PROBLEM TO BE SOLVED: To restrain the deterioration of the durability of a transmission caused by changeover from a neutral position in the duration of vehicle traveling to a forward traveling position.SOLUTION: In the duration of vehicle traveling in a state that a neutral position is selected and all clutches or the like of an automatic transmission are released, a shift position SP is shifted to a forward traveling position (S110) from the neutral position, and when it is determined that there is a risk that there may arise an over-rotation state of a sun gear of a Ravigneaux type planetary gear mechanism constituting the automatic transmission accompanied by engagement with the clutch (first element) which s firstly engaged out of the two clutches corresponding to a determination objective gear change stage Gd (S150), the engagement of the two clutches corresponding to the determination objective gear change stage Gd being a tar gear change stage Gtag can be delayed (S160-S180, S205, S210). |
