PROBLEM TO BE SOLVED: To suppress the temporal deterioration of rotation speed of an engine when creep traveling is started.SOLUTION: In a vehicle 10, the power of an engine 12 is transmitted to an automatic transmission through a torque converter. When the opening of an ISCV 42 is controlled for creep traveling of the vehicle 10, an engine ECU 54 calculates a ratio of the rotation speed of a turbine runner 56t when the stepping-on of a brake pedal 50 is released to the rotation speed of the engine 12 as a present speed ratio. The engine ECU 54 refers to a table 54t indicating a corresponding relationship between a plurality of speed ratios and a plurality of suction air correction amount to obtain suction air correction amount corresponding to the present speed ratio, and corrects the opening of the ISCV 42 according to the obtained suction air correction amount.SELECTED DRAWING: Figure 1 |
