<P>PROBLEM TO BE SOLVED: To provide a battery power compensation controller of a hybrid vehicle in which a feeling of physical disorder is prevented from being given to an operator due to deficiency of acceleration feeling while attaining overcharge/overdischarge power compensation at the time of overcharge/overdischarge power compensation of a battery under acceleration state. <P>SOLUTION: In a hybrid vehicle having a power source of at least two motor-generators MG1 and MG2 employing an engine E and a battery 4 as a power supply, and provided with a speed change gear including a differential gear having the degree of freedom of 2 such that all remaining rotational speeds are determined when the rotational speed of two out of the power source and the output members to tires are determined, there are provided a means 63 for detecting or estimating charge/discharge power of the battery 4, a means 65 for estimating or detecting acceleration state of the vehicle, and a means 64 for compensating overcharge/overdischarge power of the battery when battery power enters overcharge/overdischarge state under acceleration state and correcting engine torque and motor generator torque not to decrease acceleration in the advancing direction of the vehicle. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
