摘要：
A shift control apparatus for controlling a speed ratio of an automatic transmission of a motor vehicle having an engine during running of the vehicle on a downhill road, on the basis of an actual acceleration value of the vehicle as compared with a reference acceleration value of the vehicle, the apparatus including a device for determining reduction of an actual output of the engine with respect to a desired output of the engine as represented by an operating amount of an accelerator pedal, and a device for reducing the reference acceleration value by a compensating amount which decreases with an increase in the running speed of the vehicle, upon determination of the reduction of the actual output of the engine.
