PROBLEM TO BE SOLVED: To prevent degradation in reliability due to failure in oil film formation at the starting of an engine. SOLUTION: Engine torque is corrected with K value so that the cranking resistance of an engine and the engine torque may be balanced as shown in (3) as compared with a case (1) of cranking by an ordinary engine or a case (2) of cranking by a hybrid vehicle engine. As a result, the rising speed of the engine is lowered, and the rising degree of the engine speed at cranking is corrected in the lowering direction. |
