Abstract

A method for reporting an operating state of a high voltage battery relay for a vehicle is provided not to use a sound insulation material for shielding an operation sound of a relay by recognizing the operation sound of the relay as a normal operation sound. A relay for a high voltage battery operates a high voltage battery system by a car control unit. The car control unit determined whether or not a key starting state is triggered(S100). If the key starting state is triggered, the car control unit generates a relay 'ON' command(S200). When the relay 'ON' command is generated, an operation of the relay is notified to a driver(S300). After notifying the operation of the relay to the driver, the relay is turned-on(S400). When the relay is turned-on, the notifying state is canceled(S500). When the car control unit dose not perform the relay 'ON' command, it is determined whether or not the car control unit generates a relay 'OFF' command(S210). When the 'OFF' command is generated, the relay OFF is notified to the driver(S230). After notifying the relay OFF to the driver, the relay is turned-off.

본 발명은 차량용 고전압 배터리 릴레이의 작동 상태 알림 방법에 관한 것으로, 더욱 상세하게는 고전압 배터리 릴레이의 작동시 생기는 소음을 탑승자가 소음으로 인식하지 않도록 고전압 배터리 릴레이의 동작과 동시에 운전석 클러스터에 지시등 또는 차임벨 알람을 해주어 릴레이 작동 소음을 정상 작동 음으로 인식하도록 하는 차량용 고전압 릴레이의 작동 상태 알림 방법에 관한 것이다.The present invention relates to a method for notifying operation status of a high voltage battery relay for a vehicle, and more particularly, an indicator light or chime alarm to a driver's seat cluster at the same time as the operation of the high voltage battery relay so that passengers do not recognize noise generated when the high voltage battery relay is operated. The present invention relates to a method for notifying operation status of a high voltage relay for a vehicle to recognize the relay operation noise as a normal operation sound.

일반적으로 릴레이의 동작시 단자 연결판이 상하로 움직이면서 작동(on/off) 하기 때문에 동작 소음이 발생한다.In general, when the relay is in operation, the terminal connecting plate moves up and down to turn on / off the operation noise.

그러나 차량의 와이퍼나 방향 지시등과 같은 기구를 작동할 때 릴레이의 작동 소음이 발생해도 탑승자나 운전자는 이를 소음으로 인식하지 않는다. 왜냐하면 이러한 작동음은 운전자가 작동을 지시한 후 와이퍼나 방향 지시등이 정상 작동을 하고 있다는 신호음으로 판단되기 때문이다.However, when operating a device such as a vehicle wiper or turn signal, even if the operating noise of the relay is generated, the passenger or driver does not recognize it as a noise. This is because the operation sound is judged to be a signal that the wiper or the turn signal is operating normally after the driver instructs the operation.

첨부된 도 1은 종래의 고전압 배터리 릴레이의 작동 상태를 도시한 회로도이다.1 is a circuit diagram illustrating an operating state of a conventional high voltage battery relay.

도 1에 도시된 고전압 배터리(1)의 릴레이(10)는 운전자가 아닌 차량 제어 유닛(Vehicle Control Unit, VCU, 20)에 의해 작동되므로 비록 작은 소리라 할지라도 운전자나 탑승객에게 소음으로 인식될 수 있다. 보편적으로 이를 차단하기 위해 차음재를 이용하고 있다.Since the relay 10 of the high voltage battery 1 shown in FIG. 1 is operated by a vehicle control unit (VCU) 20 rather than a driver, even a small sound may be recognized as a noise by a driver or a passenger. have. In general, sound insulation is used to block this.

그러나 릴레이 작동음을 차폐하기 위해 차음재를 사용하는 경우 원가 상승이 야기되며, 고전압 배터리의 작동에 필요한 릴레이가 정상적으로 작동하는지의 여부를 알기 힘든 문제가 있다.However, when the sound insulating material is used to shield the relay operation sound, a cost increase is caused, and it is difficult to know whether the relay required for the operation of the high voltage battery is normally operated.

상기와 같은 문제를 해결하기 위한 본 발명의 목적은, 릴레이의 작동음 발생과 동시에 운전석 클러스터에 지시등 또는 알람으로 이를 알려줌으로써 운전자나 탑승객이 릴레이의 작동음을 정상적인 동작음으로 인식하도록 하는 차량용 고전압 배터리 릴레이의 작동 상태 알림 방법을 제공하는 것이다.An object of the present invention for solving the above problems, the high voltage battery for a vehicle to allow the driver or passengers to recognize the operation sound of the relay as a normal operating sound by informing the driver cluster cluster at the same time as the operation sound of the relay is generated. It is to provide a method of notifying the operation status of the relay.

상기와 같은 목적을 달성하기 위하여, 본 발명은 고전압 배터리 시스템과, 차량제어유닛에 의해 상기 고전압 배터리시스템을 작동시키는 고전압 배터리용 릴레이가 구비된 차량에 있어서, 차량제어유닛에서 키 시동 상태인지 판단하는 단계; 키 시동 상태이면 차량제어유닛이 릴레이 'ON' 명령을 작성하는 단계; 'ON' 명령이 작성되면 운전자에게 릴레이의 작동을 알리는 단계; 운전자에게 알린 후 릴레이를 'ON'하는 단계; 및 릴레이가 'ON'되면 운전자에게 알림 상태를 해제하는 단계를 포함하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a high voltage battery system and a vehicle having a high voltage battery relay for operating the high voltage battery system by a vehicle control unit, the vehicle control unit determines whether the key starting state step; The vehicle control unit issuing a relay 'ON' command if the key is started; Notifying the driver of the operation of the relay when an 'ON' command is generated; 'ON' the relay after notifying the driver; And releasing the notification state to the driver when the relay is 'ON'.

상기 키 시동 상태이면 차량제어유닛이 릴레이 'ON' 명령을 작성하는 단계는 차량제어유닛이 릴레이 'ON' 명령을 작성하지 않았으면 차량제어유닛이 릴레이 'OFF' 명령을 작성하는 단계와, 'OFF' 명령이 작성되면 운전자에게 릴레이 OFF를 알리는 단계와, 운전자에게 알린 후 릴레이를 'OFF'하는 단계를 포함하는 것을 특징으로 한다.If the vehicle control unit writes a relay 'ON' command when the key is started, the vehicle control unit writes a relay 'OFF' command if the vehicle control unit does not write a relay 'ON' command, and 'OFF' It is characterized in that it comprises the step of notifying the driver of the relay OFF when the command is written, and the step of 'off' the relay after notifying the driver.

'ON' 명령이 내려지면 운전자에게 이를 알리는 단계 및 'OFF' 명령이 내려지면 운전자에게 이를 알리는 단계는 운전석 클러스터에 설치되는 지시등 또는 차임벨의 형태로 구현되는 것을 특징으로 한다.The step of informing the driver when the 'ON' command is issued and the step of informing the driver when the 'OFF' command is issued is characterized in that it is implemented in the form of an indicator light or chime bell installed in the driver's cluster.

이하에서는 첨부 도면을 참조하여 본 발명의 일 실시예에 대해 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

첨부된 도 2는 본 발명에 따른 고전압 배터리 릴레이의 작동 상태를 도시한 회로도이고, 도 3은 본 발명의 고전압 배터리 릴레이의 작동 상태에 따른 순서도이다.2 is a circuit diagram illustrating an operating state of the high voltage battery relay according to the present invention, and FIG. 3 is a flowchart according to the operating state of the high voltage battery relay of the present invention.

도 2에 도시된 바와 같이, 본 발명의 고전압 배터리 시스템(100)은 고전압을 출력하는 배터리 시스템을 필요로 하는 연료전지 자동차나 하이브리드 자동차 등에 장착된다.As shown in FIG. 2, the high voltage battery system 100 of the present invention is mounted on a fuel cell vehicle or a hybrid vehicle that requires a battery system that outputs a high voltage.

고전압 배터리 시스템(100)은 모터에 의해 시동을 걸거나 기타 배터리의 사용이 필요한 경우 차량제어유닛(Vehicle Control Unit, VCU, 120-도면에는 편의상 VCCU로 표기함)에 의해 제어되는 릴레이(110)에 의해 배터리가 작동됨으로써 구현된다.The high voltage battery system 100 is connected to a relay 110 controlled by a vehicle control unit (VCU, 120-drawing shown as VCCU for convenience) when starting by a motor or using other batteries. By the battery is implemented.

고전압 배터리 시스템(100)은 주로 차량의 트렁크 내부나 시트 밑 등에 장착되므로, 릴레이(110)의 작동음이 차량의 탑승자에게 소음으로 인식될 수 있다.Since the high voltage battery system 100 is mainly mounted in the trunk of a vehicle or under a seat, the operation sound of the relay 110 may be recognized as a noise by a passenger of the vehicle.

릴레이(110)의 동작시 단자 연결판이 상하로 움직이면서 'ON/OFF'되는데, 단자 연결판이 붙었다 떨어졌다 하는 동작음을 내게 된다.The terminal connecting plate is moved up and down during the operation of the relay 110 'ON / OFF', the terminal connecting plate is attached and dropped the operation sound.

일반적으로 운전자가 방향 지시등이나 와이퍼 등을 작동할 때도 릴레이의 작동음이 발생하지만, 이 경우 정상 작동을 판단하는 기준이 되므로 소음으로 인식하지 않게 된다. In general, when a driver operates a turn signal or a wiper, the operation sound of the relay is generated. However, in this case, it is not recognized as a noise because it serves as a standard for determining normal operation.

따라서 운전자나 탑승객이 고전압 배터리 시스템(100)의 릴레이(110) 작동음을 정상 동작음으로 인식할 수 있도록 릴레이(110)의 동작시 운전석 클러스터에 지시등(indicator, 130, 도 3에 영문으로 표기하였음)이나 차임벨 등으로 릴레이(110)의 동작을 알려주는 것이 바람직하다.Therefore, an indicator (130) is indicated in English in the driver's seat cluster during operation of the relay 110 so that a driver or a passenger may recognize the operation of the relay 110 of the high voltage battery system 100 as a normal operating sound. It is preferable to inform the operation of the relay 110 through the chime or).

도 3에 도시된 바와 같이, 운전자나 탑승객이 릴레이(110)의 작동음을 정상 동작음으로 인식하도록 하기 위해 먼저 키(key)가 삽입되어 시동 상태인지를 차량 제어유닛(120)이 판단(S100)한다. 키 시동 상태이면 차량제어유닛(120)에서 릴레이(110)를 'ON' 시키기 위한 명령을 작성(S200)한다.As shown in FIG. 3, the vehicle control unit 120 determines whether a key is inserted and started so that a driver or a passenger recognizes the operation sound of the relay 110 as a normal operation sound (S100). )do. If the key is in the start state, the vehicle control unit 120 prepares a command for 'ON' the relay 110 (S200).

차량제어유닛(120)에서 릴레이(110) 'ON' 신호를 작성했으면 운전자에게 지시등(130)이나 차임벨을 통해 이를 알리게 된다(S300). 릴레이(110)가 작동됨을 운전자에게 미리 알린 후 차량제어유닛(120)이 릴레이(110)를 'ON' 시키므로(S400), 릴레이(110)의 작동음이 발생하더라도 운전자나 탑승객은 이를 정상 작동음으로 인식하게 된다. 릴레이(110)의 작동 후 운전자에게 알리기 위해 작동했던 지시등(130)이나 차임벨의 작동을 해제한다(S500).When the relay control unit 110 generates the 'ON' signal in the vehicle control unit 120, the driver is notified through the indicator light 130 or the chime bell (S300). After notifying the driver in advance that the relay 110 is activated, the vehicle control unit 120 turns the relay 110 on (S400), even though the operation sound of the relay 110 occurs, the driver or the passenger hears the normal operation sound. Will be recognized. After the operation of the relay 110 releases the operation of the indicator light 130 or the chime that was operated to inform the driver (S500).

키 시동 상태가 아니면 이러한 단계를 거치지 않고 대기 상태를 유지한다.If the key is not in the startup state, the standby state is maintained without going through these steps.

상기 S200의 단계에서 차량제어유닛(120)이 릴레이(110) 'ON' 명령을 작성하지 않았으면 차량제어유닛(120)이 릴레이(110) 'OFF' 명령을 작성하는지 판단한다(S210).If the vehicle control unit 120 does not write the relay 110 'ON' command in step S200, it is determined whether the vehicle control unit 120 writes the relay 110 'OFF' command (S210).

차량제어유닛(120)이 릴레이(110) 'OFF' 신호를 작성했으면 운전자에게 지시등(130)이나 차임벨을 통해 이를 알리게 된다(S230). 운전자에게 알린 후 차량제어유닛(120)이 릴레이(110)를 'OFF' 시키므로(S250), 릴레이(110)의 작동음이 발생하더라도 운전자나 탑승객은 이를 정상 작동음으로 인식하게 된다. 릴레이(110)의 오프 후 운전자에게 알리기 위해 작동했던 지시등(130)이나 차임벨의 작동을 해제한다(S500).When the vehicle control unit 120 writes the relay 110 'OFF' signal, the vehicle control unit 120 notifies the driver through the indicator light 130 or the chime bell (S230). After notifying the driver, the vehicle control unit 120 turns the relay 110 'OFF' (S250), even though the operation sound of the relay 110 is generated, the driver or the passenger recognizes the normal operation sound. After the relay 110 is turned off, the operation of the indicator light 130 or the chime which is operated to notify the driver is released (S500).

이러한 방법에 의해 고전압 배터리 시스템(100)의 작동 상태를 운전자나 탑승자에게 알릴 수 있으며, 이를 구현하기 위해 운전석의 클러스터에 별도의 지시등 을 추가하거나 차임벨 기구를 추가하는 것이 바람직하다.In this way, it is possible to inform the driver or the passenger of the operating state of the high voltage battery system 100, and to implement this, it is preferable to add a separate indicator light or a chime mechanism to the cluster of the driver's seat.

이러한 방법에 의해 별도의 차음재 없이도 릴레이의 작동음을 운전자나 탑승객이 소음으로 인식하지 않도록 할 수 있다.In this way, it is possible to prevent the driver or passengers from recognizing the operation sound of the relay as noise without any sound insulation.

한편, 본 발명은 상기한 실시 예에 한정되지 않으며, 특허청구범위에서 청구된 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.On the other hand, the present invention is not limited to the above-described embodiment, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention as claimed in the claims. Of course, such changes are intended to fall within the scope of the appended claims.

이상 설명한 바와 같이, 본 발명의 일 실시예에 따른 차량용 고전압 배터리 릴레이의 작동 상태 알림 방법은 릴레이의 작동음을 정상적인 동작음으로 인식하도록 함으로써 릴레이의 작동음을 차폐하기 위한 차음재를 사용하지 않아도 되므로 무게 감소 및 원가 절감의 효과가 있다. 따라서 고가의 저소음 릴레이의 차량 적용을 줄일 수 있다.As described above, the operation state notification method of the high-voltage battery relay for a vehicle according to an embodiment of the present invention does not need to use the sound insulation material for shielding the operation sound of the relay by allowing the operation sound of the relay to be recognized as normal operation sound. It can reduce costs and reduce costs. Therefore, it is possible to reduce the vehicle application of expensive low noise relay.

또한 작동 상황을 운전자 및 탑승자에게 알려주어 고전압 배터리의 동작 상태를 판단할 수 있는 장점이 있다.In addition, there is an advantage that can determine the operating state of the high-voltage battery by informing the driver and the driver of the operation.
