PROBLEM TO BE SOLVED: To guarantee lubrication of an engine transmission system part accompanied with a vehicle during electric running that oil is not discharged from a pump driven by an engine due to engine stop.SOLUTION: Lubrication inability of a rotation part of an engine transmission system accompanied with an EV-running vehicle can be prevented, as the rotation part is lubricated by oil from an oil pump by starting an engine (S22) when a lubrication control necessity continuation time t reaches a lubrication oil shortage determination time t1 or over (S21), during EV running from the time of determination that EV running time lubrication control is needed in S11 and S13, under the condition of EV running that the engine is separated from wheels by clutch releasing and stopped. When a lubrication oil retention determination time t2 elapses from engine startup (S22) for lubrication (S26), engine operation for lubrication is stopped (S27), to prevent engine operation for lubrication in vain. |
