Abstract
A vehicle control device for controlling a vehicle drive apparatus, the vehicle control device configured with a release control mechanism that provides feedback controlling supplied oil pressure to a release side element, and an engagement control mechanism that increases supplied oil pressure to an engagement side element as an engagement element on a side to be engaged in a state that the differential rotation speed is substantially constant. The control device is further configured with a phase determining mechanism that determines if the torque phase has started when a condition that a phenomenon accompanying a change of the differential rotation speed due to increase of the supplied oil pressure to the engagement side element is detected is met.
