Abstract
A control apparatus for a vehicular drive system arranged to electrically transmit a portion of an output force of an engine through an electric path. The control apparatus is configured to reduce loads of components associated with the electric path and to restrict a temperature rise of the components associated with the electric path, making it possible to reduce the required size of a cooling system. This is accomplished by placing a differential portion in a non-differential state or placing a switching clutch or switching brake in a partially engaged state when electrical energy through the electric path has increased to a thermal limit. As a result, the amount of generated electric energy is reduced, making it possible to restrict the temperature rise of the components associated with the electric path. Accordingly, the cooling system size can be reduced for these components.
