Abstract:
1. A vehicle control device for controlling a vehicle drive apparatus, which includes an input member drive-coupled to a rotary electrical machine as a driving force source, an output member drive-coupled to a wheel, and a transmission having a plurality of engagement elements and a plurality of shift speeds in a switchable manner, shifting a rotation speed of the input member with speed ratios of the shift speeds and transmitting the shifted speed to the output member, wherein the vehicle control device controls switching of shift speeds, which is performed at least via a torque phase in the transmission, by controlling engagement and release of the plurality of engagement elements, the vehicle control device comprising: a phase determining mechanism for determining end of the torque phase in a shift operation; a rotary electrical machine control mechanism for controlling torque of the rotary electrical machine using a variation of input torque, which is derived so that a rotation speed change rate of the input member becomes a target rotation speed change rate, so as to increase or decrease input torque inputted to the input member by the variation of the input torque according to a direction of switching of shift speeds after the phase determining mechanism determines that the torque phase has ended; and an engagement control mechanism for feedback controlling supplied oil pressure to an engagement side element as an engagement element on a side to be engaged after switching of shift speeds so that the rotation speed change rate of the input member becomes the target rotation speed change rate.
