POWER OUTPUT APPARATUS, VEHICLE EQUIPPED WITH POWER OUTPUT APPARATUS, AND CONTROL METHOD OF POWER OUTPUT APPARATUS

摘要

The drive control of the invention sets a rotation speed Ni for in-cylinder injection according to an operation curve used in operation of an engine with fuel injection from only in-cylinder fuel injection valves and a rotation speed Np for port injection according to an operation curve used in operation of the engine with fuel injection from only port fuel injection valves (steps S150 and S160). The drive control subsequently sets a target rotation speed Ne* and a target torque Te* of the engine by distributing the rotation speed Ni for in-cylinder injection and the rotation speed Np for port injection by an allocation rate k of in-cylinder fuel injection to port fuel injection (step S170). The drive control then sets torque commands Tm1* and Tm2* of two motors and controls the engine and the two motors to drive the engine at a specific drive point defined by the target rotation speed Ne* and the target torque Te* and to ensure output of a torque demand Tr* to a ring gear shaft or a driveshaft (steps S180 through S220). This arrangement attains efficient and appropriate operation of the engine.
