상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.The technical structure described above is a background technique for assisting the understanding of the present invention, and does not mean the prior art widely known in the technical field to which the present invention belongs.

본 발명은 차량속도와 엔진회전수와 외부 우적상황에 따라 차량내 경고음의 볼륨을 가변 출력하도록 한 차량내 경고음의 볼륨 제어 장치 및 방법을 제공하는데 그 목적이 있다.It is an object of the present invention to provide an apparatus and method for controlling the volume of an in-vehicle warning sound so as to variably output the volume of the in-vehicle warning sound according to a vehicle speed, an engine speed, and an external rain situation.

이하, 실시예를 통하여 본 발명을 더욱 상세히 설명하기로 한다. 이들 실시예는 단지 본 발명을 예시하기 위한 것이며, 본 발명의 권리 보호 범위가 이들 실시예에 의해 제한되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

도 1 은 본 실시예에 의한 차량내 경고음의 볼륨 제어 장치의 블럭도이고, 도 2 는 본 실시예에 의한 차량내 경고음의 볼륨 제어 방법의 순서도이다.1 is a block diagram of a volume control device for in-vehicle warning sounds according to the present embodiment, and FIG. 2 is a flowchart of a method for controlling volume of in-vehicle warning sounds according to the present embodiment.

도 1 내지 도 2를 참고하면, 본 실시예에 의한 차량내 경고음 볼륨 제어 장치는 전장유닛 제어부(1)와 경고음 출력부(2)와 속도센싱부(3)와 엔진회전수 센싱 부(4)와 우적센싱부(5)를 포함한다.1 to 2, the warning sound volume control device in a vehicle according to the present embodiment includes an electric equipment unit control unit 1, an alarm sound output unit 2, a speed sensing unit 3, and an engine speed sensing unit 4. And a raindrop sensing unit 5.

전장유닛 제어부(1)는 속도센싱부(3)와 엔진회전수 센싱부(4)와 우적센싱부(5)로부터 차량속도와 엔진회전수 및 우적센싱신호를 각각 입력받고, 문열림 상태나 안전벨트 상태 등의 경고음 출력 조건이 되면, 차량속도와 엔진회전수와 우적센싱신호에 따라 경고음 볼륨을 가변 출력한다.The electric unit control unit 1 receives a vehicle speed, an engine speed, and a raindrop sensing signal from the speed sensing unit 3, the engine speed sensing unit 4, and the raindrop sensing unit 5, respectively, and the door open state or safety. When a warning sound output condition such as a belt state is reached, the alarm sound volume is variably output according to the vehicle speed, the engine speed, and the rain sensing signal.

여기서, 경고음 볼륨의 가변 출력은 차량속도와 엔진회전수와 우적센싱신호에 따른 가중치를 기본볼륨에 가산하여 가변 출력한다.Here, the variable output of the warning sound volume is variably output by adding the weight according to the vehicle speed, the engine speed, and the raindrop sensing signal to the basic volume.

경고음 출력부(2)는 전장유닛 제어부(1)의 제어를 받아 경고음을 출력한다.The warning sound output unit 2 outputs a warning sound under the control of the electric field unit control unit 1.

예를들면, 기본볼륨에 차량속도, 엔진회전수 및 우적센서 값에 각각 가중치를 곱하여 합산한 값으로 최종 경고음 볼륨을 결정하여 경고음의 볼륨이 차량속도와 엔진회전수 및 우적센싱신호에 연동되도록 한다.For example, the final volume is determined by multiplying the basic volume by the weight of the vehicle speed, engine speed, and rain sensor, respectively, so that the volume of the warning sound is linked to the vehicle speed, engine speed, and raindrop sensing signal. .

경고음 볼륨 = 기본볼륨 + (차량속도×속도가중치)+(엔진회전수×회전수가중치)+(우적센서×우적센서가중치)Beep Volume = Basic Volume + (Vehicle Speed × Speed Weight) + (Engine Speed × Speed Weight) + (Dump Sensor × Drop Weight)

위 수식에 의하면, 차량속도가 0이고, 엔진회전수가 0이며, 비가 안오는 경우는 기본볼륨으로 출력한다.According to the above formula, when the vehicle speed is 0, the engine speed is 0, and there is no rain, it is output as the basic volume.

또한, 차량속도와 엔진회전수와 우적센싱신호에 따른 가중치는 차량 모델별 특성에 맞게 설정한다. 예를들면, 차량속도보다 엔진 회전수의 소음이 차량내부에서 더욱 민감하게 들리는 모델인 경우 엔진 회전수 가중치를 차량속도보다 크게 설정한다.In addition, the weight according to the vehicle speed, the engine speed and the rain sensing signal is set according to the characteristics of each vehicle model. For example, in a model in which the engine speed noise is more sensitive to the vehicle interior than the vehicle speed, the engine speed weight is set to be larger than the vehicle speed.

도 2를 참고하면, 본 실시예에 의한 차량내 경고음 볼륨 제어 방법은 다음과 같다.Referring to Figure 2, the vehicle warning sound volume control method according to the present embodiment is as follows.

먼저 각종 센싱부로부터 차량속도와 엔진회전수와 우적센싱신호를 입력받는다(S1).First, the vehicle speed, the engine speed, and the rain sensing signal are received from various sensing units (S1).

이때, 문열림 상태나 안전벨트 상태 등의 경고음 출력 조건이 되면(S2), 차량속도와 엔진회전수와 우적센싱신호에 따른 가중치를 기본볼륨에 가산하여 경고음을 출력한다(S3). At this time, when the alarm sound output conditions such as the door open state or the seat belt state (S2), the weight of the vehicle speed, the engine speed and the rain sensing signal is added to the basic volume to output the warning sound (S3).

다시 설명하면, 기본볼륨에 차량속도, 엔진회전수 및 우적센서 값에 각각 가중치를 곱하여 합산한 값으로 최종 경고음 볼륨을 결정하여 경고음의 볼륨이 차량속도와 엔진회전수 및 우적센싱신호에 연동되도록 한다.In other words, the final warning sound volume is determined by multiplying the basic volume by the vehicle weight, the engine speed, and the rain sensor value by the weight, so that the volume of the warning sound is linked to the vehicle speed, the engine speed, and the rain sensing signal. .

이와 같이 본 발명은 경고음의 볼륨이 차량속도와 엔진회전수 및 우적 상황에 연동시켜 출력하므로 운전자는 보다 정확히 경고음을 인지할 수 있다.As described above, the present invention outputs the volume of the warning sound in conjunction with the vehicle speed, the engine speed, and the rain situation, so that the driver can recognize the warning sound more accurately.

상술한 바와 같이 본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다. 따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is merely exemplary, and various modifications and equivalent other embodiments of the present invention may be made by those skilled in the art. I understand that it is possible. Therefore, the true technical protection scope of the present invention will be defined by the claims below.
