Abstract
A shift control system for an automatic transmission of a vehicle controls the output of the engine according to the running condition of the vehicle when gear-shifting operation of the automatic transmission is detected. A shifting condition signal representing an actual value of the running condition during a gear-shifting operation is compared with a reference value signal representing a reference value of the running condition during the gear-shifting operation, and a correction signal is output on the basis of the result of the comparison. The controlled variable of the engine output power is corrected on the basis of the correction signal.
