The invention discloses a torque distribution method of a hybrid vehicle. The method comprises the following steps: obtaining the state of charge (SOC) of a power battery of the hybrid vehicle, a rotary speed n of the input end of a gear box of the hybrid vehicle and a required torque tr of the input end of the gear box; obtaining first, second, third, fourth and fifth torques ta, tb, tc, td and te according to the rotary speed n of the input end of the gear box and a five-line five-area characteristic curve of the hybrid vehicle; and subjecting an engine and a motor of the hybrid vehicle to torque distribution according to the required torque tr of the input end of the gear box and the first, second, third, fourth and fifth torques ta, tb, tc, td and te. The torque distribution method uses the five-line five-area characteristic curve to optimize the torque distribution between the engine and the motor, and the fuel economical efficiency of the hybrid vehicle is greatly increased. The invention also discloses the hybrid vehicle.
