ABSTRACT:
An output torque control system for an internal combustion engine for a vehicle is operable during an upshift of an automatic transmission of the engine to increase the output torque from the engine, based on a control amount for increasing the output torque, to reduce a shock generated by the upshift. During the upshift of the automatic transmission, a slip amount of one of a plurality of clutches of the automatic transmission which is selected for the upshift is compared with a predetermined value. A calculation is made of a value of the control amount assumed when the slip amount of the one clutch becomes equal to the predetermined value, as a result of the comparison. The control amount is limited to the calculated value when the slip amount exceeds the predetermined value, as a result of the comparison.
