The present invention relates to technology for maximizing effect of improving fuel efficiency by determining an optimum operating point of an engine and a motor in consideration of a battery SOC and an engine load. According to the present invention, disclosed is a method for controlling minimum energy consumption driving of a vehicle, which calculates driving energy by summing fuel consumption energy calculated by reflecting a fuel consumption factor according to an optimum engine operation region and battery consumption energy calculated by reflecting a battery consumption factor according to the battery SOC, and drives the engine and the motor at the optimum operating point that consumes the minimum driving energy among the calculated driving energy consumption, thereby maximizing fuel economy improvement.

    본 발명은 배터리 SOC와 엔진 부하를 고려하여 엔진과 모터의 최적 운전점을 결정함으로써, 연비 개선 효과를 극대화하는 기술에 관한 것으로, 본 발명에서는, 최적엔진운전영역에 따른 연료소비팩터가 반영되어 산출된 연료소비에너지와, 배터리 SOC에 따른 배터리소비팩터가 반영되어 산출된 배터리소비에너지를 합산하여 운전소비에너지를 산출하고, 산출된 운전소비에너지 중에서 최소의 운전소비에너지를 소비하는 최적 운전점으로 엔진과 모터를 구동함으로써, 연비 향상을 극대화하는 것을 특징으로 하는 차량의 최소 소비에너지 운전 제어방법이 소개된다.
