Speed change control method for an automotive automatic transmission.

摘要

A control section for controlling a gearshift position changeover mechanism of an automatic transmission includes a downshift determination section for determining whether or not a downshift on descending roads is required, and a downshift command section for outputting a downshift command signal when it is determined that downshift is necessary. The downshift determination section is provided with a learning correction section for effecting a learning correction of a determination reference based on a manipulation characteristic of a driver immediately after completion of downshift each time a downshift takes place.
