A method for controlling a full load mode of a hybrid vehicle by a controller may include: calculating driver demand torque based on acceleration pedal position sensor (APS) information or brake pedal position sensor (BPS) information; predicting the driver's acceleration/deceleration information based on the hybrid vehicle's driving information; predicting the driver demand torque based on the predicted acceleration/deceleration information; predicting a state of charge (SOC) of a battery that supplies electric power to a motor for driving the hybrid vehicle, based on the calculated driver demand torque and the predicted driver demand torque; and controlling an engine for charging the battery based on the predicted battery SOC, in order to keep the hybrid vehicle from entering into the full load mode in which the engine configured to produce a maximum torque and the motor are used.
