Description

  The present invention relates to an in-vehicle device operation system in which a terminal operates an in-vehicle device, and particularly relates to an in-vehicle device operation system in which a terminal reads operation information of the in-vehicle device from a storage unit and operates the in-vehicle device.

  As a result of the aggressive introduction of advanced technology to vehicles, the functions and digitization of vehicles have advanced, and various electronic devices have been mounted on vehicles. For example, not only in-vehicle devices related to vehicle control such as laser cruise using electronic devices but also in-vehicle devices related to AV devices such as Blu-ray discs have been introduced.

  Instrument panels that are easy for the driver to operate are equipped with dedicated hard keys for each of these various in-vehicle devices, but since many hard keys are installed in a limited space, there are many hard keys. It is too difficult for the driver to search, the hard key is small and difficult to press, and the hard key is not visible from the driver.

  Further, when the functions increase corresponding to the hard keys, there is a disadvantage that the driver does not know what function the hard keys are switched to. Although the function name may be printed on the key top of the hard key, it is becoming difficult for the driver to read the notation because the hard key has been downsized.

  For example, in a navigation system, an appropriate soft key is arranged for each in-vehicle device on a display device integrated with a touch panel, thereby supporting diversification of in-vehicle devices. However, this method increases the cost of screen design and screen hierarchy. In addition, the navigation system is expensive and difficult to introduce.

  In addition, the multi-switch that assigns multiple functions to one hard key can cope with the diversification of in-vehicle devices, but the driver must grasp the relationship between the number of presses and the function and operate it. The nature will decline.

  It is also conceivable to use an external remote controller. For example, a navigation system integrated with an AV device often includes a remote control. However, since this remote controller can only operate the navigation system, the number of remote controllers increases as the number of in-vehicle devices mounted and the number of functions of the in-vehicle devices increase.

  Here, it is conceivable to use a general-purpose device as an operation means (for example, see Patent Document 1). Patent Document 1 discloses a barcode display medium that reads a barcode with a mobile phone and operates a designated digital home appliance according to an information code described in the barcode.

JP 2004-110148 A

  However, the barcode display medium described in Patent Document 1 has a problem in that no consideration is given to barcode reading support. In order to read the bar code, if the image sensor is not properly arranged with respect to the bar code, it is easy to cause an imaging error such as being out of focus or not capturing the entire bar code on the image sensor. However, Patent Document 1 only describes reading a barcode corresponding to each digital home appliance such as a television and a microwave oven other than an air conditioner. For this reason, there is a possibility that it is troublesome for the driver to read the barcode with the mobile phone.

  In particular, it is often difficult for the driver to adjust the position of the mobile phone so that the bar code is correctly photographed while riding the vehicle.

  An object of the present invention is to provide an in-vehicle device operation system that allows a vehicle occupant to easily read a barcode on a terminal and operate an in-vehicle device in a limited space around a driver seat. And

  In view of the above problems, the present invention provides a terminal provided with a means for reading operation information stored in a storage means, a communication device that receives an operation signal from the terminal, and a control device that controls equipment based on the operation signal The operation signal generated based on the received operation and the operation information by the terminal that has read the operation information of the in-vehicle device from the storage means displayed or embedded in the vehicle interior. Is a vehicle-mounted device operation system that transmits the information to the communication device, and includes a holding unit that holds the terminal at a position where the operation information can be read from the storage unit.

  A vehicle occupant can easily read the barcode on the terminal and provide easy-to-understand usage and operation systems in a limited instrument panel space. Conventionally, the design is limited by hardware or display, but the instrument panel can be designed flexibly.

It is an example of the figure explaining the outline of a vehicle equipment operation system. It is an example of the schematic block diagram of a vehicle equipment operation system. It is an example of the figure explaining the relative position of an operation means and a barcode or an IC tag in the side sectional view of a guide rail. It is an example of the figure which shows the relationship between the front view of a guide rail, and a side positioning means. It is an example of the figure explaining the use condition of an operation means. It is a figure which shows an example of the switch of vehicle-mounted apparatus, and operation description. It is a figure which shows an example of a selection menu display screen.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is an example of a diagram illustrating an outline of an in-vehicle device operation system 100 according to the present embodiment. A mobile phone is placed on a guide rail 21 formed on the instrument panel. For example, the guide rail 21 is formed so as to be recessed in a concave shape from the periphery thereof, and the relative position between the photographing means 23 and each barcode 22 is easily determined by sliding the mobile phone along the guide rail 21. .

  Therefore, the driver (hereinafter, the driver includes passengers in the front passenger seat and the rear seat) simply places the mobile phone in the recess and places the mobile phone in a suitable place for reading the barcode 22. Can be placed. Further, when reading another bar code 22, it is only necessary to slide the mobile phone of the guide rail 21, so that a plurality of bar codes 22 can be easily read by the mobile phone.

FIG. 2 is an example of a schematic configuration diagram of the in-vehicle device operation system 100. The in-vehicle device operation system 100 includes an operation unit 11 and a vehicle side device 20. The operation means 11 has a display 15 and can read the barcode 22 or the IC tag. Examples thereof include a mobile phone, a smartphone, a PDA (Personal Digital Assistant), and a UMPC (ultra mobile PC). In addition, when a smart key (registered trademark; hereinafter referred to as an electronic key) having several hard keys has a function of reading the display 15, the barcode 22 or the IC tag, the electronic key can be used as the operation means 11. Good.

  The vehicle-side device 20 includes a communication device 12, an air conditioner operating device 13, and an air conditioner main body 14. The communication device 12 has, for example, the following device as a substance.

[Communication device 12]
When the operation means 11 is a mobile phone: Bluetooth (registered trademark) communication device (for hands-free calling) or infrared communication device
When the operation means 11 is an electronic key: an electronic key communication device
When the operation means 11 is a mobile phone and the communication device 12 is a Bluetooth (registered trademark) communication device In this case, the mobile phone also needs to have a Bluetooth (registered trademark) communication device (hereinafter referred to as a BT communication device). When two BT communication devices communicate with each other, it is necessary to pair them (displaying the initial setting screen on the display 15 of the mobile phone and inputting a pass key (also called a pass code, PIN code, etc.)) is there. In addition, when boarding the own vehicle, since a hands-free call etc. should already be able to communicate, the pairing work may be omitted.

  In BT communication, use cases that can be used by communication are defined as profiles. Both BT communication apparatuses can communicate with each other by following the same profile. Use cases of the present embodiment are operations of various devices. For such a use case, HID (Human Interface Device Profile) is known. For audio devices, AVRCP (Audio / Video Remote Control Profile) is known. The mobile phone and the BT communication device of the communication device 12 specify the profile to be used and communicate according to the profile. Hereinafter, a signal for controlling the in-vehicle device transmitted from the operation means 11 to the communication device 12 is referred to as control signal information.

When the operation means 11 is a mobile phone and the communication device 12 is an infrared communication device In this case, the mobile phone also needs to have an infrared communication device. Infrared communication devices convert infrared emission pulses into digital data and communicate with each other on the basis of a modulation method defined in the IrDA physical layer standard (IrSIR, IrMIR, etc.). In infrared communication, procedures such as device discovery, access control, logical path establishment, flow control, and data division reconfiguration are standardized from the second to fourth layers based on the OSI basic reference model. Yes. In the fifth layer, IrMC (Infrared Mobile Communication) corresponding to applications such as data exchange is standardized. When the application on the mobile phone side generates control signal information and calls a service provided by the firmware of the fifth layer, the infrared communication device of the mobile phone transmits the control signal information to the infrared communication device of the communication device 12 by infrared communication. It becomes possible to transmit.

When the operation means 11 is an electronic key and the communication device 12 is an electronic key communication device A vehicle equipped with an electronic key forms an electronic key detection area at a predetermined distance from the outside of the door and around the driver's seat. Specifically, the electronic key communication device periodically transmits a request radio wave, and the electronic key transmits a response radio wave to the electronic key communication device in response to the request radio wave.

  In this embodiment, the control signal information is transmitted from the electronic key to the electronic key communication device triggered by the occupant pressing the key of the electronic key. By carrying out like this, control signal information can be transmitted only when a passenger | crew operates a vehicle-mounted apparatus, and power consumption can be suppressed.

[Air conditioner operation device 13, air conditioner body 14]
The air conditioner operating device 13 is a device that receives an air conditioner operation by the driver and operates the air conditioner main body 14. The operation content provided by the air conditioner operating device 13 is, for example, temperature setting, air volume setting, air blowing port selection, Auto setting (automatic selection of air volume, air blowing port, and blowing port except for temperature) and the like. .

  Conventionally, hard keys corresponding to these operations have been provided on the instrument panel, or soft keys have been generated on the touch panel. Even in this embodiment, the air-conditioner can be operated by hard keys or soft keys. When the driver operates the air conditioner from the hard key or the soft key and sets the temperature, for example, the air conditioner operating device 13 determines the refrigerant discharge amount of the compressor of the air conditioner body 14 according to the difference between the current room temperature and the set temperature. The heating amount by the heater core, the valve opening amount of the evaporator that vaporizes the refrigerant, and the like are determined.

  When the driver operates from the operation means 11, the air conditioner operating device 13 controls the air conditioner main body 14 in the same manner without distinguishing from the operation by the hard key or the soft key.

[Information stored in barcode 22 or IC tag]
Information included in the barcode 22 or the IC tag will be described. The barcode 22 may be a one-dimensional barcode instead of a two-dimensional code. A QR code (registered trademark) is known as the bar code 22.

  Further, when the barcode 22 is affixed to the instrument panel, the design may be deteriorated. Therefore, when the barcode 22 is used as a storage medium, the barcode 22 may be printed with ink that is invisible to the naked eye. For example, in a normal state, the barcode 22 is printed with a transparent or light emitting paint of the same color as that of the instrument panel, and when the operation means 11 reads the barcode 22, the operation means 11 irradiates ultraviolet rays or black light. By doing so, it becomes easy to attach the barcode 22 without deteriorating the design. Further, the barcode 22 may be hidden by a cover or the like.

The bar code 22 or the IC tag includes information for communicating with the communication device 12 and information for operating the in-vehicle device (for example, information for instructing the air conditioner operation device 13 to operate the air conditioner main body 14). It is remembered. One barcode 22 may include information only for one operation target vehicle-mounted device, and one barcode 22 may include information of a plurality of operation target vehicle-mounted devices. In the case of an IC tag, since the storage capacity is large, one IC tag can store information on a plurality of on-vehicle devices to be operated.
When the communication device 12 is a BT communication device Name of the operation target, required profile, list of functions that can be set for the in-vehicle device to be operated, control signal information of each function that can be set for the in-vehicle device to be operated When the communication device 12 is an infrared communication device: name of the operation target, list of functions that can be set for the in-vehicle device to be operated, control signal information of each function that can be set for the in-vehicle device to be operated “name of the operation target” These are, for example, air conditioners, AV devices, various windows, and the like. The “necessary profile” is HID for an air conditioner, and AVRCP for an AV device. For example, in the case of an air conditioner, the list of functions that can be set for the in-vehicle device to be operated includes temperature setting, driver seat temperature setting, passenger seat temperature setting, rear seat temperature setting, outdoor temperature display, and air cleaning. Function, etc.

  The “control signal information of each function that can be set for the in-vehicle device to be operated” is, for example, “function identification information + set value”. For example, function identification information is predetermined, the temperature setting is “A”, the driver seat temperature setting is “B”, the passenger seat temperature setting is “C”, the rear seat temperature setting is “D”, The identification information of the function for instructing the operation from the operation means 11 is defined, such as “E” for the display of the outside air temperature and “F” for the air purification function ON. Further, since the set value is a temperature in this case, the set value is a numerical value corresponding to a unit of temperature, for example, “25” or the like. Therefore, the operation means 11 should just transmit control signal information like "A + 25" to the communication apparatus 12 side according to a driver | operator's operation.

  Note that “control signal information of each function that can be set for the in-vehicle device to be operated” is not stored in the barcode 22 or the IC tag, but after communication is established between the operation unit 11 and the communication device 12, The operation means 11 may be acquired from the air conditioner operation device 13 via the communication device 12. For example, this is effective when the in-vehicle device to be operated has many functions and cannot be stored in the barcode 22 or the IC tag.

[Application of the operation means 11]
The operation unit 11 includes at least one of a photographing unit 23 that reads and decodes the barcode 22 and an IC tag reading unit that reads an IC tag. In addition, an application for displaying the operation screen is stored, and a CPU for executing the application is included.

  When reading the barcode 22, the driver starts up the application in advance, and when reading the IC tag, the operation unit 11 reads the IC tag so that the application is automatically started up. The application automatically reads the barcode 22 and the IC tag without any driver operation.

  The application displays the operation screen of the in-vehicle device to be operated on the display 15, accepts the driver's operation, converts the operation content into control signal information, and transmits it to the communication device 12. The application specifies screen data for generating a screen from the “name of operation target” read from the barcode 22 or the IC tag. If the “name of the operation target” is “air conditioner”, the application reads the screen data of the operation screen of the air conditioner.

  In addition, the application determines the operation button based on the “list of functions that can be set for the operation target in-vehicle device” in order to capture the function name in the screen data. Text data, symbols, icons, etc. are displayed on the operation buttons. If the “list of functions that can be set for the in-vehicle device to be operated” is the set temperature, the text data is, for example, “increase” and “decrease”, and the symbols are “<”, “>”, and the like. The correspondence between these lists and operation buttons is previously stored as table data by the application.

  Then, the application displays on the display 15 a screen including “operation target name”, “function name”, and operation buttons. In the example of FIG. 1, “driver seat temperature setting (function name)” “<” “>” is displayed.

  When operating the in-vehicle device to be operated, it is preferable to display the current setting on the display 15. For this reason, the application determines that the current setting should be acquired from the “name of the operation target”, and requests the communication device 12 to transmit the current setting state. That is, the current set temperature, the current set temperature for the driver's seat, the current set temperature for the front passenger seat, the current set temperature for the rear seat, the outside air temperature, and the on / off state of the air purifying function are requested. By doing so, the application can acquire “current set temperature” and the like.

  Then, the application displays the acquired set temperature in association with the function displayed on the operation screen (the function of “driver seat temperature setting” in the case of FIG. 1A). In the example of FIG. 1A, “25” is displayed.

  The driver grasps the driver seat temperature setting screen from the “driver seat temperature setting” drawn on the display 15, grasps the current set temperature from the acquired set temperature, and starts from “<” “>”. It can be understood that the temperature can be raised or lowered by pressing this hard key. Further, if the operation means 11 is compatible with a touch panel, “<” “>” on the display 15 can be operated as it is. When the driver presses the hard key or the display 15, the application increases or decreases the value of the displayed set temperature.

  For example, when the driver presses a “decision” button, the application accepts an operation of “XX degrees” for a function of “set temperature of driver seat”. The application transmits, for example, control signal information “B + OO” to the communication device 12 based on “control signal information of each function that can be set for the in-vehicle device to be operated”. Since the communication device 12 sends the received control signal information to the air conditioner operation device 13, the air conditioner operation device 13 controls the air conditioner body 14 so that the temperature of the driver seat becomes the set temperature based on the control signal information.

  When the operating means 11 is slid along the guide rail 21 described below, the operating means 11 moves by one bar code 22 as shown in FIG. The application reads this barcode 22 and displays the operation screen of the next in-vehicle device corresponding to the barcode 22. In FIG. 1B, the operation screen of the air conditioner operation device 13 is displayed. However, for example, the operation screen of the AV device may be displayed. The relationship between the placement position of the operation means 11 and the operation screen is changed according to the amount of information included in the barcode 22.

[Attachment location of barcode 22 or IC tag]
The barcode 22 or IC tag is affixed to the instrument panel or center cluster. Moreover, you may affix on the key top of a predetermined switch. The bar code 22 and the IC tag of the switch store information for operating the in-vehicle device operated by the driver using the switch.

  Further, instead of attaching the bar code 22, it may be displayed on the liquid crystal display part of the meter panel. In this case, the display position of the barcode 22 can be corrected, or another barcode 22 can be displayed at the same position, and the barcode 22 can be prevented from being displayed in a normal state.

[Guide rail 21]
The guide rail 21 will be described. The guide rail 21 defines a relative position between the casing of the operation unit 11 and the barcode 22 or the IC tag so that the operation unit 11 can reliably read information from the barcode 22 or the IC tag.

  FIGS. 3A to 3C are examples of diagrams for explaining the relative positions of the operating means 11 and the barcode 22 or the IC tag in the side cross-sectional view of the guide rail 21. A step is provided below the instrument panel along the vehicle width direction. In FIG. 3A, four steps are provided, but there may be five or more as long as it is one or more. This step is the guide rail 21. A bar code 22 or an IC tag is attached above the guide rail 21. On the other hand, the operation means 11 has a photographing means 23 or an IC tag reading means at the position shown in the figure. The driver can use the guide rail 21 to adjust the photographing means 23 or the IC tag reading means to the position of the barcode 22 or the IC tag.

  As shown in FIG. 3A, when the operation means 11 is placed on the uppermost stage of the guide rail 21, the position of the barcode 22 or the IC tag is shifted from the position of the photographing means 23 or the IC tag reading means. . Therefore, as shown in FIG. 3 (b), when the driver places the operation means 11 on the third stage of the guide rail 21, the photographing means 23 can photograph the barcode 22, or the IC tag reading means can be the IC tag reading means. The tag can be read.

  When the operation means 11 is a mobile phone, where the photographing means 23 or the IC tag reading means is mounted on the operation means 11 varies depending on the model. By providing a step on the guide rail 21, it becomes easy to deal with various models. . On the other hand, when the operation means 11 is an electronic key, the manufacturer of the vehicle can design where the photographing means 23 or the IC tag reading means is mounted on the operation means 11, so that the guide rail 21 can have one step. .

  Moreover, as shown in FIG.3 (c), you may provide the guide rail 21 also above an instrument panel. If the guide rail 21 is above and below the barcode 22 or the IC tag, the upper part of the operation means 11 can be prevented from coming into contact with the instrument panel. Further, since a space can be provided between the barcode 22 or the IC tag and the photographing means 23 or the IC tag reading means, it is possible to prevent the bar code 22 or the IC tag from being faded. 22 becomes easy to read.

  FIG. 4 shows the relationship between the front view of the guide rail 21 and the side positioning means 24. When the number of in-vehicle devices mounted on the vehicle increases, it is considered that a plurality of barcodes 22 or IC tags are attached to the instrument panel. Therefore, the guide rail 21 has side positioning means 24 that determines the position of the operation means 11 in the vehicle width direction as well as the vertical direction.

  The side positioning means 24 is a protrusion provided on the step of the guide rail 21. The height with respect to the level | step difference of a protrusion is about 1-5 mm. In order to move the operating means 11 beyond the lateral positioning means 24 in the vehicle width direction, it is necessary to move the center of gravity of the operating means 11 by this height against gravity. Therefore, when the driver slides the operating means 11 along the guide rail 21 in the vehicle width direction, the operating means 11 is locked and its position is determined.

  Further, the protrusions that are the side positioning means 24 may be urged upward from the guide rail 21 with an elastic body such as a spring or rubber, or may be provided with a member such as rubber that reversibly deforms. . In such a case, when the operating means 11 is slid strongly, the side positioning means 24 strokes or deforms in the guide rail 21, so that the operating means 11 is locked by the side positioning means 24 by the driver's force. It can be made to pass through and the operability is improved.

  The side positioning means 24 is arranged so that the photographing means 23 or the IC tag reading means of the operation means 11 can photograph at least the barcode 22 or read the IC tag when the side surface of the operation means 11 comes into contact. The When the width of the operation means 11 is 5 cm and the photographing means 23 or the IC tag reading means of the operation means 11 is arranged at the approximate center in the width direction, the side positioning means 24 is positioned from the center of the barcode 22 or the IC tag. It is arranged at a position of about 2.5 cm in the width direction. Since the position of the operation means 11 on the guide rail 21 in the vehicle width direction is sufficient if one of the left side and the right side is determined, the side positioning means 24 is spaced sufficiently wider than the width of the mobile phone (for example, 6 cm). Provided. The driver only has to slide until either the left side or the right side of the operation means 11 contacts the side positioning means 24.

  In particular, in the case of the barcode 22, there is a possibility that the tolerance of displacement of the relative position between the photographing means 23 and the barcode 22 may be narrow. Therefore, a plurality of barcodes 22 storing the same information may be arranged in the vehicle width direction. A plurality may be arranged in the vertical direction. This makes it easier for the photographing means 23 to photograph the barcode 22.

  Further, it is not necessary that the top-and-bottom relationship of the operation means 11 and the vertical relationship of the barcode 22 or the IC tag match. As is well known for IC tags, there are almost no restrictions on the orientation of the IC tag and the orientation of the IC tag reader, and the barcode 22 can be decoded even if the photographing means 23 photographs the barcode 22 upside down. Because. When the driver places the top of the operation means 11 upside down on the guide rail 21, the application detects the placement direction by the G sensor in the operation means 11 and reverses the direction of the operation screen displayed on the display 15. To do.

  Note that the driver may or may not know the correspondence between the barcode 22 or the IC tag and the in-vehicle device to be operated. In order to grasp, for example, the name of the vehicle-mounted device to be operated or an icon sticker is attached to the barcode 22 or the IC tag. Even without such a seal, the driver can grasp the vehicle-mounted device to be operated simply by sliding the operating means 11 along the guide rail 21 and viewing the display 15.

  As described above, the in-vehicle device operation system 100 according to the present embodiment displays a screen for operating the in-vehicle device on the operation unit 11, so that the operation content can be displayed on a large screen even when the in-vehicle space of the hard key is limited. It can be displayed and operated. The bar code 22 is relatively small, and unlike the hard key, no internal wiring is required. Therefore, even when affixed to the instrument panel, the bar code 22 does not occupy much space. Further, by providing the guide rail 21, the operating means 11 can be placed at an appropriate position with respect to the barcode 22 or the IC tag with almost no line of sight movement of the driving driver.

  The first embodiment is characterized in that the operating means 11 is placed on the guide rail 21, but the in-vehicle device cannot be operated unless the operating means 11 is necessarily placed on the guide rail 21.

  FIG. 5 is an example of a diagram illustrating the usage status of the operation unit 11 of the present embodiment. When the vehicle is stationary, it is not difficult for the driver to photograph the bar code 22 with the operation means 11, and information can be read by simply bringing the operation means 11 closer to the IC tag.

  In addition, after the operation unit 11 reads the barcode 22 or the IC tag on the guide rail 21, the operation unit 11 and the communication device 12 can communicate even if the driver holds the operation unit 11 with his / her hand. . When the communication device 12 is an infrared communication device, the driver needs to point the light emitting / receiving element of the operation means 11 toward the light emitting / receiving element on the communication device 12 side, but this operation is not difficult even during traveling. When the communication device 12 is a BT communication device, the driver does not need to consider even the distance between the operation means 11 and the communication device 12.

  Therefore, after the operation means 11 reads the barcode 22 or the IC tag, the driver can hold and operate the operation means 11.

  In the first or second embodiment, it is assumed that the operation unit 11 is operated. However, instead of operating the in-vehicle device from the operation unit 11, an operation description of the in-vehicle device may be displayed on the operation unit 11. In this case, the driver can understand the function and operation method of the in-vehicle device by reading the operation explanation displayed on the operation means 11, and can directly operate the in-vehicle device.

  FIG. 6 is a diagram illustrating an example of a switch and operation description of the in-vehicle device. When the PCS (Pre-Crash Safety) is mounted on the vehicle, the PCS switch 25 may be disposed. A barcode 22 is affixed to the key top of the PCS switch 25. An IC tag may be embedded instead of the barcode 22.

  When the photographing unit 23 of the operation unit 11 captures and decodes the barcode 22, the application displays the operation content on the display 15 as illustrated. In the figure, the explanation of the operation of the PCS is displayed as “a device that sounds a warning sound and assists the brakes when approaching the vehicle ahead. The system is currently in operation mode”. The driver can read the operating instructions and turn the PCS switch 25 off or on.

  An explanation of the functions of such an in-vehicle device is described in the instruction manual. However, by arranging the barcode 22 or the IC tag on the switch as shown in the figure, it is possible to save the driver from having to read the instruction manual. Therefore, the usage rate of the in-vehicle device can be improved. In addition, since the instruction manual can be easily bound and the distribution of the instruction manual can be omitted, resource saving can be achieved.

  In addition, the vehicle equipment operation system 100 of a present Example can be vehicle-mounted with the vehicle equipment operation system 100 of Example 1, and can also be vehicle-mounted alone.

  As described in Example 1 or 4, the in-vehicle device operation system 100 according to the present embodiment can operate various in-vehicle devices from the operation unit 11. However, since the size of the display 15 of the operation means 11 is also limited, it is difficult to display the operation screens of all the in-vehicle devices at once. Therefore, a description will be given of the in-vehicle device operation system 100 that allows a frequently used operation screen to be called preferentially.

  In the present embodiment, the application is once acquired from the barcode 22 or the IC tag, the name of the operation target, the necessary profile, a list of functions that can be set for the in-vehicle device to be operated, and the in-vehicle device to be operated. Control signal information for each settable function is stored.

  And every time a driver operates, an application specifies the function operated with respect to the name of operation object, and the vehicle-mounted apparatus of operation object, and counts the frequency | count of operation. For example, when the driver sets the temperature of the driver's seat from the operation means 11, the application counts the number of times of setting the temperature of the driver's seat of the air conditioner as N1 times. Therefore, the application detects and holds the number of operations (N1 + N2 +...) Of each in-vehicle device and the number of operations N1 for each function of each in-vehicle device.

  When the driver starts up the application, that is, when the driver starts up for reading the barcode 22, for example, or when the driver operates and starts up, the application displays a selection menu in order of frequency of operation. When the application is automatically started by reading the IC tag, an operation screen for the in-vehicle device stored in the IC tag may be displayed, or a selection menu corresponding to the operation frequency may be displayed. .

There are the following display modes using the operation frequency.
-A menu for calling the functions of the in-vehicle device is displayed in descending order of the number of operations in the past predetermined period.
Similarly, a menu for calling up the operation screen of the in-vehicle device is displayed in descending order of the number of operations in the past predetermined period.
・ Display the menu for calling the functions of the in-vehicle device in the order of the history of operation.

  In addition, the driver may customize the selection menu display screen by freely discarding the menu for calling the operation screen or function of the in-vehicle device to be displayed.

  FIG. 7 is a diagram illustrating an example of a selection menu display screen. The selection menu display screen of FIG. 7 is a selection menu display screen that “displays a menu for calling functions of the in-vehicle device in descending order of the number of operations in a predetermined period in the past”. For example, “driver seat temperature setting”, “passenger seat temperature setting”, and “PCS SW” are displayed in order from the top of the display 15 as functions having a large number of operations. By scrolling the screen, another menu is displayed.

  The driver can select a menu from frequently used functions, and can display an operation screen of the target function at an early stage. The driver may press the soft key as it is from the display 15 of the touch panel, or may select the selection menu using the upper and lower hard keys provided in the operation means 11.

  In this way, by storing the information acquired from the barcode 22 or IC tag and counting the number of operations, not only the operation screen of each in-vehicle device is displayed, but also a menu of functions frequently used by the driver is given priority. It is possible to customize the display.
