Abstract
When a current downshift is determined to be a multiple downshift, it is determined whether or not a torque down during a first downshift is in a condition of interfering with learning performed for stabilizing the downshift operation during a second downshift is executed. If the torque down during the first downshift is determined to be in the condition of interfering with the learning, the learning is prohibited.
