Referring to FIG. 1 to FIG. 4, a knob 10 may include a body 110 having an aperture 111 in a center thereof, an exterior touch panel 121 disposed at an exterior surface of the body 110, and an interior touch panel 122 disposed at an interior surface of the body 110 which is a side surface of the aperture 111. In addition, the knob 10 may further include an open and shut structure 130 configured to open and close the aperture 111.
The body 110 may have a cylindrical shaped and may include the aperture 111 in the center thereof. Additionally, the body 110 may have the exterior touch panel 121 disposed on the exterior surface thereof and the interior touch panel 122 disposed on the interior surface thereof, to allow the body 110 to receive touch inputs on the exterior surface thereof and the interior surface thereof. For example, the exterior touch panel 121 may be disposed on the exterior surface of the body 110, and may be configured to detect a touch input on the exterior surface of the body 110. Additionally, the interior touch panel 122 may be disposed at the interior surface of the body 110 which is a side surface of the aperture 111, and may be configured to detect a touch input on the interior surface of the body 110.
As shown in FIG. 1, an exterior circumference of the body 110 where the exterior touch panel 121 is disposed and an interior circumference of the body 110 where the interior touch panel 122 is disposed may have a curved shape. Therefore, the exterior circumference and the interior circumference of the body 110 may include a touch sensor having a flexible metal mesh structure. The aperture 111 may be formed with the body 110, and may be selectively opened and closed (e.g. shut). When opening the aperture 111, foreign particles may be inserted into (e.g., may flow into) the aperture 111 causing a potential malfunction of the interior touch panel 122. Therefore, as shown in FIG. 3, an open and shut structure 130 configured to open and close the aperture 111 may be disposed at the aperture 111.
The open and shut structure 130 may be configured to automatically open and close the aperture 111. Accordingly, the interior touch panel 122 may be exposed to the exterior or covered by the open and shut structure 130. In particular, the knob 10 may further include a driving motor (not shown) configured to open and close the open and shut structure 130 based on an input control signal. The open and shut structure 130 may be automatically opened and shut based on a touch input on the exterior touch panel 121, a vehicle speed, and a currently selected menu.

The plurality of shutter blades 131 may be rotatably coupled to the aperture 111 of the body 110, and may be disposed to be engaged with each other. The plurality of shutter blades 131 may rotate by interlocking with a rotation operation of the rotational orbit member 133 to cause the plurality of shutter blades 131 to open and close the aperture 111 based on a rotating direction.
In the FIG. 4, the shutter blade 131 is shown as a triangle shape, but this is merely an exemplary embodiment of the present invention, and the shutter blade 131 may be modified in other shapes and forms. The plurality of fixing members 132 may be configured to rotatably fix each shutter blade 131 to the body 110, and operate as rotation axes of each shutter blade 131. In other words, the shutter blades 131 may be configured to rotate around the fixing member 132s. The rotational orbit member 133 may be rotated by a driving torque transmitted from the driving motor. The rotational orbit member 133 may have a ring shape, and may be configured to rotate on the aperture 111 in a clockwise or anticlockwise direction. Each shutter blade 131 may be sequentially coupled to the ring shaped rotational orbit member 133 along a circumference of the rotational orbit member 133. Accordingly, the plurality of shutter blades 131 may be configured to rotate on the fixing member 132 by interlocking with a rotation operation of the rotational orbit member 133.
According to an exemplary embodiment of the present invention as described above, the knob 10 may include touch panels at an interior surface as well as an exterior surface, and may correspond to distinguishable functions to the exterior touch panel 121 and the interior touch panel 122. Thus, the knob 10 may be configured to receive various driver inputs using a simplified operation. The knob 10 may be included in a knob controller for a vehicle such as a driver information system (DIS) in a center fascia and used as manipulation device.
Hereinafter, a knob controller for a vehicle according to an exemplary embodiment of the present invention will be described in detail with reference to FIG. 5 and FIG. 6. FIG. 5 is an exemplary schematic block diagram showing a knob controller for a vehicle according to an exemplary embodiment of the present invention. In addition, FIG. 6 is an exemplary drawing illustrating a method of receiving a touch input through a display in a knob controller for a vehicle according to an exemplary embodiment of the present invention.
Referring to FIG. 5, a knob controller for a vehicle according to an exemplary embodiment of the present invention may include a knob 10, an open and shut driver 20, a touch gesture detector 30, a display 40, a memory 50, and a controller 60. The knob 10 may include an exterior touch panel 121, an interior touch panel 122, and an open and shut structure 130. The controller 60 may be configured to operate the open and shut driver 20, the touch gesture detector 30, the display 40, and the memory 50. In addition, the touch gesture detector 30 may be a sensor.
The exterior touch panel 121 may be coupled to an exterior surface of the body 110, and may be configured to receive a touch input on the exterior surface of the body 110. For example, the exterior touch panel 121 may be configured to receive a touch gesture of dragging on the exterior surface of the body 110 (e.g., a pressure is maintained while be moved along the panel) and a touch gesture of tapping on the exterior surface of the body 110. The interior touch panel 122 may be coupled to an interior surface of the body 110, and may be configured to receive a touch input on the interior surface of the body 110. For example, the interior touch panel 122 may be configured to receive a touch gesture of dragging on the interior surface of the body 110 and a touch gesture of tapping on the interior surface of the body 110. The open and shut structure 130 may be configured to expose the interior touch panel 122 or block the interior touch panel 122 by selectively opening and closing (e.g., shutting) the aperture 111 of the body 110.
The knob 10 may be mounted on the display 40 of the knob controller for a vehicle as shown in FIG. 6. The open and shut driver 20 may include a driving motor (not shown) configured to rotate the open and shut structure 130 to cause the open and shut driver 20 to rotate the open and shut structure 130 in a clockwise or anticlockwise direction based on a control signal from the controller 60. Meanwhile, the open and shut driver 20 and the knob 10 may be provided separately in the exemplary embodiment of the present invention as shown in FIG. 5, but they are not limited thereto. In another exemplary embodiment of the present invention, the open and shut driver 20 may be formed integrally at the knob 10. The open and shut structure 130 may be configured to prevent malfunction of the interior touch panel 122 caused by inflow of foreign particles by closing the aperture 111.
The touch gesture detector 30 may include a light emitting portion 310 and an imaging device 320 (e.g., camera, video camera, or the like). As shown in FIG. 6, the light emitting portion 310 may be configured to radiate light to a rear surface of the display 40, and the imaging device 320 may be configured to acquire an image of light radiated from the light emitting portion 310 and reflected from the rear surface of the display 40. The image photographed or captured by the imaging device 320 may be transmitted to the controller 60, and the controller 60 may be configured to detect a touch gesture (e.g., applied pressure) regarding the display 40 by analyzing the image.
In an exemplary embodiment of the present invention, FIG. 6 illustrates that the light emitting portion 310 and the imaging device 320 are disposed at a rear lower surface of the display 40, but the present invention is not limited thereto. According to an another exemplary embodiment of the present invention, the light emitting portion 310 and the imaging device 320 may be disposed at a lower end of the knob 10 or disposed at a bottom of the aperture 111. In particular, the light emitting portion 310 may be configured to radiate light to the lower end of the knob 10 or to an opening of the aperture 111, and the imaging device 320 may be configured to capture an image of reflective light.
Further, the display 40 may be configured to output (e.g., display) information processed by the knob controller on a screen. The memory 50 may be configured to store a program for operation of the controller 60 and various data processed by the controller 60. Additionally, the memory 50 may be configured to store data regarding a user interface (UI) output on the display 40. For example, the memory 50 may be configured to store graphics data and a menu structure to display the UI. The memory 50 may be configured to build or generate a database and store functions that correspond to touch inputs input by the knob 10 by forming the database.
Herein, the memory 50 may correspond to a distinguishable function or menu between the touch input through the exterior touch panel 121 and the touch input through the interior touch panel 122. For example, the touch input of the exterior touch panel 121 may correspond to a higher menu such as an audio device, an air conditioning device, and a navigation device, and the touch input of the interior touch panel 122 may correspond to a lower menu such as a volume control and a temperature control. In addition, the memory 50 may be configured to build a database and store functions that correspond to touch gestures detected by the touch gesture detector 30 in the database. The controller 60 may be configured to operate the knob controller for the vehicle.
The controller 60 may be configured to receive the touch input through the knob 10, and perform a corresponding function. When the controller 60 receives the touch input through the knob 10, the controller 60 may be configured to determine through which touch panel the touch is input through between the exterior touch panel 121 and the interior touch panel 122, and perform a function that corresponds to the touch panel. The controller 60 may also be configured to select a specific higher menu based on the touch input when the touch input of the exterior touch panel 121 is input through the knob 10. In other words, the controller 60 may be configured to select the specific higher menu by adjusting a rotation direction and a rotation amount when the touch input of the exterior touch panel 121 is input through the knob 10.
Furthermore, the controller 60 may be configured to adjust a moving speed between the menu based on a touch speed even when the rotation amount of the touch input is the same (e.g., the amount of pressure applied is about that same). In addition, the controller 60 may be configured to select a specific lower menu based on the touch input when the touch input of the interior touch panel 122 is input through the knob 10. In other words, the controller 60 may be configured to adjust moving between lower menus (e.g., sub menus) included in a currently selected higher menu (e.g., main menus) based on a rotation direction and a rotation amount when the touch input of the interior touch panel 122 is input through the knob 10. For example, when the currently selected higher menu is music, the controller 60 may be configured to select a lower menu or a sub menu of the music function such as a search and a volume control based on the touch input of the interior touch panel 122.
In addition, the controller 60 may be configured to perform a function that corresponds to the lower menu based on a touch position when a tapping touch input is input through the interior touch panel 122. The controller 60 may further be configured to operate the open and shut driver 20 to expose the interior touch panel 122 or block the interior touch panel 122 of the knob 10. When the touch input on the exterior touch panel 121 of the knob 10 is input, the controller 60 may be configured to determine an intention to operate a menu and operate the open and shut driver 20 to expose the interior touch panel 122. In particular, when the touch input on the exterior touch panel 121 of the knob 10 is not input more than a predetermined number of times (e.g., is input less than a predetermined number of times), the controller 60 may be configured to operate the open and shut driver 20 to block the interior touch panel 122. For example, the controller 60 may be configured to operate the open and shut driver 20 to expose the interior touch panel 122 when a vehicle speed is greater than or equal to a predetermined speed.
Additionally, the controller 60 may be configured to operate the open and shut driver 20 to open or close the aperture 111 of the knob 10 based on a currently displayed menu. In particular, when the currently displayed menu is determined to require a particular lower menu, the controller 60 may be configured to operate the open and shut driver 20 to open the aperture 111 of the knob 10 and expose the interior touch panel 122. When the currently displayed menu is determined to not require a particular lower menu, the controller 60 may be configured to operate the open and shut driver 20 to close the aperture 111 of the knob 10 and block the interior touch panel 122. The controller 60 may further be configured to detect a touch gesture at the display 40 using the touch gesture detector 30, and perform a function that corresponds to the touch gesture. In particular, the controller 60 may be configured to detect the touch gesture by analyzing the image photographed by the imaging device 320.
As described above, according to an exemplary embodiment of the present invention, touch panels that have distinguishable functions may be applied to an exterior surface and an interior surface of the knob, to allow a driver to operate the knob to perform a corresponding menu function. Therefore, the driver may execute a menu with a touch, thereby minimizing driver distraction.
