  However, the display methods shown in FIGS. 25 to 26 have the following problems. That is, in the display of the display device shown in FIG. 25, it appears that the state A can be switched to the state C if the select lever is swung to the right from the position of the state A. Similarly, in the display of the display device shown in FIG. 26, it appears that the state B can be switched to the state C if the select lever is swung to the right from the position of the state B. However, as is apparent from the actual positional relationship of the shift positions shown in FIG. 24, the select lever cannot be swung to the right from either state A or state B. That is, the display method shown in FIGS. 25 to 26 cannot accurately display the path for swinging the select lever.

FIG. 27 is a diagram showing a display method for erasing the display of the state C displayed at the display position 903 in consideration of the problems of the display methods shown in FIGS. 25 to 26 described above. However, in the display method shown in FIG. 27, the path for swinging the select lever from the state A or the state B to the position of the state C is not displayed. That is, in the display method shown in FIG. 27, the path for swinging the select lever cannot be accurately displayed, as in the display methods shown in FIGS.

In the first embodiment, the case where both the first position 123 and the second position 124 are substantially in the center of the display screen of the display device 12 will be described as an example. Note that the first position described in the claims does not necessarily correspond to the first position in all the embodiments of the present invention, and is a predetermined position predetermined on the display screen of the display device. It should be noted that The same applies to the second position and the third position described in the claims.

  FIG. 5 is a diagram illustrating an example of the shift position display displayed on the display device 12 by the display control device 10 according to the first embodiment. As will be described later, the display device 12 displays a speedometer and the like together with the shift position, but FIG. 5 shows only the shift position.

  The display control device 10 indicates the guide image 121 arranged so that any one of the shift lever holding signs 122a to 122e corresponding to the shift position indicated by the shift position information is drawn at the first position 123 and the shift position information. The shift position indicator 125 corresponding to the shift position is combined with the shift position image 125 that is drawn at the second position 124, and the combined image is output to the display device 12, thereby realizing the display shown in FIG.

The display control apparatus 10 includes a switching determination unit 101, a shift position image storage unit 102, a guide image storage unit 103, an image specifying unit 104, a guide image processing unit 105, and an image composition unit 106.

  The switching determination unit 101 determines whether or not the shift position has been switched by the occupant based on the shift position indicated by the shift position information output from the transmission 11. Then, the switching determination unit 101 outputs the shift position information output from the transmission 11 only when the shift position is switched.

  The shift position image storage unit 102 stores as many shift position images 125 as the number of shift positions of the transmission 11 in which shift position indicators each indicating the shift position of the transmission 11 are drawn at the second position 124. .

  The guide image storage unit 103 stores a guide image 121 shown in FIG.

  The image specifying unit 104 reads out the shift position image 125 corresponding to the shift position indicated by the shift position information input from the switching determination unit 101 from the shift position image storage unit 102 and outputs it.

  The guide image processing unit 105 reads the guide image 121 stored in the guide image storage unit 103 from the guide image storage unit 103. Then, the guide image processing unit 105 draws one of the shift lever holding signs 122a to 122e corresponding to the shift position indicated by the shift position information output from the switching determination unit 101 at the first position 123. Then, the read guide image 121 is moved and arranged.

  The image synthesizing unit 106 synthesizes the shift position image 125 output from the image specifying unit 104 and the guide image 121 output from the guide image processing unit 105 and outputs the synthesized image to the display device 12.

  Next, specific processing of the display control apparatus 10 configured as described above will be described with reference to the flowchart shown in FIG.

  In step S <b> 101, the switching determination unit 101 determines whether or not the shift position has been switched by the passenger based on the shift position information input from the transmission 11. When the switching determination unit 101 determines that the shift position has been switched, the process proceeds to step S102. When the switching determination unit 101 determines that the shift position has not been switched, the process of step S101 is repeated.

  Details of timing at which the switching determination unit 101 determines that the shift position has been switched will be described. An example of a switch that detects the shift position of the shift lever 112 is an inhibitor switch. The inhibitor switch has a plurality of electrical contacts, and detects the shift position of the shift lever 112 by a combination of On and Off of these contacts. In some cases, these contact points are arranged at a predetermined interval. Therefore, the shift position information input to the switching determination unit 101 when the shift position is switched indicates the shift position after switching from the state indicating the shift position before switching to the state where no shift position is indicated. It becomes a state. In such a case, the switching determination unit 101 determines that the shift position has been switched when the shift position information indicates a shift position after switching through a state in which no shift position is indicated.

  In step S102, the image specifying unit 104 reads out the shift position image 125 corresponding to the shift position indicated by the shift position information output from the switching determination unit 101 from the shift position image storage unit 102, and outputs it. When the image specifying unit 104 completes the process of step S102, the process proceeds to the process of step S103.

  In step S <b> 103, the guide image processing unit 105 reads the guide image 121 from the guide image storage unit 103. When the guide image processing unit 105 completes the process of step S103, the process proceeds to the process of step S104.

  In step S <b> 104, the guide image processing unit 105 reads the guide image read so that the shift lever holding sign corresponding to the shift position indicated by the shift position information output from the switching determination unit 101 is drawn at the first position 123. 121 is arranged. When the guide image processing unit 105 completes the process of step S104, the process proceeds to step S105.

In step S <b> 105, the image composition unit 106 synthesizes the shift position image 125 output from the image specifying unit 104 and the guide image 121 output from the guide image processing unit 105 and outputs the combined image to the display device 12. When the image composition unit 106 completes the process of step S105, the display control apparatus 10 repeats the process shown in the flowchart of FIG. 6 from step S101.

  7A to 7E are diagrams showing the shift position display of the display device 12 when the shift lever is switched to each of the shift lever holding positions 114a to 114e. In the display control device 10 according to the first embodiment, the first position 123 and the second position 124 are substantially the center of the display screen of the display device 12 and are the same position as each other. Accordingly, the display control device 10 determines whether the shift lever is switched to any shift lever holding position, the shift lever holding sign corresponding to the current shift position on the guide image 121 and the shift position image corresponding to the current shift position. 125 is always displayed at substantially the center of the display screen of the display device 12.

  FIG. 8 is a schematic diagram showing an example of the display device 12 according to the present invention. As described above, the display device 12 displays a speedometer and the like together with the shift position. However, the shift position display displayed by the display control device 10 according to the first embodiment does not necessarily have to be displayed on the display device 12 together with the speedometer or the like, and only the shift position display is displayed on the TFT liquid crystal display device or the like. May be. In addition, the display device 12 may be a display device including a speedometer as a general instrument panel that has been used in the past and a display unit that displays only the shift position. A display device that displays the image on a liquid crystal display device or the like may be used.

  Some automatic transmissions in recent years can select a sequential shiftmatic mode in which the transmission gears can be manually switched. The present invention is also effective for displaying a shift position and a shift stage of a transmission equipped with a sequential shiftmatic mode. FIG. 9 shows a configuration of a display control device 10a in which new components are added to the above-described display control device 10 in order to display a shift position and a gear position when the transmission 11 is equipped with the sequential shiftmatic mode. FIG. The difference between the display control device 10a and the display control device 10 is that the switching determination unit 107 and the image specification unit 109 that operate differently from the switching determination unit 101 and the image specification unit 104, respectively, and the display control device 10 are not provided. And a gear position image storage unit 108.

  FIG. 10 is a diagram illustrating an example of a shift speed displayed on the display device 12 by the display control device 10a. When the shift position is the S position, the display control device 10a includes the guide image 121 and the gear position that are arranged so that the shift lever holding mark 122e corresponding to the shift position of the S position is drawn at the first position 123. An image obtained by combining the shift speed image 126 in which the shift speed number indicated by the information is drawn at the second position 124 is displayed.

  Next, a more specific configuration of the display control apparatus 10a for realizing the display as shown in FIG. 10 will be described with reference to FIG. 9 again. In the display control device 10a, the same components as those of the display control device 10 are denoted by the same reference numerals, and description thereof is omitted.

  Based on the shift position indicated by the shift position information output from the transmission 11 and the gear position indicated by the gear position information, the switching determination unit 107 determines whether the shift position or the gear position has been changed by the occupant. The switching determination unit 107 outputs the shift position information and the gear position information output from the transmission 11 only when the shift position or the gear position is switched by the passenger.

The shift speed image storage unit 108 stores a plurality of shift speed images 126 in which numbers indicating shift speeds that can be selected in the sequential shiftmatic mode are respectively drawn at the second position 124. FIG. 11 shows the shift speed image 12 stored in the shift speed image storage unit 108.
As an example of FIG. 6, a number indicating that the current shift speed is the third speed indicates the shift speed image 126 drawn at the second position 124.

  The image specifying unit 109 reads out the shift position image 125 corresponding to the shift position indicated by the shift position information output from the switching determination unit 107 from the shift position image storage unit 102 and outputs it. In addition, when the shift position indicated by the shift position information is the S position, the image specifying unit 109 displays the shift stage image 126 corresponding to the shift stage indicated by the shift stage information output from the switching determination unit 107. Read from 108 and output.

  Then, the image composition unit 106 synthesizes and outputs the guide image 121 arranged by the guide image processing unit 105 and the gear stage image 126 output from the image specifying unit 109. That is, as an example, when the image composition unit 106 displays the third gear position when the shift position is the S position, it corresponds to the gear position image 126 shown in FIG. 11 and the S position shift position shown in FIG. 10 is combined with the guide image 121 arranged so that the shift lever holding sign 122e to be drawn at the first position 123 is displayed.

  Next, specific processing of the display control apparatus 10a configured as described above will be described with reference to the flowchart shown in FIG. Of the processes shown in the flowchart of FIG. 13, the same processes as those shown in the flowchart of FIG. 6 are denoted by the same reference numerals and description thereof is omitted.

  In step S201, the image specifying unit 109 determines whether or not the shift position indicated by the shift position information output from the switching determination unit 107 is the S position. When the image specifying unit 109 determines that the shift position indicated by the shift position information is the S position, the process proceeds to step S202. When the image specifying unit 109 determines that the shift position indicated by the shift position information is not the S position, the process proceeds to step S102.

  In step S202, the image specifying unit 109 reads out and outputs the gear stage image 126 corresponding to the gear stage indicated by the gear stage information output from the switching determination unit 107 from the gear stage image storage unit 108. When the image specifying unit 109 completes the process of step S202, the process proceeds to the process of step S103.

  In step S <b> 203, the switching determination unit 107 determines whether or not the shift speed has been switched by the passenger based on the shift speed information output from the transmission 11. When the switching determination unit 107 determines that the gear position has been switched, the process proceeds to step S202. When the switching determination unit 107 determines that the gear position has not been switched, the process returns to step S201. Note that details of the timing at which the switching determination unit 107 determines that the gear position has been switched are the same as those of the switching determination unit 107 according to the first embodiment, and a description thereof will be omitted.

  14A to 14E are diagrams illustrating display by the display control device 10a when the transmission gear 11 is switched to each gear position in the sequential shiftmatic mode. In the display control device 10a, the first position 123 and the second position 124 are substantially the center of the display screen of the display device 12, and are the same position as each other. Therefore, the display control device 10a, regardless of which side the gear position of the transmission 11 is switched to, is immediately shifted to the shift lever holding mark 122e corresponding to the shift position of the S position and the gear position image 126 corresponding to the current gear position. Are always displayed in the approximate center of the display screen of the display device 12.

As described above, according to the display control apparatus 10 according to the first embodiment, since the guide image 121 simulating the guide 113 is displayed on the display device, the passenger visually recognizes the guide image 121 displayed on the display device. Therefore, the direction in which the shift lever is swung can be confirmed without checking the hand. In addition, since the shift position image 125 indicating the current shift position is always fixed and displayed at substantially the center of the display screen of the display device 12, the occupant does not move the line of sight and moves the current shift position and the shift lever. The moving direction can be confirmed at the same time. Therefore, according to the display control apparatus 10 according to the first embodiment, the passenger can obtain a display that makes it easy to understand the swing direction and shift position of the shift lever.

  Further, according to the display control apparatus 10a, the shift lever holding mark 122e corresponding to the S position is arranged so that the guide image 121 and the gear position indicated by the gear position information are displayed so as to be drawn at the first position 123. The gear position image 126 arranged at the second position 124 can be displayed. Since the display control device 10 does not include the gear position image storage unit 108, the character displayed at the second position 124 is not changed even when the shift position is switched to the S position or when the gear position is switched. The character “S” indicated by the shift position information and the speed indicated by the speed information, that is, the number cannot be displayed. However, according to the display control device 10a, when the shift position is switched to the S position, the gear position indicated by the gear position information, that is, a number is displayed on the display screen of the display device 12 at the second position 124. . For this reason, the passenger can directly know the gear position when the shift position is the S position.

  In the first embodiment, the first position 123 and the second position 124, that is, the position where the character of the shift position is displayed and the position where the shift lever holding sign corresponding to the shift position is displayed are the same. The case of the position has been described as an example. However, the first position 123 and the second position 124 are not necessarily the same position. Even if the first position 123 and the second position 124 are different from each other on the display screen of the display device 12. Good.

  In the first embodiment, the image synthesis unit 106 synthesizes the shift position image 125 and the guide image 121 and outputs the synthesized image as it is. However, as shown in FIG. 15, when the first position 123 and the second position 124 are different from each other, the image composition unit 106 further shifts the composite image corresponding to the current shift position. At a first position 123 where the lever holding sign is displayed, a shift position sign 127 (FIG. 15) having a display mode different from that of the shift lever holding sign other than the current shift position (in the example of FIG. 15, a black circle). In the example, a white circle) may be superimposed and combined. The image composition unit 106 superimposes the shift position indicator 127 on the first position 123 so that the shift lever holding indicator corresponding to the shift position indicated by the shift position information is different from other shift lever holding indicators. Since it is displayed, it is possible to make it easier for the passenger to understand the shift position on the guide image 121.

  In the first embodiment, when the first position 123 and the second position 124 are the same position, depending on the type of guide shape of the guide image 121 or the size of the shift position indicator, In some cases, the shift position indicator displayed on the display screen is overlapped with one of the shift lever holding indicators other than the shift lever holding indicator corresponding to the current shift position. In this case, the guide image processing unit 105 may output a processed image by performing a process of moving the display position of the shift lever holding sign that is displayed so as to overlap with a position that does not overlap the shift position sign. As a result, the shift position sign drawn on the shift position image 125 and the shift lever holding sign drawn on the guide image 121 do not overlap each other on the display screen of the display device 12. It is possible to prevent the visibility with the guide image 121 from being deteriorated.

(First modification of the first embodiment)
It should be noted that the display control device 10a may display a shift direction image as shown in FIGS. 16A and 16B on the display device 12 when the shift speed is switched to the high speed stage or the low speed stage in the sequential shiftmatic mode. Good. FIG. 17 is a modification of the flowchart of FIG. 13 in order for the display control device 10a to display a shift direction image when the gear position is switched. Therefore, in the flowchart of FIG. 17, the same steps as those of FIG.

  First, in step S203, the switching determination unit 107 determines whether or not the gear position has been switched by the occupant based on the gear position information output from the transmission 11. When the switching determination unit 107 determines that the gear position has been switched, the process proceeds to step S2001. When the switching determination unit 107 determines that the gear position has not been switched, the process returns to step S201.

  In step S2001, the image specifying unit 109 reads out and outputs the gear stage image 126 corresponding to the gear stage indicated by the gear stage information output from the switching determination unit 107 from the gear stage image storage unit 108. When the image specifying unit 109 completes the process of step S2001, the process proceeds to the process of step S2002.

  In step S2002, the image specifying unit 109 determines whether a shift-up operation or a shift-down operation has been performed based on the shift speed information output from the switching determination unit 107. When the image specifying unit 109 determines that a downshift operation has been performed, the process proceeds to step S2003. On the other hand, when the image specifying unit 109 determines that a shift-up operation has been performed, the process proceeds to step S2004.

  In step S2003, the image specifying unit 109 displays the shift direction image on which the sign “−” indicating that the downshift operation has been performed at the predetermined position 131 on the display screen of the display device 12 is drawn. Read from and output. When the image specifying unit 109 completes the process of step S2003, the process proceeds to the process of step S2005. FIG. 16A is a diagram illustrating the shift direction image read by the image specifying unit 109 in step S2003. Note that the guide image 121 indicated by a broken line in FIG. 16A is shown in order to clarify the positional relationship between the sign “−” on the display screen of the display device 12 and the guide image 121. The image output from the unit 109 is not included.

  In step S2004, the image specifying unit 109 displays the shift direction image on which the “+” mark indicating that the shift-up operation has been performed at the predetermined position 132 on the display screen of the display device 12 is drawn. Read from and output. When the image specifying unit 109 completes the process of step S2004, the process proceeds to step S2005. FIG. 16B is a diagram showing the shift direction image read by the image specifying unit 109 in step S2004. Note that the guide image 121 indicated by a broken line in FIG. 16B is shown in order to clarify the positional relationship between the “+” sign on the display screen of the display device 12 and the guide image 121. It is not included in the image output from the unit 109.

  In step S2005, the image composition unit 106 synthesizes and outputs each of the guide image 121 output from the guide image processing unit 105, the shift stage image 126 output from the image specifying unit 109, and the shift direction image.

As described above, according to the first modification of the first embodiment, the image specifying unit 109 outputs a shift direction image in which a “-” sign is drawn when a downshift operation is performed, and the upshift is performed. When the operation is performed, a shift direction image in which a “+” sign is drawn is output. And since the image composition unit 106 outputs an image in which one of the shift direction images of “+” or “−” is synthesized, the passenger does not compare the shift stage before and after switching the shift stage. It is possible to instantly confirm that a downshift operation or an upshift operation has been performed.

  In the first modification of the first embodiment, during the period in which the image specifying unit 109 outputs the shift direction image in which either “+” or “−” is drawn, the passenger shifts. It may be only a period during which it can be confirmed that the down operation or the upshift operation has been performed. Specifically, a sign “+” or “−” is displayed for a predetermined time after either the downshift operation or the upshift operation. This prevents the passenger from being confused by continuing to display either the “+” or “−” sign on the display device 12 despite the completion of the downshift or upshift operation. Because.

Move by the amount. When the guide image processing unit 105 completes the process of step S1001, the process proceeds to the process of step S105.

  In step S1002, the guide image processing unit 105 determines whether or not a shift lever holding sign corresponding to the shift position indicated by the shift position information is arranged at the first position 123 in the guide image 121 moved in step S1001. to decide. When the guide image processing unit 105 determines that the shift lever holding sign corresponding to the shift position indicated by the shift position information is arranged at the first position 123, the process shown in the flowchart of FIG. 18 is repeated from step S101. . On the other hand, when the guide image processing unit 105 determines that the shift lever holding sign corresponding to the shift position indicated by the shift position information on the guide image 121 is not disposed at the first position 123, the process proceeds to step S1001. Return.
