Description

Technical Field

[0001] The present disclosure relates to a wireless communication linkage control device. Background Art

[0002] Generally, an audio video navigation telematics (AVNT) system of a vehicle provides various conveniences to vehicle passengers by integrating various electronic devices such as an audio device, a video device, a navigation device, and a telematics device installed in the vehicle.

[0003] As such, the AVNT system has a plurality of electronic devices integrated therein, and includes various functions and menus.

[0004] The AVNT system wirelessly communicates with a mobile terminal such as a smartphone held by a passenger and provides convenience to the passengers of the vehicle.

[0005] When a mobile terminal held by a vehicle passenger is located in the vehicle, the AVNT system of the vehicle automatically and wirelessly communicates with the mobile terminal of the vehicle passenger through a wireless communication function such as Bluetooth.

[0006] However, when a vehicle passenger's mobile terminal wirelessly linked to the vehicle's AVNT system moves out of the vehicle from inside the vehicle, the problem is that the vehicle's AVNT system maintains the wireless communication linkage with the mobile terminal located outside the vehicle and does not release the wireless communication linkage, thereby causing inconvenience to the user.

[0007] In addition, when the driver's mobile terminal and the passenger's mobile terminal are each wirelessly linked to the AVNT system, and then the wireless communication linkage is released again inside the vehicle, if the driver's mobile terminal is removed from the vehicle, the driver's mobile terminal located outside the vehicle maintains the wireless communication linkage and does not release the wireless communication linkage with the AVNT system, but there is a problem, that is, the passenger's mobile terminal located inside the vehicle cannot be wirelessly linked to the AVNT system.

[0008] In this way, conventionally, there has been a problem in wireless communication linkage error, whereby the wireless communication linkage between a mobile terminal located outside the vehicle and the AVNT system of the vehicle is maintained rather than released.

[0009] Therefore, in the future, it is necessary to develop a wireless communication linkage control device for reliably controlling the maintenance or release of the wireless communication linkage with a mobile terminal according to the location of the mobile terminal. Summary of the invention

[0010] The present disclosure relates to a wireless communication linkage control device.

[0025] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. However, the present disclosure can be implemented in various ways and is not limited to the embodiments described herein. In the accompanying drawings, in order to clearly describe the present disclosure, parts that are not related to the description of the present disclosure will be omitted, and similar parts are represented by similar reference numerals throughout the specification.

[0026] Throughout the specification, when a part "includes" a component, it does not exclude other components, and other components may be further included unless otherwise specified. The terms "unit", "device / operator" and "module" described in the specification represent a unit for processing at least one function or operation, which can be implemented by hardware, software or a combination thereof.

[0027] Throughout the specification, when a part "includes" a component, it means not excluding other components, and other components may be further included unless otherwise stated. The same reference numerals will be used throughout the drawings to designate the same or similar parts.

[0028] In the following, reference will be made to Figures 1 to 5 An apparatus and method for controlling wireless communication linkage in a vehicle to which embodiments of the present disclosure are applicable are described in detail.

[0029] The wireless communication linkage control apparatus in a vehicle according to an embodiment of the present disclosure may be applied to an audio video navigation telematics (AVNT) system, but is not limited thereto.

[0030] Figure 1 1 is a diagram for explaining a vehicle provided with a wireless communication linkage control device according to an embodiment of the present disclosure. Figure 2 It is a diagram for explaining a position signal transmitter of a wireless communication linkage control device provided in a vehicle.

[0031] like Figure 1 As shown, the vehicle 10 may include a sensing device 300 for sensing state information of the vehicle 10 , and a wireless communication linkage control device 100 for releasing wireless communication linkage with the mobile terminal 200 when the current location of the mobile terminal 200 is outside the vehicle.

[0032] Here, when the mobile terminal 200 is in wireless communication linkage, the wireless communication linkage control device 100 can obtain the status information of the vehicle 10 from the sensing device 300, can determine the position determination method of the mobile terminal 200 based on the acquired vehicle status information, can use the determined position determination method to determine the current position of the mobile terminal 200, and when the current position of the mobile terminal 200 is outside the vehicle, the wireless communication linkage with the mobile terminal 200 can be released.

[0033] For example, the mobile terminal 200 may include a portable phone, a smart phone, a laptop computer, a digital broadcast terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation device, a tablet personal computer (PC), a tablet computer, an ultrabook, a wearable device (e.g., a smart watch, smart glasses, or a head-mounted display (HMD)), etc.

[0034] like Figure 2 As shown, the wireless communication linkage control device 100 may include a position signal transmitter 120 for sending a position signal to a mobile terminal.

[0035] Here, the location signal transmitter 120 may be a communication device for transmitting a location signal to the mobile terminal 200 in order to identify the location of the mobile terminal 200 , and may include a Bluetooth Low Energy (BLE) beacon, but the present disclosure is not limited thereto.

[0036] For example, the position signal transmitter 120 may be provided in each of the front door 30 , the rear door 40 , and the center fascia 20 of the vehicle 10 , but the present disclosure is not limited thereto.

[0037] The location signal transmitter 120 may be used when determining the current location of the mobile terminal 200 based on a location determination method using a high frequency sound technology, a location determination method using a trilateration technology, a location determination method using a fingerprint technology, etc. among the location determination methods of the mobile terminal 200.

[0038] When acquiring the state information of the vehicle 10 , the wireless communication linkage control device 100 may acquire information on the opening and closing of the windows of the vehicle and information on the current position of the vehicle.

[0039] This is because it is necessary to determine the optimum position determination method among the position determination methods of the mobile terminal 200 based on the information of the vehicle 10 .

[0040] Then, when determining the location determination method of the mobile terminal 200 , the wireless communication linkage control device 100 may apply a weight of the location determination method of the mobile terminal 200 based on the state information of the vehicle 10 , and may determine the location determination method of the mobile terminal 200 based on the applied weight.

[0041] Here, when the wireless communication linkage control apparatus 100 applies weights, a method of applying the weights of the location determination method of the mobile terminal 200 may be changed according to the state information of the vehicle 10 .

[0042] Then, when determining the location determination method of the mobile terminal 200, the wireless communication linkage control device 100 can check the weight of each location determination method applied to the mobile terminal 200, select the location determination method to which the highest weight is applied, and determine the selected location determination method as the location determination method of the mobile terminal.

[0043] For example, when the wireless communication linkage control device 100 determines the current position of the mobile terminal 200, if the determined position determination method is a position determination method using high-frequency sound technology, the wireless communication linkage control device 100 may determine whether the mobile terminal 200 recognizes the high-frequency sound of the signal received from the position signal transmitter 120 based on the signal information of the position signal transmitter 120 received from the mobile terminal 200, and in this regard, when it is determined that the mobile terminal 200 recognizes the high-frequency sound of the position signal transmitter 120, the wireless communication linkage control device 100 may determine that the current position of the mobile terminal 200 is inside the vehicle of the mobile terminal 200, and when it is determined that the mobile terminal 200 cannot recognize the high-frequency sound of the position signal transmitter 120, the wireless communication linkage control device 100 may determine that the current position of the mobile terminal 200 is outside the vehicle.

[0044] Here, the wireless communication linkage control device 100 may perform a position determination method using a high frequency sound technology using any one of the position signal transmitters 120 provided on each of the front door 30 , the rear door 40 , and the center fascia 20 of the vehicle 10 .

[0045] In another example, when the wireless communication linkage control device 100 determines the current position of the mobile terminal 200, if the determined position determination method is a position determination method using a trilateral measurement technique, the wireless communication linkage control device 100 may perform trilateral measurement based on signal information of the first, second and third position signal transmitters 120 received from the mobile terminal 200 to calculate the current position of the mobile terminal 200, and may determine whether the current position of the mobile terminal 200 is inside or outside the vehicle based on the calculated current position of the mobile terminal 200.

[0046] Here, the wireless communication linkage control device 100 can use a first position signal transmitter 120 set in the front door 30 of the vehicle 10, a second position signal transmitter 120 set in the rear door 40, and a third position signal transmitter 120 set in the center instrument panel 20 to perform a position determination method using a trilateral measurement technology.

[0047] In another example, when the wireless communication linkage control device 100 determines the current location of the mobile terminal 200, if the determined location determination method is a location determination method using fingerprint technology, the wireless communication linkage control device 100 can extract signal strength information from the signal information of the location signal transmitter 120 received from the mobile terminal 200, and can search for the current location of the mobile terminal 200 from a radio map including signal strength values ​​corresponding to vehicle interior space units based on the extracted signal strength, and can determine whether the current location of the mobile terminal 200 is inside or outside the vehicle based on the retrieved current location of the mobile terminal 200.

[0048] Here, the radio map including signal strength values ​​corresponding to the vehicle interior space units may be pre-stored in a vehicle memory or may be received from an external server.

[0049] In another example, when the wireless communication linkage control device 100 determines the current position of the mobile terminal 200, if the determined position determination method is a position determination method using the position information of the mobile terminal 200, the wireless communication linkage control device 100 can receive global positioning system (GPS) information including position information from the mobile terminal, and can calculate the distance or speed difference between the vehicle and the mobile terminal based on the GPS information of the mobile terminal and the GPS information as the vehicle position signal, and determine the current position of the mobile terminal based on the calculated distance or speed difference.

[0050] Figure 3Detailed description of the invention is a block diagram for explaining a wireless communication linkage control device in a vehicle according to an embodiment of the present disclosure.

[0051] like Figure 3 As shown, the wireless communication linkage control device 100 according to an embodiment of the present disclosure may include a communicator 110 wirelessly linked to a mobile terminal located inside a vehicle, a position signal transmitter 120 for transmitting a position signal to the mobile terminal, and a controller 130 for controlling the communicator 110.

[0052] Here, the communicator 110 may include a Bluetooth module, and may be wirelessly linked with the mobile terminal via Bluetooth, but the present disclosure is not limited thereto.

[0053] The location signal transmitter 120 may include a Bluetooth Low Energy (BLE) beacon, but the present disclosure is not limited thereto.

[0054] For example, the position signal transmitter 120 may be provided at each of a front door, a rear door, and a center fascia of the vehicle, but the present disclosure is not limited thereto.

[0055] Then, when the mobile terminal is in wireless communication linkage, the controller 130 can obtain the vehicle status information, determine the location determination method of the mobile terminal based on the acquired vehicle status information, determine the current location of the mobile terminal using the determined location determination method, and when the current location of the mobile terminal is outside the vehicle, the communicator 110 can be controlled to release the wireless communication linkage with the mobile terminal.

[0056] Here, when acquiring the state information of the vehicle, the controller 130 may acquire information about opening and closing of windows of the vehicle and information about the current position of the vehicle.

[0057] For example, the controller 130 may acquire information about opening and closing of a window from a window sensor, and may acquire information about a current position of the vehicle from a vehicle navigation device.

[0058] When determining the location determination method of the mobile terminal, the controller 130 may apply a weight of the location determination method of the mobile terminal based on the state information of the vehicle, and may determine the location determination method of the mobile terminal based on the applied weight.

[0059] For example, when applying weights, the controller 130 may apply weights of a first position determination method using high-frequency sound technology, a second position determination method using trilateration technology, a third position determination method using fingerprint technology, and a fourth position determination method using the location information of the mobile terminal among the position determination methods of the mobile terminal.

[0060] When the controller 130 applies the weight, the method of applying the weight of the location determination method of the mobile terminal may be changed according to the state information of the vehicle.

[0061] For example, when the controller 130 applies weights, if the controller 130 determines based on the vehicle's status information that the window is closed and the vehicle's current location is not an urban area, the controller 130 may apply the weight of the mobile terminal's location determination method to the first weight application method.

[0062] In another example, when controller 130 applies weights, if controller 130 determines based on the vehicle's status information that the window is closed and the vehicle's current location is an urban area, controller 130 may apply the weight of the mobile terminal's location determination method to the second weight application method.

[0063] In another example, when controller 130 applies weights, if controller 130 determines based on the vehicle's status information that the window is open and the vehicle's current location is not an urban area, controller 130 may apply the weight of the mobile terminal's location determination method to the third weight application method.

[0064] In another example, when controller 130 applies weights, if controller 130 determines based on the vehicle's status information that the window is open and the vehicle's current location is an urban area, controller 130 may apply the weight of the mobile terminal's location determination method to the fourth weight application method.

[0065] Here, when it is determined that the windows are closed according to the state information of the vehicle, the controller 130 may determine whether all the windows are closed.

[0066] When determining whether the windows are open based on the state information of the vehicle, the controller 130 may determine whether at least one window is open.

[0067] When the controller 130 applies weights, if the controller 130 determines based on the vehicle's status information that the windows are closed and the vehicle's current location is not in the urban area, the controller 130 may apply a first weight as the highest weight in the location determination method of the mobile terminal to the location determination method using the high-frequency sound technology, may apply a second weight lower than the first weight to the location determination method using the location information of the mobile terminal, and may apply a third weight lower than the second weight to the location determination method using the trilateral measurement technology and the location determination method using the fingerprint technology.

[0068] For example, the controller 130 may apply a weight of approximately 80% to a positioning method using high-frequency sound technology, may apply a weight of approximately 10% to a positioning method using location information of a mobile terminal, and may apply a weight of approximately 5% to each of a positioning method using trilateration technology and a positioning method using fingerprint technology.

[0069] In another case, when the controller 130 applies weights, if the controller 130 determines based on the status information of the vehicle that the windows are closed and the current location of the vehicle is in the urban area, the controller 130 may apply the first weight as the highest weight in the location determination method of the mobile terminal to the location determination method using the high-frequency sound technology, may apply a second weight lower than the first weight to the location determination method using the fingerprint technology, and may apply a third weight lower than the second weight to the location determination method using the trilateral measurement technology and the location determination method using the location information of the mobile terminal.

[0070] For example, the controller 130 may apply a weight of approximately 80% to a positioning method using high-frequency sound technology, may apply a weight of approximately 10% to a positioning method using fingerprint technology, and may apply a weight of approximately 5% to each of a positioning method using trilateration technology and a positioning method using location information of a mobile terminal.

[0071] In another case, when the controller 130 applies weights, if the controller 130 determines based on the status information of the vehicle that the windows are closed and the current location of the vehicle is not in the urban area, the controller 130 may apply the same weight to the location determination method using high-frequency sound technology, the location determination method using the location information of the mobile terminal, the location determination method using trilateral measurement technology, and the location determination method using fingerprint technology in the location determination method of the mobile terminal.

[0072] For example, the controller 130 may apply a weight of approximately 25% to each of a location determination method using a high frequency sound technology, a location determination method using location information of a mobile terminal, a location determination method using a trilateration technology, and a location determination method using a fingerprint technology.

[0073] In another case, when the controller 130 applies weights, if the controller 130 determines based on the status information of the vehicle that the window is open and the current location of the vehicle is in the urban area, the controller 130 may apply a first weight as the highest weight to the location determination method using fingerprint technology in the location determination method of the mobile terminal, may apply a second weight lower than the first weight to each of the location determination method using high-frequency sound technology and the location determination method using trilateral measurement technology, and may apply a third weight lower than the second weight to the location determination method using the location information of the mobile terminal.

[0074] For example, the controller 130 may apply a weight of approximately 35% to a location determination method using fingerprint technology, may apply a weight of approximately 25% to each of a location determination method using high-frequency sound technology and a location determination method using trilateration technology, and may apply a weight of approximately 15% to a location determination method using location information of a mobile terminal.

[0075] Then, when determining the location determination method of the mobile terminal, the controller 130 may check the weight of each location determination method applied to the mobile terminal, may select the location determination method to which the highest weight is applied, and may determine the selected location determination method as the location determination method of the mobile terminal.

[0076] When the controller 130 determines the current position of the mobile terminal, if the determined position determination method is a position determination method using high-frequency sound technology, the controller 130 can determine whether the mobile terminal recognizes the high-frequency sound of the signal received from the position signal transmitter 120 based on the signal information of the position signal transmitter 120 received from the mobile terminal, and, when it is determined that the mobile terminal recognizes the high-frequency sound of the position signal transmitter 120, the controller 130 can determine that the current position of the mobile terminal is inside the vehicle.

[0077] Here, when the controller 130 determines whether the mobile terminal recognizes the high-frequency sound of the signal received from the position signal transmitter 120, if the controller 130 determines that the mobile terminal does not recognize the high-frequency sound of the position signal transmitter 120, the controller 130 may determine that the current position of the mobile terminal is outside the vehicle.

[0078] As needed, when the controller 130 determines the current position of the mobile terminal, if the determined position determination method is a position determination method using a trilateral measurement technique, the controller 130 may perform trilateral measurement based on signal information of the first, second and third position signal transmitters 120 received from the mobile terminal to calculate the current position of the mobile terminal, and may determine whether the current position of the mobile terminal is inside or outside the vehicle based on the calculated current position of the mobile terminal.

[0079] In another case, when the controller 130 determines the current location of the mobile terminal, if the determined location determination method is a location determination method using fingerprint technology, the controller 130 may extract signal strength from signal information of the location signal transmitter 120 received from the mobile terminal, may search for the current location of the mobile terminal from a radio map including signal strength values ​​corresponding to spatial units inside the vehicle based on the extracted signal strength, and may determine whether the current location of the mobile terminal is inside or outside the vehicle based on the retrieved current location of the mobile terminal.

[0080] In another case, when the controller 130 determines the current location of the mobile terminal, if the determined location determination method is a location determination method using the location information of the mobile terminal, the controller 130 may receive global positioning system (GPS) information including location information from the mobile terminal, may calculate the distance or speed difference between the vehicle and the mobile terminal based on the GPS information of the mobile terminal and the GPS information as the location signal of the vehicle, and may determine the current location of the mobile terminal based on the calculated distance or speed difference.

[0081] In this way, according to the implementation mode of the present disclosure, the location determination method of the mobile terminal can be determined based on the status information of the vehicle to determine the current location of the mobile terminal, so that the maintenance and release of the wireless communication linkage with the mobile terminal can be reliably and optimally controlled according to the location of the mobile terminal.

[0082] For example, when a user of a smartphone walks out of a vehicle from inside the vehicle while holding the smartphone, Bluetooth (BT) between an audio video navigation telematics (AVNT) system and the smartphone may generally be released to enhance marketability.

[0083] According to the embodiments of the present disclosure, linkage with a user's smartphone located outside a vehicle can be prevented, thereby enhancing the usability of BT.

[0084] Figure 4 It is a diagram for explaining a method for determining a mobile terminal position of a wireless communication linkage control device according to an embodiment of the present disclosure.

[0085] The wireless communication linkage control device according to an embodiment of the present disclosure may apply a weight of a position determination method of a mobile terminal based on state information of a vehicle, and may determine the position determination method of the mobile terminal based on the applied weight.

[0086] like Figure 4 As shown, the controller 130 according to an embodiment of the present disclosure may determine the current location of the mobile terminal based on location determination methods of a plurality of mobile terminals.

[0087] Here, the controller 130 may execute at least one of the following position determination methods: a first position determination method 510 using high-frequency sound technology, a second position determination method 520 using trilateration technology, a third position determination method 530 using fingerprint technology, or a fourth position determination method 540 using the location information of the mobile terminal, and may determine the current location of the mobile terminal.

[0088] For example, in the first position determination method 510 using high-frequency sound technology, it can be determined based on the signal information of the position signal transmitter received from the mobile terminal whether the mobile terminal recognizes the high-frequency sound of the signal received from the position signal transmitter. In this regard, when it is determined that the mobile terminal recognizes the high-frequency sound of the position signal transmitter 120, it can be determined that the current position of the mobile terminal is inside the vehicle, and when it is determined that the mobile terminal does not recognize the high-frequency sound of the position signal transmitter 120, it can be determined that the current position of the mobile terminal is outside the vehicle.

[0089] In another example, in the second position determination method 520 using the trilateration technique, trilateration may be performed based on signal information of the first, second, and third position signal transmitters received from the mobile terminal to calculate the current position of the mobile terminal, and the current position of the mobile terminal may be determined as being inside or outside the vehicle based on the calculated current position of the mobile terminal.

[0090] In another example, in a third location determination method 530 using fingerprint technology, signal strength can be extracted from signal information of a location signal transmitter received from a mobile terminal, the current location of the mobile terminal can be searched from a radio map including signal strength values ​​corresponding to spatial units inside a vehicle based on the extracted signal strength, and the current location of the mobile terminal can be determined as being inside or outside the vehicle based on the retrieved current location of the mobile terminal.

[0091] In another example, in the fourth position determination method 540 using the position information of the mobile terminal, global positioning system (GPS) information including the position information may be received from the mobile terminal, the distance or speed difference between the vehicle and the mobile terminal may be calculated based on the GPS information of the mobile terminal and the GPS information as the position signal of the vehicle, and the current position of the mobile terminal may be determined based on the calculated distance or speed difference.

[0092] Figure 5 Detailed description is a flowchart for explaining a method for controlling wireless communication linkage of a wireless communication linkage control device according to an embodiment of the present disclosure.

[0093] like Figure 5 As shown, according to an embodiment of the present disclosure, the controller may check whether the mobile terminal is in wireless communication linkage (S10).

[0094] Here, the controller may check whether the mobile terminal is in wireless communication linkage via Bluetooth.

[0095] When the mobile terminal is in wireless communication linkage, the controller can obtain the status information of the vehicle (S20).

[0096] Here, the controller may acquire status information of the vehicle, which includes information on opening and closing of vehicle windows and information on a current position of the vehicle.

[0097] Then, the controller may determine a location determination method of the mobile terminal based on the acquired state information of the vehicle ( S30 ).

[0098] Here, the controller may apply a weight of a location determination method of the mobile terminal based on the state information of the vehicle, and may determine the location determination method of the mobile terminal based on the applied weight.

[0099] For example, when applying weights, the controller may apply the weight of a first position determination method using high-frequency sound technology, the weight of a second position determination method using trilateration technology, the weight of a third position determination method using fingerprint technology, and the weight of a fourth position determination method using the location information of the mobile terminal in the position determination method of the mobile terminal.

[0100] When the controller applies the weight, a method of applying the weight of the location determination method of the mobile terminal may be changed according to the state information of the vehicle.

[0101] For example, when the controller applies weights, if the controller determines based on the vehicle's status information that the windows are closed and the vehicle's current location is not in an urban area, the controller may apply the weight of the mobile terminal's location determination method to the first weight application method.

[0102] Here, in the first weight applying method in the location determination method of the mobile terminal, the first weight as the highest weight may be applied to the location determination method using the high-frequency sound technology, a second weight lower than the first weight may be applied to the location determination method using the location information of the mobile terminal, and a third weight lower than the second weight may be applied to each of the location determination method using the trilateral measurement technology and the location determination method using the fingerprint technology.

[0103] In another example, when the controller applies weights, if the controller determines based on the vehicle's status information that the windows are closed and the vehicle's current location is an urban area, the controller may apply the weight of the mobile terminal's location determination method to the second weight application method.

[0104] Here, in the second weight applying method in the location determination method of the mobile terminal, the first weight as the highest weight may be applied to the location determination method using the high-frequency sound technology, a second weight lower than the first weight may be applied to the location determination method using the fingerprint technology, and a third weight lower than the second weight may be applied to each of the location determination method using the trilateral measurement technology and the location determination method using the location information of the mobile terminal.

[0105] In another example, when the controller applies weights, if the controller determines based on the vehicle's status information that the window is open and the vehicle's current location is not in an urban area, the controller may apply the weight of the mobile terminal's location determination method to a third weight application method.

[0106] Here, in the third weight applying method in the location determination method of the mobile terminal, the same weight can be applied to the location determination method using high-frequency sound technology, the location determination method using the location information of the mobile terminal, the location determination method using trilateral measurement technology, and the location determination method using fingerprint technology.

[0107] As another example, when the controller applies weights, if the controller determines from the vehicle's status information that the windows are open and the vehicle's current location is in an urban area, the controller may apply the weight of the mobile terminal's location determination method to a fourth weight application method.

[0108] Here, in the fourth weight applying method in the location determination method of the mobile terminal, the first weight as the highest weight can be applied to the location determination method using the fingerprint technology, the second weight lower than the first weight can be applied to each of the location determination method using the high-frequency sound technology and the location determination method using the trilateral measurement technology, and the third weight lower than the second weight can be applied to the location determination method using the location information of the mobile terminal.

[0109] When determining the location determination method of the mobile terminal, the controller may check the weight of each location determination method applied to the mobile terminal, may select the location determination method to which the highest weight is applied, and may determine the selected location determination method as the location determination method of the mobile terminal.

[0110] Then, the controller may determine the current location of the mobile terminal using the determined location determination method (S40).

[0111] Here, when the determined location determination method is a location determination method using high-frequency sound technology, the controller may determine whether the mobile terminal recognizes the high-frequency sound of the signal received from the location signal transmitter based on the signal information of the location signal transmitter received from the mobile terminal, and in this regard, when it is determined that the mobile terminal recognizes the high-frequency sound of the location signal transmitter, the controller may determine that the current location of the mobile terminal is inside the vehicle, and when it is determined that the mobile terminal does not recognize the high-frequency sound of the location signal transmitter, the controller may determine that the current location of the mobile terminal is outside the vehicle.

[0112] If necessary, when the determined position determination method is a position determination method using trilateration technology, the controller may perform trilateration based on signal information of the first, second and third position signal transmitters received from the mobile terminal to calculate the current position of the mobile terminal, and may determine whether the current position of the mobile terminal is inside or outside the vehicle based on the calculated current position of the mobile terminal.

[0113] In another case, when the determined location determination method is a location determination method using fingerprint technology, the controller may extract signal strength information from signal information of the location signal transmitter received from the mobile terminal, may search for the current location of the mobile terminal from a radio map including signal strength values ​​corresponding to spatial units inside the vehicle based on the extracted signal strength information, and may determine whether the current location of the mobile terminal is inside or outside the vehicle based on the retrieved current location of the mobile terminal.

[0114] In another case, when the determined position determination method is a position determination method using the position information of the mobile terminal, the controller may receive global positioning system (GPS) information including the position information from the mobile terminal, may calculate the distance or speed difference between the vehicle and the mobile terminal based on the GPS information of the mobile terminal and the GPS information as the position signal of the vehicle, and may determine the current position of the mobile terminal based on the calculated distance or speed difference.

[0115] When it is determined that the current location of the mobile terminal is outside the vehicle ( S50 ), the controller may release the wireless communication linkage with the mobile terminal ( S60 ).

[0116] When it is determined that the current location of the mobile terminal is inside the vehicle ( S70 ), the controller may maintain wireless communication linkage with the mobile terminal ( S80 ).

[0117] Then, the controller may check whether there is a request for terminating the process of handling control of wireless communication linkage ( S90 ), and when there is a request for termination, the controller may terminate the process of handling control of wireless communication linkage.

[0118] A method of controlling wireless communication linkage by a wireless communication linkage control device according to another embodiment of the present disclosure will be described.

[0119] The controller according to the present disclosure may receive GPS information including location information from the mobile terminal.

[0120] The controller may then compare the vehicle's location signal with the mobile terminal's GPS information to calculate a distance or speed difference between the mobile terminal and the vehicle.

[0121] Then, when the calculated distance or speed difference is equal to or greater than a threshold value, the controller may determine that the current location of the mobile terminal is outside the vehicle, and may release the wireless communication linkage with the mobile terminal.

[0122] If necessary, the controller can determine whether the mobile terminal recognizes the high-frequency sound of the signal of the position signal transmitter received from the mobile terminal, and when the mobile terminal does not recognize the high-frequency sound of the position signal transmitter or the calculated distance or speed difference is equal to or greater than the threshold, the controller can determine that the current position of the mobile terminal is outside the vehicle and can release the wireless communication linkage with the mobile terminal.

[0123] In another case, the controller may perform trilateral measurement to calculate the current position of the mobile terminal based on information transmitted by the mobile terminal in response to the first, second and third position signals of the position signal transmitter, and when the calculated current position of the mobile terminal corresponds to the outside of the vehicle or the calculated distance or speed difference is equal to or greater than a threshold, the controller may release the wireless communication linkage with the mobile terminal.

[0124] In another example, the controller may extract signal strength information from signal information of a position signal transmitter received from a mobile terminal, may search for the current location of the mobile terminal from a radio map including signal strength values ​​of spatial units corresponding to the interior of a vehicle based on the extracted signal strength, and when the retrieved current location of the mobile terminal corresponds to the outside of the vehicle or the calculated distance or speed difference is equal to or greater than a threshold, the controller may release the wireless communication linkage with the mobile terminal.

[0125] According to an embodiment of the present disclosure, a computer-readable recording medium having recorded thereon a program for executing a method of controlling wireless communication linkage of a wireless communication linkage control device in a vehicle can execute the program provided in the method of controlling wireless communication linkage of a wireless communication linkage control device in a vehicle.

[0127] Another embodiment of the present disclosure may include: a communicator wirelessly linked with a mobile terminal; a position signal receiver for identifying a position of a vehicle; and a controller for controlling the communicator.

[0128] Here, the controller can receive GPS information including location information from the mobile terminal, can compare the vehicle's location signal with the GPS information of the mobile terminal to calculate the distance or speed difference between the mobile terminal and the vehicle, and when the calculated distance or speed difference is equal to or greater than a threshold, the controller can determine that the current location of the mobile terminal is outside the vehicle, and can release the wireless communication linkage with the mobile terminal.

[0129] Another embodiment of the present disclosure may further include a location signal transmitter for transmitting a location signal to the mobile terminal.

[0130] Here, when determining the current position of the mobile terminal, the controller can determine whether the mobile terminal recognizes the high-frequency sound of the signal received from the location information transmitter based on the signal information of the location signal transmitter received from the mobile terminal, and when the mobile terminal does not recognize the high-frequency sound of the location signal transmitter or the calculated distance or speed difference is equal to or greater than the threshold, the controller can determine that the current position of the mobile terminal is outside the vehicle and can release the wireless communication linkage with the mobile terminal.

[0131] Another embodiment of the present disclosure may further include three or more location signal transmitters for sending location signals to the mobile terminal.

[0132] Here, the controller may perform trilateral measurement to calculate the current position of the mobile terminal based on the information sent by the mobile terminal in response to the first, second and third position signal information of the position signal transmitter, and when the calculated current position of the mobile terminal corresponds to the outside of the vehicle or the calculated distance or speed difference is equal to or greater than a threshold, the controller may release the wireless communication linkage with the mobile terminal.

[0133] Another embodiment of the present disclosure may further include a location signal transmitter for transmitting a location signal to the mobile terminal.

[0134] Here, the controller can extract signal strength information from the signal information of the position signal transmitter received from the mobile terminal, and can search the current position of the mobile terminal from a radio map including signal strength values ​​corresponding to the interior space units of the vehicle based on the extracted signal strength, and when the retrieved current position of the mobile terminal corresponds to the outside of the vehicle or the calculated distance or speed difference is equal to or greater than a threshold, the controller can release the wireless communication linkage with the mobile terminal.

[0135] A wireless communication linkage control device according to another embodiment of the present disclosure will be described below.

[0136] Another embodiment of the present disclosure may include: a communicator wirelessly linked to a mobile terminal; a position signal receiver for identifying a position of a vehicle; a position signal transmitter for sending a position signal to the mobile terminal; and a controller for controlling the communicator.

[0137] Here, when the mobile terminal is in wireless communication linkage, the controller can obtain the status information of the vehicle, can determine the location determination method of the mobile terminal based on the acquired status information of the vehicle, can determine the current location determination method of the mobile terminal as the determined location determination method, and can use the determined location determination method to determine the current location of the mobile terminal, and when it is determined that the current location of the mobile terminal is outside the vehicle, the controller can control the communicator to release the wireless communication linkage with the mobile terminal.

[0138] For example, the location signal transmitter may include a Bluetooth Low Energy (BLE) beacon.

[0139] When acquiring the status information of the vehicle, the controller may acquire information about the opening and closing of windows, information about the opening and closing of doors, and information about the current position of the vehicle.

[0140] Here, when the vehicle window or door is open, the controller may determine a method other than the positioning method using high-frequency sound technology as the positioning method, and when the vehicle's GPS signal strength is equal to or less than a threshold, the controller may determine a method other than the positioning method using the location information of the mobile terminal as the positioning method.

[0141] Then, when determining the location determination method of the mobile terminal, the controller may apply a weight of the location determination method of the mobile terminal based on the state information of the vehicle, and may determine the location determination method of the mobile terminal based on the applied weight.

[0142] Here, when applying weights, the controller may apply the weight of a first position determination method using high-frequency sound technology, the weight of a second position determination method using trilateration technology, the weight of a third position determination method using fingerprint technology, and the weight of a fourth position determination method using the position information of the mobile terminal in the position determination method of the mobile terminal.

[0143] When the controller applies the weight, a method of applying the weight of the location determination method of the mobile terminal may be changed according to the state information of the vehicle.

[0144] Here, when the controller applies weights, if the controller determines based on the status information of the vehicle that the window is closed and the current position of the vehicle is not in the urban area, the controller may apply the weight of the mobile terminal's location determination method to the first weight application method, if the controller determines based on the status information of the vehicle that the window is closed and the current position of the vehicle is in the urban area, the controller may apply the weight of the mobile terminal's location determination method to the second weight application method, if the controller determines based on the status information of the vehicle that the window is open and the current position of the vehicle is not in the urban area, the controller may apply the weight of the mobile terminal's location determination method to the third weight application method, and if the controller determines based on the status information of the vehicle that the window is open and the current position of the vehicle is in the urban area, the controller may apply the weight of the mobile terminal's location determination method to the fourth weight application method.

[0145] For example, when the controller applies weights to the first weight application method, if the controller determines based on the vehicle's status information that the windows are closed and the vehicle's current location is not in the urban area, the controller may apply the first weight as the highest weight to the location determination method using high-frequency sound technology in the location determination method of the mobile terminal, may apply a second weight lower than the first weight to the location determination method using the location information of the mobile terminal, and may apply a third weight lower than the second weight to each of the location determination method using the trilateral measurement technology and the location determination method using the fingerprint technology.

[0146] In another example, when the controller applies weights to the second weight application method, if the controller determines based on the vehicle's status information that the windows are closed and the vehicle's current location is in an urban area, the controller may apply a first weight as the highest weight to a location determination method using high-frequency sound technology in the location determination method of the mobile terminal, may apply a second weight lower than the first weight to a location determination method using fingerprint technology, and may apply a third weight lower than the second weight to each of a location determination method using trilateral measurement technology and a location determination method using location information of the mobile terminal.

[0147] In another example, when the controller applies weights to the third weight application method, if the controller determines based on the vehicle's status information that the vehicle's windows are open and the vehicle's current location is not in an urban area, the controller may apply the same weight to each of the positioning methods of the mobile terminal, including a positioning method using high-frequency sound technology, a positioning method using the location information of the mobile terminal, a positioning method using trilateration technology, and a positioning method using fingerprint technology.

[0148] In another example, when the controller applies weights to the fourth weight application method, if the controller determines that the window is open and the current location of the vehicle is in an urban area, the controller may apply the first weight as the highest weight to the location determination method using fingerprint technology in the location determination method of the mobile terminal, may apply a second weight lower than the first weight to each of the location determination method using high-frequency sound technology and the location determination method using trilateration technology, and may apply a third weight lower than the second weight to the location determination method using the location information of the mobile terminal.

[0149] Then, when determining the location determination method of the mobile terminal, the controller may check the weight of each location determination method applied to the mobile terminal, may select the location determination method to which the highest weight is applied, and may determine the selected location determination method as the location determination method of the mobile terminal.

[0150] For example, when the controller determines the current position of the mobile terminal, if the determined position determination method is a position determination method using high-frequency sound technology, the controller can determine whether the mobile terminal recognizes the high-frequency sound of the signal received from the position signal transmitter based on the signal information of the position signal transmitter received from the mobile terminal, and in this regard, when it is determined that the mobile terminal recognizes the high-frequency sound of the position signal transmitter, the controller can determine that the current position of the mobile terminal is inside the vehicle.

[0151] In another example, when the controller determines the current position of the mobile terminal, if the determined position determination method is a position determination method using a trilateration technique, the controller may perform trilateration based on signal information of the first, second, and third position signal transmitters received from the mobile terminal to calculate the current position of the mobile terminal, and may determine whether the current position of the mobile terminal is inside or outside the vehicle based on the calculated current position of the mobile terminal.

[0152] In another example, when the controller determines the current location of the mobile terminal, if the determined location determination method is a location determination method using fingerprint technology, the controller may extract signal strength from signal information of the location signal transmitter received from the mobile terminal, may search for the current location of the mobile terminal from a radio map including signal strength values ​​corresponding to spatial units inside the vehicle based on the extracted signal strength, and may determine whether the current location of the mobile terminal is inside or outside the vehicle based on the retrieved current location of the mobile terminal.

[0153] In another example, when the controller determines the current location of the mobile terminal, if the determined location determination method is a location determination method using location information of the mobile terminal, the controller may receive global positioning system (GPS) information including location information from the mobile terminal, may calculate the distance or speed difference between the vehicle and the mobile terminal based on the GPS information of the mobile terminal and the GPS information as a location signal of the vehicle, and may determine the current location of the mobile terminal based on the calculated distance or speed difference.

[0154] In this way, according to an embodiment of the present disclosure, a location determination method of a mobile terminal can be determined based on the status information of the vehicle to determine the current location of the mobile terminal, so that the maintenance or release of the wireless communication linkage with the mobile terminal can be reliably and optimally controlled according to the location of the mobile terminal.

[0155] For example, when a user of a smartphone walks out of a vehicle from inside the vehicle while holding the smartphone, Bluetooth (BT) between an audio video navigation telematics (AVNT) system and the smartphone may generally be released to enhance marketability.

[0156] According to the embodiments of the present disclosure, linkage with a user's smartphone located outside a vehicle can be prevented, thereby enhancing the usability of BT.

[0157] According to the wireless communication linkage control device and wireless communication linkage control method in a vehicle configured as above and related to at least one embodiment of the present disclosure, a location determination method of the mobile terminal can be determined based on the status information of the vehicle to determine the current location of the mobile terminal, so that the maintenance or release of the wireless communication linkage with the mobile terminal can be reliably and optimally controlled according to the location of the mobile terminal.

[0158] For example, when a user of a smartphone walks out of a vehicle while holding the smartphone, Bluetooth (BT) between an audio video navigation telematics (AVNT) system and the smartphone may generally be released to enhance marketability.
