Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same members are denoted by the same reference numerals, and redundant descriptions are omitted. (First Embodiment) FIG. 1 is an external view of a vehicle 1 which is an example of a moving body equipped with the display system according to the present embodiment and capable of moving while holding the display system. The vehicle 1 is driven and operated by a driver 50. In the following description, the forward direction of the vehicle 1 is the +Z direction, the rearward direction is the -Z direction, the leftward direction is the +X direction, the rightward direction is the -X direction, the upward direction is the +Y direction, and the downward direction is the -Y direction.

[0010] On the front right corner of the vehicle 1, a front right direction indicator 2A and a right front headlight 3A are arranged. On the front left corner of the vehicle 1, a front left direction indicator 2B and a left front headlight 3B are arranged. The front right direction indicator 2A and the front left direction indicator 2B are direction indicators that indicate the direction in which the vehicle 1 is moving to the surroundings by their blinking. The right front headlight 3A and the left front headlight 3B are headlamps that illuminate the front of the vehicle 1. In the center of the front of the vehicle 1, a bumper 4 for reducing the impact and vibration during a collision of the vehicle 1, and a front license plate 5A used for identifying the vehicle 1 are arranged.

[0011] The vehicle 1 has a display unit 6 for displaying the content in order to convey the action intended by the driver 50 to the surroundings. The object to which the driver 50 wishes to convey the intended action, including vehicles such as pedestrians and oncoming vehicles, will hereinafter be referred to as the display object.

[0012] The display unit 6 is disposed below the front right direction indicator 2A, the front left direction indicator 2B, the right headlight 3A, and the left headlight 3B, and above the bumper 4, so as not to protrude forward of the vehicle 1 beyond the bumper 4. Further, the display unit 6 is arranged such that the display surface 6A is formed as a curved surface with a convex center portion facing forward, and covers most of the front portion of the vehicle 1. By providing such a curved surface and the display surface 6A having a large number of display areas, the display target can recognize the display surface 6A in a wide range located in the front portion of the vehicle 1. In the present embodiment, the right end portion of the display unit 6 is referred to as the right end 6R, and the left end portion is referred to as the left end 6L.

[0013] FIG. 2 is a diagram schematically showing the interior of the vehicle 1, and shows a state in which the driver 50 is driving. In the vehicle interior, a driver imaging device 70 is provided as an imaging device for detecting the line of sight of the driver 50. The driver 50 operates the vehicle 1 using a steering wheel 80 for determining the traveling direction of the vehicle 1, and an accelerator and a brake (not shown) for operating the acceleration and deceleration of the vehicle 1.

[0014] FIG. 3 is a diagram schematically showing the periphery of the steering wheel 80. Around the steering wheel 80, a direction indicator operation member 81 that the driver 50 operates when blinking the aforementioned direction indicator is provided. By blinking the direction indicator according to the operation direction of the direction indicator operation member 81, the moving direction of the vehicle 1 can be indicated to the surroundings. Around the steering wheel 80, a plurality of display buttons 82 including a display button 82A that are operated when displaying information on the display unit 6 are provided. Various display contents to be displayed on the display unit 6 are assigned to each of the plurality of display buttons 82. When the driver 50 wants to convey a predetermined intention to the outside of the vehicle 1, the driver 50 can display the intention on the display unit 6 by operating the display button 82 to which the content to be conveyed is assigned. In the present embodiment, when the display button 82 is pressed once, the display unit 6 enters the display state, and when the same button is pressed again, the display unit 6 enters the non-display state.

[0015] FIG. 4 is a block diagram of the display system control unit 100 of the present embodiment. The display system control unit 100 includes a display button input detection unit 101, a gaze recognition unit (acquisition unit) 102, a display area setting unit (setting unit) 103, a display control unit 104, and a storage unit 105. The display button input detection unit 101 detects an operation (input) on any one of a plurality of display buttons 82 of the driver 50. The gaze recognition unit 102 recognizes (acquires) the gaze direction of the driver 50 based on an image captured by the driver imaging device 70 directed at the driver 50. The display area setting unit 103 sets a display area for display on the display surface 6A based on the gaze direction of the driver 50 recognized by the gaze recognition unit 102. The storage unit 105 stores the display content assigned to each of the plurality of display buttons 82. The display control unit 104 displays the display content assigned to the display button 82 on which an operation is detected by the display button input detection unit 101 in the display area set by the display area setting unit 103. In the present embodiment, two display contents (first display content and second display content) are provided and assigned, and when a display button 82 to which two display contents are assigned is operated, the two display contents stored in the storage unit 105 are displayed simultaneously. In the present embodiment, it is assumed that two display contents are assigned to the display button 82A.

[0016] FIG. 5 is a flowchart showing a method for setting the display area. In step S501, the gaze recognition unit 102 recognizes (acquires) the gaze direction of the driver 50 based on an image captured by the driver imaging device 70. In step S502, the display area setting unit 103 sets the display area of the first display content on the display surface 6A using the gaze direction of the driver 50 recognized by the gaze recognition unit 102. In step S503, the display area setting unit 103 sets the display area of the second display content on the display surface 6A using the gaze direction of the driver 50 recognized by the gaze recognition unit 102. When a display button to which one display content is assigned is operated, only the first display content 60 is set.

[0017] FIG. 6 is a flowchart regarding the execution and cancellation of the display on the display unit 6. In step S601, the display control unit 104 determines whether an operation on the display button 82A is detected by the display button input detection unit 101. If the display control unit 104 determines that an operation on the display button 82A is detected by the display button input detection unit 101, it executes the process of step S602. If it determines otherwise, it executes the process of this step again. In step S602, the display area setting unit 103 sets the display area. In step S603, the display control unit 104 performs a display in the display area set in step S602. In step S604, the display control unit 104 determines whether an operation on the display button 82A is detected by the display button input detection unit 101. If the display control unit 104 determines that an operation on the display button 82A is detected by the display button input detection unit 101, it executes the process of step S605. If it determines otherwise, it executes the process of this step again. In step S605, the display control unit 104 ends the display in the display area (makes the display content displayed in the display area non-displayed).

[0018] Hereinafter, a method for setting the display areas of the first display content 60 and the second display content 61 in the display area setting unit 103 will be described while showing specific examples. FIG. 7 is a diagram showing an example of the display content. FIG. 7(a) shows an example of the first display content 60 among the two display contents assigned to the display button 82A. FIG. 7(b) shows an example of the second display content 61 among the two display contents assigned to the display button 82A. In FIG. 7(a), the first display content 60 is a display content indicating an intention to yield (prompt) an action of crossing a road, a crosswalk, etc. to a pedestrian. Note that the center line in the X direction (left-right direction) of the first display content 60 is defined as the center line 60C. In FIG. 7(b), the second display content 61 is a display content for notifying the surroundings that the object of the first display content 60 is in the process of crossing. Note that the center line in the X direction (left-right direction) of the second display content 61 is defined as the center line 61C.

[0019] FIG. 8 is a view of the front portion of the vehicle 1 as seen from the upper surface side, and shows the driver 50 when the display button 82A is operated. The line-of-sight direction A is the line-of-sight direction in the horizontal direction of the driver 50 when the display button 82A is operated. That is, a display target exists at the tip of the line-of-sight direction A. Note that the horizontal direction in the present embodiment refers to the components in the XZ plane. The display area setting unit 103 specifies a display center position P1 (which is a line segment on the display surface 6A) that is the intersection of the line-of-sight direction A in the horizontal direction of the driver 50 and the display surface 6A. Further, in the present exemplary embodiment, the center portion between the end portion (the right end 6R in the figure) located far from the display center position P1 and the display center position P1 is specified as the display center position P2 (which is a line segment on the display surface 6A).

[0020] FIG. 9 is a perspective view of the vehicle 1, and similarly to FIG. 8, it shows the driver 50 and the display unit 6 when the display button 82A is operated. In the present embodiment, when setting the display area for displaying the first display content 60, the display area setting unit 103 sets the display area so that the center line 60C of the first display content 60 coincides with the display center position P1. For this reason, it is easy for the display target existing ahead in the line-of-sight direction A of the driver 50 to recognize that it is the display target of the first display content 60. Further, when setting the display area for displaying the second display content 61, the display area setting unit 103 sets the display area so that the center line 61C of the second display content 61 coincides with the display center position P2. As described above, in the present embodiment, the display center position P2 is set at the center between the center line 60C of the first display content 60 and the right end 6R. That is, the second display content 61 is displayed at the center between the first display content 60 and the end portion at a far position on the display surface 6A. When the second display content 61 is displayed adjacent to the first display content 60 on the display surface 6A, the driver 50 will be confused as to which display content he or she is trying to convey. Also, when the second display content 61 is displayed adjacent to the right end 6R so as to be away from the first display content 60, it may be difficult for the display target (for example, an oncoming vehicle) for which the second display content 61 is to be conveyed to recognize. In the present embodiment, by arranging the right end 6R, the second display content 61, and the first display content 60 at equal intervals, it is possible to perform a display that is easy for each of the display target of the first display content 60 and the display target of the second display content 61 to recognize.

[0021] FIG. 10 is a diagram showing an example of the road conditions around the vehicle 1, and shows a situation where a pedestrian 51 having the intention to cross a crosswalk is waiting for an opportunity to cross. The driver 50 of the vehicle 1 operates the display button 82A to prompt the pedestrian 51 to cross the road, and a first display content 60 and a second display content 61 are displayed on the display surface 6A. The first display content 60 indicating the intention to yield (prompt) the pedestrian to perform an action of crossing a road, a crosswalk, etc. is displayed in the display area in the line-of-sight direction of the driver 50 on the display surface 6A, that is, in the direction where the pedestrian 51 as the display target exists. Therefore, the pedestrian 51 can easily recognize that it is a display for himself / herself. Further, the second display content 61 for notifying the surroundings that the pedestrian is in the process of crossing is displayed at the center between the first display content 60 and the right end 6R. Therefore, the oncoming vehicle 52 as the display target can easily recognize the situation where the vehicle 1 is prompting the pedestrian 51 to cross or that the pedestrian is actually crossing.

[0022] In addition, in the present embodiment, the display area of the first display content 60 is set according to the line-of-sight direction of the driver 50. However, when the display center position P1 is located near the end of the display unit 6, the display area may be set in the end area where the first display content 60 can be displayed.

[0023] Further, in the present embodiment, the display surface 6A is formed of a curved surface with the central portion convex forward. However, the present invention is not limited to this as long as the display unit 6 can be recognized from many surrounding directions. For example, it may be formed of a curved surface with the central portion convex backward.

[0024] Further, in the present embodiment, the second display content 61 is displayed at the center between the first display content 60 and the end at a position far from the display area of the first display content 60. However, the present invention is not limited to this. The second display content 61 may be displayed at a position where the first display content 60 is not displayed and where it is possible to notify the surroundings.

[0025] In addition, in the present embodiment, the display unit 6 is provided at the front part of the vehicle 1, but it may be provided at the side part or the rear part of the vehicle 1. For example, the first display content 60 may be displayed on the display unit provided at the front part, and the second display content 61 may be displayed on the display unit provided at the rear part.

[0026] In addition, in the present embodiment, the display content intended by the driver 50 is displayed by the driver 50 operating the display button 82, but the present invention is not limited to this. For example, the display content intended by the driver 50 may be displayed according to voice recognition of the driver 50's voice or the driver 50's actions (gestures), etc.

[0027] In addition, in the present embodiment, the line-of-sight direction of the driver 50 when the display button 82 is operated is recognized, but the present invention is not limited to this. For example, the line-of-sight direction of the driver 50 before and after operating the display button 82 may be recognized, the average value during that period may be taken, and the more frequent line-of-sight direction may be selected.

[0028] In addition, in the present embodiment, the display center position P1 is specified from the intersection of the line-of-sight direction of the driver 50 and the display surface 6A, but the present invention is not limited to this. The display area may be set using the line-of-sight direction of the driver 50, as long as a display area where the display target intended by the driver 50 can be easily recognized can be set.

[0029] In addition, in the present embodiment, the horizontal line-of-sight direction of the driver 50 is recognized, but the present invention is not limited to this. The vertical line-of-sight direction may also be recognized. In the display surface having a curved surface even in the vertical direction, it is also possible to display in the line-of-sight direction with a similar configuration.

[0030] In addition, in the present embodiment, the display content displayed on the display surface 6A by pressing the display button 82 is made non-displayed by pressing the display button 82 again, but the present invention is not limited to this. For example, another release button for releasing the display may be provided. Also, for example, monitoring means for monitoring the front may be provided, the display target may be specified by the monitoring means, and the display may be terminated when the action of the display target is completed.

[0031] In addition, in this embodiment, the display area setting unit 103 sets the display area using the line-of-sight direction of the driver 50, but the present invention is not limited to this as long as it can be set according to the position of the display target. For example, when the vehicle 1 is an autonomous vehicle, the display area may be set using the direction of the position of the display target. (Second Embodiment) In this embodiment, the arrangement and number of display units and the method of setting the display area are different from those in the first embodiment. In the following description, only the configurations different from those in the first embodiment will be described, and the common configurations will be omitted.

[0032] FIG. 11 is a diagram schematically showing the configuration of a vehicle 10 which is an example of a moving body equipped with the display system of this embodiment and capable of moving while holding the display system. The vehicle 10 has a right display unit 90, a center display unit 91, and a left display unit 92 respectively arranged at the front right corner, the center, and the front left corner. The right display unit 90 and the left display unit 92 are arranged such that the display surfaces 90A and 92A are inclined rearward with respect to the front surface. In this embodiment, the first display content 60 is displayed on the left display unit 92 according to the line-of-sight direction of the driver 50, and the second display content 61 is displayed on the right display unit 90 and the center display unit 91.

[0033] FIG. 12 is a block diagram of the display system control unit 152 of this embodiment. The display system control unit 152 has a display area setting unit (setting unit) 112 different from the display area setting unit 103 of the first embodiment.

[0034] FIG. 13 is a view of the front part of the vehicle 10 as seen from the upper surface side, showing the driver 50 when the display button 82A is operated. The line-of-sight direction A is the line-of-sight direction in the horizontal direction of the driver 50 when the display button 82A is operated. That is, there is a display target at the tip of the line-of-sight direction A. In this embodiment, the line-of-sight direction area of the driver 50 is divided into three areas so as to include each display unit, and the area including the right display unit 90 is defined as area R, the area including the center display unit 91 is defined as area S, and the area including the left display unit 92 is defined as area T.

[0035] The display area setting unit 112 sets which display unit is to display based on which area the line-of-sight direction of the driver 50 is included in. That is, if the line-of-sight direction of the driver 50 is included in area R, the first display content 60 is displayed on the right display unit 90. Similarly, if the line-of-sight direction of the driver 50 is included in area S, the first display content 60 is displayed on the center display unit 91, and if the line-of-sight direction of the driver 50 is included in area T, the first display content 60 is displayed on the left display unit 92.

[0036] In FIG. 13, since the line-of-sight direction A is included in area T, the first display content 60 is displayed on the display surface 92A of the left display unit 92. The second display content 61 is displayed on the display surfaces 90A of the right display unit 90 and 91A of the center display unit 91, which are the display units that are not displaying the first display content 60. Note that the second display content 61 may be displayed on a display unit different from the display unit on which the first display content 60 is displayed. For example, when the first display content 60 is displayed on the display surface 92A of the left display unit 92, the second display content 61 may be displayed only on the display surface 90A of the right display unit 90 without being displayed on the display surface 91A of the center display unit 91. In this case, since the first display content 60 and the second display content 61 are displayed separately, the first display content 60, which is the display for the display target intended by the driver 50, is more easily recognized. (Third Embodiment) In this embodiment, only the configuration different from the first embodiment will be described, and the description of the common configuration will be omitted.

[0037] FIG. 14 is an external view of a vehicle 11, which is an example of a moving body equipped with the display system of this embodiment and is an autonomous vehicle that does not require the operation of a driver. In addition to the configuration described in FIG. 1, the vehicle 11 has a front imaging device 71 for obtaining information around the vehicle 11.

The surrounding image acquisition unit 106 acquires an image in front of the vehicle 11 from the front imaging device 71. The vehicle motion determination unit 107 determines to execute the display operation of the vehicle 11 based on the image acquired by the surrounding image acquisition unit 106. When the purpose of displaying on the display unit 6 occurs and the execution of the display operation is determined, the display target identification unit 108 recognizes (identifies) the display target based on the image acquired by the surrounding image acquisition unit 106. The display target monitoring unit 109 monitors the behavior of the display target identified by the display target identification unit 108. The display area setting unit 111 sets the display areas of the first display content 60 and the second display content 61 based on the direction of the display target with respect to the vehicle 11.

[0039] FIG. 16 is a view of the front part of the vehicle 11 of the present embodiment as seen from the upper surface side. The direction of arrow B is the direction in which the display target identified by the display target identification unit 108 is located. The display area setting unit 111 specifies the display center position P1 of the display surface 6A having the direction of arrow B as the normal direction. Similar to the first embodiment, the display area of the second display content 61 is set at the display center position P2 set at the center between the display center position P1 and the left end 6L or the right end 6R of the display unit 6. In FIG. 16, the center between the end (right end 6R) at a position far from the display center position P1 and the display center position P1 is specified as the display center position P2. Thereafter, similar to the first embodiment, the display area of the first display content 60 is set so that the center line 60C of the first display content 60 coincides with the display center position P1. Also, the display area of the second display content 61 is set so that the center line 61C of the second display content 61 coincides with the display center position P2.

[0040] FIG. 17 is a flowchart showing a method for setting a display area according to the present embodiment. In step S701, the vehicle operation determination unit 107 determines to execute a display operation of the vehicle 11. In step S702, the display target identification unit 108 identifies a display target. Also, the display target monitoring unit 109 monitors the display target. In step S703, the display area setting unit 111 identifies the display center position P1 from the direction of the identified display target person and sets the display area of the first display content 60. In step S704, the display area setting unit 111 sets the display center position P2 from the left end 6L or the right end 6R of the display unit 6 and sets the display area of the second display content 61. In step S705, the display control unit 104 displays the first display content 60 and the second display content 61 in the display area set on the display surface 6A. In step S706, the vehicle operation determination unit 107 determines whether the action of the display target monitored by the display target monitoring unit 109 has achieved its purpose. If it is determined by the vehicle operation determination unit 107 that the action of the display target monitored by the display target monitoring unit 109 has achieved its purpose, this flowchart ends. If it is determined otherwise, the processing of this step is repeated. (Fourth Embodiment) In the present embodiment, only the configuration different from that of the first embodiment will be described, and the description of the common configuration will be omitted.

[0041] FIG. 18 is a diagram schematically showing the configuration of a vehicle 12 which is an example of a moving body equipped with the display system according to the present embodiment and capable of moving while holding the display system. The vehicle 12 has a rotatable display unit 93. The rotatable display unit 93 is configured to be rotatable within a certain range about the rotation center 93a.

[0042] FIG. 19 is a block diagram of the display system control unit 151 of the present embodiment.
