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 R, Rare expanded to be larger than the retardation quantities R, Rin the engine idling mode. Thus, a rise in an exhaust temperature of the engine is promoted.
