A METHOD FOR CONTROLLING A HEAVY-DUTY VEHICLE

The present disclosure relates to a method for controlling a powertrain system (305) of a heavy-duty vehicle (100), said powertrain system having at least one differential arrangement (340) for receiving torque from a propulsion unit (330) of said powertrain system and delivering at least a part of said torque to a set of first and second wheels, said method being implemented by a control unit, said 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 said 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.
