<p><P>PROBLEM TO BE SOLVED: To provide a control device of a vehicle, capable of improving fuel economy without an engine stall during warming-up and further preventing deterioration of drivability at the end of fuel cut control. <P>SOLUTION: The engine control device calculates, during execution of the fuel cut control, a target intake air quantity Qat from a basic intake air quantity Qabase and an additional intake air quantity Qaadd according to an auxiliary torque (step S14). Next, the engine control device sets, upon acquisition of a cooling water temperature Tw (step S15), a lower limit intake air quantity Qamin (step S16). The engine control device updates the target intake air quantity Qat with the lower limit intake air quantity Qamin (step S18) when the target intake air quantity Qat is smaller than the lower limit intake air quantity Qamin (NO in step S17), and adjusts a throttle opening so that an actual intake air quantity Qa is equal to the target intake air quantity Qat (step S19). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
