차량의 시동시 냉시동 진입여부를 판단하고, 냉시동 진입시 연료전지 스택 냉각수 온도에 따라 목표발열량을 산출하며, 시동 전 정차상태에서 측정된 정차상태 냉각수 온도가 기준온도에 도달할 때까지 소요될 것으로 예상되는 예상시간을 도출하고, 정차상태 냉각수 온도를 측정한 시점부터 냉시동에 진입한 시점까지 소요된 소요시간을 도출하며, 예상시간과 소요시간의 비율에 따라 목표발열량을 보정하여 최종목표발열량을 도출하고, 연료전지 스택의 발열량이 최종목표발열량에 도달하도록 하는 연료전지 차량의 냉시동 제어방법 및 제어시스템이 소개된다.

    A cold start control method and system for fuel cell vehicles determines when the fuel cell vehicle is started, whether the fuel cell vehicle enters a cold start mode. An estimated time estimated to be required until the stopped vehicle coolant temperature, which is measured in a state in which the fuel cell vehicle is stopped before being started, reaches a reference temperature is derived. The required time required from a point in time at which the stopped vehicle coolant temperature is measured to a point in time at which the fuel cell vehicle enters the cold start mode is derived. A target heating value is corrected according to a ration between the estimated time and the required time to derive a final target heating value. The heating value of the fuel cell stack is caused to reach the final target heating value.
