BEST MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, embodiments will be specifically described with reference to the drawings.

[0010] Note that each of the embodiments described below shows comprehensive or specific examples. Numerical values, shapes, materials, components, arrangement positions of components, connection forms, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, components not described in the independent claims are described as optional components.

[0011] Also, each figure is a schematic diagram and is not necessarily drawn precisely. In each figure, the same reference numerals are given to the same components.

[0012] In the following embodiments, expressions such as rod-shaped and horizontal direction are used. For example, the rod-shaped and horizontal direction not only mean completely rod and horizontal direction, but also substantially rod and horizontal direction, that is, including an error of about several percent. Also, the rod and horizontal direction mean rod and horizontal direction within the range in which the effects according to the present disclosure can be achieved. The same applies to other expressions using "shape" and "direction".

[0013] (Embodiment) <Configuration and Function in Automatic Mode> First, with reference to FIGS. 1 to 3, the vehicle steering device 1 of the present embodiment will be described.

[0014] FIG. 1 is a perspective view showing a vehicle steering device 1 in which a pair of grips 10 can be automatically rotated. (a) of FIG. 1 shows a case where the steering position during driving is in the neutral position. (b) of FIG. 1 shows a case where a pair of grips 10 are tilted and in a horizontal posture. (c) of FIG. 1 shows a case where the grip 10 on the door 9 side of the vehicle 3 adjacent to the vehicle steering device 1 is in a vertical posture and the other grip 10 is in a horizontal posture. (d) of FIG. 1 shows a case where a pair of grips 10 are tilted and in a horizontal posture and the table 50 is pulled out. FIG. 2 is a block diagram showing the vehicle steering device 1 in which a pair of grips 10 can be automatically rotated. FIG. 3 is a perspective view showing the state of the table 50 in the vehicle steering device 1 in which a pair of grips 10 can be automatically rotated. (a) of FIG. 3 shows a case where a pair of grips 10 are tilted and in a horizontal posture and the table 50 is stored in a storage space in the column cover 6 that covers the lower part of the steering column 4. (b) of FIG. 3 shows a case where a pair of grips 10 are tilted and in a horizontal posture and the table 50 is pulled out from the storage space in the column cover 6.

[0015] In FIG. 1 and the like, the vehicle steering device 1 provided in the vehicle 3 with the driver's seat on the left side in the traveling direction is exemplified. Note that the vehicle steering device 1 of the present disclosure may be mounted on a vehicle 3 with the driver's seat on the right side in the traveling direction.

[0016] The vehicle steering device 1 is a device that can give a steering angle to the steering wheel of the vehicle 3, and is also a device that can change the posture of the grip 10 on the steering wheel arranged in front of the driver's seat of the vehicle 3.

[0017] Specifically, as shown in FIGS. 1 and 2, the vehicle steering device 1 includes a spoke 2, a pair of grips 10, a pair of first drive units 21, and a control unit 30.

[0018] The spoke 2 is connected to the steering column 4 and is a rod-shaped member that extends in the left-right direction from the steering column 4 when the steering position during driving is at the neutral position. Note that the neutral position is a state in which the spoke 2 is in a posture parallel to the left-right direction (horizontal direction) so that the vehicle 3 can travel straight.

[0019] A pair of grips 10 are arranged at both ends of the spoke 2 in the left-right direction. That is, the pair of grips 10 are arranged on the left and right of the spoke 2. Each of the pair of grips 10 has an arc shape. Note that in this embodiment, a configuration in which the pair of grips 10 have an arc shape is illustrated, but the configuration is not limited thereto, and the pair of grips 10 may be linear.

[0020] The pair of grips 10 are rotatable with respect to the spoke 2. The pair of grips 10 are automatically rotatable with respect to the spoke 2 by a pair of first drive units 21 controlled by the control unit 30. Each of the pair of grips 10 is separately rotatable independently about the left-right direction of the spoke 2. For this reason, each of the pair of grips 10 is rotatable independently of each other about the left-right direction of the spoke 2.

[0021] Each of the pair of grips 10 has a first portion and a second portion.

[0022] The first portion is a portion that extends toward the ceiling direction of the vehicle 3 with respect to the spoke 2 when the steering position during driving is at the neutral position.

[0023] The second portion is a portion that extends toward the floor direction of the vehicle 3 with respect to the spoke 2 when the steering position during driving is at the neutral position.

[0024] In a pair of grips 10, when the steering position during operation is at the neutral position, the length of the first part and the length of the second part are different. Let the part with the longer length among the first part and the second part be the long part 11a, and the part with the shorter length be the short part 12a. In Fig. 1(a), an example is shown where, as the neutral position, the long part 11a extends toward the floor side of the vehicle 3 and the short part 12a extends toward the ceiling side of the vehicle 3, but it is not limited to this. For example, as the neutral position, the long part 11a may extend toward the ceiling side of the vehicle 3 and the short part 12a may extend toward the floor side of the vehicle 3. Therefore, when the first part is the long part 11a, the second part is the short part 12a, and when the first part is the short part 12a, the second part is the long part 11a.

[0025] As shown in Fig. 1(a), each of the pair of grips 10 is rotatable such that during operation, the short part 12a rotates toward the ceiling side of the vehicle 3 and the long part 11a rotates toward the floor side of the vehicle 3. That is, since each of the pair of grips 10 is rotatable with respect to the spoke 2, it is possible to make the long part 11a extend toward the floor side of the vehicle 3 with respect to the spoke 2, and it is possible to make the short part 12a extend toward the ceiling side of the vehicle 3 with respect to the spoke 2. Note that each of the pair of grips 10 may also be rotatable such that during operation, the short part 12a rotates toward the floor side of the vehicle 3 and the long part 11a rotates toward the ceiling side of the vehicle 3.

[0026] Also, since each of the pair of grips 10 is rotatable with respect to the spoke 2, as shown in Fig. 1(b), during parking, the short part 12a is rotatable toward the rear side of the vehicle 3 and the long part 11a is rotatable toward the front side of the vehicle 3. That is, since each of the pair of grips 10 is rotatable with respect to the spoke 2, it is possible to make the short part 12a extend toward the rear side of the vehicle 3 with respect to the spoke 2, and it is possible to make the long part 11a extend toward the front side of the vehicle 3 with respect to the spoke 2.

[0027] Further, as shown in FIG. 1(c), the grip 10 disposed on the door 9 side of the vehicle 3 adjacent to the vehicle steering device 1 among the pair of grips 10 allows the driver to get on and off the vehicle 3 while holding the grip 10. When the driver gets on and off the vehicle 3, the long portion 11a extends toward the ceiling side of the vehicle 3, and the short portion 12a extends toward the floor side of the vehicle 3. At this time, the other grip 10 can be in a posture where the short portion 12a extends toward the rear side of the vehicle 3 and the long portion 11a extends toward the front side of the vehicle 3.

[0028] In the present embodiment, when the driver gets on and off the vehicle, the long portion 11a extends toward the ceiling side of the vehicle 3, and the short portion 12a extends toward the floor side of the vehicle 3. However, the configuration is not limited thereto. That is, so that the grip 10 does not interfere with the driver when getting on and off the vehicle 3, the long portion 11a may rotate not only toward the ceiling side of the vehicle 3 but also, for example, toward the front side of the vehicle 3 or in the direction of the front window between the front side and the ceiling side of the vehicle 3. However, in these configurations, it may be difficult for the driver to get on and off the vehicle 3 while holding the grip 10. Therefore, it is desirable that the long portion 11a extends toward the ceiling side of the vehicle 3 when the driver gets on and off the vehicle.

[0029] Further, when the steering position during driving is at the neutral position in the pair of grips 10, a gap is formed between the long portion 11a of one grip 10 and the long portion 11a of the other grip 10 in the pair of grips 10. For this reason, when each of the pair of grips 10 rotates, the pair of grips 10 can be prevented from interfering with the steering column 4 and the column cover 6 (see FIG. 3) that covers the lower part of the steering column 4.

[0030] As shown in FIGS. 1 and 2, a pair of first drive units 21 are provided corresponding to the pair of grips 10. Therefore, the pair of first drive units 21 rotate the pair of grips 10 so as to correspond one-to-one with the pair of grips 10.

[0031] The control unit 30 is electrically connected to the pair of first drive units 21 and controls the pair of first drive units 21 individually.

[0032] Specifically, as shown in FIGS. 1(a) and 2, when the vehicle 3 is manually operated, the control unit 30 controls the pair of first drive units 21 so that either the long portion 11a or the short portion 12a of the pair of grips 10 extends toward the ceiling side of the vehicle 3. As a result, when the vehicle 3 is manually operated, the long portion 11a of the pair of grips 10 extends toward the ceiling side of the vehicle 3, and the short portion 12a of the pair of grips 10 extends toward the floor side of the vehicle 3. Or, as shown in FIG. 1(a), the short portion 12a of the pair of grips 10 extends toward the ceiling side of the vehicle 3, and the long portion 11a of the pair of grips 10 extends toward the floor side of the vehicle 3.

[0033] Also, as shown in FIGS. 1(b) and 2, when the vehicle 3 is parked or automatically operated, the control unit 30 controls the pair of first drive units 21 so that the short portion 12a of the pair of grips 10 extends toward the rear side of the vehicle 3 and the long portion 11a of the pair of grips 10 extends toward the front side of the vehicle 3. As a result, when the vehicle 3 is parked or automatically operated, the short portion 12a of the pair of grips 10 extends toward the rear side of the vehicle 3, and the long portion 11a of the pair of grips 10 extends toward the front side of the vehicle 3.

[0034] Further, as shown in FIGS. 1(c) and 2, when the driver gets on or off the vehicle 3, the control unit 30 controls the first drive unit 21 on the door 9 side so that the long portion 11a of the grip 10 disposed on the door 9 side of the vehicle 3 adjacent to the vehicle steering device 1 extends toward the ceiling of the vehicle 3, and the short portion 12a of the grip 10 disposed on the door 9 side extends toward the floor of the vehicle 3. Thereby, when the driver gets on or off the vehicle 3, the long portion 11a of the grip 10 disposed on the door 9 side of the pair of grips 10 extends toward the ceiling of the vehicle 3, and the short portion 12a of the grip 10 extends toward the floor of the vehicle 3. Note that when the driver gets off the vehicle 3, the control unit 30 may maintain the posture in which the long portion 11a of the grip 10 disposed on the door 9 side extends toward the ceiling of the vehicle 3 and the short portion 12a extends toward the floor of the vehicle 3. In this case, the driver can get on the vehicle 3 while grasping the grip 10.

[0035] Further, as shown in FIGS. 1(d), 2, and 3, the vehicle steering device 1 may further include a table 50 and a second drive unit 22.

[0036] The table 50 is disposed below the vehicle steering device 1 and is movable in the longitudinal direction of the vehicle 3. The table 50 is stored in a storage space in the column cover 6 that covers the lower side of the steering column 4. Further, the table 50 moves closer to the driver's seat by being pulled out from the storage space in the column cover 6.

[0037] The table 50 further includes input means 51. The input means 51 is a touch pad, a touch panel, or a projection keyboard. In the case of a touch pad and a touch panel, they may be built into the table 50. Further, the projection keyboard may be realized by a projection device disposed on the spoke 2 or the like irradiating a keyboard image on the surface of the table 50 and a detection unit disposed on the spoke 2 or the like detecting the position of the driver's finger.

[0038] The second drive unit 22 drives the table 50 to move in the longitudinal direction of the vehicle 3. Specifically, when the second drive unit 22 drives the table 50 to move rearward of the vehicle 3 from the steering column 4, the table 50 is moved rearward of the vehicle 3 so as to protrude from the column cover 6 and be positioned immediately in front of the driver's seat. Further, the second drive unit 22 drives the table 50 to move forward of the vehicle 3 and stores the table 50 in the storage space within the column cover 6.

[0039] The control unit 30 controls the second drive unit 22 to move the table 50 forward of the vehicle 3 from the steering column 4 when the vehicle is parked or stopped. Further, the control unit 30 controls the second drive unit 22 to move the table 50 forward of the vehicle 3 and store it in the storage space within the column cover 6 during driving or boarding and alighting.

[0040] <Operation Example 1> Next, with reference to FIG. 4 and the like, an operation example of the vehicle steering device 1 will be described.

[0041] FIG. 4 is a flowchart showing the vehicle steering device 1 in which a pair of grips 10 can be automatically rotated.

[0042] First, the control unit 30 determines whether the vehicle 3 is in a driving state (S11). The determination as to whether it is in a driving state may be made, for example, by whether the control unit 30 acquires information indicating that the ignition switch is ON and the shift lever is in the D range (drive) from an ECU (Electronic Control Unit) or the like.

[0043] As shown in FIGS. 1(a), 2, and 4, when the control unit 30 determines that the vehicle 3 is in operation (Yes in S11), the control unit 30 controls the pair of first drive units 21 so that the long portions 11a or the short portions 12a of the pair of grips 10 extend toward the ceiling side of the vehicle 3 and the short portions 12a or the long portions 11a extend toward the floor side of the vehicle 3 (S14). Thereby, the pair of grips 10 rotate to a posture in which the long portions 11a or the short portions 12a extend toward the ceiling side of the vehicle 3 and the short portions 12a or the long portions 11a extend toward the floor side of the vehicle 3. The control unit 30 proceeds to step S18.

[0044] On the other hand, when the control unit 30 determines that the vehicle 3 is not in operation (No in S11), the control unit 30 determines whether the vehicle 3 is parked (S12). The determination of whether the vehicle is parked may be made, for example, by whether the control unit 30 acquires information indicating that the ignition switch is ON and the shift lever is in the P range (parking), or the door 9 is closed when the ignition switch is OFF, from an ECU or the like.

[0045] When the control unit 30 determines that the vehicle 3 is parked (Yes in S12), as shown in FIGS. 1(b), 2, and 4, the control unit 30 controls the pair of first drive units 21 so that the long portions 11a of the pair of grips 10 extend toward the front side of the vehicle 3 and the short portions 12a of the pair of grips 10 extend toward the rear side of the vehicle 3 (S15). Thereby, the pair of grips 10 rotate to a posture in which the long portions 11a extend toward the front side of the vehicle 3 and the short portions 12a extend toward the rear side of the vehicle 3.

[0046] Note that in step S12, the control unit 30 determines whether the vehicle 3 is parked, but is not limited thereto, and may determine whether the vehicle 3 is in autonomous driving.

[0047] Next, the control unit 30 determines whether the switch of the table 50 is ON (S16).

[0048] When the control unit 30 determines that the switch of the table 50 is OFF (No in S16), the control unit 30 returns the process to step S11.

[0049] When the control unit 30 determines that the switch of the table 50 is ON (Yes in S16), as shown in FIGS. 1(d), 2, and 4, the control unit 30 controls the second drive unit 22 so that the table 50 moves backward of the vehicle 3 (S17). As a result, the table 50 moves from the storage space in the column cover 6 to the rear side of the vehicle 3 and is pulled out immediately in front of the driver's seat. Then, the control unit 30 returns the process to step S11.

[0050] Also, in step S12 described above, when the control unit 30 determines that the vehicle 3 is not in the parked state (No in S12), since it means that the driver is getting on or off the vehicle 3, as shown in FIGS. 1(c), 2, and 4, the control unit 30 controls the pair of first drive units 21 so that the long portion 11a of the grip 10 on the door 9 side of the vehicle 3 adjacent to the vehicle steering device 1 extends toward the ceiling side of the vehicle 3 (S13). As a result, the grip 10 on the door 9 side rotates so that the long portion 11a extends toward the ceiling side of the vehicle 3 and the short portion 12a extends toward the floor side of the vehicle 3. The determination as to whether or not it is the time of getting on or off may be made, for example, by whether or not the control unit 30 acquires information indicating that the ignition switch is OFF and the door 9 is open from an ECU or the like.

[0051] Next, the control unit 30 determines whether or not the table 50 is stored in the storage space in the column cover 6 (S18).

[0052] When the control unit 30 determines that the table 50 is stored in the storage space in the column cover 6 (Yes in S18), the control unit 30 returns the process to step S11.

[0053] On the other hand, when the control unit 30 determines that the table 50 is not stored in the column cover 6 (No in S18), the control unit 30 controls the second drive unit 22 to store the table 50 in the storage space (S19). As a result, the table 50 moves toward the front side of the vehicle 3 and is stored in the storage space within the column cover 6. Then, the control unit 30 returns the process to step S11.

[0054] <Configuration and Function in Manual Operation> In the above, the case where the pair of grips 10 can be automatically rotated has been exemplified. However, with reference to FIG. 5, the case where the pair of grips 10 can be rotated manually with respect to the spoke 2 will be described.

[0055] FIG. 5 is a block diagram showing a vehicle steering device 1a in which a pair of grips 10 can be rotated manually.

[0056] In this case, the vehicle steering device 1a may further include a pair of position sensors 60, a table 50, a stopper 80, and a warning unit 70. Further, the vehicle steering device 1a may not include a pair of first drive units 21 and a second drive unit 22.

[0057] The pair of position sensors 60 are provided on the pair of grips 10 so as to correspond one-to-one. The pair of position sensors 60 detect the respective rotation positions of the pair of grips 10 so as to correspond one-to-one. Each of the pair of position sensors 60 outputs the respective rotation positions of the pair of grips 10 to the control unit 30a. The rotation position is indicated by the posture (position) of the pair of grips 10 with respect to the spoke 2, the rotation angle of the pair of grips 10, and the like.

[0058] The control unit 30a is electrically connected to the pair of position sensors 60 and acquires the respective rotation positions of the pair of grips 10 from the pair of position sensors 60.

[0059] Specifically, when the control unit 30a determines, based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60, that the long portions 11a or the short portions 12a of the pair of grips 10 are in a posture extending toward the ceiling side of the vehicle 3, the control unit 30a outputs a drivable signal. That is, since the long portions 11a of the pair of grips 10 extend toward the ceiling side or the floor side of the vehicle 3 and the short portions 12a of the pair of grips 10 extend toward the floor side or the ceiling side of the vehicle 3, the driver can hold the pair of grips 10 and drive the vehicle 3. In this case, the control unit 30a outputs a drivable signal.

[0060] Further, when the control unit 30a determines, based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60, that the short portions 12a of the pair of grips 10 are directed toward the rear side of the vehicle 3 and the long portions 11a extend toward the front side of the vehicle 3, the control unit 30a outputs a parking signal. That is, when the steering position during driving is at the neutral position, since the pair of grips 10 are in a posture tilted to be parallel to the horizontal direction, the driver does not drive the vehicle 3. In this case, the control unit 30a outputs a parking signal.

[0061] Further, based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60, when the control unit 30a determines that the long portion 11a of the grip 10 disposed on the door 9 side of the vehicle 3 adjacent to the vehicle steering device 1a among the pair of grips 10 is in a posture extending toward the ceiling direction of the vehicle 3 and the short portion 12a is in a posture extending toward the floor direction of the vehicle 3, the control unit 30a outputs a door unlocking permission signal. That is, when the driver wants to unlock the door 9 of the vehicle 3 adjacent to the vehicle steering device 1a, the driver manually adjusts the long portion 11a of the grip 10 disposed on the door 9 side to a posture extending toward the ceiling direction of the vehicle 3 and the short portion 12a of the grip 10 disposed on the door 9 side to a posture extending toward the floor direction of the vehicle 3. As a result, since the control unit 30a outputs a door unlocking permission signal, the driver can get out of the vehicle 3. Further, when the driver gets into the vehicle 3, the driver can sit on the driver's seat while grasping the long portion 11a of the grip 10 disposed on the door 9 side. Therefore, it becomes easier for the driver to get in and out of the vehicle 3.

[0062] The table 50 can be manually pulled out. The table 50 is disposed on the lower side of the steering wheel and is movable in the front-rear direction of the vehicle 3. The table 50 is stored in a storage space in a column cover 6 that covers the lower part of the steering column 4. Further, by pulling out the table 50 from within the column cover 6, the table 50 moves closer to the driver's seat. The table 50 further includes input means 51.

[0063] The stopper 80 is electrically connected to the control unit 30a and restricts the movement of the table 50. The stopper 80 is, for example, a solenoid stopper composed of an electromagnetic actuator or the like.

[0064] The stopper 80 can, under the control of the control unit 30a, restrict or release the movement of the table 50. When the stopper 80 is released, the stopper 80 outputs a signal indicating to the control unit 30a that it has been released. When the stopper 80 has not been released, the stopper 80 outputs a signal indicating to the control unit 30a that it has not been released.

[0065] When the control unit 30a outputs a parking signal, it releases the stopper 80 that restricts the backward movement of the table 50 of the vehicle 3. That is, when the vehicle 3 is parked, since the driver may pull out the table 50 stored in the storage space within the column cover 6, the control unit 30a drives and releases the stopper 80.

[0066] When the control unit 30a outputs a drivable signal or a door unlocking permission signal, if the stopper 80 is in a released state, it causes the warning unit 70 to output a warning prompting the storage of the table 50.

[0067] The warning unit 70 is an acoustic device mounted on the vehicle 3 or a display device mounted on the vehicle 3, etc. The warning is a warning prompting the storage of the table 50 by the sound output from the acoustic device, a warning prompting the storage of the table 50 by the display content displayed on the display device, etc.

[0068] <Operation Example 2> Next, with reference to FIG. 6 and the like, an operation example of the vehicle steering device 1a will be described.

[0069] FIG. 6 is a flowchart showing a vehicle steering device 1a in which a pair of grips 10 can be manually rotated.

[0070] First, as shown in FIGS. 5 and 6, based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60, the control unit 30a determines whether the long portions 11a or the short portions 12a of the pair of grips 10 extend toward the ceiling side of the vehicle 3, and whether the short portions 12a or the long portions 11a of the pair of grips 10 extend toward the floor side of the vehicle 3 (S21).

[0071] When the control unit 30a determines that the long portions 11a or the short portions 12a of the pair of grips 10 extend toward the ceiling side of the vehicle 3 and the short portions 12a or the long portions 11a of the pair of grips 10 extend toward the floor side of the vehicle 3 (Yes in S21), the control unit 30a outputs an operable signal to the ECU (S24). As a result, the vehicle 3 becomes operable. The control unit 30a proceeds to step S27 for processing.

[0072] On the other hand, when the control unit 30a determines that the long portions 11a or the short portions 12a of the pair of grips 10 do not extend toward the ceiling side of the vehicle 3 (No in S21), the control unit 30a determines whether the long portions 11a of the pair of grips 10 extend toward the front side of the vehicle 3 and the short portions 12a of the pair of grips 10 extend toward the rear side of the vehicle 3 (S22).

[0073] When the control unit 30a determines that the long portions 11a of the pair of grips 10 extend toward the front side of the vehicle 3 and the short portions 12a of the pair of grips 10 extend toward the rear side of the vehicle 3 (Yes in S22), the control unit 30a outputs a parking signal (S25).

[0074] Next, when outputting the parking signal, the control unit 30a controls to release the stopper 80 that restricts the backward movement of the table 50 of the vehicle 3 (S26). Then, the control unit 30a returns the process to step S21.

[0075] Also, in step S22 described above, when the control unit 30a determines that the long portions 11a of the pair of grips 10 do not extend toward the front side of the vehicle 3 and the short portions 12a of the pair of grips 10 do not extend toward the rear side of the vehicle 3 (No in S22), since it is neither the state of (a) nor the state of (b) in FIG. 1, it is determined to be the state of (c) in FIG. 1, and the control unit 30a outputs a door unlocking permission signal to the ECU (S23).

[0076] Next, the control unit 30a determines whether the stopper 80 has been released (S27).

[0077] When the control unit 30a determines that the stopper 80 has not been released (No in S27), the process returns to step S21. That is, if the stopper 80 has not been released, in order to indicate that the table 50 is stored in the storage space within the column cover 6, the long portions 11a or the short portions 12a of the pair of grips 10 extend toward the ceiling side of the vehicle 3, and the short portions 12a or the long portions 11a of the pair of grips 10 extend toward the floor side of the vehicle 3.

[0078] When the control unit 30a determines that the stopper 80 has been released (Yes in S27), the control unit 30a causes the warning unit 70 to output a warning prompting the storage of the table 50 (S28). Then, the control unit 30a returns the process to step S21.

[0079] In addition, in the present embodiment, a configuration in which the vehicle steering device 1a includes the table 50 is illustrated, but a configuration in which the vehicle steering device 1a does not have the table 50 may also be possible.

[0080] (Modification of the embodiment) Next, with reference to FIGS. 7 and 8, the vehicle steering device 1b of this modification will be described.

[0081] FIG. 7 is a perspective view showing a vehicle steering device 1b in which the steering 100 can be automatically rotated. FIG. 7(a) shows the case where the steering position during driving is at the neutral position. FIG. 7(b) shows the case where the pair of steerings 100 are tilted and in a horizontal posture. FIG. 7(c) shows the case where the steering 100 is in a vertical posture such that the connecting portion 13 is located above the spoke 2. FIG. 7(d) shows the case where the steering 100 is tilted and in a horizontal posture, and the table 50 is pulled out. FIG. 8 is a block diagram showing the vehicle steering device 1b in which the steering 100 can be automatically rotated.

[0082] This modified example is different from the embodiment in that one of the ends of the pair of grips 10 is integrally connected to each other. Since the configuration of the vehicle steering device 1b in this modified example is the same as the configuration shown in the embodiment, the same reference numerals are given to the configuration of the vehicle steering device 1b in this modified example, and the description thereof will be omitted as appropriate.

[0083] <Configuration and Function in Automatic Mode> In this modified example, the end portion (long portion 11a) of one of the pair of grips and the end portion (long portion 11a) of the other grip are connected to each other by the connecting portion 13, thereby forming a semi-circular grip. In this modified example, the pair of grips (semi-circular grips) connected by the connecting portion 13 are collectively referred to as the steering 100.

[0084] As shown in FIGS. 7 and 8, the vehicle steering device 1b of this modified example includes a spoke 2, a steering 100, a third drive unit 23, and a control unit 30b.

[0085] The end portion of the spoke 2 in the left direction is connected to the end portion of the steering 100 in the left direction, and the end portion of the spoke 2 in the right direction is connected to the end portion of the steering 100 in the right direction.

[0086] The steering 100 is rotatable with respect to the spoke 2. The steering 100 is automatically rotatable with respect to the spoke 2 by the third drive unit 23 controlled by the control unit 30b. Since the pair of grips 10 are integrated by the connecting portion 13, the steering 100 rotates integrally with respect to the spoke 2.

[0087] Further, the steering 100 has a connecting portion 13 corresponding to the above-described long portion 11a and the above-described short portion 12a.

[0088] As shown in Fig. 7(a), during driving, the short portion 12a of the steering wheel 100 can rotate toward the ceiling side of the vehicle 3, and the connecting portion 13 can rotate toward the floor side of the vehicle 3. That is, since the steering wheel 100 is rotatable with respect to the spoke 2, it is possible to arrange the connecting portion 13 in a posture on the floor side of the vehicle 3 with respect to the spoke 2, and it is possible to extend the short portion 12a in a posture toward the ceiling side of the vehicle 3 with respect to the spoke 2. Note that the short portion 12a of the steering wheel 100 may also be rotatable toward the floor side of the vehicle 3 and the connecting portion 13 may be rotatable toward the ceiling side of the vehicle 3 during driving.

[0089] Also, since the steering wheel 100 is rotatable with respect to the spoke 2, as shown in Fig. 7(b), during parking, the short portion 12a can rotate toward the rear side of the vehicle 3, and the long portion 11a can rotate toward the front side of the vehicle 3. That is, since the steering wheel 100 is rotatable with respect to the spoke 2, it is possible to extend the short portion 12a in a posture toward the rear side of the vehicle 3 with respect to the spoke 2, and it is possible to arrange the connecting portion 13 in a posture on the front side of the vehicle 3 with respect to the spoke 2.

[0090] Also, as shown in Fig. 7(c), so that the driver can get in and out of the vehicle 3 while grasping the steering wheel 100, during getting in and out of the vehicle 3 by the driver, the connecting portion 13 can be arranged in a posture on the ceiling side of the vehicle 3 with respect to the spoke 2, and the short portion 12a can be extended in a posture toward the floor side of the vehicle 3.

[0091] In addition, in this modified example, when the driver gets on and off the vehicle, the connecting portion 13 is in a posture arranged on the ceiling side of the vehicle 3 with respect to the spoke 2, and the short portion 12a extends toward the floor side of the vehicle 3. However, the present invention is not limited to this configuration. That is, so that the steering 100 does not get in the way when the driver gets on and off the vehicle 3, the connecting portion 13 may be arranged not only on the ceiling side of the vehicle 3 but also, for example, on the front side of the vehicle 3 or in the direction of the front window between the front side and the ceiling side of the vehicle 3. However, in these configurations, it may be difficult for the driver to get on and off the vehicle 3 while grasping the steering 100. Therefore, it is desirable that the connecting portion 13 be in a posture arranged on the ceiling side of the vehicle 3 when the driver gets on and off the vehicle.

[0092] The third drive unit 23 rotates the steering 100 by driving.

[0093] The control unit 30b is electrically connected to the third drive unit 23 and controls the third drive unit 23.

[0094] Specifically, as shown in FIGS. 7(a) and 8, the control unit 30b controls the third drive unit 23 so that either the connecting portion 13 or the short portion 12a of the steering 100 is in a posture arranged on the ceiling side of the vehicle 3 during the operation of the vehicle 3. Thereby, during the operation of the vehicle 3, the connecting portion 13 of the steering 100 is in a posture arranged on the ceiling side of the vehicle 3 with respect to the spoke 2, and the short portion 12a of the steering 100 extends toward the floor side of the vehicle 3. Or, as shown in FIG. 7(a), the short portion 12a of the steering 100 extends toward the ceiling side of the vehicle 3, and the connecting portion 13 of the steering 100 is in a posture arranged on the floor side of the vehicle 3 with respect to the spoke 2.

[0095] Further, as shown in FIG. 7(b) and FIG. 8, when the vehicle 3 is parked or in autonomous driving, the control unit 30b controls the third drive unit 23 so that the short portion 12a of the steering 100 extends toward the rear side of the vehicle 3 and the connecting portion 13 of the steering 100 is disposed on the front side of the vehicle 3 with respect to the spoke 2. Thereby, when the vehicle 3 is parked, the short portion 12a of the steering 100 extends toward the rear side of the vehicle 3, and the connecting portion 13 of the steering 100 is disposed on the front side of the vehicle 3.

[0096] Further, as shown in FIG. 7(c) and FIG. 8, when the driver gets on or off the vehicle 3, the control unit 30b controls the third drive unit 23 so that the connecting portion 13 of the steering 100 is disposed on the ceiling side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering 100 extends toward the floor side of the vehicle 3. Thereby, when the driver gets on or off the vehicle 3, the connecting portion 13 of the steering 100 is disposed on the ceiling side of the vehicle 3 with respect to the spoke 2, and the short portion 12a of the steering 100 extends toward the floor side of the vehicle 3.

[0097] Note that, when the connecting portion 13 of the steering 100 is disposed on the ceiling side of the vehicle 3 during driving, in order to distinguish from the case where the connecting portion 13 of the steering 100 is disposed on the ceiling side of the vehicle 3 when the driver gets on or off, the control unit 30b controls the third drive unit 23 so that the position of the connecting portion 13 differs depending on whether it is during driving or getting on or off. That is, the control unit 30b controls the third drive unit 23 so that the connecting portion 13 is disposed on the ceiling side near the front window during driving, and controls the third drive unit 23 so that the connecting portion 13 is disposed on the ceiling side near the seat when getting on or off.

[0098] Further, similar to the above embodiment, the vehicle steering device 1b may further include a table 50 and a fourth drive unit 24.

[0099] As shown in FIG. 7(d), the table 50 is disposed on the lower side of the vehicle steering device 1b and is movable in the longitudinal direction of the vehicle 3. The table 50 is stored in a storage space within a column cover 6 (see FIG. 3) that covers the lower part of the steering column 4. Further, the table 50 moves closer to the driver's seat by being pulled out from the storage space within the column cover 6.

[0100] The table 50 further includes an input means 51. The input means 51 is a touch pad, a touch panel, or a projected keyboard.

[0101] The fourth drive unit 24 drives the table 50 to move in the longitudinal direction of the vehicle 3. Specifically, when the fourth drive unit 24 drives the table 50 to move rearward of the vehicle 3 from the steering column 4, the table 50 is moved rearward of the vehicle 3 so as to protrude from the column cover 6 and be positioned immediately in front of the driver's seat. Further, the fourth drive unit 24 drives the table 50 to move forward of the vehicle 3 and stores the table 50 in the storage space within the column cover 6.

[0102] The control unit 30b controls the fourth drive unit 24 to move the table 50 forward of the vehicle 3 from the steering column 4 during parking. Further, the control unit 30b controls the fourth drive unit 24 to move the table 50 forward of the vehicle 3 and store it in the storage space within the column cover 6 during driving or boarding and alighting.

[0103] <Operation Example 1> Next, with reference to FIG. 9, an operation example of the vehicle steering device 1b will be described.

[0104] FIG. 9 is a flowchart showing a vehicle steering device 1b in which the steering 100 can be automatically rotated. Here, the case where the connection portion 13 of the steering 100 is disposed on the floor side of the vehicle 3 during driving will be described.

[0105] First, the control unit 30b determines whether the vehicle 3 is in the driving state (S31).

[0106] When the control unit 30b determines that the vehicle 3 is in operation (Yes in S31), the control unit 30b controls the third drive unit 23 so that the connection portion 13 of the steering 100 is disposed on the floor side of the vehicle 3 with respect to the spoke 2 and the short portion 12a extends toward the ceiling side of the vehicle 3 (S34). Thereby, the steering 100 rotates to a posture in which the connection portion 13 is disposed on the floor side of the vehicle 3 with respect to the spoke 2, and the short portion 12a extends toward the ceiling side of the vehicle 3. The control unit 30b proceeds to step S38.

[0107] On the other hand, when the control unit 30b determines that the vehicle 3 is not in operation (No in S31), the control unit 30b determines whether the vehicle 3 is in a parked state (S32).

[0108] When the control unit 30b determines that the vehicle 3 is in a parked state (Yes in S32), as shown in FIGS. 7(b), 8, and 9, the control unit 30b controls the third drive unit 23 so that the connection portion 13 of the steering 100 is disposed on the front side of the vehicle 3 with respect to the spoke 2 and the short portion 12a extends toward the rear side of the vehicle 3 (S35). Thereby, the steering 100 rotates to a posture in which the connection portion 13 is disposed on the front side of the vehicle 3 with respect to the spoke 2, and the short portion 12a extends toward the rear side of the vehicle 3.

[0109] Note that in step S32, the control unit 30b determines whether the vehicle 3 is in a parked state, but not limited thereto, the control unit 30b may determine whether the vehicle 3 is in an autonomous driving state.

[0110] Next, the control unit 30b determines whether the switch of the table 50 is ON (S36).

[0111] When the control unit 30b determines that the switch of the table 50 is OFF (No in S36), the control unit 30b returns the process to step S31.

[0112] When the control unit 30b determines that the switch of the table 50 is ON (Yes in S36), as shown in FIGS. 7(d), 8, and 9, the control unit 30b controls the fourth drive unit 24 so that the table 50 moves backward in the vehicle 3 (S37). As a result, the table 50 moves from within the column cover 6 to the rear side of the vehicle 3 and is pulled out immediately in front of the driver's seat. Then, the control unit 30b returns the process to step S31.

[0113] Also, in step S32 described above, when the control unit 30b determines that the vehicle 3 is not in a parked state (No in S32), since it means that the driver is getting on or off the vehicle 3, as shown in FIGS. 7(c), 8, and 9, the control unit 30b controls the third drive unit 23 so that the connecting portion 13 of the steering 100 is disposed on the ceiling side of the vehicle 3 with respect to the spoke 2 (S33). As a result, the steering 100 rotates so that the connecting portion 13 is disposed on the ceiling side of the vehicle 3 with respect to the spoke 2, and the short portion 12a extends toward the floor side of the vehicle 3.

[0114] Next, the control unit 30b determines whether the table 50 is stored in the storage space within the column cover 6 (S38).

[0115] When the control unit 30b determines that the table 50 is stored in the storage space within the column cover 6 (Yes in S38), the process returns to step S31.

[0116] On the other hand, when the control unit 30b determines that the table 50 is not stored in the storage space within the column cover 6 (No in S38), the fourth drive unit 24 is controlled to store the table 50 (S39). As a result, the table 50 moves to the front side of the vehicle 3 and is stored in the storage space within the column cover 6. Then, the control unit 30b returns the process to step S31.

[0117] <Configuration and Function in Manual Mode> In the above, the case where the steering 100 can be automatically rotated has been exemplified. However, with reference to FIG. 10, the case where the steering 100 can be rotated manually with respect to the spoke 2 will be described.

[0118] FIG. 10 is a block diagram showing a vehicle steering device 1c in which the steering 100 can be manually rotated.

[0119] In this case, the vehicle steering device 1c may further include a position sensor 60, a table 50, a stopper 80, and a warning unit 70. Also, the vehicle steering device 1c may not include a third drive unit 23 and a fourth drive unit 24.

[0120] The position sensor 60 detects the rotation position of the steering 100. The position sensor 60 outputs the rotation position of the steering 100 to the control unit 30c.

[0121] The control unit 30c is electrically connected to the position sensor 60 and acquires each rotation position of the steering 100.

[0122] Specifically, when the control unit 30c determines that the connection part 13 or the short part 12a in the steering 100 is in a posture arranged on the ceiling direction side of the vehicle 3 based on each rotation position of the steering 100 detected by the position sensor 60, it outputs an operable signal. That is, since the connection part 13 in the steering 100 is arranged on the ceiling direction side or the floor direction side of the vehicle 3, and the short part 12a in the steering 100 extends in the floor direction side or the ceiling direction side of the vehicle 3, the driver can grasp the steering 100 and drive the vehicle 3. In this case, the control unit 30c outputs an operable signal.

[0123] Further, based on each rotation position of the steering 100 detected by the position sensor 60, when the control unit 30c determines that the short portion 12a of the steering 100 faces the rear direction side of the vehicle 3 and the connecting portion 13 is arranged on the front direction side of the vehicle 3 with respect to the spoke 2, the control unit 30c outputs a parking signal. That is, when the steering position during driving is at the neutral position, the steering 100 is in a tilted posture parallel to the horizontal direction, so the driver does not drive the vehicle 3. In this case, the control unit 30c outputs a parking signal.

[0124] Further, based on each rotation position of the steering 100 detected by the position sensor 60, when the control unit 30c determines that the connecting portion 13 of the steering 100 is arranged on the ceiling direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a extends in the floor direction side of the vehicle 3, the control unit 30c outputs a door unlocking permission signal. That is, when the driver wants to unlock the door 9 of the vehicle 3 adjacent to the vehicle steering device 1, the driver manually adjusts the steering 100 so that the connecting portion 13 is arranged on the ceiling direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering 100 extends in the floor direction side of the vehicle 3. As a result, since the control unit 30c outputs a door unlocking permission signal, the driver can get out of the vehicle 3. In addition, when the driver gets into the vehicle 3, the driver can sit on the driver's seat while grasping the long portion 11a of the steering 100. Therefore, it is easier for the driver to get in and out of the vehicle 3.

[0125] Note that during driving, when the connecting portion 13 of the steering 100 is arranged on the ceiling direction side of the vehicle 3, in order to distinguish it from the case where the connecting portion 13 of the steering 100 is arranged on the ceiling direction side of the vehicle 3 when the driver gets in and out, the control unit 30c determines whether it is during driving or getting in and out based on the position of the connecting portion 13 by the position sensor 60. That is, during driving, the connecting portion 13 is arranged on the ceiling direction side near the front window, and during getting in and out, the connecting portion 13 is arranged on the ceiling direction side near the seat, and it can be positioned by, for example, a regulating mechanism. Thereby, the control unit 30c can determine whether it is during driving or getting in and out from the output of the position sensor 60.

[0126] Table 50 can be manually pulled out. Table 50 is disposed on the lower side of the steering wheel and is movable in the longitudinal direction of the vehicle 3.

[0127] The stopper 80 is electrically connected to the control unit 30c and restricts the movement of the table 50. The stopper 80 can, under the control of the control unit 30c, restrict or release the movement of the table 50. When the stopper 80 is released, the stopper 80 outputs a signal indicating to the control unit 30c that it is released. Also, when the stopper 80 is not released, the stopper 80 outputs a signal indicating to the control unit 30c that it is not released.

[0128] When the control unit 30c outputs a parking / stopping signal, it releases the stopper 80 that restricts the backward movement of the table 50 of the vehicle 3. That is, when the vehicle 3 is parked, since the driver may pull out the table 50 stored in the storage space within the column cover 6, the control unit 30c releases the stopper 80.

[0129] When the control unit 30c outputs an operable signal or a door unlocking permission signal, if the stopper 80 is in a released state, it causes the warning unit 70 to output a warning prompting the storage of the table 50.

[0130] <Operation Example 2> Next, with reference to FIG. 11, an operation example of the vehicle steering device 1c will be described.

[0131] FIG. 11 is a flowchart showing a vehicle steering device 1c in which the steering 100 can be manually rotated. Here, the case where the connecting portion 13 of the steering 100 is disposed on the floor side of the vehicle 3 during driving will be described.

[0132] First, based on the rotation position of the steering wheel 100 detected by the position sensor 60, the control unit 30c determines whether the connecting portion 13 of the steering wheel 100 is disposed on the floor direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering wheel 100 extends toward the ceiling direction side of the vehicle 3 (S41).

[0133] When the control unit 30c determines that the connecting portion 13 of the steering wheel 100 is disposed on the floor direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering wheel 100 extends toward the ceiling direction side of the vehicle 3 (Yes in S41), the control unit 30c outputs an operable signal to the ECU (S44). Thereby, the vehicle 3 becomes operable. The control unit 30c proceeds to step S47 for processing.

[0134] On the other hand, when the control unit 30c determines that the connecting portion 13 of the steering wheel 100 is not disposed on the floor direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering wheel 100 does not extend toward the ceiling direction side of the vehicle 3 (No in S41), the control unit 30c determines whether the connecting portion 13 of the steering wheel 100 is disposed on the front direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering wheel 100 extends toward the rear direction side of the vehicle 3 (S42).

[0135] When the control unit 30c determines that the connecting portion 13 of the steering wheel 100 is disposed on the front direction side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering wheel 100 extends toward the rear direction side of the vehicle 3 (Yes in S42), the control unit 30c outputs a parking signal (S45).

[0136] Next, when the control unit 30c outputs the parking signal, it controls to release the stopper 80 that restricts the movement of the table 50 in the rear direction of the vehicle 3 (S46). Then, the control unit 30c returns the process to step S41.

[0137] Also, in the above-mentioned step S42, when the control unit 30c determines that the connecting portion 13 of the steering 100 is not arranged on the front side of the vehicle 3 with respect to the spoke 2 and the short portion 12a of the steering 100 does not extend toward the rear side of the vehicle 3 (No in S42), since it is neither the state of Fig. 7(a) nor Fig. 7(b), it is determined to be the state of Fig. 7(c), and the control unit 30c outputs a door unlocking permission signal to the ECU (S43).

[0138] Next, the control unit 30c determines whether the stopper 80 is released (S47).

[0139] When the control unit 30c determines that the stopper 80 is not released (No in S47), the process returns to step S41.

[0140] When the control unit 30c determines that the stopper 80 is released (Yes in S47), the control unit 30c causes the warning unit 70 to output a warning prompting the storage of the table 50 (S48). Then, the control unit 30c returns the process to step S41.

[0141] Note that in the modification of this embodiment, although the configuration in which the vehicle steering device 1c includes the table 50 is illustrated, the vehicle steering device 1c may not have the table 50.

[0142] (Other modifications) For example, in the above embodiment, the first part and the second part may have the same length. In this case, for example, the short portion 12a may be referred to as the first part or the second part, and the long portion 11a may be referred to as the second part or the first part.

[0143] Also, in the above embodiment, the vehicle steering device 1d may have the configuration as shown in Fig. 12. Fig. 12 is a block diagram showing the vehicle steering device 1d of another modification. Note that in the configuration of Fig. 12, since the vehicle steering device 1d does not include the second drive unit 22 and the stopper 80, the vehicle steering device 1d does not have the table 50.

[0144] As shown in FIG. 12, the vehicle steering device 1d further includes a detection unit 90 that detects the connection between the tongue of the seat belt provided in the vehicle 3 and the buckle provided in the driver's seat. When the detection unit 90 detects the connection between the tongue and the buckle, it outputs a signal indicating that the tongue and the buckle are connected to the control unit 30. In this case, the control unit 30 controls the pair of first drive units 21 so that either the long portion 11a or the short portion 12a of the pair of grips 10 shown in FIG. 1(a) extends toward the ceiling direction side of the vehicle 3. Further, the control unit 30b controls the third drive unit 23 so that the connection portion 13 of the steering wheel 100 shown in FIG. 7(a) is disposed on the floor direction side of the vehicle 3 rather than the spoke 2.

[0145] Further, when the detection unit 90 detects that the connection between the tongue and the buckle has been released, it outputs a signal indicating that the connection between the tongue and the buckle has been released to the control unit 30. In this case, the control unit 30 controls the pair of first drive units 21 so that the long portion 11a of the pair of grips 10 extends toward the front direction side of the vehicle 3 and the short portion 12a of the pair of grips 10 extends toward the rear direction side of the vehicle as shown in FIG. 1(b). Further, the control unit 30b controls the third drive unit 23 so that the connection portion 13 of the steering wheel 100 shown in FIG. 7(b) is disposed on the front direction side of the vehicle rather than the spoke 2.

[0146] Also, in the above embodiment, the vehicle steering device 1e may have a configuration as shown in FIG. 13. FIG. 13 is another block diagram showing the vehicle steering device 1e of another modification. In the configuration of FIG. 13, since the vehicle steering device 1e does not include the second drive unit 22 and the stopper 80, the vehicle steering device 1e does not have the table 50.

[0147] As shown in FIG. 13, the vehicle steering device 1d further includes an operation input unit 91 that can be operated and input by the driver. The operation input unit 91 is, for example, a capacitive touch pad. The operation input unit 91 is provided on the end surface of each short portion 12a of the pair of grips 10. Note that the operation input unit 91 may be provided on only one of the pair of grips 10, or may be provided on both.

[0148] (Function and effect) Next, the function and effect of the vehicle steering devices 1, 1a, 1b, 1c, 1d, 1e in the above-described embodiment, the modified example of the embodiment, and other modified examples will be described.

[0149] The vehicle steering devices 1, 1a, 1b, 1c, 1d, 1e of Technology 1 in the present embodiment etc. include the spoke 2 of the steering wheel and a pair of grips 10 that are arc-shaped or linear and are arranged on the left and right of the spoke 2, and the pair of grips 10 has a configuration that is rotatable with respect to the spoke 2.

[0150] According to this, since the pair of grips 10 can be rotated with respect to the spoke 2, by rotating the pair of grips 10, the space in front of the driver sitting in the driver's seat can be widened. For this reason, unlike the vehicle steering device of Patent Document 1 described above, it is not necessary to arrange a lateral movement mechanism for laterally moving the steering wheel from the position in front of the driver's seat to the position in front of the passenger seat.

[0151] Therefore, it is possible to simplify the structure around the steering wheel.

[0152] Also, the vehicle steering devices 1, 1a, 1d, 1e of Technology 2 in the present embodiment etc. are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 1. In this case, each of the pair of grips 10 is separated so as to be independently rotatable on the left and right of the spoke 2.

[0153] According to this, since the postures of the pair of grips 10 can be freely adjusted left and right, the width of the space in front of the driver sitting in the driver's seat can be adjusted.

[0154] Also, the vehicle steering devices 1, 1a, 1d, 1e of Technology 3 in the present embodiment etc. are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 1 or 2. In this case, in the pair of grips 10, when the steering position during driving of the vehicle 3 by the driver is at the neutral position, the length of the first portion extending toward the ceiling side of the vehicle 3 with respect to the spoke 2 and the length of the second portion extending toward the floor side of the vehicle 3 with respect to the spoke 2 are different.

[0155] According to this, since the length of the first portion and the length of the second portion are different, for example, if the short portion 12a is arranged to extend toward the driver side, the long portion 11a can be arranged on the side opposite to the driver side, so that the space between the driver and the steering wheel can be widened. In particular, by arranging the short portion 12a to extend toward the driver side during parking, it becomes easier for the driver to get in and out of the vehicle 3.

[0156] Also, the vehicle steering devices 1, 1a, 1d, 1e of Technology 4 in the present embodiment etc. are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 3. In this case, when the longer one of the first portion and the second portion is the long portion 11a and the shorter one is the short portion 12a, the pair of grips 10 can rotate such that the short portion 12a moves toward the rear direction side of the vehicle 3 and the long portion 11a moves toward the front direction side of the vehicle 3 when the vehicle 3 is parked.

[0157] According to this, by rotating the pair of grips 10 so that the long portion 11a is arranged toward the front direction side of the vehicle 3 and the short portion 12a is arranged toward the driver side during parking, the foot space of the driver can be widened.

[0158] In addition, the vehicle steering devices 1, 1a, 1d, 1e of Technology 5 in the present embodiment and the like are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 4. In this case, the pair of grips 10 are rotatable independently of each other. Further, the grip 10 disposed on the door 9 side of the vehicle 3 adjacent to the vehicle steering devices 1, 1a, 1d, 1e has a posture in which the long portion 11a extends toward the ceiling direction of the vehicle 3 and the short portion 12a extends toward the floor direction of the vehicle 3 when the driver gets on and off the vehicle 3.

[0159] Normally, since a steering wheel or the like is arranged at the driver's seat of a vehicle, the space in front is narrower than that at the passenger seat or the like. For this reason, it is more difficult for the driver to get on and off than at other seats.

[0160] However, according to the present embodiment and the like, while gripping the long portion 11a of the grip disposed on the door 9 side of the vehicle 3, the driver can get off from the driver's seat of the vehicle 3 or get on the driver's seat of the vehicle 3. For this reason, it becomes easier for the driver to get on and off with respect to the driver's seat.

[0161] Also, the vehicle steering devices 1, 1d, 1e of Technology 6 in the present embodiment and the like are the vehicle steering devices 1, 1d, 1e described in Technology 5. In this case, further, it includes a pair of grips 10, a pair of first drive units 21 for rotating the pair of grips 10, and a control unit 30 electrically connected to the pair of first drive units 21. Also, when the steering position during the operation of the vehicle 3 is at the neutral position, the length of the first portion extending toward the ceiling direction of the vehicle 3 with respect to the spoke 2 and the length of the second portion extending toward the floor direction of the vehicle 3 with respect to the spoke 2 of the pair of grips 10 are different. When the longer one of the first portion and the second portion is defined as the long portion 11a and the shorter one is defined as the short portion 12a, the pair of grips 10 can rotate such that the short portion 12a faces the rear direction of the vehicle 3 and the long portion 11a faces the front direction of the vehicle 3 when the vehicle 3 is parked. And the control unit 30 controls the pair of first drive units 21 so that either the long portion 11a or the short portion 12a of the pair of grips 10 extends toward the ceiling direction of the vehicle 3 during manual driving, controls the pair of first drive units 21 so that the short portion 12a of the pair of grips 10 extends toward the rear direction of the vehicle 3 and the long portion 11a extends toward the front direction of the vehicle 3 during parking or automatic driving, and controls the pair of first drive units 21 so that the long portion 11a of the grip 10 arranged on the door 9 side of the vehicle 3 adjacent to the vehicle steering devices 1, 1d, 1e extends toward the ceiling direction of the vehicle 3 and the short portion 12a of the grip 10 arranged on the door 9 side extends toward the floor direction of the vehicle 3 during boarding and alighting.

[0162] According to this, the rotation position of the grip 10 automatically changes according to the state of the vehicle 3 such as during driving, parking, and boarding and alighting, so that special operations such as rotating the pair of grips 10 by the driver are not required. Therefore, the convenience of the driver can be improved.

[0163] Also, the vehicle steering devices 1, 1a, 1d, 1e of Technology 7 in this embodiment and the like are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 6. In this case, the vehicle steering devices 1, 1a, 1d, 1e further include a table 50 stored in a storage space within a column cover 6 that covers the lower part of the steering column 4, and a second drive unit 22 that drives the table 50 to move rearward from the steering column 4 toward the vehicle 3 and also drives it to move forward toward the vehicle 3 and store it in the storage space within the column cover 6. Then, the control units 30, 30a control the second drive unit 22 to move the table 50 rearward from the steering column 4 toward the vehicle 3 during parking, and control the second drive unit 22 to move the table 50 forward toward the vehicle 3 and store it in the storage space within the column cover 6 during driving or getting in and out of the vehicle.

[0164] According to this, when the vehicle 3 is parked, the table 50 is automatically pulled out in front of the driver's eyes. Therefore, the driver can perform work on the table 50 without performing any special operations. As a result, the convenience of the driver can be improved.

[0165] Also, the vehicle steering devices 1a, 1d, 1e of Technology 8 in the present embodiment and the like are the vehicle steering devices 1a, 1d, 1e described in Technology 5. In this case, the vehicle steering devices 1a, 1d, 1e further include a pair of position sensors 60 that detect the respective rotation positions of the pair of grips 10, and control units 30, 30a that are electrically connected to the position sensors 60. Also, the pair of grips 10 are each manually rotatable. And the control units 30, 30a are electrically connected to the pair of position sensors 60, and when it is determined based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60 that the long portions 11a or the short portions 12a in the pair of grips 10 are in a posture extending toward the ceiling direction side of the vehicle 3, an operable signal is output. When it is determined based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60 that the short portions 12a in the pair of grips 10 face the rear direction side of the vehicle 3 and the long portions 11a in the pair of grips 10 extend toward the front direction side of the vehicle 3, a parking signal is output. When it is determined based on the respective rotation positions of the pair of grips 10 detected by the pair of position sensors 60 that the long portion 11a of the grip disposed on the door 9 side faces the ceiling direction side of the vehicle 3 and the short portion 12a extends toward the floor direction side of the vehicle 3, a door unlocking permission signal is output.

[0166] According to this, since respective signals are output to the ECU according to the positions of the grips, the ECU can perform appropriate vehicle 3 control according to these signals.

[0167] Also, the vehicle steering devices 1a, 1d, 1e of Technology 9 in the present embodiment and the like are the vehicle steering devices 1, 1a, 1d, 1e described in Technology 8. In this case, the vehicle steering devices 1a, 1d, 1e further include a table 50 that is stored in a storage space in a column cover 6 that covers the lower part of the steering column 4 and can be manually pulled out, and a stopper 80 that is electrically connected to the control units 30, 30a and restricts the movement of the table 50. And the control units 30, 30a release the stopper 80 when a parking signal is output.

[0168] According to this, since the drawer of the table 50 is permitted only during parking and stopping, it is possible to suppress a decrease in safety during the running of the vehicle 3, and it is possible to achieve both the improvement in convenience that the table 50 can be used only during parking and stopping.

[0169] Also, the vehicle steering devices 1a, 1d, 1e of the technology 10 in the present embodiment etc. are the vehicle steering devices 1a, 1d, 1e described in the technology 9. In this case, when the control units 30, 30a output a drivable signal or a door unlocking permission signal, if the stopper 80 is in a released state, a warning for prompting to store the table 50 is output to the warning unit 70.

[0170] According to this, at the start of driving and at the start of boarding and alighting, when the table 50 is pulled out from the storage space in the column cover 6, a warning can be issued to the driver. For this reason, it is possible to prompt the driver to store the table 50 in the storage space in the column cover 6. As a result, it is possible to suppress a decrease in safety during the running of the vehicle 3 and during the boarding and alighting of the driver with respect to the vehicle 3.

[0171] Also, the vehicle steering devices 1b, 1c, 1d, 1e of the technology 11 in the present embodiment etc. are the vehicle steering devices 1b, 1c, 1d, 1e described in the technology 1. In this case, one pair of grips 10 constitutes a steering 100 in which one of the ends of the grips 10 is integrally connected to each other. And when the connected part of the one pair of grips 10 is made into the connection part 13, the steering 100 is rotatable so that the connection part 13 may be located on the front direction side of the vehicle 3 during parking and stopping of the vehicle 3.

[0172] According to this, during parking and stopping, by rotating the steering 100 so that the connection part 13 is arranged on the front direction side of the vehicle 3 and the short part 12a on the side opposite to the connection part 13 is arranged on the driver side, the foot space of the driver can be widened.

[0173] In addition, the vehicle steering devices 1b, 1c, 1d, and 1e of Technology 12 in the present embodiment and the like are the vehicle steering devices 1b, 1c, 1d, and 1e described in Technology 11. In this case, for the steering wheel 100, when the driver gets in and out of the vehicle 3, the connection portion 13 is arranged on the ceiling side of the vehicle 3 rather than the spoke 2.

[0174] Normally, since a steering wheel or the like is arranged in the driver's seat of the vehicle 3, the space in the front is narrower than that in the passenger seat or the like. For this reason, it is more difficult for the driver to get in and out compared to other seats.

[0175] However, according to the present embodiment and the like, the driver can get out of the driver's seat of the vehicle 3 or get into the driver's seat of the vehicle 3 while grasping the connection portion 13 of the vehicle 3. For this reason, it becomes easier for the driver to get in and out of the driver's seat.

[0176] In addition, the vehicle steering devices 1b, 1d, and 1e of Technology 13 in the present embodiment and the like are the vehicle steering devices 1b, 1d, and 1e described in Technology 12. In this case, the vehicle steering devices 1b, 1d, and 1e further include a third drive unit 23 that rotates the steering wheel 100, and control units 30 and 30b that are electrically connected to the third drive unit 23. Then, the control units 30 and 30b control the third drive unit 23 so that the connection portion 13 of the steering wheel 100 is arranged on the floor side of the vehicle 3 rather than the spoke 2 when the driver manually drives the vehicle 3, control the third drive unit 23 so that the connection portion 13 of the steering wheel 100 is arranged on the front side of the vehicle 3 rather than the spoke 2 when parking or during automatic driving, and control the third drive unit 23 so that the connection portion 13 of the steering wheel 100 is arranged on the ceiling side of the vehicle 3 rather than the spoke 2 when getting in and out.

[0177] According to this, the rotation position of the steering wheel 100 automatically changes according to the state of the vehicle 3 such as during driving, when parking, and when getting in and out, so that a special operation such as rotating the steering wheel 100 by the driver becomes unnecessary. For this reason, the convenience of the driver can be improved.

[0178] In addition, the vehicle steering devices 1b, 1d, and 1e of Technology 14 in this embodiment and the like are the vehicle steering devices 1b, 1d, and 1e described in Technology 13. In this case, the vehicle steering devices 1b, 1d, and 1e further include a table 50 stored in a storage space within a column cover 6 that covers the lower part of the steering column 4, and a fourth drive unit 24 that moves the table 50 from the steering column 4 to the rear side of the vehicle 3 and also moves it to the front side of the vehicle 3 and stores it in the storage space within the column cover 6. Then, the control units 30, 30b control the fourth drive unit 24 to move the table 50 from the steering column 4 to the rear side of the vehicle 3 when parking, and control the fourth drive unit 24 to move the table 50 to the front side of the vehicle 3 and store it in the storage space within the column cover 6 during driving or when getting on or off the vehicle.

[0179] According to this, when the vehicle 3 is parked, the table 50 is automatically pulled out in front of the driver's eyes. Therefore, the driver can perform work on the table 50 without performing any special operations. As a result, the convenience of the driver can be improved.

Also, the steering wheel 100 can be rotated manually. And the control units 30, 30c are electrically connected to the position sensor 60, and when it is determined based on the rotational position of the steering wheel 100 detected by the position sensor 60 that the connection portion 13 of the steering wheel 100 is disposed on the floor side of the vehicle 3 rather than the spoke 2, a drivable signal is output. When it is determined based on the rotational position of the steering wheel 100 detected by the position sensor 60 that the connection portion 13 of the steering wheel 100 is disposed on the front side of the vehicle 3 rather than the spoke 2, a parking signal is output. When it is determined based on the rotational position of the steering wheel 100 detected by the position sensor 60 that the connection portion 13 of the steering wheel 100 is disposed on the ceiling side of the vehicle 3 rather than the spoke 2, a door unlocking permission signal is output.

[0181] According to this, since respective signals are output to the ECU according to the position of the steering wheel 100, the ECU can perform appropriate control of the vehicle 3 according to these signals.

[0182] Also, the vehicle steering devices 1c, 1d, 1e of Technology 16 in the present embodiment and the like are the vehicle steering devices 1c, 1d, 1e described in Technology 15. In this case, the vehicle steering devices 1c, 1d, 1e further include a table 50 that is housed in a storage space within a column cover 6 that covers the lower part of the steering column 4 and can be manually pulled out, and a stopper 80 that is electrically connected to the control units 30, 30c and restricts the movement of the table 50. And the control units 30, 30c release the stopper 80 when the parking signal is output.

[0183] According to this, since the drawer of the table 50 is permitted only during parking and stopping, it is possible to suppress a decrease in safety during the running of the vehicle 3, and it is possible to achieve both the improvement in convenience that the table 50 can be used only during parking and stopping.

[0184] Further, the vehicle steering devices 1c, 1d, 1e of Technology 17 in the present embodiment etc. are the vehicle steering devices 1c, 1d, 1e described in Technology 16. In this case, when the control units 30, 30c output a drivable signal or a door unlocking permission signal, if the stopper 80 is in a released state, a warning for prompting to store the table 50 is output to the warning unit 70.

[0185] According to this, at the start of driving and at the start of boarding and alighting, when the table 50 is pulled out from the storage space in the column cover 6, a warning can be issued to the driver. Therefore, the driver can be prompted to store the table 50 in the storage space in the column cover 6. As a result, it is possible to suppress a decrease in safety during the running of the vehicle 3 and during the boarding and alighting of the driver with respect to the vehicle 3.

[0186] Further, the vehicle steering devices 1, 1a, 1b, 1c, 1d, 1e of Technology 18 in the present embodiment etc. are the vehicle steering devices 1, 1a, 1b, 1c, 1d, 1e described in any one of Technologies 7, 9, 14, 16. In this case, the table 50 further includes an input means 51.
