Cooling system for a vehicle

A cooling system for a vehicle, the cooling system comprising:

• a cooling apparatus including a radiator and a first water pump connected by a coolant line and circulating a coolant to the coolant line;
• a battery module provided on a battery coolant line selectively connected to the coolant line through a first valve;
• a first chiller provided on the battery coolant line between the first valve and the battery module, and connected to a refrigerant line of an air-conditioning apparatus, the first chiller configured to heat-exchange the selective inflowed coolant with the refrigerant supplied from the air-conditioning apparatus to adjust a temperature of the coolant;
• an automatic driving controller connected to the coolant line so that the coolant is circulated inside;
• a first branched line selectively connecting the battery coolant line through the operation of the first valve so that the first chiller and the battery module form an independent closed and sealed circuit through the battery coolant line;
• and
• a second branched line selectively dividing the coolant line and the battery coolant line,
• wherein the battery module or the automatic driving controller is cooled selectively by at least one cooling mode,
• wherein the automatic driving controller is provided on a coolant connection line connected to the coolant line through a second valve, and
• wherein at least one cooling mode includes:
• a first cooling mode cooling both the battery module and the automatic driving controller by using the coolant cooled in the radiator;
• a second cooling mode cooling the automatic driving controller by using the coolant cooled in the radiator and cooling the battery module by using the coolant cooled in the first chiller;
• and
• a third cooling mode cooling the battery module by using the coolant cooled in the radiator and independently cooling the automatic driving controller.
