The present invention relates to a variable control method for an engine starting point when an engine clutch of a hybrid vehicle is connected, which is capable of variably controlling an engine starting point according to a load applied to an engine when an engine clutch is connected. That is, an objective of the present invention is to determine an engine load in consideration with an inclination of a road, an atmospheric pressure, etc., variably control the engine starting point in an engine speed controlling section according to a degree of the load such that a battery is charged according to the HSG power generation, thereby preventing generation of engine vibrations and consequent disturbance to a passenger while controlling the connection of the engine clutch.

    본 발명은 하이브리드 차량의 엔진 클러치 접합시 엔진에 걸리는 부하에 따라 엔진 운전점을 가변 제어할 수 있도록 한 하이브리드 차량의 엔진 클러치 접합시 엔진 운전점 가변 제어 방법에 관한 것이다. 즉, 본 발명은 도로의 기울기, 대기압 등을 고려한 엔진 부하를 판단하고, 부하 정도에 따라 엔진 속도제어구간에서 엔진 운전점을 가변 제어하여 HSG 발전에 따른 배터리 충전이 이루어지도록 함으로써, 엔진클러치 접합 제어 중 엔진 떨림 및 그에 따른 승객 이질감 발생을 방지할 수 있도록 한 하이브리드 차량의 엔진 클러치 접합시 엔진 운전점 가변 제어 방법을 제공하고자 한 것이다.
