Abstract: PURPOSE: An engine throttle device for a vehicle is provided to prevent a sudden acceleration caused by malfunction of an ECU(Engine Control Unit) because a rotation state of the throttle valve is controlled with mechanical displacement according to an operation state of an accelerator pedal. CONSTITUTION: An engine throttle device for a vehicle comprises a throttle valve(3), a rotating member(5), rotation-restricting unit(7), an accelerator pedal(9) and a displacement transmission unit(11). The throttle valve is rotated by torque from a motor. The rotating member is connected to a rotary shaft of the throttle valve. The rotation-restricting unit converts the rotating member into a rotatable state or a non-rotatable state by the mechanical displacement. The displacement transmission unit transfers the mechanical displacement of the accelerator pedal to the rotation-restricting unit.

Abstract: 본 발명은 하이브리드 차량에 적용되는 전력제어시스템에 관한 것이다. 본 발명은 메인배터리, 보조배터리를 관리하며 상기 메인배터리의 SOC(State Of Charge) 값을 모니터링하여 출력하는 BMS(Battery Management System); 상기 메인배터리로부터 공급된 전압을 변환하여 상기 보조배터리를 충전하는 LDC(Low Voltage DC-DC Converter); 및 상기 BMS로부터 입력된 메인배터리의 SOC 값이 사전에 정해진 비상값보다 작다고 판단한 경우, 사전에 정해진 엔진구동시간 동안 엔진을 구동하기 위한 LDC사용금지제어명령을 생성하고, 상기 생성된 LDC사용금지제어명령을 수행함과 동시에 내장된 비휘발성메모리에 저장하는 HCU(Hybrid Control Unit);를 포함하는 것을 특징으로 한다. 이에 의해, 본 발명은 방전된 보조배터리의 교체작업 후, IG ON 시점에 일정시간 엔진을 구동함으로써 HCU가 실제 SOC 값을 인지하지 못해 발생할 수 있는 메인배터리의 손상을 사전에 방지할 수 있다.
