Abstract

An electronic control device is applied to an internal combustion engine including an engine driving pump, circulates lubricant by use of a driving force of the internal combustion engine, and reduces that driving load of the pump which works on the internal combustion engine, by executing a low-pressure control to limit a circulation amount of the lubricant when demand for the lubricant is small. Further, when a predetermined automatic stop condition is established, an engine operation is stopped automatically, and when a predetermined restart condition is established during the automatic stop, the internal combustion engine is restarted. Further, the execution of the low-pressure control is prohibited at the time of starting the internal combustion engine along with an operation of an ignition switch, but the execution of the low-pressure control is allowed at the time of restarting the internal combustion engine.
