Abstract
A drive control system for a hybrid vehicle, in which the output torques of an electric motor and an internal combustion engine are synthesized by and outputted from a torque synthesizing/distributing mechanism. The target speed of the engine is determined on the basis of the output demand for the engine and the output speed of the torque synthesizing/distributing mechanism, and the target speed of the motor is determined on the basis of the target speed of the engine and the output speed of the torque synthesizing/distributing mechanism. The output of the engine is controlled to the output torque which is determined on the basis of the output demand for the engine and the target speed of the engine, and the output speed of the motor is controlled to the target speed.
