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.

Method for controlling of cooling system for HEV vehicle

A method for controlling a vehicle cooling system is provided. The system includes an engine, an EGR cooler, an oil cooler, a heater, a radiator, and a controller. The engine, the EGR cooler, the oil cooler, the heater, and the radiator are respectively connected through a coolant line and coolant circulates through the engine, the EGR cooler, the oil cooler, the heater, and the radiator by operation of a water pump. The controller receives the coolant from the engine and operates a control valve that is connected with the oil cooler, the heater, and the radiator. The method includes sensing driving conditions and operating the control valve when a warm mode is required to increase the temperature within the vehicle based on the sensed driving conditions. The control valve is operated based on first to third modes depending on a coolant temperature.

The controller receives the coolant from the engine and operates a control valve connected with the oil cooler, the heater, and the radiator. The method includes sensing driving conditions and operating the control valve when a warm mode is required to rapidly warm up the engine based on the sensed driving conditions. The control valve is operated based on modes that are controlled depending on a coolant temperature, and among modes, one is iteratively performed.
