Abstract
An engine control device, while executing a fuel-cut control, calculates a target intake air amount (Qat) from a basic intake air amount (Qabase) and an added intake air amount (Qaadd) commensurate with an accessory torque (step S). Next, the engine control device acquires a coolant temperature (Tw) (step S), and then sets a lower-limit intake air amount (Qamin) (step S). When the target intake air amount (Qat) is smaller than the lower-limit intake air amount (Qamin) (NO in step S), the engine control device updates the target intake air amount (Qat) with the lower-limit intake air amount (Qamin). (step S), and adjusts the degree of throttle opening so that the actual intake air amount (Qa) becomes equal to the target intake air amount (Qat) (step S).
