Description

The present invention relates to a communication control system and a communication control program.

Conventionally, it is known that a mobile terminal such as a smartphone and an in-vehicle system are connected by Bluetooth (registered trademark, hereinafter referred to as BT), and hands-free calling or the like is performed using a speaker, a microphone, or the like of the in-vehicle system. Once the mobile terminal and the in-vehicle system are registered for pairing, a hands-free connection will be automatically established from the next time onward if they are within the range of mutual wireless communication. Patent Document 1 describes that a connection between a hands-free device and a mobile phone is automatically established when a user is seated in the driver's seat of a vehicle. Further, Patent Document 2 describes that a hands-free connection between the navigation device and the mobile phone is automatically established when there is a mobile phone in the vicinity of the driver's seat.

Japanese Unexamined Patent Publication No. 2002-12091 Japanese Patent No. 46826287

The configuration that automatically establishes a connection when the paired registered in-vehicle system and the mobile terminal are within the range where wireless communication is possible is highly convenient, but it is said that it will be automatically connected even under unintended circumstances. There was a problem. For example, a couple shares one vehicle, the husband's mobile terminal has been registered for pairing with the vehicle's in-vehicle system for hands-free calling of BT, and the wife's mobile terminal has been registered for pairing with the in-vehicle system. Think about the case when you haven't done so. In this case, if the BT function of the husband's mobile terminal is ON, the BT function of the in-vehicle system is also ON, and both are within the range of mutual wireless communication, a hands-free connection is automatically established. NS. For example, while the husband is talking at home using the telephone function of the mobile terminal with the BT function ON, the wife is in a vehicle with the BT function of the in-vehicle system still ON (for example, the radio sound is output from the speaker). When you drive home, the mobile terminal and the in-vehicle system will be within the communicable range, and the in-vehicle system will establish a hands-free connection with the husband's mobile terminal that has been registered for pairing. As a result, the in-vehicle system functions as a hands-free unit of the husband's mobile terminal. Therefore, the husband at home cannot continue the call on his mobile terminal. Also, in the vehicle, the voice of the radio suddenly switches to the voice of the other party of the husband's call. Further, on the other party side, the conversation with the husband is suddenly interrupted, and the sound collected by the microphone in the vehicle begins to be heard. Such an inconvenience could occur due to the automatic connection function.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique for reducing the possibility that an in-vehicle system and a mobile terminal are unintentionally connected.

In order to achieve the above objectives, the communication control system includes a vehicle movement history acquisition unit that acquires the movement history of the vehicle, a mobile terminal movement history acquisition unit that acquires the movement history of the mobile terminal, and an in-vehicle system mounted on the vehicle. And the mobile terminal are within the range where short-range wireless communication is possible, and when the movement history of the vehicle and the movement history of the mobile terminal match, a connection for short-range wireless communication of a specific function is established. If the movement history of the vehicle and the movement history of the mobile terminal do not match, a connection control unit that does not establish a connection for short-range wireless communication of a specific function is provided.

Further, in order to achieve the above object, the communication control program is mounted on the vehicle movement history acquisition unit for acquiring the movement history of the vehicle, the mobile terminal movement history acquisition unit for acquiring the movement history of the mobile terminal, and the vehicle. For short-range wireless communication of a specific function when the in-vehicle system and the mobile terminal are within the range where short-range wireless communication is possible and the movement history of the vehicle and the movement history of the mobile terminal match. When the connection is established and the movement history of the vehicle and the movement history of the mobile terminal do not match, it functions as a connection control unit that does not establish a connection for short-range wireless communication of a specific function.

In this communication control system and communication control program, the movement history of the vehicle and the movement history of the mobile terminal are compared, and it is determined whether or not both movement histories match, that is, whether or not the mobile terminal has moved with the vehicle. Then, if both movement histories match, a connection for communication of a specific function is established, but if they do not match, the connection is not established. That is, a connection for communication of a specific function is established with the mobile terminal determined to have moved with the vehicle, but the connection is not established with the mobile terminal determined not to move with the vehicle. Therefore, according to the communication control system and the communication control program, the possibility that the in-vehicle system and the mobile terminal are unintentionally connected can be reduced.

The communication unit 45 includes a circuit for communicating with another device according to various communication standards. In the present embodiment, the control unit 20 can perform short-range wireless communication with the smartphone 50 in accordance with the BT standard via the communication unit 45.

The smartphone 50, which has been registered for pairing with the in-vehicle system 10, is generally automatically connected to the in-vehicle system 10 if it is within the communicable range according to the BT standard. Therefore, the user U _A can utilize readily hands-free communication function. However, in the case where the user U _A which carries a smartphone 50 and the vehicle-mounted system 10 even if it is in a communicable range by BT standards each other, the user U _A is not the case you are in the vehicle C There can be.

Figure 2A is a smart phone 50 and the user U _A smartphone 50 and the vehicle-mounted system 10 is in the communication range shows an example outside of the vehicle C. If, when paired registered both devices is configured to establish a connection for the handsfree call unconditionally if within the communicable range, at an unintended timing user U _A, the vehicle system 10 handsfree It is possible to switch to a call. For example, since the home user U _A is the user U _B is returning home by driving the vehicle C in-vehicle system 10 and the smart phone 50 during a call on your phone 50 becomes available for communication by BT, call is switched to handsfree You can assume that.

The communication control program 21 has a vehicle movement history acquisition unit 21a and a mobile terminal in order to realize a function of determining whether or not an automatic connection can be established for a hands-free call between the in-vehicle system 10 and the smartphone 50 that has been registered for pairing. It includes a movement history acquisition unit 21b and a connection control unit 21c. The vehicle movement history acquisition unit 21a is a program module that allows the control unit 20 to realize a function of acquiring a vehicle movement history. In the present embodiment, the movement history of the vehicle is the history of the position of the vehicle. When the ACC of the vehicle is ON, the control unit 20 acquires the current position every X seconds (X is, for example, 1) and records it on the recording medium 30 in association with the current time (vehicle movement history information 30b). .. The control unit 20 acquires the current position of the vehicle based on the outputs of the GNSS receiving unit 41, the vehicle speed sensor 42, and the gyro sensor 43. Further, the control unit 20 executes a known map matching process using the map information 30a to correct the current position of the vehicle. When ACC is OFF, the current position is not acquired and the vehicle movement history information 30b is not updated.

When the control unit 20 detects that there is a paired registered BT terminal in the communicable range of the BT by the function of the vehicle movement history acquisition unit 21a, the control unit 20 refers to the vehicle movement history information 30b and reaches the current time. Get the movement history of the default period of.

The mobile terminal movement history acquisition unit 21b is a program module that allows the control unit 20 to realize a function of acquiring the movement history of the mobile terminal. In the present embodiment, the movement history of the mobile terminal is the history of the position of the mobile terminal. As described above, in the smartphone 50, the history of the current position every X seconds is accumulated as the mobile terminal movement history information 70a. When it is detected that there is a paired registered BT terminal in the communication range of the BT, the control unit 20 transmits the movement history for a predetermined period up to the current time by the function of the mobile terminal movement history acquisition unit 21b. To request. Then, the control unit 20 acquires the mobile terminal movement history information 70a transmitted from the smartphone 50 in response to the request.

The connection control unit 21c has a specific function when the in-vehicle system mounted on the vehicle and the mobile terminal exist in a range where short-range wireless communication is possible and the movement history of the vehicle and the movement history of the mobile terminal match. This is a program module that enables the control unit 20 to realize a function of establishing a connection for short-range wireless communication and not establishing the connection if they do not match. In this embodiment, the specific function is a hands-free call function. When the control unit 20 detects the mobile terminal registered for pairing by the BT by the function of the connection control unit 21c, the control unit 20 compares the movement history of the vehicle for a predetermined period with the movement history of the smartphone 50.

In the present embodiment, the movement history is the history of the current position every X seconds. FIG. 3A shows an example of the time when the position is recorded as the movement history in the predetermined period up to the current time. For example, the time indicated by the white circle is the time when the position of the vehicle is recorded, and the black circle is the time when the position of the smartphone 50 is recorded. The distance between the white circles and the distance between the black circles is X seconds. The control unit 20 calculates the distance between the white circle and the black circle, which have the smallest time difference, from the position of the vehicle at the time indicated by the white circle and the position of the smartphone 50 at the time indicated by the black circle. The control unit 20 calculates the distance for all the sets included in the predetermined period. In the present embodiment, the control unit 20 determines that the movement history of the vehicle and the movement history of the smartphone 50 match when the distance between the two is greater than the reference% of the total number of groups, and when the distance between the two is less than the default value, the movement history of the smartphone 50 matches. Determines that the movement history does not match.

The position of the vehicle is acquired by adopting autonomous navigation, map matching, and the like. On the other hand, it is known that the position of the smartphone 50 may change as if it were moving even if the smartphone 50 is stopped, and an error may be temporarily included. Therefore, in general, the position of the vehicle has less error and higher accuracy than the position of the smartphone 50. As the default value, the distance (for example, about 2 m) when the smartphone 50 is in the vehicle interior of the vehicle C may be assumed. In the case of the present embodiment, it is determined that the movement histories match when the number of pairs whose distance is less than the default value is greater than the reference% of the total number of pairs. Due to a temporary positioning error of the smartphone 50, even if the smartphone 50 is in the vehicle, the distance between the two may be larger than the default value. Compared with the configuration in which it is determined whether or not the smartphone 50 is in the vehicle based on a set of distances, in the case of the present embodiment, it is possible to reduce the influence of the positioning error of the smartphone 50 in the determination of the match / mismatch of the movement history. can.

When it is determined that the movement histories match, the control unit 20 establishes a connection for a hands-free call by the function of the connection control unit 21c. That is, the control unit 20 establishes a BT connection according to the hands-free profile, and makes it possible to make a call, transfer a call voice, and the like.

For example in FIG. 2A, the time when the user U _B comes home driving a vehicle C, and when the smartphone 50 and the in-vehicle system 10 of the indoor becomes within communication range (Example 1), becomes available for communication The movement history of both of them in the default period up to is not the same. Therefore, according to the present embodiment, the BT connection for hands-free calling is not established. As a result, it is possible to prevent that the user U _A is switched at an undesired timing, the call during a call for instance at home switch to hands-free vehicle system 10.

Incidentally, if the user U _A is turned ON BT function of the smartphone 50 brought in the vehicle system 10 and the car while driving the vehicle C (Example 2), for a defined interval up to the time when they became communicable There is a high possibility that the movement histories of both will match. If they match, the control unit 20 establishes a BT connection for a hands-free call, and makes it possible to make a call, transfer a call voice, and the like.

As described above, in the case of the present embodiment, the movement history of the vehicle and the movement history of the mobile terminal are compared, and it is determined whether or not both movement histories match, that is, whether or not the mobile terminal has moved with the vehicle. .. Then, if both movement histories match, a connection for the hands-free call function is established, but if they do not match, the connection is not established. That is, the connection is established with the mobile terminal determined to have moved with the vehicle, but the connection is not established with the mobile terminal determined not to move with the vehicle. Therefore, according to the present embodiment, it is possible to reduce the possibility that the in-vehicle system and the mobile terminal are unintentionally connected hands-free. Further, in this embodiment, since the user U _A is no need for other sensors (e.g., occupancy sensor, etc.) for detecting whether there in the passenger compartment of the vehicle C, possible to suppress the increase of the cost.

Next, consider Example 3 and Example 4 in which there is no movement history to be compared. Example 3 is a case where the user _{U A} starts operating boarded with smartphone 50 of BT function ON in the vehicle C (ON the ACC) (see Figure 2B). Example 4 is a case where the user _{U A} is cage to the outside of the vehicle of the vehicle C near with smartphone 50 of BT function ON, and start operation boarded the vehicle C user _{U B} (ON the ACC) (see Figure 2A ).

In both the case of Example 3 and the case of Example 4, when the ACT function of the smartphone 50 is ON and the ACC of the vehicle C is ON (as a result, the BT function of the in-vehicle system 10 is also ON), both can communicate with each other. However, there is no movement history of the vehicle C in the predetermined period until the time when communication becomes possible (for example, the white circle shown in FIG. 3A does not exist). In this case, in the present embodiment, whether or not the distance between the smartphone 50 and the in-vehicle system 10 is similar to the distance between the smartphone 50 and the in-vehicle system 10 when both are BT-connected for hands-free calling in the past. It is configured to make a BT connection for a hands-free call if it is similar.

Therefore, in the present embodiment, the control unit 20, the possible communication in a case where the smartphone 50 of the user U _A and the in-vehicle system 10 detects that it is now the state was not able to communicate with a communicable state The distance between the two when the movement history of the predetermined period up to the detected time exists in both is acquired, and is stored in the recording medium 30 together with the match / mismatch information of the movement history. It should be noted that, in the case where the smartphone 50 and the in-vehicle system 10 are in a state where communication is possible from a state in which communication is not possible, there is a movement history of a predetermined period up to the time when communication is possible in both cases. For example, the above-mentioned Examples 1 and 2 may be assumed.

In the case of Example 1, as shown in FIG. 2A, the smartphone 50 is outside the vehicle C. The distance acquired in this case is D2. In the case of Example 2, as shown in FIG. 2B, the smartphone 50 is in the passenger compartment of the vehicle C. The distance acquired in this case is D1. In the case of Example 2, since the movement histories of both parties in the predetermined period up to the time when communication becomes possible match, the information indicating that the movement histories match is accumulated together with D1. In the case of Example 1, since the movement histories of the two do not match in the predetermined period until the time when communication becomes possible, the information to the effect of the inconsistency is accumulated together with D2.

FIG. 3B shows an example of a histogram of the distance D1 in Example 2 and the distance D2 in Example 1. As shown in FIG. 3B, the distance corresponding to the peak value of the frequency distribution of both distances when the movement histories match and the distance corresponding to the peak value of the frequency distribution of both distances when the movement histories do not match are It's different. Further, the distance corresponding to the former peak is smaller than the distance corresponding to the latter peak. The control unit 20 calculates the distance corresponding to the valley between the two peak values as a threshold value based on hiss and grams.

In the case of Example 3 and Example 4 (when there is no movement history for the predetermined period of vehicle C because it is immediately after ACC ON), the control unit 20 calculates the distance between the two based on the current positions (latest positions) of the two. .. Then, the control unit 20 establishes a connection for a hands-free call when the calculated distance is equal to or less than the threshold value. Therefore, for example, even if the distance calculated in the case of Example 3 is larger than the default value due to the temporary positioning error of the smartphone 50, if it is smaller than the threshold value, automatic connection is possible. Therefore the user U _A can increase the possibility of enjoying the convenience of automatic connection. Further, when the calculated distance is larger than the threshold value, the control unit 20 does not establish a connection for a hands-free call. Therefore, for example, in the case of Example 4, it is possible to reduce the possibility of being automatically despite the user U _A is not intended connection.

(2) Automatic connection control processing:
Next, the automatic connection control process executed by the control unit 20 will be described with reference to FIG. In the automatic connection control process, the in-vehicle system 10 detects that the BT terminal exists in the BT communication range from the state in which the in-vehicle system 10 does not detect the existence of the BT terminal in the BT communication range. This is a process executed when the state changes (for example, Examples 1 to 4).

When the automatic connection control process is started, the control unit 20 acquires the identification information of the smartphone 50 by the function of the connection control unit 21c (step S100). That is, the control unit 20 requests the smartphone 50 that has detected the existence to transmit the identification information via the communication unit 45, and receives the identification information transmitted from the smartphone 50 in response to the request.

Subsequently, the control unit 20 determines whether or not pairing has been registered by the function of the connection control unit 21c (step S105). That is, the control unit 20 determines whether or not the smartphone 50 is a terminal that has been registered for pairing with the in-vehicle system 10 based on the identification information acquired in step S100.

If it is not determined in step S105 that the pairing has been registered, the control unit 20 ends the automatic connection control process. Therefore, the connection between the in-vehicle system 10 and the smartphone 50 for hands-free calling is not automatically established. In this case, it is possible to return to the state of waiting for the detection of the BT terminal again.

When it is determined in step S105 that the pairing has been registered, the control unit 20 acquires the movement history of the smartphone 50 by the function of the mobile terminal movement history acquisition unit 21b (step S110). That is, the control unit 20 requests the smartphone 50 to transmit the mobile terminal movement history information 70a for a predetermined period up to the present via the communication unit 45, and the smartphone 50 transmits the mobile terminal movement history information 70a in response to the request. Receives mobile terminal movement history information 70a.

Subsequently, the control unit 20 determines whether or not there is a movement history of the vehicle-mounted system 10 by the function of the vehicle movement history acquisition unit 21a (step S115). That is, the control unit 20 refers to the vehicle movement history information 30b recorded on the recording medium 30 and determines whether or not there is a movement history for a predetermined period up to the present.

When it is determined in step S115 that there is a movement history, the control unit 20 determines whether or not the movement histories of the two match or not by the function of the connection control unit 21c (step S120). For example, in the present embodiment, as shown in FIG. 3A, the control unit 20 calculates the distance between the two sets in the predetermined period. When the distance between the two is greater than the reference% of the total number of pairs, the control unit 20 determines that the movement histories of the two are the same.

If it is not determined in step S120 that the movement histories match, the control unit 20 ends the automatic connection control process. Therefore, the connection between the in-vehicle system 10 and the smartphone 50 for hands-free calling is not established. In this case, the touch panel display of the user I / F unit 44 indicates that the smartphone 50 that has been registered for pairing exists in the communicable range but does not automatically make a connection for hands-free calling, and the vehicle. The connection for hands-free calling may be established if the occupant of C chooses to connect, and may not be established if not selected.

When it is determined in step S120 that the movement histories match, the control unit 20 establishes a connection with the smartphone 50 for a hands-free call by the function of the connection control unit 21c (step S125), and automatically connects control processing. To finish. That is, the control unit 20 establishes a connection for a hands-free call with the smartphone 50 according to the hands-free profile.

If it is not determined in step S115 that there is a movement history, the control unit 20 determines whether or not the distance between the in-vehicle system 10 and the smartphone 50 is equal to or less than the threshold value by the function of the connection control unit 21c (step). S130). That is, the control unit 20 requests the smartphone 50 to transmit the current position via the communication unit 45, and receives the current position transmitted from the smartphone 50 in response to the request. Further, the control unit 20 acquires the current position of the in-vehicle system 10 by positioning using the output of the GNSS receiving unit 41 or the like. Then, the control unit 20 calculates the distance between the current position of the in-vehicle system 10 and the current position of the smartphone 50, and determines whether or not the calculated distance is equal to or less than the threshold value.

When it is determined in step S130 that the distance between the two is equal to or less than the threshold value, the control unit 20 executes step S125. That is, a connection for hands-free calling is established. If it is not determined in step S130 that the distance between the two is equal to or less than the threshold value, the control unit 20 ends the automatic connection control process. Therefore, the connection between the in-vehicle system 10 and the smartphone 50 for hands-free calling is not established. In this case, the touch panel display of the user I / F unit 44 indicates that the smartphone 50 that has been registered for pairing exists in the communicable range but does not automatically make a connection for hands-free calling, and the vehicle. The connection for hands-free calling may be established if the occupant of C chooses to connect, and may not be established if not selected.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention, and various other embodiments can be adopted. For example, the mobile terminal side may acquire the movement history of the in-vehicle system, and the mobile terminal may determine the match / mismatch of the movement histories of the two. Further, for example, the communication control system may be realized by a server, a mobile terminal, and an in-vehicle system. When the communication control system is realized by the server, the mobile terminal, and the in-vehicle system, the movement history of the vehicle and the movement history of the mobile terminal are periodically uploaded and accumulated in the server with the same user ID, and the movement history matches. / Mismatch may adopt the configuration determined by the server.

In addition, a part of the configurations of the above-described embodiment may be omitted, and the order of processing may be changed or omitted. Further, the in-vehicle system and the mobile terminal need only be able to communicate according to a wireless communication standard capable of short-range wireless communication when both are within the communicable range, and even if communication is performed according to a standard other than the BT standard. good.

The mobile terminal may be a device capable of performing short-range wireless communication in accordance with the BT standard, and for example, a smartphone, a tablet, a smart speaker, a music playback terminal, or the like may be assumed.

The connection control unit may have a configuration in which a connection for short-range wireless communication of a specific function is established when the movement histories of the mobile terminal and the vehicle match, and the connection is not established when the movement histories do not match. Various configurations can be adopted. For example, the movement history of the vehicle may be the history of the movement speed of the vehicle, and the movement history of the mobile terminal may be the history of the movement speed of the mobile terminal. That is, if the mobile terminal is moving together with the vehicle, it can be considered that the history of the moving speeds of both are the same except for some errors. Therefore, if the movement speed history does not match, it can be considered that the mobile terminal is not moving with the vehicle. In this case, the mobile terminal is used by not establishing a connection for short-range wireless communication of a specific function. It is possible to reduce the possibility that the in-vehicle system is connected to a specific function at an unintended timing. In the mobile terminal and the in-vehicle system, the moving speed may be the ground speed calculated by utilizing the Doppler effect between the GNSS receiving unit and the satellite. The movement speed is recorded as a movement history in association with the calculated time. Of course, in the case of a vehicle, the moving speed acquired based on the output signal of the vehicle speed sensor and the time may be recorded in association with each other. The movement history of the vehicle and the movement history of the mobile terminal may be the history of the movement direction (for example, the angle with respect to true north). The moving direction can be acquired based on, for example, a signal received by the GNSS receiving unit.

The short-range wireless communication of the specific function may be a communication for inputting / outputting the sound or video of the mobile terminal to the user I / F unit of the in-vehicle system. For example, it may be communication for hands-free calling. Further, for example, the communication may be for transmitting audio data reproduced by the codec unit 84. Even if the movement histories do not match, a short-range wireless communication connection other than the specific function may be established.

Further, the connection control unit does not have at least one of the movement history of the vehicle in the default period up to the current time and the movement history of the mobile terminal in the default period up to the current time. If the distance between the current position of the vehicle and the current position of the mobile terminal is less than or equal to the threshold, a connection for short-range wireless communication of a specific function is established, and if the distance is larger than the threshold, for short-range wireless communication of a specific function. A configuration may be adopted in which the connection is not established. In the above embodiment, as shown in Examples 3 and 4, it is assumed that there is no vehicle movement history in (at least a part of) the default period, but the movement history of the mobile terminal in the default period is Even when it does not exist or when the movement history of both the mobile terminal and the vehicle in the predetermined period does not exist, it may be determined whether or not the connection is possible depending on whether or not the latest distance between the two is equal to or less than the threshold value. As an example in which the movement history of the mobile terminal does not exist, it may be assumed that the GNSS signal reception function is turned off, the power supply is turned off, and the like.

Further, as in the present invention, when the in-vehicle system and the mobile terminal exist in a range where short-range wireless communication is possible, and when the movement histories of the vehicle and the mobile terminal match, the short-range wireless communication of a specific function can be performed. The method of establishing a connection for the purpose and not establishing the connection if they do not match can also be applied as a program or a method. In addition, the above systems, programs, and methods may be realized as a single device or may be realized by using parts shared with each part provided in the vehicle, including various aspects. It is a program. In addition, some of them are software and some of them are hardware, which can be changed as appropriate. Further, the invention is also established as a recording medium for a program that controls a system. Of course, the recording medium of the program may be a magnetic recording medium or a semiconductor memory, and any recording medium to be developed in the future can be considered in exactly the same way.
