Abstract: A thermal management system for a vehicle includes an engine cooling circuit that causes a heat medium to circulate through an engine, and an engine radiator that exchanges heat between the heat medium in the engine cooling circuit and outside air. The thermal management system for a vehicle further includes a switching device that switches between an independent mode in which the heat medium circulates respectively independently through a cooler cooling circuit and the engine cooling circuit, and a communication mode in which the cooler cooling circuit and the engine cooling circuit communicate with each other to cause the heat medium to flow between a chiller and the engine radiator; and a controller that controls an operation of the switching device to switch to the communication mode when a temperature of the heat medium in the engine cooling circuit is lower than a first heat-medium temperature.
