PROBLEM TO BE SOLVED: To allow a direct injection engine to be properly started by connecting a K0 clutch during MG creep cutting in which an LU clutch and a C1 clutch are maintained in connection states.SOLUTION: When a brake operation is performed during an MG creep mode for generating creep torque by a MG, MG creep cutting for causing MG torque to be 0 is performed while connecting an LU clutch 30 and a C1 clutch 18. Accordingly, consumption of a battery 44 is suppressed while securing response properties during starting. When there is an engine start request during the MG creep cutting, the LU clutch 30 is disengaged, and engagement torque of the C1 clutch 18 is reduced, and a K0 clutch 34 is engaged to perform assist by the MG when igniting and starting a direct injection engine 12. Accordingly, the direct injection engine 12 can be reliably and quickly started. Further, because self-sustained rotation is likely to be established during the ignition and starting, small assist torque of the MG is sufficient, and deterioration caused by over-discharging of the battery 44 is prevented. |
