Front and rear axle torque distribution method and device of vehicle

The invention relates to the technical field of vehicle control, and provides a front and rear axle torque distribution method and device of a vehicle. The front and rear axle torque distribution method comprises the steps of obtaining the real-time front-row seat bearing mass and the real-time rear-row seat bearing mass of the vehicle; calculating a front axle load and a rear axle load of the vehicle based on the front-row seat bearing mass and the rear-row seat bearing mass; determining a front axle torque distribution ratio and a rear axle torque distribution ratio according to the calculated front axle load and the rear axle load; and controlling the front axle and the rear axle to output torque according to the determined front axle torque distribution ratio and the determined rear axle torque distribution ratio. The method can cope with random changes of axle loads of the front axle and the rear axle of the vehicle, and can improve the power performance of the vehicle through the adaptively-changed torq
