Abstract
A vehicle control system to improve acceleration response and shift feel by executing a power-on downshifting in a suitable manner. An evaluation of a skip shifting and an evaluation of a stepwise shifting are compared to each other when executing the downshifting, based on an evaluation index calculated in advance in accordance with an operating condition of an accelerator. The downshifting operation to be executed is selected from the stepwise shifting and the skip shifting whose evaluation is higher than the other one.
