Description

The present invention relates to an in- vehicle electronic device , and is particularly suitable for use in an in-vehicle electronic device that uses a so-called dual view display as a display device so that different images can be seen depending on the viewing direction on one display screen. It is a thing.

  In general, in-vehicle navigation devices detect the current position of a vehicle using a self-contained navigation sensor, a GPS (Global Positioning System) receiver, or the like, read out map data in the vicinity of the vehicle, and display it on a screen. Then, the vehicle position mark indicating the vehicle position is superimposed and displayed at a predetermined location on the screen, so that it can be seen at a glance where the vehicle is currently traveling.

  Most navigation devices have a route guidance function. This route guidance function automatically searches for the route with the lowest cost from the current location to the destination using map data, and uses the searched route as a guidance route to change the color of other roads on the map screen. draw. Further, when the vehicle approaches a guidance intersection on the guidance route within a certain distance, an enlarged view of the intersection is displayed and the intersection is guided to guide the driver to the destination.

When using such a navigation device, it is necessary to perform an operation for giving a desired instruction to the navigation device using a remote controller, a touch panel, or the like. However, it is not desirable from the viewpoint of safety that the driver performs an operation while traveling, and it is prohibited by law. For this reason, the conventional navigation device is configured to limit the acceptance of the operation (deactivate the operation) while it is detected that the vehicle is running (see, for example, Patent Documents 1 and 2).
JP-A-11-281376 JP 2005-49110 A

  However, in the case of a passenger in the passenger seat, although there is no safety problem even during operation while traveling, in the conventional navigation device, operation with respect to the navigation device is completely prohibited during traveling, and the operation can be performed even by the passenger. There was a problem that it could not be done at all.

  In view of such problems, the invention described in Patent Document 1 described above detects the orientation of the video monitor, prohibits the operation when the orientation of the video monitor is facing the driver's seat, and It is configured to allow the operation when the direction is facing the passenger seat. Thereby, even if it is driving | running | working, it is comprised so that operation can be permitted to the passenger of a passenger seat.

In addition, in the case of using a dual view display configured to be able to see different images depending on the viewing direction on one display screen, whether the operator of the touch panel provided on the display is a driver or an assistant There has also been proposed a technique in which whether a passenger is in a seat is detected by a sensor or the like, and the operation content is reflected only on an image corresponding to the detected operator (see, for example, Patent Document 3).
JP 2004-233816 A

  However, the technique described in Patent Document 1 has a problem that the direction of the video monitor must be directed to the passenger seat side in order to allow the passenger to perform operations while traveling.

  Moreover, in the technique of the said patent document 3, it only discloses that a driver | operator and a passenger perform operation with respect to each image | video independently, but a passenger | crew does with respect to the image | video displayed for passengers. Only operation was possible. Normally, when a dual view display is used as a monitor of a navigation device, a navigation image is displayed on the driver's seat side, and a television image, a DVD (Digital Versatile Disk) image, or the like is displayed on the passenger seat side. In this case, there is a problem that the passenger can only operate the TV image and the like, but cannot operate the navigation image.

  The present invention has been made to solve such a problem, and an object of the present invention is to enable passengers to perform operations on in-vehicle electronic devices while traveling without performing troublesome operations.

In order to solve the above-described problems, in the present invention, it is detected that the driver has performed a touch operation on the first image displayed in the direction of the driver's seat on the dual view display , and the assistant When it is detected that a passenger is seated in the seat, an operation menu screen for the first video is displayed in the direction of the passenger seat.

In another aspect of the present invention, when the driver performs an operation on the first image when the vehicle is stopped, the vehicle starts traveling , and the passenger is seated in the passenger seat. Displays the latest operation menu screen displayed in the direction of the driver's seat immediately before the start of traveling in the direction of the passenger seat.

  According to the present invention configured as described above, the operation menu screen for the first video is displayed as the video for the passenger seat only by the driver touching the screen while the vehicle is traveling. This makes it possible for the passenger in the passenger seat to perform operations on the first image while the vehicle is traveling, without performing troublesome operations such as changing the vehicle.

  Further, according to another feature of the present invention, when a desired operation started by the driver while the vehicle is stopped cannot be completed to the end, and driving must be started in the middle of the operation However, since the operation menu screen displayed immediately before the start of traveling is displayed as the image for the passenger seat, the passenger in the passenger seat can take over the operation performed halfway by the driver.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of the in-vehicle electronic device according to the present embodiment. The on-vehicle electronic device shown in FIG. 1 shows an audio integrated car navigation device 10 having, for example, a navigation function and an AV (Audio Visual) playback function as an example.

  As shown in FIG. 1, an audio integrated car navigation device 10 according to this embodiment includes a navigation control unit 11, a DVD control unit 12, a TV control unit 13, a video selection unit 14, a display controller 15, a display device (dual view display). ) 16, a controller 17, a vehicle speed sensor 18, and a motion sensor 19.

  The navigation control unit 11 detects the current position of the vehicle using a self-contained navigation sensor, a GPS receiver, etc., and performs driving guidance by reading out map data in the vicinity of the vehicle position from a recording medium and displaying it on the screen. It is. The navigation control unit 11 outputs map image data.

  The DVD control unit 12 reproduces and outputs image data recorded on a DVD. DVD image data is output from the DVD control unit 12. The TV control unit 13 receives and processes TV broadcast radio waves. Television image data is output from the TV control unit 13.

  The video selection unit 14 inputs map image data output from the navigation control unit 11, DVD image data output from the DVD control unit 12, and television image data output from the TV control unit 13. Or one or two are selectively output. The display controller 15 causes the dual view display 16 to display video by outputting image data necessary for display to the dual view display 16 based on the image data output from the video selection unit 14.

  The dual view display 16 includes a display panel 16a and a touch panel 16b (corresponding to the touch detection unit of the present invention). The display panel 16a displays video based on image data, and is configured as shown in FIG. 2, for example, and can perform dual view display of video.

  As shown in FIG. 2, the display panel 16 a is configured by, for example, a combination of a switch liquid crystal 101 and a TFT (Thin Film Transistor) liquid crystal 102. The switch liquid crystal 101 is provided with a plurality of optical parallax barriers 103 at equal intervals. The parallax barrier 103 controls the traveling direction of light (liquid crystal backlight) and separates the light so that different lights reach the left and right observation positions 106 and 107. Further, in the TFT liquid crystal 102, the left image and the right image are alternately displayed on the left pixel group 104 and the right pixel group 105 which are alternately arranged.

  Light that passes through the parallax barrier 103 and passes through the left pixel group 104 reaches the left observation position 106, and light that passes through the parallax barrier 103 and passes through the right pixel group 105 reaches the right observation position 107. Thereby, on the display screen of one TFT liquid crystal 102, different images can be seen depending on the viewing direction. That is, the image seen from the driver's seat and the image seen from the passenger seat can be made different.

  For example, when the right seat is the driver's seat, the video selection unit 14 selects map image data and DVD image data, outputs the DVD image data to the left pixel group 104, and maps the map image data to the right pixel group 105. To display a navigation image (corresponding to the first image of the present invention) on the driver's seat side and a DVD image (corresponding to the second image of the present invention) on the passenger seat side. Is possible.

  The video selection unit 14 selects any one image data and outputs it to the left pixel group 104 and the right pixel group 105, so that the same video can be viewed from both the driver's seat and the passenger seat. It is also possible to make it possible.

  The touch panel 16b is superimposed on the front surface of the display panel 16a and detects a touch operation by the user. Here, in order to detect whether or not the user touches the touch panel 16a, for example, a resistance film method or an infrared method is used. The touch panel 16b detects the touch position of the user on the panel and outputs the coordinate data.

  The controller 17 controls the entire audio integrated car navigation device 10. The controller 17 is configured by a microcomputer including a CPU, a ROM, and a RAM, for example. Various programs for controlling the audio-integrated car navigation device 10 are stored in the ROM. The CPU executes various controls while using the RAM as a work memory in accordance with various programs stored in the ROM. In the present embodiment, in particular, processing relating to provision of an operation menu screen for the dual view display 16 is performed. Detailed processing contents regarding this menu provision will be described later.

  The navigation control unit 11 described above includes an autonomous navigation sensor and a GPS receiver in order to detect the current position of the vehicle. The autonomous navigation sensor includes a vehicle speed sensor 18 that outputs a single pulse for each predetermined travel distance to detect the travel distance of the vehicle, and an angular velocity sensor (not shown) such as a vibration gyro that detects the rotation angle of the vehicle. Including. The autonomous navigation sensor detects the relative position and direction of the vehicle using these vehicle speed sensor 18 and angular velocity sensor.

  In the present embodiment, the vehicle speed sensor 18 is used as a sensor (corresponding to the travel detection unit of the present invention) for detecting whether or not the vehicle is traveling. For example, the controller 17 determines that the vehicle is running when a pulse is output from the vehicle speed sensor 18, and determines that the vehicle is stopped when the pulse is not output. Further, it is determined that the vehicle has started running when a pulse starts to be output from a state in which no pulse is output.

  The motion sensor 19 detects whether the operator of the touch operation on the touch panel 16b is a driver or a passenger, and corresponds to the operator detection unit of the present invention. The motion sensor 19 detects the three-dimensional movement of the operator and can be realized by various means. For example, by irradiating infrared rays in the vicinity of the touch panel 16b and detecting changes in the infrared rays that occur when the operator's hand moves within the infrared irradiation area, it is possible to detect from either the driver side or the passenger side. It is possible to detect whether the operator is a driver or a passenger by checking whether the operator's hand has entered the infrared irradiation area.

  Although an example using infrared rays has been described here, visible light, ultrasonic waves, or the like may be used. In addition, it is possible to determine the operator by installing a camera, photographing the vicinity of the touch panel 16b, and recognizing the photographed image data.

  Alternatively, the menu for the driver's seat and the menu for the passenger's seat may be displayed at different positions in the screen, and which menu is operated is determined based on the coordinate data of the touch position. In this way, it is possible to identify whether the person who touched the touch panel 16b is a driver or a passenger without using the motion sensor 19.

  When the controller 17 detects that the vehicle is running based on the output from the vehicle speed sensor 18, and the motion sensor 19 detects that the touch operation on the touch panel 16b is performed by the driver. In addition, each unit is controlled to display an operation menu screen for the first video in the direction of the passenger seat.

  For example, as shown in FIG. 3A, while the vehicle is running, a navigation video is displayed as the first video on the driver's seat side, and a DVD video is displayed as the second video on the passenger seat side. To do. When the driver performs a touch operation on the touch panel 16b in such a state, as shown in FIG. 3B, the passenger seat image is switched from the previous DVD image to the navigation image, and the navigation image is displayed. The operation menu screen for video is displayed. At this time, the video for the driver's seat remains the navigation video, but a message indicating that the operation while traveling is prohibited is displayed.

  In the state of FIG. 3A, the controller 17 causes the video selection unit 14 to select normal navigation image data output from the navigation control unit 11 and DVD image data output from the DVD control unit 12. I have control. Then, the display controller 15 is controlled so that the first video based on the navigation image data is displayed on the driver's seat side and the second video based on the DVD image data is displayed on the passenger seat side.

  On the other hand, in the state of FIG. 3B, the controller 17 stops selecting the DVD image data output from the DVD control unit 12 and only the navigation image data output from the navigation control unit 11 is obtained. The video selection unit 14 is controlled to select. At the same time, the controller 17 controls the navigation control unit 11 so that the navigation control unit 11 outputs navigation image data including a menu operation screen and navigation image data including a warning message. Then, the display controller 15 is controlled so that an image based on the navigation image data including the warning message is displayed on the driver's seat side, and an image based on the navigation image data including the menu operation screen is displayed on the passenger seat side.

  Next, the operation of the audio integrated car navigation apparatus 10 configured as described above will be described. FIG. 4 is a flowchart showing an operation example of the audio-integrated car navigation device 10 according to the present embodiment. Here, as shown in FIG. 3A, a description will be given assuming that a navigation video is displayed in the driver seat direction and a DVD video is displayed in the passenger seat direction.

  First, the controller 17 determines whether or not a touch operation on the touch panel 16b has been performed according to the presence or absence of data output from the touch panel 16b (step S1). Here, when a touch operation is not detected, the process of step S1 is repeated. On the other hand, when a touch operation is detected, the controller 17 determines whether the operator is a driver or a passenger based on the output from the motion sensor 19 (step S2).

  Here, when the operator is not a driver, that is, when it is detected that the operator is a passenger, it is possible to return to the process of step S1 and continue the menu operation regarding the DVD video. On the other hand, when it is detected that the operator is a driver, the controller 17 determines whether or not the vehicle is traveling according to the presence or absence of an output from the vehicle speed sensor 18 (step S3). Here, if it is detected that the vehicle is not running, the process returns to step S1.

  On the other hand, when it is detected that the vehicle is traveling, the controller 17 displays an operation menu screen for the navigation image in the direction of the passenger seat as shown in FIG. The navigation control unit 11, the DVD control unit 12, the video selection unit 14, and the display controller 15 are controlled so as to display a warning message indicating that the operation is prohibited in the direction of the driver's seat (step S4). In response to this, the passenger in the passenger seat performs an operation according to the displayed operation menu screen. When a series of operations is completed, the navigation control unit 11 executes a process according to the operation, and a navigation video reflecting the processing result is displayed on the driver's seat side. At this time, the image on the passenger seat side returns to the original DVD image.

  Note that the processing procedures of steps S1 to S3 described above are merely examples, and are not necessarily in this order. As long as the process of step S2 is after the process of step S1, it may be performed in any order.

  As described above in detail, in the present embodiment, when it is detected that the driver performs a touch operation on the navigation image displayed in the direction of the driver's seat on the dual view display 16, the navigation image is displayed. Is displayed in the direction of the passenger seat. As a result, the operation menu screen for the navigation image is displayed for the passenger seat only by the driver touching the touch panel 16b while the vehicle is running, so that without performing troublesome operations such as changing the direction of the display, A passenger in the passenger seat can operate the navigation image while the vehicle is running.

  In the above-described embodiment, the case where the dual view display of the navigation video and the DVD video is performed is described as an example, but this is merely an example. The dual view display of the navigation video and the TV video may be performed, or the dual view display of the DVD video and the TV video may be performed. Also, the present embodiment can be applied when dual view display based on one video source is performed.

  Moreover, although the said embodiment demonstrated the process when a driver | operator performed touch operation during driving | running | working of a vehicle, it is not limited to this. Since it is possible for a driver to operate while the vehicle is stopped, the driver may start a desired operation when the vehicle is stopped waiting for a signal, for example. However, the desired operation does not always finish until the signal turns blue. In particular, when the menu has a hierarchical structure, traveling may be forced to start during the operation.

  In such a case, when the controller 17 detects the start of traveling of the vehicle based on the output from the vehicle speed sensor 18, the most recent operation menu screen displayed as a driver seat image at that time is displayed in the direction of the passenger seat. May be displayed. This can be realized by the controller 17 controlling the display controller 15 to switch the output destination of the navigation video including the operation menu screen from the driver seat side to the passenger seat side.

  In the above embodiment, the navigation video operation menu screen is always displayed in the direction of the passenger seat when the driver performs a touch operation while the vehicle is traveling, but the passenger in the passenger seat is the navigation system. There is a case where the user is not well aware of and the operation is unguided. In order to cope with such a case, when the navigation video operation menu screen is displayed in the direction of the passenger seat as shown in FIG. 5, a rejection operation item such as the return button 51 indicated as “return” is also displayed. It may be displayed so that the passenger in the passenger seat can reject the operation by touching it.

  In this case, when the controller 17 detects a touch operation on the return button 51 based on the coordinate data output from the touch panel 16b, the controller 17 displays the navigation video operation menu screen again in the driver seat direction. However, since the driver's operation is prohibited while the vehicle is traveling, the navigation video operation menu screen is displayed again in the direction of the driver's seat when the vehicle speed sensor 18 detects again that the vehicle is not traveling. Is preferred.

  In addition, as described above, when the operation started while the vehicle is stopped can be continuously operated on the passenger seat side after the start of traveling, the menu operation screen including the return button 51 is displayed in the passenger seat direction. It is also possible to allow the passenger in the passenger seat to refuse the operation. In this case, when the stop of the vehicle is detected again, it is preferable to redisplay the latest operation menu screen in the direction of the driver's seat when the driver originally operated before the start of traveling. A configuration example for realizing this is shown in FIG.

  FIG. 6 is a block diagram illustrating another configuration example of the in-vehicle electronic device according to the present embodiment. Also here, an audio integrated car navigation device 20 is shown as an example of the in-vehicle electronic device. In FIG. 6, components having the same reference numerals as those shown in FIG. 1 have the same functions, and thus redundant description is omitted here.

  The audio integrated car navigation device 20 shown in FIG. 6 includes an operation information storage unit 21 and a memory 22 in addition to the configuration shown in FIG. The operation information storage unit 21 stores the most recent operation menu screen as operation information when displaying the above-described most recent operation menu screen in the passenger seat direction. A history of operations performed by the driver while the vehicle is stopped may be stored in the memory 22 and stored.

  In the latter case, the operation information storage unit 21 detects that the vehicle is not running by the vehicle speed sensor 18 and the controller 17 detects that the touch operation is performed by the driver by the motion sensor 19. The operation menu screen displayed by the touch operation and the operation item selected in the operation menu screen are stored in the memory 22 as operation information.

  Further, in the example of FIG. 6, the controller 17 displays a navigation video menu operation screen including the return button 51 as shown in FIG. 5 in the direction of the passenger seat when the vehicle speed sensor 18 detects the start of traveling of the vehicle. Control each part. Further, the controller 17 detects whether or not the return button 51 has been touched, and if touched, when the vehicle speed sensor 18 subsequently detects again that the vehicle is not traveling (the vehicle has stopped again). ), Based on the operation information stored in the memory 22 by the operation information storage unit 21, control is performed so that the latest operation menu screen that was displayed when the previous run was started is displayed again in the direction of the driver's seat.

  In the above embodiment, the navigation video operation menu screen is always displayed in the direction of the passenger seat when the driver performs a touch operation while the vehicle is traveling. However, the passenger is seated in the passenger seat. Only in this case, the operation menu screen may be displayed in the direction of the passenger seat. A configuration example in this case is shown in FIG.

  FIG. 7 is a block diagram showing still another configuration example of the in-vehicle electronic device according to the present embodiment. Also here, an audio integrated car navigation device 30 is shown as an example of the in-vehicle electronic device. In FIG. 7, those given the same reference numerals as those shown in FIG. 1 have the same functions, and therefore redundant description is omitted here.

  In addition to the structure shown in FIG. 1, a seating detection sensor 23 is connected to the audio integrated car navigation device 30 shown in FIG. The seating detection sensor 23 detects whether or not a passenger is seated in the passenger seat. In the example shown in FIG. 7, the controller 17 performs control so that the operation menu screen for the first video is displayed in the direction of the passenger seat only when the passenger detection is detected by the seating detection sensor 23.

  The seating detection sensor 23 can be constituted by, for example, a pressure sensor or a weight sensor installed in the passenger seat. It is also possible to determine the presence or absence of a passenger in the passenger seat by installing a camera, photographing the vicinity of the passenger seat, and recognizing the captured image data. Alternatively, the presence or absence of a passenger may be determined by irradiating an infrared ray in the vicinity of the passenger seat and detecting a change in the reflected wave of the infrared ray in the vicinity of the passenger seat.

  Even when the operation menu screen is displayed in the passenger seat direction only when the passenger is seated in the passenger seat, the menu operation screen including the return button 51 described above is displayed in the passenger seat direction. Thus, the passenger in the passenger seat may be allowed to refuse the operation.

  When there is no passenger, the driver must perform the operation on the navigation image, but the operation while traveling is prohibited. However, since the operation can be performed while the vehicle is stopped, a desired operation can be performed when the vehicle is stopped waiting for a signal, for example. However, when the signal changes to blue during the operation and the vehicle has to start running, the desired operation may not be completed. In this case, when the vehicle stops again, it is preferable that the operation can be continued again from the latest operation menu screen displayed before the start of traveling.

  A configuration example for realizing this is shown in FIG. FIG. 8 is a block diagram showing still another configuration example of the in-vehicle electronic device according to the present embodiment. Also here, an audio integrated car navigation device 40 is shown as an example of the in-vehicle electronic device. In FIG. 8, components having the same reference numerals as those shown in FIGS. 6 and 7 have the same functions, and thus redundant description is omitted here.

  In the example shown in FIG. 8, the operation information storage unit 21 is, for example, when the vehicle speed sensor 18 detects the start of traveling of the vehicle and the seating detection sensor 23 detects that the passenger is not seated. In accordance with the control from the controller 17, the latest operation menu screen displayed in the direction of the driver's seat immediately before the start of traveling is stored in the memory 22 as operation information.

  At this time, the controller 17 controls each part so as not to accept the operation by the driver by erasing the operation menu screen that has been displayed in the direction of the driver's seat until then. Thereafter, when it is detected again by the vehicle speed sensor 18 that the vehicle is not traveling (when the vehicle stops again), when traveling is started based on the operation information stored in the memory 22 by the operation information storage unit 21. Control is performed so that the most recent operation menu screen displayed in is displayed again in the direction of the driver's seat.

  Moreover, in the said embodiment, although what used the parallax barrier as shown in FIG. 2 was mentioned as an example as a technique which implement | achieves the dual view display 16, it is not limited to this. For example, a lens using a lenticular lens may be used.

  In the above embodiment, the navigation control unit 11 generates and outputs navigation image data including a menu operation screen as shown in FIG. 3B and navigation image data including a warning message. It is not limited to this. For example, a menu operation screen and a menu generation unit for generating a warning message are provided separately, and the navigation control unit 11 generates and outputs a normal navigation image. Then, the navigation image output from the navigation control unit 11 and the menu operation screen or warning message output from the menu generation unit may be combined and output.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
