Abstract
A speed change control method controls changeover between gearshift positions of an automotive automatic transmission using a detected running condition parameter and a detected degree of necessity of engine braking. The degree of necessity of engine braking is detected using a neural network receiving the detected parameter as an input. Then, a shift pattern is preferably selected by fuzzy inference based on the detected parameter and degree of necessity of engine braking.
