  By the way, a person who frequently uses the smartphone may drive the vehicle, and in this case, there is a case where the user desires to operate the smartphone in the vehicle. However, since smartphones are premised on the fact that the equipped second display is relatively small and is operated in a state close to the eyes, there are a large number of display items, and there are also pictograms to be displayed. It will be quite small.

  From such a situation, it is conceivable to display the display content of the second display equipped in the smartphone on the relatively large first display mounted on the vehicle. However, operating a smartphone while driving is not preferable for safe driving. In addition, since the number of display items displayed on the second display of the smartphone is large and the display of each display item is considerably small, the display content of the second display is displayed on the large first display mounted on the vehicle. Even so, it takes time for the driver to identify the display items.

  The present invention has been made in view of the circumstances as described above, and its purpose is to improve the operability of a smartphone by a driver and improve the identification of display contents on the smartphone. Is to provide.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1,
A first display mounted on the vehicle and provided at a position visible to the driver;
A command switch mounted on the vehicle and manually operated by the driver;
Control means mounted on a vehicle and controlling screen display of the first display in response to an operation of the command switch;
A smartphone as a portable information terminal having a second display, which is detachably connectable to the control means,
With
The control means causes the command switch to function for screen operation of the second display in a state where the smartphone is connected, and reduces the number of display items for a plurality of display items displayed on the second display. Displayed on the first display in a state of being
It is like that.

  According to the said solution technique, the operativity of a smart phone will be improved by operating a smart phone using the command switch provided in the vehicle. In addition, since the number of display items that is reduced from the number of display items on the second display of the smartphone is displayed on the first display mounted on the vehicle, the identification of the display items is also improved. Thus, the smartphone can be operated in a state in which the driver gazes ahead.

A preferred mode based on the above solution is as described in claim 2 and the following. That is,
When the frequency of use of the display screen displayed on the second display is high, the control means displays a plurality of display items on the first display in the form of icons. Correspondence). In this case, the icon display has higher distinguishability than the character display, and particularly when the proficiency level is increased, the distinguishability is dramatically improved, so that the driver does not care about the operation of the smartphone. Preferred above. Particularly, since the icon display is used when the usage frequency is high, it is preferable to identify the icon desired by the driver from a plurality of icons displayed at the same time in a very short time.

  When the frequency of use of the display screen displayed on the second display is low, the control means displays a plurality of display items on the first display in a column character display format in which character displays are arranged vertically. (Corresponding to claim 3). In this case, even in the same character display, the column display has a higher discriminability than the row display, and is preferable as a display mode in the case of performing character display.

The second display is a touch panel type. When the fingertip is moved up and down while touching the second display, up and down scrolling is performed. By moving left and right, left and right scrolling is performed. Switch to the selection screen corresponding to the specific display item that is located,
The command switch individually has an operation for switching to a selection screen corresponding to a specific display item for scrolling up and down and scrolling left and right of the second display.
(Corresponding to claim 4). In this case, it is preferable for operating the smartphone with the same feeling as operating the smartphone directly using the command switch.

When the use frequency of the display screen displayed on the second display is high, the control means displays a plurality of display items in the first display in the form of icons, respectively, while being displayed on the second display. When the display screen is not used frequently, a plurality of display items are displayed on the first display in a column character display format in which character displays are arranged vertically,
The command switch is capable of forward / backward tilt operation, left / right tilt operation, rotation operation and push operation,
When a plurality of display items are displayed in icon form on the first display, the control means performs vertical scrolling according to the front / rear tilt operation of the command switch, and performs horizontal scrolling according to the left / right tilt operation. , Switch to the selection decision screen according to the push operation,
When a plurality of display items are displayed in the column character display format on the first display, the control means scrolls up and down according to the rotation operation of the command switch and goes to the selection determination screen according to the push operation. Switching
(Corresponding to claim 5). In this case, when the icon is displayed, the desired icon can be quickly selected by tilting up / down / up / down of the command switch, that is, by operating in the same manner as a touch panel operation on a smartphone. . Further, when displayed in the column character display format, a desired character display can be selected promptly by rotating the command switch.

  The command switch is disposed on the center console in front of the armrest, the driver rests the arm on the armrest, and the wrist is positioned near the wrist at the tip of the armrest. It can be operated by the fingertips of the above (corresponding to claim 6). In this case, the driver can easily and clearly grasp the position of the command switch without visually moving the tip of the wrist with the arm resting on the armrest, and visually confirm the command switch. You can operate the screen without having to do it.

  On the center console, a plurality of shortcut keys for displaying a specific display screen on the second display is arranged around the command switch (corresponding to claim 7). . In this case, switching to a desired screen display state can be performed at once. Further, since the shortcut key is in the vicinity of the command switch, it is easy to confirm the position of the shortcut key.

  When the smart phone is not connected, the control means causes the command switch to function as a screen operation on the first display related to a vehicle-mounted device (corresponding to claim 8). In this case, the command switch can be used for smartphone screen operation as needed, usually functioning as a screen operation for on-vehicle equipment, and a dedicated switch for smartphone operation needs to be provided separately. It will not be.

  In FIG. 1 showing the vicinity of a driver's seat of an automobile as a vehicle, 1 is an instrument panel, 2 is a front window glass, and 3 is a steering handle. In FIG. 1, a left-hand drive vehicle is shown.

  A front end portion of the center console 4 extending in the vehicle body front-rear direction is connected to a center portion in the vehicle width direction of the instrument panel 1. On the center console 4, an operation knob 5 for operating the transmission, a switch panel unit 6, and an armrest 7 are sequentially arranged from the front side to the rear side. A parking brake lever 8 is provided on the steering wheel 3 side of the center console 4.

  Details of the switch panel section 6 are shown in FIGS. The switch panel unit 6 is provided with a plurality of switches as described below. First, a dial switch 10 as a command switch is provided. The dial switch 10 is capable of forward / backward tilt operation, left / right tilt operation, rotation operation around the vertical axis, and push-down operation (push operation).

  Three push-down switches 11, 12, and 13 are disposed along the vehicle width direction so as to be positioned immediately before the dial switch 10. Further, a push-down switch 14 is disposed in the immediate vicinity of the dial switch 10 on the left side, and a push-down switch 15 is disposed in the immediate vicinity of the right side.

  The switch panel unit 6 is further provided with a volume adjustment switch 20. The volume adjustment switch 20 is arranged on the right side in the arrangement direction of the push-down switches 11 to 13. That is, the volume adjustment switch 20 is disposed on the opposite side of the steering handle 3 and the parking brake lever 8 with the dial switch 10 interposed therebetween.

  The position of the volume adjustment switch 20 in the front-rear direction is set so as to overlap the length range of the three push-down switches 11-13, that is, in a range where the push-down switches 11-13 are extended in the vehicle width direction. Further, a part of the volume adjustment switch 20 is configured such that the front end portion of the dial switch 10 and the position in the front-rear direction overlap (the rear portion of the volume adjustment switch 20 is located within the extension range of the dial switch 10 in the vehicle width direction). ).

  The dial switch 10 is formed in a substantially cylindrical shape with a protruding height of, for example, about 2 to 3 cm, for example, because of the rotational operation. The dial switch 10 has a large diameter so that it can be easily rotated with the palm of the hand or with the three fingers of the thumb, forefinger, and middle finger (for two to four adult fingers). For example, about 4 to 6 cm).

  On the other hand, the volume adjustment switch 20 is also adjusted in volume according to the rotation operation, and has a substantially cylindrical shape with a protruding height of about 2 to 3 cm, for example. The volume adjustment switch 20 is sufficiently smaller in diameter than the dial switch 10 so that it can be easily rotated with fingers (especially the thumb and forefinger) (for example, a diameter of about one adult finger, for example, 1 About 2 cm). The volume adjustment switch 20 is in the vicinity of the dial switch 10 but has a small interval (for example, about 2 to 3 cm) so that a finger (one finger of an adult) is not sandwiched between the dial switch 10 and the dial switch 10. The position is set.

  The push-down switches 11 to 15 are sufficiently lower in height than the dial switch 10 and the volume control switch 20 (for example, the protruding height is about 2 to 5 mm). Each of the push-down switches 11 to 15 has a relatively large area so that it can be easily pushed down with one fingertip (for example, the width in the vehicle width direction is about 1.5 to 2.0 cm, The direction length is, for example, about 2 to 3 cm). However, of the three push-down switches 11 to 13 disposed immediately before the dial switch 10, the central push-down switch 12 is a width of the home switch because it is used frequently as will be described later. The protrusion height is larger than that of the push-down switches 11 and 13. In order to distinguish the central push-down switch 12, it is possible to clearly distinguish it from the push-down switches 11 and 13, for example, by forming a recess or a protrusion on the upper surface thereof.

  The dial switch 10 and the front end of the armrest 7 are relatively close to each other. Specifically, as shown in FIG. 4, when the driver's arm 30 (right hand in the embodiment) is placed on the armrest 7, the palm is dialed when the elbow is fixed and the wrist is bent downward. It is positioned immediately above the switch 10 so that the vicinity of the base of the finger is positioned at the front end of the dial switch 10.

  As shown in FIG. 4, the push-down switch 11 can be easily pushed down with the index finger 30a by slightly bending the fingertip downward with the palm touching the dial switch 10. Similarly, the push-down switch 12 can be easily pushed down with the middle finger 30b. The push-down switch 13 can be easily pushed down with the ring finger 30c. With the thumb 30d, the push-down switch 14 can be pushed down easily. The push-down switch 15 can be easily pushed down with the little finger 30e. As described above, by providing five push switches 11 to 15 corresponding to the position and number of fingers, the driver has a great effect of learning (storing) the switch operations of the push switches 11 to 15. It will be a thing.

  The upper surfaces of the switches 10 to 16 and 20 are lower than the upper surface of the armrest 7 (for example, the upper surface of the dial switch 10 is lower by about 3 to 10 cm than the upper surface of the tip of the armrest 7). . Thus, the various switches 10 to 16 can be operated in a state where the tip of the wrist naturally hangs down with the arm 30 placed on the armrest 7. From this state, the volume adjustment switch 20 can be operated by moving the hand slightly in the clockwise direction in FIG. 4 around the wrist.

  Referring again to FIG. 1, a thin display (display screen) 40 configured using, for example, a liquid crystal screen is disposed on the instrument panel 1 at the center in the vehicle width direction. A head-up display 41 is disposed on the instrument panel 1 at a position directly in front of the steering handle 3. Each of the displays 40 and 41 is set at a position that can be easily seen by the driver. The display 40 is a first display on which display corresponding to the display content of a smartphone described later is performed.

  As shown in FIG. 1, the center console 4 is equipped with a connection part 35 of the smartphone SM. The smartphone SM and the connection unit 35 are connected using a connection 36 such as a USB cord. Note that the connection is not limited to a wired connection, and can be performed by wireless communication such as Blue tooth (registered trademark).

  The display in the smartphone SM, that is, the second display 37 is a touch panel type, and the vertical scroll is performed by moving the fingertip up and down while touching the second display 37, and the horizontal scroll is performed by moving left and right. In addition, switching to a selection determination screen corresponding to a specific display item where the fingertip is located is performed by a tap operation.

  An example of a control system for screen operations related to the operations of the switches 10 to 16 will be described with reference to FIG. First, U is a controller (control unit) as control means configured using a microcomputer. In a normal time when the smartphone SM is not connected to the connection unit 36, the controller U responds to the operations of the various knowledges 10 to 15, for example, the navigation device 51, the various audio devices 52, and the vehicle-mounted devices such as the TV tuner 53. Control is performed so that the display content corresponding to the operating state is displayed on the first display 40. In addition, the volume of the speaker 54 that is common to the devices 51 to 53 is controlled.

  In a state where the smartphone SM is connected to the connection unit 36, the dial switch 10 and the push-down switches 11 to 15 described above are for operation of the smartphone SM, and the display content of the first display 40 is the second display of the smartphone SM. 37 corresponding to the display contents.

  For the screen operation on the smartphone SM by the dial switch 10, for example, an application (application software) provided by the vehicle manufacturer is downloaded to the smartphone SM. When downloading, the operation signals of the switches 10 to 15 are associated with the touch operation on the second display 37 of the smartphone SM. Specifically, the forward / backward tilt operation of the dial switch 10 is associated with the vertical scroll on the second display 37. The left / right tilt operation of the dial switch 10 is associated with left / right scrolling on the second display 37. The rotation operation of the dial switch 10 is associated with the vertical scroll on the second display 37. The depression (push) operation of the dial switch 10 is associated with determination of a selection candidate on the second display 37 (corresponding to a tap operation on the Dutch panel). The depression operation of each depression switch 11-15 as a shortcut key is matched as a command for selecting a specific screen display in the smartphone SM. On the vehicle side, the switches 10 to 15 are switched for smartphone SM operation (screen operation related to the vehicle-mounted device on the first display 40 is prohibited), while the screen corresponding to the second display 37 on the smartphone SM Switched for operation.

  Next, the screen operation by the operation of the switches 10 to 15 when the smartphone SM is connected to the connection unit 35 will be described with reference to FIGS. 6 to 9. First, FIG. 6 is an initial screen when the smartphone SM is connected to the connection unit 35 in a state where the main menu (home screen) is displayed.

  FIG. 6A shows display contents on the second display 37 of the smartphone SM. FIG. 6B shows the display contents on the first display 40 mounted on the vehicle. In the second display 37, display items consisting of a plurality of (for example, seven) character displays related to the main menu are arranged in a column character display, but the main menu is frequently used. , And icon display (upper and lower two columns, three in each row, a total of six are displayed). Further, the number of display items (the number of icons) displayed on the first display 40 is assumed to be smaller than the number of display items on the second display 37. In addition, about the display item which is not displayed on the 1st display 40, it will be displayed by scroll operation mentioned later.

  In the state of FIG. 6, one of the display items on the first display 40 (the same applies to the second display 37) (initially the display item at the top) is displayed as a selection candidate. The display is performed with an appropriate form of cursor display, such as lighting one display item brighter than the other display items, blinking, or displaying separately.

  In the state of FIG. 6B, for example, when the display item (icon) of “Navi” is blinking and displayed as a selection candidate, the selection candidate is set to 1 by tilting the dial switch 10 to the right. By successively shifting to the right display item and tilting backward, the lower display item is selected. As described above, an arbitrary display item (icon) is selected as a selection candidate by using the front / rear / right / left tilt operation of the dial switch 10.

  In FIG. 6, for example, when the dial switch 10 is pushed in a state where the display item “telephone” is a selection candidate, the display 37 and 40 are switched as shown in FIG. 7. Also in this case, the number of display items on the first display 40 is reduced from the number of display items on the second display 37. The display mode on the second display 37 is a column character display, and since the use frequency of the screen display of FIG. 7 is low, the display mode on the first display 40 is also a column character display. In this column character display state, the selection candidate is changed by rotating the dial switch 10 (forward / reverse operation). Then, by a push operation of the dial switch 10, the screen is switched to a screen (selection determination screen) corresponding to the display item that is a selection candidate.

  When the dial switch 10 is pushed (decision operation) with “phone book” as a selection candidate from the state of FIG. 7, the display contents of the displays 37 and 40 are switched as shown in FIG. In FIG. 8, the display mode on the second display 37 is the column character display. In addition, since the frequency of use of the display items of the “phone book” is low, the display mode on the first display 40 is a column character display.

  When the value frequency of the “phone book” display item is high, the display mode shown in FIG. 9 is used instead of the display mode shown in FIG. That is, the display form on the first display 40 is displayed in the icon format. In addition, in the case of icon display, in addition to the “image” display of the icon, a combination of “character display” that briefly shows the content is displayed.

  10 to 13 are flowcharts for performing the display control (screen operation control) as shown in FIGS. 6 to 9 described above. This flowchart will be described below. In the following description, Q indicates a step.

  First, in Q1 of FIG. 10, it is determined whether or not the smartphone SM is connected to the connection unit 35. If NO in the determination of Q1, in Q2, the display content on the first display 40 according to the operation of the switches 10 to 15 is the content related to the operation of the various on-vehicle devices. When the determination of Q1 is YES, as will be described later, the switches 10 to 15 and the first display 40 are used as related to the smartphone SM.

  FIG. 11 shows control corresponding to Q2 in FIG. That is, in Q11 of FIG. 11, it is determined whether or not the display mode on the first display 40 is an icon format. If the determination in Q11 is YES, in Q12, the display mode corresponding to the icon format is selected. If NO in Q11, the display mode corresponding to the column character display format is selected in Q13.

  An example of control when Q12 in FIG. 11 is selected is shown in FIG. That is, first, at Q21, it is determined whether or not the dial switch 10 has been tilted. When the determination in Q21 is YES, scrolling (change of selection candidates) is performed in Q22 according to the tilt operation.

  After Q22 or when NO in Q21, it is determined in Q23 whether or not the dial switch 10 has been pushed. If NO in Q23, the process returns to Q21.

  If YES in Q23, the display content corresponding to the selection candidate when the dial switch 10 is pushed is selected in Q24, and the usage frequency is updated and stored. Thereafter, in Q25, it is determined whether or not the use frequency of the display content selected this time is higher than a preset use frequency (for example, the use frequency). If the determination in Q25 is YES, in Q26, the screen selected in Q24 is displayed on the first display 40 with the number of display items reduced and in icon form. If NO in Q25, the screen selected in Q24 is displayed on the first display 40 in Q27 with the number of display items reduced and in the column character display format. After Q26 and Q27, the process returns to Q11 in FIG.

  An example of control when Q13 in FIG. 11 is selected is shown in FIG. 13 (corresponding to FIG. 12). That is, first, at Q31, it is determined whether or not the dial switch 10 has been rotated. When the determination in Q31 is YES, in Q32, scrolling (changing selection candidates) is performed in accordance with the rotation operation.

  After Q32 or when NO is determined in Q31, it is determined in Q33 whether or not the dial switch 10 has been pushed. If NO in Q33, the process returns to Q31.

  If the determination in Q33 is YES, in Q34, the display content corresponding to the selection candidate when the dial switch 10 is pushed is selected, and the usage frequency is updated and stored. Thereafter, in Q35, it is determined whether or not the use frequency of the display content selected this time is higher than a preset use frequency (for example, the use frequency). If the determination in Q35 is YES, in Q36, the screen selected in Q34 is displayed on the first display 40 with the number of display items reduced and in icon form. If NO in Q25, the screen selected in Q24 is displayed on the first display 40 in Q27 with the number of display items reduced and in the column character display format. After Q26 and Q27, the process returns to Q11 in FIG.

  Here, when any one of the shortcut keys 11 to 15 is operated, the display contents of the respective displays 37 and 40 are quickly switched to a specific screen display associated in advance. For example, when the push switch 12 is depressed, the home screen, that is, the main menu screen shown in FIG. 6 is switched. The push switch 11 is a shortcut key for displaying a screen for audio selection (audio selection key). The push-down switch 13 is a shortcut key for selecting navigation (navigation key). The push-down switch 14 is a shortcut key for switching the display contents of the displays 37 and 40 to the previous display contents (return key). The push switch 15 is a shortcut key for displaying a screen registered in advance by the driver (favorite key).

  For example, when a map is displayed on the second display 37, the first display 40 can display an enlarged map centered on the position of the host vehicle (the map information of the smartphone SM is mounted on the vehicle). Or more detailed information about at least the vicinity of the current position than the map information of the navigation device 51 being used). Further, when the audio function of the smartphone SM is selected, an icon of the audio operation function or the like (for example, playback stop, fast forward, repeated playback, next song selection, etc.) is displayed on the first display 40. can do.

  Although the embodiments have been described above, the present invention is not limited to the embodiments, and appropriate modifications can be made within the scope of the claims. When the display item displayed on the second display 37 is only the character display, the icon display on the first display 40 corresponds to the display item of the character display when the application is downloaded to the smartphone SM described above. A process for separately associating the icon is performed. Further, even if the function can be selected in the smartphone SM, a program for setting a prohibition condition that prevents execution (realization) of a function that is not preferable during driving may be incorporated in the application. As a 1st display which performs the display according to the display content of the 2nd display 37, it is good also as both the display 41 or both of 40 and 41. FIG.

  An appropriate type of command switch can be adopted. Further, scrolling may be performed by combining tilt operation and rotation operation of the dial switch 10. For example, while making it possible to scroll up and down with a tilting operation in front and back, it is also possible to scroll up and down with a rotating operation, while scrolling left and right with a tilting operation on the left and right, and rotating with a rotating operation, icon display as shown in FIG. These scrolls can be set as appropriate, for example, by performing a rotation operation. The number of the push-down switches 11 to 15 can be set as appropriate, and some or all of them may not be provided. For example, an air-conditioning device can be appropriately selected as a vehicle-mounted device to be controlled for screen display according to the operation of the dial switch 10 and the push-down switches 11 to 15.

  When the smartphone SM is connected to the vehicle, the display content on the second display 37 can be confirmed by the display on the first display 40, so the second display 37 may be turned off. That is, in (a) shown in the upper part of FIG. 6 to FIG. 9, the display 37 of the smartphone SM may be turned off, and in this case, the power consumption of the smartphone SM can be significantly reduced. However, the second display 37 may not be turned off even after connection to the vehicle, or may be turned off after a predetermined time has elapsed after connection to the vehicle.

  The push-down switches 11 to 15 may be configured to be able to operate the in-vehicle device in the same manner as when the smartphone SM is connected to the vehicle even when the smartphone SM is not connected. In this case, it is particularly preferable when the push-down switches 11 to 15 are set for in-vehicle device operation unrelated to the screen operation of the smartphone SM. Further, one of the displays 40 and 41 can be used for the smartphone SM, and the other can be used for screen operation by the push-down switches 11 to 15. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.

  As for this invention, a suitable thing is provided on the smart phone operation by a driver | operator.
