Abstract
The engine driving condition is separated into regions A, B and C. The region A is a region indicative of a high load condition. The region B is a region indicative of a low load condition. The region C is region indicative of an idle condition. Control objective temperatures in the respective driving conditions are set to 80, 110 and 95 degrees centigrade for the regions A, B and C, respectively. This enables control of cooling water temperature within the engine to be provided in a manner more adapted for the respective engine driving conditions.
