ABSTRACT:
A control system for a vehicular automatic transmission which detects running status of the vehicle and includes a shift controller for controlling the gear stage of the automatic transmission in accordance with the detected running status of the vehicle. The control system further includes a memory for prestoring road information for roads to be run by the vehicle, present location detection and running direction detection. A reader reads out the road information for a set route from the present location to a destination, from the memory, on the basis of the detected present location and the destination input. The engine power required for the vehicle to travel the set route is estimated in accordance with the read road information. A shift schedule which minimizes the fuel consumption on the set route is determined by comparing the estimated engine power requirement with a prestored mileage map and the shift control pattern is changed in accordance with the determined shift schedule.
