PROBLEM TO BE SOLVED: To attain, when torque including an oscillating component is demanded for specific vehicle control and an efficient demand is also made for vehicle control other than the specific vehicle control, torque and efficiency according to the demands without fluttering a throttle. SOLUTION: Model torque for the specific vehicle control is generated in conjunction with the generation of specific demand torque including the oscillating component, and the ratio of the specific demand torque to the model torque is calculated as specific demand efficiency. A value obtained by multiplying the specific demand efficiency by other demand efficiency is calculated as total demand efficiency. Then, demand potential torque obtained by dividing the specific demand torque by the total demand efficiency is converted to a cylinder air amount necessary for its attainment, and an opening degree command value to the throttle is determined based on the cylinder air amount. Further, estimated potential torque when the throttle is operated according to the opening degree command value is calculated, and ignition timing is determined using a ratio of the specific demand torque to the estimated potential torque as indicated efficiency.
