DRIVE CONTROL DEVICE OF HYBRID VEHICLE

Objects of the present invention is to improve the control accuracy of the charge state of a 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. According to the present invention, there is provided a drive control device of a hybrid vehicle in which an electric power loss predicting means and a target electric power calculating means are arranged, a target engine power calculating means calculates target engine power based on target driving power, target charge/discharge power, and estimated power that is an electric power loss, and a 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 and an electric power balance equation including the target electric power. In the electric power balance equation, electric power generated or consumed by the plurality of motor generators, the estimated power that is the electric power loss, and input/output electric power of the battery are included.
