Abstract
An automatic transmission control system for controlling an automatic transmision for use in a vehicle provided with a throttle control system which electrically controls a throttle valve to control the engine output according to the amount of depression of the accelerator pedal and a constant-speed cruising control system which makes the vehicle cruise at a desired constant speed includes a first gear-stage setting system which designates a gear stage of the automatic transmission on the basis of a first gear-shifting pattern, which applies when the constant-speed cruising control is not performed, and in which the gear stages of the automatic transmission are related to the detected amount of depression of the accelerator pedal and the vehicle speed or a value corresponding to the vehicle speed, and a second gear-stage setting system which designates a gear stage of the automatic transmission on the basis of a second gear-shifting pattern, which applies when the constant-speed cruising control is performed in which the gear stages of the automatic transmission are related to the vehicle speed or a value corresponding to the vehicle speed, and a variable independent of the detecte…
