The present invention relates to an apparatus and method for controlling an engine start during refueling of a hybrid vehicle, which block an engine start or release the blocking of the engine start in accordance with the vehicle speed and the open or closed state of the fuel injection port during refueling of a hybrid vehicle. The apparatus for controlling an engine start during refueling of a hybrid vehicle according to the present invention comprises: a refueling state entrance sensor for controlling an engine to stop the engine and block the engine start by sensing whether a vehicle enters into a refueling state in accordance with the open or closed state of the port, a vehicle speed, and brake pedal state (BPS) information input to an electronic control unit (ECU) or a hybrid control unit (HCU); and a refueling state release sensor for controlling the engine to start the engine according to an HEV mode switching and release blocking of the engine start by sensing whether the refueling state is released in accordance with the open or closed state of the port, the vehicle speed, and acceleration pedal state (APS) information input to the ECU or the HCU. In addition, the method for controlling an engine start during refueling of a hybrid vehicle according to the present invention comprises: the steps of determining the open or closed state of the fuel injection port; determining vehicle stop; permitting engine start; blocking engine start; and releasing refueling state.
본 발명은 하이브리드 차량의 주유 중 차량속도 및 연료주입구 개폐상태에 따라 엔진 시동을 차단하거나 차단을 해제하는 제어 장치 및 방법에 관한 것으로, 본 발명에 따른 하이브리드 차량의 주유 중 엔진 시동 제어 장치는 ECU 또는 HCU에 입력되는 연료주입구 개폐상태, 차량속도 및 BPS 정보로부터 차량이 주유 상태에 진입하였는지를 감지하여 엔진을 정지하고 시동을 차단하도록 엔진을 제어하는 주유 상태 진입 감지부; 및 ECU 또는 HCU에 입력되는 연료주입구 개폐상태, 차량속도 및 APS 정보로부터 주유 상태가 해제되었는지를 감지하여 엔진 시동 차단을 해제하고 HEV 모드 전환에 따라 엔진이 시동될 수 있도록 엔진을 제어하는 주유 상태 해제 감지부;를 포함하여 구성된다. 또한, 본 발명에 따른 하이브리드 차량의 주유 중 엔진 시동 제어 방법은 연료주입구 열림 판단 단계, 정차 판단 단계, 엔진 시동 허용 단계, 엔진 시동 차단 단계 및 주유 상태 해제 판단 단계를 포함하여 구성된다.
