COOLING WATER CONTROL DEVICE

摘要

A cooling water control device (30) equipped with: a setting means (31) that sets a target heat amount line defining successive target values for the amount of heat supplied for a period until a desired point in time arrives, such that a state in which the amount of heat supplied to a heater core (12) and the amount of heat required by the heater core match is achieved at a desired point in time at which the usage of the supplied amount of heat actually begins; and a first control means (33) that circulates cooling water in a first passage and stops the circulation of cooling water in a second passage, and that adjusts the output of an internal combustion engine (20) such that the supplied amount of heat follows the target heat amount line.
