摘要： An automatic transmission control system, which applies an ordinary gear shift control map set up for flat road driving and a downgrade gear shift set up for downgrade driving which has broadened range of driving conditions for lower gears, causes gear shifts according to the ordinary gear shift control map even during downward driving when an accelerator pedal is stepped on with intention of accelerating the vehicle.

摘要： An automatic transmission control system causes a downshift to a gear which can provide an effect of engine braking greater than that provided before the downshift when the vehicle falls its speed with a specified rate of speed reduction as a result of footbrake application while the vehicle is traveling on a downgrade having a slope greater than a specified slope.
