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.

[ What is claimed is:] [1.]1. A drive control system for a hybrid vehicle, which has a torque synthesizing/distributing mechanism for synthesizing an output torque of an electric motor and an output torque of an internal combustion engine and for outputting a synthesized torque therefrom, comprising:target engine speed detecting means for determining a target speed of the engine on the basis of an output demand for the engine and an output speed of said torque synthesizing/distributing mechanism;target motor speed detecting means for determining a target speed of the motor on the basis of the target speed of the engine and the output speed of said torque synthesizing/distributing mechanism;engine output control means for controlling the output of the engine to the output torque which is determined on the basis of the output demand for the engine and the target speed of the engine; andmotor speed control means for controlling an output speed of the motor to the target motor speed which is determined by said target motor speed detecting means.
