Description

  In the present invention, for example, a plurality of vehicles for a front monitor and a rear monitor are mounted on a vehicle, and the moving image display on the rear monitor can be controlled even when the moving image cannot be displayed on the front monitor when the vehicle is running. The present invention relates to a monitor control device and a control method.

  In recent years, navigation devices have been widely installed in vehicles, and vehicles are equipped with a monitor that displays a map screen or the like. In many devices, a television reception image can be displayed on the monitor. Yes. Furthermore, with the recent spread of DVD players, a DVD (Digital Versatile Disk) player is often connected to the monitor to watch a television or a DVD.

  In addition, due to the recent increase in capacity and price of hard disks (HDD), HDDs are used as data recording media for navigation devices, and portable HDDs are also used. A small hard disk is also used as an audio recording medium. Furthermore, AV (Audio Visual) devices equipped with HDDs and DVDs have become widespread for general households, and various types of video are recorded on the HDDs. You can watch videos and music. In particular, the interior space where the vehicle is closed and has little influence on the outside and sufficient sound effects are obtained is a perfect audiovisual viewing space.

  On the other hand, when viewing images on a TV, DVD, or HDD mounted on a vehicle with a monitor, if the driver is in a state where it can be used like a monitor of a normal navigation device, it is safe driving. The viewing of these images is restricted when the vehicle is running by detecting the operation of the vehicle speed sensor and parking brake so as not to affect the vehicle.

  In addition, with the recent spread of these AV devices, a monitor other than the driver's seat monitor is mounted on the rear seat or the passenger seat in the vehicle, and the images of the various AV devices as described above are also viewed on these monitors. Things are also happening. Especially in high-end vehicles, the owner of the vehicle often sits in the rear seat. Therefore, in addition to the front monitor that mainly uses the navigation device placed around the driver's seat, a rear monitor as the main monitor is placed in the rear seat. Will be.

  Also, in the passenger seat, the conventional map guidance by the passenger in the passenger seat has become unnecessary due to the installation of the navigation device, and the passenger seat is often loaded with passengers in the passenger seat. An auxiliary monitor may be arranged for this purpose. Furthermore, in recent years, a large family, such as a three-row seat for eight passengers, has also become widespread. ) It is also increasingly used as a device.

  However, since the front monitor arranged in front of the driver's field of view in order to use the navigation device is restricted from viewing various AV devices while the vehicle is running, By simply outputting the video output of the AV device to be output to another monitor such as a rear monitor other than the front monitor, the rear monitor or the like cannot be viewed on the rear monitor or the like while the vehicle is running. Therefore, it can be said that it is important for other passengers other than the driver to be able to receive TV and reproduce / view DVDs and HDDs during a monotonous time while the vehicle is running.

  For this purpose, a second AV device for outputting to another monitor such as a rear seat is installed separately from the AV device outputting to the front monitor so that it can be operated independently. It is done. However, it is expensive and often wasteful to install a plurality of AV devices performing the same function in one vehicle.

As a countermeasure, Patent Document 1 discloses that the video and audio can be output to other monitors independently from the video and audio output from the front monitor. Even when TV or DVD video output is not performed, the output is output to other monitors so that other passengers other than the driver can view and enjoy with one AV device. Has been proposed.

  As described above, when, for example, a rear monitor is arranged in addition to the front monitor of the vehicle, the rear monitor side can also output a video from an AV device such as a TV or a DVD or HDD while the vehicle is running. Since it is extremely inconvenient that those videos are not output and cannot be viewed, such video and audio are output to other monitors independently of the video and audio output from the front monitor as in the above conventional technology. It is preferable to be able to do so.

  However, when the rear seat as described above is arranged in the rear seat and the rear seat occupant receives the TV while the vehicle is running or plays a DVD, HDD or the like and views it, board the rear seat of the vehicle. If the person is a child unfamiliar with the operation of these devices, for example, when the child is watching a music video DVD, or if the screen is interrupted due to the end of chapter playback, etc. Even if the father and mother are driving, they may start to make a noise saying "Show me the next!" In such a case, the vehicle must be parked nearby and operated by the operation unit on the front side to reproduce the next video.

  Thus, it is inconvenient for passengers to be unable to perform AV device viewing operations on the rear monitor or the like of the rear seat while the vehicle is running, and the driver is particularly frustrated. Therefore, it is preferable that the AV device that is viewed on the rear monitor or the like can be easily operated while the vehicle is running.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram showing functional units for implementing the present invention and their interrelationships. In addition, the function part which performs various functions in the figure can also be said to be a means which performs various functions, respectively. In the example shown in FIG. 1, the front monitor 1 disposed in front of the driver's field of view is controlled by the front monitor controller 2, and the user operates the front monitor operation instruction unit 6 such as a remote control or a touch panel. Thus, a desired image is displayed.

  The illustrated front monitor control unit 2 shows an example in which a navigation device 8, a TV receiver 9, and a DVD player 10 that are mounted on the vehicle or connected by a user are connected. An HDD drive, a video tape recorder, etc. can be arbitrarily connected according to the situation. Any of these devices can be operated by an output device selection unit 3 that operates in response to a user's selection instruction input, and an image of the device can be output to the front monitor 1.

  The front monitor control unit 2 inputs a signal from the vehicle stop detection unit 7 and inputs an operation detection signal of a vehicle speed sensor or a parking brake to detect whether or not the vehicle is currently stopped. When such a signal indicating that the vehicle is stopped is received from the vehicle stop detection unit 7, the front monitor control unit 2 operates such as the television receiver 9, the DVD player 10, etc. other than the navigation device 8. If so, control is performed to stop at least the output of the moving image. When the output of the moving image is stopped, various substantial still images can be output under the preset conditions in addition to the image of the navigation device.

  In this vehicle, a rear monitor 11 is provided for a passenger in the rear seat of the vehicle and can be controlled by the rear monitor control unit 12. In the illustrated example, the device output to the rear monitor 11 is a device. The rear monitor operation instruction unit 13 is provided so that a person on the rear seat can operate independently. In the embodiment shown in FIG. 1, the rear monitor 11 is shown as a monitor other than the front monitor 1, but the “other monitor” other than the front monitor 1 is installed in the passenger seat. The same can be applied to an auxiliary monitor or the like. In the illustrated example, signals from the TV receiver 9 and the DVD player 10 are input to the rear monitor control unit 12 so that the rear monitor control unit 12 can control the signals independently from the front monitor control unit 2. ing. The rear monitor control unit 12 may input a signal of the navigation device 8 as necessary. When the HDD or the like is mounted as described above, these reproduced images are input, and the operation is rearranged. To be able to do from.

  In the multiple monitor control device composed of the functional blocks as described above, for example, it can be operated in order according to the operation flow shown in FIG. The operation will be described below with reference to the functional block diagram of FIG. 1 and the monitor display example of FIG. In the example shown in FIG. 2, an example in which a playback video of a DVD is particularly displayed on the rear monitor is shown, but the present invention can be similarly applied to playback of other AV devices. In the rear monitor reproduction display operation process from the front monitor side shown in FIG. 2, it is first determined whether or not the vehicle is stopped (step S1). This determination is made by the front monitor control unit 2 in FIG. 1 receiving a vehicle stop detection signal from the vehicle stop detection unit 7 by a vehicle speed sensor or a parking brake signal.

  As a result, when it is determined that the vehicle is stopped, it is possible to output images of all devices desired by the user to the front monitor 1 (step S7), and the same operation is repeated by returning to step S1. In such a case, for example, as shown in FIG. 3A, a playback image of a DVD can be displayed on both the front monitor and the rear monitor. These operations are performed when the front monitor control unit 2 controls the front monitor 1 of FIG. 1 and the rear monitor control unit 12 controls the rear monitor 11, for example, the rear monitor side and the front monitor side When displaying the output of the same AV device, it is preferable to set various priority operations in advance, such as enabling only the operation of the front monitor control unit.

  If it is determined in step S1 that the vehicle is not stopped, it is determined whether or not there is a request for displaying a DVD menu screen for the rear monitor on the front monitor (step S2). If it is determined that there is a request for displaying the DVD menu screen for the rear monitor on the front monitor, the DVD menu screen for the rear monitor is displayed on the front monitor in this embodiment in step S3. If it is determined that there is no such display request, the process returns to step S1 and the above operation is repeated.

  That is, the front monitor displays a map image or the like of the navigation device as shown in FIG. 3 (b) in many cases while the vehicle is running, but when a DVD playback image is separately displayed on the rear monitor. Then, the front monitor is set to display the DVD menu screen by performing playback on the rear monitor. In the setting, the navigation screen is displayed in principle while the vehicle is running, and when necessary, the user touches a predetermined part of the screen or operates a specific switch as described above. In step S3, when these setting conditions are satisfied, it is determined that the front monitor has a request to display the DVD menu screen for the rear monitor.

  In this operation, the rear monitor operation menu screen display unit 5 in FIG. 1 displays a menu on the front monitor 1 by detecting software instructions set in advance or a user instruction to the front monitor operation instruction unit 6. Execute by. The menu display on the front monitor 1 can be realized by simultaneous buffering of the DVD main part and the menu screen, thereby enabling not only the display of the menu screen but also a direct operation from the menu screen. It is possible to perform an intuitive operation by displaying the menu.

  When the menu is displayed on the front monitor as described above, the screen of the front monitor may be divided into two so that one side is displayed as a navigation screen and the menu screen is displayed on the other side. Further, on the menu screen displayed on the front monitor, the playback portion currently displayed on the rear monitor may be highlighted on the menu screen.

  Such a screen display state is shown in FIGS. 3B and 3C. In FIG. 3B, the continuation of the DVD playback of FIG. 3A is reproduced on the rear monitor. On the other hand, the DVD reproduction image is not displayed on the front monitor by the traveling of the vehicle, and the normal navigation image is displayed. Also, in FIG. 3C, the DVD playback displayed on the rear monitor is stopped at the last part of the chapter, and at that time, the menu screen is displayed on the front monitor according to the user's instruction, etc. An example is shown in which the highlighted portion is highlighted.

  In such a state, it is determined whether or not a DVD playback selection instruction is given from the user on the front monitor side (step S4). As a result of the determination, the user on the front monitor side, for example, sees the menu screen in FIG. 3C and the highlighted portion thereof, and the video that has been reproduced and displayed on the rear monitor until now is “Youth declaration of Aya Matsuura”. Next, an instruction such as reproduction of the next “W (double-you)” is given. In this case, it is also possible to ask the child in the back seat, etc. who will listen to the next song, and arbitrarily select and play the artist's song.

  When such a rear DVD playback selection instruction is given, a rear DVD playback selection operation is executed in accordance with the playback selection operation instruction (step S5). In this operation, the user on the front monitor side looks at the menu screen displayed on the front monitor 1 of FIG. 1 or FIG. This can be performed by transmitting the signal to the rear monitor control unit 12 and executing the signal instead of the input of the rear monitor operation instruction unit. If it is determined in step S4 that there is no instruction to select DVD playback from the user on the front monitor, the process returns to step S1 and the above operation is repeated.

  After the rear monitor DVD playback selection operation is executed in the menu display on the front monitor in step S5, it is determined whether or not the display on the rear monitor has ended (step S6). If not, the process returns to step S1 again. Repeat the above operation. If it is determined in step S6 that the display on the rear monitor is finished, these processes are finished in step S9.

  The present invention is a vehicle for general families that allows a DVD operation to be easily performed from the front side when a DVD or the like is viewed while a vehicle is traveling while a child or the like is riding on the rear seat and the DVD operation is unknown. In addition to the above, when a VIP rides on the rear seat in a VIP vehicle, a variety of multiple monitors such as a VIP vehicle that can assist the operation of AV equipment output from the front monitor side to the rear monitor can be provided. Each vehicle can be used effectively in a specific manner.
