摘要： An MG1-ECU (610) and an MG2-ECU (620) are provided independently for respective motor generators (MG1, MG2). The MG2-ECU (620) performs electric power balance control by correcting an MG2 torque command value as required, so that the sum of the MG1 electric power and the MG2 electric power is within a range of allowable input/output electric power (Win to Wout) of a DC power supply (510). The electric power balance control is performed using an estimate of the MG1 electric power based on data obtained by the MG1-ECU (610). The estimate is determined so that a communication delay time between the MG1-ECU (610) and the MG2-ECU (620) is corrected. In this way, the electric power balance control can be performed appropriately for restricting, within a predetermined range, the total input/output electric power of the electric motors as a whole of a hybrid vehicle mounted with a plurality of motor generators (electric motors).
