Zusammenfassung:	The present invention relates to an apparatus and method for controlling a heater of a fuel filter for a vehicle so as to newly improve an on/off control method of a relay for heater power for a heater operation of a diesel fuel filter. In other words, the present invention detects a fuel temperature by use of a fuel temperature detection sensor installed in an engine, and if the fuel temperature is lower than or equal to a reference temperature, turns on the relay for heater power in an engine control unit (ECU). However, if the fuel temperature is greater than or equal to the reference temperature, if heater operating time is greater than or equal to a predetermined time, or if a battery voltage is less than or equal to a predetermined voltage, the present invention turns off the relay for heater power, thus implementing an on/off control of a heater. 본 발명은 디젤 연료필터의 히터 작동을 위한 히터 전원용 릴레이의 온/오프 제어 방식을 새롭게 개선시킨 자동차용 연료필터의 히터 제어 장치 및 방법에 관한 것이다. 즉, 본 발명은 엔진에 장착되는 연료온도 감지센서를 이용하여 연료온도를 감지한 후, 연료온도가 기준온도 이하이면 엔진 ECU에서 히터 전원용 릴레이를 온시키고, 연료온도가 기준온도 이상이거나 히터 작동시간이 일정시간 이상이거나 배터리 전압이 일정전압 이하이면 엔진 ECU에서 히터 전원용 릴레이를 오프시킬 수 있도록 함으로써, 정밀한 히터 온/오프 제어를 실현할 수 있는 자동차용 연료필터의 히터 제어 장치 및 방법을 제공하고자 한 것이다.
