Abstract
A control system for an automatic transmission includes a route information detector which detects route information for the vehicle and a transmission which is controlled by the route information detector. The control system also includes a device for detecting the places where it is necessary to decrease speed in the determined traveling distance, a device for calculating the vehicle target speed for each corner, a device for calculating the required vehicle speed at the present position of the vehicle to decrease present vehicle speed to the vehicle target speed for the place where it is necessary to decrease speed. And if the target deceleration from the present speed to the required vehicle speeds lager than a threshold value, the place is regarded as the target place, and it is counted as the target place, and the automatic transmission is shifted down.
