Figure 12 is a process flow diagram, and it has illustrated the processed content in the CPU1021 of indicative control unit 1002.For example, if when the driver opens ignition switch, said processing begins.At step a1, the content of the installation position data that affirmation is stored in the EPROM of storer 1005.When said installation position data was the steering wheel position data of expression bearing circle in the left side, CPU1021 was at step a2 control vehicle left image just in motion, and said image is regarded as being used for the image of operating seat.

Further, when said installation position data was the steering wheel position data of expression bearing circle on the right side, CPU1021 controlled vehicle said right image just in motion in step a3, and with said image as the image that is used for operating seat.

Further; When said installation position data be the expression be installed on the said vehicle display device (accurately; When display unit 1001) being installed in data on the back seat; CPU1021 does not control vehicle left image and right image just in motion at step a4, and said image is not regarded as being used for the image of operating seat.That is, even go detecting vehicle, and, when the controlled image of said demonstration is displayed on left side and right side and perhaps is displayed on any side, still can continue to show said image.

Figure 13 is a process flow diagram, and it has illustrated the processed content when by the CPU1021 display image.When showing said image, carry out this processing for operating seat.That is, in the step a2 or a3 of Figure 12, when vehicle ', control said left image or right image, and with it as the image that is used for operating seat; That is, on display unit 1001, show the image that is used for operating seat.

In step b1, judge whether that based on sensor signal vehicle goes from vehicle speed sensor 1004.Go if judge said vehicle, then flow process proceeds to step b2, judges therein whether the image that is used for operating seat is the controlled image of said demonstration.If judging the image that is used for operating seat is to show controlled image, then flow process proceeds to step b3, shows that therein the said image that allows to be shown is as the image that is used for operating seat.

The said image that allows to be shown is the image that the driver can not watch attentively, such as, rest image or can predict the dynamic image of its variation to a certain extent.For example, the said image that allows to be shown is like hypograph.

As predetermined rest image; Can use the initial screen of audio player, only have blue so-called blue background screen, through for example stopping the black screen that black is only arranged that output realized of image, perhaps used before detecting vehicle ' the image of catching of dynamic images displayed.Owing to can predict the variation of said dynamic image to a certain extent, further, can use the screen of the guider 1031 that shows the vehicle location when going and such as the dynamic image of the simple repetition of the screen protection of personal computer.

If judge that at step b1 said vehicle is not going, if judge that perhaps the image that is used for operating seat is not with controlled image, flow process proceeds to step b4, to continue to show the current state of said image.

(1) according to the foregoing description; The said installation position data of storage in the EPROM of storer 1005; And judge whether when vehicle ', to be controlled at the right image and the left image that show on the display unit 1001; That is, judge based on the installation position data of being stored whether said image is the image that is used for operating seat.Can depend on that like this position that display unit 1001 is installed suitably controls the image that is used for operating seat.For example, when said steering wheel position data are stored as installation position data,, and it is regarded as being used for the image of operating seat if bearing circle on the right side, is then controlled said right image when vehicle '.When bearing circle during, when vehicle ', control said left image, and it is regarded as being used for the image of operating seat in the left side.Thereby, when vehicle ', suitably control the said image that is used for operating seat.Further, when said installation position data is expression when display unit 1001 is installed in the data on the back seat, right image and left image are not controlled, and thought that said image is not used for operating seat.Therefore, even work as vehicle just in motion, the image that is shown is not controlled said yet.Through with reference to above-mentioned installation position data, can depend on that the location-appropriate ground control that display unit 1001 is installed is used for the demonstration of the image of operating seat.

(2) according to the foregoing description; When detecting that vehicle is going and display unit 1001 is showing that controlled image is when being used for the image of operating seat; On display unit 1001, show the said images displayed that is allowed to, as the image that is used for operating seat.This can prevent that the driver from watching the image that is used for operating seat attentively, and has realized that the image of considering the security when vehicle ' shows.

Can change the foregoing description with the mode that is described below.

(3) driver can select the image that is shown from multiple permission images displayed, as the image that is used for operating seat when the vehicle '.Select said image through utilizing user as image-selecting device that input block 1006 is set.In this case, when detecting vehicle just in motion, show the said permission images displayed of selecting by the driver, as the image that is used for operating seat.Therefore, can when vehicle ', the above-mentioned image that is used for operating seat be used as the said permission images displayed that has satisfied driver's hobby, rather than show said controlled image.

(4) when detecting that vehicle is going and the image that is used for input operation just is being reserved as the image of operating seat when showing; The image that said permission images displayed can be reserved as operating seat shows, and the image that the said image that is used for input operation can be reserved as the front passenger position shows.In this case; If the driver is at starting vehicle when making the image be used for input operation be shown as the image that is used for operating seat to carry out said input operation; Then said permission images displayed is shown as the image that is used for operating seat, and the said image that is used for input operation is shown as the image that is used for the front passenger position.Therefore, under the situation of the input operation of having interrupted the driver owing to the starting of vehicle, can carry out follow-up input operation by the passenger on the front passenger position.So, can not interrupt said input operation, and can be reliably and intactly carry out said input operation.

(5) when detecting that vehicle is going and the image that is used for input operation just is being reserved as the image of operating seat when showing; Can executivecontrol function; The image that will be used for input operation shows as the image that is used for the front passenger position; Be used for the image of all input operations with covering, perhaps cover the image that is used for specific input operation.For example; Can show the image be used to require such as the input operation of the complex operations of roll operation for the front passenger position; And not forward passenger-seat show the image of the input operation be used for the requirement simple operations, this simple operations is such as only pressing switch once with regard to achievable input operation.

(6) can based on; For example; Parking brake signal (PKB signal) is closed, and by the motion of GPS (GPS) input to vehicle, perhaps the fact that vehicle is going is judged in detected vibration owing to integrated gyrostatic testing result in guider 1031.

(7) when detecting vehicle just in motion; Not only when said controlled image is shown as the image that is used for operating seat; Executivecontrol function; Said permission images displayed is shown as the image that is used for operating seat, and said control operation has nothing to do with showing the said state that is used for the image of operating seat.For example, when detecting that vehicle is going and during for the operating seat images displayed, can showing said permission images displayed.Further, when detecting vehicle is going and said permission images displayed is reserved as operating seat image and show, can the image switching that be shown be allowed images displayed to another with said.

(8) when detecting vehicle just in motion; Not only when the image that will be used for input operation shows as the image that is used for operating seat; Executivecontrol function; The image that will be used for input operation shows as the image that is used for the front passenger position, and said control operation has nothing to do with showing the said state that is used for the image of operating seat.For example; When not shown controlled image or permission images displayed, can the image that be used for input operation be shown as the image that is used for the front passenger position for the operating seat images displayed or for operating seat when detecting that vehicle is going.

(9) although illustrated the foregoing description for the situation of mount display in vehicle, said display device is not limited to be used in the inside of vehicle car, also can be installed in all places.

Figure 15 and 16 has illustrated the example that controlled screen switches when going.In Figure 15 and 16; Diagrammatic sketch (a) has been illustrated when the operating seat example that the screen when (be called right-hand to dish vehicle) switches on the vehicle body right side, and diagrammatic sketch (b) has been illustrated the example when the screen switching of operating seat during in vehicle body left side (being called left-hand control car).

Example shown in Figure 15 is the situation that the vehicle that stops has begun to go and said image is controlled; And in this case; Said screen is switched to the permission images displayed of having chosen before at controlled image (for example, DVD image) (for example, navigation picture).That is, when vehicle just stops (1), show navigator image on the screen 1050 of operating seat side, and on the screen 1060 of front passenger position side, show the DVD image.After this (when vehicle just stops (2)), through on screen 1050, showing the DVD image, the driver can appreciate and watch said image.At this; If now the vehicle begin column is sailed (vehicle goes (3)) and through the said display device of control of going; Then will automatically switch to navigation picture as the DVD image with controlled image, wherein said navigation picture is the permission images displayed of before the screen of having controlled the operating seat side through going 1050, just having selected.In this case, do not control the image of front passenger position side through going, it remains the DVD image.At diagrammatic sketch (a) with (b), exchange operating seat and front passenger position, and exchange right image and left image.Yet said step is with identical by controlling toggle screen through going.

Example shown in Figure 16 is a situation about controlling through going, forbid showing in the operating seat side that will control by going said with controlled image (that is, the DVD image), and through on static screen, insert character, image waits and informs this fact.Promptly; If in that said vehicle begins to go under the state that shows said DVD image on the screen of operating seat side because vehicle just stops (2); Then interrupt on the screen 1050 of operating seat side demonstration by the strong hand to the DVD image; And, for example, " show controlled through inserting character statement.Please only appreciate sound " said screen is switched to static screen by the strong hand.On the other hand, do not control front passenger position side, continue to show DVD image as with controlled image through going.Therefore, when vehicle just in motion, stop the demonstration with controlled image of operating seat side automatically, and make the driver be absorbed in safe driving, make passenger on the front passenger position freely appreciate simultaneously and watch image.

Figure 17 is a diagrammatic sketch, and it has illustrated an alternative embodiment of the invention, and is the process flow diagram that is used to change the object that will control through going.Promptly; Said process flow diagram is used to depend on that the bearing circle of the vehicle that said display device has been installed still is that said installation position data (operator's seat bit data) is come suitably to import in the left side on the right side; Be used for the image of controlling through going suitably is set, and be used to make it possible to be chosen in images displayed on two screens.This structure makes to have bought display device of the present invention and prepared and personally its user who is installed on the vehicle can be provided with said screen arbitrarily, wherein, will depend on that said screen is controlled in the position of the bearing circle of the vehicle that said user has through going.If do not have this structure, with the inconvenience that occurs being described below.Promptly; Bought the user of the vehicle in left side and be set to control and designed to be used the display device of bearing circle if having bearing circle in the common vehicle on right side through going, then, when starting two Presentation Function; The screen on right side (front passenger position side) is controlled; Although in fact it does not need Be Controlled, that is, suitably do not carry out the control of carrying out through going.

The structure of the process flow diagram shown in Figure 17 is described referring now to the screen that is used for initial setting up of Figure 18.The condition that begins said initial setting up is that the display device that is integrated in the vehicle is connected to battery and is unlocked (ignition switch unlatching).If said condition is satisfied and the sub-process that is used for said initial setting up begins, then display device step c1 with do not carry out said two the demonstration (screen is closed in two demonstrations, such as on the right screen with left screen on the identical image of demonstration) the pattern display screen.In next procedure c2, judge whether said user operated with carry out said two the demonstration (as, in the time longer, press said pair of display button than predetermined amount of time).
