A hybrid vehicle may run with only the power from a motor MG 2 , while an engine is at a stop. In this state, the control procedure drives a motor MG 1 to 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 1 , an observed temperature of the motor MG 2 , an observed revolving speed of the motor MG 1 , and an observed revolving speed of the motor MG 2 is 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.
