Description

The present invention relates to a display device , and more particularly to a display device for performing appropriate control on an image displayed on a display screen.

  While the vehicle is traveling, the driver is prohibited from watching the television and movies, and the current display device cannot display the television or movies while the vehicle is traveling. For this reason, passengers other than the driver (for example, passengers next to the driver) cannot watch TV or movies while driving, even though they are not prohibited from watching TV or movies. .

On the other hand, in recent years, various technologies have been proposed for making display content for a driver different from display content for a passenger other than the driver in a display device mounted on a vehicle. For example, in Patent Document 1 below, as shown in FIG. 13, the light emitted from the belt-like display unit 4 that provides the light shielding bands 2 and 3 on the transparent cover 1 and displays the driver seat image G _DR is although entering the eyes of the driver DR, the light emitted from the Workspace window 5 for displaying the passenger seat picture G _PA is prevented from being incident on the eyes of the driver DR, while the image G _PA passenger The light emitted from the belt-like display unit 5 to be displayed is incident on the eyes of the passenger seat occupant PA, while the light emitted from the belt-like display unit 4 that displays the driver seat image _GDR is in the eyes of the passenger seat passenger PA. A technique for preventing incidence is disclosed.

  By adopting such a technique, as shown in FIG. 14, the map image 7 by the navigation device is displayed on the display device 6 so that it can be seen from the driver DR (so that it cannot be seen from the passenger occupant PA). The DVD image 8 can be displayed on the display device 6 so as to be seen from the passenger occupant PA (not seen from the driver DR). Thus, even when the vehicle is traveling, the passenger occupant PA can watch TV, movies, and the like.

By the way, in recent display devices, a touch panel is adopted, and an operation switch is created on the display screen. Therefore, when the display contents for the driver and the display contents for the passengers other than the driver are different, as shown in FIG. 15, the operation switches B _{D1 to} B _D6 for the respective display contents are displayed on the display screen. , B _{A1 to} B _A6 may be displayed.

The operation switches B _{D1 to} B _D6 can be seen only by the driver, and the operation switches B _{A1 to} B _A6 can be seen only by the passenger on the passenger seat, but as shown in FIG. The switches B _{D1 to} B _D6 are arranged at the same locations P _{1 to} P ₆ on the display screen as the operation switches B _{A1 to} B _A6, respectively. Therefore, for example, if the location P ₅ on the display screen is pressed, it should implement a control performed when the operation switch B _D5 "Details" is pressed (control of detailed display the map image), an operation switch B _{A5 It} is necessary to appropriately determine whether or not to perform control (control to stop reproduction of DVD video) performed when “Stop” is pressed. In other words, if this determination cannot be made properly, appropriate operation control desired by the user cannot be performed.

Therefore, it is possible to prevent an operation performed simultaneously with the switching from being an erroneous operation.
Further, the operation control device (1) according to the reference example has a first video display that is visible from the first direction and not visible from the second direction, and is visible from the second direction. An operation control device for performing operation control under a situation in which a second video display invisible from a direction is simultaneously performed on the same screen, the first video and the second video When an operation to an operation switch that can correspond to any of the above is performed, it can be seen from the direction in which the priority operator among the persons existing in the first direction and the persons existing in the second direction exists. An operation control unit that performs operation control according to the operation on the video is provided.

According to the operation control device (1), an operation that can correspond to both the first video (for example, the driver seat video G _DR ) and the second video (for example, the passenger seat video G _PA ). When an operation is performed on a switch (for example, an operation switch arranged in the same place as the operation switches 43 _DR and 43 _PA shown in FIG. 4 described later), a person existing in the first direction ( For example, an operation control according to the operation is performed on a driver DR) and an image seen from the direction in which the priority operator among the persons in the second direction (for example, passenger occupant PA) exists. Is called. That is, no operation control is performed on the video viewed from the direction where the priority operator does not exist.

For example, if the passenger PA is when it is set to the priority operator operation to the operation switch may correspond to any of the image for the driver's seat G _DR and the passenger seat picture G _PA is performed, only the operation for the passenger seat picture G _PA is enabled, operations on the image for the driver's seat G _DR becomes invalid. Therefore, the user can realize desired operation control by appropriately setting and switching the priority operator and accurately recognizing which of the priority operators is set.

As described above, even if an operation switch that can handle both the driver seat image _GDR and the passenger seat image _GPA is operated, the operation control desired by the user is realized. Can do. In other words, since operation switches having different properties can be arranged at the same place like the operation switches 43 _DR and 43 _PA shown in FIG. 4, the display screen can be used more effectively.

  According to the operation control device (6), the person who has indicated the intention to perform the operation (for example, the driver DR, the passenger occupant PA) is set as the priority operator for the predetermined period. For example, when a dedicated operation switch for setting the priority operator as the driver DR is pressed by the driver DR, the driver DR is set as the priority operator.

  Accordingly, since the priority operator can be set by the user's intention display, the user can freely set the user himself / herself as the priority operator when performing an operation. In addition, since the user performs the setting of the priority operator, it is possible to easily recognize which of the two (for example, the driver DR and the passenger occupant PA) is the priority operator.

Examples of the predetermined period include the following a to d.
a) Period until the next operation is performed.
b) A period until the next operation is performed or a period until a predetermined time (for example, 10 seconds) elapses.
c) A period until a time during which no operation is performed exceeds a predetermined time (for example, 10 seconds).
d) A period until the priority operator is newly set.

Moreover, as a method of performing the said intention display, the following ae are mentioned, for example.
a) Operation switches for setting the driver DR and the passenger occupant PA as the priority operator are provided independently.

The processing operation [1-1] performed by the control unit 12 in the display device 11 employing the operation control device according to the embodiment (1) will be described based on the flowchart shown in FIG. In this processing operation [1-1], a separate display for allowing the driver _DR to visually _{recognize the} driver's seat image _GDR and for the passenger seat passenger _PA to visually recognize the passenger's seat image _GPA is displayed on the display unit. 13 is an operation performed when an instruction is given from the user by operating the operation switch formed on the operation unit 13, the operation unit 14, or the like.

When the separate display is instructed, first, based on a predetermined condition, one of the two images is displayed as the driver seat image _GDR , and the rest is displayed as the passenger seat image _GPA (step S1). Next, as shown in FIG. 4, a priority member setting switch 41 _DR for setting the driver DR as a priority operator is formed at the upper right of the driver seat image G _DR and the passenger seat image G _PA is formed. Priority setting switch 41 _PA for setting the passenger seat PA as the priority operator is formed at the upper left of (step S2). As a method of separate display, for example, when a map image for guiding to a destination is displayed, the map image is used as a driver seat image _GDR , and a television image or a movie is used for a passenger seat. and a method such that the image _{G PA.}

Next, release switches 42 _DR and 42 _PA for releasing the separation display are formed in the driver seat image G _DR and the passenger seat image G _PA respectively (step S3), and then the separation display is performed. the separated display flag _{f SE} to indicate that to 1 (step S4). FIG. 4A is a diagram showing an example of the driver seat video _GDR , and FIG. 4B is a diagram showing an example of the passenger seat video G _PA .

The operation switches 43 _{DR to} 48 _DR provided in the driver seat image G _DR and the operation switches 43 _{PA to} 48 _PA provided in the passenger seat image G _PA are provided in the same place. Both the driver seat image G _DR and the passenger seat image G _PA can be supported. Here, the frame line of the operation switches 43 _{PA to} 48 _{PA and} the frame line of the operation switch 49 _PA , which will be described later, are bold lines, and the passenger seat passenger PA is set as the priority operator. The user can easily recognize that the operation for the seat video _GPA is possible.

On the other hand, the priority setting switch 41 _DR , the release switch 42 _DR , and the operation switch 49 _DR can be adapted to only the driver seat video G _DR , and the priority setting switch 41 _PA and the release switch The 42 _PA and the operation switch 49 _PA can be adapted only to the passenger seat image G _PA . Further, the operation switch 14a~14h which are arranged around the display unit 13, the image for the driver's seat G _DR, and either a or what may also support the passenger seat picture G _PA, may correspond to only one There is something.

Next, the processing operation [1-2] performed by the control unit 12 in the display device 11 employing the operation control device according to the embodiment (1) is based on the flowcharts shown in FIGS. I will explain. Note that this processing operation [1-2] is performed by operating switches and operations formed on the display unit 13 by the user when the separated display is performed (that is, when the separated display flag _fSE is 1). This is an operation performed when the unit 14 or the like is operated.

First, it is determined whether or not the priority setting switch 41 _DR for setting the driver DR as a priority operator has been operated (step S11), and if it is determined that the priority setting switch 41 _DR has been operated, then Then, it is determined whether or not the driver flag _fDR indicating that the driver _DR is set as the priority operator is 1 (step S12).

If it is determined that the driver flag _fDR is not 1 (that is, the driver DR is not set as the priority operator), then the passenger seat indicating that the passenger seat occupant PA is set as the priority operator is displayed. It is determined whether or not the occupant flag _fPA is 1 (step S13). Passenger flag _{f PA} is 1 (i.e., the passenger PA is set to the priority operator) When it is judged that, the operation switch ₄₃ PA _{to 49 PA} provided video _{G PA} passenger slimming border (step S14), and the time that the operation for the passenger seat picture G _PA is not performed (i.e., time from last operation) the timer t _PA stops for measuring (step S15), and the assistant return the seat occupant flag _{f PA} to 0 (step S16), and then proceeds to step S17. On the other hand, in step S13, if the passenger flag _{f PA} is not 1 determines, skip steps S14 to S16, the process directly proceeds to step S17.

Next, thicker borders of the operation switch ₄₃ DR _{to 49 DR} provided in the image for the driver's seat _{G DR} (step S17), the operation for the image for the driver's seat _{G DR} is not performed time (i.e., the last operation Timer _tDR for measuring (time from) is started with 0 (step S18), the driver flag _fDR is set to 1 (step S19), and then the driver DR is set as the priority operator. In order to inform the user of the fact, the buzzer sound is generated by controlling the buzzer sound generator 15 (step S20). In step S12, if it is determined that the driver flag _fDR is 1 (that is, the driver DR has already been set as a priority operator), the timer _tDR is returned to 0 (step S21) and remains as it is. The processing operation [1-2] ends.

On the other hand, if it is determined in step S11 that the priority setting switch _41DR is not operated, whether or not the priority setting switch 41 _PA for setting the passenger occupant PA as the priority operator is operated next. (Step S22), and if it is determined that the priority set switch 41 _PA has been operated, it is next determined whether or not the passenger seat occupant flag _fPA is 1 (step S23).

If it is determined that the passenger seat occupant flag f _PA is not 1 (that is, the passenger seat occupant PA is not set as the priority operator), it is then determined whether or not the driver flag f _DR is 1 ( Step S24). Driver flag _{f DR} is 1 (i.e., the driver DR is set to the priority operator) When it is judged that the operation provided in the image for the driver's seat _{G DR} switch ₄₃ DR _{to 49 DR} borders (Step S25), the timer _tDR is stopped (step S26), the driver flag _fDR is returned to 0 (step S27), and then the process proceeds to step S28. On the other hand, in step S24, if the driver flag _{f DR} is not 1 determines, skip steps S25 to S27, the process proceeds directly to step S28.

Next, thicker borders provided operating switches ₄₃ PA _{to 49 PA} in the passenger seat video _{G PA} (step S28), the timer _{t PA} is activated to 0 (step S29), the passenger flag f _PA is set to 1 (step S30), and then a buzzer sound is generated by controlling the buzzer sound generating unit 15 to inform the user that the passenger occupant PA has been set as the priority operator. (Step S31). If it is determined in step S23 that the passenger seat occupant flag f _PA is 1 (that is, the passenger seat occupant PA has already been set as a priority operator), the timer t _PA is returned to 0 (step S32). Then, the processing operation [1-2] is finished as it is.

On the other hand, if it is determined in step S22 that the priority setting switch 41 _PA is not operated (that is, none of the priority setting switches 41 _DR and 41 _PA is operated), step S41 (FIG. 5-2). Then, it is determined which operation other than the priority setting switches 41 _DR and 41 _PA has been performed.

If it is determined that an operation switch (for example, operation switches 43 _{DR to} 48 _DR , 43 _{PA to} 48 _PA ) that can correspond to both the driver seat image G _DR and the passenger seat image G _PA is operated, If it is determined whether or not the driver flag _fDR is 1 (step S42), it is determined that the driver flag _fDR is 1 (that is, the driver DR is set as a priority operator). , to the video _{G DR} for the driver's seat, do control in accordance with the operation (step S43), then returns the timer _{t DR} to 0 (step S44).

On the other hand, if the driver flag _{f DR} is not 1 determines, then it is determined whether or not the passenger flag _{f PA} is 1 (step S45), 1 is passenger flag _{f PA} ( That is, if it is determined that the passenger seat occupant PA is set as the priority operator), the operation control is performed on the passenger seat video _GPA according to the operation (step S46), and then the timer t _{PA is set} to 0. (Step S47). If passenger flag f _PA is not 1 determines, considered as erroneous the operation, and terminates the processing operation [1-2].

If it is determined in step S41 that an operation switch (for example, the operation switch 49 _DR ) that can handle only the driver seat image G _DR has been operated, then whether or not the driver flag f _DR is 1 is determined. (Step S48), and if it is determined that the driver flag _fDR is 1 (that is, the driver DR is set as a priority operator), operation control corresponding to the operation is performed (step S49). Thereafter, the timer _tDR is returned to 0 (step S50). On the other hand, if it is determined that the driver flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [1-2] is terminated as it is.

If it is determined in step S41 that an operation switch (for example, the operation switch 49 _PA ) that can handle only the passenger seat image G _PA has been operated, then whether or not the passenger seat occupant flag f _PA is 1 is determined. If it is determined (step S51) and it is determined that the passenger seat occupant flag f _PA is 1 (that is, the passenger seat occupant PA is set as a priority operator), operation control corresponding to the operation is performed (step S51). After that, the timer t _PA is returned to 0 (step S53). On the other hand, if not 1 determination passenger flag f _PA, considered as erroneous the operation, and terminates the processing operation [1-2].

If it is determined in step S41 that the release switch 42 _DR provided in the driver seat image _GDR for releasing the separation display has been operated, it is next determined whether or not the driver flag _fDR is 1. If it is determined (step S54) and it is determined that the driver flag _fDR is 1, the priority setting switches _41DR and _41PA and the release switches _42DR and _42PA are deleted from the screen (step S55). Of the two images, the driver seat image _GDR is erased, the passenger seat image _GPA is displayed in full screen (step S56), the timers _tDR and _tPA are stopped (step S57), and the driver flag f _DR, return the passenger flag _{f PA} to 0 (step S58), then returns the separated display flag _{f SE} to 0 (step S59). On the other hand, if it is determined that the driver flag _fDR is not 1, the operation is regarded as an erroneous operation, and the processing operation [1-2] is terminated as it is.

In step S41, provided in the passenger seat video G _PA, when it is judged that the release switch 42 _PA for releasing the separated display is operated, then whether or not the passenger flag f _PA 1 (Step S60), and if it is determined that the passenger seat occupant flag _fPA is 1, the priority setting switches _41DR and _41PA and the release switches _42DR and _42PA are deleted from the screen (step S61). ) Of the two images, the passenger seat image _GPA is erased and the driver seat image _GDR is displayed on the full screen (step S62), and then the process proceeds to step S57.

Next, the processing operation [1-3] performed by the control unit 12 in the display device 11 in which the operation control device according to the embodiment (1) is adopted will be described based on the flowchart shown in FIG. The processing operation [1-3] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, it is determined whether or not the driver flag _fDR is 1 (step S71). If it is determined that the driver flag _fDR is 1, then the timer _tDR is set to a predetermined time T (for example, 10 seconds) or longer (step S72), and if it is determined that the timer _tDR is longer than the predetermined time T (that is, 10 seconds have passed since the last operation). Then, the operation switches 43 _DR to 49 _DR provided in the driver seat video G _DR are thinned (step S 73), the timer t _DR is stopped (step S 74), and the driver flag f _DR is returned to 0 (step S 73). Step S75). On the other hand, if it is determined that the timer _tDR is not equal to or longer than the predetermined time T, the processing operation [1-3] is terminated as it is.

If it is determined in step S71 that the driver flag _fDR is not 1, then it is determined whether or not the passenger seat occupant flag _fPA is 1 (step S76), and the passenger seat occupant flag _fPA is If it is determined that the timer t _PA is equal to 1, then it is determined whether or not the timer t _PA is equal to or longer than the predetermined time T (step S77), and the timer t _PA is equal to or longer than the predetermined time T (ie, the last operation is performed). if it is determined that has elapsed 10 seconds being performed), thinner borders of the operation switch ₄₃ PA _{to 49 PA} provided video _{G PA} passenger (step S78), stops the timer _{t PA} is (step S79), it returns the passenger flag _{f PA} to 0 (step S80). On the other hand, when it is determined that the timer t _PA is not equal to or greater than the predetermined time T, or when it is determined that the passenger seat occupant flag f _PA is not 1, the processing operation [1-3] is terminated.

According to the operation control device according to the embodiment (1), operation switch may correspond to any of the image for the driver's seat G _DR and the passenger seat picture G _PA (e.g., an operation switch 43 _DR shown in FIG. 4 ~ 48 _DR , 43 _PA ~ 48 _PA , when the operation to the operation switch is performed in the same place) from the direction in which the priority operator of the driver DR and passenger seat passenger PA exists Operation control corresponding to the operation is performed on the visible video. That is, no operation control is performed on the video viewed from the direction where the priority operator does not exist.

For example, if the passenger PA is when it is set to the priority operator operation to the operation switch may correspond to any of the image for the driver's seat G _DR and the passenger seat picture G _PA is performed, passenger only operations for seat picture G _PA is enabled, operations on the image for the driver's seat G _DR becomes invalid. Accordingly, the user can realize desired operation control by appropriately setting or switching the priority operator or by accurately recognizing which priority operator is set.

As described above, even if an operation switch that can handle both the driver seat image _GDR and the passenger seat image _GPA is operated, the operation control desired by the user is realized. Can do. In other words, since the operation switches 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA shown in FIG. 4 can be provided with operation switches having different properties in the same place, the display screen can be used more effectively. can do.

  In the operation control apparatus according to the above embodiment (1), the driver DR and the passenger occupant PA are treated equally. However, since the driver DR needs to be careful of driving, the driver DR operates the driver DR. It is better to add restrictions. However, there is no need to consider operational restrictions for the passenger occupant PA. Therefore, in another embodiment, the passenger occupant PA may be set as the priority operator during normal times. That is, when the driver DR is not set as the priority operator, the passenger seat occupant PA is set as the priority operator.

In addition, in the operation control device according to another embodiment, when one of the driver DR and the passenger occupant PA is set as a priority operator, it cannot be seen from the direction in which the priority operator exists. The video may be temporarily deleted from the display unit 13 to form a state in which operation control according to the operation on the video is not performed. For example, when the driver DR is set to the priority operator erases the passenger seat picture G _PA from the display unit 13, so that the operation control in response to an operation to the passenger seat picture G _PA not performed . Thereby, an erroneous operation can be prevented more reliably.

In the operation control device according to the above embodiment (1), the priority setting switch 41 _DR for setting the driver DR as the priority operator and the priority for setting the passenger seat occupant PA as the priority operator are provided. The operator setting switch 41 _PA is provided, but the operation control device according to another embodiment is provided with a toggle switch that can alternately switch between the two states each time the same operation is performed. May be.

  FIG. 7 is a block diagram schematically showing a main part of an AV / navigation system including a display device employing the operation control device according to the embodiment (2). However, the same components as those in the AV / navigation system shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted here. In the figure, reference numeral 51 denotes a display device mounted at the center of the instrument panel of the vehicle. The display device 51 includes various electronic devices (for example, the audio device 21) mounted on the same vehicle via the bus line BL. , A navigation device 31) is connected.

  The display device 51 includes a control unit 52 including a CPU, ROM, RAM, and the like (not shown), a display unit 13, an operation unit 14 including various operation switches 14a to 14h (see FIG. 2), and a buzzer sound generation unit. 15. A vehicle speed sensor and a parking brake on / off sensor (not shown) are connected to the control unit 52 so that vehicle speed information and parking brake on / off information can be acquired.

  The control part 52 transmits the data regarding the operation command input via the operation switch (not shown) provided in the display part 13 or operation switch 14a-14h to various electronic devices (the audio apparatus 21, the navigation apparatus 31). In addition, based on data sent from various electronic devices in response to this, information indicating the operating state and operation status of various electronic devices can be displayed on the display unit 13. . Further, the control unit 52 performs, as the processing operation [2-1], the same operation as the processing operation [1-1] performed by the control unit 12 (see FIG. 1) illustrated in FIG. 3 (separate display according to an instruction from the user). Can be performed).

Next, the processing operation [2-2] performed by the control unit 52 in the display device 51 in which the operation control device according to the embodiment (2) is employed will be described based on the flowchart shown in FIG. The processing operation [2-2] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, based on the vehicle speed information, it is determined whether the vehicle speed v is equal to or higher than a predetermined speed V (for example, 60 km / h) (step S81), and the vehicle speed v is equal to or higher than the predetermined speed V (ie, high If it is determined that the vehicle is traveling at a speed and the setting condition for setting the passenger occupant PA as the priority operator is satisfied), then it is determined whether or not the passenger occupant flag f _PA is 1. (Step S82).

If it is determined that the passenger seat occupant flag f _PA is not 1 (that is, the passenger seat occupant PA is not set as the priority operator), the process proceeds to step S83 to set the passenger seat occupant PA as the priority operator. Process. The processing operations in steps S83 to S90 are the same as the processing operations in steps S24 to S31 performed by the control unit 12 shown in FIG.

After the process of step S90, a setting condition satisfaction flag F _PA for indicating that the setting condition for setting the passenger occupant PA as the priority operator is satisfied is set to 1 (step S91). If it is determined in step S82 that the passenger seat occupant flag _fPA is 1 (that is, the passenger seat occupant PA has already been set as the priority operator), the routine proceeds to step S91, where the setting condition establishment flag F is set. _{Set PA} to 1.

If it is determined in step S81 that the vehicle speed v is not equal to or higher than the predetermined speed V, it is next determined whether or not the setting condition establishment flag F _PA is 1 (step S92), and the setting condition establishment flag F _{PA is determined.} If it is determined that 1 is 1, it is determined whether or not the vehicle speed v is equal to or lower than a predetermined speed (V−α) based on the vehicle speed information (step S93). The numerical value α is a positive number and serves as a buffer region.

If it is determined that the vehicle speed v is equal to or lower than a predetermined speed (V−α) (that is, the setting condition for setting the passenger occupant PA as the priority operator has not been established), the setting condition establishment flag F _PA is set. Return to 0 (step S94). On the other hand, if it is determined that the vehicle speed v is not less than or equal to the predetermined speed (V−α), the processing operation [2-2] is terminated as it is. Also, if it is determined in step S92 that the setting condition satisfaction flag F _PA is not 1, the processing operation [2-2] is ended as it is.

Next, the processing operation [2-3] performed by the control unit 52 in the display device 51 in which the operation control device according to the embodiment (2) is adopted will be described based on the flowchart shown in FIG. This processing operation [2-3] is performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, based on the on / off information of the parking brake, it is determined whether or not the parking brake is on (step S101), and the parking brake is on (that is, the vehicle is stopped and the driver If it is determined that the setting condition for setting DR as the priority operator is satisfied, it is then determined whether or not the driver flag _fDR is 1 (step S102).

If it is determined that the driver flag _fDR is not 1 (that is, the driver DR is not set as a priority operator), the process proceeds to step S103 to perform a process for setting the driver DR as a priority operator. . The processing operations in steps S103 to S110 are the same as the processing operations in steps S13 to S20 performed by the control unit 12 shown in FIG.

After the process of step S110, a setting condition satisfaction flag _FDR for indicating that a setting condition for setting the driver DR as a priority operator is satisfied is set to 1 (step S111). If it is determined in step S102 that the driver flag _fDR is 1 (that is, the driver DR has already been set as a priority operator), the process proceeds to step S111, where the setting condition establishment flag _fDR is set. Set to 1.

If it is determined in step S101 that the parking brake is not on (that is, the setting condition for setting the driver DR as the priority operator has not been established), then the setting condition establishment flag _FDR is set. It is determined whether or not it is 1 (step S112). If it is determined that the setting condition establishment flag _FDR is 1, the setting condition establishment flag _FDR is returned to 0 (step S113). On the other hand, if it is determined that the setting condition satisfaction flag _FDR is not 1, the processing operation [2-3] is terminated as it is.

Next, the processing operation [2-4] performed by the control unit 52 in the display device 51 employing the operation control device according to the embodiment (2) will be described based on the flowchart shown in FIG. Note that this processing operation [2-4] is performed by operating switches and operations that are formed on the display unit 13 by the user when the separated display is performed (that is, when the separated display flag _fSE is 1). This is an operation performed when the unit 14 is operated.

First, it is determined whether or not the priority setting switch 41 _DR for setting the driver DR as the priority operator is operated (step S121). If it is determined that the priority setting switch 41 _DR is operated, then Then, it is determined whether or not the setting condition establishment flag F _PA is 1 (step S122), and the setting condition establishment flag F _PA is 1 (that is, the setting condition for setting the passenger seat occupant PA as the priority operator) Is determined), the operation of the priority setting switch 41 _DR is invalidated, and the processing operation [2-4] is terminated as it is.

On the other hand, if it is determined that the setting condition satisfaction flag F _PA is not 1, the process proceeds to step S123, and a process for setting the driver DR as the priority operator is performed. Note that the processing operation of step S123 is the same as the processing operation of steps S12 to S21 performed by the control unit 12 shown in FIG.

If it is determined in step S121 that the priority setting switch _41DR is not operated, whether or not the priority setting switch 41 _PA for setting the passenger occupant PA as the priority operator is operated next. (Step S124), and if it is determined that the priority setting switch 41 _PA has been operated, it is next determined whether or not the setting condition establishment flag _FDR is 1 (step S125). If it is determined that _FDR is 1 (that is, the setting condition for setting the driver DR as the priority operator is satisfied), the operation of the priority set switch 41 _PA is invalidated and the processing operation [ 2-4].

On the other hand, if it is determined that the setting condition establishment flag _FDR is not 1, the process proceeds to step S126, and a process for setting the passenger seat occupant PA as the priority operator is performed. Note that the processing operation in step S126 is the same as the processing operation in steps S23 to S32 performed by the control unit 12 shown in FIG. 5A, and therefore the description thereof is omitted here.

Further, the control unit 52 in the display device 51 adopting the operation control device according to the embodiment (2) performs the processing operation [1--5] performed by the control unit 12 illustrated in FIG. 6 as the processing operation [2-5]. 3] (operation for performing separate display according to an instruction from the user) can be performed. However, the processing operation [2-5] is performed when the separation display is performed (that is, when the separation display flag _fSE is 1) and the setting condition establishment flags F _DR and F _PA are not 1. This is an operation performed every predetermined period.

  According to the operation control device according to the above embodiment (2), while the setting condition for setting either the driver DR or the passenger occupant PA as the priority operator is satisfied, The corresponding person is set as the priority operator. Thus, for example, when further attention to vehicle driving is required, the passenger's seat occupant PA is set as a priority operator, and a state in which the driver DR cannot be operated is formed, thereby improving vehicle driving safety. Can be increased.

  FIG. 11 is a block diagram schematically showing a main part of an AV / navigation system including a display device employing the operation control device according to the embodiment (3). However, the same components as those in the AV / navigation system shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted here. In the figure, reference numeral 61 denotes a display device mounted at the center of the instrument panel of the vehicle. The display device 61 includes various electronic devices (for example, an audio device 21A) mounted on the same vehicle via the bus line BL. , A navigation device 31A) is connected.

  The display device 61 includes a control unit 62 including a CPU, ROM, RAM, and the like (not shown), a display unit 13, an operation unit 14 including various operation switches 14a to 14h (see FIG. 2), and a buzzer sound generation unit. 15. CD playback end information indicating that CD playback has ended is supplied from the audio device 21A to the bus line BL, and the navigation device 31A will soon arrive at the traffic jam encounter information indicating that a traffic jam will be encountered and the destination. Destination approach information indicating the above is supplied to the bus line BL, and the control unit 62 can acquire the CD reproduction end information, traffic jam encounter information, destination approach information, and the like.

  The control unit 62 transmits data related to operation commands input via operation switches (not shown) provided on the display unit 13 and operation switches 14a to 14h to various electronic devices (audio device 21A, navigation device 31A). In addition, based on data sent from various electronic devices in response to this, information indicating the operating state and operation status of various electronic devices can be displayed on the display unit 13. .

  Further, the control unit 62 performs the processing operations [1-1] and FIG. 5-1 shown in FIG. 3 performed by the control unit 12) (see FIG. 1) as the processing operations [3-1] to [3-3]. The processing operation [1-2] shown in FIG. 5-2 and the processing operation [1-3] shown in FIG. 6 can be performed.

Next, the processing operation [3-4] performed by the control unit 62 in the display device 61 in which the operation control device according to the embodiment (3) is adopted will be described based on the flowchart shown in FIG. The processing operation [3-4] is an operation performed every predetermined period when the separated display is performed (that is, when the separated display flag _fSE is 1).

First, it is determined whether or not traffic jam encounter information or destination approach information has been received (steps S131 and S132), and traffic jam encounter information or destination approach information has been received (that is, a map that provides guidance to the destination). When it is judged that the image is important video), then, it is determined whether the map image is the image for the driver's seat G _DR (step S133).

If it is determined that the map image is the image for the driver's seat G _DR, the program proceeds to step S134, performs processing for setting the driver DR priority operator. Note that the processing operation of step S134 is the same as the processing operation of steps S12 to S21 performed by the control unit 12 shown in FIG.

Meanwhile, the map image is not the image for the driver's seat G _DR (i.e., passenger seat is a picture G _PA) When it is judged that, the process proceeds to step S135, processing for setting a priority operator passenger PA I do. Note that the processing operation of step S135 is the same as the processing operation of steps S23 to S32 performed by the control unit 12 shown in FIG. If it is determined in steps S131 and S132 that neither the traffic jam encounter information nor the destination approach information has been received, it is next determined whether or not CD reproduction end information has been received (step S136). If it is determined that the CD playback end information has been received (that is, the playback status video indicating the CD playback status is an important video), it is next determined whether or not the playback status video is the driver seat video _GDR. Judgment is made (step S137).

If it is determined that the reproduction state image is the image for the driver's seat G _DR, the program proceeds to step S138, performs processing for setting the driver DR priority operator. Meanwhile, the reproduction state image is not the image for the driver's seat G _DR (i.e., passenger seat is a picture G _PA) When it is judged that, the process proceeds to step S139, for setting the passenger PA in the priority operator Process. If it is determined in step S136 that the CD playback end information has not been received, the processing operation [3-4] is ended as it is.

According to the operation control device according to the above embodiment (3), the operation switch (for example, the operation switch shown in FIG. 4) that can correspond to both the map video in the navigation device 31A and the reproduction status video in the audio device 21A. When an operation is performed on the operation switch disposed in the same place, such as 43 _{DR to} 48 _DR and 43 _{PA to} 48 _PA , an important video (for example, Operation control corresponding to the operation is performed on a video having a high possibility of being operated). That is, no operation control is performed on the non-important video.

For example, the operation switch reproduction status image displayed as an image G _PA passenger seat when it is set to the key image, which may correspond to any of the image for the driver's seat G _DR and the passenger seat picture G _PA When the operation is performed, only the operation for the passenger seat image _GPA is valid, and the operation for the driver seat image _GDR is invalid. Therefore, it is possible to validate the operation control for an image that requires more user operation.

  In the operation control device according to the above embodiments (1) to (3), intention display information and vehicle environment information (for example, vehicle speed information, parking brake on / off information, traffic jam encounter information, By setting the priority operator and important video by using the road type information (general road, highway, etc.)) as a trigger, it is possible to realize appropriate operation control desired by the user. In another embodiment, the priority operator may be switched every predetermined period. For example, the priority operator is switched in the order of driver DR, passenger occupant PA, driver DR, and passenger occupant PA for each predetermined period. Thereby, simplification of operation can be achieved. In addition, since the processing is simplified, the processing load can be reduced.

In addition, as said predetermined period, the following ac are mentioned, for example.
a) A period until a certain period (for example, 20 seconds) elapses.
b) A period until a time when no operation is performed exceeds a predetermined time (for example, 10 seconds).
c) A period until switching of the priority operator is instructed by another trigger (for example, an operation by the user).

  In still another embodiment, when the priority operator is switched, a period (for example, 3 seconds) in which neither is set as the priority operator may be provided. For example, when the priority operator switches from the driver DR to the passenger seat occupant PA, there is a period during which the operation from either of the two is not accepted, but the operation performed simultaneously with the switching is performed. It is possible to prevent erroneous operation.
