Description

건설장비의 부저음 제어시스템Buzzer Control System of Construction Equipment
본 발명은 건설장비의 부저음 제어시스템에 관한 것으로서 더욱 상세하게는 계기판에서 출력할 방향 지시등의 소리에 대한 부저음을 계기판과의 사이에 설정된 부저음 프로토콜에 따른 양방향 통신을 통해 마스터 ECU에서 직접 제어하는 건설장비의 부저음 제어시스템에 관한 것이다.The present invention relates to a buzzer control system for construction equipment, and more particularly, to a buzzer for the sound of the direction indicator to be output from the instrument panel, the construction equipment directly controlled by the master ECU through the bidirectional communication according to the buzzer protocol set between the instrument panel The buzzer control system of the present invention.
일반적으로, 차량에는 좌측 방향 지시등과 우측 방향 지시등이 구비되며, 좌측 방향 지시등과 우측 방향 지시등이 함께 점멸하는 경우에는 비상등으로 기능한다. 이러한 방향 지시등은 차량의 진로 방향이나 위급 상황을 다른 차량의 운전자나 보행자에게 시각적으로 표시한다.In general, the vehicle is provided with a left turn indicator and a right turn indicator, and when the left turn indicator and the right turn indicator blink together, they function as emergency lights. These turn signals provide a visual indication of the direction or emergency of a vehicle to drivers or pedestrians of other vehicles.
굴삭기와 같은 건설장비에도 방향 지시등이 설치된다. 이와 같은 건설장비에 설치되어 있는 방향 지시등은 운행 중에는 다른 차량의 운전자나 보행자에게, 작업 중에는 인접 건설장비나 작업자들에게 건설장비의 진로 방향이나 위급 상황을 시각적으로 표시한다. 이때, 방향 지시등의 점멸 상태는 운전석 전방에 마련되어 있는 계기판에도 표시되어 운전자에게도 시각적으로 인지시키게 된다. 하지만, 건설장비를 운전하여 주행하는 중이거나 각종 레버를 조작하여 작업하는 경우에는, 전방 주시로 인해, 운전자가 차량의 현재 정보가 표시되는 계기판을 계속적으로 관찰하기는 쉽지 않다. 즉, 운전자가 방향 지시등을 켜고, 이에 따라, 계기판에 방향 지시등 점멸 상태가 표시되더라도 운전자가 계기판을 응시하여 눈으로 확인하지 않는 이상, 제대로 작동되었는지 확인하기 어렵다. 그래서, 일반적인 차량이나 건설장비에서는 방향 지시등 점멸을 계기판에 표시함과 아울러, 이에 대한 소리를 출력하여, 방향 지시등에 대한 시각적 표시와 청각적 표시를 운전자에게 동시에 제공한다.Directional indicators are also installed on construction equipment such as excavators. The direction indicator installed in such construction equipment visually displays the direction or emergency of the construction equipment to the driver or pedestrian of another vehicle while driving and to the adjacent construction equipment or workers during work. At this time, the blinking state of the direction indicator is displayed on the instrument panel provided in front of the driver's seat to visually recognize the driver. However, when driving by driving construction equipment or operating by operating various levers, it is not easy for the driver to continuously observe the instrument panel on which the current information of the vehicle is displayed due to the forward look. That is, even if the driver turns on the turn signal and accordingly, the blinking state of the turn indicator is displayed on the instrument panel, it is difficult to confirm whether the driver operates properly unless the driver stares at the instrument panel and visually confirms it. Thus, in a typical vehicle or construction equipment, the indicator flashes on the instrument panel and also outputs a sound, thereby providing the driver with a visual indication of the direction indicator and an audio indication at the same time.
종래의 건설장비에서는 릴레이(relay)를 이용하여 기계음으로 방향 지시등 소리를 출력하거나 방향 지시등 소리를 출력하는 독립적인 회로를 갖는 계기판이 직접 외부 입력(digital input)을 받아 자체적으로 방향 지시등 소리를 출력하였다. 그러나 릴레이를 이용하여 기계음으로 방향 지시등 소리를 출력하는 종래의 방식은 방향 지시등 소리를 출력하기 위한 릴레이와 같은 전장 부품이 추가되어야 하므로, 제조 비용이 증가하는 문제가 있었다. 또한, 독립적인 출력 회로를 갖는 계기판을 구비하는 경우에는 방향 지시등 소리에 대한 사양 변경이 요구될 시 계기판의 소프트웨이에 내장된 소리의 음색이나 길이 등을 변경해야 하기 때문에 계기판의 ECU를 수거 및 교체해주어야 하는 불편함이 있었다.In the conventional construction equipment, an instrument panel having an independent circuit for outputting a turn signal sound to a mechanical sound or a turn signal sound using a relay receives a digital input directly and outputs a turn signal sound itself. . However, the conventional method of outputting the turn signal sound to the machine sound using the relay, there is a problem that the manufacturing cost increases because electrical components such as a relay for outputting the turn signal sound has to be added. In addition, when an instrument panel with an independent output circuit is provided, when the specification of the direction indicator sound is required, the tone or length of the sound embedded in the instrument software must be changed. There was an inconvenience to be done.
본 발명은 상술한 바와 같은 종래기술의 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 계기판에서 출력할 방향 지시등의 소리에 대한 부저음을 계기판과의 사이에 설정된 부저음 프로토콜에 따른 양방향 통신을 통해 마스터 ECU에서 직접 제어하는 건설장비의 부저음 제어시스템을 제공하는 것이다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention through the two-way communication according to the buzzer protocol set between the instrument panel and the buzzer for the sound of the direction indicator to be output from the instrument panel It is to provide the buzzer control system of construction equipment directly controlled by the master ECU.
이를 위해, 본 발명은, 마스터 ECU; 및 상기 마스터 ECU와의 사이에 설정된 부저음 프로토콜에 따라 상기 마스터 ECU로부터 전송되는 부저음 출력 신호를 수신하며, 상기 부저음 출력 신호가 수신되면, 상기 부저음 출력 신호에 따른 부저음을 외부에 출력하는 계기판을 포함하는 건설장비의 부저음 제어시스템을 제공한다.To this end, the present invention, the master ECU; And an instrument panel configured to receive a buzzer output signal transmitted from the master ECU according to the buzzer protocol set between the master ECU and output the buzzer sound according to the buzzer output signal when the buzzer output signal is received. Provides a buzzer control system for equipment.
여기서, 상기 계기판은 상기 부저음 출력 여부를 상기 마스터 ECU에 응답할 수 있다.Here, the instrument panel may respond to the master ECU whether the buzzer sound is output.
이때, 상기 계기판은 상기 부저음 출력 후 상기 마스터 ECU에 "acknowledge" 신호를 전송하는 방식으로 응답할 수 있다.In this case, the instrument panel may respond by transmitting an "acknowledge" signal to the master ECU after the buzzer sound is output.
또한, 상기 계기판은 상기 부저음을 출력하지 못한 경우, 상기 마스터 ECU에 "failure" 신호를 전송하는 방식으로 응답할 수 있다.In addition, when the instrument panel fails to output the buzzer sound, the instrument panel may respond by transmitting a "failure" signal to the master ECU.
그리고 상기 마스터 ECU는 상기 계기판으로부터 "failure" 신호를 수신하면, 상기 부저음 출력 신호와 동일한 부저음 출력 신호를 재차 상기 계기판에 전송할 수 있다.When the master ECU receives the "failure" signal from the instrument panel, the master ECU may transmit the same buzzer output signal to the instrument panel again.
또한, 상기 마스터 ECU는, 운전자의 조작에 의해 방향 지시등에 대한 점등 신호가 입력되면, 상기 방향 지시등에 대한 소리를 출력하는 상기 부저음의 유형을 설정한 후 상기 부저음의 유형에 따른 상기 부저음 출력 신호를 출력하여 상기 계기판으로 전송할 수 있다.In addition, when the lighting signal for the turn signal is input by the driver's operation, the master ECU sets the type of the buzzer sound for outputting the sound for the turn signal and then outputs the buzzer sound signal according to the type of the buzzer sound. The output can be sent to the instrument panel.
그리고 상기 마스터 ECU와 상기 계기판은 CAN 통신 또는 SPI 통신을 통해 양방향 통신할 수 있다.The master ECU and the instrument panel may bidirectionally communicate through CAN communication or SPI communication.
또한, 상기 부저음 출력 신호는 상기 부저음의 크기, 음색, 횟수, 시작 시간, 종료 시간 및 지속 시간을 포함할 수 있다.The buzzer output signal may include the size, tone, frequency, start time, end time, and duration of the buzzer sound.
본 발명에 따르면, 계기판에서 출력될 방향 지시등의 소리에 대한 부저음을 계기판과의 사이에 설정된 부저음 프로토콜에 따른 통신을 통해 마스터 ECU에서 직접 제어함으로써, 전장 부품을 이용하여 기계음으로 방향 지시등의 소리를 출력하던 종래의 출력 방식보다 제조 원가를 절감할 수 있다.According to the present invention, the buzzer for the sound of the direction indicator to be output from the instrument panel is directly controlled by the master ECU through the communication according to the buzzer protocol set between the instrument panel, thereby outputting the sound of the direction indicator to the machine sound using the electrical components It is possible to reduce the manufacturing cost than the conventional output method.
또한, 본 발명에 따르면, 부저음의 길이나 음색이 변경되더라도 마스터 ECU 레벨에서 제어가 가능함으로써, 계기판의 소프트웨어를 수정할 필요가 없다.In addition, according to the present invention, even if the length or tone of the buzzer is changed, it is possible to control at the master ECU level, thereby eliminating the need to modify the software of the instrument cluster.
즉, 본 발명에 따르면, 현장에서의 대응이 쉽고, 유지보수 비용 또한 줄일 수 있다.That is, according to the present invention, the on-site response is easy, and the maintenance cost can also be reduced.
도 1은 본 발명의 실시 예에 따른 건설장비의 부저음 제어시스템을 설명하기 위한 모식도.1 is a schematic diagram for explaining a buzzer control system of construction equipment according to an embodiment of the present invention.
이하에서는 첨부된 도면들을 참조하여 본 발명의 실시 예에 따른 건설장비의 부저음 제어시스템에 대해 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail for the buzzer control system of construction equipment according to an embodiment of the present invention.
아울러, 본 발명을 설명함에 있어서, 관련된 공지 기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단된 경우 그 상세한 설명은 생략한다.In addition, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
도 1에 도시한 바와 같이, 본 발명의 실시 예에 따른 부저음 제어시스템(100)은 예컨대, 굴삭기와 같은 건설장비를 운전하는 운전자가 건설장비의 방향 전환이나 위급 상황을 주변에 알리기 위해 방향 지시등을 점등 혹은 점멸시키기 위한 레버 조작을 하는 경우, 방향 지시등의 점등 상태를 청각적으로 알리기 위해 방향 지시등의 점등에 따른 부저음을 출력하는 제어시스템이다.As shown in Figure 1, the buzzer sound control system 100 according to an embodiment of the present invention, for example, a driver operating a construction equipment such as an excavator to turn the direction of the construction equipment or emergency situation to inform the surrounding signal When the lever operation for lighting or flashing is performed, it is a control system that outputs a buzzer sound according to the lighting of the turn signal to audibly inform the lighting state of the turn signal.
이러한 부저음 제어시스템(100)은 마스터 ECU(110) 및 계기판(120)을 포함하여 형성된다.The buzzer control system 100 includes a master ECU 110 and an instrument panel 120.
마스터 ECU(electronic control unit)(110)는 예컨대, 굴삭기의 하부 주행체의 주행 제어를 위한 ECU, 상부 선회체의 선회 장치 제어를 위한 ECU, 붐, 아암, 버킷 등과 같은 작업 장치 제어를 위한 ECU 등과 같이, 굴삭기의 전자 제어를 위해 설치되는 다수 개의 ECU를 총칭한다.The master electronic control unit 110 includes, for example, an ECU for driving control of a lower traveling body of an excavator, an ECU for controlling a turning device of an upper swinging body, an ECU for working device control such as a boom, an arm, a bucket, and the like. Similarly, a plurality of ECUs installed for the electronic control of the excavator is collectively.
본 발명의 실시 예에 따른 마스터 ECU(110)는 계기판(120)에서 출력될 방향 지시등의 점등 상태를 소리로 나타내는 부저음을 직접 제어한다. 이를 위해, 마스터 ECU(110)와 계기판(120) 사이에는 부저음 프로토콜(protocol)이 설정되어 있고, 마스터 ECU(110)는 이러한 부저음 프로토콜에 따라 계기판(120)으로 부저음 출력 신호를 전송한다. 또한, 마스터 ECU(110)는 계기판(120)으로부터 부저음 출력 여부에 관한 정보를 수신하여, 부저음 출력 신호를 계속 전송할지 결정한다. 이와 같이, 마스터 ECU(110)는 계기판(120)과 부저음 출력에 관한 신호나 정보를 주고 받게 되는데, 이에 대해서는 하기에서 보다 상세히 설명하기로 한다.The master ECU 110 according to an embodiment of the present invention directly controls a buzzer sound indicating a lighting state of a direction indicator to be output from the instrument panel 120. To this end, a buzzer protocol is set between the master ECU 110 and the instrument panel 120, and the master ECU 110 transmits a buzzer output signal to the instrument panel 120 according to the buzzer protocol. In addition, the master ECU 110 receives information on whether or not the buzzer sound output from the instrument panel 120, and determines whether to continue to transmit the buzzer output signal. As such, the master ECU 110 exchanges a signal or information regarding the buzzer output with the instrument panel 120, which will be described in more detail below.
예를 들어, 마스터 ECU(110)는 CAN(controller area network) 통신 또는 SPI(serial peripheral interface) 통신을 통해 계기판(120)과 양방향 통신을 하며 부저음 출력에 관한 신호나 정보를 주고 받게 된다. 하지만, 이는 하나의 예시일 뿐, 본 발명의 실시 예에 따른 마스터 ECU(110)와 계기판(120) 간의 통신 방식이 이에 한정되는 것은 아니다.For example, the master ECU 110 bidirectionally communicates with the instrument panel 120 through controller area network (CAN) communication or serial peripheral interface (SPI) communication, and transmits or receives a signal or information regarding a buzzer output. However, this is only one example, and the communication scheme between the master ECU 110 and the instrument panel 120 according to an embodiment of the present invention is not limited thereto.
상술한 바와 같이, 마스터 ECU(110)가 계기판(120)에서, 혹은 계기판(120)을 통해 출력될 방향 지시등의 소리에 대한 부저음을 계기판(120)과의 사이에 설정된 부저음 프로토콜에 따른 양방향 통신을 통해 직접 제어하게 되면, 방향 지시등의 소리를 기계음으로 출력하기 위해 종래에 사용되던 릴레이와 같은 전장 부품을 생략할 수 있게 된다. 전장 부품의 생략은 제조 원자 혹은 제조 비용의 절감으로 이어지게 된다.As described above, the master ECU 110 performs the bidirectional communication according to the buzzer protocol set between the instrument panel 120 and the instrument panel 120 with respect to the sound of the direction indicator to be output through the instrument panel 120. If directly controlled through, it is possible to omit the electrical components, such as a relay that is conventionally used to output the sound of the turn signal to the machine sound. Omission of electrical components leads to reductions in manufacturing atoms or manufacturing costs.
이하, 본 발명의 실시 예에 따른 마스터 ECU의 작용에 대해 간단히 설명하기로 한다. 굴삭기와 같은 건설장비를 운전하는 운전자의 조작에 의해 방향 지시등에 대한 점등 신호가 마스터 ECU(110)에 입력되면, 마스터 ECU(110)는 먼저, 방향 지시등에 대한 소리를 출력하는 부저음의 유형을 설정한다. 그 다음, 마스터 ECU(110)는 설정된 부저음의 유형에 따른 부저음 출력 신호를 출력한 후, 출력된 부저음 출력 신호를 부저음 프로토콜에 따른 양방향 통신을 통해 계기판(120)으로 전송한다. 여기서, 부저음 출력 신호는 부저음의 크기, 음색, 횟수, 시작 시간, 종료 시간 및 지속 시간을 포함할 수 있다.Hereinafter, the operation of the master ECU according to an embodiment of the present invention will be briefly described. When the lighting signal for the turn signal is input to the master ECU 110 by the operation of a driver operating construction equipment such as an excavator, the master ECU 110 first sets the type of the buzzer sound outputting the sound for the turn signal. do. Then, the master ECU 110 outputs the buzzer output signal according to the type of the buzzer sound, and then transmits the output buzzer output signal to the instrument panel 120 through bidirectional communication according to the buzzer protocol. Here, the buzzer output signal may include the size, tone, frequency, start time, end time, and duration of the buzzer sound.
계기판(120)은 마스터 ECU(110)에 의해 직접 제어되는 부저음을 외부로 출력한다. 또한, 계기판(120)은 방향 지시등의 점등 상태를 도형이나 부호 등을 이용하여 시각적으로 디스플레이 한다. 즉, 계기판(120)은 방향 지시등의 점등 상태에 대한 시각적 표시와 청각적 표시를 운전자에게 동시에 제공한다.The instrument panel 120 outputs the buzzer sound directly controlled by the master ECU 110 to the outside. In addition, the instrument panel 120 visually displays the lighting state of the direction indicator by using a figure or a sign. That is, the instrument panel 120 provides the driver with a visual indication of the lighting state of the turn signal and an audio indication at the same time.
본 발명의 실시 예에서, 방향 지시등의 점등 상태를 청각적으로 표시하는 부저음을 출력하기 위해, 계기판(120)은 마스터 ECU(110)와의 사이에 설정된 부저음 프로토콜에 따라 마스터 ECU(110)로부터 전송되는 부저음 출력 신호를 수신한다. 상술했듯이, 계기판(120)은 마스터 ECU(110)와의 CAN 통신 또는 SPI 통신을 통해 부저음 출력 신호를 마스터 ECU(110)로부터 수신할 수 있다.In an embodiment of the present invention, the instrument panel 120 is transmitted from the master ECU 110 in accordance with the buzzer protocol set between the master ECU 110 to output the buzzer sound that audibly displays the lighting state of the turn signal. Receive the buzzer output signal. As described above, the instrument panel 120 may receive a buzzer output signal from the master ECU 110 through CAN communication or SPI communication with the master ECU 110.
본 발명의 실시 예에서, 마스터 ECU(110)로부터 부저음의 크기, 음색, 횟수, 시작 시간, 종료 시간 및 지속 시간을 포함하는 부저음 출력 신호를 계기판(120)이 전송 받으면, 계기판(120)은 부저음 출력 신호에 따른 부저음을 전달받은 그대로 외부에 출력한다. 즉, 본 발명의 실시 예에서는 마스터 ECU(110)가 부저음을 직접적으로 제어함에 따라, 계기판(120)은 마스터 ECU(110)의 명령에 따라 단순히 부저음을 출력하는 출력수단으로서만 기능하게 된다. 이에 따라, 본 발명의 실시 예에 따른 부저음 제어시스템(100)을 운용하는 중에, 예컨대, 부저음의 길이, 즉, 부저음의 지속 시간이나 음색을 변경하고자 하는 경우, 계기판(120)과 상관 없이 마스터 ECU(110) 레벨에서, 계기판(120)을 통해 출력될 부저음을 변경하는 것이 가능해진다. 여기서, 방향 지시등의 점등 상태를 시각적으로 표시하는 계기판(120)의 기능은 별도의 통상적인 제어 방식을 통해 구현될 수 있으므로, 이에 대한 설명은 생략하기로 한다.In the embodiment of the present invention, when the instrument panel 120 receives the buzzer output signal including the magnitude, tone, number, start time, end time, and duration of the buzzer sound from the master ECU 110, the instrument panel 120 receives the buzzer sound. Outputs the buzzer sound according to the output signal as it is received. That is, in the embodiment of the present invention, as the master ECU 110 directly controls the buzzer sound, the instrument panel 120 functions only as an output means for simply outputting the buzzer sound according to the command of the master ECU 110. Accordingly, during operation of the buzzer control system 100 according to an embodiment of the present invention, for example, when the length of the buzzer sound, that is, the duration or tone of the buzzer sound is to be changed, the master ECU is irrespective of the instrument panel 120. At the 110 level, it becomes possible to change the buzzer sound to be output through the instrument panel 120. Here, the function of the instrument panel 120 to visually display the lighting state of the turn signal may be implemented through a separate conventional control method, a description thereof will be omitted.
예를 들어, 방향 지시등 소리를 출력하기 위한 소프트웨어가 계기판에 내장되어 있는 경우, 부저음을 변경하기 위해서는 소프트웨어를 수정하거나 교체해야만 하는 번거로움이 있다. 하지만, 본 발명의 실시 예와 같이, 계기판(120)과 상관 없이 마스터 ECU(110) 레벨에서 부저음 변경을 직접 제어하게 되면, 부저음 변경이 요구되더라도 계기판(120)의 소프트웨어를 수정할 필요가 없게 되어, 현장에서의 대응이 쉽고, 유지보수 비용 또한 줄일 수 있게 된다.For example, if software for outputting a turn signal sound is embedded in the instrument cluster, it is cumbersome to modify or replace the software to change the buzzer sound. However, as in the embodiment of the present invention, if the buzzer change is directly controlled at the master ECU 110 level irrespective of the instrument panel 120, it is not necessary to modify the software of the instrument panel 120 even if the buzzer change is required. It is easy to respond in the field and maintenance costs can be reduced.
한편, 마스터 ECU(110)가 계기판(120)을 통해 출력되는 부저음을 직접 제어하기 위해서는 계기판(120)을 통해 부저음이 제대로 출력되었는지 파악할 수 있어야 한다. 이를 위해, 본 발명의 실시 예에서는 계기판(120)이 부저음 출력 여부를 마스터 ECU(110)에 응답한다. 이때, 계기판(120)의 부저음 출력 여부에 대한 응답은 부저음 프로토콜에 따른 CAN 통신 또는 SPI 통신을 통해 이루어질 수 있다. 예를 들어, 마스터 ECU(110)로부터 전송 받은 부저음 출력 신호 그대로 계기판(120)을 통해 부저음이 출력된 경우, 계기판(120)은 부저음 출력 후 부저음 프로토콜에 따른 CAN 통신 또는 SPI 통신을 통해 마스터 ECU(110)에 "acknowledge" 신호를 전송하는 방식으로 응답할 수 있다.On the other hand, in order for the master ECU 110 to directly control the buzzer sound output through the instrument panel 120, it should be able to determine whether the buzzer sound is properly output through the instrument panel 120. To this end, in the embodiment of the present invention, the instrument panel 120 responds to the master ECU 110 whether the buzzer is output. In this case, the response of whether the instrument panel 120 outputs the buzzer sound may be made through CAN communication or SPI communication according to the buzzer protocol. For example, when the buzzer sound is output through the instrument panel 120 as it is transmitted from the master ECU 110, the instrument panel 120 outputs the master ECU through the CAN communication or the SPI communication according to the buzzer protocol after the buzzer sound is output. 110), it may respond by sending an "acknowledge" signal.
반면, 마스터 ECU(110)로부터 부저음 출력 신호를 전송 받은 계기판(120)이 부저음을 출력하지 못한 경우, 계기판(120)은 부저음 프로토콜에 따른 CAN 통신 또는 SPI 통신을 통해 마스터 ECU(110)에 "failure" 신호를 전송하는 방식으로 응답할 수 있다. 여기서, 계기판(120)이 부저음을 출력하지 못한 경우는 부저음의 출력 자체가 이루어지지 않은 경우와 출력된 부저음이 마스터 ECU(110)로부터 전송 받은 부저음 출력 신호에 따른 정보와 일부 또는 전부가 상이한 경우를 포함할 수 있다.On the other hand, when the instrument panel 120 receiving the buzzer output signal from the master ECU 110 does not output the buzzer sound, the instrument panel 120 may fail to the master ECU 110 through CAN communication or SPI communication according to the buzzer protocol. Respond by sending a signal. Here, when the instrument panel 120 does not output the buzzer sound, the case where the output of the buzzer sound itself is not made and the case where the output buzzer sound is different from some or all of the information according to the buzzer output signal transmitted from the master ECU 110 are different It may include.
계기판(120)이 부저음을 제대로 출력하지 못한 경우, 계기판(120)으로부터 "failure" 신호를 수신한 마스터 ECU(110)는 최초 부저음 출력 신호와 동일한 부저음 출력 신호를 재차 계기판(120)에 전송하여, 계기판(120)으로 하여금 제대로 된 부저음을 출력하게 한다.When the instrument panel 120 does not output the buzzer sound properly, the master ECU 110 receiving the "failure" signal from the instrument panel 120 transmits the same buzzer output signal to the instrument panel 120 again. The instrument panel 120 outputs the correct buzzer sound.
이와 같이, 마스터 ECU(110)는 부저음 출력 여부에 대한 계기판(120)의 응답을 통해 계기판(120)을 통해 출력되는 부저음을 직접 제어할 수 있고, 부저음 제어에 대한 신뢰성을 확보할 수 있게 된다.As such, the master ECU 110 may directly control the buzzer output through the instrument panel 120 through the response of the instrument panel 120 whether the buzzer sound is output or not, thereby ensuring reliability of the buzzer control.
또한, 상술한 바와 같이, 본 발명의 실시 예에서는 마스터 ECU(110)와 계기판(120)이 상호간에 설정된 부저음 프로토콜에 따른 양방향 통신을 통해 부저음의 크기, 음색, 횟수, 시작 시간, 종료 시간 및 지속 시간을 포함하는 부저음 출력 신호와 부저음 출력 여부에 대한 응답을 주고 받게 된다.In addition, as described above, in the embodiment of the present invention, the master ECU 110 and the instrument panel 120 have the size, tone, number, start time, end time, and duration of the buzzer sound through bidirectional communication according to the buzzer protocol set to each other. A buzzer output signal including time and a response to whether the buzzer is output are exchanged.
이와 같이, 마스터 ECU(110)와 계기판(120) 사이에 부저음 프로토콜을 설정하게 되면, 상기와 같은 신호나 정보에 대한 속성을 확장할 수 있어, 계기판(120)을 통해 출력되는 부저음에 대한 마스터 ECU(110)의 정밀 제어가 가능해진다.As such, when the buzzer protocol is set between the master ECU 110 and the instrument panel 120, the properties of the signals or information as described above can be extended, and the master ECU of the buzzer sound output through the instrument panel 120 can be extended. Precision control of 110 becomes possible.
이상과 같이 본 발명은 비록 한정된 실시 예와 도면에 의해 설명되었으나, 본 발명은 상기의 실시 예에 한정되는 것은 아니며, 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 이러한 기재로부터 다양한 수정 및 변형이 가능하다.As described above, although the present invention has been described with reference to the limited embodiments and the drawings, the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from such descriptions.
