A display device that displays a passenger seat display image on the pixel 109 is disclosed. In this display device, by providing the light shielding bands 142 and 144, the light emitted from the right side (driver seat side) display pixel 110 that displays the driver seat display image is incident on the eyes of the driver 11. The light emitted from the left-side (passenger-seat) display pixel 109 that displays the passenger-seat display image is not incident on the eyes of the driver 11, while the left-hand side (assistant) that displays the passenger-seat display image. The light emitted from the display-side pixel 109 is incident on the passenger seat occupant 10, but the light emitted from the right-side (driver-side) display pixel 110 that displays the display image for the driver's seat is the assistant. The light is prevented from entering the seat occupant 10.

  By adopting such a display device for an in-vehicle display device, as shown in FIG. 13, a map display image 9 by the navigation device is displayed so that it can be seen from the driver 11 but not from the passenger 10. Then, the DVD display image 8 by the DVD player can be displayed so as to be visible from the passenger seat occupant 10 but not from the driver 11. As a result, even when the vehicle is traveling, the passenger seat occupant 10 can watch TV, movies, and the like.

  The present invention functions as the display device 20 and / or the remote control device in a situation where individual display images for different viewing directions (for example, different display images in two different directions) are displayed on the display device 20. The present invention relates to a control system that can be appropriately operated using a remote controller 217. Hereinafter, the control contents in the control system will be described in five embodiments. Note that displaying separate display images (for example, different display images in two different directions) for a plurality of viewing directions is referred to as “separate display”.

(First embodiment)
In the first embodiment, the remote controller 217 performs a driver seat operation mode (DR mode) in which a control operation is performed on the second image source 2 with respect to the second display image (driver seat display image) 9. A mode setting unit for determining which mode to select a passenger seat operation mode (PA mode) for performing a control operation on the first image source 1 for the display image (passenger seat display image) 8 is doing. By the way, mode setting determines which viewing direction of a plurality of viewing directions is to be indicated, and which of a plurality of image sources (navigation unit 206, DVD playback unit 204, etc.) is to be indicated. It also corresponds to.

  In addition, by setting the mode on the remote controller 217 by a method to be described later, either the corresponding operation switch for DR mode or the operation switch for PA mode is displayed on the remote control side display unit 53, and the remote control operation is performed. Using the touch panel included in the unit 54 and / or the remote-control-side display unit 53, it is configured to be able to perform an operation input for either the DR mode or the PA mode.

  Further, the remote control side control unit 52 of the remote control 217 corresponds to a mode setting signal indicating the mode setting status and an operation input input from the remote control side operation unit 54 of the remote control 217 or the touch panel provided on the remote control side display unit 53. Control signal generated. Next, the remote control side control unit 52 transmits the generated mode setting signal and control signal from the remote control side transmission / reception unit 55 to the remote control transmission / reception unit 216. The control unit 200 of the display device identifies the target image source based on the received mode setting signal, and controls the target image source based on the received control signal.

  That is, in the case of the first embodiment, the remote controller 217 has a mode setting function, and the display device 20 has a control function for controlling a target image source by a control signal.

  FIG. 14 is a flowchart for explaining the control contents in the first embodiment. This control is started by instructing separate display on the display device 20. Moreover, this flowchart is repeated until the separation display is canceled. First, in step a1, the control unit 52 of the remote controller 217 refers to the initial setting information and sets the operation mode of the remote controller 217. For example, when the DR mode is set as the initial mode, the remote control 217 sets the DR mode.

  In step a2, it is determined whether or not an operation has been performed on the remote controller 217. When the operation is performed, the operation content is determined (step a3). When the operation content is an operation other than the mode switching operation, a process corresponding to the operation is performed (step a4). For example, in the case of an operation in the DR mode, that is, an operation on the driver seat display image, the control unit 200 of the display device 20 performs corresponding operation control. Thereafter, the process returns to step a2.

  On the other hand, when the operation content is a mode switching operation, the operation mode is switched (step a5). For example, when a mode switching operation is performed when the DR mode is set, the remote controller 51 sets the PA mode. Thereafter, the process returns to step a2.

As the mode switching operation (mode setting operation), the following operations can be considered.
1) Press the changeover switch constituted by the display unit 53. In this case, the initial mode of the initial setting information is set to the DR mode or the PA mode, and the operation mode is switched with the fact that the changeover switch has been pressed as a mode switching command. The initial setting information is stored in a memory in the control unit 52. The initial setting information and the mode switching command correspond to the mode setting information, the changeover switch of the control unit 52 and the display unit 53 corresponds to the mode setting information output unit, and the control unit 52 corresponds to the operation mode control unit.

  2) A mechanical switch having two connection modes (configured as a part of the remote control side operation unit 54) is switched. In this case, the operation mode is switched based on the connection mode of the mechanical switch. For example, one connection mode is set to the DR mode and the other connection mode is set to the PA mode, and the operation mode is switched based on the connection mode of the mechanical switch. The initial mode is determined by the connection mode of the mechanical switch. The connection mode of the mechanical switch corresponds to mode setting information, the mechanical switch and control unit 52 corresponds to a mode setting information output unit, and the control unit 52 corresponds to an operation mode control unit.

  3) A detector (such as a gyroscope) for detecting the vibration amount is provided in the remote controller 51, and the operation mode is switched by shaking the remote controller 51. In this case, the initial mode of the initial setting information is set to the DR mode or the PA mode, and the operation mode is switched using a mode switching command that the amount of vibration detected by the detector exceeds the reference value. The initial setting information and the mode switching command correspond to mode setting information, the detector and control unit 52 corresponds to a mode setting information output unit, and the control unit 52 corresponds to an operation mode control unit.

  4) A memory for storing an input unit for inputting personal identification information for identifying an observer, a recognition unit for recognizing an observer based on the input personal identification information, and an operation mode set for the observer in association with each other. The operation mode stored in the storage unit is set in association with the recognized observer. In this case, the operation mode corresponding to the observer first recognized after the separation display is instructed is the initial mode. Thereafter, each time the observer is recognized, the operation mode is switched. The operation mode stored in the storage unit corresponds to mode setting information, the input unit, the recognition unit, and the storage unit correspond to a mode setting information output unit, and the control unit 52 corresponds to an operation mode control unit. To do.

  5) A direction detection device that detects the direction in which the remote controller 51 is present with respect to the display device 20 is provided, and the operation mode is switched according to the direction detected by the direction detection device. For example, when the direction in which the remote controller 51 exists is the driver's seat direction, the DR mode is set. Details of the direction detection will be described later (see the fifth embodiment). The detected direction corresponds to mode setting information, the direction detection device corresponds to a mode setting information output unit, and the control unit 52 corresponds to an operation mode control unit.

According to the first embodiment, the following effects can be obtained.
(1) In the above embodiment, the DR mode and the PA mode can be appropriately switched by the observer performing a predetermined mode switching operation. Therefore, each operation for the two display images displayed on the display device 20 can be appropriately performed from one remote controller 51.

  The first embodiment may be modified so as to determine the effective operation setting condition on the display device 20 side (a first modification of the first embodiment).

  The valid operation setting condition is, for example, that the operation to the first image source 1 corresponding to the first display image (passenger seat display image) 8 is validated, and the second display image (driver seat display). This is a condition for invalidating the operation on the second image source 2 corresponding to (image) 9. For example, if the effective operation setting condition is a condition that is satisfied when the driver is in a situation where he / she should concentrate on driving, when the driver should concentrate on driving (the control unit 200 of the display device 20 is effective) By determining whether or not the operation setting condition is satisfied and controlling the setting of the image source by the mode setting signal from the remote controller 217, an operation input to the second display image (driver seat display image) 9 is performed. It becomes invalid and cannot be operated by the remote controller 217. As a result, the driver is prevented from being distracted by the operation of the remote controller 217, and safety during vehicle traveling can be improved.

  That is, in the first modification of the first embodiment, the remote controller 217 has a mode setting function, the display device 20 has a control function for controlling a target image source by a control signal, and the display device 20 is effective. It is determined whether or not the operation setting condition is satisfied, and the mode setting is controlled based on the condition determination.

  FIG. 15 is a flowchart for explaining the contents of control performed when the valid operation setting condition is satisfied. This control is started by instructing separate display on the display device 20. Moreover, this flowchart is repeated until the separation display is canceled. First, in step a11, the control unit 52 of the remote controller 217 refers to the initial setting information and sets the operation mode of the remote controller 217. For example, when the DR mode is set as the initial mode, the remote control 217 sets the DR mode.

  In step a12, it is determined in the control unit 200 of the display device 20 whether or not an effective operation setting condition is satisfied. If the condition is satisfied, in step a13, only the operation in the PA mode is enabled and the operation in the DR mode is disabled. On the other hand, if the condition is not satisfied, the operation in both the PA mode and the DR mode is validated in step a14.

  The following control method can be considered as the control (mode setting) in step a13. During the period when the valid operation setting condition is satisfied, control corresponding to the operation is not performed even if the operation in the DR mode is performed. This can be realized by preventing the control unit 200 that has received the operation signal from the remote controller 217 from performing the corresponding control.

  In step a15, it is determined whether or not the operation mode set by the remote controller 217 in the control unit 200 is a valid mode. The effective mode is a mode in which an operation in that mode is valid. If the mode is the valid mode, that is, the PA mode, the process proceeds to step a16. If the mode is not the valid mode (the invalid mode), that is, if the mode is the DR mode, the process proceeds to step a19.

  In step a16, it is determined whether or not the control unit 200 has operated the remote controller 217. When other operations other than the mode switching operation are performed, a process corresponding to the operation is performed (step a17). In this case, since the operation in the PA mode, that is, the operation on the passenger seat display image is performed, the control unit 200 of the display device 20 performs the corresponding operation control. Thereafter, the process returns to step a12.

  On the other hand, when the mode switching operation is performed, the operation mode is switched in the control unit 52 (step a18). Here, since the PA mode is set, the operation mode is switched to the DR mode. Thereafter, the process returns to step a12.

  If it is determined in step a15 that the DR mode is set, it is determined in step a19 whether or not a mode switching operation has been performed on the remote controller 217. When the mode switching operation is performed, the operation mode is switched (step a18). Since the DR mode is set here, the operation mode is switched to the PA mode. That is, even when the valid setting condition is set, the mode can be switched even when the valid setting condition is satisfied in the state where the DR mode is set so that the operation in the PA mode can be performed. Thereafter, the process returns to step a12. If any operation other than the mode switching operation is performed on the remote controller 217, the process returns to step a12 without performing processing corresponding to the operation.

  When the driver is in a situation where he should concentrate on driving, when the vehicle is driving, at night, driving on a highway, driving on a complicated road such as a lot of curves And so on.

  The fact that the vehicle is traveling is, for example, that the speed of the vehicle detected by the vehicle speed sensor is 5 km / h or more, that the parking brake signal (PKB signal) is OFF, and that the GPS from the GPS information receiving unit 213 (Global positioning system) It can be determined based on the detection of the movement of the vehicle by the signal, the detection of vibration based on the detection result of the gyroscope built in the navigation unit 206, and the like.

  The fact that it is nighttime, for example, that the observer has instructed the display device 20 to turn on illumination for nighttime, and that the current time obtained by the clock function is included in the time zone corresponding to nighttime. It can be determined based on the above.

  It can be determined, for example, based on the map information in the navigation unit 206 and the current position of the vehicle that the vehicle is traveling on a highway and a complicated road such as many curves.

  In the first modified example, the display device 20 performs the condition determination as to whether or not the effective operation setting condition is satisfied and the mode setting control based on the condition determination. However, in order to reduce the load on the control unit 200 of the display device 20, the condition determination as to whether or not the effective operation setting condition is satisfied and the mode setting control based on the condition determination are performed. You may be made to do. In that case, it is necessary for the remote controller 217 to receive information (for example, speed information from the vehicle speed sensor, PKB signal, GPS signal, etc.) for determining whether or not the valid operation setting condition is satisfied from the display device 20. There is.

  The first embodiment may be further modified so as to determine the priority operation setting operation condition on the display device 20 side (second modification of the first embodiment).

  The priority operation setting condition is, for example, an operation on the second image source 2 corresponding to the second display image (display image for driver's seat) 9, the first display image (display image for the passenger seat). 8 is a condition for giving priority to an operation on the first image source 1 corresponding to 8. For example, if the priority operation setting condition is a condition that is satisfied when the driver is in a situation where he / she should concentrate on driving, when the driver should concentrate on driving (the control unit 200 of the display device 20 is effective) By determining whether or not the operation setting condition is satisfied and controlling the setting of the image source by the mode setting signal from the remote controller 217, the operation input to the second display image (driver seat display image) 9 is performed. It cannot be done easily. As a result, the driver is prevented from being distracted by the operation of the remote controller 217, and safety during vehicle traveling can be improved.

  If an operation input to the second display image (driver seat display image) 9 is required, an instruction to cancel the invalidation indicates that the second display image (driver seat display image) 9 has an operation input. Is also effective. Accordingly, in the priority condition determination, the operation input for the second display image (driver seat display image) 9 is always invalidated (validity condition determination: first modification of the first embodiment). Compared to the above, the operability can be improved. The specific conditions for satisfying the valid operation setting conditions are the same as the valid operation setting conditions.

  That is, in the second modification of the first embodiment, the remote controller 217 has a mode setting function, the display device 20 has a control function of controlling the target image source by a control signal, and the display device 20 has priority. It is determined whether or not the operation setting condition is satisfied, and the mode setting is controlled based on the condition determination.

  FIG. 16 is a flowchart for explaining the control content performed when the priority operation setting condition is satisfied. This control is started by instructing separate display on the display device 20. Moreover, this flowchart is repeated until the separation display is canceled. First, in step a21, the control unit 52 of the remote controller 217 refers to the initial setting information and sets the operation mode of the remote controller 217. For example, when the DR mode is set as the initial mode, the remote control 217 sets the DR mode.

  In step a22, the control unit 200 determines whether or not a priority operation setting condition is satisfied. If the condition is satisfied, in step a23, only the operation in the PA mode is enabled and the operation in the DR mode is disabled. On the other hand, if the condition is not satisfied, the operation in both the PA mode and the DR mode is validated in step a24.

  As the control in step a23, the following control method can be considered. During the period in which the priority operation setting condition is satisfied, control corresponding to the operation is not performed even if the operation in the DR mode is performed. This can be realized by preventing the control unit 200 that has received the operation signal from the remote controller 217 from performing the corresponding control.

  In step a25, it is determined whether or not the operation mode set by the remote controller 217 in the control unit 200 is a valid mode. The effective mode is a mode in which an operation in that mode is valid. If the mode is the valid mode, that is, the PA mode, the process proceeds to step a26. If the mode is not the valid mode (the invalid mode), that is, if the mode is the DR mode, the process proceeds to step a29.

  In step a26, it is determined whether or not the control unit 200 has operated the remote controller 217. When other operations other than the mode switching operation are performed, a process corresponding to the operation is performed (step a27). In this case, since the operation in the PA mode, that is, the operation on the passenger seat display image is performed, the control unit 200 of the display device 20 performs the corresponding operation control. Thereafter, the process returns to step a22.

  On the other hand, when the mode switching operation is performed, the control unit 52 switches the operation mode (step a28). Here, since the PA mode is set, the operation mode is switched to the DR mode. Thereafter, the process returns to step a22.

  If it is determined in step a25 that the DR mode is set, it is determined in step a29 whether or not a mode switching operation has been performed on the remote controller 217. When the mode switching operation is performed, the operation mode is switched (step a28). Since the DR mode is set here, the operation mode is switched to the PA mode. Thereafter, the process returns to step a22.

  Further, when an operation other than the mode switching operation is performed in step a29, it is determined in step a30 whether or not an invalidity canceling operation has been performed on the remote controller 217. When the invalidation canceling operation is performed, the operation in the DR mode is validated in step a31. Thereafter, in step a32, it is determined whether or not an operation on the remote controller 217 has been performed. When an operation is performed, the control unit 200 of the display device 20 performs operation control corresponding to the operation.

  After the process is completed, in step a34, it is determined whether or not a predetermined time has elapsed since the operation in the DR mode was performed. If the predetermined time has not elapsed, the process returns to step a32. On the other hand, if the predetermined time has elapsed, the operation in the DR mode is invalidated in step a35, and the process returns to step a22. Also, when a predetermined time has elapsed without performing the operation in the DR mode after the invalidation canceling operation is performed (steps a30, a31, a32, and a34), the operation in the DR mode is invalidated in step a35, and the process proceeds to step a22. Return.

  If it is determined in step a30 that the remote controller 217 has performed another operation other than the invalidation canceling operation, the process returns to step a22 without performing processing corresponding to the operation.

  As described above, when the priority operation setting condition is satisfied and the operation in the DR mode is originally invalidated, when the invalidation is canceled according to the instruction of the observer, the operation in the DR mode is performed again after a predetermined time elapses. Since it is invalidated, it is possible to limit the operation in the DR mode, and it is possible to improve the safety when the vehicle travels.

  In the second modified example, the display device 20 performs the condition determination as to whether or not the priority operation setting condition is satisfied and the mode setting control based on the condition determination. However, in order to reduce the load on the control unit 200 of the display device 20, whether the priority operation setting condition is satisfied or not is determined, and the mode setting control based on the condition determination is performed, the remote control side control unit 52 of the remote control 217. You may be made to do. In that case, the remote controller 217 needs to receive information (for example, speed information from the vehicle speed sensor, PKB signal, GPS signal, etc.) for determining whether or not the priority operation setting condition is satisfied from the display device 20. There is.

  In the first embodiment, the case where the remote controller 217 has a mode setting function and the display device 20 has a control function of controlling a target image source by a control signal has been described. However, the remote controller 217 may be configured to have a control function for controlling a target image source by a mode setting function and a control signal. In this case, the control signal output from the remote controller 217 controls the target image source. That is, the control unit 200 of the display device 20 functions as a relay device that only transfers a control signal from the remote controller to the target source.

  Further, even when the remote controller 217 is configured to have a mode setting function and a control function for controlling the target image source by the control signal, the above-described determination of the effective operation setting condition (first modified example) ) And priority operation setting conditions (second modified example) may be determined.

  In the first embodiment, the case where the remote controller 217 has a mode setting function and the display device 20 has a control function of controlling a target image source by a control signal has been described. However, the display device 20 may be configured to have a control function for controlling a target image source by a mode setting function and a control signal. In this case, the mode setting unit is configured by the operation unit 215 or the touch panel 124 of the display device 20, and the set mode setting information is transmitted from the display device 20 to the remote control 217 via the remote control transmission / reception unit 216. Based on the received mode setting information, the remote controller 217 displays one of the corresponding DR mode operation switch and PA mode operation switch on the remote control side display unit 53, and the remote control operation unit 54 and / or What is necessary is just to comprise so that operation input with respect to any one of DR mode and PA mode can be performed using the touchscreen contained in the remote control side display part 53. FIG. Further, the remote control side control unit 52 of the remote control 217 generates a control signal corresponding to the operation input input from the touch panel provided on the remote control side operation unit 54 or the remote control side display unit 53 of the remote control 217, and It transmits to the control part 200. The control unit 200 of the display device can be configured to identify the target image source based on the mode setting status by the mode setting unit of the display device and to control the target image source based on the control signal received from the remote controller 217. .

  Further, even when the display device 20 is configured to have a control function for controlling the target image source by the mode setting function and the control signal, the above-described determination of the effective operation setting condition (first modification) Example) and priority operation setting conditions may be determined (second modification).

  In the first embodiment, the case where the remote controller 217 has a mode setting function and the display device 20 has a control function of controlling a target image source by a control signal has been described. However, the display device 20 may have a mode setting function, and the remote controller 217 may have a control function for controlling a target image source by a control signal. In this case, the mode setting unit is configured by the operation unit 215 or the touch panel 124 of the display device 20, and the set mode setting information is transmitted from the display device 20 to the remote control 217 via the remote control transmission / reception unit 216. The remote controller 217 displays either the DR mode operation switch or the PA mode operation switch corresponding to the remote control side display unit 53 based on the received mode setting information, and the remote control operation unit 54 and / or the remote control. What is necessary is just to comprise so that operation input with respect to any one of DR mode and PA mode can be performed using the touchscreen contained in the side display part 53. FIG. Further, the remote control unit 52 of the remote control 217 generates a control signal corresponding to an operation input input from the remote control side operation unit 54 or the remote control side display unit 53 of the remote control 217. In this case, the control signal output from the remote controller 217 controls the target image source. That is, the control unit 200 of the display device 20 functions as a relay device that only transfers a control signal from the remote controller to the target source.

  Further, even when the display device 20 has a mode setting function and the remote controller 217 has a control function for controlling a target image source by a control signal, the effective operation setting condition described above is satisfied. You may comprise so that judgment (1st modification) and judgment (2nd modification) of priority operation setting conditions may be performed.

(Second Embodiment)
In the second embodiment, under the situation where the separated display is performed, the separated display is once canceled, and only one display image to be operated is displayed on the display unit 7, and then one displayed image is displayed. It is intended to control the image source corresponding to the display image. In the second embodiment, the control system itself including the display device 20 and the remote controller 217 is the same as that of the first embodiment.

  In the second embodiment, the remote controller 217 switches between a second display image (driver seat display image) 9 and a first display image (passenger seat display image) 8. A display switching unit (which also functions as an operation unit for canceling separation display). By the way, display switching determines which viewing direction of a plurality of viewing directions is to be indicated, and which of a plurality of image sources (navigation unit 206, DVD playback unit 204, etc.) is to be indicated. It also corresponds to.

  In addition, when the remote controller 217 performs display switching by a method to be described later, any one of the corresponding operation switches is displayed on the remote controller side display unit 53, and the remote controller operation unit 54 and / or the remote controller side display unit 53 is displayed. The touch panel included is used so that an operation input for either the DR mode or the PA mode can be performed.

  Further, the remote control unit 52 of the remote control 217 corresponds to a display switching signal indicating the display switching status and an operation input input from the remote control side operation unit 54 or the remote control side display unit 53 of the remote control 217. Control signal generated. Next, the remote control side control unit 52 transmits the generated display switching signal and control signal from the remote control side transmission / reception unit 55 to the remote control transmission / reception unit 216. The control unit 200 of the display device identifies a target image source based on the received display switching signal, and switches all display images displayed on the display unit 7 to display images based on image data from the target image source. After that, for example, the control unit 200 of the display device 20 that receives the control signal input by the observer using the remote controller 217 while viewing the switched display image controls the target image source based on the received control signal.

  That is, in the case of the second embodiment, the remote controller 217 has a display switching function, and the display device 20 has a control function for controlling a target image source by a control signal.

  FIG. 17 is a flowchart for explaining control contents in the second embodiment. This control is started when an observer performs an operation under a situation where separate display is performed on the display device 20. First, it is determined whether or not the operation performed on the remote controller 217 is a separate display release operation (step b1). When the release operation is performed, the control unit 200 of the display device 20 performs one-screen display on the display unit 7 (step b2).

  Which one of the driver seat display image and the passenger seat display image is to be displayed on a single screen is determined according to the contents of the release operation. For example, one release switch (display changeover switch) is provided. When the release switch is pressed once, a one-screen display based on the driver's seat display image is displayed. When the release switch is pressed again, a one-screen display is displayed based on the passenger seat display image. Thereafter, each time the release switch is pressed, the display image of the single screen display may be switched. Further, two release switches may be provided, and when one release switch is pressed, a one-screen display based on the driver seat display image is displayed, and when the other release switch is pressed, a one-screen display based on the passenger seat display image is displayed. . Alternatively, it is detected in which direction the remote controller 217 is present with respect to the display device 20, and when the remote controller 217 is in the driver's seat direction, a one-screen display is made with a driver seat display image, and in the case of the passenger seat direction. A one-screen display based on the passenger seat display image may be used.

  As the one-screen display is performed on the display device 20, the remote controller 217 sets an operation mode in which an operation can be performed on the image source corresponding to the display image of the one-screen display (step b3). . The setting of the operation mode is to display on the display unit 53 an operation switch for a one-screen display image.

  When the observer performs an operation on the remote controller 217, the control unit 200 of the display device 20 recognizes that the operation has been performed (step b4), and performs an operation control corresponding to the operation performed by the control unit 200. (Step b5). When a predetermined time elapses after the operation on the remote controller 217 is performed (step b6), the one-screen display on the display device 20 is returned to the separate display (step b7), and the operation mode is canceled on the remote controller 217 accordingly ( Step b8). That is, the operation switch for the display image of one screen display is deleted from the display unit 53 of the remote controller 217. The operation mode may be canceled by invalidating the operation of the operation switch.

  Also, when a predetermined time has passed since the release operation was performed (steps b1 to b4 and b6), the one-screen display on the display device 20 is returned to the separate display, and accordingly the remote controller 217 is displayed. The operation mode is canceled (steps b7 and b8).

According to the second embodiment, the following effects can be obtained.
(1) In the above-described embodiment, the operation is performed in a state in which the separated display is canceled and the observer displays a one-screen display that the user wants to operate. You can easily recognize what you are doing.

  (2) In the above-described embodiment, an appropriate operation mode is set in the remote controller 51 by performing an operation for canceling the separated display, so that each operation on the two display images displayed on the display device 11 is appropriately performed. It can be carried out.

  (3) In the above embodiment, the one-screen display on the display device 11 and the operation mode on the remote controller 51 return to separate display after a predetermined time, and the operation mode is canceled, so that the display is not an operation target. The inconvenience of the viewer of the image can be reduced.

  In the above description, when the one-screen display is selected, the remote controller 217 sets the operation mode for the displayed image, and the corresponding operation switch is configured by the display unit 53. However, all the operation switches for a plurality of display images may be configured by the display unit 53 so that the display on the display unit is not switched by switching the operation mode. In this case, it is necessary to perform control so that an operation on the operation switch for a display image not displayed on the display device 20 is invalid.

  The second embodiment may be modified so as to determine the effective operation setting condition on the display device 20 side (first modification of the second embodiment).

  The valid operation setting condition is, for example, that the operation to the first image source 1 corresponding to the first display image (passenger seat display image) 8 is validated, and the second display image (driver seat display). This is a condition for invalidating the operation on the second image source 2 corresponding to (image) 9. For example, if the effective operation setting condition is a condition that is satisfied when the driver is in a situation where he / she should concentrate on driving, when the driver should concentrate on driving (the control unit 200 of the display device 20 is effective) By determining whether or not the operation setting condition is satisfied and controlling the switching of the display image by the display switching signal from the remote controller 217, operation input to the second display image (driver seat display image) 9 is performed. It becomes invalid and cannot be operated by the remote controller 217. As a result, the driver is prevented from being distracted by the operation of the remote controller 217, and safety during vehicle traveling can be improved.

  That is, in the first modification of the first embodiment, the remote controller 217 has a display switching function, the display device 20 has a control function for controlling a target image source by a control signal, and the display device 20 is effective. This means that the condition determination as to whether or not the operation setting condition is satisfied and the display image switching control based on the condition determination are performed.

  FIG. 18 is a flowchart for explaining the control content performed when the valid operation setting condition is satisfied. When the effective operation setting condition is satisfied, when the separation display canceling operation is performed (step b11), the one-screen display by the display image for the passenger seat is executed on the display device 20 (step b12). Then, an operation mode (PA mode) capable of performing an operation on the passenger seat display image is set (step b13).

  When the observer operates the remote controller 217, the operation content is determined (step b14). If the operation content is a mode switching operation, it is invalidated (step b15). The invalidation process can be performed by not transmitting an operation signal to the control unit 200 of the display device 20 when the operation content is determined by the control unit 52 of the remote controller 217. In addition, when the operation content is determined by the control unit 200 of the display device 20, the invalidation process can be performed by preventing the control unit 200 from performing the mode switching process.

  If the operation content is an operation other than the mode switching operation, the operation control corresponding to the operation performed by the control unit 200 is performed (step b16). When a predetermined time elapses after the operation on the remote controller 217 is performed (step b17), the one-screen display on the display device 20 is returned to the separate display (step b18), and the operation mode is canceled on the remote controller 217 accordingly (step b18). Step b19).

  Further, when a predetermined time has passed since the release operation was performed (steps b11 to b14 and b17), the one-screen display on the display device 20 is returned to the separated display, and accordingly the remote controller 217 is displayed. The operation mode is canceled (steps b18 and b19).

  In the first modified example, the display device 20 performs the condition determination as to whether or not the effective operation setting condition is satisfied, and the display image switching is controlled based on the condition determination. However, in order to reduce the load on the control unit 200 of the display device 20, the condition determination as to whether or not the effective operation setting condition is satisfied, and the display image switching control based on the condition determination are controlled by the remote controller side control of the remote controller 217. This may be performed by the unit 52. In that case, it is necessary for the remote controller 217 to receive information (for example, speed information from the vehicle speed sensor, PKB signal, GPS signal, etc.) for determining whether or not the valid operation setting condition is satisfied from the display device 20. There is.

  The second embodiment may be further modified so as to determine the priority operation setting operation condition on the display device 20 side (second modification of the second embodiment).

  The priority operation setting condition is, for example, an operation on the second image source 2 corresponding to the second display image (display image for driver's seat) 9, the first display image (display image for the passenger seat). 8 is a condition for giving priority to an operation on the first image source 1 corresponding to 8. For example, if the priority operation setting condition is a condition that is satisfied when the driver is in a situation where he / she should concentrate on driving, when the driver should concentrate on driving (the control unit 200 of the display device 20 is effective) By controlling whether or not the operation setting condition is satisfied and controlling the switching of the display image by the display switching signal from the remote controller 217, the operation input to the second display image (driver seat display image) 9 is performed. It cannot be done easily. As a result, the driver is prevented from being distracted by the operation of the remote controller 217, and safety during vehicle traveling can be improved.

  If an operation input to the second display image (driver seat display image) 9 is required, an instruction to cancel the invalidation indicates that the second display image (driver seat display image) 9 has an operation input. Is also effective. Therefore, in the priority condition determination, the operation input to the second display image (driver seat display image) 9 is always invalidated (validity condition determination: first modification of the second embodiment). Compared to the above, the operability can be improved. The specific condition for satisfying the effective operation setting condition is the same as the effective operation setting condition.

  That is, in the second modification of the second embodiment, the remote controller 217 has a display switching function, the display device 20 has a control function of controlling the target image source by a control signal, and the display device 20 has priority. This means that the condition determination as to whether or not the operation setting condition is satisfied and the display image switching control based on the condition determination are performed.

  FIG. 19 is a flowchart for explaining the control content performed when the priority operation setting condition is satisfied. When the priority operation setting condition is satisfied, when the separation display canceling operation is performed (step b21), the one-screen display by the display image for the passenger seat is executed on the display device 20 (step b22). Then, an operation mode (PA mode) capable of performing an operation on the passenger seat display image is set (step b23).

  When the observer operates the remote controller 217, the operation content is determined (step b24). When the operation content is an operation other than the mode switching operation, the operation control corresponding to the operation performed by the control unit 200 is performed (step b25).

(Third embodiment)
In the third embodiment, both the first display image (passenger seat side display image) 8 and the second display image (driver seat side display image) 9 are supported under the situation where the separated display is performed. A remote controller 217 having all operation switches is configured so that an appropriate operation can be performed. In the third embodiment, the control system itself including the display device 20 and the remote controller 217 is the same as that of the first embodiment.

  FIG. 20 is a flowchart for explaining control contents in the third embodiment. This control is performed under the situation where the separate display is performed on the display device 20. This flowchart is repeated until the separation display is canceled. First, it is determined whether or not an effective operation setting condition for invalidating an operation on the driver seat display image and validating an operation on the passenger seat display image is satisfied (step c1). If established, the operation for the passenger seat display image is validated and the operation for the driver seat display image is invalidated (step c2). The processing for invalidation can be performed when the control unit 200 of the display device 20 does not perform operation control corresponding to the operation on the driver seat display image.

  When the observer performs an operation on the remote controller 217, the control unit 200 of the display device 20 recognizes that the operation has been performed (step c3), and the control unit 200 determines which display image the operation is for. Determination is made (step c4). When the operation is for the driver seat display image, the control unit 200 does not perform the operation control corresponding to the operation (step c5). On the other hand, if the operation is for the passenger seat display image, the control unit 200 performs operation control corresponding to the operation (step c6). Then, it returns to step c1.

  If the valid operation setting condition is not satisfied, the operation on the driver seat display image is validated and the operations on both display images are validated (step c7), and the observer operates the remote control 217. The control unit 200 of the display device 20 recognizes that the operation has been performed (step c8), and the control unit 200 performs operation control on the performed operation (step c6). Then, it returns to step c1.

According to the third embodiment, the effects can be obtained as follows.
(1) In the above embodiment, since the remote controller 217 includes all the operation switches necessary for the operation on the display image displayed on the display device 20, the mode switching operation as in the first and second embodiments is performed. Each operation on the two display images can be performed immediately without performing it. Therefore, the operability of the remote controller 217 can be improved.

  (2) If the operation for the display image for the driver's seat is invalidated and the effective operation setting condition for enabling the operation for the display image for the passenger seat is in a situation where the driver should concentrate on driving, driving When the person should concentrate on driving, the operation on the display image for the driver's seat becomes invalid and cannot be operated. As a result, the driver is prevented from paying attention to the operation of the remote controller 217, and safety during vehicle traveling can be improved. Further, since a person other than the driver, for example, a passenger in the passenger seat can operate the remote controller 217 to perform desired operation control, it can be operated comfortably. In addition, a person other than the driver can operate the remote controller 217 instead of the driver.

  The process described in the above third embodiment for enabling the operation on the passenger seat display image and invalidating the operation on the driver seat display image is performed when the operation on the driver seat display image is performed. The control unit 52 of the remote controller 217 may be substituted by preventing the control signal from being transmitted to the display device 20. In this case, since it is not necessary for the control unit 200 of the display device 20 to determine whether the control signal is valid or invalid, the load on the control device 200 of the display device 20 can be reduced.

  In the third embodiment, the observer may be informed that the operation on the driver seat display image is invalid and the operation on the passenger seat display image is valid. The notification can be performed by causing the display unit 53 of the remote controller 217 to display a character indicating that the operation on the driver seat display image is invalid or a predetermined character, whereby the observer can control the remote controller 217. When operating, it is possible to easily know whether various devices can be controlled.

Therefore, the remote controller 217 can operate the passenger seat display image, but cannot operate the driver seat display image. In addition, the control unit 200 of the display device 20 is configured to recognize that an operation on the touch panel included in the display unit 7 is an operation on the passenger seat display image.

    FIG. 21 is a flowchart for explaining control contents in the fourth embodiment. This control is performed under the situation where the separate display is performed on the display device 20. This flowchart is repeated until the separation display is canceled. First, it is determined whether or not an effective operation setting condition for invalidating an operation on the driver seat display image and validating an operation on the passenger seat display image is satisfied (step d1). If established, the operation by the remote controller 217 is validated and the operation by the touch panel is invalidated (step d2). In the processing for invalidation, when an operation is performed on the touch panel 124 of the display unit 7, the control unit 200 of the display device 20 performs an operation control corresponding to an operation on the touch panel 124, that is, an operation on the display image for the driver's seat. It can be realized by not.

  When the observer operates the remote control 217 or the touch panel of the display unit 7, the control unit 200 of the display device 20 recognizes that the operation has been performed (step d3). Further, the control unit 200 operates the remote control 217. Or an operation using a touch panel is determined (step d4). In the case of an operation on the touch panel, the control unit 200 does not perform operation control corresponding to the operation (step d5). On the other hand, when the operation is performed by the remote controller 217, the control unit 200 performs operation control corresponding to the operation (step d6). Thereafter, the process returns to step d1.

  If the valid operation setting condition is not satisfied, the operation on the touch panel is validated, and both the operation by the remote controller 217 and the operation by the touch panel are validated (step d7). When the observer operates the remote control 217 or the touch panel 124 of the display unit 7, the control unit 200 of the display device 20 recognizes that the operation has been performed (step d8), and the control unit 200 performs the operation performed. Is controlled (step d6). Thereafter, the process returns to step d1.

According to the fourth embodiment, the following effects can be obtained.
(1) In the above embodiment, the operation for the display image for the passenger seat is performed by the remote controller 217, and the operation for the display image for the driver seat is performed by the touch panel 124 of the display unit 7, so the modes as in the first and second embodiments are performed. Each operation on the two display images can be immediately performed without performing the switching operation. Therefore, the operability of the remote controller 217 can be improved.

  (2) If the operation for the display image for the driver's seat is invalidated and the effective operation setting condition for enabling the operation for the display image for the passenger seat is in a situation where the driver should concentrate on driving, driving When the person should concentrate on driving, the operation on the display image for the driver's seat becomes invalid and cannot be operated. As a result, the driver is prevented from paying attention to the operation of the touch panel, and safety during vehicle traveling can be improved. Further, since a person other than the driver, for example, a passenger in the passenger seat can operate the remote controller 217 to perform desired operation control, it can be operated comfortably.

  In the fourth embodiment, the remote controller 217 may notify the observer that an operation on the passenger seat display image is possible. As a notification method, it is conceivable to display a character indicating that an operation on the display image for the passenger seat is possible or a predetermined character on the display unit 53 of the remote controller 217. As a result, it is possible to prevent the observer from operating the remote control 217 by mistake and performing an operation on the driver seat display image, thereby improving the operability of the remote control 217.

(Fifth embodiment)
In the fifth embodiment, the positional relationship between the display device 20 and the remote controller 217 is determined under the situation where separate display is performed, and the first display image (passenger seat side display image) is determined based on the positional relationship. 8 and the second display image (driver's seat side display image) 9 are determined so that the observer wants to perform the operation input, and the operation control in the remote controller 217 is executed or prohibited. In the fifth embodiment, the control system itself including the display device 20 and the remote controller 217 is the same as that of the first embodiment.

  FIG. 22 is a flowchart for explaining control contents in the fifth embodiment. This control is performed under the situation where the separate display is performed on the display device 20. This flowchart is repeatedly performed until the separation display is canceled. First, it is determined whether or not the observer has operated the remote control 217 (step e1). If the remote control 217 is operated, the operation on the driver seat display image is invalidated and the operation on the passenger seat display image is enabled. It is determined whether or not an effective operation setting condition is satisfied (step e2).

  When the valid operation setting condition is satisfied, the direction in which the remote controller 217 exists is detected with respect to the display device 20 (step e3). When the direction in which the remote controller 217 exists is the driver's seat direction, the operation by the remote controller 217 is invalidated (step e4). The processing for invalidation can be realized by the control unit 200 of the display device 20 not performing the operation control according to the operation signal.

  On the other hand, when the direction in which the remote controller 217 exists is the passenger seat direction or another direction (for example, the rear seat direction), the control unit 200 performs operation control corresponding to the operation performed with the remote controller 51 (step e5).

  If the valid operation setting condition is not satisfied in step e2, the operation from the driver seat direction is validated and all the operations are validated regardless of the direction in which the remote controller 217 exists (step e6). Operation control corresponding to the operation performed with the remote controller 217 is performed (step e5).

As a method for detecting the direction in which the remote controller 217 is present with respect to the display device 20, for example, the following detection method can be used.
1) When the display device 20 receives an operation signal from the remote controller 217, it detects from which direction the received operation signal is transmitted.

  2) The remote controller 217 is provided with a position detection device that detects in which direction the remote controller 217 is located with respect to the display device 20. The remote controller 217 superimposes the position information detected by the position detection device on the operation signal and transmits it to the display device 20. The control unit 200 of the display device 20 detects the direction in which the remote controller 217 exists based on the received position information.

  3) The remote controller 217 is provided with a position detection device that detects in which direction the remote controller 217 is positioned with respect to the display device 20. The remote controller 217 transmits the operation signal to the display device 20 by changing the form of the signal to be transmitted according to the position information detected by the position detection device. The control unit 200 of the display device 20 detects the direction in which the remote controller 217 exists based on the received operation signal form. The signal form includes a frequency, code information to be added, and the like. For example, a method of changing the transmission frequency or changing the code information to be added depending on whether the remote controller 217 is present in the driver seat direction or the passenger seat direction can be implemented.

  4) The remote controller 217 is provided with a position detection device that detects in which direction the remote controller 217 is positioned with respect to the display device 20. The remote controller 217 changes the type of signal to be transmitted according to the position information detected by the position detection device, and transmits an operation signal to the display device 20. The control unit 200 of the display device 20 detects the direction in which the remote controller 217 exists based on the type of the received operation signal. The type of signal includes light, infrared rays, radio waves, and the like. For example, when the remote controller 217 exists in the driver's seat direction, it can be transmitted by light, and when it exists in the passenger seat direction, it can be transmitted by infrared rays.

According to the fifth embodiment, the following effects can be obtained.
(1) In the above-described embodiment, the direction in which the remote controller 217 is present is detected with respect to the display device 20, and the operation control according to the operation on the driver seat display image or the operation on the passenger seat display image is performed according to the detection direction. It can be carried out. Therefore, each operation for the two display images displayed on the display device 20 can be appropriately performed from one remote controller 217.

  (2) If the operation for the display image for the driver's seat is invalidated and the effective operation setting condition for enabling the operation for the display image for the passenger seat is in a situation where the driver should concentrate on driving, driving When the person should concentrate on driving, the operation on the display image for the driver's seat becomes invalid and cannot be operated. As a result, the driver is prevented from paying attention to the operation of the remote controller 217, and safety during vehicle traveling can be improved. Further, since a person other than the driver, for example, a passenger in the passenger seat can operate the remote controller 217 to perform desired operation control, it can be operated comfortably. In addition, a person other than the driver can operate the remote controller 217 instead of the driver.

  In the fifth embodiment, the process of invalidating the operation by the remote controller 217 may be performed by the control unit 52 of the remote controller 217 not transmitting an operation signal to the display device 20. In this case, the load on the control unit 200 of the display device 20 can be reduced.

  In the fifth embodiment, the observer may be notified that the operation on the driver seat display image is invalid and the operation on the passenger seat display image is valid. As a notification method, it is conceivable to display a character indicating that the operation on the driver seat display image is invalid or a predetermined character on the display unit 53 of the remote controller 217. As a result, the observer can easily know whether or not various devices can be controlled by operating the remote controller 217.

  Note that the fifth embodiment may be implemented in combination with the first to third embodiments described above. That is, when the valid operation setting condition is satisfied, the control for invalidating the operation for the driver seat display image performed from the remote controller 217 as in the first to third embodiments, and the fifth embodiment Further, it may be implemented in combination with a control that disables the operation when the remote controller 51 is operated from the driver seat direction.

  In the first, second, and fifth embodiments, it is preferable to notify the observer which image source for which viewing direction can be operated with the remote control at that time. The notification can be performed by causing the display unit 53 of the remote controller 217 to display a predetermined character, symbol, character, or the like indicating the current operable mode (mode that can be operated by the remote controller). By such a method, the observer can confirm the current operable mode only by looking at the remote controller 217. It should be noted that a predetermined character, symbol, character, or the like indicating the above-described current operable mode (mode that can be operated by the remote controller) is displayed on a screen corresponding to all viewing directions of the display unit 7 of the display device 20. Anyway.

  In the first, second, and fifth embodiments described above, the image source for the viewing direction that can be operated by the remote control is switched (from DR mode to PA mode, from PA mode to DR mode, etc.) It is preferable to notify. The notification can be performed by displaying a predetermined character, symbol, character, or the like indicating “switch” on the display unit 53 of the remote controller 217. By such a method, the observer can confirm that “switching” has occurred only by looking at the remote controller 217. Note that a predetermined character, symbol, character, or the like indicating that the above-described “switching” has occurred may be displayed on a screen corresponding to all viewing directions of the display unit 7 of the display device 20.

  In the above first to fifth embodiments, the case where the remote controller 217 having the remote controller side display unit 53 is used as illustrated in FIG. 10 has been described. However, the present invention can also be applied to a control system that uses a remote controller that does not have the remote controller side display unit 53. For example, in the case of the first embodiment, a mode setting button and a group of buttons common to all modes may be prepared, and the common button may be used in accordance with the mode setting. When a specific mode (for example, DR mode) is set, control signals related to buttons not used in that mode may not be output from the remote control, or the display device 20 determines that the control signal is invalid. Also good.
