signal may be transmitted constantly (at a predetermined timing) without setting the first verification condition.

  A response signal (that is, a first response signal: a response signal received first after transmitting a search signal) from any portable device (portable device 3 in the example of FIG. 4) via the UHF receiver 12. When received (S14: Yes, Q12), collation is performed based on the identification data included in the received response signal and the collation data associated with the portable device 3 stored in advance in the memory 10a of the ECU 10 (that is, the first 1 collation) is performed (S15).

  When the received identification data and the verification data are not correctly verified (S16: No), the process returns to step S13, and a search signal is transmitted. On the other hand, when the collation is correctly performed (S16: Yes, Q13), the operation control information indicating that the operation of the function is permitted to the control unit and the device included in the first function group (details will be described later), The data is output via the communication I / F 10b (S17, Q14).

  The control unit or device that has received the operation control information controls the operation of the actuator or the device in accordance with the content (operation permission or prohibition).

Next, it is determined using at least one of the following whether the second verification condition is satisfied (S18).
When the predetermined time has not elapsed after the first verification is correctly performed, it is determined that the second verification condition is satisfied. This corresponds to a configuration in which the collation unit performs the second collation when the second response signal is received within a predetermined time after the first collation is correctly performed.

-After 1st collation is correctly performed, when the door state detection part has not detected that the door of a vehicle was opened (or a user's boarding), it determines with 2nd collation conditions having been satisfied.
After the first collation is correctly performed, when the engine switch 15 (or a known ignition switch) is not turned on, it is determined that the second collation condition is satisfied.
These two conditions include vehicle state detection means for detecting the state of the vehicle, and the second verification condition is satisfied when the vehicle state becomes a predetermined state after the first verification is correctly performed. This corresponds to the configuration in which it is determined that the operation has been performed.

  When it is determined that the second verification condition is not satisfied (S18: No), this process ends. On the other hand, when it determines with the 2nd collation conditions having been satisfied (S18: Yes), the above-mentioned search signal is transmitted (S19, Q15).

  When a response signal (that is, the second response signal) is not received from the portable device (in the example of FIG. 4, other than the portable device 2, that is, the portable device 3 that has performed the first verification) (S20: No), step Return to S18. On the other hand, when a response signal is received from the portable device 2 (S20: Yes, Q16), it is determined whether the transmission area condition is satisfied by using at least one of the following (FIGS. 7 and 8). To do.

As shown in FIG. 7, when the transmission area when the first response signal is received is different from the transmission area when the second response signal is received, it is determined that the transmission area condition is satisfied. In the example of FIG. 7, although it is a combination of the vicinity of the driver's seat door (R1) and the vicinity of the passenger's seat door (R2), the combination of the transmission areas is a combination of any two of R1 to R5. Further, in which of the two transmission areas, the first verification may be determined in advance. For example, when it is set to perform the first verification in the vicinity of the driver's seat door (R1), even if there is a portable device in another communication area, the verification is not performed. Thereby, even if both portable devices are stolen, there is an effect that the operation of the second function group is not easily permitted. Furthermore, if the configuration is such that the functional operation control process is terminated when the second verification fails a predetermined number of times (for example, twice), the security can be further improved.

  In the example of FIG. 7, a plurality of predetermined different transmission areas are provided around the vehicle, and the in-vehicle device side transmission unit transmits the search signal in a predetermined order to the plurality of transmission areas. When the in-vehicle device side receiving unit receives a response signal from the portable device, the in-vehicle device side transmitting unit includes a transmission area specifying unit that specifies a transmission area to which the search signal is transmitted, and the collating unit outputs the second response signal. When the transmission area of the search signal when received is different from the transmission area of the search signal when receiving the first response signal, this corresponds to a configuration in which the second verification is performed.

As shown in FIG. 8, when the transmission area when the first response signal is received and the transmission area when the second response signal is received are the same, it is determined that the transmission area condition is satisfied. FIG. 8 illustrates the transmission area (R5) in the vicinity of the trunk (or back door). However, since two users can open the trunk lid only after they come close to the trunk, the trunk can be used in a cash transport vehicle or the like. Suitable for loading and unloading cash or valuables. Since there are five transmission areas, for example, if the transmission area used for verification is set to other than the vicinity of the driver's seat (R1), even if both portable devices are stolen, There is an effect that it is difficult to be permitted.

  In the example of FIG. 8, a plurality of predetermined different transmission areas are provided around the vehicle, and the in-vehicle device-side transmission unit transmits search signals in a predetermined order to the plurality of transmission areas. When the in-vehicle device side receiving unit receives a response signal from the portable device, the in-vehicle device side transmitting unit includes a transmission area specifying unit that specifies a transmission area to which the search signal is transmitted, and the collating unit outputs the second response signal. When the transmission area of the search signal when received is the same as the transmission area of the search signal when receiving the first response signal, this corresponds to a configuration in which the second verification is performed.

  Returning to FIG. 3, when it is determined that the transmission area condition is not satisfied (S21: No), the process returns to step S18. On the other hand, when it is determined that the transmission area condition is satisfied (S21: Yes), the identification data included in the previously received response signal is associated with the portable device 2 stored in advance in the memory 10a of the ECU 10. Collation (that is, second collation) is performed with the collation data (S22).

  Note that it is not necessary to determine whether or not the transmission area condition is satisfied. At this time, step S21 is not executed.

  When the received identification data and the verification data are not correctly verified (S23: No), the process returns to step S18. On the other hand, when the collation is correctly performed (S23: Yes, Q17), operation control information indicating that the operation of the function is permitted to the control unit and the device included in the second function group (details will be described later), The data is output via the communication I / F 10b (S24, Q18).

  The various functions illustrated in FIG. 2 do not operate when only the first verification is correctly performed, and the first function group that operates when the first verification is correctly performed. The second function group that operates when the two verifications are correctly performed is classified. Among these, the first function group includes a control unit and a device having a lower security level or lower privacy (for example, information that specifies an individual or information that includes personal preferences is not included). Moreover, you may make it include the minimum function required by driving | running | working of the vehicle 101. FIG. In the configuration of FIG. 2, the first function group includes engine start / stop control by operating the engine switch 15.

Further, the following functions may be included in the first function group.
Limiting the travel distance of the vehicle (controlled by the engine ECU 58): Start the engine, issue a warning when traveling a predetermined distance, and then stop the engine when the vehicle stops.
-Prohibit engine restart of vehicle (controlled by engine ECU 58): When the engine is started and the engine is stopped regardless of whether or not the vehicle is traveling (including idling stop), subsequent engine start is prohibited.

Limit the vehicle speed (controlled by the engine ECU 58): Limit the maximum vehicle speed to 40 km / h, for example.
Limiting the travel range of the vehicle (controlled by the navigation device 52 and the engine ECU 58): The travel range of the vehicle is, for example, within a radius of 1 km from the current position of the vehicle. Or, it is within the administrative area including the current position of the vehicle. When the travel range is exceeded, a warning is issued, and then the engine is stopped when the vehicle stops.

  Further, the second function group includes a control unit and a device having a higher security level or higher privacy than the first function group. 2 includes an audio device 51, a navigation device 52, an air conditioner control unit 53, a trunk opening / closing control unit 54, a glove box opening / closing control unit 55, a fuel lid opening / closing control unit 56, and a hood opening / closing control unit 57. The second function group may include the first function group.

  The second function group may include an in-vehicle terminal (operation) of an ETC (automatic toll collection) system.

In the above-described processing, the first verification is performed with the mobile device (2, 3) that has received the response signal first. That is, collation is performed in the order of response among two or more portable devices. This is because the collation unit is configured so that the first collation condition is satisfied when collation is not correctly performed with any portable device , or the first collation is correctly performed in the collation unit. This corresponds to a configuration in which the second verification condition is satisfied. Accordingly, the portable device may have the same configuration and does not require the changeover switch 24 of FIG. Also, when leaving a portable device to a hotel parking clerk, no matter which portable device you leave, you can only drive the vehicle 101 (you can not see inside the glove box or trunk), so you need to be careful about managing the portable device There is no.

  Apart from the above-described example, a portable device that performs the first verification and a portable device that performs the second verification may be determined in advance. That is, in FIG. 3, when the response signal transmitted from the portable device in response to the search signal transmitted when the first condition is satisfied is, for example, other than the portable device 3, is the first verification not satisfied? Do not perform the first verification.

  Moreover, it is good also as a structure which sets whether a 1st response signal and a 2nd response signal are transmitted in a portable machine (2 or 3) by the changeover switch 24. In this case, the appearance of the portable device may be different according to the response signal that can be transmitted. These correspond to a configuration in which a plurality of portable devices include only one that transmits only the first response signal and one that transmits only the second response signal. With this configuration, it is possible to further improve security by defining the collation order of portable devices.

  Hereinafter, the functional operation control process in the above configuration will be described with reference to FIGS. 5 and 6. Since this process is a modification of FIG. 3, the same step number is assigned to the same process as in FIG. 3, and the detailed description thereof is omitted here.

  After outputting the operation control information for prohibiting the operation of all functions (S11), when the first verification condition is satisfied (S12: Yes), the first search signal and the second search signal for searching for the portable device Is transmitted via the LF transmitter 11 (S131, Q31). Only the first search signal may be transmitted.

  The portable device 2 responds only to the first search signal. The portable device 3 responds only to the second search signal. When the first verification described later is not performed, the verification (second verification) is not performed even if the second response signal from the portable device 3 is received.

  When a response signal (that is, the first response signal) is received from the portable device 2 via the UHF receiver 12 (S141: Yes, Q32), the identification data included in the received response signal and the memory 10a of the ECU 10 Collation (that is, first collation) is performed with collation data stored in advance and associated with the portable device 2 (also referred to as a first portable device) (S151).

  When the received identification data and the verification data are not correctly verified (S161: No), the process returns to step S131, and the first and second search signals are transmitted. On the other hand, when the collation is correctly performed (S161: Yes, Q33), operation control information for permitting the operation of the function to the control unit and device included in the first function group is transmitted to the communication I / F 10b. (S17, Q34).

  Next, as in FIG. 3, it is determined whether or not the second verification condition is satisfied (S18). When it is determined that the second verification condition is not satisfied (S18: No), this process ends. On the other hand, when it is determined that the second verification condition is satisfied (S18: Yes), the transmission of the first search signal is stopped via the UHF transmission unit 11, and only the second search signal for searching for the portable device 3 is transmitted. (S191, Q35). This is because the in-vehicle device side transmission unit transmits the first search signal and the second search signal as search signals when the first verification condition is not satisfied, and the second search signal when the first verification condition is satisfied. It corresponds to the structure which transmits only.

  When the response signal (that is, the second response signal) from the portable device 3 is not received (S201: No), the process returns to step S18. On the other hand, when a response signal is received from the portable device 3 (S201: Yes, Q36), it is determined whether or not the transmission area condition is satisfied as in FIG.

  When it is determined that the transmission area condition is not satisfied (S21: No), the process returns to step S18. On the other hand, when it is determined that the transmission area condition is satisfied (S21: Yes), the identification data included in the previously received response signal and the mobile device 3 (second mobile phone) stored in advance in the memory 10a of the ECU 10 are stored. Collation (that is, second collation) is performed with the collation data associated with the data (also referred to as a machine) (S221).

  When the received identification data and the verification data are not correctly verified (S231: No), the process returns to step S18. On the other hand, when the collation is correctly performed (S231: Yes, Q37), the operation control information indicating that the operation of the function is permitted to the control unit and the device included in the second function group (details will be described later), The data is output via the communication I / F 10b (S24, Q38).

  Although the embodiments of the present invention have been described above, these are merely examples, and the present invention is not limited to these embodiments, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible.
