Description

  The present invention relates to an in-vehicle system having an in-vehicle device having a display unit mounted on a vehicle and a mobile terminal device connected to the in-vehicle device by wireless communication.

  With the spread of car navigation systems using GPS (Global Positioning System), in-vehicle devices having a navigation function are often mounted on vehicles. In addition, in order to respond to user needs for multifunctional in-vehicle devices, multifunctional in-vehicle devices have become prominent.

  For example, in-vehicle devices often include many functions such as a television reception function, a CD (Compact Disc) playback function, and a DVD (Digital Versatile Disk) playback function in addition to the navigation function. However, the increase in the number of functions of the in-vehicle device causes an increase in the price of the in-vehicle device, which is not preferable for the user.

  On the other hand, portable terminal devices such as mobile phones have been popularized at low prices but with navigation functions and music playback functions. In addition, since mobile terminal devices equipped with a short-range wireless communication function such as Bluetooth (registered trademark) have also become widespread, the mobile terminal device and the vehicle-mounted device are linked with such a short-range wireless communication function, and the mobile terminal device side Efforts are also being made to use functions on the in-vehicle device side. This makes it possible to reduce the price of the in-vehicle device.

  For example, Patent Literature 1 discloses a technique for transmitting a display screen displayed on a screen of a mobile terminal device to an in-vehicle device and displaying a display screen generated by the mobile terminal device on a display of the in-vehicle device. Yes.

  However, since the above-described conventional technology can control the in-vehicle device even while the vehicle is traveling, there is a problem in that it hinders driving and inhibits safe driving.

  Specifically, the conventional technology such as Patent Document 1 assumes an inexpensive audio display that does not have a car navigation system or the like, and therefore does not have a high-performance function that prohibits operation while traveling. Is common. Therefore, when the vehicle-mounted device and the mobile terminal device are connected to each other by wireless communication, that is, in cooperation with each other using the technology as described in Patent Document 1, and the car navigation system is used in the vehicle-mounted device, the driver is driving the vehicle. However, the vehicle-mounted device can be operated.

  In addition, when a vehicle-mounted device and a mobile terminal device are linked using a high-performance vehicle-mounted device having a car navigation system or the like, the vehicle-mounted device side may perform a control for rejecting (not accepting) an operation during traveling. it can. On the other hand, since the mobile terminal side that communicates with the outside accepts the operation even while traveling, information that executes the accepted operation during traveling is transmitted to the in-vehicle device. Therefore, when viewed in the entire in-vehicle system having the in-vehicle device and the mobile terminal device, the driver can operate the in-vehicle device even when the vehicle is traveling.

  Therefore, the present invention has been made to solve the above-described problems of the prior art, and when the vehicle is traveling, an in-vehicle system that can suppress unnecessary operations and promote safe driving. The purpose is to provide.

  In order to solve the above-described problems and achieve the object, the present invention is an in-vehicle system having an in-vehicle device having a display unit mounted on a vehicle and a mobile terminal device connected to the in-vehicle device by wireless communication. The vehicle-mounted device acquires travel information of the vehicle and transmits the travel information to the mobile terminal device connected by the wireless communication and the mobile terminal device cooperatively connected by the wireless communication. Operation information transmitting means for transmitting operation information for specifying the operated content to the portable terminal device when the information displayed on the display unit is operated by a user. When the mobile terminal device receives the operation information from the in-vehicle device, the mobile terminal device determines whether to restrict the operation specified by the operation information based on the travel information of the vehicle. If it is determined that the operation is not restricted by the operation determining means, it is determined that the operation result obtained by executing the operation is responded to the in-vehicle device and the operation is restricted by the operation determining means. In such a case, an operation control means for rejecting the operation is provided.

  According to the present invention, when the vehicle is traveling, unnecessary operations can be suppressed and safe driving can be promoted.

  Embodiments of an in-vehicle system according to the present invention will be described below in detail with reference to the accompanying drawings. In the following, the outline of the in-vehicle system according to the present embodiment, the configuration of the in-vehicle system, and the flow of processing will be described in order, and finally various modifications to the present embodiment will be described.

  First, main terms used in this embodiment will be described. The “in-vehicle system” used in the present embodiment is a system in which an in-vehicle device called DA (display Audio) mounted in an automobile and a mobile terminal that receives an application or data from a server device cooperate with each other by a short-range wireless communication function. That is.

  Here, DA refers to an in-vehicle device that is mounted with only basic functions such as a display function, an audio playback function, and a communication function with a mobile terminal device, and becomes multi-functional by cooperating with the mobile terminal device. Therefore, the in-vehicle device used in the present embodiment is a device that is inexpensive compared to a highly accurate in-vehicle device mounted on a vehicle in recent years, and can be expected to spread.

  The mobile terminal has a short-range wireless communication function such as Bluetooth (registered trademark) and infrared communication, and various functions such as a mail function, an Internet connection function (Web connection function), a music player function, and a moving image playback function. For example, a personal computer, a PDA, or a mobile communication terminal such as a mobile phone or PHS.

[Outline of in-vehicle system]
Next, the outline of the in-vehicle system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram for explaining the outline of the in-vehicle system according to the first embodiment.

  As shown in FIG. 1, an in-vehicle system links an in-vehicle device called DA installed in an automobile with a mobile terminal that receives applications and data from a server device, and performs unnecessary operations when the vehicle is running. It can be deterred and promote safe driving. It should be noted that the in-vehicle device and the mobile terminal device referred to here are connected to each other by wireless communication, that is, the cooperation means that the information updated in the mobile terminal is reflected in the in-vehicle device, and the information updated in the in-vehicle device is When the operation by the user is received by the in-vehicle device that displays the image of the application being executed on the mobile terminal, the operation content is executed on the mobile terminal side. Outputs the operation result.

  Specifically, the in-vehicle device acquires vehicle travel information and transmits it to a mobile terminal connected by wireless communication (see (1) and (2) in FIG. 1). For example, when a pairing process is performed between the in-vehicle device and the mobile terminal and wireless communication is established, the in-vehicle device periodically transmits information such as speed, acceleration, and presence / absence of braking from various sensors of the vehicle, that is, travel information. Acquired and transmitted to a mobile terminal connected by wireless communication.

  The in-vehicle device is information acquired from a mobile terminal linked and connected by wireless communication, and when the information displayed on a display unit such as a display is operated by a user, the operated content is specified. The operation information to be transmitted is transmitted to the portable terminal (see (3) and (4) in FIG. 1). As a specific example, it is assumed that the in-vehicle device acquires navigation information from a mobile terminal and displays it, and the user selects a destination change button. In this case, an operation command indicating the selected coordinates or the selected destination change button is transmitted to the mobile terminal.

  Subsequently, when receiving the operation information from the in-vehicle device, the mobile terminal determines whether to restrict the operation specified by the operation information based on the travel information of the vehicle ((5) in FIG. 1). If it is determined that the operation is not restricted, the operation result obtained by executing the operation is returned to the in-vehicle device, and if it is determined that the operation is restricted, the operation is rejected (see FIG. 1 (6)). Here, “reject” means that the operation is not executed or that the execution result is not responded to the in-vehicle device even if the operation is executed.

  More specifically, the mobile terminal receives coordinates indicating a destination change button or an operation command indicating the destination change button from the in-vehicle device. Then, if the recently received travel information of the vehicle is “running” or can be determined as “running” from the vehicle travel information, the mobile terminal determines that the destination change is to be restricted and rejects the operation. A response to that effect is transmitted to the in-vehicle device. In addition, when the recently received vehicle travel information is “stopped” or can be determined as “stopped” from the vehicle travel information, the mobile terminal determines that the destination change is not regulated, and As a response, a screen for inputting a new destination is transmitted to the in-vehicle device.

  As described above, in the in-vehicle system according to the first embodiment, the vehicle is running even when the in-vehicle device and the mobile terminal are connected in a cooperative manner by wireless communication or using an inexpensive DA that is not high-performance. In this case, the operation can be suppressed on the portable terminal side. As a result, unnecessary operations not required for driving can be suppressed and safe driving can be promoted. The determination “running” is made on the condition that vehicle speed and acceleration are occurring. The determination of “stopped” is made on the condition that no vehicle speed or acceleration has occurred or that the brake is not operating.

Moreover, it is good also as performing communication between the vehicle equipment 10 / the portable terminal 40 by wired communication.

  The display operation unit 12 is connected to the control unit 15 and displays and outputs an image output from the control unit 15. Specifically, the display operation unit 12 includes an input / output device such as a touch panel display, and displays a display screen that is received from the mobile terminal 40 and converted into a format that can be output by the control unit 15. Get touch information for the screen. Here, the touch information is information including coordinates on the touched display, a time interval from the touch to the next touch, and the like. The display operation unit 12 notifies the control unit 15 of the acquired touch information.

  The control unit 15 has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and necessary data, and a radio establishment unit 16, a travel information transmission unit 17, The display control unit 18 and the operation information transmission unit 19 have various processes.

  The wireless establishment unit 16 establishes wireless communication with respect to the mobile terminal 40 located at a predetermined distance capable of wireless communication with the in-vehicle device 10. Specifically, when the power of the device is turned on, the wireless establishing unit 16 activates the short-range communication unit 11 and searches for a terminal in an area where wireless communication is possible. And when the portable terminal 40 penetrate | invades in the area | region which can be wirelessly communicated, the radio | wireless establishment part 16 detects the portable terminal 40 which entered, and the pairing process using the short-range communication part 11 with respect to the detected portable terminal 40 To establish wireless communication with the mobile terminal 40.

  The wireless establishment unit 16 can also establish wireless communication with the mobile terminal according to a user operation. For example, a cooperation start button with the portable terminal is displayed on the display operation unit 12 to be described later, and when this button is pressed by the user, the wireless establishment unit 16 activates the short-range communication unit 11 to perform wireless communication. Search for a terminal in a possible area. And when the wireless establishment part 16 detects the portable terminal 40, it will perform the pairing process using the short-range communication part 11 with respect to the detected portable terminal 40, and establish wireless communication between the portable terminals 40 To do.

  The travel information transmission unit 17 acquires the travel information of the vehicle and transmits it to the mobile terminal 40 connected by wireless communication. To give a specific example, the travel information transmitting unit 17 may receive a signal from various sensors of the vehicle control system unit 20 at predetermined intervals, for example, once every 5 minutes or when there is a change from the previously acquired travel state. As the traveling state of the vehicle, “speed, acceleration, braking state, steering position, current location, parking brake state, shift lever position” and the like are acquired and transmitted to the portable terminal 40 via the short-range communication unit 11.

  The display control unit 18 converts various data into a format that can be output by the in-vehicle device 10 when data is received from the mobile terminal 40 after wireless communication is established with the information mobile terminal 40. And output to the display operation unit 12 and / or the speaker 30. Specifically, the display control unit 18 converts an image received via the short-range communication unit 11 after wireless communication is established with the information portable terminal 40 into a format that can be displayed by the own device. Or converted into an image suitable for the display (or touch panel) of the display operation unit 12 and displayed in a table. Also, the display control unit 18 converts the audio signal received via the short-range communication unit 11 after wireless communication is established with the information mobile terminal 40 into a format that can be output by the own device. Output from the speaker 30.

  For example, the display control unit 18 may use the navigation information (guidance to the destination and destination) set in the mobile terminal 40 via the short-range communication unit 11 after wireless communication is established with the information mobile terminal 40. When an image or sound up to the route is acquired, the acquired navigation image is an image that matches the width (W pixels) × height (H pixels) of the display (or touch panel) of the display operation unit 12. The converted navigation sound is displayed on the display operation unit 12, and the acquired navigation sound is converted into a format that can be output by the own device and output from the speaker 30.

  Thereafter, the display control unit 18 converts the information (navigation image and navigation voice) transmitted and acquired every time the travel route is guided on the mobile terminal 40 side into a format that can be output by the in-vehicle device 10 and displays the information. Output to the operation unit 12 and / or the speaker 30.

  The operation information transmission unit 19 is information acquired from the portable terminal 40 linked and connected by wireless communication, and when the information displayed on the display operation unit 12 is operated by the user, the operation information is specified. The operation information to be transmitted is transmitted to the portable terminal 40. As a specific example, the operation information transmission unit 19 receives touch information from the display operation unit 12 and performs processing for notifying the received touch information to the mobile terminal 40 via the short-range communication unit 11.

  Further, the mobile terminal 40 converts the notified touch information into an input operation on the display screen, operates the application based on the input operation, and performs processing such as display screen update. Then, the operation result of the operation transmitted to the portable terminal 40 by the operation information transmitting unit 19 is output from the portable terminal 40 and acquired via the short-range communication unit 11, and then is displayed on the in-vehicle device 10 by the display control unit 18. Is output to the display operation unit 12 and / or the speaker 30. The information notified to the mobile terminal 40 by the operation information transmitting unit 19 is an operation command specified from coordinates indicating an operated position or an operated position.

  The operation information transmission unit 19 can also perform a scroll operation for moving the display content up, down, left, and right in order to display a portion that cannot be displayed on the display screen of the display operation unit 12. For example, as illustrated in FIG. 3A, the operation information transmission unit 19 divides the display of the display operation unit 12 into four. Then, as illustrated in FIG. 3A, the operation information transmission unit 19 determines the scroll direction and the amount of movement depending on how far the position touched by the user is located from the center of the four divisions. Thereafter, the operation information transmission unit 19 displays a screen on which the determined scroll direction and movement amount are moved.

  For example, when the distance from the center is less than “X”, the operation information transmission unit 19 determines that the scroll is one time, and the distance from the center is “X” or more and less than “Y”. In this case, it is determined as two scrolls, and when the distance from the center is “Y” or more, it is determined as three scrolls. Then, the operation information transmission unit 19 moves the determined scroll amount screen based on a reference such as one scroll = 10 cm, for example. 3A is a diagram illustrating an example of screen division of the display, and FIG. 3B is a diagram illustrating an example of the scroll movement amount.

(Configuration of mobile terminal 40)
Next, the configuration of the mobile terminal 40 in the in-vehicle system according to the first embodiment will be described. As illustrated in FIG. 2, the mobile terminal 40 includes a communication unit 41, a short-range communication unit 42, a speaker 43, a display operation unit 44, a storage unit 45, and a control unit 46.

  The communication unit 41 is a device that communicates with a server device or a GPS (Global Positioning System) communication device provided on a network such as the Internet via a base station of a communication carrier, for example. Specifically, when a navigation application is executed on the mobile terminal 40, the communication unit 41 communicates with the GPS or the like according to an instruction from the navigation application, and acquires the current position of the mobile terminal 40, etc. To do.

  The short-range communication unit 42 establishes a communication link with the vehicle-mounted device 10 using short-range wireless communication such as Bluetooth (registered trademark), as well as the short-range communication unit 11 of the vehicle-mounted device 10, and the established communication link Is used to perform communication processing between the mobile terminal 40 and the in-vehicle device 10.

  When the speaker 43 receives an audio signal from the control unit 46, which will be described later, the speaker 43 outputs the audio signal to the outside, and outputs the audio at the time of normal telephone connection to the outside. The display operation unit 44 includes an input / output device such as a touch panel display, and displays and outputs an image output from the control unit 46 and the like which will be described later.

  The storage unit 45 stores data and programs necessary for various processes performed by the control unit 46. For example, an application DB 45a that stores an application that is read and executed by the control unit 46, which will be described later, and traveling of the vehicle And a restriction information DB 45b that stores restriction information indicating whether or not the operation is restricted when the state is traveling.

  As described above, the application DB 45a is a database or memory that stores an application that is read and executed by the control unit 46, which will be described later. For example, a mobile terminal such as a navigation application, a music download application, or a moving image distribution application The application executable at 40 is stored.

  As described above, the restriction information DB 45b stores restriction information indicating whether or not the operation is restricted when the running state of the vehicle is running. Specifically, the restriction information DB 45b stores an application executed on the mobile terminal 40 and restriction information indicating whether or not the operation is restricted when the vehicle is running. For example, as shown in FIG. 4A, the restriction information DB 45b includes “navigation, yes”, “music player, no”, “TV viewing, no”, “mail transmission / reception, yes (automatic), as“ application, restriction information ”. "Reception: The transmission function is restricted, but reception is not regulated because it is performed automatically)".

  Further, for example, the restriction information DB 45b includes an object indicating a switch (SW) provided in advance in the in-vehicle device 10 and restriction information indicating whether or not the operation is restricted when the vehicle is running. It can also be stored in association. For example, as illustrated in FIG. 4B, the restriction information DB 45b includes “navigation SW, presence”, “music player SW, none”, “TV-related SW, none”, “air conditioner operation, “None” is stored. FIG. 4A is a diagram illustrating the regulation information when regulation is performed for each application stored in the regulation information DB, and FIG. 4B is a diagram when regulation is performed for each object stored in the regulation information DB. It is a figure which shows regulation information.

  The control unit 46 includes an internal memory for storing a control program such as an OS (Operating System), a program that defines various processing procedures, and necessary data, and performs processing such as voice calls and wireless communication. It has the establishment part 47, the operation determination part 48, and the operation control part 49, and performs various processes by these.

  The wireless establishment unit 47 is a processing unit that establishes wireless communication with the in-vehicle device 10, and specifically, when a pairing process or the like is received from the in-vehicle device 10 via the short-range communication unit 42. Then, a response to the processing is transmitted to the in-vehicle device 10 to establish wireless communication.

  The operation determination unit 48 is connected to the short-range communication unit 42, the speaker 43, and the display operation unit 44. When the operation information is received from the in-vehicle device 10, the operation determination unit 48 is specified by the operation information based on the vehicle travel information. It is determined whether or not the operation is restricted. Specifically, the operation determination unit 48 receives the operation information from the in-vehicle device 10 and can determine that the recently received vehicle travel information is “running” or “running” from the vehicle travel information. In this case, it is determined whether the restriction information corresponding to the operation information is “present” or “not present” with reference to the restriction information DB 45 b, and the result and the restriction information are output to the operation control unit 49. When the operation determination unit 48 receives the operation information from the in-vehicle device 10 and the recently received vehicle travel information is “stopped” or can be determined from the vehicle travel information “stopped”. Then, it is determined that the received operation information is permitted without referring to the restriction information DB 44b, and the result and restriction information are output to the operation control unit 49.

  For example, the operation determination unit 48 receives a “change target (destination change command)” as operation information from the in-vehicle device 10, and if the recently received vehicle travel information is “running”, the regulation is performed. It is determined with reference to the information DB 45b that the received “purpose change (destination change command)” is restricted. In addition, the operation determination unit 48 receives “tune selection (music player command)” as operation information from the in-vehicle device 10, and when the recently received vehicle travel information is “running”, the regulation information With reference to the DB 45b, it is determined that the received “tune selection (music player command)” is not restricted.

  Further, for example, when the operation determination unit 48 receives “air conditioner temperature change (temperature change command)” as operation information from the in-vehicle device 10 and the recently received vehicle travel information is “running”. Determines that the received “air conditioner temperature change (temperature change command)” is not restricted with reference to the restriction information DB 45b.

  Here, when the operation determination unit 48 receives the operation information from the in-vehicle device 10, the operation determination unit 48 determines whether the vehicle is traveling from the recently received traveling state and refers to the restriction information DB 45 b. As described above, for example, when the operation information is received from the in-vehicle device 10, the traveling state of the vehicle may be acquired from the in-vehicle device 10 to determine whether or not the vehicle is traveling. By doing so, the determination which considered the real time more can be performed.

  The operation control unit 49 is connected to the short-range communication unit 42, the speaker 43, and the display operation unit 44. When the operation determination unit 48 determines that the operation is not restricted, an operation result obtained by executing the operation In response to the vehicle-mounted device 10, if the operation determination unit 48 determines that the operation is restricted, the operation is rejected. Specifically, when the operation control unit 49 receives a determination result of restriction from the operation determination unit 48, the operation control unit 49 transmits a response indicating that the operation is rejected to the in-vehicle device 10 or rejects the operation. A voice or image message to that effect is output to the speaker 43 or the display operation unit 44.

  Further, when the operation control unit 49 receives a determination result indicating that no restriction is made from the operation determination unit 48, the operation control unit 49 performs an operation corresponding to the operation information received together with the determination result, and transmits the result to the in-vehicle device 10. Or the result is output to the speaker 42 or the display operation unit 43. For example, when a determination result indicating that no restriction is made is received from the operation determination unit 48, when the operation information received together with the determination result is “change destination (destination change command)”, “change destination (destination) As an operation corresponding to “Destination change command”, a “destination change screen” for inputting a new destination is transmitted to the in-vehicle device 10.

It transmits to the portable terminal 40 via the unit 11.

  When the user operation is detected by the display operation unit 12 (Yes at Step S103), the in-vehicle device 10 detects the detected operation information (for example, the operation command specified from the coordinates indicating the operation position, the detected operation position, etc.) ) Is transmitted to the portable terminal 40 (step S104).

  Thereafter, when the in-vehicle device 10 receives an image or sound of the operation result in which the transmitted operation information is executed or a response indicating that the operation is rejected from the portable terminal 40 (Yes in step S105), the on-vehicle device 10 displays the received image. The sound is output to the unit 12 or the received sound is output to the speaker 30 or the like (step S106).

  Then, the in-vehicle device 10 repeats the processes of Steps S103 to S107 described above while wireless communication is established (No at Step S107), and ends the process when the wireless communication is disconnected (Yes at Step S107). .

(Processing flow in the mobile terminal 40)
As illustrated in FIG. 6, the mobile terminal 40 of the in-vehicle system 1 receives the operation information from the in-vehicle device 10 after the wireless communication is established with the in-vehicle device 10 (Yes in Step S201) (Yes in Step S202). ) It is determined whether or not the vehicle is traveling from the recently received traveling state (step S203).

  Subsequently, when it is determined that the vehicle is traveling from the recently received traveling state (Yes in step S204), the portable terminal 40 determines whether or not the received operation information is regulated with reference to the regulation information DB 45b. (Step S205 and Step S206).

  When the received operation information is regulated (Yes at Step S206), the mobile terminal 40 transmits a response indicating that the operation is rejected to the in-vehicle device 10 or a sound indicating that the operation is rejected. Or an image message is output to the speaker 43 or the display operation unit 44 (step S207). When the received operation information is not regulated (No at step S206), an operation corresponding to the received operation information is performed. The result is transmitted to the in-vehicle device 10 or the result is output to the speaker 43 and the display operation unit 44 (step S208).

  Returning to step S204, when it is determined that the vehicle is not running from the recently received running state, that is, the vehicle is stopped (No at step S204), the portable terminal 40 performs an operation corresponding to the received operation information, The result is transmitted to the in-vehicle device 10, or the result is output to the speaker 43 and the display operation unit 44 (step S208).

[Effects of Example 1]

The traveling determination result (running or stopped) that determines the state may be transmitted, and the mobile terminal 40 may perform the restriction control when the received traveling determination result is traveling.

  Specifically, the in-vehicle device 10 acquires the traveling state of the vehicle from various sensors of the vehicle control system unit 20 at predetermined intervals, and determines whether the vehicle is traveling or stopped. And the vehicle equipment 10 transmits the determined result to the portable terminal 40, and the portable terminal 40 performs restriction control with reference to the restriction information DB 45b when the received traveling determination result is traveling.

[Regulation judgment]
For example, in the first embodiment, the example in which the restriction control is performed with reference to the restriction information DB 45b when the mobile terminal 40 is running is described. However, the present invention is not limited to this, and the vehicle is mounted on the vehicle. The apparatus 10 can also perform restriction control.

  Specifically, the in-vehicle device 10 may hold the restriction information DB 45b and perform the restriction control executed by the mobile terminal 40 as described in the first embodiment. By doing so, even if the mobile terminal 40 itself has been subjected to unauthorized modification that cancels the regulation set in advance by law, the regulation can be performed on the in-vehicle device side.

[Mobile devices under regulation]
For example, the mobile terminal 40 of the in-vehicle system 1 disclosed in the embodiment can determine that the vehicle is “running” from the traveling state acquired from the in-vehicle device 10 or the vehicle is “running” from the in-vehicle device 10. When it is received, control is performed to turn off the backlight of the mobile terminal 40 itself. By doing so, it is possible to visually notify the user that the operation is being restricted, and it is possible to further prevent the user from performing unnecessary operations.

[System configuration, etc.]

All or a part can be automatically performed by a known method. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters (for example, FIG. 4) shown in the document and drawings are arbitrarily changed unless otherwise specified. be able to.

  Each component of each illustrated device is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. It can be configured by integrating (for example, integrating the display control unit 18 and the operation information transmitting unit 19). Further, all or any part of each processing function performed in each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware by wired logic.

[program]
The operation restriction control method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program can be distributed via a network such as the Internet. The program can also be executed by being recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, an MO, and a DVD and being read from the recording medium by the computer.

  As described above, the in-vehicle system according to the present invention is useful for a system including an in-vehicle device having a display unit mounted on a vehicle and a mobile terminal device connected to the in-vehicle device by wireless communication. When the vehicle is running, it is suitable for suppressing unnecessary operations and promoting safe driving.
