The present invention provides a generation control method for a series type-hybrid electric vehicle, which controls a torque command of a generator to be slower than a dynamic characteristic of an engine by applying an artificial dead time and a primary delay factor to a torque command value of the generator with a very rapid dynamic characteristic, thereby improving stability of dynamic movement of the engine and the generator. According to the present invention, the generation control method for a series type-hybrid electric vehicle applies a dynamic characteristic according to a math formula (wherein, T_gen indicates the torque of the generator, _d indicates the dead time, _m indicates a time constant, s indicates a laplace operator, T^* indicates a target torque determined by an optimal operation line of the engine with respect to a target generated power (P^*) determined a hybrid controller (HCU) formed by the dead time) and the primary delay factor to the torque command of the generator.

    본 발명은 동특성이 매우 빠른 발전기쪽의 토크 명령값에 인위적인 불감시간과 1차 지연성분을 부여하여 발전기의 토크 명령을 엔진의 동특성보다 느리게 제어하여 엔진과 발전기의 동적 거동의 안정성을 향상시킨 직렬형 하이브리드 전기구동차량의 발전제어방법을 제공한다 본 발명의 직렬형 하이브리드 전기구동차량의 발전제어방법은 발전기의 토크 명령에 대하여 불감시간과 1차지연 성분으로 이루어지는 수학식(여기에서, T은 발전기의 토크를 나타내고, τ는 불감시간을 나타내고, τ은 시정수(Time Constant)를 나타내고, s는 라프라스 연산자를 나타내고, T는 하이브리드제어기(HCU)에서 결정된 목표 발전 파워(P)에 대한 엔진의 최적운전곡선(Optimal Operation Line)에 의해 결정된 목표 토크를 나타냄)와 같은 동특성을 부여하도록 이루어진다.
