Abstract
A system for integrally controlling an automatic transmission and an engine, wherein gear stages are automatically switched in accordance with a preset shift map, and an engine torque is changed by a predetermined change value during shifting to thereby maintain the satisfactory shift characteristics. The system includes a device for determining whether or not an engine torque change can be actually carried out without a problem; and means for regulating said engine torque change when said engine torque change cannot be actually carried out, to thereby prevent the problem from occurring.
