Abstract
A flow rate ratio of a radiator flow rate to a bypass flow rate is determined from pump water temperature, bypass water temperature and radiator water temperature. The relation between the flow rate ratio and a valve opening degree of a flow control valve is predetermined as a map. The valve opening degree is determined from the flow rate ratio and the map. Accordingly, the cooling water temperature at an inlet of a pump is accurately controlled without detecting the flow rate of the cooling water.
