The invention provides a method for determining an optimized torque distribution for a wheel of a road vehicle and an associated road vehicle, the method comprising the steps of: determining a table (ST) of torque distribution between a front axle (FA) and a rear axle (RA); determining a second table (ST '') and a third table (ST'' ') of torque distribution between the respective right and left wheels (2, 3) of the rear axle (RA) and the front axle (FA); detecting a current longitudinal dynamic characteristic (Ax, Vx); using the first, second and third tables (ST ', ST' ', ST' ''), current values of the first, second and third distribution coefficients (AWDS, RLS, and RLS ') are determined, respectively, on the basis of the current longitudinal velocity (Vx) and current longitudinal acceleration (Ax) of the road vehicle (1).
本发明提供一种用于确定道路车辆的车轮的优化的扭矩分配的方法和相关的道路车辆,所述方法包括以下步骤:确定前车轴(FA)和后车轴(RA)之间的扭矩的分配的表(ST);确定后车轴(RA)和前车轴(FA)各自的右车轮(2、3)和左车轮(2、3)之间的扭矩分配的第二表(ST”)和第三表(ST”’);检测当前纵向动态特性(Ax、Vx);使用第一表、第二表和第三表(ST’、ST”、ST”’),基于道路车辆(1)的当前纵向速度(Vx)和当前纵向加速度(Ax)分别确定第一分配系数(AWDS)、第二分配系数(RLS)和第三分配系数(RLS’)的当前值。
