A control unit for controlling a heavy-duty vehicle is arranged to obtain an initial inverse tire model configured to represent a preliminary relationship between wheel slip and generated longitudinal wheel force for at least one wheel of the heavy-duty vehicle. The control unit obtains data from a tire thread deflection sensor configured to measure an amount of tire thread deflection associated with the at least one wheel, and an amount of wheel slip of the at least one wheel corresponding to the amount of tire thread deflection. The control unit updates the obtained initial inverse tire model based on the amount of tire thread deflection and on the corresponding amount of wheel slip. The control unit controls the heavy-duty vehicle by configuring a target wheel speed or a target wheel slip of the at least one wheel based on the updated inverse tire model to generate a target longitudinal wheel force.
