Abstract: The setting unit sets a first target valve-opening timing to be set when a load of the internal-combustion engine is within a first range which is a predetermined range later than both a second target valve-opening timing to be set when the load is within a second range in which the load is lower than the first range, and a third target valve-opening timing to be set when the load is within a third range in which the load is higher than the first range.

Abstract: If a vehicle speed is less than a predetermined value when a hybrid control mode is a series mode and a charge mode is selected (S10-S14), it is determined whether an SOC of a high voltage battery is less than a predetermined value or not (S16), and when the SOC of the high voltage battery is less than the predetermined value, ignition timing is corrected to be retarded (S18).

Abstract: In a case where a vehicle is in a steady running state or in a slow acceleration state, opening of an electric waste gate valve is set so that an actual air flow rate becomes minimum. Then, a feedback control is applied to opening of an electronically controlled throttle valve so that an actual amount of intake air generates output torque of an engine corresponding to an engine load. When the electronically controlled throttle valve is fully opened, while opening of the electronically controlled throttle valve is maintained, the feedback control is applied to opening of the electric waste gate valve so that output torque of the engine corresponds to an engine load, or an actual amount of intake air becomes a target amount of the intake air.
