Abstract

A shift control system of a hybrid transmission for a vehicle is arranged to correct ideal motor/generator torques so as to achieve a target engine speed prior to a target driving torque when an actual engine speed becomes greater than an allowable upper-limit engine speed and to correct the ideal motor/generator torque so as to achieve the target driving torque prior to the target engine speed when the actual engine speed does not become greater than the allowable upper-limit engine speed.
