Whether output Pe is higher than allowable torque checked after deciding reduction of torque for the R range(140). Reduction of engine output torque is calculated when the condition is satisfied(150). Recognizing value of ignition time for reduction engine output torque is calculated(160). Final ignition time is calculated after reducing engine output torque(170). Control for quantity of fuel is added during controlling reduction of torque(180).
