PROBLEM TO BE SOLVED: To suppress the shock due to abrupt power transmission in automatically starting caused by an incomplete state of a power transmission mechanism in an internal combustion engine equipped with a transmission where in the inside power transmission mechanism can function by an energy source except for the internal combustion engine in stopping the internal combustion engine. SOLUTION: When the engagement hydraulic pressure of a C1 clutch is not sufficient in the automatic stop due to abnormality in an electric oil pump, etc., there is a possibility that the engagement hydraulic pressure abruptly increases by the oil pump incorporated in the A/T after the automatic start so as to cause en engagement shock caused by the C1 clutch. Therefore, in this case, it falls under (S350 and 'YES'), if an acceleration pedal is treaded, (S390 and 'YES'), an idle throttle opening TAecoidl is set to (=0%) (S410) to minimumize the output torque of the engine. This constitution prevents direct transmission of the large output torque from the engine to the whole A/T and the output side of the A/T. The problem is thus solved. |
