A hybrid vehicle control apparatus is provided, wherein an unpleasant sensation is not imparted to a driver depressing an accelerator pedal at the time of departure. In a hybrid vehicle control apparatus with an engine and a motor as the drive sources, and a battery for storing electrical energy from the engine or the kinetic energy of the vehicle converted by the motor, the vehicle is provided with an automatic transmission. Moreover, there is provided a discharge suppression mode which suppresses discharge from the remaining battery charge detected by a battery ECU, and a charge/discharge permit mode which permits charge/discharge of the battery. At a time of vehicle departure, departure assistance is performed only when a degree of throttle opening showing an acceleration intention of the driver exceeds a determination threshold which is larger than a determination threshold for at the time of the discharge/charge permit mode.
