Here, N denotes the number of turns of the core coil wound around the vertical extension portion, I denotes the applied current applied to the core coil, and Bg denotes the magnetic flux density of the void.

Where μ0 represents the magnetic permeability of the vacuum and Fd represents the magnetic attraction between the rotary core and the rotary disk. Thus, Fd can be expressed by the applied current I. FIG. 13 is a schematic cross sectional view of a haptic actuator in a state before a current I is applied to a core coil, and FIG. 14 is a schematic cross sectional view of a haptic actuator in a state after a current I is applied to a core coil.

As shown in FIG. 13, although the contact between the end of the rotary core 340 and the intersection area of the rotary disk 355 is made due to the weight of the rotary core, the magnetic attraction force due to the current I does not work between them. There is a significant play d1 between the core 340 and the fixed plate 320. On the other hand, when the current I is applied to the core coil as shown in FIG. 14, a significant force is applied between the end of the rotary core 340 and the intersection region of the rotary disk 355 by the magnetic attraction force, thereby causing the rotary core 340 to be rotated. And elastic deformation is applied to the rotary elastic member 330 disposed between the fixed plate 320 and the fixed plate 320 to reduce the clearance d2 between the fixed plate 320 and the rotary core 340. Therefore, the following relationship is formed in the clearances d1 and d2 between the fixed plate 320 and the rotary core 340 before and after the current I is applied to the core coil.

Therefore, when a current I is applied to the core coil and an action force P for generating rotational torque is applied to the rotary knob by the user, F2 and T are expressed as follows.

The current I is applied to the core coil according to a selected pattern among preset and stored patterns in the storage of the haptic actuator device described below. Accordingly, the user can sense the resistance of the preset pattern by F2 acting in the opposite direction to the action applied by the user.

On the other hand, the haptic actuator according to the present invention can also operate in the vibration mode in addition to the rotation mode described above. That is, the user does not apply the action force P for generating the rotational torque through the rotary knob, but the variation of the current I applied to the core coil in accordance with a predetermined pattern (a magnitude of current and an application period) to a storage unit to be described below. The periodic or aperiodic action of the magnetic attraction force is possible, which can generate vibration in the axial direction of the haptic actuator. Therefore, the user can sense the vibration by the vibration mode through the rotary knob or the haptic housing.

The above-described interpretation of the operation of the rotational mode and the vibrational mode of the haptic actuator is made under a certain condition simplified for ease of explanation, and the present invention is not limited thereto. That is, the above embodiment shows the state of the force on the haptic actuator in the vertical position and used in the torque mode, but Wc and Wd, s when the axis of the haptic actuator operates in a horizontal position on the ground P and F2 may be eliminated if they are removable and have no rotational force by the user and only operate in a vibration mode by magnetic attraction force applied to the core coil, or in some cases more accurate for the force between the rotary core and the rotary disc.

It may take the structure which becomes. The storage unit 7 stores a preset pattern of magnetic attraction force between the core coil (not shown) / rotary core 340 and the rotary suction unit 350, and the numerical value calculated by the calculation unit 4 described below in some cases. It can also perform the function of the buffer unit to temporarily store the.

15 to 18 show examples of preset patterns for the magnetic attraction force between the rotary core 340 and the rotary suction unit 350, which are stored in the storage unit 2, in which the left side of the rotary knob is shown. The pattern of the magnetic attraction force Fd acting according to the rotation angle θ of 300 is shown, and the right side represents the force acting through the rotary knob 300 when an arbitrary constant action force PT is applied by the user. The force (= PT-F2 = PT-μs {Fd + Wc-Wd, s}) is schematically shown. FIG. 15 shows a detent pattern that temporarily increases at a predetermined angular position to allow a user to feel the detent at a predetermined angular position. FIG. 16 shows a constant pattern to which a constant magnetic suction force Fd is applied at all angular positions, and FIG. 17 is greater than any constant action force PT for a rotation angle θ above a predetermined angular position. Fig. 18 shows a barrier pattern which limits the rotation above a predetermined angular position by providing a maximum magnetic attraction force Fd max, and FIG. 18 shows a combination of two or more patterns, i.e., at angular positions A and C. FIG. A compound pattern with a tent pattern and with a barrier pattern at angular position B is shown. A total of four magnetic suction force patterns are illustrated in FIGS. 15 to 18, which are examples of the present invention, and more various patterns may be formed. 15 to 18 illustrate a case in which the rotary switch unit is operated, various magnetic suction force patterns may be formed even when the haptic actuator operates in the vibration mode. For example, when a plurality of maximum magnetic suction forces (Fd max) are applied during a short period, the impact of the rotary core and the rotary disk, and ultimately the fixed plate through the rotary resilient member of the rotary suction / rotary core, may occur. An impact pattern may be formed.

On the other hand, the storage unit 2 according to the present invention is not only a preset pattern for the magnetic attraction force between the rotary core 340 and the rotary suction unit 350 of the haptic actuator, but also a preset pattern, that is, the haptic actuator of the haptic unit and / Alternatively, the operation pattern of the system light emitting unit corresponding to each operation of the capacitive switch unit may be stored in advance. For example, when the haptic actuator forms the detent pattern shown in FIG. 15, the system light emitting source of the system light emitting part generates blue light, and when the haptic actuator forms the constant pattern shown in FIG. 16, the system light emitting source of the system light emitting part. When the white light is generated and the barrier pattern shown in FIG. 17 is formed, the system light emitting source of the system light emitting unit generates red light, and when the complex pattern shown in FIG. 18 is formed, the system light emitting source is the system light emitting unit. The system light emitting unit may output light of a color corresponding to the operation of each haptic unit, such as to generate purple light.

In addition, the operation of the system light emitting unit corresponding to the operation of the haptic unit stored in the storage unit 2 may include a flick operation (blink operation). When each of the magnetic attraction patterns of FIGS. 15 to 18 is set corresponding to each operation mode of the haptic switch unit including the capacitive switch unit described below, the system light emitting unit selects the system light source of the corresponding color when selecting each mode. The number of flicks or the flick period of the flick operation for turning ON and indicating whether the selection is completed when the corresponding mode is selected may be pre-stored in the storage unit 2. The flick operation may take the structure of executing several fast blinks at the time of mode selection and blinking at regular intervals during each mode execution. For example, if the volume switch button 71-8 of the capacitive switch unit to be operated during the audio mode operation is selected, the capacitive switch transmits an input signal to the system control unit 6 and the system control unit 6 stores it. The magnetic attraction force signal corresponding to the corresponding volume operation mode preset and stored in the unit (2) is transmitted to the haptic actuator and the control signal for the operation of the system light emitting unit to the system light source, and the system light source is green according to the control signal. Emits light. The green light emission of the system light source causes two rapid blinks when the volume mode is selected and then stays lit. When the user rotates the rotary knob 300 of the haptic actuator, a change in the electrical signal due to the rotation is transmitted to the system control unit 6, and the system control unit 6 can correspondingly let the user know that the volume mode is performed. So that it blinks in a preset cycle of green light. When the operation of the haptic actuator via the rotary knob 300 ends, the system controller 6 keeps the green light on, and further rotary knob manipulation by the user for a preset input time stored in the storage unit 2. If not, the system controller 6 may turn off the green light of the system light emitting source and emit orange light corresponding to the previous audio mode so that the user can recognize the audio mode operation state. That is, when a predetermined operation mode for the haptic switch unit is selected and performed by the user, the system controller 6 applies a control signal corresponding to a pre-stored flick operation to the storage unit 2 to generate a system light source. In addition to the emission of light of the corresponding color can also perform a flick operation through the on / off control.

The calculating unit 8 makes electrical communication with the system control unit 6 described below and calculates an electrical signal to be applied to the core coil. That is, when the haptic actuator is in the rotation mode, the calculation unit 2 refers to the preset pattern of the magnetic suction force stored in the storage unit 7 transmitted from the system control unit 6, and the rotation detection unit 500 (FIGS. 7 and 8). Based on the amount of rotation of the rotary knob, and ultimately, the rotary disk 355 (see FIG. 7), the applied current I required to apply a predetermined magnetic attraction force is calculated. The system control unit 6 makes electrical communication with the rotation detecting unit 600, the storage unit 2, the calculating unit 4, and the core coil, and applies the applied current I calculated from the calculating unit 4 to the core coil. In addition, for the haptic actuator device, the mode selected by the user among the rotation mode and the vibration mode is determined.

The system controller 6 may also be in electrical communication with the capacitive switch unit 70. FIG. 23 is a schematic plan view of the system housing 50 of the present invention, wherein the system housing body 500 includes a plurality of capacitive switch buttons 71-1, 71-2, 71-3, 71-4, 71-5,71-6,71-7,71-8). Each capacitive switch button has an HVAC switch button 71-1, a seat control switch button 71-2, an enter switch button 71-3, an exit / menu switch button 71-4, a navigation switch button ( 71-5), DMB switch button 71-6, audio switch button 71-7, volume switch button 71-8, or the like.

When power is applied to the sensation system 2, the system display 3 of the sensation system 2 shows an exemplary user interface as shown in FIGS. 24 and 25, which is displayed on the system display 2 as a user interface. The screen is centered around the display of the haptic actuators and an icon indicating the operation mode of each capacitive switch is displayed on the outside thereof. When the user operates each capacitive switch button, the operating state of the changed capacitive switch unit is changed and the electrical signal generated is transmitted to the system control unit 6, and the system control unit 6 is connected to the respective capacitive switch unit. The system display 3 displays an image corresponding to the operation mode. For example, the HVAC switch button 71-1, the volume switch button 71-8, the seat control switch button 71-2, and the navigation switch provided in the capacitive switch unit included in the haptic switch unit. When operating the button 71-5, the system control unit 6 displays the HVAC user interface, audio volume user interface, seat control user interface, navigation, and the like on the system display 3 as shown in Figs. 26, 27, 28, and 29. Display the user interface respectively. Meanwhile, when two or more capacitive switch buttons are operated at the same time and the system controller 6 detects an electrical signal according to two capacitance changes input simultaneously, the system controller 6 is connected to the system display 3 and the button. The control signal output to the corresponding various devices may be switched to the standby state, thereby preventing malfunction of the corresponding device due to an incorrect operation of the capacitive switch unit. Here, although not clearly shown, the haptic switch unit of the sensation system is provided with a separate temperature and humidity sensor so that information on the external operating environment according to the temperature and humidity of the sensation system is transmitted to the system controller 6 to store the storage unit 7. The process of correcting the dielectric constant of the capacitive electrode according to the stored temperature and humidity environment may be further performed. In addition, the storage unit 7 is pre-stored in the information about the dielectric constant according to a number of environments, through the appropriate correction process according to the operating environment of the capacitive switch, a structure that can determine whether the capacitive switch more accurate operating state You can also take

Then, when the user operates the haptic actuator 1 (see FIG. 2), the rotation signal is transmitted to the system control unit 6 through the rotation detection unit, and in some cases, the button operation according to the operation of the button switch unit 20. The signal is transmitted to the system control unit 6. The system control unit 6 transmits a control signal corresponding to a rotation signal or a button manipulation signal through electrical communication with the storage unit 7 and the calculation unit 8, respectively, and an audio device (not shown). ), Each device is controlled by transmission to a seat electric motor (not shown) and a navigation device (not shown). During this process, the system control unit 6 that receives the rotation signal transfers a current as a control signal for operating the rotary switch unit 30 to the core coil of the rotary switch unit 30 according to a pattern stored in the storage unit 6. By transmitting, by operating the rotary switch unit 30 can provide a sense of detent to the user to rotate the rotary knob, the system light emitting source of the system light emitting unit 80 in response to a control signal from the system control unit 6 On / Off control of (81,82,87,89) is performed to allow preset color and / or flick motion control for the mode to allow the user to more easily and quickly recognize the operating modes and operating states performed. Make it possible. In addition, each of these operating states is transmitted to the system display 3 to adjust the air volume of the HVAC, increase the audio volume, increase the seat inclining operation and forward and backward, as shown in Figs. 27, 29, 31 and 32, 34, Each operation state such as navigation search or the like is displayed on the image.

 In the control process for each device through such a series of user interfaces, the system control unit 6 may output the respective control effect sounds to the sound unit 9 so that the user may easily know the operation mode. The sound unit 9 is in electrical communication with the system control unit 6, and the sound corresponding to each operation of the haptic switch unit 5 according to the control signal of the system control unit 6 in conjunction with the haptic switch unit 5. Can output a signal. The storage unit 2 pre-stores sound data corresponding to each operation mode and various operations of the modes.

For example, if the volume switch button 71-8 of the capacitive switch unit to be operated during the audio mode operation is selected, the capacitive switch transmits an input signal to the system control unit 6 and the system control unit 6 stores it. In addition to transmitting the magnetic attraction force signal corresponding to the volume operation mode preset and stored in the unit 2 to the haptic actuator and the control signal for the operation of the system light emitting unit to the system light source, the acoustic data corresponding to the volume operation mode. The sound control signal is transmitted to the sound unit 9 on the basis of the control unit, and the sound unit outputs the sound signal according to the control signal. The green light emission of the system light source makes two fast flashes when the volume mode is selected and stays lit afterwards, and the sound corresponding to the selection of the volume operation mode is repeated two times and then a sound such as "volume control mode". Output the signal. Here, although not clearly shown, a separate digital signal processor (DSP) may be further provided for outputting such a sound signal.

When the user rotates the rotary knob 300 of the haptic actuator, a change in the electrical signal due to the rotation is transmitted to the system control unit 6, and the system control unit 6 can correspondingly let the user know that the volume mode is performed. It blinks at a preset period of green light so that certain beeps are repeated periodically. Of course, as the rotary knob 300 rotates, an electrical signal for increasing or decreasing the volume is transmitted to an audio output unit such as a speaker (not shown), so that the volume of the speaker is increased or decreased. When the operation of the haptic actuator through the rotary knob 300 is terminated and there is no further rotary knob operation by the user for a preset input time stored in the storage unit 2, the system controller 6 turns the green light of the system light source. It turns off and emits an orange light corresponding to the previous audio mode, and at the same time outputs a sound signal such as "audio mode" upon returning to the previous audio mode so that the user can recognize the audio mode operation state.

In addition, the sensation system 2 may perform signal transmission / reception with an external device through the signal output unit 9a, and update the navigation map information stored in the storage unit 7 through the signal output unit 9a, or Various operation processes may be performed, such as downloading the latest music file, and correspondingly, the system light emitting unit and / or sound unit outputs light and / or sound signals for operating the corresponding mode, thereby tactile sensation by the haptic actuator. In addition to sensing, it is also possible to increase the user's cognitive availability through vision and / or hearing, making it easier to recognize the operating state of the sensation system.
