Abstract

A drive control device of a hybrid vehicle in which an electric power loss predictor and a target electric power calculator are arranged, a target engine power calculator calculates a target engine power based on a target driving power, target charging/discharging power, and estimated power that is an electric power loss, and a motor torque instruction value calculator calculates the torque instruction values of a plurality of motor generators using a torque balance equation including the target engine torque and an electric power balance equation including the target electric power. In the electric power balance equation, the 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.
