Abstract
A drive control system for a hybrid vehicle in which an internal combustion engine is selectively coupled through a clutch mechanism to a power transmission line coupled to an electric motor. The drive control system comprises: motoring device for coupling the engine to the power transmission line to rotate the engine, with the feed of a fuel to the engine being stopped when the hybrid vehicle is driven to run by the output of the electric motor, by controlling the clutch mechanism in an applied state. Thus, it is possible to start the engine even at a low speed of the hybrid vehicle and to prevent the deterioration in the riding comfort, as might otherwise be caused by the fluctuation in a driving torque.
