Abstract
A hybrid vehicle may run with only the power from a motor MG, while an engine is at a stop. In this state, the control procedure drives a motor MGto rotate a crankshaft at an idling engine speed for a predetermined time period, when at least one of an observed oil temperature in a sump, an observed temperature of the motor MG, an observed temperature of the motor MG, an observed revolving speed of the motor MG, and an observed revolving speed of the motor MGis not less than a corresponding preset value. Rotation of the crankshaft at the idling engine speed results in driving an oil pump to feed a supply of lubricating oil to mechanical part of the power output apparatus including a power distribution integration mechanism.
