Abstract
A method of controlling a cooling system for a hybrid electric vehicle can include measuring an outside air temperature, determining whether the measured outside air temperature is within a preset low-temperature environment temperature range, determining, in a case where a determination is made that the outside air temperature is within the low-temperature environment temperature range, whether a vehicle state corresponds to a preset heating mode, detecting, in a case where a determination is made that the vehicle state does not correspond to the heating mode, a coolant temperature, and controlling, in a case where a determination is made that the coolant temperature detected by a coolant temperature measurement unit is within a preset target temperature range, opening and closing of a control valve by the controller to selectively perform a coolant flow stop control in a low-temperature environment.
