Description

Technical Field

[0001] This invention relates to a deformable knob, and more particularly to a deformable knob for use in a vehicle. Background Technology

[0002] In recent years, automobiles have increasingly utilized electronic systems to perform functions traditionally performed by mechanical systems. One area where mechanical systems have been significantly reduced in favor of electronic ones is the control system. More specifically, buttons, levers, and knobs once used to control systems such as radio broadcasting, HVAC, and transmissions have been replaced by touchscreen displays. Touchscreen displays follow a minimalist design style while maintaining the functionality of traditional control systems. Despite their usefulness, touchscreen displays provide only limited (if any) tactile feedback to the operator when making selections. The operator must typically shift their attention from the road to the display to make a selection and / or confirm that an appropriate selection has been made. In doing so, the operator increases the likelihood of an accident.

[0003] Therefore, while the current control system has achieved its intended purpose, a new deformable knob for vehicles is still needed to address these issues. Summary of the Invention

[0004] According to several aspects of this disclosure, a deformable knob for a transportation vehicle includes a shaft extending along an axis and a body mounted to and rotatable about the axis.

[0070] Figure 15 This is a flowchart illustrating another example of how a control system operates. Detailed Implementation

[0071] The following description is merely exemplary in nature and is not intended to limit this disclosure, its application, or its uses.

[0072] Reference Figure 12The control system is generally shown as 20. Control system 20 is configured for use with a vehicle 22. Control system 20 includes a controller 24, which includes at least one processor 26 and at least one non-transitory computer-readable medium 28 including instructions. The at least one non-transitory computer-readable medium 28 may include other data, such as control logic, software applications, instructions, computer code, data, lookup tables, etc. Computer-readable medium includes any type of media accessible by a computer, such as read-only memory (ROM), random access memory (RAM), hard disk drive, compact optical disc (CD), digital video optical disc (DVD), or any other type of memory. "Non-transitory" computer-readable medium does not include wired, wireless, optical, or other communication links that transmit transient electrical signals or other signals. Non-transitory computer-readable medium 28 may include media that can permanently store data and media that can store data and later rewrite it (e.g., rewritable optical discs or erasable memory devices). Computer code includes any type of program code, including source code, object code, and executable code. Processor 26 is configured to execute code or instructions.

[0073] The control system 20 also includes a deformable knob 30 configured to be operated by an operator between a first state and a second state, and to communicate electronically with the controller 24. Figure 1 As shown, the deformable knob 30 includes a body 32 with an outer peripheral wall 34 arranged to flex between a first configuration corresponding to a first state and a second configuration corresponding to a second state. In the example shown in the figures, the deformable knob 30 is disposed inside the vehicle 22. More specifically, the deformable knob 30 is mounted on a portion of the vehicle 22 within the reach of the operator, such as along the dashboard or center console of the vehicle 22. However, the deformable knob 30 can be used in any suitable location on the vehicle 22.

[0074] Reference Figure 12 The control system 20 also includes an output device 36, which is electronically communicated with the controller 24 and arranged to change between a first setting and a second setting. When the operator manipulates the deformable knob 30 from the first state to the second state, it sends an input signal to the controller 24 and actuates the outer peripheral wall 34 from the first configuration (see...). Figure 13A ) Flexing to the second configuration (see Figure 13B The controller 24 is configured to receive an input signal, and the processor 26 is programmed to compare the input signal with instructions in the at least one non-transitory computer-readable medium 28 and send an output signal to the output device 36 to remove the output device 36 from a first setting (see [link]). Figure 13A Change to the second setting (see Figure 13B ).

[0075] In one example, flexing the outer peripheral wall 34 between the first and second configurations is further defined as flexing the outer peripheral wall 34 uniformly from the first configuration and increasing the size of the body 32 to the second configuration. In another example, flexing the outer peripheral wall 34 between the first and second configurations is further defined as flexing the outer peripheral wall 34 from the first configuration and changing the shape of the body 32 to the second configuration. Manipulating the deformable knob 30 causes a change in the output device 36, and the configuration (e.g., size and / or shape) of the body 32 of the deformable knob 30 changes accordingly. Thus, the deformable knob 30 serves both as an input from the operator to control the output device 36 and as an output from the control system 20, providing the user with visual and tactile feedback for confirming the setting of the output device 36. More specifically, the operator can determine the setting of the output device 36 based on the configuration of the outer peripheral wall 34 of the deformable knob 30. Furthermore, the operator can determine the different configurations by touching the outer peripheral wall 34 (i.e., without visually inspecting the deformable knob 30), which prevents the operator from being distracted from the road while operating the vehicle 22. Therefore, the deformable knob 30 promotes safe driving practices.

[0076] like Figures 4A to 11B As shown, the deformable knob 30 includes a shaft 38 extending along axis A. A body 32 is mounted to the shaft 38 and is rotatable about axis A. The shaft 38 is mounted to a vehicle 22 (e.g., a dashboard and / or center console in the example above). The body 32 includes a panel 40 and an outer peripheral wall 34 coupled to the panel 40 and extending about axis A, as shown... Figures 1 to 2C As shown. Panel 40 and outer peripheral wall 34 define cavity 42, as... Figures 4A to 11B As shown. The outer peripheral wall 34 is arranged to flex relative to axis A. The deformable knob 30 also includes a plurality of engaging arms 44 disposed within the cavity 42 and movable toward and away from axis A, wherein the plurality of engaging arms 44 are configured to selectively engage and flex the outer peripheral wall 34 between a first configuration and a second configuration. The deformable knob 30 also includes an actuator 46 that engages with the plurality of engaging arms 44 and is arranged to move between a first position and a second position, wherein movement of the actuator 46 between the first position and the second position provides corresponding movement of the plurality of engaging arms 44 to flex the outer peripheral wall 34 between the first configuration and the second configuration, respectively.

[0077] like Figure 5 , Figure 6 , Figure 7 and Figure 9As shown, actuator 46 can extend along a first plane P1 orthogonal to axis A and define a first track 48 extending from axis A in a curved radial configuration. A plurality of engaging arms 44 include a first post 50 disposed in the first track 48. Rotation of actuator 46 causes the first post 50 to move within the first track 48, and correspondingly moves the plurality of engaging arms 44 between a first position and a second position. Deformable knob 30 may also include a guide plate 52 extending along a second plane P2 parallel to the first plane P1, wherein the plurality of engaging arms 44 are disposed between actuator 46 and guide plate 52. Guide plate 52 defines a second track 54 extending from axis A in a linear radial configuration. The plurality of engaging arms 44 include a second post 56 disposed in the second track 54. When actuator 46 moves the engaging arms 44 between the first and second positions, guide plate 52 remains stationary to guide the engaging arms 44 toward and away from axis A in linear motion. More specifically, the linear radial configuration of the second track 54 of the guide plate 52 guides movement toward and away from axis A, while the bending of the first track 48 of the actuator 46 converts the rotational motion of the actuator 46 into the linear motion of the arm 44.

[0078] The guide plate 52 can be fixed to the body 32, and when the actuator 46 moves the engaging arm 44 between a first position and a second position, the guide plate 52 maintains the rotational position of the engaging arm 44 relative to the body 32. Figure 5 In the example shown, the deformable knob 30 also includes a sleeve 58 fixed to the actuator 46 and rotatably coupled to the body 32, wherein the sleeve 58 extends along axis A, surrounds axis 38, and defines a sleeve track 60 having a helical configuration. The axis 38 includes a protrusion 62 extending outward from axis A and engaging the sleeve track 60, wherein linear movement of the body 32 along axis A causes the protrusion 62 to move along the sleeve track 60 and rotates the sleeve 58 to move the actuator 46 between a first position and a second position. Figure 5In the example shown, the operator pushes the body 32 downward toward the vehicle 22. The shaft 38 is fixed relative to the vehicle 22 and axis A. The protrusion 62 slides within the sleeve track 60. Because the sleeve track 60 has a helical configuration and the shaft 38 is fixed to the vehicle 22, the sleeve 58 begins to rotate about the shaft 38 as the body 32 moves downward. More specifically, the helical configuration causes the sleeve 58 to rotate. The sleeve 58 can rotate relative to the body 32, which prevents the body 32 from rotating with the sleeve 58 when the body 32 is pushed downward. The sleeve 58 is fixed to the actuator 46. Thus, the rotation of the sleeve 58 causes the actuator 46 to rotate, which moves the engagement arm 44 from a first position to a second position. The deformable knob 30 sends an input signal to the controller 24. The deformable knob 30 can remain in the second state. The deformable knob 30 can return to the first state by pulling the body 32 upward. The deformable knob 30 may also include a biasing member 64 that abuts against the body 32 and is configured to bias the body 32 toward the first state. Thus, the deformable knob 30 can automatically return to the first state after the operator presses the body 32.

[0079] exist Figure 6 In the example shown, actuator 46 is movable between a first position and a second position (independent of body 32), and electric motor 66 is coupled to actuator 46 and communicates electronically with controller 24. Processor 26 is also programmed to send configuration signals to electric motor 66 to move actuator 46 from the first position to the second position and to flex the outer peripheral wall 34 from the first configuration to the second configuration. More specifically, electric motor 66 is coupled to shaft 38 and configured to rotate shaft 38 about axis A. Shaft 38 is fixed to actuator 46. Rotation of shaft 38 by electric motor 66 causes actuator 46 to move between the first and second positions. Figure 6In the example shown, the operator pushes the body 32 downward toward the vehicle 22. The body 32 may include an anchor 68, and the vehicle 22 may define a receiver 70 to receive the anchor 68 and fix the body 32 in a second state in a manner that allows the body 32 to rotate about axis A. The shaft 38 is rotatable about axis A. The deformable knob 30 sends an input signal to the controller 24 and, in turn, receives a configuration signal. An electric motor 66 rotates the shaft 38 about axis A. The shaft 38 is fixed to an actuator 46. Thus, the rotation of the shaft 38 causes the actuator 46 to rotate, causing the engagement arm 44 to move from a first position to a second position. The deformable knob 30 can remain in the second state. The deformable knob 30 can return to the first state by pulling the body 32 upward. The deformable knob 30 may also include a biasing member 64 that abuts against the body 32 and is configured to bias the body 32 toward the first state. Thus, the deformable knob 30 can automatically return to the first state after the operator presses the body 32. When the deformable knob 30 returns to the first state, the engagement arm 44 can remain in the second position because the engagement arm 44 is connected to the electric motor 66 and its movement is independent of the movement of the body 32. However, when the deformable knob 30 returns to the first state, the engagement arm 44 can return to the first position.

[0080] The guide plate 52 can be fixed relative to axis A and maintains the rotational position of the engaging arm 44 when the body 32 rotates about axis A. Furthermore, the actuator 46 can be coupled to the body 32 and is movable between a first position and a second position, wherein the operator manipulating the deformable knob 30 from the first state to the second state is further defined as follows: the operator moves the body 32 from the first state to the second state, causing the actuator 46 to move accordingly from the first position to the second position to flex the outer peripheral wall 34 from the first configuration to the second configuration. Figure 7 In the example shown, actuator 46 is fixed to body 32 such that rotation of body 32 about axis A causes actuator 46 to move between a first position and a second position. More specifically, body 32 is fixed to shaft 38, and shaft 38 is rotatable relative to vehicle 22. Rotation of body 32 from the first state to the second state causes shaft 38 to rotate about axis A. Actuator 46 is fixed to shaft 38. Thus, rotation of shaft 38 causes actuator 46 to rotate, moving engagement arm 44 from the first position to the second position. Deformable knob 30 can be held in the second state. Rotation of body 32 back to the first state by the operator can return deformable knob 30 to the first state. Deformable knob 30 can also be rotatably biased back to the first state. Thus, deformable knob 30 can automatically return to the first state after the operator rotates body 32.

[0081] The movement of the plurality of connecting arms 44 causing the outer peripheral wall 34 to flex between the first and second configurations can also be defined as: moving the plurality of connecting arms 44 uniformly outward away from axis A to flex the outer peripheral wall 34 from the first configuration and increase the size of the body 32 to the second configuration (i.e., the size change described above). Alternatively, the movement of the plurality of connecting arms 44 causing the outer peripheral wall 34 to flex between the first and second configurations can also be defined as: moving a portion of the plurality of connecting arms 44 toward or away from axis A to flex the outer peripheral wall 34 from the first configuration and change the shape of the body 32 to the second configuration (i.e., the shape change described above).

[0082] exist Figures 4A to 10 In the example shown, the plurality of engagement arms 44 are configured as a plurality of plungers 72, each plunger 72 individually engaging a portion of the outer peripheral wall 34. Furthermore, each of the plurality of engagement arms 44 may individually include a first plunger 50 and a second plunger 56. Moreover, the actuator 46 may define a plurality of first tracks 48, and the guide plate 52 may define a plurality of second tracks 54. The first plunger 50 is individually disposed in the first track 48, and the second plunger 56 is individually disposed in the second track 54. Each of the plungers 72 may include a head 74. Each of the heads 74 may have a curved surface 76 configured to engage a corresponding portion of the outer peripheral wall 34, such as... Figure 4A and Figure 4B As shown. The curved surface 76 allows for the formation of shapes with curvature, not just polygons with angular corners. However, some or all of the plungers 72 may include a head 74 with a flat surface 78. Figure 8A and Figure 8B In the example shown, one portion of plunger 72 has a curved surface 76, and another portion of plunger 72 has a flat surface 78. The combination of the curved surface 76 and the flat surface 78 allows for a variety of different shapes, including polygonal shapes and shapes with curved sides.

[0083] like Figure 9 and Figure 10 As shown, actuator 46 may also be defined as a first actuator 46, and the plurality of plungers 72 may also be defined as a plurality of first plungers 72. The deformable knob 30 may also include a plurality of second plungers 80 and a second actuator 82 engaging with the plurality of second plungers 80, wherein the second actuator 82 is configured to move the plurality of second plungers 80 independently of the first actuator 46 and the plurality of first plungers 72, so that the shape of the body 32 changes between a first configuration and a second configuration. The plurality of first plungers 72 may be radially offset from the plurality of second plungers 80, such as... Figure 8A and Figure 8BAs shown, this allows plungers 72 and 80 to press against different portions of the outer peripheral wall 34 in different states due to the independent movement of the first actuator 46 and the second actuator 82. More specifically, the plurality of first plungers 72 and the plurality of second plungers 80 are arranged in an alternating pattern about axis A. When the body 32 rotates about axis A in a first rotational direction from a first state to a second state, the first actuator 46 causes the plurality of first plungers 72 to move outward from axis A. When the body 32 rotates in the first rotational direction, the plurality of second plungers 80 move inward toward axis A accordingly. When the body 32 rotates about axis A in a second rotational direction opposite to the first rotational direction from a second state to a first state, the second actuator 82 causes the plurality of second plungers 80 to move outward from axis A. When the body 32 rotates in the second rotational direction, the plurality of first plungers 72 move inward toward axis A accordingly. In this way, the plurality of first plungers 72 and the plurality of second plungers 80 help to flex the outer peripheral wall 34 into different shapes between the first and second positions.

[0084] exist Figure 4A , Figure 4B , Figure 8A and Figure 8B In the example shown, the outer peripheral wall 34 includes a plurality of knurled elements 84 arranged end-to-end and a plurality of hinges 86 individually disposed between the knurled elements 84. Flexing the outer peripheral wall 34 includes folding the knurled elements 84 relative to the hinges 86. Thus, the knurled elements 84 allow the outer peripheral wall 34 to fold into different shapes when different engaging arms 44 press against and move the outer peripheral wall 34. The outer peripheral wall 34 may include an elastomeric material, such that flexing the outer peripheral wall 34 includes bending the elastomeric material of the outer peripheral wall 34. Furthermore, flexing the outer peripheral wall 34 may include stretching the elastomeric material of the outer peripheral wall 34.

[0085] exist Figure 11A and Figure 11B In the example shown, multiple engaging arms 44 are substantially flat and overlap each other about axis A. The engaging arms 44 collectively fully engage the outer peripheral wall 34 about axis A. The engaging arms 44 rotate and move accordingly inward or outward while engaging the outer peripheral wall 34. The rotational movement of the engaging arms 44 causes the outer peripheral wall 34 to flex and change configuration between a first configuration and a second configuration. More specifically, the multiple engaging arms 44 are configured as a mechanical iris 88. Figure 11A and Figure 11B In the example shown, the mechanical iris 88 alters the dimensions of the outer peripheral wall 34. However, the engaging arm 44 can be positioned such that its rotational movement can facilitate a change in the shape of the outer peripheral wall 34.

[0086] As described above, the operator manipulating the deformable knob 30 from a first state to a second state can also be defined as the body 32 of the deformable knob 30 rotating about axis A from the first state to the second state, or the body 32 of the deformable knob 30 moving linearly along axis A from the first state to the second state. However, manipulating the deformable knob 30 can also be defined as sliding the deformable knob 30 along a surface, tilting the deformable knob 30, etc. Furthermore, manipulating the deformable knob 30 can include engaging the deformable knob 30 without moving the knob 30, for example, engaging a touch sensor disposed on the knob 30.

[0087] like Figure 13A and Figure 13B As shown, the output device 36 may include a display surface 90 arranged to display a first mark 92 and a second mark 94, wherein the display surface 90 displays the first mark 92 in a first setting and the second mark 94 in a second setting. The display surface 90 may be a screen capable of displaying images. The first mark 92 and the second mark 94 may include text, icons, etc., indicating the configuration of the output device 36 in the first setting and the second setting, respectively.

[0088] Reference Figure 12 The output device 36 may further include a driving control module 96 configured to change the dynamic characteristics of the vehicle 22 between a first driving mode and a second driving mode, wherein the first driving mode corresponds to a first setting and the second driving mode corresponds to a second setting. More specifically, the driving control module 96 may control suspension characteristics, such as the ratio of shock absorber damping of spring wheel vibration. The driving control module 96 may also control powertrain characteristics, such as the maximum power output of the electric motor at a given time (in an electric-powered vehicle) or the shift point of the transmission (in an internal combustion engine-powered vehicle). On the other hand, the output device 36 may also include a cabin comfort module 98 configured to change the environment within the vehicle 22 between a first comfort mode and a second comfort mode, wherein the first comfort mode corresponds to a first setting and the second comfort mode corresponds to a second setting. More specifically, the cabin comfort module 98 may control radio broadcasting, HVAC, and other systems that change the environment within the vehicle 22.

[0089] The terms "first" and "second" used above in connection with states, positions, configurations, settings, etc., are relative and do not indicate any importance or order. Furthermore, although the deformable knob 30 is described above as being manipulated between two states causing the outer peripheral wall 34 to change between two configurations and the output device 36 to change between two settings, this is for illustrative purposes only. It should be understood that the deformable knob 30 can be a control system 20, which can be configured for use in various states, configurations, settings, etc. As a non-limiting example, the driving control module 96 can change between five driving control modes, including travel mode, sport mode, track mode, off-road mode, and operator-configurable mode. Thus, the deformable knob 30 can be manipulated between five states, causing the outer peripheral wall 34 to change between five configurations. These configurations can each have different shapes, such as... Figures 2A to 3E As shown. Furthermore, the cabin comfort module 98 can switch between five comfort modes, including volume mode, tuning mode, temperature mode, fan speed mode, and fan position mode. Thus, the deformable knob 30 can be operated between five states, causing the outer peripheral wall 34 to change between five configurations. Each of these configurations can have a different shape (see again). Figures 2A to 3E ).

[0090] The operator's manipulation of the deformable knob 30 from a first state to a second state can also be defined as a primary manipulation of the deformable knob 30 from the first state to the second state. The operator can further perform an auxiliary manipulation of the deformable knob 30 from a first sub-state of the second state to a second sub-state of the second state, causing an auxiliary input signal to be sent from the deformable knob 30 to the controller 24. The processor 26 then compares the auxiliary input signal with instructions in the at least one non-transitory computer-readable medium 28 and sends an auxiliary output signal from the controller 24 to the output device 36, causing the output device 36 to change from a first sub-state of the second setting to a second sub-state of the second setting. Changing the output device 36 between settings and sub-sets is referred to as multi-function control. Changing the output device 36 only between settings is referred to as dedicated control.

[0091] The example above regarding the driving control module 96 is an example of dedicated control. The deformable knob 30 can be manipulated to change the driving control module 96 between five driving control modes. However, there is no sub-setting of driving control modes that can be changed by auxiliary manipulation of the deformable knob 30. In this example, the operator changes the driving control mode by rotating the body 32 of the deformable knob 30 between five states corresponding to the five driving control modes. However, the deformable knob 30 can be configured to change states by linearly moving the body 32 (i.e., pressing the body).

[0092] The example above regarding the cabin comfort module 98 is an example of multi-functional control. The deformable knob 30 can be primarily operated to change the cabin comfort module 98 between five comfort modes. The deformable knob 30 can also be secondarily operated to change the cabin comfort module 98 between at least two sub-settings of a selected comfort mode. Sub-settings may include volume level for a volume comfort mode, temperature level for a temperature comfort mode, fan speed for a fan speed comfort mode, etc. In this example, the operator changes the comfort mode by rotating the body 32 of the deformable knob 30 between five states corresponding to the five comfort modes. The operator can change the sub-setting of the selected comfort mode by linearly moving the body 32 (i.e., pressing the body). However, the reverse is also true (i.e., the knob 30 can move linearly to change between comfort modes and can rotate to change between sub-settings).

[0093] This article also discloses an operation method 200 for the control system 20, such as... Figure 14 and Figure 15 The method is illustrated in the figure. It includes: an operator performing an operation to move a deformable knob 30 from a first state to a second state (see box 202), sending an input signal from the deformable knob 30 to a controller 24 (see box 204), the controller 24 receiving the input signal (see box 206), and a processor 26 comparing the input signal with instructions in the at least one non-transitory computer-readable medium 28 (see box 208). The method also includes sending an output signal from the controller 24 to an output device 36 (see box 210), changing the output device 36 from a first setting to a second setting (see box 212), and flexing the outer peripheral wall 34 of the deformable knob 30 from a first configuration corresponding to the first state to a second configuration corresponding to the second state (see box 214).

[0094] In one example, the operator's manipulation of the deformable knob 30 from a first state to a second state (see box 202) is further defined as the operator rotating the body 32 of the deformable knob 30 about axis A from the first state to the second state. In another example, the operator's manipulation of the deformable knob 30 from a first state to a second state (see box 202) is further defined as the operator performing a linear movement of the body 32 of the deformable knob 30 along axis A from the first state to the second state.

[0095] The operator's manipulation of the deformable knob 30 from a first state to a second state (see box 202) can also be defined as the operator performing a primary manipulation of the deformable knob 30 from the first state to the second state. The method further includes: the operator performing an auxiliary manipulation of the deformable knob 30 from a first sub-state of the second state to a second sub-state of the second state (see box 216), sending an auxiliary input signal from the deformable knob 30 to the controller 24 (see box 218), and the controller 24 receiving the auxiliary input signal (see box 220). The method also includes the processor 26 comparing the auxiliary input signal with instructions in the at least one non-transitory computer-readable medium 28 (see box 222), sending an auxiliary output signal from the controller 24 to the output device 36 (see box 224), and changing the output device 36 from a first sub-state of the second setting to a second sub-state of the second setting (see box 226). Referring to box 202, the operator's main operation of moving the deformable knob 30 from the first state to the second state can also be defined as the operator moving the body 32 of the deformable knob 30 in a straight line along axis A from the first state to the second state. Referring to box 216, the operator's auxiliary operation of moving the deformable knob 30 from the first sub-state of the second state to the second sub-state of the second state can also be defined as the operator rotating the body 32 of the deformable knob 30 about axis A from the first sub-state of the second state to the second sub-state of the second state.

[0096] In one example, bending the outer peripheral wall 34 of the deformable knob 30 from a first configuration corresponding to a first state to a second configuration corresponding to a second state (see box 214) is further defined as bending the outer peripheral wall 34 uniformly from the first configuration corresponding to the first state and increasing the size of the body 32 to the second configuration corresponding to the second state. In another example, bending the outer peripheral wall 34 of the deformable knob 30 from a first configuration corresponding to a first state to a second configuration corresponding to a second state (see box 214) is further defined as bending the outer peripheral wall 34 from the first configuration corresponding to the first state and changing the shape of the body 32 to the second configuration corresponding to the second state.

[0097] like Figure 14 As shown, the method may further include moving the actuator 46 from a first position to a second position (see box 228) while the operator performs an operation to move the deformable knob 30 from the first state to the second state (see box 202) and flexes the outer peripheral wall 34 of the deformable knob 30 from a first configuration corresponding to the first state to a second configuration corresponding to the second state (see box 214). Alternatively (and referring to...) Figure 15The method may further include, after the processor 26 compares the input signal with the instructions in the at least one non-transitory computer-readable medium 28 (see box 208), sending a configuration signal to the electric motor 66 (see box 230) and moving the actuator 46 from a first position to a second position (see box 232), while flexing the outer peripheral wall 34 of the deformable knob 30 from a first configuration corresponding to the first state to a second configuration corresponding to the second state (see box 214).

[0098] As described above, the output device 36 may include a display surface 90 arranged to display a first mark 92 and a second mark 94. Thus, changing the output device 36 from a first setting to a second setting (see box 212) may include changing the first mark 92 displayed on the display screen in the first setting to the second mark 94 displayed on the display screen in the second setting.

[0099] Therefore, the deformable knob 30 offers several advantages. The deformable knob 30 functions as a physical controller, where changes in size and / or shape provide tactile feedback and clear confirmation for the operator's selections, helping the operator keep their attention on the road. Changes in size and / or shape further enhance the usability and performance of the control system 20, and provide personalization and comfort for the user. The deformable knob 30 further enhances the user experience during driving scenarios by providing a more intuitive interaction with the control system 20.

[0100] The description in this disclosure is merely exemplary in nature, and variations thereof that do not depart from the general meaning of this disclosure are intended to fall within its scope. Such variations should not be considered as departing from the spirit and scope of this disclosure.
