## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
Japan Priority Application 2012-078637, filed Mar. 30, 2012 including the specification, drawings, claims and abstract, is incorporated herein by reference in its entirety. This application is a Continuation of U.S. application Ser. No. 13/764,381, filed Feb. 11, 2013, incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an in-vehicle device that is installed in a vehicle, and provides a driver with various service functions, and a control method thereof.
2. Description of the Related Art
In-vehicle devices (car navigation devices, air conditioner operation devices, car audio devices, back monitor devices, and the like) that are installed in vehicles, provide drivers with various information associated with map information or maps in the vehicles, and provide the drivers with various service functions such as navigation to a destination, operation of an air conditioner, a radio, or a music player, image display of an in-vehicle camera are generally utilized. Recently, mobile phones (smart phones) developed based on personal computers and having high functionality are utilized. It is becoming possible for the mobile phones to provide users with services equivalent to those of the in-vehicle devices. For example, it is becoming possible that the in-vehicle device and the mobile phone are connected in a wired or wireless manner, and a screen of an application of the mobile phone is displayed on the in-vehicle device, or a user operates the in-vehicle device to control the application on the mobile phone.
In the abstract of Japanese Patent Application Laid-open No. 2010-44458, a remote-control system that controls a remote-control target terminal from a control instruction terminal is disclosed. By utilizing the technique disclosed in Japanese Patent Application Laid-open No. 2010-44458, it becomes possible to utilize an application of a mobile phone (remote-control target terminal) with a large screen of an in-vehicle device (control instruction terminal) suitable for utilization in a vehicle. Additionally, it becomes also possible to integrate screens of various terminal devices such as the mobile phone and to display the screens on the in-vehicle device, for example.
Generally, since the in-vehicle device is mounted on the vehicle, and integrated with the vehicle, a frequency of update of internal data or a program is low. For example, the internal data or the program of the in-vehicle device is not relatively frequently updated, and is often continued to be used for a long period of time, such as seven to ten years. Although the program of the in-vehicle device can be updated at an automobile dealer, a user needs to bring the vehicle with the in-vehicle device installed therein all the way into the dealer, which is troublesome.
As compared with this, the mobile phone is often replaced around every two years, and an old mobile phone is not often continued to be used over a long period of time. Additionally, since the mobile phone with high functionality is often always connected to a network, and easily updated by acquiring information or a program from a server, the mobile phone is often maintained in a state where new information and new functions can be always utilized.
If an application of a mobile phone can be utilized from an in-vehicle device, it is convenient because a large screen can be used. However, there are the following problems.
A driver needs to direct his attention to the front of a vehicle at every moment while the vehicle is moving, and has to avoid watching of the screen of the in-vehicle device for a long time. Particularly, in a case where the vehicle moves at a high speed, since a moving distance of the vehicle for a constant time is long, and a visual field of the driver becomes narrow, it is extremely dangerous that the driver removes his gaze from the view of the front of the vehicle for a long time.
However, general applications of the mobile phone, which are designed for general purposes without assuming utilization of the driver during driving, may not be adequate to be utilized with the in-vehicle device by the driver. Therefore, in a case where the applications of the mobile phone are utilized with the in-vehicle device, a screen is difficult to be visually recognized, or the applications are difficult to be operated, and hence the time for removing the driver's gaze from the view of the front of the vehicle may tend to be increased.
Particularly, for example, when a screen including operation buttons, small characters, moving images, and the like, at which a user tends to fixedly look, is displayed on the in-vehicle device, the attention of the driver directs to the in-vehicle device, and attentiveness to the outside world tends to be decreased. Additionally, also in a case where operation is required a plurality of times until the application is changed to a desired state, the attention of the driver directs to the in-vehicle device, and attentiveness to the outside world tends to be decreased.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a technique enabling limitation of display or operation for safely utilizing, on an in-vehicle device, an application on a terminal device, in a case of utilization of the application on the in-vehicle device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Basic embodiment of the present invention will be now described.
FIG. 1 is a block diagram showing a remote control system according to the present embodiment. The remote control system according to the present embodiment has an in-vehicle device 10 and a mobile phone 19.
The mobile phone 19 is a highly functional mobile phone terminal that runs an application and provides a user with a service function.
The in-vehicle device 10 is a device such as a navigation device, an air conditioner operation device, a car audio device, and a back monitor device, which is installed in a vehicle such as an automobile, is connected to the mobile phone 19 in a wired or wireless manner, and is capable of operating and displaying the application running on the mobile phone 19.
The in-vehicle device 10 has an input control unit 11, an output control unit 12, a communication control unit 13, a determination unit 14, a limitation unit 15, and an input/output limitation information storage unit 16.
The input control unit 11 detects operation input by touch operation to a touch panel or pressing of an operation button.
The output control unit 12 controls display output of an application screen to a liquid crystal display or the like.
The communication control unit 13 is connected to the mobile phone 19, receives display output from the mobile phone 19, and transmits operation input to the mobile phone 19.
The input/output limitation information storage unit 16 stores input/output limitation information, in which limitation processing to input/output to the application, which is running on the mobile phone 19, by the in-vehicle device 10 is prescribed by association with the application.
While the applications running on the mobile phone 19 are basically designed on the assumption of display and operation with the mobile phone 19, in the remote control system according to the present embodiment, the applications are displayed and operated with the in-vehicle device 10. The in-vehicle device 10 generally has a larger screen than that of the mobile phone 19, and therefore is convenient as long as the user does not drive and only utilizes the application.
However, it is dangerous that the user operates the in-vehicle device 10 while driving a vehicle. According to the present embodiment, at least a part of the applications is applied to the limitation processing associated with the application, and the application screen is not displayed on the in-vehicle device 10, or operation from the in-vehicle device 10 is not accepted. For example, while the vehicle is moving, video contents are not displayed on the in-vehicle device 10, or operation buttons become inactivated.
The input/output limitation information includes first input/output limitation information, in which the limitation processing with respect to a combination of the application and the in-vehicle device 10 is prescribed, and second input/output limitation information to be applied to the combination of the application and the in-vehicle device 10, which is not prescribed in the first input/output limitation information.
In the first input/output limitation information, such limitation processing as not to limit operation or display as much as possible while ensuring safety of driving, and as to enhance convenience is prescribed as dedicated information with respect to the combination of the application and the in-vehicle device 10. On the other hand, the second input/output limitation information is applied to the combination of the application and the in-vehicle device 10, which is not prescribed in the first input/output limitation information, for general purposes, and therefore such limitation processing as to ensure safety with respect to various combinations even when operation or display is strictly limited is prescribed.
The determination unit 14 acquires a vehicle state of the vehicle, and determines limitation processing, which is applied to operation input to the application and display output from the application, on the basis of the application running on the mobile phone 19, the vehicle state, and the input/output limitation information.
At this time, when the combination of the application running on the mobile phone 19 and the in-vehicle device 10 itself is prescribed in the first input/output limitation information, the determination unit 14 determines the limitation processing to the application on the basis of the first input/output limitation information. When the combination of the application and the in-vehicle device 10 itself is not prescribed in the first input/output limitation information, the determination unit 14 determines the limitation processing to the application on the basis of the second input/output limitation information.
The limitation unit 15 performs the limitation processing determined by the determination unit 14 for operation input detected by the input control unit 11 and transmitted to the communication control unit 13, and display output received by the communication control unit 13 and transmitted to the output control unit 12.
According to the present embodiment, display or operation can be limited so as to be suitable for utilization in the in-vehicle device 10 in a case where various applications for the mobile phone are utilized with the in-vehicle device 10.
Furthermore, according to the present 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 identifying a model of the in-vehicle device 10 itself, acquires, from the mobile phone 19, first input/output limitation information corresponding to the combination of the application running on the mobile phone 19 and the in-vehicle device, and records the same in the input/output limitation information storage unit 16.
At this time, when the mobile phone 19 holds the first input/output limitation information for the combination of the application running on the mobile phone 19 itself and the in-vehicle device 10 by itself, the mobile phone 19 transmits the same to the in-vehicle device 10. When the mobile phone 19 does not hold the first input/output limitation information for the combination of the application running on the mobile phone 19 itself and the in-vehicle device 10 by itself, the mobile phone 19 acquires the same from a server (not shown), and notifies the in-vehicle device 10 of the same. According to this, even when the application on the mobile phone 19 is not updated, limitation information for a new combination of the application and the in-vehicle device 10 can be notified to the in-vehicle device 10 even afterwards.
According to the present embodiment, while an example of displaying and operating the application running on the mobile phone with the in-vehicle device 10 is shown, a terminal device connected to the in-vehicle device 10 in the present invention may not be the mobile phone. As the terminal device connected to the in-vehicle device 10, any information processing device including a communication interface may be employed. As another example, a personal computer or a game machine having a wireless LAN interface or a USB interface may be employed.
Examples of the vehicle according to the present embodiment widely include vehicles for movement such as automobiles, motorcycles, and bicycles.

The mobile phone vehicle-exterior communication control unit 215 controls the vehicle exterior communication IF 119 of the mobile phone 103 in accordance with the instruction of the mobile phone application unit 210, and controls communication with the server 105 through the network 104.
The delivery unit 222 of the server 105 specifies input/output limitation information suitable for a combination of the in-vehicle device 101 instructing operation remotely and the mobile phone 103 receiving and performing the remote operation in reference to the input/output limitation information management table 223 from the in-vehicle device model ID and the mobile phone app ID received from the mobile phone 103, and passes the same to the mobile phone 103.
The input/output limitation information management table 223 is a table illustrated in FIG. 9, and the input/output limitation information suitable for the combination is stored for each combination of the in-vehicle device model ID and the mobile phone app ID.
FIG. 4 is a figure showing a table of the limitation condition information. This is a table for managing the display limitation part and the operation limitation part on the screen for each state of the vehicle installed with in-vehicle device 101 therein. In this example, as the state of the vehicle, the parking brake state and the vehicle speed are utilized.
In a “parking brake state” 301, the parking brake state acquired by the vehicle state sensor 102 is listed.
In a “vehicle speed” 302, the vehicle speed acquired by the vehicle state sensor 102 is listed.
In a “display limitation part” 303, the ID of the display limitation part is listed.
In an “operation limitation part” 304, the ID of the operation limitation part is listed.
On a line 305, it is described that in a case where the “parking brake state” is “ON”, and the “vehicle speed” is “vehicle speed=0 km/h”, the “display limitation part” is “none”, and the “operation limitation part” is “none”. On a line 306, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “0 km/h≦vehicle speed≦30 km/h”, the “display limitation part” is a “display part A”, and the “operation limitation part” is “none”. On a line 307, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “0 km/h<vehicle speed≦30 km/h”, the “display limitation part” is a “display part B”, and the “operation limitation part” is an “input part a”. On a line 308, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “20 km/h<vehicle speed≦30 km/h”, the “display limitation part” is a “display part C”, and the “operation limitation part” is an “input part b”. On a line 309, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “30 km/h<vehicle speed≦40 km/h”, the “display limitation part” is a “full screen A”, and the “operation limitation part” is “all input”. On a line 310, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “40 km/h<vehicle speed≦50 km/h”, the “display limitation part” is a “full screen B”, the “operation limitation part” is “all input”. On a line 311, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “50 km/h<vehicle speed”, the “display limitation part” is a “full screen C”, and the “operation limitation part” is “all input”.
The vehicle state determination unit 206 receives this table from the input/output limitation information region 221 of the input/output limitation information storage unit 203. Furthermore, the vehicle state determination unit 206 compares the “parking brake state” and the “vehicle speed” received from the vehicle state sensor 102 with conditions of the “parking brake state” and the “vehicle speed” of each line of this table, and extracts the “display limitation part” and the “operation limitation part” of a line meeting the conditions of the vehicle state.
For example, in a case where the “parking brake state” is “ON”, and the “vehicle speed” is “vehicle speed=0 km/h”, the vehicle states meet only the conditions of the line 305. Therefore, the vehicle state determination unit 206 extracts the information that the “display limitation part” is “none”, and the “operation limitation part” is “none”.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “vehicle speed=0 km/h”, the vehicle states meet only the conditions of the line 306. Therefore, the information that the “display limitation part” is the “display part A”, and the “operation limitation part” is “none” is extracted.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “0 km/h<vehicle speed=20 km/h”, the vehicle states meet the conditions of the line 306 and the line 307, and the information that the “display limitation part” is the “display part A” and the “display part B”, and the “operation limitation part” is “none” and the “input part a” is extracted.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “20 km/h<vehicle speed=30 km/h”, the vehicle states meet the conditions of the line 306, and the line 307 and the line 308, the information that the “display limitation part” is the “display part A”, the “display part B” and the “display part C”, and the “operation limitation part” is “none”, the “input part a” and the “input part b” is extracted.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “30 km/h<vehicle speed=40 km/h”, the vehicle states meet only the conditions of the line 309, and the information that the “display limitation part” is the “full screen A”, and the “operation limitation part” is “all input” is extracted.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “40 km/h<vehicle speed=50 km/h”, the vehicle states meet only the conditions of the line 310, and the information that the “display limitation part” is the “full screen B”, and the “operation limitation part” is “all input” is extracted.
In a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “50 km/h<vehicle speed”, the vehicle states meet only the conditions of the line 311, and the information that the “display limitation part” is the “full screen C”, and the “operation limitation part” is “all input” is extracted.

On a line 410, it is described that in a case where the selected “part” is the “input part b”, the “limitation region” is a “rectangular region (x7, y7)-(x8, y8)”, the “limitation display method” is “none”, and the “synthetic data” is “none”.
On a line 411, it is described that in a case where the selected “part” is the “input part b”, the “limitation region” is a “selection key”, the “limitation display method” is “none”, and the “synthetic data” is “none”.
On a line 412, it is described that in a case where the selected “part” is the “full screen A”, the “limitation region” is a “full screen region”, the “limitation display method” is “reduced size 1⁄5 display”, and the “synthetic data” is an “in-vehicle device screen for reduced size 1⁄5 and mobile phone screen for reduced size 1⁄5”.
On a line 413, it is described that in a case where the selected “part” is the “full screen B”, the “limitation region” is a “full screen region”, the “limitation display method” is “icon display”, and the “synthetic data” is an “in-vehicle device screen for icon and icon data”.
On a line 414, it is described that in a case where the selected “part” is the “full screen C”, the “limitation region” is the “full screen region”, the “limitation display method” is “in-vehicle device screen display”, and the “synthetic data” is an “in-vehicle device screen”.
On a line 415, it is described that in a case where the selected “part” is “all input”, the “limitation region” is a “full screen region and all keys”, the “limitation display method” is “none”, and the “synthetic data” is “none”.
For example, in a case where the vehicle state determination unit 206 extracts the “display part A”, and the display of the “display part A” is limited, when the line 405 is read out, the “limitation region” is the “rectangular region (x1, y1)-(x2, y2)”, the “limitation method” is the “superposition”, and the “synthetic data” used for the superposition is the “image data A”. The “rectangular region (x1, y1)-(x2, y2)” represents a rectangular region in which coordinates (x1, y1) and coordinates (x2, y2) of display of the mobile phone are apexes of opposite angles. In this case, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the “image data A” on the “rectangular region (x1, y1)-(x2, y2)” of the display of the mobile phone 103 for displaying, and to limit the display of the mobile phone 103 to the display device 111 of the in-vehicle device 101.
In a case where the display of the “display part B” is limited, when the line 406 and the line 407 are read out, the “limitation regions” are the “rectangular region (x3, y3)-(x4, y4)” and the “rectangular region (x5, y5)-(x6, y6)”. The “limitation display method” of the “rectangular region (x3, y3)-(x4, y4)” is the “superposition”, and the “synthetic data” is the “image data B”, while the “limitation display method” of the “rectangular region (x5, y5)-(x6, y6)” is the “superposition”, and the “synthetic data” is the “gray”.
In a case where the display of the “display part C” is limited, when the line 408 is read out, the “limitation region” is the “rectangular region (x7, y7)-(x8, y8)”, the “limitation display method” is the “superposition”, and the “synthetic data” is the “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 for displaying, and the display of the mobile phone 103 to the display device 111 of the in-vehicle device 101 is limited.
In a case where the input of the “input part a” is limited, when the line 409 is read out, the “limitation region” is the “rectangular region (x5, y5)-(x6, y6)”. In this case, the vehicle state determination unit 206 instructs the input limitation unit 204 not to output the input to the “rectangular region (x5, y5)-(x6, y6)” to the in-vehicle device vehicle-interior communication control unit 209.
In a case where the input of the “input part b” is limited, when the line 410 and the line 411 are read out, the “limitation regions” are the “rectangular region (x7, y7)-(x8, y8)” and the “selection key”. In this case, the vehicle state determination unit 206 instructs the input limitation unit 204 not to output the input of the “rectangular region (x7, y7)-(x8, y8)” and the “selection key” to the in-vehicle device vehicle-interior communication control unit 209.
In a case where the display of the “full screen A” is limited, when the line 412 is read out, the “limitation region” is the “full screen region”, the “limitation display methods” are the “reduced size 1⁄5 display”, and the “in-vehicle device screen for reduced size 1⁄5 and mobile phone screen for reduced size 1⁄5”. The “reduced size 1⁄5 display” means that the whole display of the mobile phone 103 is reduced in size to 1⁄5, and superimposed on the screen of the in-vehicle device for displaying. In this case, the vehicle state determination unit 206 instructs the in-vehicle device input/output switching unit 202 to process the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for reduced size 1⁄5, to reduce the display data of the mobile phone 103 received from the in-vehicle device vehicle-interior communication control unit 209 to 1⁄5, and to pass the same to the output limitation unit 205. Furthermore, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the display data of the mobile phone 103, which is reduced in size to 1⁄5 and received from the in-vehicle device input/output switching unit 202 on the display data of the in-vehicle device application unit 201, which is processed to the in-vehicle device screen for reduced size 1⁄5, to pass the same to the in-vehicle device display control unit 208 for displaying.
In a case where the display of the “full screen B” is limited, when the line 413 is read out, the “limitation region” is the “full screen region”, the “limitation display method” is the “icon display”, and the “synthetic data” is the “in-vehicle device screen for icon and icon data”. The “icon display” means that the display of the mobile phone 103 is not performed, and the “icon data” of the application run by the mobile phone 103 is superimposed on the screen of the in-vehicle device. In this case, the vehicle state determination unit 206 passes the icon data to the in-vehicle device input/output switching unit 202, and instructs the in-vehicle device input/output switching unit 202 to process the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for icon, and to pass the same together with the icon data to the output limitation unit 205. Furthermore, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the icon data on the display data of the in-vehicle device application unit 201, which is processed to the in-vehicle device screen for icon received from the in-vehicle device input/output switching unit 202, and to pass the same to the in-vehicle device display control unit 208 for displaying.
In a case where the display of the “full screen C” is limited, when the line 414 is read out, the “limitation region” is the “full screen region”, the “limitation display method” is the “in-vehicle device screen display”, and the “synthetic data” is the “in-vehicle device screen”. The “in-vehicle device screen display” means that the display of the mobile phone 103 is not performed, and the screen of the application run by the mobile phone 103 is displayed. 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 limitation unit 205. Furthermore, the vehicle state determination unit 206 instructs the output limitation unit 205 to pass the display data of the in-vehicle device application unit 201 received from the in-vehicle device input/output switching unit 202 to the in-vehicle device display control unit 208 for displaying.
In a case where the “all input” is limited, when the line 415 is read out, the “limitation region” is the “full screen region and all keys”. In this case, the vehicle state determination unit 206 instructs the input limitation unit 204 not to output all input to the in-vehicle device vehicle-interior communication control unit 209.

Reference numeral 507 denotes an example of a screen of the application in a case where the parking brake is OFF, and the vehicle speed exceeds 50 km/h.
Reference numeral 508 denotes a full screen region of the display device 111 included in the in-vehicle device 101. Reference numeral 509 denotes a selection key of the input device 110 included in the in-vehicle device 101. Reference numeral 510 denotes a return key of the input device 110 included 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 region (x5, y5)-(x6, y6) of the display device 111 included in the in-vehicle device 101. Reference numeral 514 denotes a rectangular region (x7, y7)-(x8, y8) of the display device 111 included in the in-vehicle device 101. Reference numeral 515 denotes a display region of a mobile phone screen reduced in size to 1⁄5 of the display device 111 included in the in-vehicle device 101. Reference numeral 516 denotes a display region of a mobile phone application icon of the display device 111 included in the in-vehicle device 101.
In the case where the parking brake is ON, and the vehicle speed is 0 km/h, only the conditions of the line 305 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts “none” as the “display limitation part” and “none” as the “operation limitation part” from the table of FIG. 4. Since the “display limitation part” is “none”, and hence the vehicle state determination unit 206 instructs the in-vehicle device input/output switching unit 202 to pass the input received from the in-vehicle device input control unit 207 to the input limitation unit 204 without any change, and to pass the display data of the mobile phone 103 received from the in-vehicle device vehicle-interior communication control unit 209 to the output limitation unit 205 without any change. Furthermore, the vehicle state determination unit 206 instructs the input limitation unit 204 to pass the input received from the in-vehicle device input/output switching unit 202 to the mobile phone 103 through the in-vehicle device vehicle-interior communication control unit 209 without any change, and instructs the output limitation unit 205 to pass the display data of the mobile phone 103 received from the in-vehicle device input/output switching unit 202 to the in-vehicle device display control unit 208 without any change, and to display the same on the display device 111 of the in-vehicle device 101. Therefore, a screen of the example 501 of the screen in the case where the parking brake is ON, and the vehicle speed is 0 km/h is the same display as the screen of the mobile phone application unit 210 of the mobile phone 103, and operation to any region of the screen is transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed is 0 km/h, only the conditions of the line 306 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “display part A” as the “display limitation part” and “none” as the “operation limitation part” from the table of FIG. 4. Then, the line 405, the “part” of which is the “display part A”, is extracted from the table of FIG. 5, and the “limitation region” is the “rectangular region (x1, y1)-(x2, y2)”, the “limitation method” is the “superposition”, the “synthetic data” used for the superposition is the “image data A”. The “rectangular region (x1, y1)-(x2, y2)” represents a rectangular region in which coordinates (x1, y1) and coordinates (x2, y2) in the screen of the mobile phone 103 are apexes of opposite angles. In this case, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the “image data A” on the “rectangular region (x1, y1)-(x2, y2)” of the screen of the mobile phone 103 for displaying, and to limit the display of the mobile phone 103 to the display device 111 of the in-vehicle device 101. Therefore, in the example 502 of the screen in the case where the parking brake is OFF, and the vehicle speed is 0 km/h, the image data A of the display of the mobile phone application unit 210 of the mobile phone 103 is displayed on the rectangular region (x1, y1)-(x2, y2) 511. However, operation to any region of the screen is transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed exceeds 0 km/h and is 20 km/h or less, only the conditions of the line 306 and the line 307 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “display part A” and the “display part B” as the “display limitation part”, and “none” and the “input part a” as the “operation limitation part” from the table of FIG. 4. Then, the line 405, the line 406, the line 407 and the line 409, the “parts” of which are the “display part A”, the “display part B”, and the “input part a”, are extracted from the table of FIG. 5. The vehicle state determination unit 206 instructs the output limitation unit 205 to limit the display of the rectangular region (x1, y1)-(x2, y2) 511, the rectangular region (x3, y3)-(x4, y4) 512, and the rectangular region (x5, y5)-(x6, y6) 513. Furthermore, the vehicle state determination unit 206 instructs the input limitation unit 204 to limit the input of the rectangular region (x5, y5)-(x6, y6) 513. Therefore, in the example 503 of the screen in the case where the parking brake is OFF, and the vehicle speed exceeds 0 km/h and is 20 km/h or less, of the display of the mobile phone application unit 210 of the mobile phone 103, the image data A is displayed on the rectangular region (x1, y1)-(x2, y2) 511, the image data B is displayed on the rectangular region (x3, y3)-(x4, y4) 512, the gray rectangle is displayed on the rectangular region (x5, y5)-(x6, y6) 513, and the input to the rectangular region (x5, y5)-(x6, y6) 513 is not transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed exceeds 20 km/h and is 30 km/h or less, the conditions of the line 306, the line 307 and the line 308 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “display part A”, the “display part B”, and the “display part C” as the “display limitation part”, and “none” and the “input part a” and the “input part b” as the “operation limitation part” from the table of FIG. 4. Furthermore, the line 405, the line 406, the line 407, the line 408, the line 409, the line 410 and the line 411, the “parts” of which are the “display part A”, the “display part B”, the “display part C”, the “input part a” and the “input part b”, are extracted from the table of FIG. 5. Then, the vehicle state determination unit 206 instructs the output limitation unit 205 to limit the display of the rectangular region (x1, y1)-(x2, y2) 511, the rectangular region (x3, y3)-(x4, y4) 512, the rectangular region (x5, y5)-(x6, y6) 513, and the rectangular region (x7, y7)-(x8, y8) 514. Furthermore, the vehicle state determination unit 206 instructs the input limitation unit 204 to limit the input of the rectangular region (x5, y5)-(x6, y6) 513, the rectangular region (x7, y7)-(x8, y8) 514, and the selection key. Therefore, in the example 504 of the screen in the case where the parking brake is OFF, and the vehicle speed exceeds 20 km/h and is 30 km/h or less, of the display of the mobile phone application unit 210 of the mobile phone 103, the image data A is displayed on the rectangular region (x1, y1)-(x2, y2) 511, the image data B is displayed on the rectangular region (x3, y3)-(x4, y4) 512, the gray rectangle is displayed on the rectangular region (x5, y5)-(x6, y6) 513, the gray rectangle is displayed on the rectangular region (x7, y7)-(x8, y8) 514, and the input to the rectangular region (x5, y5)-(x6, y6) 513, the rectangular region (x7, y7)-(x8, y8) 514, and the selection key is not transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed exceeds 30 km/h and is 40 km/h or less, only the conditions of the line 309 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “full screen A” as the “display limitation part”, and the “all input” as the “operation limitation part” from the table of FIG. 4. Furthermore, the line 412 and the line 415, the “parts” of which are the “full screen A” and the “all input” are extracted from the table of FIG. 5. Then, the vehicle state determination unit 206 instructs the in-vehicle device input/output switching unit 202 to process the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for reduced size 1⁄5, to reduce the display data of the mobile phone 103 received from the in-vehicle device vehicle-interior communication control unit 209 to 1⁄5, and to pass the same to the output limitation unit 205. Furthermore, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the display data of the mobile phone 103, which is reduced in size to 1⁄5 and received from the in-vehicle device input/output switching unit 202, on the display data of the in-vehicle device application unit 201, which is processed to the in-vehicle device screen for reduced size 1⁄5, and to pass the same to the in-vehicle device display control unit 208 for displaying, and instructs the input limitation unit 204 not to output all of the input to the in-vehicle device vehicle-interior communication control unit 209. Therefore, in the example 505 of the screen in the case where the parking brake is OFF, and the vehicle speed exceeds 30 km/h and is 40 km/h or less, the in-vehicle device screen for reduced size 1⁄5 is displayed on the full screen region 508 of the display device 111 of the in-vehicle device 101, and the display data of the mobile phone 103, which is reduced in size to 1⁄5, is displayed on the display region 515 of the mobile phone screen for reduced size 1⁄5, and all of the input is not transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed exceeds 40 km/h and is 50 km/h or less, only the conditions of the line 310 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “full screen B” as the “display limitation part”, and the “all input” as the “operation limitation part” from the table of FIG. 4. Furthermore, the line 413 and the line 415, the “parts” of which are the “full screen B” and the “all input” are extracted from the table of FIG. 5. Then, the vehicle state determination unit 206 passes the icon data to the in-vehicle device input/output switching unit 202, and instructs the in-vehicle device input/output switching unit 202 to process the display data of the in-vehicle device application unit 201 to the in-vehicle device screen for icon, and to pass the same together with the icon data to the output limitation unit 205. Furthermore, the vehicle state determination unit 206 instructs the output limitation unit 205 to superimpose the icon data on the display data of the in-vehicle device application unit 201, which is processed to the in-vehicle device screen for icon received from the in-vehicle device input/output switching unit 202, and to pass the same to the in-vehicle device display control unit 208 for displaying. Moreover, the vehicle state determination unit 206 instructs the input limitation unit 204 not to output all of the input to the in-vehicle device vehicle-interior communication control unit 209. Therefore, in the example 506 of the screen in the case where the parking brake is OFF, and the vehicle speed exceeds 40 km/h and is 50 km/h or less, the in-vehicle device screen for icon is displayed on the full screen region 508 of the display device 111 of the in-vehicle device 101, and the icon is displayed on the display region 516 of the mobile phone application icon, and all of the input is not transmitted to the mobile phone 103.
In the case where the parking brake is OFF, and the vehicle speed exceeds 50 km/h, only the conditions of the line 311 of the table of FIG. 4 are met, and hence the vehicle state determination unit 206 extracts the “full screen C” as the “display limitation part”, and “all input” as the “operation limitation part” from the table of FIG. 4. Furthermore, the vehicle state determination unit 206 extracts the line 414 and the line 415, the “parts” of which are the “full screen C” and the “all input”, from the table of FIG. 5. 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 limitation unit 205, instructs the output limitation unit 205 to pass the display data of the in-vehicle device application unit 201, which is received from the in-vehicle device input/output switching unit 202, to the in-vehicle device display control unit 208 for displaying, and instructs the input limitation unit 204 not to output all of the input to the in-vehicle device vehicle-interior communication control unit 209. Therefore, in the example 507 of the screen in the case where the parking brake is OFF, and the vehicle speed exceeds 50 km/h, the in-vehicle device screen is displayed on the full screen region 508 of the display device 111 of the in-vehicle device 101, and all of the input is not transmitted to the mobile phone 103.
FIG. 7 is a figure showing an example of a table for managing limitation conditions of display and operation according to a predetermined vehicle state. A configuration thereof is similar to that of the table of the limitation condition information of FIG. 4. Configurations denoted by the same reference numerals as those shown in FIG. 4, which are already described, and portions having the same functions are not repeatedly described.
On a line 601, it is described that in a case where the “parking brake state” is “ON”, and the “vehicle speed” is “vehicle speed=0 km/h”, the “display limitation part” is “none”, and the “operation limitation part” is “none”. On a line 602, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “vehicle speed=0 km/h”, the “display limitation part” is a “display part B”, and the “operation limitation part” is “all input”. On a line 603, it is described that in a case where the “parking brake state” is “OFF”, and the “vehicle speed” is “0 km/h<vehicle speed”, the “display limitation part” is a “display part C”, and the “operation limitation part” is “all input”.
Thus, it is possible to correspond to various applications for general purposes without being influenced by the display contents of the applications of the mobile phone by setting an item entered in the “display limitation part” as “none” or the limitation parts to the whole display of the mobile phone 103, and setting an item entered in the “operation limitation part” as “none” or the parts to all input.
FIG. 8 is a figure showing a configuration of a table for managing limitation parts of predetermined display and operation, and a limitation method. The configuration thereof is similar to that of the table of the limitation method information of FIG. 5. Configurations denoted by the same reference numerals as those shown in FIG. 5, which are already described, and portions having the same functions are not repeatedly described.
On a line 701, it is described that in a case where the “part” is the “full screen B”, the “limitation region” is the “full screen region”, the “limitation display method” is the “icon display”, and the “synthetic data” is the “in-vehicle device screen for icon and icon data”. On a line 702, it is described that in a case where the selected “part” is “full screen C”, the “limitation region” is the “full screen region”, the “limitation display method” is the “in-vehicle device screen display”, and the “synthetic data” is the “in-vehicle device screen”. On a line 703, it is described that in a case where the selected “part” is the “all input”, the “limitation region” is the “full screen region and all keys”, the “limitation display method” is “none”, and the “synthetic data” is “none”.
As in the table of FIG. 8, it is determined that the “full screen B” and the “full screen C” used in FIG. 7 are limitation parts to the whole display of the mobile phone 103, and it is determined that the “all input” is a method of not transmitting all of the input to the mobile phone 103, thereby enabling input and output to be limited to various applications for general purposes without being influenced by the display contents of the applications of the mobile phone.
FIG. 9 shows an example of a configuration of a table for managing input/output limitation information delivered from the server.
An “in-vehicle device model ID” 801 is an ID inherent in the model of the in-vehicle device. A “mobile phone app ID” 802 is an ID inherent in the individual application run by the mobile phone 103. An “input/output limitation information” 803 is input/output limitation information delivered by the server 105, and has the same configuration as the input/output limitation information 216.
On a line 804, it is described that “input/output limitation information” delivered in a case where the “in-vehicle device model ID” is an “in-vehicle device A”, and the “mobile phone app ID” is a “mobile phone app a” is “input/output limitation information Aa”. On a line 805, it is described that “input/output limitation information” delivered in a case where the “in-vehicle device model ID” is an “in-vehicle device A”, and the “mobile phone app ID” is a “mobile phone app b” is “input/output limitation information Ab”. On a line 806, it is described that “input/output limitation information” delivered in a case where the “in-vehicle device model ID” is an “in-vehicle device B”, and the “mobile phone app ID” is the “mobile phone app a” is “input/output limitation information Ba”. On a line 807, it is described that “input/output limitation information” delivered in a case where the “in-vehicle device model ID” is the “in-vehicle device B”, and the “mobile phone app ID” is the “mobile phone app b” is “input/output limitation information Bb”.

A case where an in-vehicle device model ID list of the compatible in-vehicle device information 219 of the input/output limitation information 216 of the in-vehicle device application unit 201 includes the in-vehicle device model ID of the limitation information inquiry (in-vehicle device model ID) 907, and input/output limitation information suitable for the in-vehicle device 904 exists will be considered.
First, input/output limitation information transmission 908 is performed to the in-vehicle device 904, and the input/output limitation information 216 is passed to the in-vehicle device 904.
The in-vehicle device 904 performs input/output limitation information setting 909. That is, the input/output limitation information 216 received by the in-vehicle device vehicle-interior communication control unit 209 is passed to the input/output limitation information storage unit 203, and is written in the input/output limitation information region 221.
In a case where the in-vehicle device model ID list of the compatible in-vehicle device information 219 of the input/output limitation information 216 of the in-vehicle device application unit 201 does not include the in-vehicle device model ID of the limitation information inquiry (in-vehicle device model ID) 907, and the input/output limitation information suitable for the in-vehicle device 904 does not exist, the mobile phone 903 makes a limitation information inquiry (an in-vehicle device model ID and a mobile phone app ID) 910 to the server 901, and the in-vehicle device model ID and the mobile phone app ID are passed to the server 901.
In a case where the combination of the in-vehicle device model ID and the mobile phone app ID received by the server 901 exists in the input/output limitation information management table, and input/output limitation information suitable for the combination of the applications run by the in-vehicle device 904 and the mobile phone 903 exists in the server 901, the delivery unit 222 extracts the input/output limitation information from the input/output limitation information management table 223, performs input/output limitation information transmission 911 to the mobile phone 903, and passes the input/output limitation information 216 to the mobile phone 903.
The mobile phone 903 performs input/output limitation information transmission 912, and passes the input/output limitation information 216 received from the server 901 to the in-vehicle device 904.
The in-vehicle device 904 performs input/output limitation information setting 913, and writes the input/output limitation information 216 received from the server 901 in the input/output limitation information region 221.
In a case where the combination of the in-vehicle device model ID and the mobile phone app ID received by the server 901 does not exist in the input/output limitation information management table, and input/output limitation information suitable for the combination of the applications run by the in-vehicle device 904 and the mobile phone 903 does not exist in the server 901, the server 901 sends a notification of no input/output limitation information 914 to the mobile phone 903.
The mobile phone 903 sends a notification of no input/output limitation information 915 to the in-vehicle device 904. The in-vehicle device 904 performs predetermined input/output limitation information setting 916. The input/output limitation information storage unit 203, which receives the notification of no input/output limitation information through the in-vehicle device vehicle-interior communication control unit 209, writes the contents of the predetermined input/output limitation information 220 in the input/output limitation information region 221.
During linkage operation, input 917 from the user 902 to the in-vehicle device 904, input 918 from the in-vehicle device 904 to the mobile phone 903, output 919 from the mobile phone 903 to the in-vehicle device 904, output 920 from the in-vehicle device 904 to the user 902 are repeated. At this time, the vehicle state determination unit 206 acquires a vehicle state from the vehicle state sensor 102, performs control of the in-vehicle device input/output switching unit 202, the input limitation unit 204, and the output limitation unit 205 in accordance with the input/output limitation information 216 or the predetermined input/output limitation information 220, which is written in a input/output limitation information storage region, controls whether or not the input 917 received by the in-vehicle device input control unit 207 is passes to the mobile phone 903 as the input 918 through the in-vehicle device vehicle-interior communication control unit 209, processes display data of the output 919 received by the in-vehicle device vehicle-interior communication control unit 209, displays the same on the display device 111 through the in-vehicle device display control unit 208, and passes the same as the output 920 to the user 902.
Finally, disconnection 921 is notified by the in-vehicle device 904 to the mobile phone 903, and remote control of the mobile phone 903 by the in-vehicle device 904 is terminated.
FIG. 11 is an example of a flow of a vehicle state determination unit.
First, the vehicle state determination unit 206 acquires a vehicle state with the vehicle state sensor 102 in Step 1001. In Step 1002, the input/output limitation information storage unit 203 reads in input/output limitation information stored in the input/output limitation information region 221. In Step 1003, the vehicle state determination unit 206 acquires a “display limitation part” and a “operation limitation part” applied to the vehicle state, which are acquired from the table (FIG. 4 or FIG. 7) for managing the limitation conditions of display and operation in Step 1001.
In Step 1004, a “limitation region”, a “limitation display method” and “synthetic data” corresponding to the “display limitation part” and the “operation limitation part” acquired in Step 1003 are acquired from the table (FIG. 5 or FIG. 8) for managing the limitation region of display and operation and the limitation display method.
In Step 1005, in accordance with the “limitation region”, the “limitation display method” and the “synthetic data” acquired in Step 1004, the in-vehicle device input/output switching unit 202, the input limitation unit 204, and the output limitation unit 205 are controlled to limit display and operation.
According to the present practical example, in a case where display or operation is performed with the in-vehicle device 101 even when the parking brake is OFF, the application on the mobile phone 103 previously holds the input/output limitation information 216 for limitation according to the vehicle state. Before start of the display of the application with the in-vehicle device 101, the in-vehicle device 101 acquires the input/output limitation information 216 from the application, and changes transmission ranges of display and operation according to the vehicle state.
According to the present practical example, in order to address a case where the application on the mobile phone 103 previously does not have the input/output limitation information, the input/output limitation information is held in the server 105 of a center. Before the start of the display of the application with the in-vehicle device 101, the in-vehicle device 101 acquires the input/output limitation information from the center, and changes the transmission ranges of display and operation according to the vehicle state.
According to an aspect of the present practical example, in a case where an input/output device of the in-vehicle device is used, and the application of the mobile phone is utilized, in various combinations of the in-vehicle device and the mobile phone, active and inactive of display and operation of the general-purpose application of the mobile phone by the in-vehicle device 101 can be controlled according to the vehicle state. Furthermore, a method of controlling active and inactive of operation and the screen of the in-vehicle device 101 can be changed for each application by changing the input/output limitation information of the center, and various applications can be safely utilized.
According to an aspect of the present practical example, when the display or the operation of the application with the in-vehicle device 101 is started, the input/output limitation information is incorporated in the in-vehicle device 101, and hence the user can easily apply limitation information easily enabling safe display or operation by preparing the mobile phone 103 serving as a control target device and the in-vehicle device 101 serving as a control instruction device, even in a case of utilizing a new mobile phone 103 or a new application with the in-vehicle device 101.
The aforementioned embodiment and practical example of the present invention are exemplification for explanation of the present invention, and the scope of the present invention is not limited to these embodiment and practical example. A person in skilled in the art can practice the present invention in various aspects without departing the spirit and scope of the present invention.
For example, while the region where operation is limited is displayed in gray in the present practical example, the present invention is not limited to this. The region where operation is limited may be displayed in color other than gray. Alternatively, the region may be configured that the user can set the color to be displayed.
