Abstract
An ECU controls an automatic transmission that can be manually shifted. The ECU executes a program that includes i) the step of, when there are a plurality of allowed gears that are allowed at the time of a downshift operation, continuously determining whether the engine speed NE after a downshift will be in a preset overspeed region for each allowed gear when the second and subsequent allowed gears are lower than an output gear, and when there is an allowed gear that will result in the engine speed NE being in the overspeed region, ii) the step of cancelling that allowed gear. Thus this control appropriately suppresses overspeeding of the engine while executing a manual shift in response to an operation by the driver without bothering the driver.
