Abstract
A controller ( ) estimates (calculates) an engine revolution speed of after shifting to a target gear position, based on vehicle speed and a gear ratio of an automatic transmission ( ) at the target gear position. Then, the controller ( ) changes the target gear position to a higher one when the calculated engine revolution speed is not less than a preset value. The controller changes the target gear position by one or more gears. Since the target gear position is raised, an engine does not overrun upon shifting down. If the target gear position is lower than a current gear position by one gear, and an engine overrun is expected, no shifting down is admitted.
