Description

  The present invention relates to an in-vehicle device that is mounted on a vehicle and provides various service functions to a driver, and a control method thereof.

  Mounted on the vehicle, on the vehicle, provides the driver with various map information and various information attached to the map, various directions such as guidance to the destination, operation of the air conditioner, radio, music player, video display of the in-vehicle camera, etc. In-vehicle devices (such as a car navigation device, an air conditioner operation device, a car audio device, and a back monitor device) that provide a service function are generally used. In recent years, there is a highly functional mobile phone (smart phone) based on a personal computer. And it is becoming possible to provide a user with a service equivalent to an in-vehicle device to a user with a mobile phone. For example, it is possible to connect the in-vehicle device and the mobile phone by wire or wireless, and display the mobile phone application screen on the in-vehicle device, or the user can control the application on the mobile phone by operating the in-vehicle device. It is becoming.

  The abstract of Patent Document 1 discloses a remote control system for controlling a remote control target terminal from a control instruction terminal. By using the technique disclosed in Patent Document 1, it becomes possible to use an application of a mobile phone (remote control target terminal) on a large screen of a vehicle-mounted device (control instruction terminal) suitable for use in a vehicle. . In addition, for example, the screens of various terminal devices such as mobile phones can be integrated and displayed on the in-vehicle device.

  By the way, generally, since the vehicle-mounted device is provided in the vehicle and integrated with the vehicle, the frequency of updating internal data and programs is low. For example, in-vehicle devices often do not update internal data and programs very frequently and can continue to be used for a long period of 7 to 10 years. Although it is possible to update the program of the in-vehicle device at the automobile dealer, it is necessary for the user to bring the vehicle equipped with the in-vehicle device to the dealer, which is troublesome.

  In comparison, mobile phones are often replaced in about two years, and old devices are relatively rarely used for a long time. In addition, mobile phones with advanced functions are often connected to a network at all times, and it is easy to acquire and update information and programs from the server, so that new information and new functions are always available. There are many cases.

JP 2010-44458 A

  If a mobile phone application can be used from an in-vehicle device, it is convenient because a large screen can be used, but there are the following problems.

  The driver needs to keep an eye on the front of the vehicle while driving and must avoid gazing at the screen of the in-vehicle device for a long time. Especially when the vehicle's running speed is fast, the distance that the vehicle moves in a certain time becomes longer and the driver's field of view becomes narrow, so it is very dangerous for the driver to remove his line of sight from the front view for a long time. .

  However, a general mobile phone application designed for general use without assuming that the driver uses the vehicle while driving may be unsuitable for the driver to use the vehicle-mounted device. For this reason, when using a mobile phone application in an in-vehicle device, it may be difficult to visually recognize or operate the screen, and the time for the driver to remove his / her line of sight from the front view may be long.

  In particular, when a screen that is likely to be watched by the user, including operation buttons, small characters, moving images, etc., is displayed on the in-vehicle device, the driver's attention is directed to the in-vehicle device and the attention to the outside world is reduced. Cheap. In addition, even when a plurality of operations are required until the application transitions to a desired state, the driver's attention is directed to the in-vehicle device, and the attention to the outside world is likely to be reduced.

Implement the restriction process.

  According to the present embodiment, when various applications for mobile phones are used in the in-vehicle device 10, display and operation can be limited so as to be suitable for use in the in-vehicle device 10.

  Furthermore, in this embodiment, when the communication control unit 13 is connected to the mobile phone 19, the communication control unit 13 notifies the mobile phone 19 of identification information for identifying the model of the vehicle-mounted device 10 itself, and the application running on the mobile phone 19 First input / output restriction information corresponding to the combination with the in-vehicle device is acquired from the mobile phone 19 and recorded in the input / output restriction information storage unit 16.

  At that time, if the mobile phone 19 holds the first input / output restriction information for the combination of the application running on the mobile phone 19 itself and the in-vehicle device 10, the mobile phone 19 transmits it to the in-vehicle device 10. . In addition, if the mobile phone 19 does not hold the first input / output restriction information for the combination of the application running on itself and the in-vehicle device 10, the mobile phone 19 obtains it from the server (not shown) and stores it in the in-vehicle device 10. Notice. According to this, even if the application on the mobile phone 19 is not updated, the restriction information on the new combination of the application and the vehicle-mounted device 10 can be notified to the vehicle-mounted device 10 later.

  In the present embodiment, an example in which an application running on a mobile phone is displayed and operated on the in-vehicle device 10 has been described. However, in the present invention, the terminal device connected to the in-vehicle device 10 may not be a mobile phone. The terminal device connected to the in-vehicle device 10 may be an information processing device provided with a communication interface.

  In the row 415, when the selected “part” is “all input”, the “restricted area” is “all screen area, all keys”, the “display restriction method” is “none”, and the “composite data” is It is a description that it is “none”.

  For example, when the vehicle state determination unit 206 extracts “display part A” and restricts the display of “display part A”, when the row 405 is read, the “restricted area” becomes “rectangular area (x1, y1) − (x2 , Y2) ”, the“ restriction method ”is“ superposition ”, and the“ composite data used for superposition is “image data A” ”. “Rectangular area (x1, y1) − (x2, y2)” represents a rectangular area having coordinates (x1, y1) and coordinates (x2, y2) of the mobile phone as diagonal vertices. In this case, the vehicle state determination unit 206 instructs the output restriction unit 205 to display “image data A” superimposed on “rectangular region (x1, y1) − (x2, y2)” of the display of the mobile phone 103. The display of the mobile phone 103 on the display device 111 of the in-vehicle device 101 is restricted.

  When the display of “display part B” is restricted, when the rows 406 and 407 are read, the “restricted region” is “rectangular region (x3, y3) − (x4, y4)” and “rectangular region (x5, y5)”. − (X6, y6) ”. The “restricted display method” of “rectangular area (x3, y3) − (x4, y4)” is “superposition”, “composite data” is “image data B”, and “rectangular area (x5, y5)-( The “restricted display method” of “x6, y6)” is “superposition”, and the “composite data” is “gray”.

  When the display of the “display part C” is restricted, when the row 408 is read, the “restricted region” is “rectangular region (x7, y7) − (x8, y8)”, the “restricted display method” is “superposition”, “Synthetic data” is “gray”. In this case, a “gray” rectangle is superimposed on the “rectangular region (x7, y7) − (x8, y8)” in the display of the mobile phone 103, and the display of the mobile phone 103 on the display device 111 of the in-vehicle device 101 is displayed. Limit.

  When the input of “input part a” is restricted, when row 409 is read, “restricted region” is “rectangular region (x5, y5) − (x6, y6)”. In this case, the vehicle state determination unit 206 instructs the input restriction unit 204 not to output the input to “rectangular region (x5, y5) − (x6, y6)” to the in-vehicle device in-vehicle communication control unit 209.

  When the input of the “input part b” is restricted, when the rows 410 and 411 are read, the “restricted region” is “rectangular region (x7, y7) − (x8, y8)” and “selection key”. In this case, the vehicle state determination unit 206 does not output the input of the “rectangular region (x7, y7) − (x8, y8)” and the “selection key” to the input restriction unit 204 to the in-vehicle communication control unit 209. To instruct.

  When display restriction of “full screen A” is performed, when line 412 is read, “restricted area” is “full screen area”, “restricted display method” is “reduced 1/5 display”, and “reduced 1/5 on-vehicle use”. “The machine screen and a 1/5 reduced mobile phone screen”. “Reduced 1/5 display” is to reduce the entire display of the mobile phone 103 to 1/5 and display it superimposed on the screen of the in-vehicle device. In this case, the vehicle state determination unit 206 processes the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for reduction 1/5 with respect to the in-vehicle device input / output switching unit 202 and receives it from the in-vehicle device in-vehicle communication control unit 209. The display data of the mobile phone 103 is reduced to 1/5 and an instruction is given to pass it to the output restriction unit 205, and the mobile phone reduced to 1/5 received from the in-vehicle device input / output switching unit 202 to the output restriction unit 205 The display data of 103 is superposed on the display data of the in-vehicle device application unit 201 that has been processed into the on-vehicle device screen for reduction 1/5, and is instructed to be passed to the in-vehicle device display control unit 208 for display.

  When restricting the display of “full screen B”, row 413 is read, “restricted area” is set to “full screen area”, “restricted display method” is set to “icon display”, and “composite data” is set to “on-vehicle screen for icons” And icon data. “Icon display” is to superimpose the “icon data” of the application executed on the mobile phone 103 on the screen of the in-vehicle device without displaying the mobile phone 103. In this case, the vehicle state determination unit 206 passes icon data to the in-vehicle device input / output switching unit 202, processes the display data of the in-vehicle device application unit 201 into an icon on-vehicle device screen, and outputs the icon data together with the icon data. To the output restriction unit 205, the icon data is superimposed on the display data of the in-vehicle device application unit 201 processed into the in-vehicle device screen for icons received from the in-vehicle device input / output switching unit 202. Instructs the control unit 208 to display the information.

  When restricting the display of “full screen C”, when row 414 is read, “restricted area” is “full screen area”, “restricted display method” is “on-vehicle device full-screen display”, and “composite data” is “on-vehicle”. Machine screen ". “In-vehicle device full screen display” is to display the screen of the application executed on the mobile phone 103 without displaying the mobile phone 103. In this case, the vehicle state determination unit 206 instructs the in-vehicle device input / output switching unit 202 to pass the display data of the in-vehicle device application unit 201 to the output restriction unit 205, and instructs the output restriction unit 205 to perform the in-vehicle device input / output. The display data of the in-vehicle device application unit 201 received from the switching unit 202 is given to the in-vehicle device display control unit 208 to be displayed.

  When “all input” is restricted, line 415 is read and “restricted area” is set to “all screen area and all keys”. In this case, the vehicle state determination unit 206 instructs the input restriction unit 204 not to output all inputs to the in-vehicle device in-vehicle communication control unit 209.

  FIG. 6 is an example of a screen on which display and operation are restricted when a mobile phone application is remotely controlled by an in-vehicle device.

  Reference numeral 501 is an example of a screen of an application when the parking brake is applied and the vehicle speed is 0 km / h. Reference numeral 502 is an example of an application screen when the parking brake is not applied and the vehicle speed is 0 km / h. Reference numeral 503 is an example of an application screen when the parking brake is not applied and the vehicle speed exceeds 0 km / h and is 20 km / h or less. Reference numeral 504 is an example of an application screen when the parking brake is not applied and the vehicle speed exceeds 20 km / h and is equal to or less than 30 km / h.

Reference numeral 506 is an example of an application screen when the parking brake is not applied and the vehicle speed exceeds 40 km / h and is 50 km / h or less. Reference numeral 507 is an example of an application screen when the parking brake is not applied and the vehicle speed exceeds 50 km / h.

  Reference numeral 508 denotes a full screen area of the display device 111 included in the in-vehicle device 101. Reference numeral 509 is a selection key of the input device 110 provided in the in-vehicle device 101. Reference numeral 510 is a return key of the input device 110 provided in the in-vehicle device 101. Reference numeral 511 denotes a rectangular region (x1, y1)-(x2, y2) of the display device 111 included in the in-vehicle device 101. Reference numeral 512 denotes a rectangular region (x3, y3)-(x4, y4) of the display device 111 included in the in-vehicle device 101. Reference numeral 513 denotes a rectangular area (x5, y5)-(x6, y6) of the display device 111 included in the in-vehicle device 101. Reference numeral 514 denotes a rectangular area (x7, y7)-(x8, y8) of the display device 111 included in the in-vehicle device 101. Reference numeral 515 denotes a display area of a mobile phone screen with a reduction of 1/5 of the display device 111 included in the in-vehicle device 101. Reference numeral 516 denotes a display area of a mobile phone application icon of the display device 111 provided in the in-vehicle device 101.

  When the parking brake is applied and the vehicle speed is 0 km / h, the vehicle state determination unit 206 satisfies the condition of only the row 305 in the table of FIG. "None" is taken out for "operation restriction sites". Since the “display restriction part” is “none”, the vehicle state determination unit 206 passes the input received from the in-vehicle device input control unit 207 to the in-vehicle device input / output switching unit 202 as it is to the input restriction unit 204, An instruction is given to pass the display data of the mobile phone 103 received from the in-vehicle communication control unit 209 to the output limiting unit 205 as it is, and the input received from the in-vehicle unit input / output switching unit 202 is directly input to the input limiting unit 204 as it is. The mobile phone 103 is instructed to be passed to the mobile phone 103 via the unit 209, and the mobile phone 103 display data received from the in-vehicle device input / output switching unit 202 is passed to the output restricting unit 205 as it is to the in-vehicle device display control unit 208. Instruct the device 111 to display. For this reason, when the parking brake is applied and the vehicle speed is 0 km / h, the screen of the screen example 501 is the same display as the screen of the mobile phone application unit 210 of the mobile phone 103, and operations on any area of the screen can be carried Called to phone 103.

  When the parking brake is not applied and the vehicle speed is 0 km / h, the vehicle state determination unit 206 satisfies the condition of only the row 306 in the table of FIG. “Display part A” and “None” for “operation restriction part” are taken out. Then, a row 405 in which “part” is “display part A” is extracted from the table of FIG. 5, and “restricted area” is “rectangular area (x1, y1) − (x2, y2)” and “restriction method”. "Is" superposition ", and" composite data used for superposition is "image data A". “Rectangular area (x1, y1) − (x2, y2)” represents a rectangular area having coordinates (x1, y1) and coordinates (x2, y2) on the screen of the mobile phone 103 as diagonal vertices. In this case, the vehicle state determination unit 206 instructs the output restriction unit 205 to display “image data A” superimposed on “rectangular area (x1, y1) − (x2, y2)” on the screen of the mobile phone 103. By doing so, the display of the mobile phone 103 on the display device 111 of the in-vehicle device 101 is restricted. Therefore, an example screen 502 when the parking brake is not applied and the vehicle speed is 0 km / h is a rectangular area (x1, y1) − (x2, y2) Image data A is displayed at 511. However, an operation for any area of the screen is transmitted to the mobile phone 103.

  When the parking brake is not applied and the vehicle speed exceeds 0 km / h and is not more than 20 km / h, the vehicle state determination unit 206 satisfies the conditions of the rows 306 and 307 in the table of FIG. From “4”, “display restricted area” is “display area A” and “display area B”, and “operation restricted area” is “none” and “input area a”. Then, rows 405, 406, 407, and 409 in which “part” is “display part A”, “display part B”, and “input part a” are extracted from the table of FIG. Then, the vehicle state determination unit 206 includes a rectangular area (x1, y1)-(x2, y2) 511, a rectangular area (x3, y3)-(x4, y4) 512, a rectangular area (x5, y5)-(x6, y6) Instructing the output restriction unit 205 to restrict the display of 513. Further, the vehicle state determination unit 206 instructs the input restriction unit 204 to restrict the input of the rectangular area (x5, y5) − (x6, y6) 513. For this reason, the screen example 503 in the case where the parking brake is not applied and the vehicle speed exceeds 0 km / h and is equal to or less than 20 km / h is a rectangular area (x1) in the display of the mobile phone application unit 210 of the mobile phone 103. , Y1)-(x2, y2) 511, the image data A is displayed, the image data B is displayed in the rectangular area (x3, y3)-(x4, y4) 512, and the rectangular area (x5, y5)-(x6). , Y6) 513, a gray rectangle is displayed, and the input to the rectangular area (x5, y5)-(x6, y6) 513 is not transmitted to the mobile phone 103.

  When the parking brake is not applied and the vehicle speed exceeds 20 km / h and is 30 km / h or less, the vehicle state determination unit 206 satisfies the conditions of the rows 306, 307, and 308 in the table of FIG. From the table of FIG. 4, “display restriction part” is “display part A”, “display part B” and “display part C”, and “operation restriction part” is “none”, “input part a” and “input part” b "is removed. Further, from the table of FIG. 5, rows 405 and 406 in which “part” is “display part A”, “display part B”, “display part C”, “input part a”, and “input part b”. , Line 407, line 408, line 409, line 410, and line 411 are taken out. Then, the vehicle state determination unit 206 includes a rectangular area (x1, y1)-(x2, y2) 511, a rectangular area (x3, y3)-(x4, y4) 512, a rectangular area (x5, y5)-(x6, The output restriction unit 205 is instructed to restrict the display of y6) 513 and rectangular area (x7, y7)-(x8, y8) 514, and the rectangular area (x5, y5)-(x6, y6) 513, rectangular area (x7, y7)-(x8, y8) 514, the input restriction unit 204 is instructed to restrict the input of the selection key. For this reason, the screen example 504 when the parking brake is not applied and the vehicle speed exceeds 20 km / h and is 30 km / h or less is a rectangular area (x1 in the display of the mobile phone application unit 210 of the mobile phone 103. , Y1)-(x2, y2) 511, the image data A is displayed, the image data B is displayed in the rectangular area (x3, y3)-(x4, y4) 512, and the rectangular area (x5, y5)-(x6). , Y6) 513, a gray rectangle is displayed, a rectangular area (x7, y7)-(x8, y8) 514 is displayed as a gray rectangle, a rectangular area (x5, y5)-(x6, y6) 513, a rectangle Input to the area (x7, y7)-(x8, y8) 514, the selection key is not transmitted to the mobile phone 103.

  When the parking brake is not applied and the vehicle speed exceeds 30 km / h and is 40 km / h or less, the vehicle state determination unit 206 satisfies only the condition of the row 309 in the table of FIG. From the table, “display restriction part” is “full screen A”, and “operation restriction part” is “all input”. Further, from the table of FIG. 5, the rows 412 and 415 in which “part” is “full screen A” and “all inputs” are extracted. Then, the vehicle state determination unit 206 processes the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for reduction 1/5 to the in-vehicle device input / output switching unit 202 and receives it from the in-vehicle device in-vehicle communication control unit 209. The display data of the mobile phone 103 is reduced to 1/5 and an instruction is given to pass it to the output restriction unit 205, and the mobile phone reduced to 1/5 received from the in-vehicle device input / output switching unit 202 to the output restriction unit 205 The display data of 103 is superposed on the display data of the in-vehicle device application unit 201 that has been processed into the in-vehicle device screen for reduction 1/5, and is instructed to be passed to the in-vehicle device display control unit 208 for display. Instructing not to output all inputs to the in-vehicle communication control unit 209. For this reason, in the example 505 of the screen when the parking brake is not applied and the vehicle speed exceeds 30 km / h and is 40 km / h or less, the entire screen area 508 of the display device 111 of the in-vehicle device 101 is reduced to 1/5. The display data of the mobile phone 103 reduced to 1/5 is displayed in the display area 515 of the mobile phone screen reduced to 1/5, and all inputs are transmitted to the mobile phone 103. Disappear.

  When the parking brake is not applied and the vehicle speed exceeds 40 km / h and is 50 km / h or less, the vehicle state determination unit 206 satisfies only the condition of the row 310 in the table of FIG. From the table, “display restriction part” is “full screen B”, and “operation restriction part” is “all input”. Further, from the table of FIG. 5, the rows 413 and 415 in which “part” is “full screen B” and “all inputs” are extracted. Then, the vehicle state determination unit 206 passes icon data to the in-vehicle device input / output switching unit 202, processes the display data of the in-vehicle device application unit 201 into an in-vehicle device screen for icons, and outputs it to the output restriction unit 205 together with the icon data. The in-vehicle device display control is performed by superimposing the icon data on the display data of the in-vehicle device application unit 201 processed into the icon on-vehicle device screen received from the in-vehicle device input / output switching unit 202 to the output restriction unit 205. The instruction is given to the unit 208 for display, and the input restriction unit 204 is instructed not to output all inputs to the in-vehicle communication control unit 209. For this reason, in the example 506 of the screen when the parking brake is not applied and the vehicle speed exceeds 40 km / h and is equal to or less than 50 km / h, the on-vehicle device for icons is displayed in the full screen area 508 of the display device 111 of the on-vehicle device 101. A screen is displayed, and an icon is displayed in the display area 516 of the mobile phone application icon, and all inputs cannot be transmitted to the mobile phone 103.

  When the parking brake is not applied and the vehicle speed exceeds 50 km / h, the vehicle state determination unit 206 satisfies the condition of only the row 311 of the table of FIG. “Parts” is “Full Screen C”, and “Operation Restriction Part” is “All Inputs”. Further, the vehicle state determination unit 206 takes out the rows 414 and 415 in which “part” is “full screen C” and “all inputs” from the table of FIG. Then, the vehicle state determination unit 206 instructs the in-vehicle device input / output switching unit 202 to pass the display data of the in-vehicle device application unit 201 to the output restriction unit 205, and instructs the output restriction unit 205 to perform in-vehicle device input / output switching. The display data of the in-vehicle device application unit 201 received from the unit 202 is instructed to be passed to the in-vehicle device display control unit 208 for display, and all inputs are output to the in-vehicle device in-vehicle communication control unit 209. Instruct not to. For this reason, in the example 507 of the screen when the parking brake is not applied and the vehicle speed exceeds 50 km / h, the in-vehicle device screen is displayed in the full screen area 508 of the display device 111 of the in-vehicle device 101. Is not transmitted to the mobile phone 103.

  FIG. 7 is a diagram illustrating an example of a table for managing display and operation restriction conditions according to a predetermined vehicle state. The configuration is the same as the restriction condition information table of FIG. The description of the portions having the same functions as those in the configuration denoted by the same reference numerals shown in FIG.
