Description

Technical Field

[0001] The present disclosure relates to a steering device. Background Art

[0002] Patent document 1 discloses a steering wheel having a function of detecting whether it is held by a passenger. The steering wheel of patent document 1 has a rim portion as a portion held by a passenger for rotational operation. The rim portion is formed into a substantially annular shape when viewed from the passenger side. A soft covering portion formed of foamed polyurethane is arranged around the core body, which is a portion of the rim portion that serves as a skeleton. In addition, a three-layer skin formed of different materials is arranged around the soft covering portion. As the outermost layer in the skin, a soft layer formed of foamed polyurethane is arranged. As the middle layer in the skin, a base cloth formed of fibers is arranged. As the innermost layer in the skin, a conductive layer formed of a conductive material is arranged. The conductive layer is a coating formed by applying a conductive coating to the inner side of the base cloth. The conductive layer imparts conductivity to the entire skin and acts as an electrode. When a passenger holds the rim portion, the capacitance between the skin and the passenger changes relative to the capacitance when the rim portion is not held. The detection substrate detects the holding condition of the rim portion based on the changed capacitance.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2016-165940

[0004] Regarding the steering wheel of Patent Document 1, a conductive layer is arranged over the entire circumference of the approximately annular rim portion. The potential of the conductive layer is sometimes different between the portion connected to the power source and the portion away from the portion connected to the power source. In addition, the conductive layer is not uniformly arranged over the entirety and in an ideal state. Therefore, regarding the steering wheel of Patent Document 1, the grip detection accuracy may fluctuate depending on the position gripped by the occupant. Summary of the invention

[0005] The present disclosure can be implemented as the following forms.

[0006] (1) According to one embodiment of the present disclosure, a steering device is provided. The steering device is provided on a mobile body, and includes: a rotating part rotatably mounted on the mobile body; and a gripping part connected to the rotating part, the gripping part including: a core part symmetrically arranged across the rotating part; and a covering part covering at least a portion of the core part, the covering part including: a first conductive part arranged on one side with respect to a symmetric plane of the core part and formed of a conductive material; and a second conductive part arranged on the other side with respect to a symmetric plane of the core part and formed of a conductive material, the first conductive part and the second conductive part being independent of each other, the steering device further including: a harness electrically connecting the first conductive part and the second conductive part; and a detector electrically connecting the first conductive part and the second conductive part via the harness, and detecting a gripping condition of the gripping part based on a change in capacitance generated in at least one of the first conductive part and the second conductive part.

[0007] According to the steering device of this mode, the first conductive part and the second conductive part are located on different sides relative to the symmetry plane and are independent of each other. Therefore, compared with a mode in which one conductive part covers the entire outer periphery of the core part, the area of ​​each conductive part is reduced. As a result, the fluctuation of the detection accuracy caused by the difference in the holding position can be reduced for the first conductive part and the second conductive part.

[0008] (2) Regarding the steering device of the above-mentioned method, it can be formed that the holding portion is a portion held by an occupant, and when a portion of the surface of the core portion on the side opposite to the occupant is set as a surface portion, and a portion on the side opposite to the surface portion is set as a back portion, the first conductive portion has: a first front conductive portion, which is configured to contact the surface portion; and a first rear conductive portion, which is configured to contact the back portion, the second conductive portion has: a second front conductive portion, which is configured to contact the surface portion; and a second rear conductive portion, which is configured to contact the back portion, and the wiring harness has: a first wiring harness, which electrically connects the first front conductive portion and the second front conductive portion; and a second wiring harness, which electrically connects the first rear conductive portion and the second rear conductive portion.

[0009] (3) Regarding the steering device of the above-mentioned method, it can be formed that the core body part has an annular shape, and when the rotating part is at a reference angle position, the uppermost part of the core body part which is the uppermost part in the vertical direction is located on the upper side relative to the rotating part in the vertical direction, and the covering part is arranged from the part of the core body part which is on the upper side relative to the center of rotation of the rotating part and does not include the uppermost part to the lowermost part of the core body part which is the lowermost part in the vertical direction.

[0010] According to the steering device of this aspect, compared with an aspect in which the first conductive portion and the second conductive portion are arranged from the uppermost portion to the lowermost portion of the core, the first conductive portion and the second conductive portion can each reduce fluctuations in detection accuracy due to differences in gripping locations.

[0011] In addition, the detection of the steering device being held by the passenger of the moving body is performed in order to detect that the passenger of the moving body is in a state where the moving body can be operated. On the other hand, when the passenger holds the uppermost portion of the gripping portion located on the upper side in the vertical direction, the passenger may not be able to instantly operate the steering device in the desired direction and by the desired amount. Therefore, when the uppermost portion of the core body is held, the requirement for detecting that the steering device is held is relatively low.

[0012] (4) Regarding the steering device of the above-mentioned method, it can be formed as follows: the holding portion is a portion held by an occupant, the portion of the surface of the core portion opposite to the occupant is set as a surface portion, and the portion on the opposite side of the surface portion is set as a back portion, the core portion has an annular shape, and the holding portion also has a light source body, which is arranged on the upper side in the vertical direction relative to the rotating portion when the rotating portion is in a reference angle position, and is arranged on the surface portion of the core portion. There are more than one light source body, and the light source body is configured to be able to irradiate light according to the condition of the moving body, and the covering portion is arranged on a portion of the core portion other than the portion where the light source body is arranged.

[0013] According to the steering device of this aspect, the grip portion may include a light source body and a cover portion.

[0014] The present disclosure can be implemented in various forms, for example, in the form of a vehicle equipped with a steering device, a method for manufacturing a steering device, and the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A. First Implementation Method:

[0029] Figure 1 1 is an explanatory diagram showing a vehicle VW provided with the steering device 1 according to the first embodiment. Figure 1 In FIG. 1 , the steering device 1 is shown in a simplified manner. Figure 1 In FIG. 1 , an X-axis, a Y-axis, and a Z-axis are shown, which are orthogonal to each other. The X-axis is the left-right direction of the vehicle VW. Figure 1 The direction from the front side of the paper to the back side is the positive direction of the X axis. The Y axis is a direction parallel to the direction in which the rotation axis AR described later extends. The Z axis is a direction orthogonal to the X axis and the Y axis. Figures 2 to 5 , Figures 8 to 10 In addition, Figure 1 In the diagram, the vertical direction is represented by the VU axis. The upward direction in the vertical direction is the positive direction of the VU axis.

[0030] Figure 2 Looking towards the +Y direction Figure 1 FIG. 1 is a diagram of a steering device 1. Figure 2 In FIG. 1 , the steering device 1 is shown in a simplified manner. Figure 3 is from Figure 2 The steering device 1 shown in the figure omits the cover 25. The cover 25 will be described later. Figure 1The steering device 1 shown is a device that is operated by a driver DR who is a passenger of the vehicle VW to achieve steering of the vehicle VW. The steering device 1 is connected to a rotation shaft AR protruding from the inside of the front portion FRO of the vehicle VW (see Figure 1 The steering device 1 is mounted on the vehicle VW via the rotation axis AR. Figure 2 and Figure 3 As shown in FIG. 1 , the steering device 1 includes a rotating portion 10, a grip portion 20, a wiring harness 30, and a detector 40. Figure 2 and Figure 3 In, omitted Figure 1 The rotation axis AR is shown. Figure 4 , Fig. 9 and Fig.10 The same is true in Chinese.

[0031] The rotating part 10 is mounted on the vehicle VW in a rotatable manner. Specifically, the rotating part 10 is Figure 1 The rotating shaft AR shown is fixedly passed through a hole 101 formed in the rotating portion 10 and is rotatably mounted on the vehicle VW. Figure 2 The rotating part 10 shown is connected to the holding part 20. In the present embodiment, when the rotating part 10 is not rotating, the rotating part 10 is symmetrical with respect to a plane including the Y axis and the Z axis. The symmetry plane of the rotating part 10 takes the position of the rotating part 10 including the Y axis and the Z axis as the "reference angle position of the rotating part 10". The position of the rotating part 10 at the reference angle position of the rotating part 10 is recorded as "the rotating part 10 is at the reference angle position". Figure 2 , the state where the rotating part 10 is at the reference angle position is shown. Figures 3 to 5 , Fig. 9 , Fig.10 The same is true in Chinese.

[0032] Figure 4 is from Figure 3 The steering device 1 shown in the figure omits the first covering portion 22 and the rotating portion 10. Figure 4 In the figure, the hole 101 formed in the rotating part 10 is shown for convenience. The first covering part 22 will be described later. The gripping part 20 is a part gripped by the driver DR who is a passenger of the vehicle VW. Figures 2 to 4 As shown, the grip portion 20 includes a core portion 21 , a first covering portion 22 , and a skin 25 .

[0033] Figure 4 The core portion 21 shown is a portion covered by the first covering portion 22 and the skin 25 (see Figure 2 and Figure 3 ).like Figures 2 to 4As shown, in this embodiment, the core portion 21 is symmetrically configured with respect to the rotating portion 10. In this embodiment, the core portion 21 is symmetrically configured with respect to a first symmetry plane PS1 including the Y axis and the Z axis when the rotating portion 10 is at the reference angle position.

[0034] Figure 5 Looking towards the +X direction Figure 4 The steering device 1 is shown in FIG. Figure 5 In the embodiment, the core part 21 is configured to be symmetrical with respect to the second symmetry plane PS2 including the X-axis and the Z-axis when the rotating part 10 is at the reference angle position. Figure 5 As shown, the second symmetry plane PS2 is a plane passing through the center of the core 21 in the Y direction when the core 21 is viewed in the X-axis direction. In the present embodiment, the portion of the surface of the core 21 facing the occupant is defined as the surface portion 21A, and the portion on the opposite side of the surface portion 21A is defined as the back portion 21B. Specifically, the portion of the surface of the core 21 facing the occupant is defined as the back portion 21B. Figure 1 and Figure 5 The portion opposite to the occupant and on one side relative to the second symmetry plane PS2 is set as the surface portion 21A. Figure 1 and Figure 5 As shown in FIG. 1 , a portion of the surface of the core portion 21 on the other side with respect to the second symmetry plane PS2 is referred to as a back surface portion 21B.

In addition, when the rotating part 10 is at the reference angle position, the lowermost part 21b of the core part 21 in the vertical direction is located on the lower side relative to the rotating part 10 in the vertical direction. In addition, in the present specification, "the upper side relative to the rotating part 10 in the vertical direction" means a range that is higher than the range occupied by the rotating part 10 in the vertical direction. An object A "being on the upper side in the vertical direction relative to the rotating part 10" does not mean being directly above the rotating part 10 in the vertical direction. That is, when projected in the vertical direction, the horizontal position of the object A may not overlap with the rotating part 10. Similarly, in the present specification, "the lower side in the vertical direction relative to the rotating part 10" means a range that is lower than the range occupied by the rotating part 10 in the vertical direction. The fact that an object A is “vertically below the rotating unit 10” does not mean that it is directly below the rotating unit 10 in the vertical direction. That is, when projected in the vertical direction, the horizontal position of the object A may not overlap with the rotating unit 10. Figure 4As shown, in this embodiment, the core portion 21 has a ring-shaped outer shape when viewed in the Y direction. The core portion 21 includes a core 210 and a soft cover portion 211 .

[0036] The core 210 is a part that becomes the skeleton of the core part 21. The core 210 is covered by the soft cover part 211. Figures 2 to 4 As shown, the core 210 is constructed to be symmetrical across the rotating part 10. In the present embodiment, the core 210 has an annular shape when observed in the Y direction. The core 210 is formed of an alloy of iron, aluminum, magnesium, etc. The core 210 is arranged on the inner circumference of the core 210 and is connected to a component extending in the X-axis direction, namely a fixing component. In addition, the fixing component is not shown in the accompanying drawings. The fixing component is formed of the same material as the core 210. A hole connected to the above-mentioned rotating axis AR when observed in the Y-axis direction is formed in the fixing component. The soft covering portion 211 covers the core 210 to protect the core 210. In the present embodiment, the soft covering portion 211 is formed of foamed polyurethane.

The first detection portion 220 is arranged on the outer surface of the core portion 21 in such a manner that Figure 6 One end portion 220a of the first detection portion 220 is shown as Figure 3 The first detection portion 220 is arranged on the outer surface of the core portion 21 in such a manner that Figure 6 The other end 220b of the first detection unit 220 is as shown in FIG. Figure 3 As shown, it contacts the lowermost portion 21b of the core portion 21.

Figure 8 As shown in FIG. 1 , a first shielding portion 222 and a first insulating portion 223 are arranged between the first conductive portion 221 and the core portion 21. The first conductive portion 221 in this specification is arranged on the outer surface of the core portion 21, which includes not only the case where the first conductive portion 221 is directly arranged on the outer surface of the core portion 21, but also the case where at least one of the first shielding portion 222 and the first insulating portion 223 is arranged between the first conductive portion 221 and the core portion 21. The same is true for the second conductive portion 231 described later. Figure 3 As shown, the first conductive portion 221 is arranged on the +X direction side, which is one side, with respect to the first symmetry plane PS1 of the core portion 21 .

[0040] The first conductive portion 221 is formed of a conductive material. In this embodiment, the first conductive portion 221 is a coating film formed by applying a conductive coating to the first insulating portion 223. As the conductive coating, a material in which conductive carbon or metal oxide powder is mixed in a coating resin can be used.

In this specification, the first front conductive portion 221a is configured to contact the surface portion 21A of the core portion 21, which includes not only the case where the first front conductive portion 221a is directly in contact with the surface portion 21A, but also the case where at least one of the first shielding portion 222 and the first insulating portion 223 is configured between the first front conductive portion 221a and the surface portion 21A. Specifically, as Figure 8 As shown in FIG. 1 , the first front conductive portion 221a is disposed on the −Y direction side, which is one side, with respect to the second symmetry plane PS2 of the core portion 21.

Specifically, the first rear conductive portion 221b is arranged on the +Y direction side, which is the other side, with respect to the second symmetry plane PS2 of the core portion 21. The first rear conductive portion 221b is arranged from the periphery of the uppermost portion 21a of the core portion 21 to the periphery of the lowermost portion 21b. In this embodiment, the length of the first rear conductive portion 221b along the outer periphery of the core portion 21 is the same as the length of the first front conductive portion 221a.

Figure 8 As shown, the first shielding portion 222 is arranged on the surface of the first insulating portion 223 opposite to the surface on which the first conductive portion 221 is arranged. The shape of the first insulating portion 223 will be described later. The first shielding portion 222 is formed by applying a coating material containing a conductive material to the first insulating portion 223. By arranging the first shielding portion 222 between the core 210 and the first conductive portion 221, the detection of the gripping of the gripping portion 20 by the first conductive portion 221 is stably performed.

[0043] The first insulating portion 223 insulates the first conductive portion 221 from the first shielding portion 222. The first insulating portion 223 is disposed between the first conductive portion 221 and the first shielding portion 222. Figure 6 As shown, the first insulating portion 223 has a sheet-like shape.

Specifically, the wiring harness 30 electrically connects the first conductive part 221 and the second conductive part 231 by electrically connecting the first conductive terminal 224 connected to the first conductive part 221 and the second conductive terminal 234 connected to the second conductive part 231. That is, the wiring harness 30 electrically connects the first conductive part 221 and the second conductive part 231 via the first conductive terminal 224 and the second conductive terminal 234. In the present embodiment, the wiring harness 30 includes a first wiring harness 310 and a second wiring harness 320. The first wiring harness 310 electrically connects the first front conductive part 221a and the second front conductive part 231a. One end of the first harness 310 is connected to the first front conductive terminal 224a, the second front conductive terminal 234a, the first front shielding terminal 225a, and the second front shielding terminal 235a, and the other end is connected to the detector 40. The second harness 320 electrically connects the first rear conductive portion 221b and the second rear conductive portion 231b. One end of the second harness 320 is connected to the first rear conductive terminal 224b, the second rear conductive terminal 234b, the first rear shielding terminal 225b, and the second rear shielding terminal 235b, and the other end is connected to the detector 40.

[0053] The detector 40 detects the gripping condition of the gripping portion 20 based on the change in capacitance generated in at least one of the first conductive portion 221 and the second conductive portion 231. The detector 40 electrically connects the first conductive portion 221 and the second conductive portion 231 via the harness 30. Figure 3 As shown in FIG. 1 , the detector 40 is disposed between the hole 101 formed in the rotating part 10 and the lowermost portion 21b of the core part 21. By disposing the detector 40 at this position, the appearance of the steering device 1 is improved compared with, for example, a method in which the detector 40 is disposed between the rotating part 10 and the uppermost portion 21a of the core part 21. In this embodiment, as shown in FIG. Figure 7 As shown, the detector 40 includes a first detector 410 and a second detector 420. Figure 3 Only the detector 40 is shown in the figure, but a first detector 410 and a second detector 420 are arranged between the hole 101 formed in the rotating part 10 and the lowermost part 21b of the core part 21. Figure 7As shown, the first detector 410 is electrically connected to the first front conductive part 221a, the second front conductive part 231a, the first front shield terminal 225a, and the second front shield terminal 235a via the first harness 310. Although not shown, the first detector 410 has various circuits including an oscillation circuit, a resonance circuit, a detection circuit, and an amplifier circuit.

[0054] If the gripping portion 20 is gripped by the occupant, the capacitance between at least one of the first front conductive portion 221a and the second front conductive portion 231a and the occupant changes relative to the capacitance in the state where the gripping portion 20 is not gripped, and the resonant frequency changes. The first detector 410 performs amplitude modulation on the changed resonant frequency, and after detection by the detection circuit, the signal is amplified by the amplifier circuit and output as a voltage to the ECU (Electronic Control Unit) of the vehicle VW (not shown). The ECU detects the gripping condition of the gripping portion 20 based on whether the voltage value is greater than a preset threshold value. In addition, the voltage of the first shielding portion 222 and the second shielding portion 232 detected by the first detector 410 is used to accurately output a voltage based on the capacitance between the occupant and the first front conductive portion 221a or the second front conductive portion 231a. The second detector 420 is electrically connected to the first rear conductive portion 221b, the second rear conductive portion 231b, the first rear shield terminal 225b, and the second rear shield terminal 235b via the second harness 320. The second detector 420 has the same structure as the first detector 410.

[0055] In the steering device 1 of the present embodiment, the first conductive portion 221 and the second conductive portion 231 are located on different sides relative to the first symmetry plane PS1 and are independent of each other. Therefore, the area of ​​each conductive portion is reduced compared to a method in which one conductive portion covers the entire periphery of the core portion 21. As a result, the fluctuation of the detection accuracy caused by the difference in the gripping position can be reduced for the first conductive portion 221 and the second conductive portion 231.

[0056] In addition, the steering device 1 has a harness 30 that electrically connects the first conductive portion 221 and the second conductive portion 231, and the detector 40 is electrically connected to the first conductive portion 221 and the second conductive portion 231 via the harness 30. For example, compared with a method in which the terminal that electrically connects the first conductive portion 221 and the detector 40 and the terminal that electrically connects the second conductive portion 231 and the detector 40 are not connected by the harness 30, it is difficult to cause a decrease in work efficiency when the first covering portion 22 is arranged on the core portion 21 when manufacturing the steering device 1. In this embodiment, there are: a first harness 310 that electrically connects the first front conductive portion 221a and the second front conductive portion 231a; and a second harness 320 that electrically connects the first rear conductive portion 221b and the second rear conductive portion 231b. For example, compared with a configuration without the first harness 310 and the second harness 320 , when manufacturing the steering device 1 , the work efficiency is less likely to be reduced when the first covering portion 22 is disposed on the core portion 21 .

[0057] In addition, in this specification, the first conductive portion 221 is arranged on one side and the second conductive portion 231 is arranged on the other side with respect to the symmetry plane of the core portion 21, which means that the first conductive portion 221 is arranged on one side and the second conductive portion 231 is arranged on the other side with respect to the first symmetry plane PS1 which is the symmetry plane of the core portion 21 configured to be symmetrical with respect to the rotating portion 10. That is, the "symmetry plane" in the above description does not include the second symmetry plane PS2.

[0058] B. Second Implementation Method:

[0059] Fig. 9 It is a schematic diagram of a steering system 1B according to the second embodiment. Fig. 9 and Figure 2 In the second embodiment, the holding portion 20 has the first light source body 51 and the second light source body 52, the core body 21 is covered by the second covering portion 22B instead of the first covering portion 22, and the shape of the skin 25B is different from that of the first embodiment. The other structures of the second embodiment are the same as those of the first embodiment, so the same reference numerals are marked and detailed description is omitted.

[0060] The first light source 51 and the second light source 52 are configured to irradiate light according to the condition of the vehicle VW. The first light source 51 and the second light source 52 of the present embodiment are lit to prompt the driver DR to hold the grip 20. When the rotating part 10 is at the reference angle position, the first light source 51 and the second light source 52 are arranged on the outer surface of the core part 21 on the upper side of the rotating part 10 in the vertical direction. In the present embodiment, the first light source 51 and the second light source 52 are arranged in the X direction across the uppermost part 21a of the core part 21. In addition, the first light source 51 and the second light source 52 are arranged on the surface part 21A of the core part 21 on the side opposite to the occupant. In the present embodiment, the first light source 51 and the second light source 52 are LEDs. The first light source 51 and the second light source 52 are electrically connected to the ECU of the vehicle VW, receive signals from the ECU and irradiate light.

[0061] Fig.10 This is a diagram for explaining the second covering portion 22B. Fig.11 2 is a diagram showing the second covering portion 22B in a state where the core portion 21 is not covered. The second covering portion 22B has the same structure as the first covering portion 22. The second covering portion 22B has a first detection portion 220B and a second detection portion 230B. The following describes the differences from the first covering portion 22. The second covering portion 22B is arranged in a portion of the core portion 21 except for a portion where the first light source body 51 and the second light source body 52 are arranged. The shapes of the first front conductive portion 221Ba and the second front conductive portion 231Ba of the second covering portion 22B are different from those of the first covering portion 22.

[0062] like Fig.11 As shown, in the first front conductive portion 221Ba of the second covering portion 22B, relative to Fig.10 The end 221Baa of the lowermost portion 21b of the core portion 21 close to the uppermost portion 21a is closer to the lowermost portion 21b than the end 221Bba of the first rear conductive portion 221Bb. That is, when the second covering portion 22B is observed to cover the core portion 21, the length of the first front conductive portion 221Ba of the second covering portion 22B along the outer periphery of the core portion 21 is shorter than the length of the first rear conductive portion 221Bb of the second covering portion 22B (refer to Fig.10 and Fig.11 ). In addition, if Fig.11 As shown in FIG. 1 , the first shield portion 222B and the first insulating portion 223B are configured to have a length corresponding to the length of the first front conductive portion 221Ba along the outer periphery of the core portion 21. Fig.10 As shown, in the surface portion 21A of the core portion 21 facing the occupant and located vertically above the rotating portion 10, there is a portion not covered by the first front conductive portion 221a. Fig. 9 The length of the first rear conductive portion 221Bb of the second cover portion 22B along the outer periphery of the core portion 21 is equal to Figure 3 The first rear conductive portions 221 b of the illustrated first covering portion 22 have the same length along the outer circumference of the core portion 21 .

[0063] Similarly, the second front conductive portion 231Ba of the second covering portion 22B has an end portion 231Baa on the side closer to the uppermost portion 21a relative to the lowermost portion 21b of the core portion 21, which is closer to the lowermost portion 21b than the end portion 231Bba of the second rear conductive portion 231Bb. That is, when the second covering portion 22B is arranged on the core portion 21 and observed, the length of the second front conductive portion 231Ba of the second covering portion 22B along the outer periphery of the core portion 21 is shorter than the length of the second rear conductive portion 231Bb of the second covering portion 22B. In addition, as Fig.11 As shown in FIG. 1 , the second shielding portion 232B and the second insulating portion 233B are configured to have a length corresponding to the length of the second front conductive portion 231Ba along the outer periphery of the core portion 21. Fig.10 As shown, in the surface portion 21A of the core portion 21 facing the occupant and located vertically above the rotating portion 10, there is a portion not covered by the first front conductive portion 221a. Fig. 9 The second light source body 52 is shown in FIG. The length of the second rear conductive portion 231Bb of the second cover 22B along the outer periphery of the core 21 is the same as the length of the second rear conductive portion 231b of the first cover 22 along the outer periphery of the core 21 .

[0064] In the present embodiment, when the rotating part 10 is at the reference rotation angle, when the steering device 1 is viewed in the +Y direction, the angle range A1 between the first detection part 220B and the second detection part 230B, which is centered on the center of the hole 101 formed in the rotating part 10, in the plane including the X-axis and the Z-axis, is approximately 50°. Fig.10 The angles shown are not exact.

[0065] like Fig. 9 As shown, the skin 25B of the second embodiment is configured to cover the core portion 21 and the second covering portion 22B, but not to cover the first light source body 51 and the second light source body 52 .

[0066] In the steering device 1B of the second embodiment, the grip 20 includes the first light source 51, the second light source 52, and the second cover 22B. The grip 20 includes the first light source 51 and the second light source 52, and emits light corresponding to the state of the moving object, thereby improving the convenience of the steering device 1B.

[0067] C. 3rd Implementation Method:

[0068] Fig.12 22C is a diagram for explaining the third covering portion of the third embodiment. Fig.12 As shown in the figure, the steering device 1C is different from the first embodiment in that it has a third covering portion 22C instead of the first covering portion 22. The other structures are the same as those of the first embodiment, so the same reference numerals are given and detailed descriptions are omitted. The third covering portion 22C has the same structure as the first covering portion 22. That is, the third covering portion 22C has a first detection portion 220C and a second detection portion 230C. The differences with respect to the first covering portion 22 are described below.

[0069] Although not shown in the figure, the third covering portion 22C is arranged from the portion of the core portion 21 that is on the upper side relative to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the lowermost portion 21b of the core portion 21. Specifically, the third covering portion 22C is configured so that the angle range A1 between the first detection portion 220C and the second detection portion 230C, which is centered on the center of the hole 101 formed in the rotating portion 10, is Fig. 9 and Fig.10 The second embodiment shown is similarly about 50°. Furthermore, although not shown in the third embodiment, the configuration is such that when the steering device 1C is viewed in the -Y direction, the angle range between the first detection portion 220C and the second detection portion 230C, centered on the center of the hole 101 formed in the rotating portion 10, is about 50°. Thus, the third covering portion 22C is arranged from the portion of the core portion 21 that is on the upper side relative to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the lowermost portion 21b of the core portion 21. That is, the first conductive portion 221C and the second conductive portion 231C are arranged from the portion of the core portion 21 that is on the upper side relative to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the lowermost portion 21b of the core portion 21.

[0070] Fig.12 The dimension D1 of the first detection portion 220C from one end to the other end is smaller than Figure 7 The first detection portion 220 of the first covering portion 22 shown has a dimension D2 from one end to the other end. The same is true for the second detection portion 230C of the third covering portion 22C.

[0071] In the third embodiment, compared with the manner in which the first conductive portion 221C and the second conductive portion 231C are respectively arranged from the uppermost portion 21a of the core portion 21 to the lowermost portion 21b, the first conductive portion 221C and the second conductive portion 231C can respectively reduce the fluctuation of the detection accuracy caused by the difference in the holding position. In addition, the detection of whether the steering device 1C is held is performed in order to detect that the occupant of the moving body is in a state in which the moving body can be operated. On the other hand, in the case where the portion of the gripping portion 20 located on the upper side in the vertical direction relative to the rotation axis AR is held by the occupant, the occupant may not be able to operate the steering device 1C in the desired direction and by the desired amount within an instant. Therefore, in the case where the uppermost portion 21a of the core portion 21 is held, the requirement for detecting that the steering device 1C is held is relatively low.

[0072] D. Other implementation methods:

[0073] D1. Other implementation methods 1:

[0074] (1) In the above-described embodiment, the steering device 1 is mounted on the vehicle VW. Alternatively, the steering device may be provided on a mobile object other than a vehicle, such as a ship or an airplane.

[0075] (2) In the above embodiment, the core 21 is configured to be symmetrical with respect to the second symmetry plane PS2 including the X-axis and the Z-axis when the rotating unit 10 is at the reference angle position. The core may not be configured to be symmetrical with respect to the plane including the X-axis and the Z-axis.

[0076] (3) In the above-mentioned embodiment, the holding portion 20 has an approximately annular shape. For example, the holding portion may have a rectangular or trapezoidal shape when viewed in the Y-axis direction. For example, the holding portion may have an approximately rectangular parallelepiped shape surrounding the rotating portion. In addition, the holding portion may have a shape that is connected to the left and right directions of the rotating portion and to the lower side in the vertical direction when the rotating portion is in the reference angle position. In addition, the holding portion may be two rod-shaped components that are respectively arranged in the left and right directions of the rotating portion when the rotating portion is in the reference angle position. For example, in a mode in which the holding portion does not have an approximately annular shape, when the rotating portion is in the reference angle position, the uppermost portion of the core portion may not be located on the upper side in the vertical direction relative to the rotating portion, and the lowermost portion of the core portion may not be located on the lower side in the vertical direction relative to the rotating portion.

[0077] (4) In the above embodiment, the core 210 is formed of an alloy of iron, aluminum, magnesium, etc. For example, the core may be formed of only iron, only aluminum, or only magnesium.

[0078] (5) In the above embodiment, the soft cover 211 is formed of foamed polyurethane. Alternatively, the soft cover may be formed of a soft material other than foamed polyurethane.

[0079] (6) In the first embodiment, the first covering portion 22 is arranged from the uppermost portion 21a to the lowermost portion 21b of the core portion 21. That is, the first covering portion 22 covers the entire core portion 21. In addition, the first covering portion only needs to be configured to cover at least a portion of the core portion. For example, the first covering portion may be arranged from a portion of the core portion that is located above the center of rotation of the rotating portion and does not include the uppermost portion to a portion of the core portion that is located below the center of rotation of the rotating portion and does not include the lowermost portion.

[0080] (7) In the above embodiment, the first conductive portion 221 and the second conductive portion 231 are coating films formed by applying conductive paint to the first insulating portion 223 and the second insulating portion 233. Alternatively, the first conductive portion and the second conductive portion may be conductive sheet-like members.

[0081] (8) In the above embodiment, the first detection unit 220 has the first shielding unit 222, and the second detection unit 230 has the second shielding unit 232. The first shielding unit 222 and the second shielding unit 232 are formed by applying a coating material containing a conductive material to the first insulating unit 223 and the second insulating unit 233. For example, the first detection unit may not have the first shielding unit, and the second detection unit may not have the second shielding unit. In addition, the first shielding unit and the second shielding unit may be, for example, conductive sheet-like members.

[0082] (9) For example, the first conductive portion and the second conductive portion may be configured to cover the outer periphery of the core portion but not the inner periphery. It is considered that when the passenger holds the gripping portion, the passenger usually holds the gripping portion at a position close to the outer periphery relative to the inner periphery of the core portion. Therefore, in a mode in which the first conductive portion and the second conductive portion cover the outer periphery of the core portion but not the inner periphery, detection based on the gripping of the passenger can be performed, and the areas of the first conductive portion and the second conductive portion can be reduced.

[0083] (10) In the above embodiment, the first front conductive terminal 224a is arranged on the other end 220b side relative to the one end 220a of the first detection part 220, and the first rear conductive terminal 224b is arranged on the other end 220b side relative to the one end 220a of the first detection part 220. For example, in a mode in which the detector is arranged between the uppermost part of the core part and the rotating part, the first front conductive terminal and the first rear conductive terminal may be arranged on the one end side of the first detection part. Similarly, the second front conductive terminal and the second rear conductive terminal may be arranged on the one end side of the second detection part.

[0084] (11) In the first embodiment, the first conductive portion 221 and the second conductive portion 231 are arranged from the periphery of the uppermost portion 21a to the periphery of the lowermost portion 21b of the core portion 21. Alternatively, for example, the first conductive portion and the second conductive portion may be arranged from the uppermost portion to the lowermost portion of the core portion without contacting each other.

[0085] (12) Fig.13 It is a cross-sectional view of a steering device 1v according to a modified example of the first embodiment. Fig.13 Equivalent to the first embodiment Figure 8 The steering device 1v includes a heater portion 240 between the surface of the core portion 21 and the first shield portion 222. Other aspects of the steering device 1v are the same as those of the steering device 1 of the first embodiment.

[0086] The heater unit 240 has a sheet-like structure as a main structure, that is, has a substantially rectangular shape and is flexible. The heater unit 240 can be formed by, for example, vapor-depositing carbon on a resin sheet such as PET (Polyethylene terephthalate) or polyamide, or performing a metal plating process.

[0087] The heater portion 240 is disposed on the surface of the core portion 21 at a position opposite to the rotating portion 10 in the surface of the core portion 21, with two long sides of the rectangle facing each other. The heater portion 240 is connected to a power source. The heater portion 240 generates heat by supplying power from the power source. As a result, the heat is conducted to the surface of the first conductive portion 221. Therefore, the occupant can comfortably hold the grip 20v of the steering device 1v even in winter when the temperature is relatively low.

[0088] Since the first shield portion 222 is disposed between the heater portion 240 and the first conductive portion 221, no capacitance is generated between the heater portion 240 and the first conductive portion 221. As a result, the detection of the gripping of the gripping portion 20v by the first conductive portion 221 is stably performed.

[0089] In this modification, the heater unit 240 has a sheet-like structure having a substantially rectangular outer shape and being flexible. However, the heater unit 240 may be formed by applying a conductive paint to the surface of the first shielding unit 222 .

[0090] The structure and function of the steering device 1v are described above by taking the side of the steering device 1v where the first detection unit 220 is arranged relative to the first symmetry plane PS1 as an example (see Figure 3 The same structure is also provided on the side of the steering device 1v where the second detection unit 230 is arranged relative to the first symmetry plane PS1 (see Figure 3 ).

[0091] D2. Other implementation methods 2:

[0092] (1) In the above embodiment, the first conductive portion 221 has a first front conductive portion 221a and a first rear conductive portion 221b, and the second conductive portion 231 has a second front conductive portion 231a and a second rear conductive portion 231b. For example, the first conductive portion may be a conductive portion on the surface of the core portion, from the surface portion to the back portion, and the second conductive portion may be a conductive portion on the surface of the core portion, from the surface portion to the back portion. In addition, for example, the first conductive portion may have a first front conductive portion and a first rear conductive portion, and the second conductive portion may be a conductive portion on the surface of the core portion, from the surface portion to the back portion. For example, the second conductive portion may have a second front conductive portion and a second rear conductive portion, and the first conductive portion may be a conductive portion on the surface of the core portion, from the surface portion to the back portion.

[0093] (2) In the above embodiment, the wiring harness 30 has a first wiring harness 310 and a second wiring harness 320. For example, in a mode where the first conductive portion has a first front conductive portion and a first rear conductive portion, and the second conductive portion is a conductive portion on the surface of the core portion from the surface portion to the back portion, one wiring harness can electrically connect the first front conductive portion and the second conductive portion. In addition, in a mode where the second conductive portion has a second front conductive portion and a second rear conductive portion, and the first conductive portion is a conductive portion on the surface of the core portion from the surface portion to the back portion, one wiring harness can electrically connect the second front conductive portion and the first conductive portion. In addition, in a mode where the first conductive portion and the second conductive portion are a conductive portion on the surface of the core portion from the surface portion to the back portion, the first conductive portion and the second conductive portion can be connected by one wiring harness.

[0094] (3) In the above embodiment, the detector 40 includes the first detector 410 and the second detector 420. For example, in a mode where the first conductive portion and the second conductive portion are one conductive portion from the surface portion to the back portion of the surface of the core portion, the detector can detect the gripping condition of the gripping portion based on a change in capacitance generated by at least one of the first conductive portion and the second conductive portion.

[0095] D3. Other implementation methods 3:

[0096] (1) In the third embodiment, the core portion 21 has an annular outer shape, and the third covering portion 22C is arranged from a portion of the core portion 21 that is located on the upper side relative to the center of rotation of the rotating portion 10 and does not include the uppermost portion 21a to the periphery of the lowermost portion 21b of the core portion 21. For example, in a mode in which the core portion has a substantially rectangular parallelepiped shape surrounding the periphery of the rotating portion, the first conductive portion and the second conductive portion can be arranged from a portion of the core portion that is located on the upper side relative to the center of rotation of the rotating portion 10 and does not include the uppermost portion to the periphery of the lowermost portion of the core portion.

[0097] (2) In the second and third embodiments described above, when the rotating portion 10 is at the reference rotation angle, when the steering device 1 is viewed in the +Y direction, the angle range A1 between the first detection portion and the second detection portion, centered at the center of the hole 101 formed in the rotating portion 10, in a plane including the X-axis and the Z-axis, is approximately 50°. For example, the angle range between the first rear conductive portion and the second rear conductive portion may be 10° or 90°.

[0098] (3) In the above embodiment, the lengths of the first conductive portion 221 and the second conductive portion 231 along the outer periphery of the core portion 21 are the same. In addition, the lengths of the first conductive portion and the second conductive portion along the outer periphery of the core portion may be different. For example, the length of the first conductive portion along the outer periphery of the core portion may be shorter than the length of the second conductive portion along the outer periphery of the core portion.

[0099] D4. Other implementation methods 4:

[0100] (1) In the second embodiment, the core part 21 has an annular shape, and the holding part 20 may include two light sources disposed on the upper side in the vertical direction relative to the rotating part 10 and disposed on the surface part 21A in the core part 21. For example, in a mode in which the core part has a substantially rectangular parallelepiped shape surrounding the rotating part, the two light sources may be disposed on the upper side in the vertical direction relative to the rotating part and disposed on the portion of the core part located on the rear side of the moving body.

[0101] (2) In the second embodiment, the holding portion 20 has two light sources located on the upper side in the vertical direction relative to the rotating portion 10. For example, the holding portion may have one or more light sources located at a position other than the upper side in the vertical direction. In this embodiment, the covering portion is arranged on a portion of the core portion other than the portion where the light sources are arranged.

[0102] (3) In the second embodiment, the angle range A1 between the first detection portion and the second detection portion, which is centered at the center of the hole 101 formed in the rotating portion 10, is approximately 50° in the plane including the X-axis and the Z-axis. Fig. 9 In the manner in which the first light source and the second light source are covered, the first detection unit is arranged around the first light source, and the second detection unit is arranged around the second light source.

[0103] (4) In the second embodiment, the grip portion 20 has two light sources, namely, the first light source 51 and the second light source 52. In addition, the grip portion may have one, three, or other light sources than two. In addition, the light source may flash to prompt the occupant to grip the grip portion, or may light up when the occupant does not grip the grip portion.

[0104] The present disclosure is not limited to the above-mentioned embodiments, and can be implemented in various structures within the scope of the main purpose. For example, the technical features of the embodiments corresponding to the technical features in each method recorded in the invention content column can be appropriately replaced or combined in order to solve part or all of the above-mentioned problems or to achieve part or all of the above-mentioned effects.
