The control system of the present invention is provided for a hybrid vehicle with an engine and a motor, which are power sources, and a power storage unit for storing energy generated by the output from the engine and regenerative energy produced by regeneration of the motor when the vehicle decelerates. Based on monitoring the state of charge of the power storage unit, when the stored energy is discharged so that the remaining charge is decreased from an initial state of charge, which was detected when the vehicle started running, by a predetermined amount, the function of the motor is switched from the discharging of the power storage unit to the charging of the power storage unit.
