Abstract
A control device is applied to an engine cooling system having a flow volume adjustment valve and a heat recovery unit. The control device includes a first learning unit which actuates a valve body to move to a valve-opening side by a predetermined amount at a time while a channel in the flow volume adjustment valve to the heat recovery unit is closed and learns a valve-closing position according to a coolant liquid that flows a circulation path and a second learning unit which actuates, after the valve-closing position is learned by the first learning unit, the valve body to move to the valve-opening side by a predetermined amount at a time within a range of a learned value while the channel is closed and determines to maintain the learned value and ends learning of the valve-closing position when the coolant liquid is not flowing the circulation path.
