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 torque distribution proportion of the front axle and the rear axle.
本发明涉及车辆控制技术领域,提供一种车辆的前后桥扭矩分配方法及装置。本发明所述的前后桥扭矩分配方法包括:获取所述车辆实时的前排座椅承载质量和后排座椅承载质量;基于所述前排座椅承载质量和所述后排座椅承载质量,计算所述车辆的前桥轴荷和后桥轴荷;根据所计算的前桥轴荷和后桥轴荷,确定前桥扭矩分配比和后桥扭矩分配比;以及根据所确定的前桥扭矩分配比和后桥扭矩分配比,控制前桥和后桥进行扭矩输出。本发明能够应对车辆前后桥的轴荷的随机性变化,可以通过适应性变化的前后桥扭矩分配比例,提高车辆动力性能。
