Abstract

An electronic control unit engages two of friction engagement elements provided in an automatic transmission in a neutral range. The electronic control unit disengages one of the two friction engagement elements engaged in the neutral range at the time of starting gear stage switching of an auxiliary transmission from a low-speed gear stage to a high-speed gear stage in the neutral range, and re-engages the friction engagement element that has been disengaged when determining that the gear stage switching has been completed.
