Abstract

본 발명은 자동차의 EHC에 공급되는 전력 에너지를 조절하도록 하기에 적합한 EHC를 제어하는 장치 및 그 방법에 관한 것으로, 종래에는 적정량의 유체흐름이 존재하지 않으면 EHC에서 발생한 열량이 LOC로 전달이 이루어지지 않기 때문에 정화성능의 향상을 기대할 수 없었으나, 본 발명에서는 이차공기를 공급하므로 EHC(18)에서 발생한 열량을 충분히 LOC(26)에 전달할 수 있으므로 촉매 활성화 시간이 앞당겨지며, 정화 효율이 향상되어 상기 결점을 개선시킬 수 있는 것이다.The present invention relates to an apparatus and method for controlling an EHC suitable for controlling the power energy supplied to the EHC of a vehicle. In the related art, if an appropriate amount of fluid flow does not exist, heat generated from the EHC is not transferred to the LOC. However, the improvement of the purification performance could not be expected. However, in the present invention, since the secondary air is supplied, the amount of heat generated from the EHC 18 can be sufficiently transmitted to the LOC 26, thereby improving the catalyst activation time and improving the purification efficiency. It can improve the shortcomings.
