COOLING SYSTEM CONTROL DEVICE

摘要

The objective of the present invention is to reduce the impact of condensed water on an EGR device. This device (100) controls a cooling system equipped with an adjustment means capable of adjusting the amount of cooling water circulating in a first flow path, which includes an engine cooling flow path, an EGR cooling flow path, and a radiator flow path, and a second flow path, which includes the engine cooling flow path, the EGR cooling flow path, and a bypass flow path, but does not include the radiator flow path. This control device is equipped with: an identification means that identifies the temperature of the cooling water; a restriction means that restricts the circulation of the cooling water when the internal combustion engine starts up; and a control means that preferentially circulates the cooling water in the second flow path by controlling the adjustment means on the basis of the identified temperature during the period when circulation of the cooling water is restricted.
