PURPOSE:To reduce speed changing shock by switching the 1st output changing means varying the engine output by adjusting a suction air weight and the 2nd output changing means varying the engine output by adjusting combustion state according to the load. CONSTITUTION:The engine output control at speed changing time is performed by the throttle control as for a 1st output changing means C and the air-fuel ratio control as for a 2nd output changing means D and also used by switching it according to the load (boost pressure). The large transmission gear torque at speed changing time in a high load state is thus constrained by a large output variation by the operation of the 1st output changing means C, the protection of the friction material of the clutch, etc., of an automatic gear can be realized, the small transmission gear torque at speed changing time in a low state is constrained by a small output variation by the operation of the 2nd output changing means D and the speed changing shock can be reduced. |
