A computer-implemented method for reducing a lateral drift of a heavy-duty vehicle (100) due to a road bank angle (ϕ), where the heavy-duty vehicle is associated with a non-zero understeer/oversteer gradient (Ku). The method comprises: obtaining (S1) a road bank angle (ϕ) of a road section (211) the heavy-duty vehicle (100) is about to traverse; obtaining (S2) a vehicle model indicative of a vehicle motion response to the road bank angle (ϕ), where the vehicle model includes the understeer/oversteer gradient (Ku); determining (S3), based on the road bank angle (ϕ) and the vehicle model, a first compensation torque (Tc) for reducing the lateral drift of the heavy-duty vehicle (100) at the road section (211); and applying (S4) the first compensation torque (TC) across different wheels (140) of the heavy-duty vehicle (100) to reduce the lateral drift of the heavy-duty vehicle due to the road bank angle (ϕ).
