A multi-car train train brake force distribution method and system

The present application provides a multi-car train vehicle braking force distribution method for determining a current vehicle target multiple cars of a train; calculating a current vehicle axle, each axle load current; a positive correlation to the axle according to the current allocation of the respective axle current braking force of each axle of the vehicle. Utilized in the present application allocates the axle load compensation braking force of the respective axle, so that the axle braking force small play axle axle load is reduced according to the amount of load shedding, and increased axle axle braking force play by axle load increase, so that the axle braking force and play axles match, optimize adhesion utilization, the total braking force to ensure optimal play purposes.
