The invention discloses a torque distribution method of a hybrid electric vehicle. The torque distribution method comprises the following steps that vehicle driving torque is determined according to the vehicle driving demand in a hybrid power mode; a plurality of set torque distribution values of an engine are obtained according to the vehicle driving torque; the equivalent fuel consumption rates of the engine and a motor are obtained according to the set torque distribution values; the effective fuel consumption rate corresponding to the vehicle driving torque only provided by the engine, of the engine is obtained when the torque is not distributed; the equivalent fuel consumption rate is compared with the effective fuel consumption rate of the engine, the corresponding set torque distribution value is a favorable torque distribution value and torque distribution is performed according to the favorable torque distribution value if the equivalent fuel consumption rate is lower; the corresponding set torque distribution value is an unfavorable torque distribution value and torque distribution is not performed if the effective fuel consumption rate is lower. According to the scheme, the equivalent fuel consumption rate of a whole power assembly serves as a reference so as to obtain the favorable torque distribution value for torque distribution implementation and enable the vehicle to be always operated at a lowest energy consumption point, and the economical efficiency of the whole vehicle is improved.
