  In FIG. 1, for example, an in-vehicle device 10 accepts an operation input of a passenger (driver or passenger) boarding a vehicle and performs predetermined functions (navigation function, audio function, image reproduction function, communication function) according to the operation. Etc.). However, the configuration of the in-vehicle device 10 according to the present embodiment is not limited to the AVN device. A navigation device that provides a navigation function in response to an operation input by a passenger on the vehicle, an audio device that provides an audio function, a playback function of information recorded on a CD (Compact Disc), a DVD (Digital Versatile Disc), or the like Any vehicle-mounted device may be used. The in-vehicle device 10 is connected to various ECUs (Electronic Control Units) mounted in the vehicle via an in-vehicle network such as a CAN (Controller Area Network). In the in-vehicle device 10, various information indicating the state of the vehicle detected by the sensor 113 is acquired via various ECUs connected to the in-vehicle network. For example, the in-vehicle device 10 acquires information such as the position of the ignition switch, the shift lever position, the on / off of the parking brake, and the vehicle speed via various ECUs.

The information processing terminal 20 is a small portable computer such as a smartphone, a mobile phone, a tablet terminal, a personal information terminal, or a wearable computer (smart watch or the like). The information processing terminal 20 includes, for example, a display device such as an LCD (Liquid Crystal Display), an EL (Electroluminescence) panel, and an organic EL panel, and an output device such as a speaker. The information processing terminal 20 includes an input device such as a touch panel, a push button, and a microphone. In the in-vehicle system 1 of FIG. 1, the information processing terminal 20 is loaded with an application program that cooperates with the in-vehicle device 10 and performs operation support for using a predetermined function such as a navigation function provided by the in-vehicle device. The application program installed in the information processing terminal 20 is an example of a “cooperation program”.

  For example, when the in-vehicle device 10 having a navigation function cooperates, map information including the current position (latitude, longitude), destination, landmark, etc. of the host vehicle is displayed on the display device of the information processing terminal 20 by executing the application. Is displayed. Similarly, in the case of the vehicle-mounted device 10 having an audio function, for example, channel information for viewing TV broadcasts, radio broadcasts, and the like, a music list to be reproduced, a video list, and the like are displayed on the display device of the information processing terminal 20 or the like.

Then, when the host vehicle is traveling, the in-vehicle device 10 regulates display and operation for using a predetermined function provided by the in-vehicle device. In the in-vehicle system 1, when the host vehicle is traveling, the operation support to the in-vehicle device 10 via the information processing terminal 20 is also restricted.

As an example of display regulation and operation regulation in the in-vehicle system 1, a mode in which the on / off of the parking brake detected by the sensor 113 and the vehicle speed are combined will be described. Note that the travel regulation described in (1) to (3) below is an example in which regulation is performed at three levels according to the state of the vehicle.
(1) Regulation level 1
At the restriction level 1, the in-vehicle device 10 detects an on state of the parking brake. The in-vehicle system 1 accepts an operation input to the in-vehicle device 10 via the operation unit 104 and an operation input via the cooperating information processing terminal 20 on condition that the parking brake is on. The in-vehicle device 10 displays various information for providing a predetermined function via the display unit 105.
(2) Regulation level 2
At the restriction level 2, the in-vehicle device 10 detects the parking brake off state. The in-vehicle system 1 regulates images displayed on the display unit 105 and the information processing terminal 20 on the condition that the parking brake is off. For example, the in-vehicle system 1 limits the video displayed on the in-vehicle device 10 and the information processing terminal 20 to the provision of the navigation function. In the in-vehicle system 1 at the restriction level 2, the operation input indicating the destination is permitted, the route search from the current location to the destination is permitted, the display of the map information including the landmark, and the like are performed.
(3) Regulation level 3
At the regulation level 3, the in-vehicle device 10 detects the parking brake off state and also detects that the vehicle speed of the vehicle exceeds a predetermined value (for example, 0 km / h). The in-vehicle system 1 is configured to perform basic operations (push button operation, information input, operation menu, etc.) to the in-vehicle device 10 via the operation unit 104 on condition that the parking brake is off and the vehicle speed exceeds a predetermined value. Call operation etc.) is prohibited. Further, the in-vehicle system 1 restricts the cooperative operation via the information processing terminal 20 from being prohibited. However, the transition operation of the navigation screen displayed on the display unit 105 of the in-vehicle device 10 with the movement of the vehicle is permitted.

  The in-vehicle system 1 according to the present embodiment includes NFC (Near Field Communication) modules (114 # 1 to 114 # n) that perform short-range wireless communication with the information processing terminal 20 that cooperates with the in-vehicle device 10.

Moreover, the vehicle equipment 10 acquires apparatus information from the information processing terminal 20 which cooperates with the said vehicle equipment via the communication module 111 by execution of an application. And the vehicle-mounted system 1 which concerns on this embodiment was acquired via the communication module 111 and the apparatus information of the information processing terminal 20 acquired via each NFC module (114 # 1-114 # n). Based on the device information, the information processing terminal 20 operated in cooperation with the in-vehicle device 10 in the traveling vehicle is authenticated.

  The installation location of the NFC module (114 # 1 to 114 # n) in the vehicle is fixed for each seat, for example, in the vicinity of the seat on which the driver or passenger sits. Here, the communication range of the NFC module (114 # 1 to 114 # n) is limited depending on the distance to the counterpart device that can communicate via the module. For this reason, the information processing terminal 20 authenticated through the NFC module (114 # 1 to 114 # n) can be associated with at least a passenger seated at the seat position where the NFC module is installed. That is, the driver | operator of the information processing terminal 20 who performed the authentication act via NFC module (114 # 1-114 # n) in the vehicle currently drive | working by the authentication with respect to the information processing terminal 20 is the driving | operation which sits in a driver's seat It is possible to identify whether the passenger is a passenger or a passenger seated in the passenger seat or the rear seat.

  The installation location of the NFC modules (114 # 1 to 114 # n) in the vehicle may be limited to the passenger seat and the rear seat other than the driver seat. In such a form, at least the information processing terminal 20 authenticated during traveling through the NFC modules (114 # 1 to 114 # n) is a passenger (other than the driver) sitting in the passenger seat or the rear seat. It is possible to specify that the information processing terminal 20 is operated by the passenger.

  When the information processing terminal 20 authenticated during traveling is the information processing terminal 20 operated by a passenger other than the driver, the in-vehicle system 1 of the present embodiment does not perform operation restriction or display restriction, and does not perform the information restriction. An operation input via the terminal 20 is accepted. As a result, the in-vehicle system 1 can release the restriction on the passenger's operation input during traveling and can provide a predetermined function of the in-vehicle device 10 according to the operation input. For example, the in-vehicle device 10 accepts a setting operation for a navigation function such as a destination change. According to the in-vehicle system 1 of the present embodiment, it is possible to operate the in-vehicle device 10 by a passenger other than the driver even during traveling.

The NFC module 114 is a communication module that performs short-range wireless communication using a frequency of 13.56 MHz compliant with ISO (International Organization for Standardization) / IEC (International Electrotechnical Commission) standards (for example, ISO / IEC 1443). . The NFC module 114 is provided for each seat in the vicinity of a seat on which a driver or a passenger in the vehicle on which the vehicle-mounted device 10 is mounted. The NFC module 114 is an example of “first communication means”.

  FIG. 2 is a diagram for explaining an arrangement position of the NFC module 114 in the vehicle. In FIG. 2, the form which has arrange | positioned the NFC module 114 to each of the front passenger seat and rear seat which passengers other than a driver | operator sit down is illustrated. In FIG. 2, a driver 1 </ b> A driving a vehicle 2 equipped with the vehicle-mounted device 10 is seated on a driver seat 2 a that faces the steering wheel that steers the vehicle 2. The passenger 1B of the vehicle 2 is seated on the passenger seat 2b or the rear seat 2c. The in-vehicle device 10 is provided in the center console so that, for example, a driver 1A or a passenger 1B sitting on the passenger seat 2b can easily view information displayed on the operation component of the operation unit 104 or the display device of the display unit 105. .

  As shown in FIG. 2, the NFC module 114 # 1 is in the vicinity of the passenger seat 2b, the NFC module 114 # 2 is in the rear seat 2c on the driver's seat 2a side, and the NFC module 114 # is in the rear seat 2c on the passenger seat 2b side. 3 is arranged. The communication range of the NFC module 114 is limited depending on the distance to the counterpart device that communicates via the module. For this reason, as shown in FIG. 2, by providing the NFC module 114 with a fixed arrangement position for each seat on which a passenger is seated, the existence range of counterpart devices that can communicate via the NFC module during traveling Can be limited to a predetermined range (for example, a distance range of about 10 cm from the NFC module). In the example of FIG. 2, for example, it is possible to limit the partner device that can communicate with the NFC module 114 # 1 during traveling to the information processing terminal 20 operated by the passenger 1B seated in the passenger seat 2b. Similarly, the partner device that can communicate with the NFC module 114 # 2 can be limited to the information processing terminal 20 operated by the passenger sitting on the rear seat 2c on the driver's seat 2a side. In addition, the counterpart device that can communicate with the NFC module 114 # 3 can be limited to the information processing terminal 20 operated by the passenger sitting on the rear seat 2c on the passenger seat 2b side.

In the present embodiment, reading of device information of the information processing terminal 20 operated by the passenger is performed via the NFC module 114. And the vehicle equipment 10 authenticates the information processing terminal 20 that cooperates via the communication module 111 during traveling based on the device information acquired from the information processing terminal 20. In the in-vehicle device 10, for example, the device information of the information processing terminal 20 authenticated through the NFC module 114 matches the device information acquired from the information processing terminal 20 that cooperates through the communication module 111 during traveling. In this case, even when the vehicle is traveling, an operation input from the passenger via the information processing terminal is accepted.

[3. Process flow
Next, processing relating to operation restriction of the in-vehicle system 1 according to the present embodiment will be described with reference to the drawings of FIGS. FIG. 3 is a flowchart illustrating an example of an operation restriction process using NFC authentication of the in-vehicle device 10. As described with reference to FIG. 2, the NFC module 114 is fixedly provided for each seat on which a passenger is seated in a vehicle on which the vehicle-mounted device 10 is mounted. In addition, the information processing terminal 20 is loaded with an application program that performs operation support for using a predetermined function provided by the in-vehicle device 10.

  In the flowchart of FIG. 3, the start of the process is exemplified when communication is established with the information processing terminal 20 that cooperates with the in-vehicle device 10 in the vehicle in which the driving operation is performed through the execution of the application. . The in-vehicle device 10 and the information processing terminal 20 establish a communication connection in accordance with a communication standard such as USB or Bluetooth. The in-vehicle device 10 acquires device information (MAC address or the like) for authentication via the NFC module 114 from the information processing terminal 20 that executes the application (S1). The in-vehicle device 10 temporarily stores the acquired device information in a predetermined area of the main storage unit 102.

  After the communication connection with the information processing terminal 20 is established, the in-vehicle device 10 executes a cooperation process for using a predetermined function provided by the in-vehicle device. In addition, the in-vehicle device 10 sets a cooperation flag indicating that the own apparatus is in the cooperation processing with the start of the cooperation processing (S2). The cooperation flag is, for example, binary status information indicating whether or not the own apparatus is performing a cooperation process. The in-vehicle device 10 temporarily stores the set cooperation flag in a predetermined area of the main storage unit 102 in association with the time information. The in-vehicle device 10 proceeds to the process of S3 and executes the processes shown from S3 to S10. Note that the process illustrated in FIG. 3 ends when the cooperation operation of the information processing terminal 20 ends.

In the in-vehicle device 10 during the cooperation process, for example, an operation input of a passenger operating the information processing terminal 20 is accepted via the communication module 111. The in-vehicle device 10 responds to the received operation input with map information including the current position (latitude, longitude), destination, landmark, etc. of the own vehicle, channel information for viewing TV broadcasts, radio broadcasts, etc., and playback targets Various information such as music list and video list. Various information provided from the in-vehicle device 10 is displayed on the display device of the information processing terminal 20 on which the application is executed.

  In the process of S4, the in-vehicle device 10 detects a change in the traveling state of the host vehicle based on the detection signal of the sensor 113. A change in the running state of the host vehicle is detected via an ECU connected to the in-vehicle network. The vehicle-mounted device 10 obtains various information (ignition switch position, shift lever position, parking brake on / off, vehicle speed, etc.) indicating the current vehicle state in response to detection of a change in the running state of the host vehicle. . The in-vehicle device 10 temporarily stores the acquired information indicating the state of the vehicle in a predetermined area of the main storage unit 102, and proceeds to the process of S5.

  In the process of S5, as will be described later, an authentication process is performed based on the device information of the information processing terminal 20 acquired via the NFC module 114 provided fixed for each seat. For example, the information processing terminal 20 operated by the passenger sitting in the passenger seat is authenticated via the NFC module 114 fixedly provided in the vicinity of the passenger seat. Similarly, the information processing terminal 20 operated by the passenger seated in the rear seat 2c on the driver's seat 2a side is authenticated via the NFC module 114 fixedly provided near the rear seat 2c on the driver's seat side. . Further, the information processing terminal 20 operated by the passenger sitting on the rear seat 2c on the passenger seat 2b is authenticated through the NFC module 114 fixedly provided in the vicinity of the rear seat 2c on the passenger seat 2b side. Here, the process of S <b> 5 executed by the in-vehicle device 10 is an example of a “specifying unit”.

  In the process of S6, based on the authentication result of S5, it is determined whether or not the information processing terminal 20 operated by the passenger sitting in a seat other than the driver's seat is authenticated. Whether the information processing terminal 20 is authenticated is determined based on whether the authentication flag is in an active state, as will be described later. If the device information of the information processing terminal 20 acquired via the NFC module 114 satisfies a predetermined authentication condition (S6, “Yes”), the in-vehicle device 10 determines that NFC authentication has been performed, and S9 Move on to processing. On the other hand, when the device information of the information processing terminal 20 acquired through the NFC module 114 does not satisfy the predetermined authentication condition (S6, “No”), the in-vehicle device 10 determines that the NFC authentication is not performed. , The process proceeds to S7.

  In the process of S7, the in-vehicle device 10 determines whether or not the host vehicle is stopped. For example, when the vehicle speed detected by the sensor 113 is “0 km / h” in various information indicating the state of the vehicle acquired in the process of S5 (S7, “Yes”), the in-vehicle device 10 is the host vehicle. Is determined to be stopped, and the process proceeds to S9. On the other hand, when the vehicle speed similarly detected by the sensor 113 is not “0 km / h” (S7, “No”), the in-vehicle device 10 determines that the state of the own vehicle is not stopped, and the process of S8 Migrate to In the process of S7, the in-vehicle device 10 may determine whether or not the vehicle is stopped by combining information such as the shift lever position, parking brake and brake on / off information, and the vehicle speed.

  In the process of S <b> 8, the in-vehicle device 10 notifies the information processing terminal 20 that cooperates via the communication module 111 that the operation is being restricted (operation restriction is on). As will be described later with reference to FIG. 6, the information processing terminal 20 to be linked receives a notification that the operation is being restricted, and the linkage operation for using the predetermined function provided by the in-vehicle device 10 is prohibited. .

  In the process of S <b> 9, the in-vehicle device 10 notifies the information processing terminal 20 that cooperates via the communication module 111 that the operation restriction is released (operation restriction is turned off). As will be described later with reference to FIG. 6, the cooperative information processing terminal 20 receives a notification to the effect that the operation restriction is released, and permits a cooperative operation for using a predetermined function provided by the in-vehicle device 10.

Next, FIG. 4 will be described. FIG. 4 is a flowchart showing an example of the detailed processing in S5. In the flowchart of FIG. 4, the in-vehicle device 10 acquires device information of the information processing terminal 20 on which the application has been executed via the NFC module 114 that is fixed for each seat (S11). For example, a passenger sitting in the passenger seat 2b brings the information processing terminal 20 operated by the passenger close to the NFC module 114 provided in the vicinity of the passenger seat in order to use a predetermined function provided by the in-vehicle device 10. And device information of the information processing terminal 20 is acquired. Similarly, a passenger sitting on the driver seat side rear seat 2c brings the information processing terminal 20 operated by the passenger closer to the NFC module 114 provided in the vicinity of the driver seat side rear seat 2c. Device information of the information processing terminal 20 is acquired. Further, the passenger sitting on the rear seat 2c on the passenger seat side brings the information processing terminal 20 operated by the passenger close to the NFC module 114 provided on the rear seat 2c on the passenger seat side. 20 pieces of device information are acquired.

  In the process of S12, the in-vehicle device 10 determines whether or not the device information acquired via the NFC module 114 satisfies the authentication condition. Specifically, when the device information acquired from the information processing terminal 20 that cooperates with the vehicle-mounted device 10 matches the device information acquired via the NFC module 114 provided near each seat, the authentication condition is satisfied. to decide. When the authentication condition is satisfied, a passenger who operates the information processing terminal 20 can be specified. For example, when the device information of the information processing terminal 20 connected via the communication module 111 matches the device information acquired via the NFC module provided near the passenger seat, the operation of the information processing terminal 20 is performed. Can be identified as a passenger sitting in the passenger seat. This is because the communication range of the NFC module 114 is limited depending on the relative distance to the information processing terminal 20. The same applies to passengers sitting on the rear seat 2c.

  When the installation location of the NFC module 114 fixedly provided for each seat includes the driver's seat 2a, the in-vehicle device 10 acquires the identification number assigned to the NFC module 114 in the processing of S11. May be. And in the process of S12, based on the acquired identification number, you may make it discriminate | determine a passenger other than a driver and a driver. That is, as the authentication condition of the process of S12, the acquired NFC module 114 identification number indicates the NFC module 114 provided near the seat other than the driver's seat, and the device information acquired via the NFC module 114, What is necessary is just to determine with satisfy | filling authentication conditions, when the apparatus information of the information processing terminal 20 connected via the communication module 111 corresponds.

  When the in-vehicle device 10 determines that the device information acquired via the NFC module 114 fixedly provided near each seat satisfies the authentication condition (S12, “Yes”), the in-vehicle device 10 proceeds to the processing of S13. . On the other hand, when the in-vehicle device 10 determines that the device information acquired via the NFC module 114 fixedly provided near each seat does not satisfy the authentication condition (S12, “No”), FIG. The process proceeds to S7 shown.

  In the process of S <b> 13, the in-vehicle device 10 sets an authentication flag indicating that the information processing terminal 20 during the cooperation process is authenticated to an active state. The authentication flag is, for example, binary status information indicating whether or not the information processing terminal 20 during the cooperation process is in an authentication state (active state) or not (inactive state). The in-vehicle device 10 temporarily stores the authentication flag set in the active state in a predetermined area of the main storage unit 102 in association with the time information. In the process of S6 shown in FIG. 3, the active state of the authentication flag is determined.

In the process of S14, the in-vehicle device 10 sets a re-authentication timer for re-authenticating the information processing terminal 20 during the cooperation process using the NFC module 114 fixedly provided in the vicinity of the seat where the passenger is seated. To do. The set value of the re-authentication timer can be set arbitrarily. However, it is desirable to set the timer value in minutes from the viewpoint of ensuring safety during traveling. That is, it is preferable that the authentication action is performed at regular intervals so that the operation input to the in-vehicle device 10 via the authenticated information processing terminal 20 is not continued for a long period of time. The in-vehicle device 10 can suppress, for example, lending the authenticated information processing terminal 20 to a person other than the passenger by setting the re-authentication timer. After the process of S14, the process proceeds to S9 shown in FIG.

  Next, FIG. 5 will be described. FIG. 5 is a flowchart illustrating an example of timer processing. In the flowchart of FIG. 5, the start of the process is exemplified when the re-authentication timer is set. The in-vehicle device 10 measures the elapsed time with respect to the timer value set by the re-authentication timer, and detects a timeout (S21). If the in-vehicle device 10 does not detect a timeout (S21, “No”), the in-vehicle device 10 continues to measure the passage of time. On the other hand, when the time-out is detected (S21, “Yes”), the in-vehicle device 10 proceeds to the process of S22.

  In the process of S22, the in-vehicle device 10 resets the status value of the authentication flag to the non-authenticated state. By the process of S22, the authentication flag set to the active state in the process of S13 of FIG. 4 is reset to the inactive state. In the non-authenticated state, it is determined that the vehicle is not authenticated (S6, “No”) in the process of S6 in FIG. 3, and therefore the passenger's operation via the information processing terminal 20 is performed again in the traveling vehicle. Regulations and labeling regulations are implemented. In the in-vehicle device 10, an unnecessary operation via the information processing terminal 20 can be suppressed by providing a restriction on the operation period for the passenger by the timer function. The in-vehicle device 10 associates the time information with the reset authentication flag and temporarily stores it in a predetermined area of the main storage unit 102. After the process of S22, the process of FIG.

  Next, FIG. 6 will be described. FIG. 6 is a flowchart illustrating an example of processing related to operation restriction in the information processing terminal 20. In the flowchart of FIG. 6, the start of the process is exemplified when the information processing terminal 20 that cooperates with the in-vehicle device 10 with which the communication connection is established receives an on / off notification regarding the operation restriction. The information processing terminal 20 receives the on notification or the off notification regarding the operation restriction notified from the in-vehicle device 10 connected via the communication module 111 (S31).

  The information processing terminal 20 determines whether or not the received operation restriction notification is an OFF notification (S32). If the operation restriction notification is an off notification (S32, “Yes”), the information processing terminal 20 proceeds to the process of S33. On the other hand, if the operation restriction notification is not an off notification (S32, “No”), the information processing terminal 20 proceeds to the process of S34.

  In the process of S33, the information processing terminal 20 cancels the display state of the screen whose operation is restricted. In the information processing terminal 20 for which the operation restriction has been released, various types of information related to an operation for using a predetermined function provided from the in-vehicle device 10 connected via the communication module 111 is displayed. The authenticated operator of the information processing terminal 20 performs an operation input for using a desired function based on various information displayed on the display screen, for example. The in-vehicle device 10 receives an operation input from the information processing terminal 20 for which the operation restriction has been released, and provides a predetermined function corresponding to the operation input. For example, the in-vehicle device 10 receives an operation input to a navigation function such as a change of destination. The in-vehicle device 10 also provides video content such as broadcast video and playback video of the TV channel selected by the operator via the display unit 105 and the speaker 107. After the process of S33, the process of FIG. 6 ends.

  In the process of S <b> 34, the information processing terminal 20 performs operation restriction and display restriction on the own terminal that is in cooperation with the in-vehicle device 10. For example, the information processing terminal 20 restricts a cooperative operation (information input, a call operation such as an operation menu) for using a predetermined function provided by the in-vehicle device 10 to be prohibited. In addition, the information processing terminal 20 regulates display of various information related to operations for using a predetermined function provided by the in-vehicle device 10. On the display screen of the information processing terminal 20 on which display restriction is performed, a navigation screen or the like in which the transition operation is permitted is displayed. After the process of S34, the process of FIG. 6 ends.

  As described above, in the in-vehicle system 1 according to the present embodiment, the NFC module 114 whose communication range is limited to a predetermined distance is used to cooperate with the in-vehicle device 10 in the traveling vehicle other than the driver. The information processing terminal 20 under operation by the passenger can be identified. The in-vehicle device 10 can release the operation restriction and display restriction during traveling for the specified information processing terminal 20. Further, in the information processing terminal 20, the operation restriction and the display restriction on the in-vehicle device 10 to be linked can be canceled based on the operation restriction OFF notification notified from the in-vehicle device 10. According to the in-vehicle system 1 according to the present embodiment, it is possible to operate the in-vehicle device 10 by a passenger other than the driver even during traveling.

  In the in-vehicle system 1 according to the present embodiment, for example, the in-vehicle device 10 can accept an operation input via the information processing terminal 20 for which the operation restriction has been released. Operation becomes possible. For example, when moving to a place where there is no land intuition, the destination can be set one after another while moving, so that the travel time can be shortened. Furthermore, since the user can freely select video content and the like, comfort during running is improved.

  In the in-vehicle system 1 according to the present embodiment, the NFC module 114 is provided for each seat on which a passenger of the vehicle is seated. Therefore, based on the device information acquired from the information processing terminal 20 via the NFC module 114 and the device information acquired from the information processing terminal 20 via the communication module 111 at the time of cooperation, the information processing terminal related to the operation By performing the authentication of 20, whether the actor who performed the authentication act to the NFC module 114 is a driver seated in the driver seat or a passenger other than the driver seated in the passenger seat or the rear seat Can be identified. According to the in-vehicle system 1 according to the present embodiment, the operator of the information processing terminal 20 that cooperates with the in-vehicle device 10 can be identified based on authentication during traveling to the information processing terminal 20 via the NFC module 114.

(Modification)
In the present embodiment, the in-vehicle device 10 has been described as acquiring device information of the adjacent information processing terminal 20 via the NFC module 114. The in-vehicle device 10 according to the modification may cause the information processing terminal 20 to read the identification number assigned to the NFC module via the NFC module 114 provided for each seat. The identification number assigned to the NFC module 114 is different for each seat. The information processing terminal 20 that executes the application notifies the in-vehicle device 10 of the identification number read via the NFC module 114 through the communication path related to the cooperation process. The in-vehicle device 10 authenticates the information processing terminal based on a match between the identification number of the NFC module 114 notified from the information processing terminal 20 and the identification number assigned to the NFC module 114. Also good. Also in the modified example, the operator of the information processing terminal 20 that cooperates with the in-vehicle device 10 can be identified based on the authentication during traveling to the information processing terminal 20 via the NFC module 114.

Further, in the authentication of the information processing terminal 20 that cooperates, a two-dimensional code or bar code that can be read only by the information processing terminal 20 that is brought close to the information processing terminal 20 may be used. The in-vehicle system 1 of the modified example arranges a two-dimensional code and a barcode that can be read only for the information processing terminal 20 that is brought close to each seat, and causes the information processing terminal 20 that is linked to read the code. Then, the information processing terminal 20 that executes the application may associate the read code information with the time information and notify the in-vehicle device 10 through the communication path related to the cooperation process. The in-vehicle device 10 can authenticate the information processing terminal based on the code information and time information notified from the information processing terminal 20. For example, the in-vehicle device 10 may be configured such that the notified code information matches a content indicated by a two-dimensional code or bar code provided in a seat other than the driver's seat, and the difference between the current time information and the notified time information. Can be used as an authentication condition. According to such a form, the vehicle-mounted system 1 of a modification can authenticate the information processing terminal 20 that does not have an NFC function.

<Second Embodiment>
[4. System configuration〕
FIG. 7 shows an example of the system configuration of the in-vehicle system 1 according to the second embodiment (hereinafter also referred to as this embodiment). The vehicle-mounted system 1 illustrated in FIG. 7 is an example of a form including a handle sensor 116 that detects a pressure held by a driver on a steering wheel 2d that is a steering component that steers the vehicle 2 that is running. The handle sensor 116 is an example of “detecting means”. Note that the in-vehicle system 1 illustrated in FIG. 7 is different from the in-vehicle system 1 illustrated in FIG. 1 by including a handle sensor 116. In the following, differences from FIG. 1 will be mainly described.

  In the in-vehicle system 1 illustrated in FIG. 7, the handle holding state of the driver who steers the traveling vehicle 2 is detected by providing the handle sensor 116. The handle sensor 116 is composed of, for example, a plurality of pressure sensors arranged at regular intervals in the circumferential direction of the steering wheel 2d. The detection signal of each pressure sensor is connected to the ECU via the in-vehicle network. In the ECU, for example, based on the detection signal of each pressure sensor, the grip position and location of the driver's steering hand gripping the steering wheel 2d are detected. The in-vehicle device 10 acquires, for example, a grip location detected by the ECU, and specifies the handle holding state of the driver's steering hand that steers the steering wheel 2d detected by the handle sensor 116. For example, when the vehicle-mounted device 10 has two gripping positions with respect to the steering wheel 2d detected by the handle sensor 116, the handle holding state is specified as a two-hand operation. Similarly, when the gripping position on the steering wheel 2d is one, the handle holding state is specified as a one-hand operation. In addition, when the grip location on the steering wheel 2d is not detected, it is specified as a state that does not correspond to either the two-handed operation or the one-handed operation (for example, not detected).

  The in-vehicle system 1 of the present embodiment activates a re-authentication timer to the information processing terminal 20 that is being authenticated via the NFC module 114 when the driver who steers the steering wheel 2d performs a driving operation using both hands. Stop. In the state where the activation of the re-authentication timer is stopped, the re-authentication restriction for the authenticated information processing terminal 20 is once released. For this reason, the passenger who operates the information processing terminal 20 can continue the cooperative operation to the in-vehicle device 10 via the information processing terminal. According to the in-vehicle system 1 according to the present embodiment, further improvement in convenience can be expected.

[5. Process flow
Hereinafter, with reference to FIGS. 8 and 9, processing related to operation restriction using the handle holding state of the in-vehicle system 1 according to the present embodiment will be described. In the second embodiment, the processing according to the first embodiment described with reference to FIGS. 3 to 6 is executed in the same manner.

  FIG. 8 is a flowchart illustrating an example of the update process of the handle holding state of the in-vehicle device 10. The process of FIG. 8 is periodically executed at regular intervals during the cooperation process. In the flowchart of FIG. 8, the in-vehicle device 10 acquires the gripping state of the steering wheel 2d by the driver's steering hand based on the detection signal detected by the handle sensor 116 (S41). In the in-vehicle device 10, the grip location on the steering wheel 2 d detected by the handle sensor 116 is acquired.

The in-vehicle device 10 specifies the handle holding state for the steering wheel 2d based on the acquired gripping state (S42). For example, the in-vehicle device 10 specifies that the handle holding state is due to a two-hand operation when there are two grip points on the steering wheel 2d. Similarly, based on the grip location on the steering wheel 2d, the handle holding state is identified as undetected that does not correspond to any one-hand operation, two-hand operation, or one-hand operation.

  The in-vehicle device 10 temporarily stores the specified handle holding state in association with time information in a predetermined area of the main storage unit 102. The handle holding information stored in the main storage unit 102 is periodically updated at periodic intervals at which the process of FIG. 8 is executed (S43). After the process of S43, the process of FIG.

  Next, FIG. 9 will be described. FIG. 9 is a flowchart illustrating an example of the re-authentication timer control process based on the handle holding information. The process in FIG. 9 is periodically executed at regular intervals during the cooperation process. In the flowchart of FIG. 9, the in-vehicle device 10 acquires handle holding information (S51). The in-vehicle device 10 acquires the latest handle holding information stored in a predetermined area of the main storage unit 102.

  The in-vehicle device 10 determines whether the steering wheel holding state of the driver's steering wheel 2d is a two-hand operation (S52). If the steering wheel holding state on the steering wheel 2d is not a two-hand operation (S52, “No”), the in-vehicle device 10 proceeds to the process of S54. On the other hand, when the steering wheel holding state on the steering wheel 2d is a two-hand operation (S52, “Yes”), the in-vehicle device 10 proceeds to the process of S53.

  In the process of S53, the in-vehicle device 10 stops activation of the re-authentication timer. For example, the in-vehicle device 10 invalidates the processing described with reference to FIG. As a result, in the in-vehicle device 10, the authentication flag state for the information processing terminal 20 authenticated via the NFC module 114 provided for each seat is maintained in the active state. Therefore, in the process of FIG. 3, the operation restriction OFF notification notified to the information processing terminal 20 is continued. The information processing terminal 20 can continue the cooperative operation to the in-vehicle device 10 via the information processing terminal. After the process of S53, the process of FIG. 9 is terminated.

  In the process of S54, the in-vehicle device 10 determines whether or not the re-authentication timer is in a stopped state. When the state of the re-authentication timer at the time of processing is in a stopped state (S54, “Yes”), the in-vehicle device 10 proceeds to the processing of S55. On the other hand, when the state of the re-authentication timer at the time of processing is not stopped (S54, “No”), the in-vehicle device 10 ends the processing of FIG.

  In the process of S55, the in-vehicle device 10 starts a re-authentication timer. By the process of S55, the in-vehicle device 10 can cancel the stop state of the re-authentication timer that has been stopped in the most recent re-authentication timer control process and make it function again. In the in-vehicle device 10 whose re-authentication timer is activated again, the information processing terminal 20 is re-authenticated via the NFC module 114 based on the set timer value. Since the stop state of the re-authentication timer can be canceled when the state of the driver's steering wheel gripping the steering wheel 2d is not a two-hand operation, for example, the lending of the information processing terminal 20 to a driver who operates with one hand is suppressed. it can. After the process of S55, the process of FIG. 9 is terminated.

As described above, in the in-vehicle system 1 according to the present embodiment, the handle holding state of the driver who operates the steering wheel 2d can be specified using the handle sensor 116. The in-vehicle system 1 can stop the activation of the re-authentication timer for the information processing terminal 20 being authenticated via the NFC module 114 when the steering wheel holding state during traveling is a two-hand operation. As a result, the information processing terminal 20 that cooperates with the in-vehicle device 10 maintains the state in which the restriction at the time of authentication is released, so that the passenger can continuously perform the cooperation operation via the information processing terminal. The in-vehicle system 1 can restart the stopped re-authentication timer when the steering wheel holding state during traveling is other than a two-hand operation. As a result, lending of the information processing terminal 20 operated by the passenger to the driver can be suppressed. According to the in-vehicle system 1 according to the present embodiment, further improvement in convenience can be expected.

(Modification)
In the second embodiment, the in-vehicle system 1 can specify that the steering wheel holding state of the driver who steers the traveling vehicle is a two-hand operation. In the in-vehicle system 1 of the modified example, when it is specified that the handle holding state is a two-hand operation, the operation restriction and display restriction for the in-vehicle device 10 may be released. This is because when the handle holding state is a two-handed operation, a passenger who can input an operation to the in-vehicle device 10 can be regarded as a passenger sitting in a passenger seat other than the driver. Therefore, in the in-vehicle system 1 of the modified example, the operation input of the passenger via the operation unit 104 is permitted by specifying that the handle holding state is a two-hand operation and canceling the travel restriction on the in-vehicle device 10. The In addition, in the in-vehicle device 10 whose travel restriction is released, it is possible to accept an operation input from the information processing terminal 20 connected to the communication module 111 without performing an authentication act via the NFC module 114.
