The invention provides a vehicle braking force distribution method and system, and the method comprises the steps: determining the braking force of each axle according to the braking force deceleration of the vehicle, the whole vehicle mass and the braking force distribution coefficient of each axle of the vehicle when a braking deceleration request of the vehicle is detected; calculating the vertical load variation of the axle according to the anti-braking nodding rate and the braking force of the axle; obtaining vehicle information of the vehicle, a first longitudinal distance between an axle and the center of mass of the vehicle, and a second longitudinal distance between each axle and each other axle; determining the vertical load of each axle according to the vehicle information, the anti-braking nodding rate of each axle, the braking force, the first longitudinal distance and the second longitudinal distance from each other axle; calculating the total vertical load of each axle according to the vertical load variation of the vertical load of each axle; and the target braking force of each axle is determined according to the slip rate and the total vertical load of each axle, and the target braking force of each axle is distributed to the corresponding axle.

    本申请提供一种车辆的制动力分配方法及系统,当检测到车辆的制动减速度请求时,根据车辆的制动力减速度、整车质量和车辆的每个车轴的制动力分配系数,确定每个车轴的制动力;根据车轴的抗制动点头率和制动力计算车轴的垂向载荷变化量;获取车辆的车辆信息、车轴距离车辆的质心的第一纵向距离、每个车轴距离每个其他车轴的第二纵向距离;根据车辆信息、每个车轴的抗制动点头率、制动力、第一纵向距离和距离每个其他车轴的第二纵向距离,确定每个车轴的垂向载荷;根据每个车轴的垂向载荷垂向载荷变化量计算每个车轴的总垂向载荷;根据每个车轴的滑移率和总垂向载荷确定每个车轴的目标制动力,将每个车轴的目标制动力分配给对应的车轴。
