ABSTRACT:
A shift control system detects a traveling resistance as a factor influencing the vehicular driving performance. The shift control system varies preset shift pattern according to the detected traveling resistance of the vehicle for optimizing selection of the shift pattern. The shift control system thus controls the speed ratio of an automatic power transmission depending upon the control parameters, such as an engine load and a vehicle acceleration.
