COOLING WATER CONTROL APPARATUS

摘要

A cooling water control apparatus has a setting device which sets a target heat amount line such that a condition where a transferred heat amount which is transferred to a heater core is equal to a required heat amount which is required by the heater core is satisfied at a desired time point at which the transferred heat amount starts to be actually used, the target heat amount line representing a successive target value of the transferred heat amount during a period until the desired time point; and a first controlling device which makes a cooling water circulate in a first pipe, stops the circulation of the cooling water in a second pipe and adjusts an output of an engine such that the transferred heat amount follows the target heat amount line.

主权项

1. A cooling water control apparatus which controls a cooling apparatus,
the cooling apparatus having: (i) a first pipe in which a cooling water circulates between an exhaust heat recovery equipment and a heater core while bypassing the engine; and (ii) a second pipe in which the cooling water circulates between the engine and the heater core, the cooling water control apparatus having a controller; the controller being configured to set a target heat amount line such that a condition where a transferred heat amount which is transferred to the heater core is equal to a required heat amount which is required by the heater core is satisfied at a desired time point at which the transferred heat amount starts to be actually used, the target heat amount line representing a successive target value of the transferred heat amount during a period until the desired time point; and the controller being configured to (i-1) make the cooling water circulate in the first pipe, (i-2) stop the circulation of the cooling water in the second pipe and (ii) adjust an output of the engine such that the transferred heat amount follows the target heat amount line.
