A method for controlling a powertrain of a hybrid vehicle includes the following steps performed by a hybrid controller: determining whether an ambient air temperature is lower than a predetermined temperature; driving a motor and operating a heating disc of an electrically heated catalytic converter disposed in an exhaust pipe of an internal combustion engine during a predetermined operating time when an ambient air temperature is lower than a predetermined temperature; supplying ambient air to the heating disc; and varying a flow rate of the ambient air supplied to the heating disc in response to a temperature change of the heating disc.
