DRIVE CONTROL DEVICE OF HYBRID VEHICLE

Objects of the present invention is to improve the control accuracy of the SOC of the battery in consideration of the electric power losses of a plurality of motor generators and, in accordance therewith, to secure the protection performance of the battery and to increase the energy recovery efficiency according to the regeneration. In a drive control device of a hybrid vehicle including a motor torque instruction value calculating means, an electric power loss predicting means, an electric power upper limit/lower limit value calculating means, and a target electric power calculating means are arranged, and the motor torque instruction value calculating means calculates torque instruction values of a plurality of motor generators using a torque balance equation including target engine torque required at a target engine operating point and an electric power balance equation including target electric power.
