<P>PROBLEM TO BE SOLVED: To provide a controller for a hybrid vehicle improving fuel economy while bringing an SOC (State Of Charge) close to a target. <P>SOLUTION: The controller for a hybrid vehicle is loaded on a hybrid vehicle, and includes: an internal combustion engine; rotation electrical machinery; an electricity accumulation means; a shift part; a feedback control means; and a control means. The electricity accumulation means supplies an electric power to the rotation electrical machinery, and charges the regenerative power of the rotation electrical machinery. The feedback control means performs the feedback control of state amounts corresponding to the electricity accumulation state of the electricity accumulation means based on a prescribed feedback gain. When generating an electric power by the rotation electrical machinery for increasing the torque of the internal combustion engine, and adjusting a driving power, the control means sets the feedback gain when the torque of the internal combustion engine is lower than torque on the optimal fuel economy operation line to be larger than the feedback gain when the torque of the internal combustion engine is higher than the torque on the optimal fuel economy operation line. <P>COPYRIGHT: (C)2011,JPO&INPIT |
