PURPOSE:To obtain sufficient shock reducing effect even at abnormal start operation by executing control for reducing engine output, control for reducing clutch transmitting torque capacity, and in addition at abnormal start operation control for transmission gear ratio of an automatic transmission so as to reduce output torque. CONSTITUTION:When start operation is executed at a moment (t1), if this operation is abnormal start operation by which the engine speed Ne exceeds 3000RPM due to racing of the engine. FLAG1 displaying abnormal start operation is set to one on the automatic transmission side. This state, PLAG1=1, is continued untill a prescribed period K has passed from the moment (t1), and during this period control for reducing clutch pressure and control for transmission gear ratio are executed. Meanwhile, on the engine side at abnormal start operation, at first, control for reducing engine output (control of numbers of cylinder) is executed. During this period, the automatic transmission output torque is further reduced, compared with the case of control for only reducing engine output or the case in which control for reducing engine output and control for reducing clutch pressure are simultaneously executed. |
