The control system for a hybrid vehicle configured to ensure acceleration of the vehicle is provided. When accelerating the vehicle quickly, a torque command to an engine is calculated by adding a torque corresponding to an inertia torque of the engine that is required to increase an engine speed to the required engine torque. In this situation, a controller controls the engine in such a manner as to generate torque based on the calculated torque command, and controls a motor in such a manner as to generate reaction torque against a required engine torque.
