Traction distribution method and system of power-distributed train

A system for tractive force distribution for a power-distributed train, comprising:

• a determination unit configured to determine a current motor car of a target train;
• an acquisition unit configured to acquire parameter information of the current motor car, wherein the parameter information acquired by the acquisition unit comprises a mass, a current acceleration, a current resistance, a current tractive force, and a structural dimension of the current motor car;
• a first calculation unit configured to calculate, based on the parameter information, axle load transfer at four axles of the current motor car;
• a second calculation unit configured to, for each of the four axles of the current motor car, calculate, based on the axle load transfer at the four axles, a current axle load on the axle of the current motor car, wherein increased axle load transfer at the axle indicates a decreased axle load on the axle, and decreased axle load transfer at the axle indicates an increased axle load on the axle;
• and
• a distribution unit configured to adjust, based on current axle loads on the four axles, distribution of a tractive force applied to each of the four axles of the current motor car using an electrical control compensation technology, wherein the electrical control compensation technology comprises:
• for each of the four axles of the current motor car,
• if the axle load on the axle is decreased, decreasing an output torque of a traction motor arranged at the axle based on a decrease amount of the axle load, and
• if the axle load on the axle is increased, increasing an output torque of a traction motor arranged at the axle load based on an increase amount of the axle load.
