Abstract
A cooling control system for an internal combustion engine, which is capable of efficiently driving an electric water pump, thereby improving fuel economy as much as possible while properly performing cooling of supercharged intake air by an intercooler. The engine to which the present invention is applied includes a turbocharger for supercharging intake air and is configured such that electrical power is generated by a generator using the engine as a motive power source, during a decelerating fuel-cut operation in which fuel supply is stopped. The cooling control system of the present invention includes the intercooler of water-cooled type which cools the intake air supercharged by the turbocharger by using coolant circulating through an intake air cooling circuit and an electric pump for circulating the coolant through the intake air cooling circuit, and drives the electric pump during the decelerating fuel-cut operation.
