Abstract:
A cooling control system for an engine, in which a circulating passage of a cooling medium is formed between a fluid conduit formed in the engine and a fluid conduit formed in a heat exchanger, and heat generated in the engine is dissipated with the heat exchanger by circulating the cooling medium in the circulating passage, comprising:a flow control mechanism controlling the flow of the cooling medium in the circulating passage between the engine and the heat exchanger in accordance with the degree of valve opening;an information extracting mechanism extracting at least load information in respect of the engine and temperature information of the cooling medium; anda control unit finding a target setting temperature of the cooling medium on the basis of the load information, and finding a temperature deviation of the temperature information of the cooling medium from the target setting temperature, and generating a control signal for an actuator of said flow control mechanism on the basis of the relationship between the temperature deviation and a changing velocity of the temperature deviation.
