An axle torque distribution system includes a memory and a control module. The memory stores a steering angle and a torque distribution algorithm. The control module executes the torque distribution algorithm to: obtain the steering angle; determining a total lateral force requested for an axle of the vehicle based on the steering angle; determining a lateral force requested for the axles based on the requested total lateral force while constraining a lateral force distribution between the axles, where the constraining of the lateral force distribution includes: limiting the lateral force requested for the axles based on a maximum lateral force capacity of tires of the vehicle; determining available longitudinal capacities of the axles based on the lateral forces requested for the axles, respectively; determining torque capacities of the axles based on the lateral forces requested for the axles, respectively; and controlling distribution of torque to the axle based on the torque capacity of the axle.

    一种车轴转矩分配系统包括存储器和控制模块。所述存储器存储转向角和转矩分配算法。所述控制模块执行所述转矩分配算法以:获得所述转向角;基于所述转向角,确定针对车辆的车轴请求的总横向力;基于所请求的总横向力来确定针对所述车轴请求的横向力,同时约束所述车轴之间的横向力分配,其中所述横向力分配的约束包括:基于所述车辆的轮胎的最大横向力容量来限制针对所述车轴请求的所述横向力;基于分别针对所述车轴请求的所述横向力来确定所述车轴的可用纵向容量;基于分别针对所述车轴请求的所述横向力来确定所述车轴的转矩容量;以及基于所述车轴的所述转矩容量来控制对所述车轴的转矩的分配。
