PROBLEM TO BE SOLVED: To suppress an acceleration response delay feeling which is generated by the prolongation of a gear change time at a down-shift.SOLUTION: When maximum torque (A) during a gear change period which influences a gear change time TMsh at a down-shift is set relatively small since an estimated intake air amount Qairp at down-shift determination is relatively small, and when the gear change time TMsh is elongated relatively long, it becomes easy to perform such gear change control that a vehicle is gear-changed to a required gear stage Gdem after the vehicle is gear-changed once to a gear stage G at a high-vehicle speed side rather than the required gear stage Gdem. Accordingly, an acceleration response delay feeling which is generated by the prolongation of the gear change time TMsh at the down-shift, (in other words, a period in which a power transmission amount through an automatic transmission 18 is reduced is elongated), can be suppressed. |
