Abstract
A cooling systemincludes an electric oil pump, an outside air temperature sensor, an oil temperature sensor, and a controller. The controllerpermits the actuation of the electric oil pumpin one of a first case where an oil temperature To is equal to or greater than a first threshold (A) and where an outside air temperature Ta is equal to or greater than a second threshold (B), a second case where the outside air temperature Ta is less than the second threshold (B) and where the oil temperature To is equal to or greater than a third threshold (C) higher than the first threshold (A), and a third case where the oil temperature To is less than the first threshold (A) and where the outside air temperature Ta is equal to or greater than a fourth threshold (D) higher than the second threshold (B).
