[0046] FIG. 3 is a magnified view in which the steering module 10 is magnified and seen from the vehicle rear side. As shown in FIG. 3, the display device 14 is provided with a main body portion 30. The main body portion 30 extends further to both left and right sides (both sides in the vehicle width direction) than the steering wheel 12, and is configured such that information is displayed on screens facing the vehicle seat 22.

[0047] More specifically, the main body portion 30 is provided with a center portion 30C, a right side display portion 30R and a left side display portion 30L. The center portion 30C is disposed at a vehicle width direction middle portion of the steering module 10, the right side display portion 30R is disposed at the vehicle right side relative to the vehicle width direction middle of the steering module 10, and the left side display portion 30L is disposed at the vehicle left side relative to the vehicle width direction middle of the steering module 10.

[0048] The right side display portion 30R is formed in a substantially rectangular plate shape. The right side display portion 30R is disposed to the vehicle front of a right side portion of the steering wheel 12 and, in plan view, is angled to the vehicle rear side in a direction toward the vehicle right side. The left side display portion 30L is formed in a shape with left-and-right symmetry with the right side display portion 30R. That is, the left side display portion 30L is formed in a substantially rectangular plate shape, is disposed to the vehicle front of a left side portion of the steering wheel 12 and, in plan view, is angled to the vehicle rear side in a direction toward the vehicle left side.

[0049] A surface at the vehicle rear side of the right side display portion 30R that opposes the driver seat is an electronic right display screen 32R, and a surface at the vehicle rear side of the left side display portion 30L that opposes the driver seat is an electronic left display screen 32L. In the descriptions below, where the right display screen 32R and left display screen 32L are not being distinguished, they are referred to simply as the display screens 32.

[0050] Each of the display screens 32 is equipped with a touch panel that the vehicle occupant may operate by touching. Accordingly, the display device 14 is configured such that the vehicle occupant may touch images and the like displayed at the display screen 32 and select functions corresponding with the images.

[0051] In the present exemplary embodiment, as an example, touch panels are provided at the whole of the display screens 32. That is, a touch panel is formed such that information is displayed at the whole of the surface of the vehicle rear side of the right side display portion 30R, and images displayed at the right side display portion 30R may be operated as appropriate. Similarly to the right side display portion 30R, a touch panel is formed such that information is displayed at the whole of the surface of the vehicle rear side of the left side display portion 30L, and images displayed at the left side display portion 30L may be operated as appropriate.

[0052] In particular, operation items with relatively high frequencies of operation are displayed in a region PR at the right side of the right side display portion 30R relative to the steering wheel and a region PL at the left side of the left side display portion 30L relative to the steering wheel 12.

[0053] For example, information concerning operations relating to an air conditioning apparatus, music playback and entertainment is displayed in the region PR, and the vehicle occupant may hold the right side display portion 30R and select images displayed in the region PR with a finger of the right hand. Meanwhile, information relating to driving support functions such as active cruise control, switching between driving modes and so forth is displayed in the region PL, and the vehicle occupant may hold the left side display portion 30L and select images displayed in the region PL with a finger of the left hand.

[0054] A region of the right side display portion 30R at the left side relative to the steering wheel 12 and a region of the left side display portion 30L at the right side relative to the steering wheel 12 are regions that are more difficult for the vehicle occupant to operate. Accordingly, operation items with relatively low frequencies of operation are displayed in these regions. For example, settings of a navigation system that are conducted while the vehicle V is parked and the like may be displayed in these regions. Operation items that do not need to be operated may be displayed in these regions as operation items with relatively low frequencies of operation. For example, items that the vehicle occupant does not need to operate, such as warning displays, social networking service (SNS) messages and the like may be displayed in these regions, and items that are not operated during driving but operated while the vehicle is stopped may be displayed in these regions.

[0055] In the present exemplary embodiment, the touch panels are provided at the whole surfaces of the display screens 32, but this is not limiting. Structures are possible in which touch panels are provided only at the region PR and the region PL, in which case a touch panel need not react when the hand of a vehicle occupant operating the steering wheel 12 touches the display screen 32. More specifically, consequent to a touch panel being provided only at a region of the right side display portion 30R extending at the right side beyond the steering wheel 12, misoperation due to a hand touching another portion of the right side display portion 30R in a state in which the hand is gripping the steering wheel 12 may be suppressed. Similarly, consequent to a touch panel being provided only at a region of the left side display portion 30L extending at the left side beyond the steering wheel 12, misoperation due to a hand touching another portion of the left side display portion 30L in a state in which the hand is gripping the steering wheel 12 may be suppressed.

[0056] As shown in FIG. 2, finger rest portions 31 are provided at surfaces at the opposite sides of the right side display portion 30R and left side display portion 30L from the sides thereof at which the display screens 32 are disposed. In the present exemplary embodiment, as an example of each finger rest portion 31, a protrusion portion for resting a finger is formed. When a finger is hooked on this protrusion portion, operability of the display screen 32 is improved. Alternatively, a recess portion that is recessed relative to the main surface for resting a finger may be provided as the finger rest portion.

[0057] A right operation switch 34R and a left operation switch 34L are provided at an upper edge of the main body portion 30. The right operation switch 34R is provided at the upper edge of the right side display portion 30R and is formed in a long, narrow shape whose length direction is in the vehicle width direction. In some embodiments, functions that may be operated regardless of information displayed at the display device 14 are assigned to the right operation switch 34R and left operation switch 34L. As an example in the present exemplary embodiment, a hazard lamp function is assigned to the right operation switch 34R and a high beam function is assigned to the left operation switch 34L, but this is not limiting.

[0058] A lower end portion of the center portion 30C of the main body portion 30 is disposed further upward than a lower end portion of the right side display portion 30R and a lower end portion of the left side display portion 30L. More specifically, the center portion 30C is disposed to the vehicle front relative to the right side display portion 30R and the left side display portion 30L, and the lower end portion of the center portion 30C is disposed further upward than the lower end of the steering wheel 12 as viewed from the vehicle rear side. A lower edge of the right side display portion 30R, a lower edge of the center portion 30C, and a lower edge of the left side display portion 30L are joined so as to be connected by a smoothly curved surface.

[0059] The steering wheel 12 includes the column portion 24, a base portion 40, a right grip portion 42R, a left grip portion 42L, a connecting portion 44, an upper right perimeter portion 46R and an upper left perimeter portion 46L.

[0060] As shown in FIG. 2, the column portion 24 projects from the instrument panel 16 through the module base 26 toward the vehicle rear. Sensors, which are capable of detecting a vehicle occupant and are not shown in the drawings, are provided at a distal end portion of the column portion 24. The sensors include a sensor that detects the whole face of a vehicle occupant, a sensor that detects the eyes, a sensor that detects an eyeline direction and a sensor that detects posture, or the like.

[0061] Air blowing holes, which are capable of blowing air toward the vehicle rear and are not shown in the drawings, are also provided at the distal end portion of the column portion 24. For example, the air conditioning apparatus is provided at the vehicle front side relative to the instrument panel 16 and is structured such that air whose temperature is controlled by the air conditioning apparatus is blown through the interior of the column portion 24 and from the air blowing holes toward the driver seat. Thus, because the air blowing holes are provided in the distal end portion of the column portion 24, there is no need to dispose a register at the instrument panel 16, and flexibility of design of the vehicle interior is improved. In addition, air may be blown from closer to the vehicle occupant than in a structure in which air is blown from the instrument panel 16.

[0062] As an example in the present exemplary embodiment, the column portion 24 is structured to be tiltable in the vertical direction relative to the module base 26. That is, the main body portion 30 is structured to be adjustable in position in the vertical direction independently from the steering wheel 12.

[0063] As shown in FIG. 3, the base portion 40 is provided at the column portion 24. The base portion 40 extends in the vehicle vertical direction and the vehicle width direction. The base portion 40 is turnably attached to a portion of the column portion 24 between a base end portion and the distal end portion.

[0064] The right grip portion 42R, which may be gripped by the vehicle occupant, is disposed at the right side relative to the base portion 40. The left grip portion 42L, which may be gripped by the vehicle occupant, is disposed at the left side relative to the base portion 40. The right grip portion 42R and left grip portion 42L both extend in the vehicle vertical direction and are formed in shapes with left-and-right symmetry about the center of the steering wheel 12.

[0065] A lower end portion of the base portion 40, a lower end portion of the right grip portion 42R and a lower end portion of the left grip portion 42L are connected in the vehicle width direction by the connecting portion 44. The connecting portion 44 is a long, narrow member that is disposed at the lower side relative to the column portion 24 and whose length direction is in the vehicle width direction. A vehicle width direction central portion of the connecting portion 44 is formed to be wider in the vehicle front-and-rear direction than both of vehicle width direction end portions.

[0066] An attachment piece 40A extends to the vehicle front side from a lower end portion of the base portion 40. The vehicle width direction central portion of the connecting portion 44 is fixed to the attachment piece 40A. A car horn switch may be provided at the vehicle width direction central portion of the connecting portion 44.

[0067] Both the vehicle width direction end portions of the connecting portion 44 are gently curved so as to gradually rise towards the two vehicle width direction sides, and are formed integrally with the right grip portion 42R and the left grip portion 42L.

[0068] The upper right perimeter portion 46R is provided at an upper end portion of the right grip portion 42R. The upper right perimeter portion 46R includes an upper right steering portion 48R and a right sightline guide portion 50R. The upper right steering portion 48R extends diagonally to the front-left side from the upper end portion of the right grip portion 42R. The right sightline guide portion 50R extends further to the vehicle front from an end portion of the upper right steering portion 48R and is connected with an upper end portion of the base portion 40.

[0069] The upper left perimeter portion 46L is provided at an upper end portion of the left grip portion 42L. The upper left perimeter portion 46L includes an upper left steering portion 48L and a left sightline guide portion 50L. The upper left steering portion 48L extends diagonally to the front-left side from the upper end portion of the left grip portion 42L. The left sightline guide portion 50L extends further to the vehicle front from an end portion of the upper left steering portion 48L and is connected with the upper end portion of the base portion 40.

[0070] A gap is provided between the upper right perimeter portion 46R and the upper left perimeter portion 46L. A base end region of the module base 26 may be viewed through this gap. Accordingly, a display portion such as a display screen or the like may be provided in a region of the module base 26 between the upper right perimeter portion 46R and upper left perimeter portion 46L.

[0071] Steering wheel switches are provided at one or both of the upper right perimeter portion 46R and the upper left perimeter portion 46L. As an example in the present exemplary embodiment, two right steering wheel switches 52R are provided at the upper right perimeter portion 46R. The two right steering wheel switches 52R are provided side by side in a face at the vehicle rear side of the upper right steering portion 48R. Respectively different functions are assigned to the two right steering wheel switches 52R. For example, functions such as a right indicator, switching between low beam and high beam, launching a voice entry device, and the like may be assigned to the right steering wheel switches 52R.

[0072] Meanwhile, two left steering wheel switches 52L are provided at the upper left perimeter portion 46L. The two left steering wheel switches 52L are provided side by side in a face at the vehicle rear side of the upper left steering portion 48L. Respectively different functions are assigned to the two left steering wheel switches 52L. For example, functions such as a left indicator, starting a windshield wiper, launching active cruise control, and the like may be assigned to the left steering wheel switches 52L.

[0073] The steering module 10 according to the present exemplary embodiment is structured as described above. The display device 14 and the steering wheel 12 are disposed to be spaced apart in the vehicle front-and-rear direction.

[0074] FIG. 4 is a magnified view in which the steering module 10 of FIG. 1 is magnified and seen diagonally from the rear right side. As shown in FIG. 4, a gap is provided between the right grip portion 42R of the steering wheel 12 and the right side display portion 30R of the display device 14. The gap is large enough that, in a state in which a vehicle occupant is gripping the right grip portion 42R, the hand of the vehicle occupant will not touch the right side display portion 30R.

[0075] In some embodiments, the gap between the right grip portion 42R and the right side display portion 30R is at least 5 cm and at most 30 cm, or at least 7 cm and at most 20 cm. A gap is also provided between the left grip portion 42L of the steering wheel 12 and the left side display portion 30L of the display device 14, of a similar size to the gap at the right side.

[0076] In the steering module 10 according to the present exemplary embodiment, the steering wheel 12 is structured to be stowable. For example, after the driving mode of the vehicle V is switched to the autonomous driving mode, if switching to the manual driving mode is not anticipated for a long time, the steering wheel 12 is stowed.

[0077] FIG. 5 is a view showing a state in which the steering wheel 12 is moved to a stowed position from the state in FIG. 2. In FIG. 5, a state in which the steering wheel 12 is at a usage position is depicted by two-dot chain lines and a state in which the steering wheel 12 is at the stowed position is depicted by solid lines.

[0078] As shown in FIG. 5, the steering wheel 12 is structured to be relatively movable in the vehicle front-and-rear direction with respect to the display device 14. For example, the steering wheel 12 is a structure that is locked in a state in which the column portion 24 of the display device 14 is inserted into the module base 26, and when this locked state is released, the column portion 24 is switched to a state that is relatively movable with respect to the module base 26.

[0079] As shown by the two-dot chain lines in FIG. 5, when the base portion 40 and column portion 24 are at the usage position, the vehicle occupant may steer and the display device 14 is spaced apart in the vehicle front-and-rear direction from the right grip portion 42R and left grip portion 42L of the steering wheel 12. In contrast, as shown by the solid lines, at the stowed position to which the steering wheel 12 is moved in the vehicle front-and-rear direction, the right grip portion 42R and the left grip portion 42L touch against the display device 14.

[0080] More specifically, in the present exemplary embodiment in plan view, an angle of the right side display portion 30R and an angle of the upper right steering portion 48R are substantially the same, and an angle of the left side display portion 30L and an angle of the upper left steering portion 48L are substantially the same. Therefore, at the stowed position, the right grip portion 42R and upper right steering portion 48R of the steering wheel 12 are in contact with the right side display portion 30R and right display screen 32R, and the left grip portion 42L and upper left steering portion 48L are in contact with the left side display portion 30L and left display screen 32L.

[0081] In the steering module 10 according to the present exemplary embodiment, a light source is provided in the interior of at least one of the right grip portion 42R, the left grip portion 42L, the connecting portion 44, the upper right perimeter portion 46R and the upper left perimeter portion 46L. The steering module 10 is configured such that the light source emits light when a vehicle occupant should grip the right grip portion 42R and left grip portion 42L.

[0082] In particular in the present exemplary embodiment, the material feel of a cover of the steering wheel 12 is the material feel of an ordinary synthetic leather, but the cover is formed of a material that enables the interior to be seen. When the light source emits light, the light is transmitted through the cover and is visible as if the surface of the cover is lighting up.

Operation

[0083] Now, operation of the steering module 10 according to the present exemplary embodiment is described.

[0084] As shown in FIG. 2, in the steering module 10 according to the present exemplary embodiment, the main body portion 30 of the display device 14 is disposed between the steering wheel 12 and the instrument panel 16, and the main body portion 30 extends further to both the left and right sides than the steering wheel 12. Therefore, display contents displayed at the display screen 32 may be seen by a vehicle occupant greatly moving their eyeline less than with a structure in which a display portion is provided at the instrument panel 16. Because the main body portion 30 extends to both the left and right sides relative to the steering wheel 12, hands gripping the steering wheel are not an obstacle when the vehicle occupant looks at the display screen 32.

[0085] In the display device 14 according to the present exemplary embodiment, the right operation switch 34R and left operation switch 34L are provided at the upper edge of the main body portion 30. These operation switches are formed in long, narrow shapes whose length directions are in the vehicle width direction. Therefore, the operation switches are easy to operate even in a state in which the eyeline of the vehicle occupant is directed forward.

[0086] In the display device 14 according to the present exemplary embodiment, because the right side display portion 30R and left side display portion 30L are in plate shapes, the display portions may be arranged in minimal space. In addition, because the right operation switch 34R is provided at the upper edge of the right side display portion 30R and the left operation switch 34L is provided at the upper edge of the left side display portion 30L, respectively different functions may be assigned thereto.

[0087] In the display device 14 according to the present exemplary embodiment, because a touch panel is provided at the display screen 32, the vehicle occupant may conduct operations without greatly moving their hand from the steering wheel 12.

[0088] In the display device 14 according to the present exemplary embodiment, operation items with high frequencies of operation are displayed in the region at the right side of the right side display portion 30R relative to the steering wheel 12 and the region at the left side of the left side display portion 30L relative to the steering wheel 12. Therefore, the vehicle occupant may easily touch these operation items. Operation items with relatively low frequencies of operation are kept displayed in other regions of the display screen. Therefore, convenience for the vehicle occupant may be improved relative to a structure in which these operation items are not displayed.

[0089] In the display device 14 according to the present exemplary embodiment, in a state in which the vehicle occupant grips the right side display portion or left side display portion in order to operate a touch panel, the vehicle occupant may rest a finger on a finger rest portion. Therefore, the vehicle occupant may conduct operations precisely even while driving.

[0090] In the display device 14 according to the present exemplary embodiment, because the vehicle width direction central portion of the lower edge portion of the main body portion 30 is disposed further upward than the lower end of the steering wheel 12, contact of the knee area of the vehicle occupant with the lower end portion of the main body portion 30 may be suppressed. Furthermore, because both the vehicle width direction end portions of the main body portion 30 are disposed further upward than the vehicle width direction central portion, the vehicle occupant may conduct operations without greatly moving their hands and may conduct operations easily.

[0091] In the display device 14 according to the present exemplary embodiment, because the column portion 24 is structured to be tiltable in the vertical direction relative to the module base 26, the relative position of the main body portion 30 with respect to the steering wheel 12 may be adjusted in accordance with the physical build of the vehicle occupant, posture and the like.

[0092] As shown in FIG. 3, in the steering wheel 12 according to the present exemplary embodiment, the lower end portions of the right grip portion 42R and the left grip portion 42L are connected to the lower end portion of the base portion 40 by the connecting portion 44, and the upper right perimeter portion 46R and upper left perimeter portion 46L are connected to the upper end portion of the base portion 40. Thus, because the upper portion and lower portion of the steering wheel 12 are respectively connected to the base portion 40, the steering wheel 12 is more resistant to deformation than a cantilever structure in which only one of the upper portion and lower portion of the steering wheel 12 is fixed to a steering column or the like.

[0093] In the steering wheel 12 according to the present exemplary embodiment, because the right steering wheel switches 52R are provided at the upper right perimeter portion 46R and the left steering wheel switches 52L are provided at the upper left perimeter portion 46L, the vehicle occupant may operate the steering wheel switches in the state in which the steering occupant is gripping the steering wheel 12.

[0094] In the steering wheel 12 according to the present exemplary embodiment, because the base portion 40 is turnably attached to the column portion 24, the steering wheel 12 may steer without the column portion 24 being turned. In particular, because the sensors capable of detecting the vehicle occupant are provided at the distal end portion of the column portion 24 in the present exemplary embodiment, the sensors are not turned even in states in which the steering wheel 12 is operated and detection accuracy of the sensors may be maintained.

[0095] In the steering wheel 12 according to the present exemplary embodiment, because the air blowing holes are provided at the distal end portion of the column portion 24, air may be blown from a position closer to the vehicle occupant than in a structure that blows air toward a vehicle occupant from air blowing holes provided at the instrument panel 16.

[0096] In the steering wheel 12 according to the present exemplary embodiment, as shown in FIG. 5, because the steering wheel 12 is structured so as to enable movement to the stowed position of the vehicle front side, the base portion 40 and column portion 24 may be moved to the stowed position and more space may be obtained in the vicinity of the driving seat than when steering by the vehicle occupant is necessary, such as during manual driving and the like.

[0097] Hereabove, the steering module 10 according to the present exemplary embodiment is described. It will be clear that numerous embodiments are possible within a scope not departing from the gist of the present disclosure. In the present exemplary embodiment, as shown in FIG. 3, the display screens 32 are provided as far as regions at the inner side of the steering wheel 12 as viewed from the vehicle rear side, but this is not limiting. For example, the structures of a first variant example shown in FIG. 6 and a second variant example shown in FIG. 7 may be employed.

First Variant Example

[0098] FIG. 6 is a view in which the steering module 10 according to the first variant example is seen from the vehicle rear side. As shown in FIG. 6, in the present variant example, a region between the right side display portion 30R and the left side display portion 30L is recessed to the vehicle front side relative to the right side display portion 30R and the left side display portion 30L.

[0099] More specifically, a region of the right side display portion 30R excluding the right display screen 32R is disposed further to the vehicle front side than the right display screen 32R, and a step portion 60R is formed between that region and the right display screen 32R. Similarly, a region of the left side display portion 30L excluding the left display screen 32L is disposed further to the vehicle front side than the left display screen 32L, and a step portion 60L is formed between that region and the left display screen 32L.

[0100] The right operation switch 34R and left operation switch 34L are narrower at base end sides than at distal end sides due to the step portion 60R and step portion 60L, but this is not limiting. That is, the step portions may be provided not only at the upper edge of the main body portion 30 and each distal end side and base end side may be formed with the same width, in which case the widths of the right operation switch 34R and left operation switch 34L may be the same at the distal end sides and base end sides.

[0101] In the present variant example, contact of the hands of the vehicle occupant gripping the steering wheel 12 with the main body portion 30 may be suppressed. Further, because the step portions 60R and 60L are formed between the right side display portion 30R and left side display portion 30L and the recessed region, stiffness of the main body portion 30 may be improved.

Second Variant Example

[0102] FIG. 7 is a view in which a steering module according to the second variant example is seen from the vehicle rear side. As shown in FIG. 7, in the present variant example, a region of the main body portion 30 between the right side display portion 30R and the left side display portion 30L is cut out.

[0103] More specifically, a region of the right side display portion 30R excluding the right display screen 32R is formed in a cut-out shape, and a pass-through portion 62R is formed penetrating in the thickness direction of the right side display portion 30R. Similarly, a region of the left side display portion 30L excluding the left display screen 32L is formed in a cut-out shape, and a pass-through portion 62L is formed penetrating in the thickness direction of the left side display portion 30L.

[0104] In the present variant example, contact of the hands of the vehicle occupant gripping the steering wheel 12 with the main body portion 30 may be suppressed. Further, because portions of the main body portion 30 are formed in indented shapes, the main body portion 30 may be reduced in weight. The vehicle occupant may view the vehicle front side of the display device 14 through the pass-through portions 62R and 62L. Note that the region of the right side display portion 30R excluding the right display screen 32R and the region of the left side display portion 30L excluding the left display screen 32L may simply be narrowed in the thickness directions relative to the right display screen 32R and left display screen 32L without being cut out.

[0105] In the exemplary embodiment and variant examples described above, two of the right steering wheel switches 52R are provided at the upper right perimeter portion 46R and two of the left steering wheel switches 52L are provided at the upper left perimeter portion 46L, but this is not limiting. For example, steering wheel switches may be provided at only one of the upper right perimeter portion 46R and the upper left perimeter portion 46L. Structures are also applicable in which no steering wheel switches are provided.
