Abstract
A control apparatus includes a shifting delay control portion configured to delay a moment of generation of a shift-down command to implement a power-on shift-down action of the step-variable transmission, with respect to a moment of determination to implement the power-on shift-down action, for thereby reducing a shifting shock of the step-variable transmission in the process of the power-on shift-down action. The shifting delay control portion adjusts a delay time from the moment of determination to implement the power-on shift-down action to the moment of generation of the shift-down command, on the basis of at least one of an output state of the drive power source; an inertia power required in the process of the power-on shift-down action; a consumption power to be consumed by the coupling devices; and a state of a battery to and from which an electric power is respectively supplied from and to the motor/generator.
