The invention discloses a method for relieving braking nodding through a braking force distribution mode, and relates to the technical field of automobile braking. The braking force is distributed according to the axle load proportion of the front axle and the rear axle, and the braking force proportion of the front axle is obtained according to the front overhang compression deformation amount and the rear overhang compression deformation amount; and the optimal beta is obtained according to the formula of the front overhang compression deformation amount delta f1 and the formula of the rear overhang compression deformation amount delta f2 so as to restrain braking nodding. In the braking process, the axle load of the front axle is increased, the axle load of the rear axle is reduced, and the limit capacity of the front axle and the rear axle is determined by the axle load proportion; the braking force is distributed through the axle load proportion of the front axle and the rear axle, and the control stability in the braking process can be improved.

    本发明公开了一种通过制动力分配方式缓解制动点头的方法,涉及汽车制动技术领域;本发明根据前后轴轴荷比例对制动力进行分配,根据前悬压缩变形量、后悬压缩变形量求得前轴制动力比例;前悬压缩变形量Δf1,后悬压缩变形量Δf2,根据前悬压缩变形量、后悬压缩变形量的公式求得最优β,来抑制制动点头。本发明根据制动过程中,前轴轴荷增加,后轴轴荷降低,而轴荷比例决定了前后轴的极限能力;通过前后轴轴荷比例对制动力进行分配,可以提升制动过程中的操纵稳定性。
