PROBLEM TO BE SOLVED: To provide a vehicular drive apparatus capable of appropriately eliminating a difference between power input into a toroidal-type stepless transmission and required power.SOLUTION: A vehicular drive apparatus includes: an internal combustion engine for outputting power for a vehicle travels with; a toroidal-type stepless transmission for outputting at least the output of the engine by speed changing the output; a motor, disposed on an input side of the stepless transmission, for generating an auxiliary output for assisting the output of the engine and performing a regeneration operation using at least a portion of the output of the engine as power; a required power derivation part for deriving required power that is required as power for the input side of the stepless transmission; an output detection part for detecting the output of the engine; and a control part for controlling driving of the motor on the basis of a given drive control rule so that a difference between power input into the stepless transmission and the required power come close to zero ("0"), if there is a power deviation that is a difference of the required power relative to the output of the engine. The drive control rule includes: a first control rule in the case of a sign of the power deviation being positive; and a second control rule in the case of the sign thereof being negative.SELECTED DRAWING: Figure 1
