Japanese Patent Laid-Open No. 9-34418 JP 2004-42684 A

  Although not described in the techniques according to Patent Documents 1 and 2, as compared with the “short press” when switching the normal screen as the operation procedure of the operation switch to transition from the normal information display screen to the setting screen. The transition condition is to perform “long press” for a relatively long time. And when it is at the time of non-traveling, such as a vehicle stop, the transition to a setting screen will be performed.

  With such a technique, since a complicated operation on the setting screen by the driver who is a user is suppressed, safe driving of the vehicle can be ensured, but there are the following problems.

  That is, when the vehicle is in a running state, in other words, in a non-stop state, the above transition condition is satisfied by “long pressing” of the operation switch, but the transition of the setting screen is prohibited for such an operation request of the user. The setting screen is not displayed. If the user is a beginner who is unfamiliar with the above operation procedure or is a user who has not been informed in advance, the function to customize with the display conditions desired by the user is wasted without even knowing that there is a setting screen There are concerns.

  On the other hand, in the non-stop state, it can be considered that the setting screen is displayed and the transition of the setting screen to each setting function is prohibited. However, because the setting screen becomes unresponsive due to the prohibition of transition to each setting function, the cause is due to the non-stop state of the vehicle, or due to an operational error such as insufficient press of the operation switch In some cases, the user does not know whether this is due to a malfunction of a display device such as an operation switch or a display. In this case, there is a risk of giving the user an anxiety that the user is unresponsive or troubled.

  The present invention has been made in consideration of such circumstances, and its purpose is to make it easy to recognize the presence of a setting screen, to ensure the safety of vehicle travel, and to improve the operability for the user. The object is to provide a display device for a vehicle.

  In order to achieve the above object, the present invention comprises the following technical means.

  That is, the invention according to any one of claims 1 to 6 includes a display unit that displays a screen having an information image in a vehicle and a setting operation unit that performs an operation for switching the screen. A setting screen for setting display conditions is set, and the input operation means for performing an input operation by an operation different from the switching operation in the setting operation means, the state of the vehicle is detected, and the vehicle is brought into a stop state based on the detected state. A stop state determination unit that determines whether or not there is an input prohibition unit that prohibits an input operation by the input operation unit and an input operation unit when the stop state determination unit determines that the vehicle is in a non-stop state The operation prohibition screen forming means for forming the operation prohibition screen for displaying the operation prohibition image, and the operation prohibition image by the operation prohibition screen formation means on condition that the input operation is prohibited by Displayed, the display of the operation prohibited image has passed a predetermined display period, characterized in that it and an operation prohibition screen releasing means for returning to the setting screen.

  According to the present invention, the setting screen for setting the display condition of the information image is set by the setting operation means for performing the operation of switching the screen having the information image. The input to the display condition setting function on the set setting screen is performed by an operation different from the switching operation in the setting operation means. Therefore, while switching to a specific screen among a plurality of screens by a normal operation of switching the screen, the setting screen can be displayed as a screen switched to the next of the specific screen. There is a setting screen for setting display conditions for information images, in other words, a setting screen having a function that can be customized by the user's desired display conditions during the switching operation to the screen by the normal operation by such setting operation means. Can be easily recognized by a passenger such as a vehicle driver.

  Further, when it is determined that the vehicle is in a non-stop state, that is, in a traveling state, an input operation to the setting screen by the input operation unit is prohibited and an operation prohibition image is displayed on the screen. According to this, by notifying the user that the operation is prohibited after the setting screen is displayed, the user can easily recognize that the setting screen cannot be input to the setting function. In addition, the display of the operation prohibition image automatically returns to the setting screen when the predetermined display period has elapsed, so “unless the user cancels the operation prohibition screen by manual operation, etc., it is necessary to continue to view unnecessary operation prohibition images after recognition. Users can be freed from the hassle of having to.

  According to the first aspect of the present invention, it is easy for a passenger such as a vehicle driver, who is a user, to recognize the presence of the setting screen, to ensure the safety of vehicle travel, and to improve the operability. Can be obtained.

  The operation different from the switching operation in the setting operation means is, for example, “holding down” for a relatively long time compared to the “short press” in the normal screen switching operation in the setting operation means such as a push switch. Alternatively, the setting operation means for selecting an operation direction such as an operation stick may select either an operation direction different from the operation direction during the normal screen switching operation.

  In the invention according to claim 2, the operation condition by the setting operation means for displaying the operation prohibited image is characterized in that an operation period during which the operation by the setting operation means is valid exceeds a certain time. .

  When the operation period operated by the user whose operation is recognized to be valid by the setting operation means is a time exceeding a certain time, the user may continue to watch the setting screen in order to perform the operation desired by the user.

  On the other hand, according to the second aspect of the present invention, the operation condition for displaying the operation prohibited image is that the operation period for which the operation by the setting operation means is valid is a time exceeding a certain time. By displaying the prohibition image, it is possible to suppress the possibility that the user keeps watching the setting screen.

  In the invention according to claim 3, the operation prohibition screen releasing means validates the operation of the setting operation means within a predetermined display period, and when the effective operation period is within a predetermined time, It changes to the next screen switched from the setting screen.

  According to this, when the input operation by the setting operation means is invalid due to the above condition within the predetermined display period, but the operation of the setting operation means is validated and the effective operation period is recognized to be within a certain time. Then, the transition is made to the next switching screen switched from the setting screen. As a result, even if it takes only a short time within a certain period of time, it will be an effective operation. For users who do not need to customize display conditions by input operations on the setting screen because they have already been set, etc. You can easily get out of the screen. Therefore, the vehicular table device according to the present invention can further improve the operability as compared with the prior art device.

  In the invention according to claim 4, when it is determined by the stop state determination means that the vehicle is in the stop state, the input operation by the input operation means is permitted while the operation by the setting operation means is validated. When the operation period is a time exceeding a certain time, the screen transits to the next screen switched from the setting screen.

  Here, when it is determined by the stop state determination means that the vehicle is in the stop state, the input operation by the input operation means is permitted. Then, after transitioning to the setting function of the setting screen, an unexpected setting function may be given again by an effective operation for a time exceeding a certain time of the setting operation means. In this case, on the transition screen to the setting function of the setting screen, there is a possibility that the user cannot exit the setting screen even though the input of the display condition is completed.

  On the other hand, according to the invention as set forth in claim 4, when the setting operation means gives an effective operation for a time exceeding a certain time as a release condition desired by the user, and when the release condition is satisfied, Since the transition is made from the setting screen to the next switching screen, it is possible to prevent the user from being confused without leaving the setting screen.

  Further, the invention described in claim 5 is characterized in that the operation prohibition screen formed by the operation prohibition screen forming means and the setting screen are displayed in a superimposed manner on the display unit.

  In this invention, when it is determined that the vehicle is in the running state, the input operation to the setting function of the setting screen is prohibited, and the operation prohibited image can be displayed in association with the setting screen. Therefore, it is possible to make the user recognize more effectively that the current situation is in a state where input operation to the setting function of the setting screen is prohibited.

  In the invention according to claim 6, in the setting screen, the setting screen displayed when the stop state determining means determines that the vehicle is in the stopped state, and the stop state determining means makes the vehicle non-stopped. The display content is different from that of the setting screen displayed when it is determined that there is.

  In this invention, when it is determined that the vehicle is in a running state, an operation prohibition display is performed on the operation prohibition screen, and when the operation prohibition has passed a predetermined display period, the setting screen is displayed again. Even when returning to the setting screen, when the vehicle is in the running state, the display content is different from the normal setting screen in which the input operation is permitted.

  Therefore, after the operation prohibition display is given to the user, even if the operation prohibition display is not continued, the user can easily recognize that the current status is the input operation prohibition state to the setting function of the setting screen. Can be made.

  The basic configuration of the vehicle display device 1 has been described above. Hereinafter, a characteristic configuration of the vehicle display device 1 will be described.

(Characteristic configuration)
Each vehicle information displayed on the screen 81 of the display device 8 is operated by the changeover switches 7 and 17 provided around the display device 8. Specifically, by operating the operation switch 7 as the “setting operation means”, the screen is switched to a specific character information image among a plurality of character information images displayed in multiple on the screen 81. Display a specific character information image. Further, the operation of the operation switch 7 makes an input to the display condition setting function on the setting screen which is one of the specific character information images.

  Then, by operating the reset switch 17, when the specific character information image is an odometer or trip meter, the odometer or trip meter is switched or the trip meter is reset. Note that the operation switch 7 may function as the function of the reset switch 17 without being limited to the above configuration.

  Further, in the above configuration, the character information image may be configured such that any one of the character information images other than the odometer and the trip meter is displayed in the lower part of the screen 81.

  Next, from among each character information image displayed in multiple on the screen 81 of the display 8, switching to a specific screen having a specific character information image and operation of a setting screen which is one of the specific screens, This will be described with reference to FIGS.

  As shown in FIG. 4, the character information image displayed on the liquid crystal panel 80 of the display device 8 is that a passenger such as a vehicle driver (hereinafter simply referred to as “user”) operates the operation switch 7 by a predetermined operation method. By doing so, a specific character information image is selected from a plurality of character information images and displayed. Specifically, as the predetermined operation method, for example, seven character information images are sequentially switched and displayed by “short pressing” the switch 7 to operate the switch 7 in a relatively short time.

  As shown in FIG. 4, the seven character information images displayed on the liquid crystal panel 80 are a screen (hereinafter referred to as switching screen 1) for displaying a first character information image related to “outside temperature”, “average vehicle speed”. A screen displaying the second character information image related to (hereinafter referred to as switching screen 2), a screen displaying the third character information image related to "traveling time" (hereinafter referred to as switching screen 3), and a screen related to "travelable distance" A screen for displaying a 4-character information image (hereinafter referred to as switching screen 4), a screen for displaying a fifth character information image relating to “fuel consumption” (hereinafter referred to as switching screen 5), and a specific character information image among the character information images. These are a “setting screen” (hereinafter also referred to as a switching screen 6) for changing the setting of the display conditions, and a screen for displaying a caution image based on, for example, character information (hereinafter referred to as a switching screen 7).

  According to this, since the switching screens 1 to 7 including the setting screen are sequentially switched by “short pressing” the operation switch 7, the switching screen 6 is surely switched to the “setting screen”. As a result, the operation switch 7 is used to switch the switching screens 1 to 7 so that the screen is surely shifted to the “setting screen” for setting the display condition of the character information image. The user can easily recognize that the “setting screen” exists in the operation of sequentially switching to the switching screens 1 to 7 by the normal operation.

  Next, the screen is switched to the “setting screen” as a specific screen among the switching screens 1 to 7, the transition method to the setting function of the “setting screen”, and the normal switching screen 7 from the “setting screen”. A transition method for returning will be described with reference to FIG. FIG. 5 shows the flow of the V range in FIG. 4 and shows the transition process between the switching screen 5 immediately before the “setting screen” and the switching screen 7 next to the “setting screen”. ing. 4 and 5 show control processing obtained by executing a program stored in the memory of the main control unit 90 shown in FIG.

  In S (S is a step) 100, the operation switch 7 is “short pressed” to be switched to the switching screen 5, and the “fuel consumption” state value (for example, 12.3 km / l) is displayed on the screen 81.

  In S <b> 200, it is determined whether or not the normal operation that the operation switch 7 is “short press” is performed according to a user's request. When it is determined that the normal operation of “short press” has been performed, the process proceeds to S300, and is switched to the “setting screen” which is the switching screen 6. When it is determined that the “short press” has not been performed, the display of the switching screen 5 that displays “fuel consumption” is continued.

  When the display is switched to the “setting screen” in S300, it is determined in S400 whether the operation switch 7 is pressed (touched). That is, it is determined whether the operation switch 7 is operated and the operation state is “short press” or “long press”. Here, “long press” means that the switch 7 is kept pressed for a relatively longer time than “short press”.

  If it is determined in S400 that “short press” has been performed after switching to the “setting screen”, the process proceeds to S1000, and the switching screen 7 that is the next switching screen is switched and displayed. In this way, if it is not necessary (for example, it has already been customized), it is possible to input the setting function on the setting screen, such as changing the display condition using the setting function on the setting screen, in other words, customization according to the display condition desired by the user. The operation can be made through a simple [short press] operation for the user.

  On the other hand, when it is determined in S400 that “long press” has been performed, the process proceeds to S500, and it is determined whether or not the vehicle is stopped.

  When it is determined that the vehicle is in the non-stop state, in other words, in the running state, an operation different from the normal operation by the operation switch 7, that is, the “long press” operation is invalidated, and the “setting screen” setting function Prohibit input operation to. Further, the process proceeds to S600, and an operation for displaying an “operation prohibited image” (for example, a warning message “currently setting is prohibited”) indicating a state in which an input operation to the setting function of the “setting screen” is prohibited. Switch to the prohibited screen.

  In S700, it is determined whether or not a predetermined time T has elapsed after switching to the operation prohibition screen in S600. If it is determined that the predetermined time To has elapsed, the display of the operation prohibition screen is stopped and the screen returns to the “setting screen”. When it is determined that the predetermined time To has not elapsed, the “operation prohibited image” is continuously displayed on the operation prohibited screen.

  According to this, when the vehicle is in a stopped state, after displaying the “setting screen”, it is impossible to input to the setting function through the “setting screen” by notifying the user that the operation is prohibited. It can be made easier for the user to recognize. Moreover, the display of the “operation prohibited image” automatically returns to the “setting screen” when a predetermined display period of a certain time To elapses. The user can be freed from the troublesomeness of having to continue to view unnecessary operation prohibited images.

  If it is determined in S500 that the vehicle is in the non-stop state, it is determined that the input operation to the setting function of the “setting screen” is permitted, and the “long press” operation is validated. . Further, the process proceeds to S800, and a transition is made to a “setting function screen” (in this embodiment, a setting function screen I for changing the display condition of the specific character information image) in which the setting function is valid on the “setting screen”. On the setting function screen I, for example, the size of the character display can be changed by selecting three sizes: a size change in the X-axis direction, a size change in the Y-axis direction, and a setting end.

  In S900, it is determined whether the user has performed an input operation according to the change (“Select”) or the setting function screen I is ended (“End”) among the three selection branches. When it is determined that the “selection” work due to the above change has been performed, the setting function screen I is kept waiting and the “selection” work is performed due to another change or the “end” work is performed. In the meantime, input permission of the setting function on the setting function screen I is continued.

  On the other hand, if it is determined that the “end” operation has been performed, the display of the setting function screen I is stopped and the screen returns to the “setting screen”.

  Here, a predetermined time for determining “short press” in the operation period of the operation switch 7 is defined as a certain time Ts. The fixed time Ts may be the same time as the fixed time To or a different time. In other words, when the operation period in which the operation switch 7 is valid is within the predetermined time Ts, “short press” is performed, and when the operation period exceeds the predetermined time Ts, “long press” is performed.

  In the present embodiment described above, the “setting screen” is displayed as one of the switching screens 1 to 7 that are sequentially displayed by the “short press” operation by the operation switch 7. Makes it easier for the passengers to recognize the presence of the “setting screen”. Further, when the vehicle is in the non-stop state, the input to the setting function of the “setting screen” is prohibited, and the “operation prohibition image” is displayed, thereby ensuring the safety of vehicle travel.

  In addition, the display of the operation prohibited image is limited to a predetermined display period and automatically returns to the “setting screen”. Therefore, unless the user disables the operation prohibited screen by manual operation, an unnecessary operation prohibited image after recognition is displayed. Free users from the hassle of having to keep watching. Therefore, the vehicle display device 1 capable of improving display operability can be obtained.

  In the present embodiment described above, the operation condition by the operation switch 7 for displaying the “operation prohibited image” is a time during which the operation period for which the operation switch 7 is valid exceeds a certain time Ts, that is, “long press”. It corresponds to the time.

  The operation period of the operation switch 7 operated by the user on the “setting screen” may be a time exceeding a certain time Ts. In such a case, the user may keep watching the “setting screen” until the setting function of the “setting screen” for performing the operation desired by the user functions normally.

  On the other hand, according to the present embodiment, the operation condition for displaying the “operation prohibited image” is a time exceeding the predetermined time Ts, that is, “long press”, and therefore, the “operation prohibited image” is displayed. Thus, the possibility that the user keeps watching the “setting screen” can be suppressed.

  In the embodiment described above, the setting function screen as the “transition screen” to the setting function in the “setting screen” is described as an example of the setting function screen I. However, the setting function screen is displayed in the “setting screen”. A configuration having a plurality of setting function screens such as a configuration provided for each character information image may be used.

(Second Embodiment)
A second embodiment is shown in FIG. The second embodiment is a modification of the first embodiment. In the second embodiment, an example is shown in which a control process for quickly changing from the “setting screen” to the next switching screen 7 in response to various requests from the user is added. In FIG. 6, the screen transition process on the operation prohibition screen after S600 and the setting function screen I after S800 determined by determining whether or not the vehicle is in a stopped state in S500 is according to the first embodiment. Different from the flow of FIG.

  Here, in the first embodiment, when it is determined that the vehicle is in a non-stop state by determining whether or not the vehicle is in a stop state in S500, a predetermined time corresponding to a predetermined time To in S700. During the display period, the “operation prohibited image” is always displayed.

  On the other hand, in the control process according to the second embodiment, as shown in FIG. 6, when the predetermined time To has not elapsed in S700, the process proceeds to S750, and the operation switch 7 determines to be pressed. In this state, “long press” is invalid, but “short press” is valid. In S750, it is determined that the “short press” operation is an effective press operation. That is, if it is determined in S750 that “short press” has been performed, the process proceeds to S1000, and the switching screen 7 that is the next switching screen is switched and displayed.

  On the other hand, when it is determined in S750 that the “short press” has not been performed or the “long press” operation has been performed, the “operation prohibited image” is continuously displayed on the operation prohibition screen.

  In the present embodiment described above, the display of the “operation prohibited image” is canceled (canceled) by performing the “short press” operation corresponding to the predetermined time Ts within the predetermined display period that is the predetermined time To. be able to. Here, the relationship is To> Ts.

  According to this, as the operation of the operation switch 7, the “long press” operation which is an input operation to the setting function of the “setting screen” is invalid within the predetermined display period, but the normal operation by the “short press” is valid. I have to. Further, when the operation period valid by the operation switch 7 is within the predetermined time Ts, that is, when it is recognized as “short press”, the display of the “operation prohibited image” is stopped and the transition to the next switching screen 7 is made. Like to do. As a result, an effective “short press” operation is possible even for a short time within a certain time Ts, so that it is not necessary to customize display conditions by an input operation to the “setting screen” because it has already been set. The user can easily get out of the “setting screen”. Therefore, the vehicular surface device 1 according to the present invention can further improve the operability as compared with the prior art device.

  Here, in the first embodiment, if it is determined that the vehicle is in a stopped state by determining whether or not the vehicle is in a stopped state in S500, the user is displayed on the setting function screen I in S800. If any one of the above three selection branches is not selected, the input operation by the change has been performed (selection) or the setting end (end) by the setting function screen I is not selected, the determination cannot be made in S900. There is a fear. In the case of a beginner who does not fully understand the setting function or a user who has not been informed in advance, there is a concern that the user cannot get out of the setting function screen I.

  In addition, after changing to the setting function by the setting function screen I among the plurality of setting function screens of the “setting screen”, by performing the “long press” operation again, an unexpected setting other than the “setting function screen I” In some cases, the setting function on the function screen may be given, and in this case, the user can leave the “setting screen” even though the input of the display condition has been completed on any of the setting function screens of the “setting screen”. There is no possibility.

  On the other hand, in the control processing according to the second embodiment, as shown in FIG. 6, when it is determined in S900 that neither “selection” nor “end” is performed, the process proceeds to S950. It is then determined whether or not a “long press” operation has been performed. If it is determined that the “long press” operation has not been performed, it is determined that the user is considering changing the display conditions, and the display of the current setting function screen is continued. On the other hand, when it is determined that the “long press” operation has been performed, the display of the current setting function screen is stopped, the process proceeds to S1000, and the process proceeds to the next switching screen 7.

  According to this, the “long press” operation is given by the operation switch 7 as a release condition for releasing the “setting function” desired by the user, and when this release condition is met, Since the transition to the switching screen 7 is made, it is possible to prevent the user from being confused without leaving the setting function screen in the “setting screen”.

(Other embodiments)
As mentioned above, although one Embodiment of this invention was described, this invention is limited to this embodiment and is not interpreted and can be applied to various embodiment in the range which does not deviate from the summary.

  (1) In the present embodiment described above, an operation different from the switching operation as the “normal operation” with the operation switch 7 as the “setting operation unit” is a normal screen switching operation in the setting operation unit such as a push switch. “Long press” was held for a relatively long time compared to “short press” at the time. However, the present invention is not limited to this, and any operation method such as selecting an operation direction different from the operation direction at the time of a normal screen switching operation by the setting operation means for selecting an operation direction such as an operation stick may be used.

  (2) Further, in the present embodiment described above, the “setting screen” and the “operation prohibited screen having an operation prohibited image” are separately displayed on the display device 8 having the liquid crystal panel 80. However, the present invention is not limited to this, and the “setting screen” and the “operation prohibition screen” may be superimposed and displayed. On the screen 81 of the liquid crystal panel 80, the character information image of the “setting screen” and the operation prohibited image of the “operation prohibited screen” are combined and displayed by driving the constituent pixels of the character information pixel area. Is possible. According to such a configuration, when it is determined that the vehicle is in a running state, an input operation to the setting function of the “setting screen” is prohibited, and the operation prohibited image is associated with the “setting screen”. Can be displayed. Therefore, it is possible to make the user more effectively recognize that the current situation is in a state where input operation to the setting function of the “setting screen” is prohibited.

  (3) Further, in the present embodiment described above, the display method of the character information image on the “setting screen” is the same when the vehicle is in a stopped state and when it is in a non-stopped state. Not limited to this, the “setting screen” displayed when it is determined to be in the stopped state and the “setting screen” displayed when determined to be in the non-stop state are character information images. The display contents may be different. In this case, for example, the character information image of the “setting screen” in the stopped state (hereinafter referred to as a normal setting screen) is displayed in white light emission, and the character information image in the “setting screen” in the non-stop state is displayed in red light emission. To.

  In this invention, when it is determined that the vehicle is in a non-stop state (running state), an “operation prohibited image” is displayed on the operation prohibition screen, and when the “operation prohibition image” has passed a predetermined display period, The screen will return to the “setting screen”. When the vehicle is in a non-stop state (running state) even when returning to such a “setting screen”, the “normal setting” is permitted. The display content is different from the “screen”.

  Therefore, after the “operation prohibited image” is displayed to the user, even if the “operation prohibited image” display is not continued, the current situation is “the input operation to the setting function of the setting screen is prohibited”. This can be easily noticed by the user.

  (4) In the present embodiment described above, the information image displayed on the display device 8 is a character information image. However, the present invention is not limited to this, and symbols such as characters, pictograms, designs, and symbols are combined. It may be a thing.

  (5) In the present embodiment described above, the display device 8 is described using a TFT transmissive liquid crystal panel. The display 8 is not limited to this, and may be any of liquid crystal panels such as TFT, STN, DSTN, and ASTN, and display elements such as VFD and EL.

  (6) Further, in the present embodiment described above, it has been described that only the display device 8 performs multiple display in the vehicle display device 1, but the present invention is not limited to this, and a tachometer, a speedometer, a fuel meter, an indicator light, etc. Multiple display may be used. In this case, on the liquid crystal panel screen, a tachometer pixel area for displaying a tachometer, a speedometer pixel area for displaying a speedometer, a fuel gauge pixel area for displaying a fuel gauge, and a display lamp pixel for displaying a display lamp Provide an area.
