Examples of the present invention will be described in detail below.

FIG. 1A is a diagram showing the vicinity of the driver's seat of the mobile MO on which the display device 10 according to the first embodiment is mounted. Further, FIG. 1B is a block diagram of the display device 10. The display device 10 will be described with reference to FIGS. 1A and 1B.

First, the mobile MO will be described with reference to FIG. 1A. The mobile MO is, for example, an automobile, a motorcycle, a ship, an aircraft, or the like. In this embodiment, a case where the mobile MO is composed of a vehicle such as an automobile will be described. Note that FIG. 1A shows the driver DR driving the mobile MO by a two-dot chain line.

The moving body MO has a steering handle (hereinafter, may be simply referred to as a handle) HA that performs a steering operation of the moving body MO. In this embodiment, the steering wheel HA is a steering wheel that is connected to the steering wheel of the moving body MO and changes the direction of the steering wheel by rotating around the rotation shaft AX.

Further, the mobile body MO has an instrument panel PA provided behind the steering wheel HA when viewed from the driver DR. For example, the instrument panel PA is embedded in the dashboard of the mobile MO. The instrument panel PA is, for example, a display showing the moving speed of the moving body MO, a display showing the route guidance information of the moving body MO, a display showing the state of the air conditioner of the moving body MO, and entertainment of the moving body MO. Includes an indicator showing the status of the device.

Although not shown, in the present embodiment, the moving body MO is a measuring instrument for measuring the moving speed and moving direction of the moving body MO, an air conditioner for controlling the temperature of the internal space of the moving body MO, and a moving body. A positioning device for positioning the MO, a navigation device for guiding the movement of the mobile MO, a recognition device for recognizing objects and weather around the mobile MO, an imaging device for imaging the surroundings of the mobile MO, and music and It has a playback device that plays a moving image. The mobile MO has a function of outputting information obtained from these devices as information indicating the state of the mobile MO (hereinafter referred to as mobile state information).

Further, in the present embodiment, the mobile body MO has a recognition device (not shown) that recognizes the state of the driver DR and the passenger of the mobile body MO. For example, the mobile body MO images the driver DR by the image pickup apparatus CA, and recognizes the positions of body parts such as the head, eyes, and hands of the driver DR and their changes. For example, the mobile MO outputs the recognition result by the recognition device as information indicating the state of the driver DR (hereinafter referred to as driver state information).

Further, in this embodiment, the mobile MO has various driving support functions. The mobile body MO performs various information processing on the above-mentioned mobile body state information and driver state information, for example, and information that supports the driving of the driver DR, for example, information on other moving bodies approaching the mobile body MO. And so on. The mobile MO outputs these driving support information as mobile state information.

Further, in this embodiment, the mobile MO has an automatic driving function of automatic driving level 2 or higher. It should be noted that the automatic driving level described here will be described in the case corresponding to the automatic driving level defined by the Society of Automotive Engineers (SAE). However, the level of automatic operation may be any level (classification) of automation related to various moving operations determined according to the type of the moving body MO and the like.

The mobile MO has a function of automatically operating the mobile MO, for example, by accelerating / decelerating or steering the mobile MO without going through the driver DR, depending on the conditions. As the mobile body state information, the mobile body MO outputs, for example, information indicating whether or not the automatic operation function of the mobile body MO is operating and details thereof.

For example, the moving body MO is information indicating that the moving body MO is in a state of being moved by automatic operation (hereinafter referred to as an automatic driving state) as the moving body state information, or the moving body MO is moved by manual operation. Outputs information indicating that the vehicle is in a state of being in a state (hereinafter referred to as a manual operation state). Further, the moving body MO outputs information indicating the automatic operation level of the moving body MO as the moving body state information. Further, the moving body MO is in an automatic operation state in which the moving body MO automatically steers as the moving body state information, or the moving body MO does not automatically steer (operations other than steering are automatically performed). It distinguishes whether it is in the automatic operation state and outputs it.

The device configuration of the mobile MO described above, and the mobile state information and the driver state information, which are the information generated by these devices, are only examples. For example, the mobile MO may not be equipped with some of the above-mentioned devices and functions. Further, the mobile MO may have a communication device. Then, for example, a part of the moving body state information may be generated outside the moving body MO, and the moving body MO may receive the moving body state information generated outside the moving body MO.

Next, the display device 10 will be described with reference to FIGS. 1A and 1B. The display device 10 acquires various information from the mobile MO and displays the information. In the present embodiment, the display device 10 includes a display panel group 11 including a plurality of display panels, each of which can display the information, and a control unit 12 that controls the display panel group 11.

As shown in FIG. 1A, the display panel group 11 is the handle HA as viewed from the operating position of the mobile MO (in this embodiment, the driver DR who sits in the driver's seat of the mobile MO and operates the handle HA). It is provided at the rear. In this embodiment, the display panel group 11 is provided between the handle HA and the instrument panel PA.

Further, the display panel group 11 has a main panel (first display panel or fixed display panel) 20 provided behind the handle HA when viewed from the operating position of the moving body MO, and the display panel group 11 as viewed from the operating position of the moving body MO. Includes a subpanel group 30 including a plurality of subpanels (second display panel or movable display panel) 31 and 32 provided behind the handle HA and movable relative to the main panel 20. Each of the main panel 20 and the sub-panels 31 and 32 has a configuration capable of displaying various information.

In this embodiment, the sub-panels 31 and 32 are provided between the handle HA and the instrument panel PA so that the display surface thereof rotates along the rotation direction of the handle HA. Further, each of the sub-panels 31 and 32 is configured to rotate independently of the rotation of the handle HA. The rotation of the subpanels 31 and 32 changes the relative position between the main panel 20 and the subpanels 31 and 32. For example, the main panel 20 is provided independently of the rotation of the handle HA and the sub-panels 31 and 32, and is fixed to the rear of the handle HA.

As shown in FIG. 1B, the control unit 12 has a mobile body information acquisition unit 40 for acquiring mobile body state information and a driver state acquisition unit 50 for acquiring driver state information. For example, the mobile body information acquisition unit 40 and the driver information acquisition unit 50 acquire the mobile body state information and the driver state information as described above from the mobile body MO, respectively.

Further, the control unit 12 has a panel control unit 60 that controls the display operation of the display panel group 11 based on the acquired mobile body state information and driver state information. The panel control unit 60 generates data (display data) for displaying the moving body state information on the main panel 20 and the sub-panels 31 and 32.

Further, the panel control unit 60 controls to move the sub-panels 31 and 32 so as to change the relative positions of the sub-panels 31 and 32 with respect to the main panel 20 according to the acquired mobile body state information. In this embodiment, the panel control unit 60 controls the rotation operation and the display operation of the sub-panels 31 and 32.

Further, in the present embodiment, the sub-panels 31 and 32 of the sub-panel group 30 have a configuration capable of receiving inputs for performing various operations of the mobile body MO from, for example, the driver DR. For example, each of the subpanels 31 and 32 is a touch panel type display. Therefore, in this embodiment, the display surfaces of the subpanels 31 and 32 function as an operation input area for receiving the operation input.

The control unit 12 has an operation reception information generation unit 70 that generates operation information received via the subpanels 31 and 32. The operation reception information generation unit 70 supplies the operation information to each device of the mobile MO corresponding to the received operation information.

For example, when the sub-panels 31 and 32 receive an operation input for adjusting the volume of the music being played by the mobile MO, the operation reception information generation unit 70 receives an operation for adjusting the volume to the music playback device. Provide information indicating that. Further, when the sub-panels 31 and 32 accept an operation such as a shift change of the mobile MO, the operation reception information generation unit 70 indicates that the operation of performing the shift operation is accepted for the transmission of the mobile MO. Supply information.

Further, the sub-panels 31 and 32 may accept an operation input regarding the main panel 20 in the display device 10, for example, an operation for switching the information displayed on the main panel 20. In this case, the operation reception information generation unit 70 supplies information indicating that the operation input for switching the display has been received to the main panel 20.

Next, the operations of the subpanels 31 and 32 will be described with reference to FIGS. 2A to 2C. In this embodiment, the sub-panels 31 and 32 move so that the relative positions with and from the main panel 20 change in three types based on the moving body state information. 2A to 2C show the positional relationship between the sub-panels 31 and 32 and the handle HA when viewed from the operating position of the moving body MO when the sub-panels 31 and 32 move.

In addition, in each of FIGS. 2A to 2C, the driver's seat SE in which the driver DR is seated is shown. In this embodiment, the driving position of the mobile MO corresponds to the eye position of the driver DR seated in the driver's seat SE. That is, each of FIGS. 2A to 2C schematically shows the main panel 20, the sub-panels 31 and 32, the steering wheel HA, and the like included in the visual field range of the driver DR seated in the driver's seat SE.

First, FIG. 2A shows sub-panels 31 and 32 arranged at a position (first position, hereinafter referred to as a standby position) P0 that overlaps with the main panel 20 behind the main panel 20 when viewed from the operating position of the moving body MO. It is a figure which shows.

For example, in the standby position P0, each of the subpanels 31 and 32 is hidden behind the main panel 20 when viewed from the operating position. Further, for example, the sub-panels 31 and 32 stop the display operation and the operation reception operation at the standby position P0.

For example, when the amount of the moving body state information acquired by the moving body information acquisition unit 40 is relatively small, the sub-panels 31 and 32 do not need to perform the display operation. Further, for example, when the moving body MO is in the manual operation state and the information indicating that the moving speed is equal to or higher than the predetermined speed is acquired, the driver DR recognizes all the information even if a large amount of information is displayed. It may not be possible.

When the mobile body information acquisition unit 40 and the driver information acquisition unit 50 acquire the above-mentioned information, the panel control unit 60 moves the sub-panels 31 and 32 to the standby position P0 and stops the operation. Then, the panel control unit 60 selects, for example, the acquired information according to the amount and the state of the moving body MO, and displays the selected information only on the main panel 20.

Next, FIG. 2B is a diagram showing subpanels 31 and 32 arranged at a position (second position, hereinafter referred to as a first display position) P1 where the display surface is exposed toward the operating position of the moving body MO. Is. Each of the subpanels 31 and 32 rotates so as to change the relative position with respect to the main panel 20. The display surfaces of the subpanels 31 and 32 can be visually recognized by the driver DR when arranged at the first display position P1.

For example, in this embodiment, each of the sub-panels 31 and 32 has one large display surface of the main panel 20 and one large display surface of the sub-panels 31 and 32 when viewed from the operating position as the first display position P1. It is arranged on the side of the main panel 20 so as to be a display surface. Further, the sub-panels 31 and 32 perform a display operation in conjunction with the main panel 20 at the first display position P1. For example, each of the sub-panels 31 and 32 stops the operation acceptance operation at the first display position P1.

For example, when the sub-panels 31 and 32 are arranged at the standby position P0, the moving body state information includes information on driving support of the moving body MO, for example, guidance information instructing to make a right / left turn at the next intersection. When information indicating the approach of a pedestrian or an obstacle is acquired, it may be necessary to temporarily notify the driver DR of the information.

For example, when the mobile body information acquisition unit 40 acquires information related to driving support, the panel control unit 60 moves the sub-panels 31 and 32 to the first display position P1. Then, the panel control unit 60 displays the driving support information on the sub panels 31 and 32 in cooperation with the main panel 20. As a result, the display device 10 displays various information with a high degree of freedom by expanding the display area by, for example, the display surfaces of the main panel 20 and the sub-panels 31 and 32.

In addition, only one of the subpanels 31 and 32 may move to the first display position P1. For example, when displaying information prompting a right turn as driving support information, or when displaying information indicating that an obstacle exists in front of the right front of the moving body MO, only the subpanel 32 is arranged at the first display position P1 ( It may be expanded) and the information may be displayed.

Next, FIG. 2C shows a position where the display surface is exposed (a third position, hereinafter referred to as a second display position or an operation position) P2 at a position separated from the main panel 20 when viewed from the operation position of the moving body MO. It is a figure which shows the sub-panels 31 and 32 arranged in.

For example, in the second display position P2, each of the subpanels 31 and 32 is arranged below the steering wheel HA as seen from the driver DR. Further, for example, at the second display position P2, each of the sub-panels 31 and 32 displays information different from that of the main panel 20.

Further, for example, at the second display position P2, each of the subpanels 31 and 32 performs an operation of receiving information input regarding the operation of the mobile body MO from the driver DR. That is, at the second display position P2, the sub-panels 31 and 32 perform a display operation and an operation reception operation.

For example, when the mobile MO is in the automatic driving state and the function of automatically steering the mobile MO is operating, the driver DR does not need to hold the steering wheel HA, and the surrounding situation of the mobile MO is not required. You may not always have to pay attention to. In this case, the driver DR acquires not only the information directly related to the movement of the mobile MO, but also a large amount of information such as information related to entertainment even when a large amount of information is displayed on the display panel group 11. be able to. In addition, the driver DR can perform operations other than driving the mobile MO.

For example, when the panel control unit 60 acquires information indicating that the moving body MO is in the automatic operation state as the moving body state information, the panel control unit 60 moves the sub-panels 31 and 32 to the second display position P2 and displays the display operation. And the operation reception operation is performed. Further, the operation reception information generation unit 70 generates operation information received via the subpanels 31 and 32 and supplies the operation information to each device in the mobile MO.

As a result, a large amount of information is aggregated and displayed in the vicinity of the steering wheel HA, and the driver DR can perform a large number of operations including the driving operation of the moving body MO in the vicinity of the steering wheel HA. Therefore, the driver DR can acquire a large amount of information without performing a large line-of-sight movement, and can perform a large number of operations related to the mobile MO without performing a large posture movement. Therefore, the burden on the driver DR due to the movement of the mobile body MO is reduced, and the movement can be performed comfortably.

The above-mentioned first display position P1 exemplifies the positions of the sub-panels 31 and 32 (that is, the positions where the sub-panels 31 and 32 perform the display operation) so that the display surface is exposed when viewed from the operating position of the moving body MO. It is a thing. Further, the second display position P2 exemplifies a position where the sub-panels 31 and 32 perform the display operation and the operation reception operation. That is, as a position for performing the display operation, the first display position P1 is a concept including the second display position P2, and the second display position P2 is one position aspect of the first display position P1.

In other words, in this embodiment, each of the sub-panels 31 and 32 stands by at least as a position overlapping the main panel 20 behind the main panel 20 when viewed from the operating position of the moving body MO when performing the display operation. It suffices to have a configuration that can be moved between the position P0 and the first display position P1 as a position where the display surface is exposed when viewed from the operating position. Further, each of the sub-panels 31 and 32 is configured to be movable at least between the standby position P0 and the second display position P2 when both the display operation and the operation reception operation are performed. good.

Next, with reference to FIG. 3, an example of the moving body state information and the operation flow when the subpanels 31 and 32 move based on the information will be described. First, as shown in FIG. 3, when the mobile body information acquisition unit 40 acquires the mobile body state information, the control unit 12 starts controlling the display panel group 11 (step S11).

First, the control unit 12 determines whether or not information indicating that the mobile MO is in the automatic operation state of level 2 or higher has been acquired as the mobile state information (step S12). Next, when the moving body MO is in the automatic operation state of level 2 or higher, the panel control unit 60 controls the sub-panels 31 and 32 to be secondly moved to the display position P2 to perform the display operation and the operation reception operation. (Step S13).

On the other hand, when the moving body MO is not in the level 2 or higher automatic driving state, the control unit 12 analyzes the moving body state information and determines whether the moving body MO is in the manual driving state (level 0 automatic driving state). (Step S14). Then, when it is determined that the moving body MO is in the manual operation state, the panel control unit 60 moves the sub-panels 31 and 32 to the standby position P0 and stops the operation (step S15).

Further, when it is determined that the moving body MO is not in the level 2 or higher automatic driving state and is not in the manual driving state (for example, in the level 1 automatic driving state), the panel control unit 60 may use the sub-panel 31 or The 32 is arranged at the first display position P1 as needed, and the display operation is performed.

As described above, for example, the subpanels 31 and 32 are arranged at the standby position P0 when the mobile body MO is in the manual operation state, and the first display position P1 or when the mobile body MO is in the automatic operation state. It is arranged at the second display position P2. As a result, the driver DR is in a state where at least a part of the automatic driving function is operating when the sub-panel 31 or 32 is arranged at the first display position P1 or the second display position P2. You can intuitively recognize that.

In addition, in FIG. 3, an example in which each of the subpanels 31 and 32 is displaced between the first and second display positions P1 and P2 according to the level of automatic operation has been described. However, the sub-panels 31 and 32 may be configured to change their positions, for example, depending on whether or not the moving body MO is in an automatic driving state for automatic steering.

In this case, the moving body information acquisition unit 40 receives information indicating that the moving body MO is in the manual driving state in which the moving body MO is being moved by manual driving as the moving body state information, and automatic driving in which the moving body MO is automatically steered. It suffices to acquire the information indicating that the moving body MO is in the state and the information indicating that the moving body MO is in the automatic driving state in which the steering is not automatically performed.

The state in which the mobile MO is in the manual operation state means that the driver DR is performing all operations related to the movement of the mobile MO (depending on the driver DR). Further, the state in which the moving body MO is automatically steered means that at least the moving body MO is in a state of being automatically steered. Further, the state in which the moving body MO is not automatically steered means a state in which the moving body MO is performing an operation related to the movement of the moving body MO other than steering, for example, acceleration / deceleration is performed by the moving body MO. Is automatically performed, and the steering is in a state of being dependent on the driver DR. The mobile body information acquisition unit 40 may acquire at least information indicating which of these operating states the mobile body MO is in as the mobile body state information.

Then, for example, the sub-panels 31 and 32 perform a display operation at the first display position P1 when the mobile body MO is not automatically steered, and a second display operation when the mobile body MO is automatically steered. The display operation and the operation reception operation may be performed at the display position P2 of. Thereby, for example, the driver DR can intuitively recognize whether or not the steering wheel HA needs to be operated.

Next, an example of other operation flows of the subpanels 31 and 32 will be described with reference to FIG. The flow shown in FIG. 4 shows an operation example when information other than the information regarding the operating state of the moving body MO is acquired as the moving body state information. Note that FIG. 4 corresponds to, for example, a flow when the mobile MO is in a manual operation state as a premise. First, the mobile body information acquisition unit 40 acquires the mobile body state information (step S21).

Next, the control unit 12 determines whether or not the information indicating that the movement of the moving body MO is hindered has been acquired as the moving body state information (step S22). The information indicating that the obstacle has occurred is, for example, information indicating that various objects such as pedestrians, other vehicles, and obstacles are approaching the moving body MO to less than a predetermined distance. ..

Then, when it is determined that the movement of the moving body MO is hindered, the panel control unit 60 arranges the sub-panel 31 or 32 at the first display position P1 and causes the display operation to be performed (step S23). For example, the panel control unit 60 selects a sub-panel corresponding to the position seen from the driver DR of an object approaching the moving object MO from the sub-panels 31 and 32, and causes the selected sub-panel to display the information. ..

Next, the control unit 12 determines whether or not the information indicating that the obstacle to the moving body MO has been resolved has been acquired as the moving body state information (step S24). Then, when it is determined that the trouble has been resolved, the panel control unit 60 moves the sub-panels 31 and 32 to the standby position P0 and stops the operation (step S25). If it is determined that the hindrance to the mobile MO has not been resolved, the panel control unit 60 continues to cause the sub-panels 31 and 32 to perform the display operation (returning to step S23).

Further, when it is determined in step S22 that the moving body MO is not hindered, the panel control unit 60 moves the sub-panels 31 and 32 to the standby position P0 and stops the operation (step S26).

As described above, each of the subpanels 31 and 32 is configured to change its relative position with respect to the main panel 20 in response to various events occurring in the moving body. Therefore, the driver DR can intuitively recognize various situations occurring in the moving body MO according to the positions of the subpanels 31 and 32.

Further, as described above as a specific example, when various objects such as pedestrians, other vehicles, and obstacles are approaching the moving body MO to a distance less than a predetermined distance, the panel control unit 60 of the sub-panels 31 and 32. Among them, the information of the object is displayed on the sub-panel corresponding to the position (direction) of the object when viewed from the driver DR of the moving body MO. As a result, the driver DR intuitively, for example, by looking at the sub-panel when displayed, not only that the object is approaching, but also that the object is approaching from the displayed sub-panel side. Can be recognized. Therefore, the driver DR can intuitively recognize various situations occurring in the mobile MO and accurately perform the necessary driving operation.

In this embodiment, as shown in FIG. 4, whether or not information indicating that the mobile MO is hindered has been acquired as the mobile state information, that is, pedestrians, other vehicles, and the like. The case where the position of the subpanel 31 or 32 changes depending on whether or not an obstacle or the like is close to the moving body MO has been described. However, the subpanels 31 and 32 may be displaced depending on other information.

For example, the sub-panel 31 or 32 receives information on the route guidance when the mobile body MO is moving by receiving the route guidance, and the mobile body information acquisition unit 40 acquires the information related to the route guidance as the mobile body state information. It may be configured to perform the display operation while being displaced according to the above. In this case, in step S22 shown in FIG. 4, the control unit 12 may determine "whether or not the information regarding the route guidance has been acquired" instead of "whether or not the moving body MO is hindered". ..

For example, the information regarding the route guidance is information indicating that the driver DR is approaching a position where the moving body MO should be operated when moving according to the route guidance, for example, an intersection where a right or left turn should be performed. As a specific example, consider a case where the mobile body information acquisition unit 60 acquires information indicating "the distance to the intersection where the left turn should be made is less than a predetermined distance" as the information regarding the route guidance in step S21.

In this case, the control unit 12 determines in step S22 that the information is information related to route guidance. Then, in step S23, the panel control unit 60 may arrange the sub-panel 31 at the first display position P1 to display the information. Then, the control unit 12 may determine in step S24 whether or not the moving body MO has acquired information indicating that the intersection has actually turned left, and may control the position of the subpanel 31 accordingly. This allows the driver DR to intuitively recognize, for example, that a left turn should be made at the intersection.

Further, the control unit 12 may acquire information on the distance to the position where the moving body MO should be operated, such as an intersection where the moving body MO should be turned, and may change the operation mode of the subpanel 31 or 32 accordingly. In this case, for example, the mobile body information acquisition unit 40 may acquire information on the intersection and the distance to the intersection as the mobile state information. As a specific example, the information indicating that the vehicle has approached 500 m before the intersection and the information indicating that the vehicle has approached 100 m before the intersection may be separately acquired.

Then, for example, the panel control unit 60 relatively small the exposure amount and display information from the main panel 20 of the sub-panel 31 500 m before the intersection, and the exposure amount and display information of the sub-panel 31 100 m before the intersection. The subpanel 31 may be controlled so as to be relatively large. By operating the sub-panel 31 or 32 in this way, the driver DR can more intuitively recognize the approach to the intersection or the like.

FIG. 5 is a schematic side view of the display device 10 when the sub-panels 31 and 32 are arranged at the second display position P2, that is, the operation position where the operation reception is performed. In addition to the display device 10, FIG. 5 schematically shows a steering wheel HA, a steering shaft SH connected to the steering wheel HA, and a shaft cover SC for the steering shaft SH. The shaft cover SC is fixed to the rotation of the steering shaft SH. The arrangement configuration of the subpanels 31 and 32 in the second display position P2 will be described with reference to FIG.

First, in this embodiment, the main panel 20 has a display function unit 20D exposed toward the steering wheel HA side, that is, the driver DR. The display function unit 20D is, for example, a liquid crystal unit. The surface of the display function unit 20D in the main panel 20 constitutes the display surface 20S of the main panel 20. That is, the main panel 20 is provided behind the handle HA when viewed from the operating position of the moving body MO, and has a display surface 20S provided on the operating position side.

Each of the sub-panels 31 and 32 has display function units 31D and 32D provided on the operating position side of the moving body MO, respectively, like the main panel 20. Further, the surface of the display function unit 31D in the sub panel 31 constitutes the display surface 31S of the sub panel 31, and the surface of the display function unit 32D in the sub panel 32 constitutes the display surface 32S of the sub panel 32. Therefore, the sub-panels 31 and 32 are provided behind the handle HA when viewed from the operating position of the moving body MO, and have display surfaces 31S and 32S provided on the operating position side, respectively.

Next, in the present embodiment, the sub-panel 31 has an operation input surface 31SB on the surface opposite to the display surface 31S (the surface on the instrument panel PA side) for receiving the operation input regarding the moving body MO and the main panel 20. .. Similarly, the sub-panel 32 has an operation input surface 32SB on the surface opposite to the display surface 32S (the surface on the instrument panel PA side) to receive the operation input.

That is, the display surfaces 31S and 32S of the sub-panels 31 and 32 function as front operation input surfaces. Further, the operation input surfaces 31SB and 32SB provided on the back sides of the display surfaces 31S and 32S in each of the subpanels 31 and 32 function as back side operation input surfaces.

Further, in this embodiment, the display surface 31S and the operation input surface 31SB function as an operation input area of the sub-panel 31. Similarly, the display surface 32S and the operation input surface 32SB function as an operation input area of the subpanel 32.

Further, as shown in FIG. 5, in the present embodiment, the operation input areas (display surfaces 31S and 32S and the operation input surfaces 31SB and 32SB) of the subpanels 31 and 32 are the second display positions (operation positions). In P2, it is arranged in front of the main panel 20 when viewed from the operating position of the moving body MO.

Specifically, in this embodiment, each of the subpanels 31 and 32 rotates around the rotation shafts RX1 and RX2 having an angle with respect to the rotation shaft AX of the handle HA, respectively. It is supported by the shaft cover SC behind the main panel 20.

For example, each of the sub-panels 31 and 32 has a drive source unit (not shown) for generating rotational power and a bearing unit fixed to the shaft cover SC so as to rotate around the rotation shafts RX1 and RX2, respectively (not shown). It has a rotation mechanism (not shown) and a rotation mechanism (not shown).

Therefore, each of the sub-panels 31 and 32 is arranged behind the main panel 20 in the standby position P0 and the first display position P1 when viewed from the operating position, and the handle HA is rotated in the second display position P2. It is arranged on the front side of the main panel 20 in the axial direction of the moving axis AX.

In other words, in this embodiment, the sub-panels 31 and 32 function as operation panels having operation input surfaces 31S and 31SB as operation input areas for receiving the operation input of the mobile body MO at the operation position P2. Further, the sub-panel group 12 functions as an operation panel group at the operation position P2.

Therefore, the display device 10 can receive the operation input of the moving body MO, rotates behind the handle HA in the rear of the handle HA when viewed from the operating position of the moving body MO, and rotates along the rotation direction of the handle HA. Operation input surface (display surfaces 31S and 32S or operation input) that can be moved to the operation position (second display position) P2 that is separated from the main panel 20 in the moving direction and is in front of the main panel 20 when viewed from the operating position. It has an operation panel (subpanels 31 and 32) having surfaces 31SB and 32SB).

Further, in the present embodiment, at least a part of the display surfaces 31S and 32S and the operation input surfaces 31SB and 32SB, which are the operation input areas of the subpanels 31 and 32, is at least a part of the second display position P2. It is placed below the handle HA. Further, in the present embodiment, the operation input areas of the subpanels 31 and 32 project from the side of the handle HA in the radial direction of the rotation axis AX of the handle HA at the second display position P2.

When the operation input area of the sub-panels 31 and 32 moves to the front of the main panel 20 at the operation position P2, the driver DR operates the mobile MO using the sub-panels 31 and 32. The movement of the arm can be greatly suppressed.

For example, as described above, the subpanels 31 and 32 are arranged at the operation position P2 when the moving body MO is in the automatic operation state. When the driver DR is seated in the driver's seat SE and does not hold the steering wheel HA, it can be said that the posture in which the arm is placed on the knee is natural and less fatigued. The operation positions P2 of the sub-panels 31 and 32 can be provided at positions where it is almost unnecessary to move the arm from the natural posture of the driver DR.

Therefore, the physical burden on the driver DR related to the operation input by the sub-panels 31 and 32 is greatly reduced. Further, when the operation is performed using the operation input surfaces 31SB and 32SB provided on the back sides (instrument panel PA side) of the display surfaces 31S and 32S, the driver DR performs the operation with only a slight movement of the wrist and fingers. It can be performed. Therefore, the effect of reducing the burden on the driver DR is great.

Further, for example, the driver DR can easily switch between the operation of the mobile body MO via the subpanels 31 and 32 and the operation of the mobile body MO by the handle HA. Therefore, for example, even during automatic operation, it is possible to easily shift to the operation of the handle HA (manual operation) in a short time. Therefore, for example, the burden on the driver DR is reduced even in the transition period (transition period) between the automatic operation state and the manual operation state.

Further, the operation position P2 is a position of the sub-panels 31 and 32 assuming that the moving body MO is in the automatic driving state and the driver DR releases his / her hand from the handle HA. Therefore, as shown in FIG. 1A, for example, the driver DR is in a state where his / her hand is placed near the foot of the driver DR and in a relaxed state by using the reclining of the driver's seat SE (the back is the driver's seat SE). It is assumed that the person is in close contact with the backrest and the upper body is tilted backward). Even in such a case, by arranging the sub-panels 31 and 32 at the operation position P2, the driver DR can perform various operation inputs in the relaxed state.

In this embodiment, the sub-panels 31 and 32 rotate around the rotation shafts RX1 and RX2 having an angle with respect to the rotation shaft AX of the handle HA, so that the sub-panels 31 and 32 are on the front side of the main panel 20. The case where it is configured to move to the operation position P2 of is described. However, the configurations of the subpanels 31 and 32 are not limited to this.

FIG. 6 is a diagram showing a sub-panel 31A at the operation position P2 of the display device 10A according to the first modification of the first embodiment. FIG. 6 is a schematic side view similar to FIG. 5 in the display device 10A. The display device 10A has the same configuration as the display device 10 except that the display device 10A has the sub-panel 31A instead of the sub-panel 31.

The sub-panel 31A is configured to rotate around the rotation axis AX of the handle HA and to move the display surface 31S along the axial DM of the rotation axis AX of the handle HA when moving to the operation position P2. Has been done. In this modification, the sub-panel 31A moves up and down (translates) from the main body MP that rotates around the rotation axis AX of the handle HA and the axial DM of the rotation axis AX of the handle HA. ) Has an elevating part EP. The display function unit 31D (display surface 31S) is provided on the surface of the elevating unit EP.

For example, when the sub-panel 31A moves to the rotation position corresponding to the operation position P2, the elevating unit EP rotates the display function unit 31D from the state of being housed in the main body unit MP (for example, the state of the standby position P0). A mechanism (elevating mechanism) for moving the moving shaft AX from the main body MP toward the operating position side in the axial direction is included.

In other words, in this modification, in the sub-panel 31A, the main body MP and the elevating part EP rotate behind the handle HA, and the elevating part EP moves up and down, so that the display surface 31S becomes the main panel 20. It is configured to move to the front side (operation position P2) of. As a result, the display surface 31S of the sub-panel 31A rotates and moves up and down. In this modification, the position of the operation input surface 31SB on the back side of the display surface 31S does not change even when the elevating unit EP is moved up and down.

FIG. 7 is a diagram showing a sub-panel 31B at the operation position P2 of the display device 10B according to the second modification of the first embodiment. FIG. 7 is a schematic side view similar to FIG. 5 in the display device 10B. The display device 10B has the same configuration as the display device 10 except that the display device 10B has the sub-panel 31B instead of the sub-panel 31.

The sub-panel 31B is configured to rotate around the rotation axis AX of the handle HA and to bend the display surface 31S toward the operating position when moving to the operating position P2. In this modification, the sub-panel 31B bends from the main body MP rotating around the rotation axis AX of the handle HA and the axial DM of the rotation axis AX of the handle HA toward the operating position side. It has a bent portion BP (which bends). The display function unit 31D (display surface 31S) is provided on the surface of the bent portion BP.

For example, the sub-panel 31B has a hinge portion 31H that connects the bent portion BP and the main body portion MP so that their main surfaces can be inclined to each other. Then, when the sub-panel 31B moves to the rotation position corresponding to the operation position P2, the bending portion BP changes from a state parallel to the main body portion MP (for example, a state of the standby position P0) in the axial direction of the rotation shaft AX. It includes a mechanism (bending mechanism) for bending from the main body MP toward the operating position side to the bent state.

In other words, in this modification, in the sub-panel 31B, the main body MP and the bent portion BP rotate behind the handle HA, and the bent portion BP bends so that the display surface 31S becomes the main panel 20. It is configured to move to the front side (operation position P2) of. As a result, the display surface 31S of the sub-panel 31B rotates and bends. In this modification, when the bent portion BP is bent, the operation input surface 31SB on the back side of the display surface 31S is also configured to be bent in the same manner.

The display device 10 may have, for example, a sub-panel 31A of the display device 10A or a sub-panel 31B of the display device 10B. That is, the sub-panels 31, 32, 31A and 31B rotate behind the handle HA when viewed from the operating position of the moving body MO, are separated from the main panel 20 in the rotation direction, and are separated from the main panel 20 when viewed from the operating position. It has operation input surfaces (display surfaces 31S and 32S and operation input surfaces 31SB and 32SB) that can be moved to the operation position P2 in front of the display surface. Therefore, it is possible to easily receive the operation input regarding the moving body MO.

In this embodiment, the main panel 20 may be supported by the shaft cover SC so as to rotate along the rotation direction of the handle HA within a range that does not interfere with the sub panels 31 and 32. Therefore, in this embodiment, each of the main panel 20 and the sub-panels 31 and 32 has a rotatable configuration. Therefore, it is possible to display information about the mobile MO with a high degree of freedom.

Further, the display panel group 11 is provided behind the handle HA. Therefore, the driver DR can recognize various information with almost no movement of the line of sight. Further, the sub-panels 31 and 32 perform display operations with a high degree of freedom while changing the relative positions between the sub-panels 31 and 32 and the main panel 20. Therefore, the driver DR can intuitively recognize, for example, the state of the mobile MO.

Further, the display device 10 may be configured to adjust the information display position in the display panel group 11 based on the position of the eyes of the driver DR. For example, the panel control unit 60 may acquire information regarding the eye position of the driver DR from the driver information acquisition unit 50, and determine and change the display area in the display surface 20S of the main panel 20 based on the information. good. Similarly, the panel control unit 60 may determine and change the display area in the display surfaces 31S and 32S of the subpanels 31 and 32 based on the information regarding the position of the eyes.

In other words, the driver information acquisition unit 50 may acquire information regarding the eye position of the driver DR who drives the moving body MO at the driving position of the moving body MO as the driver state information. Then, the display panel group 11 (main panel 20, and sub-panels 31 and 32) may display in a region determined based on the position of the eyes.

Thereby, for example, the area where the information is displayed can be finely adjusted according to the height and sitting height of the driver DR. Therefore, for example, it is suppressed that information is displayed at a position overlapping the steering wheel HA (a position that becomes a blind spot of the steering wheel HA) when viewed from the driver DR. Therefore, the driver DR can clearly see the information display.

In this embodiment, the case where the sub-panel group 30 is composed of two sub-panels 31 and 32 has been described. However, the configuration of the subpanel group 30 is not limited to this. The display device 10 may have at least one subpanel (for example, the subpanel 31).

Further, in the above, the case where the main panel 20 and the sub-panels 31, 32, 31A and 31B are configured to rotate behind the handle HA has been described. However, the operation configurations of the main panel 20 and the sub-panels 31, 32, 31A and 31B are not limited to this. For example, the sub-panels 31 and 32 may move relative to the main panel 20 only by movement other than rotation, for example, translation.

Further, in the above, the case where the sub-panels 31, 32, 31A and 31B can be moved to the operation position P2 on the operation position side of the main panel 20 and the operation input is received at the operation position P2 has been described.

However, the operation configurations of the subpanels 31, 32, 31A and 31B are not limited to this. For example, even if each of the subpanels 31, 32, 31A and 31B is configured to be movable between the standby position P0 (first position) and the first display position P1 (second position). good. Further, each of the subpanels 31, 32, 31A and 31B may receive an operation input at the first display position P1.

Further, in the present embodiment, each of the sub-panels 31 and 32 moves to a position where the display surfaces 31S and 32S are arranged on the side of the display surface 20S of the main panel 20 as the first display position P1. Explained.

However, as described above, the first display position P1 may be a position where the display surface is exposed when viewed from the operating position of the moving body MO. That is, the first display position P1 is a concept including the second display position P2. Therefore, for example, the sub-panels 31 and 32 may be configured to be movable between the standby position P0 and the second display position P2 as the first display position P1.

That is, for example, at least one of the sub-panels 31, 32, 31A and 31B is operated with a standby position P0 (first position) that overlaps with the main panel 20 behind the main panel 20 when viewed from the operating position of the moving body MO. It suffices if it can be moved between the first display position P1 (second position) where the display surface is exposed when viewed from the position. As a result, it is possible to display information with a high degree of freedom, for example, the main panel 20 always performs a display operation, and the sub panel 31 or 32 performs a display operation as needed.

Further, in the above, the case where each of the sub-panels 31, 32, 31A and 31B is configured to be hidden behind the main panel 20 at the standby position P0 has been described. However, each of the subpanels 31, 32, 31A and 31B may be configured to move relative to the main panel 20. That is, each of the sub-panels 31, 32, 31A and 31B may be provided behind the handle HA when viewed from the operating position of the moving body MO and may be movable with respect to the main panel 20. Thereby, for example, the main panel 20 and the sub-panels 31 and 32 that move relative to the main panel 20 can be used to display information with a high degree of freedom.

Further, in the above, the case where each display surface (for example, display surface 31S) and operation input surface (for example, operation input surface 31SB) of each of the subpanels 31, 32, 31A and 31B functions as an operation input area has been described. However, when the operation input area is provided, any area of the subpanels 31, 32, 31A and 31B may function as the operation input area.

Further, in the above, the case where each of the subpanels 31, 32, 31A and 31B is configured to accept the operation input has been described. However, the subpanels 31, 32, 31A and 31B may have a configuration that only performs a display operation.

As described above, in the present embodiment, the display device 10 is provided behind the steering handle HA of the moving body MO when viewed from the operating position of the moving body MO, and is a first display panel (main panel) capable of displaying information. 20) and at least one second display panel (sub-panel 31) provided behind the steering wheel HA when viewed from the driving position, movable with respect to the first display panel, and capable of displaying information. And 32) and. Therefore, it is possible to provide a display device capable of displaying various information about the moving body MO in an easy-to-understand manner with a high degree of freedom.

Further, for example, the at least one second display panel is viewed from the first position P0, which overlaps with the first display panel behind the first display panel when viewed from the operation position, and from the operation position. The display surfaces 31S and 32S can be moved between the exposed second position P1 and the display surface P1. Therefore, for example, the first and second display panels can be selectively used based on various conditions, and information can be displayed with a high degree of freedom.

Further, for example, the at least one second display panel is configured to rotate along the rotation direction of the steering handle HA behind the steering wheel HA when viewed from the driving position. Therefore, the peripheral area of the steering wheel HA can be used as a display area with a high degree of freedom. Therefore, the movement of the line of sight when the driver DR visually recognizes the display panel is reduced, and the burden on the driver DR is reduced.

Further, for example, the at least one second display panel can accept the operation input of the mobile body MO. Therefore, it is possible to provide a display device capable of displaying various information about the moving body MO with a high degree of freedom and easily receiving an operation input related to the moving body MO.

Further, for example, the at least one second display panel receives the operation input on the operation input surface (for example, the operation input surface 31SB) provided on the opposite side of the display surface (for example, the display surface 31S). Therefore, the burden on the driver DR related to the operation of the mobile MO is reduced.

Further, for example, the display device 10 has an acquisition unit (driver information acquisition unit 50) for acquiring information regarding the eye position of the driver DR who drives the mobile body MO at the operation position of the mobile body MO. In addition, the first display panel can display information in a region defined based on the position of the eyes of the driver DR. Therefore, the information can be displayed so that the driver DR can be surely visually recognized.
