Abstract:
1. A control apparatus for a vehicular drive system including an electric differential portion and a mechanical power transmitting portion which are disposed in series in a power transmitting path between an engine and a drive wheel of a vehicle, said control apparatus being configured to limit an output of said engine according to a difference between an actual rotating speed of said mechanical power transmitting portion, and a theoretical rotating speed estimated from a presently established speed ratio of the mechanical power transmitting portion; wherein said electric differential portion includes a differential mechanism operable to distribute the output of said engine to a first electric motor and an input shaft of said mechanical power transmitting portion, and a second electric motor connected to said input shaft, said control apparatus comprises first-electric-motor-speed control means configured to control a rotating speed of said first electric motor such that a rotating speed of said second electric motor does not exceed a predetermined upper limit.
