  • Patent number: 9090251
    Abstract: An idling revolution speed control which maintains an engine speed at a predetermined target idling revolution speed during the idling drive includes an engine idling mode which performs the idling revolution speed control through an engine and a motor idling mode which performs the idling revolution speed control through a motor. The two modes are switched in accordance with a battery charged state. During the idling drive in an engine cold state, an ignition timing of the engine in the motor idling mode is retarded and the retardation quantities R3, R4 are expanded to be larger than the retardation quantities R1, R2 in the engine idling mode. Thus, a rise in an exhaust temperature of the engine is promoted.
