Abstract: PROBLEM TO BE SOLVED: To provide a cooling control device for an internal combustion engine capable of avoiding overheat which damages the internal combustion engine by appropriately suppressing heat generation of the internal combustion engine when cooling power is insufficient.
SOLUTION: An ECU detects the water temperature thw of cooling water (S1), compares the water temperature thw0 Δt seconds before with the present water temperature thw, and determines whether or not Δt=(thw-thw0)/Δt0, (thw+Δt×t) > threshold ts1 (S2), and further determines whether or not water temperature thw > threshold ts2 (S3). In the case of exceeding the threshold ts1, ts2, an engine check lamp is lighted as emergency control (S4), throttle opening is compared with a threshold d (S5, S6), the throttle opening is lowered to the threshold d (S7), and the upper limit of the throttle opening is limited to the threshold d (S8). In addition, an electric W/P and an electric fan are operated to the maximum. With this emergency control (S4-S9), the engine is cooled to avoid overheat.
