A disclosed powertrain control method for a hybrid vehicle drives a drive motor when the outside air temperature is less than a set temperature, operates a heating disk of an electrothermal catalyst disposed in an exhaust pipe of an internal combustion engine for a set operating time, supplies outside air to the heating disk, and varies the flow rate of outside air supplied to the heating disk. The powertrain control method for a hybrid vehicle can satisfy strict emission regulations by achieving activation of the electrothermal catalyst very quickly and preventing the heating disk of the electrothermal catalyst from overheating.
개시된 하이브리드차량의 파워트레인의 제어방법은, 외기온도가 설정온도 미만일 때, 구동모터을 구동시키고, 내연기관의 배기관에 배치된 전열촉매의 히팅디스크를 설정된 작동시간 동안 작동시키며, 히팅디스크로 외기를 공급하고, 상기 히팅디스크의 온도변화에 따라 상기 히팅디스크로 공급되는 외기의 유량을 가변한다.
