Abstract
A control apparatus for a vehicle that includes a power transmission apparatus including a frictional engagement element configured to connect and disconnect transmission of a power between a drive power source and drive wheels of the vehicle. The control apparatus is configured to execute a vibration suppression control for estimating torsional vibration of the power transmission apparatus, based on a preformulated vibration model, and controlling a torque of a rotating machine that is connected to the power transmission apparatus, so as to suppress the torsional vibration. The control apparatus allows execution of the vibration suppression control, when the frictional engagement element is in an engaged state, and also when a differential rotation of the frictional engagement element has become smaller than a predetermined determination value even with the frictional engagement element being in a disengaged state.
