차량의 콘트롤러 제어방법Controller control method of vehicle

본 발명은 차량의 콘트롤러 제어방법에 관한 것으로, 더 상세하게는 에러코드가 없을 때에는 콘트롤러를 오프시킴으로써 콘트롤러의 오동작이나 충격이 가해지는 것을 방지하도록 하는 차량의 콘트롤러 제어방법에 관한 것이다.The present invention relates to a controller control method of a vehicle, and more particularly, to a controller control method of a vehicle to prevent a malfunction or an impact of a controller by turning off the controller when there is no error code.

차량의 이씨유(ECU)들은 각 시스템에 에러가 발생하면 이에 상응하는 조치를 취함과 동시에 에러내용을 콘트롤러내에 저장한다. 도1은 이러한 콘트롤러에 전원을 공급하기 위한 구조를 보인 도면으로서, 이를 참조하면, 각 부품의 작동을 제어하는 콘트롤러(14)에는 배터리(11)가 접속되는데, 이들사이에는 전압조정기(13)가 설치된다. 그리고 전압조정기(13)와 콘트롤러(14)사에는 시동스위치(12)가 병렬로 접속됨으로써 시동시위치(12)가 오프되어도 콘트롤러(14)에 상시 전원이 공급되도록 하여 에러코드를 저장하도록 한다.The ECUs of the vehicle take the corresponding action when an error occurs in each system and store the error contents in the controller. 1 is a diagram showing a structure for supplying power to such a controller. Referring to this, a battery 11 is connected to a controller 14 for controlling the operation of each component, and a voltage regulator 13 is connected between them. Is installed. In addition, the starter 12 is connected to the voltage regulator 13 and the controller 14 in parallel so that the power supply is always supplied to the controller 14 even when the starting position 12 is turned off, thereby storing an error code.

그러나 종래에는 에러코드를 기억하기 위하여 에러코드의 존재 유무에 상관없이 항시 콘트롤러를 온상태로 유지시키기 때문에 암전류(Dark Curret)가 발생되는 문제가 있었다. 또한 엔진정지중에 외부의 강한 전자파에 의한 충격이 가해질 수 있으며, 이로 인한 콘트롤러의 오작동이 염려되는 문제가 있었다.However, in the related art, since a controller is always kept on regardless of the presence or absence of an error code in order to store an error code, a dark current (Dark Curret) occurs. In addition, the impact of the external strong electromagnetic waves may be applied during the engine stop, there was a problem that the malfunction of the controller due to this.

따라서 본 발명은 상기한 문제를 해결하기 위한 것으로, 본 발명의 목적은 에러코드가 없을 경우에는 콘트롤러를 오프시켜 불필요한 암전류의 발생을 억제하고 외부 전자파에 의한 충격과 오동작을 위험을 줄일 수 있는 차량의 콘트롤러 제어방법을 제공하는 것이다.Accordingly, an object of the present invention is to solve the above problem, and an object of the present invention is to turn off the controller in the absence of an error code to suppress the occurrence of unnecessary dark current and reduce the risk of shock and malfunction caused by external electromagnetic waves. It is to provide a controller control method.

It is a method characterized by.

이하에서는 첨부도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하겠다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

도1은 콘트롤러에 전원을 인가하기 위한 일반적인 구조를 보인 도면이다. 이에 도시한 바와 같이, 차량의 작동을 제어하는 콘트롤러(14)에는 배터리(11)가 접속되는데, 이들사이에는 전압조정기(13)가 설치되어 공급되는 전압을 적절히 조정한다. 전압조정기(13)와 콘트롤러(14)사에는 시동스위치(12)가 병렬로 접속됨으로써 시동시위치가 오프되어도 콘트롤러(14)에 전원이 공급되도록 하여 에러코드를 저장하도록 한다.1 is a view showing a general structure for applying power to the controller. As shown in the figure, a battery 11 is connected to the controller 14 for controlling the operation of the vehicle, and a voltage regulator 13 is installed between them to appropriately adjust the voltage supplied. The starter 12 is connected in parallel to the voltage regulator 13 and the controller 14 so that power is supplied to the controller 14 even when the starting position is turned off, thereby storing an error code.

본 발명에 따른 콘트롤러 제어방법은 이와 같은 구성된 콘트롤러(14)에 에러코드가 없을때 전원을 차단함으로써 암전류(Dark Current)의 발생과 외부 전자기파에 의한 충격과 오동작을 최대한 억제하는 것이다. 이를 도2에 도시된 순서도를 참조하여 설명하겠다. 먼저 시동스위치(12)가 오프인가를 판단하는 단계(S101)가 수행된다. 이 S101에서 시동스위치(12)가 오프라고 판단하면 콘트롤러(14)에 에러코드가 존재하는 가를 판단하는 단계(S102)가 수행된다. 단계 S102에서 에러코드가 없다고 판단하면 콘트롤러(14)로 오프시키기 위한 단계(S103)가 수행되고, 에러코드가 있다면 전압조정기(13)의 상태를 유지시키는 단계(s104)가 수행된다. 단계 S103에서는 콘트롤러(14)와 배터리(11)사이에 설치된 전압조정기(13)를 오프시킴으로써 배터리(11)의 전원이 콘트롤러(14)로 공급되는 것을 차단하여 콘트롤러(14)는 오프시킨다.The controller control method according to the present invention is to suppress the generation of dark current (Dark Current) and the impact and malfunction caused by external electromagnetic waves to the maximum by shutting off the power when there is no error code in the controller 14 configured as described above. This will be described with reference to the flowchart shown in FIG. 2. First, it is determined whether the start switch 12 is off (S101). If it is determined in step S101 that the start switch 12 is off, a step S102 of determining whether an error code exists in the controller 14 is performed. If it is determined in step S102 that there is no error code, step S103 for turning off the controller 14 is performed, and if there is an error code, step S104 of maintaining the state of the voltage regulator 13 is performed. In step S103, by turning off the voltage regulator 13 provided between the controller 14 and the battery 11, the controller 14 is turned off by blocking the power supply of the battery 11 from being supplied to the controller 14.

다시 설명하면, 운전자가 시동스위치(12)를 오프시키면 콘트롤러(14)에 에러코드가 있는지를 판단하여 에러코드가 없으면 전압조정기(13)를 오프시켜 콘트롤러(14)을 오프시키고, 에러코드가 있으면 배터리(11)의 전원이 콘트롤러(14)로 공급되도록 하여 콘트롤러(14)가 작동시켜 에러코드를 기억하도록 하는 것이다.In other words, when the driver turns off the start switch 12, the controller 14 determines whether there is an error code. If there is no error code, the driver 14 turns off the controller 14 by turning off the voltage regulator 13, The power of the battery 11 is supplied to the controller 14 so that the controller 14 operates to store the error code.

이상에서 상세하게 설명한 바와 같이, 본 발명에 따른 차량의 콘트롤러 제어방법은 에러코드가 없는 경우에 콘트롤러를 오프시키기 때문에 콘트롤러가 배터리의 전원으로 동작하는 것을 최대로 억제함으로써 암전류의 발생과 엔진이 오프되었을때 외부 전자기파에 의한 충격 및 이로 인한 오동작을 최대로 억제할 수 있는 이점이 있다.As described in detail above, since the controller control method of the vehicle according to the present invention turns off the controller in the absence of an error code, the generation of dark current and the engine may be turned off by maximally suppressing the controller operating from battery power. When the shock caused by the external electromagnetic waves and the resulting malfunction there is an advantage that can be suppressed to the maximum.
