ABSTRACT:
A drive control system for starting an internal combustion engine of a hybrid vehicle running while transmitting the output of an electric motor to a power transmission line for the run, by coupling the internal combustion engine to the power transmission line. The drive control system comprises: a start demand deciding unit for deciding a demand for the start of the internal combustion engine; and an assist setting unit for raising the output torque of the electric motor, when the demand for starting the internal combustion engine is decided by the start demand deciding unit, by a torque corresponding to either a motoring torque necessary for rotating the internal combustion engine or a summed torque of the motoring torque and an inertia torque according to the changing rate of the revolution speed of the internal combustion engine.
