하이브리드 제어기를 사용하여 클러치에 의해 결합된 엔진과 이머신을 갖는 하이브리드 차량을 동작시키는 시스템과 방법이 제공된다. 방법은, 엔진의 유휴 연료 소비율을 결정하고, 하이브리드 차량에 대한 하이브리드 효율성 지수를 결정하며, 엔진이 상기 클러치를 사용하여 차량 트랜스미션으로부터 결합이 해제되는 동작 상황에 대한 예상 에너지 저장률 증가를 결정하고, 동작 상황에서 엔진의 예상 연료 소비율 감소를 결정하기 위해 예상 에너지 저장률 증가와 하이브리드 효율성 지수를 곱하며, 예상 연료 소비율 감소가 유휴 연료 소비율보다 클 때에 클러치를 이용하여 차량 트랜스미션으로부터 엔진을 연결 해제한다.

    A system and method for operating a hybrid vehicle having an engine and an eMachine coupled by a clutch using a hybrid controller is presented. The method determines an idle fuel rate of the engine, determines a hybrid efficiency index for the hybrid vehicle, determines an expected energy storage rate increase for an operating condition where the engine is decoupled from a vehicle transmission using said clutch, multiplies the expected energy storage rate increase by the hybrid efficiency index to determine an expected fuel rate reduction of the engine in the operating condition; and decouples the engine from the vehicle transmission using the clutch if the expected fuel rate reduction is greater than the idle fuel rate.
