ABSTRACT:
The present invention relates to a control device for a vehicular drive system which properly controls a shift in a transmission portion upon receipt of a shift demand to the transmission portion for precluding a given element of the differential portion11from high rotation. For a shift demand to an automatic transmission (20), the transmission portion shift limiting means (86) determines a permissible range in terms of a speed ratio of an automatic transmission (20) in consideration of a rotational speed of a given element of a differential portion (11) for thereby limiting a shifting of the automatic transmission portion (20) based on the permissible range. Thus, when the shift demand to the automatic transmission (20) is present, the given element of the differential portion (11) can be avoided from high rotation. This enables the suppression of the high ration of, for instance, first and second electric motors (M1), (M2) and a first planetary gear (P1) or the like, improving durability of the first and second electric motors (M1), (M2) and the first planetary gear (P1) or the like.
