상기 절연저항 측정단계(S100)에서 절연저항의 측정시에는 10초 이상 절연저항 값을 측정하도록 하고, 측정한 절연저항 값이 10초 이상 측정한 것인지 아닌지를 확인하는 측정시간 확인단계(S150)를 더 포함하여 측정시간 확인단계를 통해 10초 이상 측정된 것으로 확인된 경우에만 상기 비교단계를 거치도록 한다.When the insulation resistance is measured in the insulation resistance measurement step (S100), the insulation resistance value is measured for 10 seconds or more, and the measurement time checking step (S150) for confirming whether the measured insulation resistance value is measured for 10 seconds or more. In addition, the comparison step is to be performed only when it is confirmed that the measurement time is measured over 10 seconds.
상기 부품 이상 확인단계(S300)에서는 절연저항 값이 허용치 이하인 경우에 정션박스에 연결된 고전압 부품에 이상이 발생된 것인지를 확인하기 위한 단계로서, 각 고전압 부품에 연결된 정션박스의 각 스위치를 순서대로 오프하면서 절연저항 값을 측정하게 되고, 어느 하나의 고전압 부품이 오프된 상태에서 절연저항 값이 정상으로 복귀하게 되면, 그 해당 스위치 오프된 고전압 부품에 이상이 발생된 것임을 확인할 수 있게 되는 것이다.The component abnormality checking step (S300) is a step for checking whether an abnormality occurs in the high voltage component connected to the junction box when the insulation resistance value is less than the allowable value, and sequentially turns off each switch of the junction box connected to each high voltage component.

It may include a driving step (S430).
상기 부품판단단계에서 주행에 영향을 주는 부품은 인버터, 모터, 배터리 등이고, 주행에 영향을 주지 않는 부품은 LDC, PTC, A/C, OBC이다. 이때 LDC 이상으로 확인된 경우에는 토크 및 속도에 제한이 있도록 제한운행하도록 하고, PTC, A/C, OBC 이상으로 확인된 경우에는 정상운행하도록 한다.In the component determination step, components that affect driving are inverters, motors, batteries, and the like, and components that do not affect driving are LDC, PTC, A / C, and OBC. At this time, if it is confirmed that the LDC or higher, limit the operation to limit the torque and speed, and if it is confirmed that the PTC, A / C, OBC or higher, the normal operation.

도 1은 본 발명의 일 실시예에 따른 절연파괴 검출에 따른 주행제어방법을 나타낸 순서도로서, 차량의 키 온(Key on) 후 샷시 그라운드와 고전압 배터리의 양극과 음극을 교대로 연결하여 절연저항 값을 측정하는 절연저항 측정단계(S100)을 수행하고, 측정한 절연저항 값이 10초 이상 측정한 절연저항 값인지 아닌지를 판단하는 측정시간 확인단계(S150)를 수행하며, 10초 이상 측정한 것으로 확인된 경우 그 측정된 절연저항 값과 이미 설정하여 놓은 허용치를 비교하여 이상 여부를 판단하게 된다(S200).1 is a flowchart illustrating a driving control method according to an insulation breakdown detection according to an embodiment of the present invention. After the key on of a vehicle, a shunt ground and an anode and a cathode of a high voltage battery are alternately connected, To perform the insulation resistance measurement step (S100) to measure the measurement, and to determine whether the measured insulation resistance value is the insulation resistance value measured for 10 seconds or more to perform a measurement time check step (S150), and to measure for 10 seconds or more If confirmed, it is determined whether the abnormality by comparing the measured insulation resistance value and the allowable value already set (S200).
측정된 절연저항 값이 허용치 이하인 것으로 판단된 경우, 운전자가 이를 인지하도록 차량의 클러스터에 표시하여 절연저항을 확인하도록 하는 표시단계(S250)를 수행하고, 이 후 각 고전압 부품에 전원공급을 위해 마련된 정션박스의 각 스위치를 순서대로 오프하면서 절연저항 값을 측정하며, 그 측정된 절연저항 값이 정상으로 복귀하게 되면 해당 스위치 오프된 부품에 이상이 발생된 것으로 판단하여 고전압 부품의 이상 여부를 확인하게 된다(S300).If it is determined that the measured insulation resistance value is less than the allowable value, the display step (S250) is performed to display the cluster on the vehicle so as to recognize the driver to check the insulation resistance, and then the power supply to each high voltage component is provided. Turn off each switch in the junction box in order to measure the insulation resistance value.When the measured insulation resistance value returns to normal, it is determined that an error has occurred in the switch-off part. It becomes (S300).
그리고, 이상이 발생된 것으로 확인된 고전압 부품이 주행에 영향을 주는 부품인지를 판단하는 부품판단단계(S410)를 수행하고, 주행에 영향을 주는 부품(인버터, 모터, 배터리)인 것으로 판단된 경우 전원공급을 차단하여 주행불가상태로 제어하는 주행불가단계(S420)를 수행한다.In addition, when performing the component determination step (S410) to determine whether the high-voltage component is confirmed that the abnormality is a part that affects the driving, it is determined that the component (inverter, motor, battery) affecting the driving It performs a driving impossibility step (S420) for controlling the power supply is impossible to cut off the power supply.
이때, 주행에 영향을 주지않는 부품(LDC, PTC, A/C, OBC)인 것으로 판단된 경우에는 주행상태로 제어하게 되는데, LDC에 이상이 발생한 경우에는 토크 및 속도에 제한을 두도록 하여 제한운행하도록 제어하고, PTC, A/C, OBC에 이상이 발생한 경우에는 차량을 운행하여도 엔진장치에 미비하거나 전혀 해를 끼치지 않음에 따라 정상운행하도록 제어하게 된다(S430).At this time, when it is determined that the parts (LDC, PTC, A / C, OBC) does not affect the driving, the driving state is controlled. When an abnormality occurs in the LDC, the torque and the speed are restricted so that the driving is limited. When abnormality occurs in PTC, A / C, and OBC, the vehicle is controlled to operate normally as the engine device is insufficient or does not cause any harm even when the vehicle is driven (S430).
따라서, 절연저항 값이 허용치 이하인 경우에 즉시 전원공급을 차단하지 아니하고, 이상이 발생된 해당 고전압 부품이 주행에 영향을 주는 부품인지를 확인하여 전원의 공급여부를 판단하도록 함으로써 효율적으로 주행할 수 있는 것이다.Therefore, when the insulation resistance value is less than the allowable value, the power supply is not immediately cut off, and the high voltage component having the abnormality is determined to be a part that affects the driving, and the power supply can be judged to determine whether the power is supplied. will be.
