Abstract
A control apparatus for a hybrid vehicle provided with an electrically operated continuously-variable transmitting portion and a step-variable transmitting portion, which control apparatus permits an adequate control of a shifting action of the step-variable transmitting portion, while reducing deterioration of fuel economy of the hybrid vehicle. The control apparatus is configured to implement concurrent controls of a movement of an operating point of an engine and a shifting action of the step-variable transmitting portion, such that ratios of change rates of rotating speeds of first, second and third rotary elements of a differential mechanism are respectively equal to ratios of differences between present actual values of the rotating speeds of the first, second and third rotary elements and target values of the rotating speeds of the first, second and third rotary elements to be established after the shifting action, so that a shifting shock of the step-variable transmitting portion can be reduced while controlling an electric power generation/consumption balance to a desired value.
