Abstract
When the accelerator pedal is fully depressed, shifting points at which the automatic power transmission shifts to another gear ratio are suddenly moved toward the higher vehicle speed to readily achieve the downshift of the transmission even during a relatively high vehicle speed. The downshifts are continued until the magnitude of the throttle pressure which is substantially proportional to the output of the engine is decreased to a predetermined level even when the accelerator pedal is permitted to return to its partially depressed position.
