Further, the right turn signal lamp control button 400 may be provided on the rear portion of the steering wheel 200. The user can conveniently operate the right turn signal control button 400 by using the index finger of the right hand.

 For this purpose, the right turn signal control button 400 is operated in the center of the rear portion of the steering wheel 200 (here, the center CP of the rear portion and the center CP of the front portion match) 200 at a predetermined height H along the steering wheel 200 in the upward direction.

6, the right turn signal lamp control button 400 includes a first extension line L1 extending in the right direction from the center CP of the steering wheel 200 and a second extension line L1 extending from the center of the steering wheel 200 The angle? ₁ formed by the second extension line L2 extending from the center CP to the point at which the right turn indicator control button 400 is positioned is set to 10 to 45 degrees. .

When the angle? ₁ formed by the first extension line L1 and the second extension line L2 is equal to or less than 10 degrees, the speed control button 300 is controlled by the user's thumb, It is difficult to adjust the button 400.

When the angle? ₁ between the first extension line L1 and the second extension line L2 is 45 degrees or more, the index finger of the user does not reach the right direction indicator control button 400, It may be impossible to adjust the speed control button 300 and the right turn signal control button 400 at the same time.

In the same effect, the left direction indicator lamp control button 500 can control the left direction indicator provided in the vehicle. The left direction indicator light control button 500 also has a center CP of the rear portion of the steering wheel 200 in which the center CP of the rear portion and the center CP of the front portion, May be provided at a predetermined height in the upward direction along the steering wheel 200 at the distal end in the left direction.

More specifically, the left turn indicator lamp control button 500 is operated by a third extension line extending in the left direction from the center CP of the steering wheel 200 and a second extension line extending from the center of the steering wheel 200, And an angle formed by a fourth extension line extended to a point where the first steering wheel 500 is located is 10 ° to 45 °.

[Table 1] summarizes the control status of the vehicle and the like in accordance with the event of operating the right direction indicator light control button 400 and the left direction indicator light control button 500.

event Whether the push signal is received Vehicle light control One When the right turn signal lamp control button 400 receives the push signal Right turn indicator flashing 2 When the left turn signal lamp control button 500 receives the push signal Left direction indicator flashing 3 When the right direction indicator light control button 400 and the left direction indicator light control button 500 are pressed Emergency flashing

Referring to Table 1, when the right turn signal lamp control button 400 receives the push signal from the user, the right turn signal lamp blinks. When the left turn signal lamp control button 500 receives the push signal from the user, The turn signal lights can be blinking.

When the right direction indicator light control button 400 and the left direction indicator light control button 500 receive the pushing signal from the user at the same time, the emergency light can be blinked.

The right direction indicator light control button 400 and the left direction indicator light control button 500 can be implemented by a toggle button method.

The integrated steering wheel 200 that provides the multi-control function according to an embodiment of the present invention may further include a vibration unit (not shown).

When the vibrating part receives the sensed value from the driver's sleeping recognition sensor provided in the vehicle and the collision recognition sensor provided in the vehicle, the vibrating part can transmit the danger signal to the user by vibrating the steering wheel.

7 is a flowchart illustrating a method of operating a vibration unit according to an embodiment of the present invention.

Referring to FIG. 7, in step S701, a sensed value measured in real time from a sensor provided in a vehicle may be received.

In step S702, it is possible to determine whether the drowsy operation is performed by analyzing the sensed value. If it is determined that the user is driving the sleeping operation, the vibration signal may be transmitted to the user through the vibration unit in step S703.

If it is determined that the user is not sleeping in step S702, it may be determined in step S704 whether or not a collision with the vehicle ahead is warned.

If a collision with the next vehicle is required, the emergency light can be blinked in step S705. In addition, in step S706, the vibration signal may be transmitted to the user through the vibration part.

If it is determined in step S704 that the collision with the next vehicle is not necessary, it is possible to determine whether or not the collision with the preceding vehicle is urgent in step S707. If there is a possibility of collision with the vehicle ahead, the vehicle speed may be decelerated in step S708.

Further, in step S709, the emergency light can be blinked. Furthermore, the vibration signal can be transmitted to the user through the vibration part.

When the speed of the vehicle decelerates, the driver intuitively recognizes the vehicle control state through the LED of the display unit 320 of the speed control button 300 of the steering wheel without passing through the separate display device that the current vehicle speed is decelerated Able to know.

If it is necessary to decelerate the speed of the automobile in the case where an emergency occurs in the automobile in step S710, the display unit 320 can be operated even if the speed control button 300 does not receive any one of the upward pressure and the upward pressure from the user. May periodically or non-periodically flicker, thereby notifying the user of the emergency.
