  "textContent": "There is provided a vehicle control device capable of accurately determining start of a torque phase in a shift operation. The vehicle control device controls a vehicle drive apparatus, which includes an input member drive-coupled to a driving force source, an output member drive-coupled to wheels, and a transmission having a plurality of engagement elements and a plurality of shift speeds in a switchable manner, wherein the vehicle control device controls switching of shift speeds, which is performed via a torque phase Pt, by controlling engagement and release of the plurality of engagement elements. The vehicle control device includes release control means for feedback controlling supplied oil pressure to a release side element so that a differential rotation speed N becomes substantially constant, engagement control means for increasing supplied oil pressure to an engagement side element in a state that the differential rotation speed N is substantially constant, and phase determining means for determining that the torque phase Pt 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.",
