The invention relates to a torque distribution method and system applied to an unmanned container truck and a medium, and the method comprises the steps: U1, enabling a vehicle to run on a road, obtaining the vehicle speed data information of front and rear wheels in real time based on a vehicle-mounted wheel speed sensor, and obtaining the rotation speed data information of front and rear wheel driving motors in real time based on a vehicle-mounted driving motor rotation speed sensor; and U2, based on the vehicle speed data information of the front and rear wheels, calculating the effective vehicle speed of the whole vehicle by adopting an improved anti-interference average value filtering algorithm to obtain effective vehicle speed data information of the whole vehicle, and based on the rotating speed data information of the driving motor of the front and rear wheels, calculating the driving vehicle speed corresponding to the motor by adopting a driving motor mapping vehicle speed algorithm to obtain the effective vehicle speed data information of the whole vehicle. And front and rear wheel driving motor mapping vehicle speed data information is obtained. Self-adaptive distribution of torque is achieved, the self-adaptive performance of the vehicle to different operation scenes is improved, and the situation that vehicle driving wheels excessively slip and are abraded in the running process, and durability loss of the wheels is caused is avoided.
