PROBLEM TO BE SOLVED: To ensure a large retard amount of ignition timing retard for a catalyst heater in cold start of an internal combustion engine 1.SOLUTION: An internal combustion engine 1 is connected to a motor and generator 4 through a first clutch 3, and further connected to a continuously variable transmission 7 through a second clutch 6. The continuously variable transmission 7 has a CVT oil pump 15 mechanically driven, and a CVT electric oil pump 16 subjected to motor drive. In ignition timing retard, discharge pressure is reduced through a pressure adjustment valve 17, and thereby a load of the CVT oil pump 15 is reduced, and at the same time, increase correction of a retard amount compatible with the reduction is performed.SELECTED DRAWING: Figure 1 |
