The objective of the present invention is, with consideration for the electrical power loss of a plurality of motor generators, to increase the control precision of battery SOC, and thereby to secure battery protection performance and increase regenerative energy recovery efficiency. The drive control device of a hybrid vehicle is provided with a means for computing a motor torque command value, and is equipped with a means for estimating electrical power loss, a means for calculating an electrical power maximum/minimum value, and a means for calculating a target electrical power. The means for computing a motor torque command value calculates a torque command value of each of the plurality of motor generators using an electrical power balancing formula containing a target electrical power and a torque balancing formula containing a target engine torque determined from a target engine operating point. |
