摘要:
A vehicle drive apparatus is disclosed having a differential mechanism and an electric motor provided in the differential mechanism for miniaturizing the drive apparatus or improving fuel consumption while suppressing the occurrence of shifting shocks. A switching clutch C0 or switching brake B0 is provided for placing a shifting mechanism 10 in a continuously variable shifting state and a step variable shifting state, enabling the drive apparatus to have combined advantages including a fuel economy improving effect of a transmission, enabled to electrically change a speed ratio, and a high transmitting efficiency of a gear type transmitting device enabled to mechanically transmit drive power. During a shifting of an automatic shifting portion 20 with a differential portion placed in a continuously variable shifting state, engaging pressure control means 84 controls a engaging pressure of a engaging device of the automatic power shifting portion 20 such that a rotational speed N18 of a transmitting member achieves a given variation so as to provide a compromise between a rapid shifting response on a feeling and a slow shifting response on the shifting shocks, thereby suppressing the occurrence of the shifting shocks.
