At this time, a plurality of touch buttons 200 may be provided on the steering wheel 100 as shown in the drawing. The vibrating body 250 is shown as being provided at the center of the steering wheel 100, but a plurality of vibrating bodies 250 may be provided on the spokes of the steering wheel 100. In addition, although not shown in the drawing, the steering wheel 100 according to one embodiment may include a control unit 300, an input unit 400, and a storage unit 500.

Hereinafter, the configuration of the touch button 200, the touch area (A), and the distance (D) at which the touch button 200 is pressed will be described with reference to FIG. 3. Figure 3 is a diagram showing the configuration of the touch button 200 according to one embodiment.

Referring to FIG. 3, the touch button 200 according to one embodiment is a touch pad 210 that receives a user's touch command, between the touch pad 210 and a printed circuit board (PCB) 230. Includes a printed circuit board 230 that contains various circuit devices such as a rubber 220, a microcomputer, and active elements, and a contact 240 placed between the rubber 220 and the printed circuit board 230. can do.

The touch pad 210 according to one embodiment may be a capacitive touch pad 210, and the capacitance of the point where the finger touches may change depending on the user's touch, so that the touch pad 210 may be a capacitive touch pad 210 according to the user's touch command input. The coordinates, area (A), and holding time of the touch can be transmitted to the control unit 300. At this time, the control unit 300 may be implemented as a printed circuit board 230 shown in the drawing, but is not limited thereto.

The rubber 220 according to one embodiment serves to maintain a constant distance between the touch pad 210 and the printed circuit board 230 when the user does not press the touch button 200, and the rubber 220 Depending on the shape and material, the feeling the user feels when touching the button may vary.

The printed circuit board 230 according to one embodiment can receive information about the touch, such as the user's touch coordinates, touch area (A), and touch maintenance time, from the touch pad 210, and the received touch area (A). ), the distance at which the touch button 200 is pressed can be determined. Specifically, a predetermined distance corresponding to the touch area (A) may be determined as the distance (D) at which the touch button 200 is pressed. Additionally, a vibration pattern corresponding to the determined pressed distance D may be determined, and a signal for controlling the vibrating body 250 to output the determined vibration pattern may be generated.

The contact point 240 according to one embodiment is a conductor and may be disposed between the rubber 220 and the printed circuit board 230.

Hereinafter, a predetermined distance corresponding to the distance D at which the touch button 200 is pressed will be described with reference to FIG. 4 . Figure 4 is a graph showing the pressed distance corresponding to the touch area according to one embodiment.

Referring to FIG. 4, the process of determining the button press distance (D) can be confirmed by using the fact that the touch area (A) tends to increase in proportion to the button press distance (D). As shown in Figure 4, the button-pressed distance (D) tends to be proportional to the touch area (A) and can simply be defined as a linear function (tendency before compensation), but for practical use, repetitive measurements are required. The graph can be corrected and used through . In other words, if you look at the trend after correction, you can see that the button-pressed distance (D) is proportional to the touch area (A), but is not defined as a linear function. Based on a graph with a trend after correction through measurement, the control unit 300 may determine a predetermined distance corresponding to the touch area (A) of the input touch command as the distance (D) at which the touch button 200 is pressed, , Such a graph or a look-up table corresponding to the graph may be stored in the storage unit 500.

Hereinafter, with reference to FIG. 5 , it will be described how the control unit 300 determines whether to input a touch command based on the area (A) and retention time of the touch input to the touch button 200.

As shown in FIG. 5 , the control unit 300 may determine whether to input a touch command based on the area (A) and retention time of the touch input to the touch button 200. At this time, the control unit 300 determines that the area (A) of the touch input to the touch button 200 is greater than or equal to a predetermined area (DA) and that the maintenance time of the touch input to the touch button 200 is a predetermined time (DT). ) or more, it can be determined that a touch command has been input.

In other words, if the touch area (A) is greater than the predetermined area (DA) but the touch maintenance time is shorter than the predetermined time (DT), the control unit 300 may determine that there is no touch command input, and the touch will be maintained. If the time is more than the predetermined time (DT) but the touch area (A) is less than the predetermined area (DA), the control unit 300 may determine that there is no touch command input. This predetermined area (DA) and predetermined time (DT) can be determined through repeated measurements for practical use, and the predetermined area (DA) is determined when the left or right thumb of a typical adult touches the button 200. It can be determined by the average area when touched without pressing . This predetermined area (DA) or predetermined time (DT) may be stored in the storage unit 500. Because of this, it is possible to prevent a touch command from being input when the user accidentally presses the touch button 200.

Below, the advantages of utilizing the vehicle 10 or the steering wheel 100 according to an embodiment will be described with reference to FIG. 6 . Figure 6 is a diagram showing a corrected F-S diagram according to one embodiment.

By using the vehicle 10 or the steering wheel 100 according to an embodiment, the F-S diagram (F: button repulsion force, S: button pressed distance) can be corrected. The F-S diagram is an indicator used in device design. It measures the repulsion force of the button per the distance (D) at which the button is pressed while pressing the touch button 200 with equipment that can measure pressure (e.g., a pressure sensor). It quantitatively expresses the touch feeling of the button. The F-S diagram is determined by the shape and material of the components constituting the touch button 200, and the trend of the diagram does not change unless the configuration of the touch button 200 is changed.

However, according to the vehicle 10 or the steering wheel 100 according to one embodiment, the button-pressed distance (D), which is a parameter of the F-S diagram index, can be known, so the vibrating body 250 at a predetermined pressed distance By changing the vibration pattern, it is possible to correct the button repulsion force at a predetermined pressed distance. Through this, the vehicle 10 or the steering wheel 100 according to one embodiment can correct the mechanically fixed F-S diagram.
