Description

Technical Field

[0001] The present disclosure relates to a manipulation system capable of controlling various functions in a vehicle, and more particularly, to a detachable manipulation system capable of corresponding to various manipulation environments using an electromagnet and a control method thereof. Background Art

[0002] The rotary steering system is a steering system that generally has a dial form and is manipulated to rotate about a central axis, and is used as a multi-purpose steering indicator because the steering system is intuitive and can integrate various functions.

[0003] In a vehicle, a rotary manipulation system is used to manipulate a control object having a continuous control amount such as volume and temperature, and is used as an integrated manipulation system such as a driver information system (DIS) or a central control point (CCP) to reduce the number of buttons.

[0004] However, in a general rotational manipulation system, it is impossible to change after design i) the manipulation steps per rotation (e.g., 360 degree rotation), ii) the torque required to rotate the angle corresponding to a single manipulation step, iii) the layout position, or iv) the manipulation type, such as endless, self-returning, or rotational.

[0005] At the same time, it is expected that in the future vehicle environment, with the advancement of autonomous driving technology, the boundary between the driver and the passenger will gradually disappear, and the seats will change freely, so that the position and posture of the passengers will also become free. In addition, due to enhanced personalization, the demand for customized user interfaces may further increase.

[0006] Therefore, there is a need for a manipulation system that can be detachably attached to a desired position regardless of a position or posture and corresponds to various user interface forms while solving the above-mentioned disadvantages of the general rotation manipulation system. Summary of the invention

[0007] Accordingly, the present disclosure is directed to a detachable manipulation system using an electromagnet and a control method thereof that substantially obviates one or more problems due to limitations and disadvantages of the related art.

[0008] An object of the present disclosure is to provide a detachable rotary steering system with improved convenience and a control method thereof.

[0009] Another object of the present disclosure is to provide a rotation manipulation system and a control method thereof that can correspond to various control environments.

[0010] The objects of the present disclosure designed to solve the problems are not limited to the above-mentioned objects, and other unmentioned objects should be clearly understood by those having ordinary skill in the art based on the following detailed description of the present disclosure.

[0011] To achieve these objects and other advantages and in accordance with the purposes of the present disclosure, as embodied and broadly described herein, a method of controlling a detachable rotary steering system may include determining whether a rotary steering unit having a plurality of magnets disposed therein has been attached based on current changes of a plurality of electromagnetic coils disposed at an attachment unit. The method may further include, after determining that the rotary steering unit has been attached, controlling whether to activate at least some of the plurality of electromagnetic coils based on at least one of the number of clicks per rotation corresponding to a function to be controlled or the type of steering system of the rotary steering unit.

[0012] In another aspect of the present disclosure, a steering device for a vehicle may include a plurality of electromagnetic coils arranged along an attachment unit and a controller. The controller may be configured to determine whether a rotary steering unit having a plurality of magnets arranged thereon has been attached based on a change in current of the plurality of electromagnetic coils. The controller may be further configured to control whether to activate at least some of the plurality of electromagnetic coils based on at least one of a number of clicks per rotation corresponding to a function to be controlled or a steering system type of the rotary steering unit when determining that the rotary steering unit has been attached.

[0025] Reference is now made in detail to embodiments of the present disclosure, examples of which are shown in the accompanying drawings. In order to enable those of ordinary skill in the art to fully understand the ideas of the present disclosure, the following embodiments are given by way of example. Therefore, the present disclosure is not limited by the following embodiments and may be implemented in various other forms. In order to clearly describe the present disclosure, parts that are not related to the description of the present disclosure are omitted from the accompanying drawings. Where possible, the same reference numerals are used throughout the specification to represent the same or equivalent parts.

[0026] Unless otherwise mentioned, the terms "comprising" or "including" used herein should be interpreted as not excluding other elements, but further including such other elements. In addition, throughout the specification, the same reference numerals represent the same or equivalent constituent elements. When a part, device, element, etc. of the present disclosure is described as having a purpose or performing an operation, function, etc., the part, device or element should be considered to be "configured to" meet the purpose or perform the operation or function in this article. In addition, the controller described herein may include a processor programmed to perform the operation, function, operation, etc.

[0027] In an embodiment of the present disclosure, it is proposed to sense and fix a rotation steering system using an electromagnet, and to change a control form of the rotation steering system based on an object to be controlled when controlling a vehicle function.

[0028] First, refer to Figure 1 The configuration of a rotation manipulation system that can be applied to an embodiment of the present disclosure is described. Figure 1 is a view showing an example of a configuration of a rotation manipulation system using an electromagnet according to an embodiment of the present disclosure.

[0029] refer to Figure 1 , the rotation manipulation system according to an embodiment of the present disclosure may include a manipulation unit 100 and an attachment unit 200 .

[0030] The manipulation unit 100 may include a body 110 and a plurality of magnets 120 arranged at the body 110. In addition, the attachment unit 200 may include an attachment surface 210 and a plurality of electromagnetic coils 220 arranged at the attachment surface 210. Although not shown, the attachment unit 200 may further include a controller configured to apply power to at least some of the plurality of electromagnetic coils 220 in order to perform control so that the electromagnetic coils 220 may act as N-pole or S-pole electromagnets. The controller may be further configured to sense current changes of at least some of the electromagnetic coils 220 according to changes in external magnetic force. Since the attachment unit 200 is constantly arranged on the vehicle side, the attachment unit 200 may be referred to as a "manipulation device for a vehicle".

[0031] Hereinafter, each component is described in detail.

[0032] First, the body 110 may have a cylindrical or disc-shaped appearance so as to be suitable for rotational manipulation. Of course, this is an illustrative example, and the present disclosure is not limited to the appearance of the body 110. However, in another embodiment, the face of the body 110 opposite to the attachment face 210 may be flat so as to be able to rotate smoothly.

[0033] The plurality of magnets 120 may be arranged in the body 110 or at a face of the body 110 opposite to the attachment face 210. However, the present disclosure is not limited thereto. However, in another embodiment, each of the plurality of magnets 120 is arranged parallel to the attachment face 210 or a surface of the body 110 opposite to the attachment face 210. In addition, the plurality of magnets 120 may include a plurality of peripheral magnets 121 and a central magnet 122. The plurality of peripheral magnets 121 may be arranged radially around the central magnet 122, or may be arranged to form concentric circles having the central magnet 122 as a center point.

[0034] Next, the attachment surface 210 of the attachment unit 200 can be arranged at various positions in the vehicle, taking into account the position and posture of the passengers in the vehicle and the functions to be controlled. For example, the attachment surface 210 can be attached to a seat, a console, a display, a steering wheel, etc. However, the present disclosure is not limited to this. In another embodiment, the attachment surface 210 is generally flat. However, except for the area of ​​the attachment surface 210 that overlaps with the operating unit 100 when the operating unit 100 is attached to the attachment surface 210, the attachment surface 210 may be curved or uneven.

[0035] A plurality of electromagnetic coils 220 may be arranged on the attachment surface 210 or at the rear of the exposed portion of the attachment surface 210. However, the present disclosure is not limited thereto. However, in another embodiment, each of the plurality of electromagnetic coils 220 is arranged parallel to the attachment surface 210. In addition, the electromagnetic coil 220 may include a plurality of peripheral electromagnetic coils 221 and a central electromagnetic coil 222. The plurality of peripheral electromagnetic coils 221 may be arranged radially around the central electromagnetic coil 222, or may be arranged to form concentric circles with the central electromagnetic coil 222 as the center point. In another embodiment, the distance between the central electromagnetic coil 222 and each peripheral electromagnetic coil 221 is equal to the distance between the central magnet 122 and each peripheral magnet 121. In addition, in another embodiment, the angle between each peripheral electromagnetic coil 221 has a multiple relationship with the angle between each peripheral magnet 121. For example, the angle between each peripheral electromagnetic coil 221 may be equal to the angle between each peripheral magnet 121. Therefore, the magnet 120 and the electromagnetic coil 220 have a one-to-one correspondence, so that when viewed from the front after attachment, the magnet 120 completely overlaps the electromagnetic coil 220. In another example, the angle between each peripheral magnet 121 can be 60 degrees, and the angle between each peripheral electromagnetic coil 221 can be 30 degrees, thereby having a 1:2 correspondence.

[0036] It is sufficient for a controller (not shown) of the attachment unit 200 to be electrically connected to each of the plurality of electromagnetic coils 220. The controller does not need to be arranged adjacent to the attachment surface 210 or the electromagnetic coils 220.

[0037] In some embodiments, the center electromagnetic coil 222 may be replaced with a permanent magnet.

[0038] Figure 2 1 is a view showing an example of a fixing form of a rotation manipulation system according to an embodiment of the present disclosure. Figure 2In the following embodiments, it is assumed that a single central magnet 122 and a single central electromagnetic coil 222 are provided. Twelve peripheral magnets 121 and twelve peripheral electromagnetic coils 221 are provided so as to have an angle of 30 degrees between the corresponding peripheral magnets 121 and between the corresponding peripheral electromagnetic coils 221. When the manipulation unit 100 is attached to the attachment surface 210 of the attachment unit 200, the magnet 120 overlaps with the electromagnetic coil 220 so as to have a one-to-one correspondence. In addition, for convenience, the "electromagnetic coil" may also be referred to as an "electromagnet".

[0039] exist Figure 2 In the figure, for a clear understanding, only the electromagnetic coil 220 and the magnet 120 are shown. Figure 2 , an attractive force is constantly applied between the central magnet 122 and the central electromagnet 222. Therefore, the central magnet 122 and the central electromagnet 222 may be used as a rotation axis for rotation manipulation of the manipulation unit 100.

[0040] In addition, the attractive force between the central magnet 122 and the central electromagnet 222 may be greater than or equal to the attractive force between the peripheral magnet 121 and the peripheral electromagnet 221 .

[0041] Figures 3(a) to 3(e) is a view showing an example of a magnetic force control form during rotation of a rotation manipulation system according to an embodiment of the present disclosure.

[0042] refer to Figures 3(a) to 3(e) , the curve is shown in Figure 3(e), while Figures 3(a) to 3(d) Specifically, the horizontal axis of the curve graph of FIG3(e) corresponds to Figure 3(a) to Figure 3(d) The vertical axis in FIG3(e) represents the intensity of the magnetic force generated by the peripheral electromagnet 221.

[0043] First, in a state where the user does not manipulate the manipulation unit 100, as shown in FIG3(a), the controller of the attachment unit 200 applies a current having a first magnitude to the peripheral electromagnet 221 to fix the manipulation unit 100 so that it does not move due to the vibration of the vehicle. In the case where the user attempts to perform a rotation manipulation, as shown in FIG3(b), the controller can determine whether the user intends to rotate the manipulation unit 100 based on the current change of each electromagnet generated by the reaction force. When the user's body contacts the body 110 of the manipulation unit 100 and the user attempts to rotate the manipulation unit 100, the reaction force is caused by the change in magnetic force. As a result, as shown in FIG3(c), when the rotation of the manipulation unit 100 caused by the current change is sensed, the controller can apply a current having a second magnitude less than the first magnitude to the peripheral electromagnet 221 to reduce the magnetic force and thus help smooth rotation. In addition, when rotating a predetermined angle (e.g., an angle corresponding to a click based on a current object to be controlled or an angle between corresponding peripheral electromagnets) or more, as shown in FIG. 3( d), the controller increases the magnetic force so that the manipulation unit 100 is fixed to the next magnet-electromagnet alignment position. At this time, the controller may determine the rotation direction and rotation angle of the manipulation unit 100 based on the current change of the peripheral electromagnet 221. The controller may also control the current function to be controlled based on the determined rotation direction and rotation angle.

[0044] At the same time, the controller of the attachment unit 200 can change the type of the manipulation system using the principle that the strength and direction of the magnetic force generated by the electromagnet can be changed according to the application of current. In other words, when the manipulation unit 100 is rotated by a predetermined angle or more, the manipulation unit 100 moves differently according to the type of power applied to the peripheral electromagnet 221. This is referred to as the attachment. Figures 4(a) to 4(c) Give a description.

[0045] Figures 4(a) to 4(c) 2 is a view showing an example of a magnetic force control form of a rotation steering system according to an embodiment of the present disclosure according to a steering system type.

[0046] First, each time the predetermined angle is rotated, according to Figures 3(a) to 3(e) The controller controlling the electromagnet shown in the figure, or by increasing the strength of the next peripheral electromagnet in the same direction as the rotation direction, the manipulation unit 100 stops at the next click in the rotation direction (i.e., at a position where the peripheral magnet 121 and the peripheral electromagnet 221 overlap to form a pair). In this embodiment, the manipulation unit 100 can be operated as an endless manipulation system capable of performing endless rotation regardless of the rotation direction, as shown in FIG. 4( a).

[0047] In another embodiment, the controller can increase the strength of the electromagnet in the direction opposite to the rotation direction, i.e., the strength of the electromagnet at the initial starting position, as shown in FIG4(b), so that the manipulation unit 100 can return to the initial position before the rotation manipulation. In this embodiment, the manipulation unit 100 can be operated as a self-returning manipulation system, as shown in FIG4(c).

[0048] Next, refer to Figure 5 Describes a click-variable control.

[0049] Figure 5 : is a view showing an example of a magnetic force control form of a rotation manipulation system according to an embodiment of the present disclosure according to the number of clicks.

[0050] First, in the case where all twelve peripheral electromagnets 221 are activated, as on the left side, the manipulation unit 100 rotates once (i.e., the rotation angle θ1 of each click is 30 degrees) and can click twelve times. On the other hand, in the case where only half of the twelve peripheral electromagnets are alternately activated as on the right side, the manipulation unit 100 rotates once and can click six times (i.e., the rotation angle θ2 of each click is 60 degrees). Of course, in any case, the manipulation torque per click can be changed according to the current intensity applied by the controller to the activated peripheral electromagnets.

[0051] Figures 6(a) to 6(b) is a view showing an example of a magnetic force control form of a rotation manipulation system according to an embodiment of the present disclosure, which depends on the configuration of an object to be controlled.

[0052] exist Figures 6(a) to 6(b) In the description, a case is assumed in which each menu constituting a function to be controlled is output through the display 300 in the vehicle, including a plurality of menus, and one menu is moved each time it is clicked.

[0053] First, in the case where four separate menus are provided, as shown in FIG. 6( a ), the peripheral electromagnet 221 may be selectively activated so that the manipulation unit 100 rotates once four times.

[0054] In another embodiment, where eight separate menus are provided, as shown in FIG. 6( b ), the peripheral electromagnet 221 may be selectively activated so that the manipulation unit 100 rotates once eight times.

[0055] Of course, in another embodiment, the peripheral magnet 121 and the peripheral electromagnet 221 are set with numbers corresponding to integer multiples of the number of clicks based on the menu so as to equally divide the rotation angle of each click.

[0056] As a result, the user can perform more intuitive manipulation, and when a manipulation in the direction toward the last menu is sensed, the controller can increase the strength of the magnetic force of the peripheral electromagnet so that the rotation manipulation is no longer performed on the last menu provided. Therefore, tactile feedback about the total number of menus is provided. Therefore, blind control can be further easily performed during driving.

[0057] Figure 7 is a view illustrating an example of a configuration of a user interface for adjusting a rotation strength of a rotation manipulation system according to an embodiment of the present disclosure.

[0058] refer to Figure 7 , a personalized setting menu can be provided through the display 300 in the vehicle so that the strength of the magnetic force can be adjusted because people have different grip and wrist strength. For example, a personalized setting menu can be provided through a user setting mode (USM) of a head unit or an audio / video / navigation (AVN) system. As a result, a magnetic force suitable for an individual situation can be provided. Therefore, usability can be improved.

[0059] In another embodiment, the personalized setting menu is selected / manipulated only when a shift to P is performed in the transmission during a stop to prevent accidents during driving, and logic is set so that the shift is not performed in the P state of the transmission until the manipulation unit 100 is attached to the attachment surface 210 and the setting is completed. In the case of a shift after attachment, in order to prevent disengagement at the time of starting, the magnetic force may be automatically temporarily increased.

[0060] Figures 8(a) to 8(d) is a view showing an example of a magnetic force control form of a rotation manipulation system for forward alignment according to an embodiment of the present disclosure.

[0061] In the case where the manipulation unit is not a circle or a regular polygon, directivity is required. For example, in the case where the protrusion 130 is provided at a portion of the edge of the manipulation unit 100, such as Figures 8(a) to 8(d) As shown, or in the case where the display is set on the manipulation unit 100 so that directionality is required, an automatic alignment function can be provided. Figures 8(a) to 8(d) In the embodiment of the present invention, the polarity of the peripheral magnet 121 can be alternately changed in one rotation direction.

[0062] Referring to FIG8(a), it is assumed that the even peripheral magnets 121 have N polarity, the odd peripheral magnets 121 have S polarity, the protrusions 130 are arranged in the direction in which the first magnet is arranged, and the form in which the protrusions face upward is the forward direction expected during manufacturing. In addition, control is performed so that the polarity of the peripheral electromagnets 221 changes alternately. When the user attaches the manipulation unit 100 to the attachment surface 210 so that the protrusions 130 point to 2 o'clock in this state, as shown in FIG8(b), the controller can determine the direction in which the manipulation unit 100 is attached, and can start to perform forward alignment control.

[0063] Specifically, as shown in FIG8( c ), for the positive alignment of the manipulation unit 100, a double-click rotation must be performed in the counterclockwise direction. Therefore, the controller can control the peripheral electromagnet 221 so that a repulsive force is generated in the clockwise direction between the peripheral magnet 121 and the peripheral electromagnet 221. An attractive force is generated in the counterclockwise direction between the peripheral magnet 121 and the peripheral electromagnet 221. The peripheral electromagnet 221 can be controlled so that the polarity of the peripheral electromagnet 221 is alternately changed at each single-click rotation, so that the attractive force and the repulsive force sequentially applied to the peripheral magnet cause the manipulation unit 100 to rotate in the counterclockwise direction.

[0064] Subsequently, as shown in FIG. 8( d ), in a case where the manipulation unit 100 is aligned in the forward direction, the controller may control the peripheral electromagnets so that an attractive force is applied between the overlapping peripheral magnets 121 and 221 .

[0065] In the case where the user attaches the manipulation unit 100 to a desired position, the manipulation unit 100 can be aligned in the forward direction. Therefore, usability can be improved.

[0066] However, in order to provide such a function, the controller needs to determine the positive direction of the manipulation unit 100. To this end, the strength of the magnetic force of a specific one of the peripheral magnets 121 (e.g., the first peripheral magnet) may be different from the strength of the magnetic force of the other peripheral magnets 121. In another embodiment, the polarity arrangement of at least some of the peripheral magnets 121 may be different from the polarity arrangement of the other peripheral magnets 121. For example, the twelfth peripheral magnet, the first peripheral magnet, and the second peripheral magnet may have the same polarity, while the other third peripheral magnets to the eleventh magnet may have alternating polarities. Of course, this arrangement is exemplary, and the arrangement is not limited, as long as the controller can determine the direction in which the manipulation unit 100 is arranged.

[0067] Figures 9(a) to 9(c) is a view showing an attachment area according to an embodiment of the present disclosure.

[0068] 9(a), the attachment area where the attachment surface 210 of the attachment unit 200 is located may be a point 910 or 920 on the steering wheel. In another embodiment, as shown in FIG9(b), the connection area 930 may be arranged in the middle of the center panel.

[0069] Of course, in some embodiments, multiple attachment areas 931, 932, 933, and 934 may be provided in the middle of the center panel, as shown in FIG9(c). In this embodiment, multiple manipulation units 100 may be attached simultaneously to form part of the manipulation system, and different functions to be controlled may be provided according to the attachment areas. For example, in the case where the manipulation unit 100 is mounted on the leftmost mounting area 931, the air conditioner may be directly controlled by the manipulation unit 100 mounted on the mounting area 931. In the case where the manipulation unit 100 is attached to the rightmost attachment area 934, the volume of the multimedia output may be directly controlled. Of course, such a functional allocation is illustrative, and it is obvious to a person of ordinary skill in the art that the present disclosure is not limited thereto, and various changes are possible.

[0070] The process of controlling the rotation control system according to the above-mentioned embodiment of the present disclosure can be summarized as follows: Fig.10 shown.

[0071] Fig.10 is a flowchart illustrating an example of a process of controlling a rotation handling system according to an embodiment of the present disclosure.

[0072] refer to Fig.10 , the controller of the attachment unit 200 may monitor the current change of the electromagnet 220 to monitor the attachment or non-attachment of the manipulation unit 100 (S1001).

[0073] During monitoring, the controller may sense attachment or non-attachment of the manipulation unit 100 based on a change in current caused by at least a portion of the user's body contacting the manipulation unit 100 or the manipulation unit 100 approaching the magnet 120 ( S1002 ).

[0074] In the case where the attachment of the manipulation unit 100 is sensed (Yes in S1002), the controller may determine whether the manipulation unit 100 is to be aligned in the forward direction (S1003). Whether the manipulation unit 100 is to be aligned may be determined by determining whether a change in the magnetic force of a specific peripheral electromagnet is different from that of other peripheral electromagnets or whether a polarity pattern of some electromagnets is different from that of other electromagnets.

[0075] In case the manipulation unit 100 is aligned, forward alignment control may be performed (S1004).

[0076] Of course, in some embodiments, step S1003 and step S1004 may be omitted.

[0077] When the manipulation unit 100 is attached or the forward alignment of the manipulation unit 100 is completed, the controller confirms the function to be controlled, that is, the object to be controlled, by the rotation manipulation of the manipulation unit 100 (S1005). When determining the object to be controlled, the controller may consider at least one of the position of the attachment surface 210 to which the manipulation unit 100 is attached, the currently enabled function, or the current driving condition. The position of the attachment surface 210 is the same as described with reference to FIG. 9 (c), and the function displayed on the display of the AVN system may be considered as the currently enabled function. In addition, in the case of a driving condition, functions that cause the driver's attention to be distracted during driving may be excluded from the objects to be controlled. In addition, the confirmation of the object to be controlled may also include the confirmation of the construction of the menu of the object to be controlled and the confirmation of the corresponding manipulation system type.

[0078] Therefore, the controller can control the activation state of the electromagnet to correspond to the object to be controlled (S1006). For example, the controller can determine the type of manipulation system, such as an endless type or a self-returning type, as previously described with reference to Figures 4(a) to 4(c) As described above, this depends on the object to be controlled. In another example, the controller may determine the number of clicks or whether to apply the rotation prevention control corresponding to the last menu, as previously described with reference to Figure 5 and Figures 6(a) to 6(b) As described, this depends on the construction of the menu of the object to be controlled.

[0079] Subsequently, when the rotation of the manipulation unit 100 is sensed (S1007), the controller may reduce the magnetic force of the peripheral electromagnet during the rotation, as previously described with reference to FIG. Figures 3(a) to 3(e) As described, alternatively, the controller may control the change of the magnetic force based on the type of manipulation system whenever a rotation of a predetermined angle is performed, as previously described with reference to Figures 4(a) to 4(c) As described, therefore, the magnetic force can be controlled during rotation (S1008).

[0080] When the rotation completion of the manipulation unit 100 is sensed (S1009), the controller may fix the manipulation unit 100 to the position where the rotation is completed or return the manipulation unit 100 to the initial rotation position based on the manipulation system type corresponding to the object to be controlled. Therefore, the magnetic force may be controlled after the rotation, and the function to be controlled may be controlled in response to the sensed rotation direction and angle (S1010).

[0081] The rotation manipulation system using an electromagnet and the control method thereof according to the embodiments of the present disclosure described above may have the following effects.

[0082] First, the design freedom of the operating system in the vehicle can be increased, and intuitive usability can be improved due to the reduction of switches. In another example, the center panel / floor console switches can be integrated by integrating functions.

[0083] In addition, since the manipulation system is mounted / detached using magnetic force, usability is improved. In other words, since the magnetic force of a permanent magnet or an electromagnet is used instead of a mechanical structure for fixing the manipulation unit to the attachment surface, attachment is achieved simply by moving the manipulation unit close to the attachment surface. Thus, convenience is improved.

[0084] Furthermore, during driving, due to the tactile manipulation feeling through the change of magnetic force, there is no need to confirm the degree of manipulation with the naked eye, which is accompanied by neglect of attention.

[0085] The present disclosure described above may be implemented as a computer-readable program stored in a computer-readable recording medium. The computer-readable medium may be any type of recording device that stores data in a computer-readable manner.
