The invention discloses a vehicle cooling system and a vehicle cooling method, and relates to the technical field of vehicle thermal management. The cooling system of the vehicle comprises a power battery cooling loop, a motor controller cooling loop, a compressor loop and a multi-way valve, when the multi-way valve is in a first communication state, the power battery cooling loop cools a power battery through the compressor loop, and the motor controller cooling loop cools a motor controller through a radiator; when the multi-way valve is in a second communication state, the power battery and the motor controller are cooled through the cooling medium output by the radiator; and when the multi-way valve is in the third communication state, the power battery cooling loop cools the power battery through the compressor loop, and the motor controller cooling loop cools the motor controller through the radiator and the compressor loop. The technical problems that a cooling system is complex in structure and high in cooling cost are solved.
