Abstract
A drive control apparatus for hybrid vehicles adapted to facilitate controlling a rotation speed of an internal combustion engine, preventing excess speeds of a motor generator. The drive control apparatus for hybrid vehicles is adapted for a drive control of a vehicle using outputs from an engine and motor generators, and includes a target engine operating point setter for setting up a target engine operating point to determine target engine torque and a target engine rotation speed of the engine from target engine power and an efficiency of system. A motor torque command value calculator sets up respective torque command values of the motor generators, and an engine torque corrector corrects the target engine torque by a target engine torque correction value set up based on the torque command values of the motor generators and permissible output torque of the motor generators.
