A torque vectoring method for a vehicle is disclosed. A computer-implemented method for reducing lateral offset of a heavy vehicle (100) due to a road tilt angle (phi), wherein the heavy vehicle is associated with a non-zero understeer/oversteer gradient (Ku). The method comprises: obtaining (S1) a road inclination angle (phi) of a road section (211) through which the heavy vehicle (100) is to pass; obtaining (S2) a vehicle model indicative of a vehicle motion response to the road inclination angle (phi), wherein the vehicle model comprises an understeer/oversteer gradient (Ku); determining (S3) a first compensation torque (TC) for reducing a lateral offset of the heavy vehicle (100) at the road section (211) based on the road inclination angle (phi) and a vehicle model; and applying (S4) a first compensation torque (TC) on different wheels (140) of the heavy vehicle (100) to reduce lateral offset of the heavy vehicle due to the road tilt angle (phi).

    公开了用于车辆的扭矩矢量控制方法。一种用于减小由于道路倾斜角度(φ)引起的重型车辆(100)的横向偏移的计算机实现方法,其中重型车辆与非零转向不足/转向过度梯度(Ku)相关联。该方法包括:获得(S1)重型车辆(100)将要经过的道路区段(211)的道路倾斜角度(φ);获得(S2)指示对道路倾斜角度(φ)的车辆运动响应的车辆模型,其中该车辆模型包括转向不足/转向过度梯度(Ku);基于道路倾斜角度(φ)和车辆模型来确定(S3)用于减小重型车辆(100)在道路区段(211)处的横向偏移的第一补偿扭矩(TC);以及在重型车辆(100)的不同车轮(140)上施加(S4)第一补偿扭矩(TC),以减小由于道路倾斜角度(φ)引起的重型车辆的横向偏移。
