Abstract

An engine shaft of an engine, rotatable shafts of two motor generators and a drive force output shaft are interconnected with each other through a drive force transmission arrangement. When a torque of one of the motor generators is limited, an ECU computes a torque correction amount of the other one of the motor generators in a manner that limits at least one of a change in a torque of the engine shaft, a change in a torque of the drive force output shaft and a change in an output of a battery based on a torque limit amount of the one of the motor generators and corrects the torque of the other one of the motor generators with the computed torque correction amount.
