<P>PROBLEM TO BE SOLVED: To provide a system for following up an engine operation point of a hybrid vehicle, which improves an engine operation point follow-up performance in the state of the performance of a speed control to a first motor being lowered. <P>SOLUTION: The system includes: an engine; two motors; and two pairs of planetary gear sets. The system is constituted, also including: an engine target speed changing part changing an engine target speed into a first motor target one; a PI controlling part converting the first motor target speed into a torque value; an anti-wind-up feedback part feeding back the shortfall of the first motor torque to an engine torque compensation part; a torque conversion calculating part converting the shortfall of the first motor torque into an engine torque value; and an engine torque compensation part compensating an engine target torque by adding the converted engine torque, and making an engine operation point follow up an engine target speed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
