METHOD FOR CONTROLLING A HEAVY-DUTY VEHICLE

A method for controlling a powertrain system of a heavy-duty vehicle, the powertrain system having at least one differential arrangement for receiving torque from a propulsion unit of the powertrain system and delivering at least a part of the torque to a set of first and second wheels, the method being implemented by a control unit, the method comprising determining a split-friction condition indicative of a wheel slip difference between the first and second wheels, wherein one of the first and second wheels defines a high-friction side of the differential arrangement and the other one of the first and second wheels defines a low-friction side of the differential arrangement; determining a target wheel slip for the high-friction side; and in response to the determined split-friction condition; controlling a brake force on the low-friction side of the differential arrangement based on the target wheel slip on the high-friction side.
