Patent ID: 8666636

Claim:
A control apparatus for a supercharged internal combustion engine, comprising: means for determining a target torque to be outputted to the supercharged internal combustion engine; means for determining a target air quantity from the target torque; means for determining a target boost pressure from the target torque; means for controlling an operation of an actuator for air quantity control according to the target air quantity; and means for controlling an operation of an actuator for boost pressure control according to the target boost pressure, wherein: the target torque determining means forms the target torque by using a low-frequency torque component set at all times based on a torque requirement from a driver and a high-frequency torque component set as necessary for a specific type of vehicle control; and when the target torque contains only the low-frequency torque component, the target boost pressure determining means forms the target boost pressure by using a pressure component corresponding to the low-frequency torque component and, when the target torque contains the low-frequency torque component and the high-frequency torque component, the target boost pressure determining means forms the target boost pressure by using the pressure component corresponding to the low-frequency torque component and a pressure component corresponding to a fixed torque component with a value equal to or more than a maximum amplitude of the high-frequency torque component.
