(Embodiment 1)
<Schematic configuration of vehicle system 1>
This embodiment will be described below with reference to the drawings. First, the vehicle system 1 will be explained using FIG. As shown in FIG. 1, the vehicle system 1 includes a smartphone (hereinafter referred to as smartphone) 2, a wearable terminal 3, and a vehicle-side unit 4. The vehicle system 1 is used in a vehicle. HV in FIG. 1 indicates a vehicle.

The smartphone 2 is a multifunctional mobile phone carried by the user. It is assumed that the smartphone 2 has at least a display function and a communication function. Note that "portable by the user" indicates that the user can carry and use the device. In other words, "being carried by the user" is not limited to a state in which the device is carried by the user, but also includes a state in which the device is not carried by the user. For example, this also includes a state in which the smartphone 2 is placed in the cabin of a vehicle in which the user of the smartphone 2 is riding.

The smartphone 2 provides notifications regarding various applications (hereinafter referred to as applications). It is assumed that the smartphone 2 is capable of sending notifications (hereinafter referred to as specific notifications) that the driver should not check while driving, as notifications regarding the application. For example, examples of specific notifications include the following. There is a notification of incoming emails in the email app. There is a notification of incoming messages in the Messages app. There are notifications for events in the calendar app. There are news notifications in the news app. Guidance notifications in the navigation app may not be included in specific notifications related to driving support. The specific notification itself does not necessarily need to be made by display, and may be made by sound, light, or the like. The display in the notification that the driver should not check while driving is a display for checking the content of the matter that the user is made aware of by the notification.

The wearable terminal 3 is a terminal worn and used by a user. It is assumed that the wearable terminal 3 has at least a display function and a communication function. The wearable terminal 3 may be configured to be communicatively connected to the smartphone 2 through a communication function and to cooperate with the smartphone 2. The wearable terminal 3 may cooperate with the smartphone 2 to provide a specific notification that can be performed by the smartphone 2. The wearable terminal 3 does not need to perform a display for confirming the content of the matter that the user is made aware of by the specific notification. This display may be configured to be performed by the smartphone 2 that cooperates with the wearable terminal 3. Note that a part of the content of this display may be simply displayed using the display function of the wearable terminal 3.

As the wearable terminal 3, various types that can be worn while driving a vehicle can be used. Examples include a watch type, wristband type, clip type, etc. In the following, a case will be described in which the wearable terminal 3 is a watch-type, wristband-type, or other device that is worn on the hand.

The vehicle-side unit 4 is used in a vehicle. The vehicle using the vehicle-side unit 4 will hereinafter be referred to as the own vehicle. The vehicle-side unit 4 is capable of communicating with the smartphone 2 and performing short-range wireless communication. The vehicle-side unit 4 performs authentication regarding permission to use the vehicle by checking the code via this short-range wireless communication. In the vehicle system 1, the smartphone 2 functions as an electronic key for the vehicle.

<Schematic configuration of smartphone 2>
Next, the smartphone 2 will be explained using FIG. 2. As shown in FIG. 2, the smartphone 2 includes a control unit 20, a communication module 21, a speaker 22, and a display device 23. In addition, in this embodiment, for the sake of convenience, explanations of the components of the smartphone 2 other than those related to the electronic key and the specific notification are omitted.

The communication module 21 is a communication module for performing short-range wireless communication by communicatively connecting with the vehicle-side unit 4 and the wearable terminal 3, which are registered in advance as communication connection partners. Short-range wireless communication is communication based on a predetermined short-range wireless communication standard, with a communication range of, for example, several tens of meters at most. As the short-range wireless communication standard, Bluetooth (registered trademark), Bluetooth Low Energy (hereinafter referred to as BLE), Wi-Fi (registered trademark), ZigBee (registered trademark), etc. can be adopted. For short-range wireless communication, high-frequency radio waves in a predetermined frequency band, such as radio waves in the 2.4 GHz band, are used. In the present embodiment, the following explanation will be given by taking as an example a case where the communication module 21 performs communication based on BLE in the 2.4 GHz band. The 2.4 GHz band is radio waves from 2400 MHz to 2500 MHz.

The communication module 21 periodically scans and receives advertising packets periodically transmitted from the vehicle-side unit 4, and establishes a connection (that is, a communication connection) with the vehicle-side unit 4. Information regarding authentication is sent and received through this connection, which is a virtual dedicated communication channel. As an example, the communication module 21 receives a request for a code for code verification from the vehicle-side unit 4. Furthermore, in response to this request, the communication module 21 causes the vehicle-side unit 4 to transmit a code for code verification on radio waves in the 2.4 GHz band.

Further, the communication module 21 performs short-range wireless communication by communicatively connecting with the wearable terminal 3 within the communication range. Near field communication between the communication module 21 and the wearable terminal 3 is used for cooperation between the smartphone 2 and the wearable terminal 3. In short-range wireless communication between the communication module 21 and the wearable terminal 3, information is also exchanged over radio waves in the 2.4 GHz band.

The speaker 22 outputs sound according to instructions from the control unit 20. As an example, when a specific notification is required due to execution of an application by the control unit 20, the speaker 22 provides a specific notification using sound. Note that the specific notification is not limited to a configuration in which it is performed by sound, but may be performed by vibration of a vibrator, light emission from a light emitting body such as an LED, or the like.

The display device 23 performs display according to instructions from the control unit 20. The display device 23 is, for example, a liquid crystal display. The display device 23 displays the content of the information provided by the application that prompts the user to confirm through a specific notification. An example is as follows. If the specific notification is a notification of an incoming email or message from an email app or message app, the content of the incoming email or message is displayed. If the specific notification is a notification of a schedule in a calendar app, the contents of this schedule are displayed. If the specific notification is a news notification from a news app, the content of this news is displayed.

The control unit 20 includes, for example, a processor, a memory, etc., and executes processing related to electronic keys and specific notifications. When the communication module 21 receives a code request transmitted from the vehicle-side unit 4, the control unit 20 outputs a code for code verification to the communication module 21. Thereby, this code is transmitted from the communication module 21 to the vehicle-side unit 4 on a radio wave in the 2.4 GHz band.

As an example, when a random number code is transmitted from the vehicle-side unit 4, the control unit 20 uses the random number code acquired via the communication module 21 as a secret key and an encryption algorithm used in the common key encryption method. Encrypt and generate encryption code. Then, this encrypted code may be output to the communication module 21 as a code for code verification. Note that the code for code verification may be a code distributed from a center or the like as the vehicle's regular key information.

In addition, the control unit 20 causes the communication module 21 to transmit information for coordinating the smartphone 2 and the wearable terminal 3 to the wearable terminal 3 that is connected for communication. For example, when an application on the smartphone 2 requires a specific notification, information for making the specific notification is sent from the communication module 21 to the wearable terminal 3 connected for communication. This causes the wearable terminal 3 to issue a specific notification.

Further, when the communication module 21 receives an instruction to prevent specific notification from being made (hereinafter referred to as a specific notification prohibition instruction) from the vehicle-side unit 4 that is communicatively connected to the communication module 21, the control unit 20 controls the specific notification. prevent this from happening. As a result, when the smartphone 2 is not linked to the wearable terminal 3, the smartphone 2 does not allow the smartphone 2 to issue a specific notification from its own device, thereby preventing the smartphone 2 from issuing a specific notification that should be made by the smartphone 2 itself. On the other hand, when the smartphone 2 is linked with the wearable terminal 3, the smartphone 2 does not allow the specific notification to be sent from the wearable terminal 3 that is communicatively connected to the communication module 21 by not allowing the specific notification to be sent from the own device. Don't let it happen.

Note that, when the own device is linked with the wearable terminal 3, the control unit 20 issues an instruction (from the vehicle-side unit 4 connected to the communication module 21 to cancel the communication connection with the wearable terminal 3). A configuration may also be adopted in which the communication connection with the wearable terminal 3 is canceled when the communication module 21 receives a connection cancellation instruction (hereinafter referred to as a connection cancellation instruction). As a result, when the smartphone 2 is linked with the wearable terminal 3, by canceling the communication connection with the wearable terminal 3, the smartphone 2 can receive a specific notification that is supposed to be sent from the wearable terminal 3 that is communicatively connected to the communication module 21. prevent this from happening.

When the control unit 20 prevents the own device or the wearable terminal 3 that is communicatively connected to the communication module 21 from issuing a specific notification, the control unit 20 issues a cancellation instruction from the vehicle-side unit 4 that is communicatively connected to the communication module 21, for example. The configuration may be such that the state in which the specific notification is not made continues until the communication module 21 receives the specific notification.

<Schematic configuration of wearable terminal 3>
Next, the wearable terminal 3 will be explained using FIG. 3. As shown in FIG. 3, the wearable terminal 3 includes a control section 30, a communication module 31, a speaker 32, and a display device 33. In addition, in this embodiment, for convenience, description of the components of the wearable terminal 3 other than those related to the specific notification is omitted.

The communication module 31 is a communication module for performing short-range wireless communication by communicatively connecting with the wearable terminal 3 registered in advance as a communication connection partner. As the short-range wireless communication, short-range wireless communication based on the same communication standard as the short-range wireless communication performed between the smartphone 2 and the vehicle-side unit 4 is used. That is, in the example of this embodiment, the communication module 31 performs communication based on BLE in the 2.4 GHz band. In this embodiment, the explanation will be given assuming that a communication connection between the smartphone 2 and the wearable terminal 3 used by the same user has been established in advance.

The speaker 32 outputs sound according to instructions from the control unit 30. As an example, when a specific notification is required due to cooperation between the smartphone 2 and the wearable terminal 3, the speaker 32 provides a specific notification using sound. Note that the specific notification is not limited to a configuration in which it is performed by sound, but may be performed by vibration of a vibrator, light emission from a light emitting body such as an LED, or the like.

The display device 33 performs display according to instructions from the control unit 30. The display device 33 is, for example, a liquid crystal display. The display device 33 may be configured to display simplified content (hereinafter referred to as simplified content) such as a heading of information provided by an application that prompts the user to confirm by a specific notification.

The control unit 30 includes, for example, a processor, a memory, etc., and executes processing related to specific notification. When the communication module 31 receives information for making a specific notification sent from the smartphone 2 that is in communication connection with the communication module 31, the control unit 30 uses the information, for example, from the speaker 32 to send a specific notification based on this information. Cause notification. The control unit 30 may cause the display device 33 to display the above-mentioned simplified content based on the information received by the communication module 31 for causing the specific notification to be made.

<Schematic configuration of vehicle side unit 4>
Next, an example of a schematic configuration of the vehicle-side unit 4 will be explained using FIG. 4. As shown in FIG. 4, the vehicle side unit 4 includes a verification ECU 40, a vehicle sensor 41, a locking/unlocking switch (hereinafter referred to as locking/unlocking SW) 42, a starting switch (hereinafter referred to as starting SW) 43, a smartphone key ECU 44, and a BLE module 45. , a body ECU 46, and a power unit ECU 47. For example, the verification ECU 40, vehicle sensor 41, body ECU 46, and power unit ECU 47 may be configured to be connected to the in-vehicle LAN.

The vehicle sensor 41 is a group of sensors for detecting various states of the own vehicle. As the vehicle sensor 41, there is a sensor for monitoring the occupants of the own vehicle. Examples of such sensors include an interior camera that captures an image of the interior of the own vehicle, and a seating sensor that detects the seating state of each seat. Further, as the vehicle sensor 41, there is a sensor for detecting the driving state, operation state, etc. of the own vehicle. Examples of such sensors include a vehicle speed sensor that detects the speed of the own vehicle, a shift position sensor that detects the shift position, and the like.

The locking/unlocking SW 42 is a switch for requesting locking/unlocking of vehicle doors such as a driver's seat door, a passenger's seat door, and a trunk room door. The locking/unlocking SW 42 may be provided on an outer door handle or a rear bumper of the vehicle. As the lock/unlock SW 42, for example, a touch switch or a mechanical button switch can be used. The signal from the locking/unlocking SW 42 may be configured to be output to the body ECU 46, for example.

The starting SW 43 is a switch for requesting starting of the driving source of the host vehicle. The starting SW 43 is provided, for example, in front of the driver's seat. As the starting SW 43, for example, a mechanical button switch can be used. The signal of the starting SW 43 may be configured to be output to the verification ECU 40, for example.

The smartphone key ECU 44 is an electronic control device including, for example, a processor, a memory, and the like. As shown in FIG. 4, the smartphone key ECU 44 includes a smartphone key control section 440 and a BLE communication section 441. The smartphone key ECU 44 executes processing related to a smartphone key system that uses the smartphone 2 as an electronic key. The smartphone key ECU 44 is connected to the verification ECU 40 and the BLE module 45.

The BLE communication unit 441 is a communication module including, for example, an IC, an antenna, a communication circuit, and the like. The BLE communication unit 441 performs BLE-compliant wireless communication according to instructions from the smartphone key control unit 440. The smartphone key control unit 440 includes, for example, a processor, a memory, etc., and controls communication in the BLE communication unit 441.

The smartphone key control unit 440 causes the BLE communication unit 441 to perform polling to periodically transmit advertising packets when the own vehicle is parked, according to instructions from the verification ECU 40. The smartphone key control unit 440 does not allow this polling to be performed if there is no instruction from the verification ECU 40. When this advertising packet can be acquired by the communication module 21 of the smartphone 2, a communication connection between the communication module 21 and the BLE communication unit 441 is established. After this communication connection is established, the smartphone key control unit 440 causes the BLE communication unit 441 to transmit a code for code verification to the smartphone 2. Also, when the start SW 43 is operated, the smartphone key control unit 440 receives an instruction from the verification ECU 40 and causes the BLE communication unit 441 to transmit a code for code verification to the smartphone 2.

Hereinafter, the case where a random number code is used as a code for code verification will be explained as an example. The smartphone 2 that has received the random number code transmitted from the BLE communication unit 441 transmits the encrypted code. The smartphone key control unit 440 acquires the encrypted code transmitted from the communication module 21 via the BLE communication unit 441 and outputs it to the verification ECU 40.

Note that when a plurality of users' smartphones 2 are brought into the own vehicle, a configuration may be adopted in which a communication connection is made between the communication module 21 of each user's smartphone 2 and the BLE communication unit 441. Hereinafter, when multiple users' smartphones 2 are brought into the own vehicle, a case will be described using as an example a case where communication connection is made between the communication module 21 of each user's smartphone 2 and the BLE communication unit 441.

The BLE module 45 is a communication module that can perform wireless communication based on BLE. Like the BLE communication unit 441, the BLE module 45 may have a configuration including, for example, an IC, an antenna, a communication circuit, and the like. This BLE module 45 corresponds to an antenna. Furthermore, the BLE module 45 may be configured to include, for example, an RSSI measurement circuit that measures the received signal strength (hereinafter referred to as RSSI) of received radio waves.

The BLE module 45 receives the radio waves and measures the RSSI by sniffing (that is, intercepting) the radio waves used for communication by establishing a communication connection between the communication module 21 and the BLE communication unit 441. . Further, the BLE module 45 receives the radio waves and measures the RSSI by sniffing (that is, intercepting) the radio waves used for communication by establishing a communication connection between the smartphone 2 and the wearable terminal 3. .

It is preferable that the BLE module 45 is installed at a plurality of locations inside and outside of the vehicle, for example, and measures the RSSI of the radio waves transmitted from the smartphone 2 or the wearable terminal 3 at each installation location. For example, the BLE module 45 is arranged, for example, on the outer surface of the vehicle door, the roof of the vehicle, the hood, the pillar, etc. so that a predetermined area outside the vehicle interior becomes a strong electric field area. Further, the BLE module 45 is disposed at the boundary between the center console and the instrument panel, the inner surface of the vehicle door, the trunk room, etc. so that a predetermined area within the vehicle interior becomes a strong electric field area.

As an example, as shown in FIG. 5, the BLE module 45 disposed outside the vehicle may include BLE modules 45a to 45f extending from the front to the rear of the left and right sides of the vehicle. Further, as an example, as shown in FIG. 5, as the BLE module 45 disposed in the vehicle interior, BLE modules 45g to 45j may be provided in the vehicle interior.

The BLE module 45a is arranged on the outer side of the right door of the front seat of the vehicle. The BLE module 45b is arranged on the outer surface of the right door of the rear seat of the vehicle. The BLE module 45c is arranged near the right corner of the rear end of the vehicle. The BLE module 45d is arranged on the outer side of the left door of the front seat of the vehicle. The BLE module 45e is arranged on the outer surface of the left door of the rear seat of the vehicle. The BLE module 45f is arranged near the left corner of the rear end of the vehicle.

The BLE module 45g is arranged at the boundary between the center console and the instrument panel of the vehicle. The BLE module 45h is arranged on the inner surface of the right door of the rear seat. The BLE module 45i is arranged on the floor of the trunk room. The BLE module 45j is arranged on the inner side of the left door of the rear seat of the vehicle.

The BLE module 45 outputs the measured RSSI to the smartphone key control unit 440. Since RSSI has a distance attenuation characteristic, it becomes possible to calculate the distance between the BLE module 45 and the smartphone 2 and wearable terminal 3 that are the transmission sources of radio waves from the RSSI measured by the BLE module 45. Further, from the distance between the BLE module 45 and the smartphone 2 and wearable terminal 3, it is possible to specify the position of the smartphone 2 and wearable terminal 3 with respect to the own vehicle.

For example, based on the distance calculated from each of the RSSIs measured by three or more BLE modules 45 and the placement positions of these BLE modules 45 in the own vehicle, the smartphone 2, The position of the wearable terminal 3 can be specified.

Note that although a configuration has been shown here in which the positions of the smartphone 2 and the wearable terminal 3 relative to the own vehicle are specified using RSSI, the present invention is not necessarily limited to this. For example, a configuration may be adopted in which the positions of the smartphone 2 and the wearable terminal 3 relative to the own vehicle are specified using an AoA (Angle of Arrival) method that performs localization using the arrival angle of radio waves. Alternatively, a configuration may be adopted in which the positions of the smartphone 2 and the wearable terminal 3 relative to the own vehicle are specified using a ToF (Time of Flight) method that performs localization using the flight time of radio waves.

The body ECU 46 is an electronic control device including, for example, a processor, a memory, and the like. The body ECU 46 locks and unlocks each vehicle door by outputting a drive signal for controlling locking and unlocking of each vehicle door to a door lock motor provided in each vehicle door. Further, a locking/unlocking SW 42 is connected to the body ECU 46, and a signal corresponding to whether the locking/unlocking SW 42 is turned on or off is inputted thereto.

The power unit ECU 47 is an electronic control device that controls a driving source such as an internal combustion engine or a motor generator of the vehicle. When the power unit ECU 47 obtains the start permission signal for the drive source from the verification ECU 40, it starts the drive source of the host vehicle.

The verification ECU 40 includes, for example, a processor, a memory, an I/O, and a bus connecting these, and executes various processes by executing a control program stored in the memory. The verification ECU 40 executes processing related to authentication in the own vehicle, processing related to restriction of specific notification in the own vehicle (hereinafter referred to as specific notification restriction related processing), and the like. Memory as used herein is a non-transitory tangible storage medium that non-temporarily stores computer-readable programs and data. Further, the non-transitional physical storage medium is realized by a semiconductor memory, a magnetic disk, or the like. This verification ECU 40 corresponds to an in-vehicle device. Note that details of the verification ECU 40 will be described below.

<Schematic configuration of verification ECU 40>
Here, an example of a schematic configuration of the verification ECU 40 will be described using FIG. 6. As shown in FIG. 6, the verification ECU 40 includes a vehicle state determination section 401, a communication processing section 402, a storage section 403, an authentication section 404, a position identification section 405, a permission section 406, an occupant determination section 407, an object identification section 408, and An instruction processing unit 409 is provided as a functional block. Note that some or all of the functions executed by the verification ECU 40 may be configured in hardware using one or more ICs. Further, some or all of the functional blocks included in the verification ECU 40 may be realized by a combination of software execution by a processor and hardware components.

The vehicle state determination unit 401 determines the state of the vehicle based on sensing results regarding the vehicle state detected by the vehicle sensor 41. For example, it is determined whether the vehicle is parked based on the vehicle speed detected by a vehicle speed sensor, the shift position detected by a shift position sensor, and the like.

The communication processing unit 402 cooperates with the smartphone key ECU 44 to transmit and receive data to and from the smartphone 2. The communication processing unit 402 requests the smartphone key ECU 44 to transmit an advertising packet in accordance with the signal input from the body ECU 46, the vehicle state determined by the vehicle state determination unit 401, and the like.

For example, the communication processing unit 402 requests the smartphone key ECU 44 to periodically transmit an advertising packet when the own vehicle is parked and after a certain period of time has elapsed since all the vehicle doors of the own vehicle have been locked. . In accordance with this request, the smartphone key ECU 44 causes the BLE communication unit 441 to perform polling to periodically transmit advertising packets. The communication processing unit 402 transmits a random number code to the smartphone 2 via the smartphone key ECU 44 when a communication connection is established with the smartphone 2 that has received the advertising packet. Then, the encrypted code sent from the smartphone 2 is acquired via the smartphone key ECU 44.

Further, the communication processing unit 402 may transmit a random number code to the smartphone 2 via the smartphone key ECU 44 even when the start SW 43 is operated. Then, the encrypted code transmitted from the smartphone 2 may be acquired via the smartphone key ECU 44. The fact that the starting SW 43 has been operated can be determined from the signal of the starting SW 43.

Further, the communication processing unit 402 acquires the RSSI of the radio waves used for transmitting the encrypted code, which are each measured by the BLE module 45, via the smartphone key ECU 44. The communication processing unit 402 acquires RSSI for each of the plurality of BLE modules 45 provided in the own vehicle. As an example, the BLE module 45 outside the vehicle may be used after the passenger gets off the vehicle until the passenger gets on the vehicle, and the BLE module 45 inside the vehicle may be used from after the passenger gets on the vehicle until the passenger gets off the vehicle. Whether the occupant gets out of the vehicle or gets on the vehicle may be determined based on the opening/closing of the vehicle door, the locked/unlocked state of the vehicle door, the seating state detected by a seating sensor, and the like.

Further, the communication processing unit 402 communicates between the smartphone 2 and the BLE communication unit 441 and/or between the smartphone 2 and the wearable terminal 3 at a predetermined timing such as when the driving source of the host vehicle is started after being permitted to start. What is necessary is to acquire the RSSI measured by the BLE module 45 during communication in the 2.4 GHz band between the two. For example, when multiple users' smartphones 2 are brought into the vehicle, the RSSI measured by the BLE module 45 during communication between the communication module 21 of each user's smartphone 2 and the BLE communication unit 441 may be acquired. . When multiple users' smartphones 2 and wearable terminals 3 are brought into the own vehicle, the BLE module is activated during communication between the communication module 21 of each user's smartphone 2 and the communication module 31 of the wearable terminal 3 with the BLE communication unit 441. What is necessary is to acquire the RSSI measured at 45. Note that the predetermined timing referred to here may be configured to be set at regular intervals after starting the travel drive source of the host vehicle.

The storage unit 403 stores information for authentication. The information for authentication is, for example, a secret key used in a common key cryptosystem. The storage unit 403 is, for example, an electrically rewritable nonvolatile memory.

Authentication unit 404 performs authentication by code comparison. The authentication unit 404 generates a code between the encryption code obtained by the communication processing unit 402 and the encryption code obtained by encrypting the random number code transmitted from the BLE communication unit 441 using the secret key stored in the storage unit 403. Perform verification. The result of the success or failure of the code matching is output to the permission unit 406.

The position specifying unit 405 intercepts and receives radio waves transmitted from the smartphone 2 and wearable terminal 3 by each of the plurality of BLE modules 45 installed in the own vehicle. Identify the location of terminal 3. As an example, the positions of the smartphone 2 and the wearable terminal 3 relative to the own vehicle are specified from the RSSI of radio waves intercepted by each of the plurality of BLE modules 45. Note that the position specifying unit 405 uses the AoA method, ToF method, etc., as described above, based on the reception results intercepted and received by each of the plurality of BLE modules 45, to locate the smartphone 2, The position of wearable terminal 3 may be specified.

For example, when the driving power source of the own vehicle starts, the position specifying unit 405 intercepts and receives radio waves transmitted from the smartphone 2 and wearable terminal 3 with each of the plurality of BLE modules 45 provided in the own vehicle. Based on the reception results, the positions of the smartphone 2 and the wearable terminal 3 in the cabin of the own vehicle can be specified.

For example, when the own vehicle is parked, the position specifying unit 405 intercepts and receives radio waves transmitted from the smartphone 2 by each of the plurality of BLE modules 45 installed in the own vehicle. Based on the reception result, All you have to do is identify the location of the smartphone 2 inside and outside the vehicle. Then, it is only necessary to specify whether the smartphone 2 is located inside or outside of the vehicle from the identified position of the smartphone 2.

In the present embodiment, the position specifying unit 405 locates the inside of the own vehicle based on the reception result of each of the plurality of BLE modules 45 receiving a 2.4 GHz band radio wave transmitted from the smartphone 2 serving as an electronic key. Identify the location of smartphone 2. In addition to this, the position specifying unit 405 intercepts and receives communication between the connected smartphone 2 and wearable terminal 3 using radio waves in the 2.4 GHz band using each of the plurality of BLE modules 45. Based on the reception results, the position of the wearable terminal 3 in the cabin of the own vehicle is specified.

For example, when the own vehicle is parked and locked, the permission unit 406 identifies the smartphone 2 used for verification by the position specifying unit 405 when the authentication unit 404 succeeds in verification and the smartphone 2 used for verification is located outside the vehicle. In this case, a signal may be sent to the body ECU 46 to permit unlocking of each vehicle door. This allows each vehicle door to be unlocked. On the other hand, even if the authentication unit 404 has successfully verified the verification, if the location identification unit 405 identifies that the smartphone 2 used for verification is not located outside the vehicle, the permission unit 406 determines whether the smartphone 2 is located outside the vehicle door or not. It is not necessary to send a signal to the body ECU 46 to permit unlocking. In this case, unlocking of each vehicle door is not permitted. The permission unit 406 does not send a signal to the body ECU 46 to permit unlocking of each vehicle door even if the verification by the authentication unit 404 is not successful. For example, the fact that the own vehicle is parked may be determined from the determination result by the vehicle state determination unit 401.

Further, the permission unit 406 causes the authentication unit 404 to complete the verification, and the location specifying unit 405 determines that the smartphone 2 used for the verification is located in the vehicle interior, for example, when the start switch is operated. In this case, a starting permission signal for the traveling drive source may be sent to the power unit ECU 47. As a result, the travel drive source of the host vehicle is started. On the other hand, even if the authentication unit 404 has successfully verified the verification, if the location identification unit 405 determines that the smartphone 2 used for verification is not located within the vehicle interior, the permission unit 406 determines whether the driving drive source It is sufficient if the start permission signal is not sent to the power unit ECU 47. In this case, the travel drive source of the host vehicle is not started. The permission unit 406 does not send a starting permission signal for the traveling drive source to the power unit ECU 47 even if the verification in the authentication unit 404 is not successful.

The occupant determination unit 407 determines whether anyone other than the driver is also riding in the own vehicle. The occupant determination unit 407 may determine whether anyone other than the driver is riding in the own vehicle based on the seating state of each seat detected by the seating sensor of the vehicle sensor 41, for example.

The target specifying unit 408 identifies a target (hereinafter referred to as an instruction target) to which an instruction regarding restriction of specific notification is to be sent. The target specifying unit 408 specifies the target according to the determination result by the occupant determining unit 407. For example, when the occupant determination unit 407 determines that there is someone other than the driver in the vehicle, the smartphone 2 located in the driver's seat of the vehicle or the wearable terminal 3 located in the driver's seat of the vehicle is connected for communication. It is sufficient to specify the smartphone 2 that is present as the instruction target. The positions of the smartphone 2 and the wearable terminal 3 in the cabin of the own vehicle may be specified by the position specifying unit 405. On the other hand, if the occupant determination unit 407 determines that no one other than the driver is in the vehicle (that is, only the driver), all smartphones 2 located in the cabin of the vehicle may be identified as the target of instruction. .

If the occupant determination unit 407 determines that there is someone other than the driver in the vehicle, the instruction processing unit 409 determines that the vehicle has started, and the position specifying unit 405 determines that the smartphone 2 or wearable When it is specified that the terminal 3 is located in the driver's seat, an instruction may be given to prevent the specific notification from being made on the smartphone 2 or wearable terminal 3 that has been identified as being located in the driver's seat. . This instruction may be configured to send the above-described specific notification prohibition instruction to the smartphone 2 specified as the instruction target by the target specifying unit 408. Furthermore, if the instruction target is the smartphone 2 that is communicatively connected to the wearable terminal 3 located in the driver's seat of the own vehicle, the above-mentioned connection release instruction may be sent to the smartphone 2.

Note that starting the vehicle may mean starting the travel drive source. In this case, the fact that the travel drive source has started can be identified by, for example, monitoring the power unit ECU 47 by the verification ECU 40. Alternatively, starting the own vehicle may mean that the own vehicle has started traveling. In this case, the verification ECU 40 may determine that the own vehicle has started traveling based on the vehicle speed detected by the vehicle speed sensor of the vehicle sensors 41.

According to the above configuration, even if the driver's smartphone 2 that is communicatively connected to the wearable terminal 3 worn by the driver is not in the driver's seat, the smartphone 2 that is communicatively connected to the wearable terminal 3 is used as the instruction target. Since an instruction to prevent specific notifications from being made is transmitted, it becomes possible to restrict specific notifications from the wearable terminal 3 worn by the driver.

Further, according to the above configuration, as shown in FIG. Even if they are mixed in the cabin of a car, it will be possible to send instructions to the driver's smartphone 2 to prevent specific notifications from being sent. Therefore, it is possible to prevent a decrease in convenience by restricting specific notifications from the smartphone 2 of users other than the driver. In the example of FIG. 7, a user sitting in the driver's seat A is wearing the wearable terminal 3, and the user's smartphone 2, which is communicatively connected to the wearable terminal 3, is placed in the passenger seat B. Furthermore, a user who is not wearing the wearable terminal 3 but is holding the smartphone 2 is seated in the rear seat C.

Furthermore, as shown in FIG. 8, even if a user other than the driver is also wearing the wearable terminal 3, the smartphone 2 connected to the wearable terminal 3 is not allowed to send specific notifications. Since no instructions are sent, it is possible to prevent a decrease in convenience by restricting specific notifications from the wearable terminal 3 of users other than the driver. In the example of FIG. 8, a user sitting in the driver's seat A is wearing the wearable terminal 3, and the user's smartphone 2, which is communicatively connected to the wearable terminal 3, is placed in the passenger seat B. Further, the user sitting in the rear seat C is also wearing the wearable terminal 3, and the user's smartphone 2, which is communicatively connected to the wearable terminal 3, is in a bag placed in the rear seat C.

On the other hand, when the occupant determining unit 407 determines that no one other than the driver is in the own vehicle, the instruction processing unit 409 sends a specific notification when the own vehicle starts, and the position specifying unit 405 determines the position. All the identified smartphones 2 may be instructed to prevent this from happening. It is more preferable that all the smartphones 2 whose positions have been identified by the position identification unit 405 referred to here refer to all the smartphones 2 whose positions have been identified within the cabin of the own vehicle.

The effects of the above configuration will be explained using FIG. 9. In the example of FIG. 9, the only occupant of the vehicle HV is the user of the driver's seat A (that is, the driver). Further, in the example of FIG. 9, the driver does not wear the wearable terminal 3, and the driver's smartphone 2 is placed on the passenger seat B. As in the example of FIG. 9, when the driver is the only occupant of the vehicle HV, even if the smartphone 2 is not located anywhere other than the driver's seat A, there is a very high possibility that this smartphone 2 is the driver's smartphone 2. Therefore, as shown in FIG. 9, even if the driver is not wearing the wearable terminal 3 and the smartphone 2 is placed in a place other than the driver's seat A, according to the above configuration, the driver's smartphone 2 is It becomes possible to send an instruction to the smartphone 2, which has a very high probability, to prevent specific notifications from being made.

In addition, the instruction processing unit 409 once transmits an instruction to the instruction target not to make a specific notification, and then sends an instruction to cancel this instruction at a predetermined timing while the own vehicle is not running. (hereinafter referred to as a restriction end instruction) may be configured to be transmitted. The predetermined timing may be when the vehicle is parked, when the starting switch 43 of the vehicle is turned off, or the like. According to this, when the user's vehicle is not running, the user's smartphone 2 or wearable terminal 3 can quickly transition to a state where specific notifications can be sent, and it is possible to receive specific notifications. become. Hereinafter, a case where the predetermined timing is when the starting SW 43 is turned off will be described as an example.

<Specific notification restriction related processing in verification ECU 40>
Next, an example of the flow of specific notification restriction related processing in the collation ECU 40 will be described using the flowchart of FIG. 10. The flowchart in FIG. 10 starts when the start SW 43 is turned on and the start of the driving force source of the own vehicle is permitted by verification with the smartphone 2 as an electronic key, and the driving force source of the own car starts. It is sufficient if the configuration is such that

First, in step S1, the occupant determination unit 407 determines whether anyone other than the driver is riding in the own vehicle. If it is determined that only the driver is in the vehicle (YES in S1), the process moves to step S2. On the other hand, if it is determined that there is someone other than the driver in the vehicle (NO in S1), the process moves to step S4.

In step S2, the position specifying unit 405 specifies the positions of the smartphone 2 and the wearable terminal 3 in the vehicle interior of the own vehicle based on the reception results intercepted and received by each of the plurality of BLE modules 45 in the vehicle interior. do. In step S3, the target specifying unit 408 specifies all the smartphones 2 that were specified as being located in the cabin of the own vehicle in S2 as instruction targets, and the process moves to step S6.

In step S4, similarly to S2, the position specifying unit 405 specifies the positions of the smartphone 2 and the wearable terminal 3 in the cabin of the own vehicle. In step S5, the target specifying unit 408 identifies the smartphone 2 that is communicatively connected to the smartphone 2 identified as being located in the driver's seat of the own vehicle in S4, or the wearable terminal 3 identified as being located in the driver's seat of the own vehicle in S4. It is specified as the instruction target, and the process moves to step S6.

In step S6, the instruction processing unit 409 transmits an instruction to prevent specific notification from being made to the instruction target specified in S3 or S5. When the smartphone 2 receives the instruction to prevent the specific notification from being made, the smartphone 2 disables the specific notification from being made. For example, if the smartphone 2 is identified as being located in the driver's seat, the smartphone 2 will not be allowed to issue a specific notification. In addition, if the smartphone 2 is connected to the wearable terminal 3 identified as being located in the driver's seat, the smartphone 2 can be prevented from making specific notifications or the communication connection can be canceled. This wearable terminal 3 is prevented from giving a specific notification.

In step S7, if it is the end timing of the specific notification restriction related process (YES in S7), the process moves to step S8. On the other hand, if it is not the end timing of the specific notification restriction related process (NO in S7), the process in S7 is repeated. The end timing of the specific notification restriction related process may be, for example, when the start SW 43 is turned off.

In step S8, the instruction processing unit 409 transmits a restriction termination instruction to the instruction target specified in S3 or S5. In the designated smartphone 2 that has received the restriction end instruction, the instruction to prevent specific notifications from being made is canceled, and it becomes possible to cause specific notifications to be made. Then, the specific notification restriction related process ends.

Note that in this embodiment, as an example, a configuration is shown in which the location of the smartphone 2 identified by the location identifying unit 405 is used for permission to control the vehicle, but the present invention is not necessarily limited to this. For example, the location of the smartphone 2 identified by the location identifying unit 405 may be used for other applications such as detecting that the smartphone 2 is trapped inside the vehicle when a passenger exits the vehicle and outputting a warning.

<Summary of Embodiment 1>
According to the configuration of the first embodiment, when the own vehicle is started and the position specifying unit 405 specifies that a mobile terminal such as the smartphone 2 or the wearable terminal 3 is located in the driver's seat, Since the instruction processing unit 409 issues an instruction to prevent specific notifications from being displayed on the mobile terminal, it becomes possible to limit the display to specific notifications that the driver should not check while driving. . Therefore, it becomes possible to limit the functions of the driver's mobile terminal that should be restricted while driving the vehicle while suppressing a decrease in the convenience of the mobile terminal. Further, the location of the mobile terminal in the driver's seat is determined by the position specifying unit 405 based on the reception result of each of the plurality of BLE modules 45 provided in the vehicle receiving radio waves transmitted from the mobile terminal carried by the user. This makes it possible to identify the driver's mobile terminal while reducing the user's effort. As a result, it is possible to distinguish the driver's mobile terminal while reducing the user's effort, and to restrict the functions of the driver's mobile terminal that should be restricted while driving the vehicle, while suppressing the decline in the convenience of the mobile terminal. becomes possible.

Further, according to the configuration of the first embodiment, the BLE module 45 that receives radio waves from the smartphone 2 during authentication for permission to control a vehicle via short-range wireless communication is used as a target for restricting specific notifications. It is also used to identify the location of the smartphone 2 and wearable terminal 3 in the vehicle interior. Therefore, compared to a configuration in which the BLE module 45 is provided in the vehicle only to specify the location of the smartphone 2 and wearable terminal 3 in the vehicle interior when specifying the target for restricting specific notifications, it is possible to eliminate waste. Become.

(Embodiment 2)
In the first embodiment, a configuration was shown in which the smartphone 2 also functions as an electronic key for the vehicle, but the present invention is not necessarily limited to this. For example, a configuration may be adopted in which the smartphone 2 does not function as an electronic key for the vehicle. In this case, the smartphone key ECU 44 and the BLE module 45 are not used for authentication for permission to control the vehicle via short-range wireless communication, but are used for the smartphone 2 and wearable terminal 3 when specifying the target for restricting specific notifications. What is necessary is just to adopt the structure used for specifying a position in a vehicle interior.

(Embodiment 3)
Although the first embodiment has been described using the smartphone 2 as an example of a mobile terminal that cooperates with the wearable terminal 3, the present invention is not necessarily limited to this. For example, the mobile terminal that cooperates with the wearable terminal 3 may be a mobile terminal other than the smartphone 2, such as a tablet terminal, as long as it can cooperate with the wearable terminal 3.

(Embodiment 4)
Although the above-described first embodiment shows a configuration in which the vehicle system 1 includes the wearable terminal 3, the present invention is not necessarily limited to this. For example, a configuration that does not include the wearable terminal 3 (hereinafter referred to as Embodiment 4) may be used. An example of Embodiment 4 will be described below using figures.

As shown in FIG. 11, the vehicle system 1a of the fourth embodiment is the same as that of the first embodiment except that it does not include the wearable terminal 3 and includes a vehicle-side unit 4a instead of the vehicle-side unit 4. This is the same as system 1. Further, the vehicle-side unit 4a is the same as the vehicle-side unit 4 of the first embodiment except that it includes a verification ECU 40a instead of the verification ECU 40.

Here, an example of a schematic configuration of the verification ECU 40a will be described using FIG. 12. As shown in FIG. 12, the verification ECU 40a includes a vehicle state determination unit 401, a communication processing unit 402a, a storage unit 403, an authentication unit 404, a position identification unit 405a, a permission unit 406, an occupant determination unit 407, an object identification unit 408a, and An instruction processing unit 409a is provided as a functional block. The verification ECU 40a includes a communication processing unit 402a, a position specification unit 405a, a target specification unit 408a, and an instruction processing unit 409a instead of the communication processing unit 402, the position specification unit 405, the target specification unit 408, and the instruction processing unit 409. Except for this point, it is the same as the verification ECU 40 of the first embodiment. This verification ECU 40a also corresponds to an in-vehicle device.

Since the wearable terminal 3 is not included in the vehicle system 1a, the communication processing unit 402a does not acquire the RSSI measured by the BLE module 45 during communication between the smartphone 2 and the wearable terminal 3. Except for this point, the communication processing unit 402a is similar to the communication processing unit 402 of the first embodiment.

The position specifying unit 405a does not specify the position of the wearable terminal 3 because the vehicle system 1a does not include the wearable terminal 3. Except for this point, the position specifying unit 405a is similar to the position specifying unit 405 of the first embodiment.

Since the vehicle system 1a does not include the wearable terminal 3, the target specifying unit 408a does not specify the smartphone 2 that is communicatively connected to the wearable terminal 3 as the instruction target. Except for this point, the target specifying unit 408a is similar to the target specifying unit 408 of the first embodiment.

Since the vehicle system 1a does not include the wearable terminal 3, the instruction processing unit 409a does not issue an instruction to the smartphone 2 that is communicatively connected to the wearable terminal 3. Except for this point, the instruction processing section 409a is similar to the instruction processing section 409 of the first embodiment.

For example, when the occupant determination unit 407 determines that someone other than the driver is in the vehicle, the instruction processing unit 409a determines that the vehicle has started and the position specifying unit 405a detects the smartphone 2. When it is specified that the smartphone 2 is located in the driver's seat, an instruction may be given to prevent the specific notification from being made by the smartphone 2 that has been identified as being located in the driver's seat. This instruction may be configured to send the above-described specific notification prohibition instruction to the smartphone 2 specified as the instruction target by the target specifying unit 408.

According to the above configuration, as shown in FIG. 11, the smartphone 2 of the user sitting in the driver's seat A (that is, the driver) and the smartphone 2 of a user other than the driver sitting in the passenger seat B are connected to each other in the vehicle. Even if they are mixed in the vehicle, it will be possible to send instructions to the driver's smartphone 2 to prevent specific notifications from being sent. Therefore, it is possible to prevent a decrease in convenience by restricting specific notifications from the smartphone 2 of users other than the driver. In the example of FIG. 11, the smartphone 2 of the user sitting in the driver's seat A is placed in the driver's seat A, for example, in the user's pocket. Further, the smartphone 2 of the user sitting in the passenger seat B is located in the passenger seat B, for example, held in the user's hand.

On the other hand, for example, when the occupant determination unit 407 determines that no one other than the driver is in the vehicle, the instruction processing unit 409a sends a specific notification to the position determination unit 405 when the vehicle starts. What is necessary is to instruct all the identified smartphones 2 to prevent this from happening. It is more preferable that all the smartphones 2 whose positions have been identified by the position identification unit 405 referred to here refer to all the smartphones 2 whose positions have been identified within the cabin of the own vehicle.

The effects of the above configuration will be explained using FIG. 13. In the example of FIG. 13, the only occupant of the vehicle HV is the user of the driver's seat A (that is, the driver). Further, in the example of FIG. 13, the driver's smartphone 2 is placed on the passenger seat B. As in the example of FIG. 13, when the driver is the only occupant of the vehicle HV, even if the smartphone 2 is not located anywhere other than the driver's seat A, there is a very high possibility that this smartphone 2 is the driver's smartphone 2. Therefore, as shown in FIG. 13, even if the driver places the smartphone 2 in a place other than the driver's seat A, according to the above configuration, the smartphone 2, which is highly likely to be the driver's smartphone 2, is designated. It becomes possible to send instructions to prevent specific notifications from being made.

Even with the configuration of Embodiment 4, it is possible to prevent specific notifications from being sent to the driver's smartphone 2. Therefore, similarly to Embodiment 1, the driver's smartphone 2 can be prevented from receiving specific notifications. This makes it possible to distinguish among the mobile terminals of the driver and restrict the functions of the driver's mobile terminal that should be restricted while driving the vehicle, while suppressing a decrease in the convenience of the mobile terminal.

(Embodiment 5)
Although the first embodiment shows a configuration in which the wearable terminal 3 does not establish a communication connection with the vehicle-side unit 4, the present invention is not necessarily limited to this. For example, the wearable terminal 3 may be configured to be communicatively connectable to the vehicle-side unit 4. In this case, a configuration may be adopted in which the smartphone 2 of Embodiment 4 is replaced with the wearable terminal 3.

(Embodiment 6)
In Embodiment 1 and Embodiment 4, a configuration was shown in which the occupant determination unit 407 switches the processing of the instruction processing units 409 and 409a depending on whether or not someone other than the driver is riding in the own vehicle, but the invention is not necessarily limited to this. For example, the verification ECUs 40 and 40a may not include the occupant determination section 407, and the processing of the instruction processing sections 409 and 409a may not be switched depending on whether or not someone other than the driver is in the vehicle.

In this case, for example, the instruction processing units 409 and 409a detect that the own vehicle is started and that the mobile terminals such as the smartphone 2 and the wearable terminal 3 are located in the driver's seat using the position specifying units 405 and 405a. If a specific notification is specified, the configuration may be such that an instruction is given to prevent the specific notification from being made on that mobile terminal.

(Embodiment 7)
In Embodiment 1 and Embodiment 4, a configuration was shown in which the collation ECUs 40 and 40a, which also perform authentication to permit control of the vehicle, also perform processing related to specific notification, but this is not necessarily the case. For example, a configuration may be adopted in which an ECU other than the ECU that performs authentication to permit control of the vehicle performs processing related to the specific notification. In this case, this ECU other than the ECU that performs authentication to permit control of the vehicle corresponds to the in-vehicle device.
