ABSTRACT:
In a system for integrally controlling an automatic transmission and an engine, having a pattern select switch, and wherein engine torque is changed by a predetermined change value to thereby maintain the satisfactory shift characteristics, at least one of an engine torque change performing region and an engine torque change value is corrected in accordance with the state of the pattern select switch. As a result, the optimal engine torque change during shifting can be constantly performed regardless of the operator-selected shift pattern.
