1. A method for controlling a vehicle brake system for a heavy duty vehicle, the brake system comprising a primary brake system and an auxiliary brake system, the method comprising:
configuring a wheel slip magnitude limit,
obtaining a requested auxiliary brake torque,
engaging the primary brake system at a torque determined in dependence of the requested auxiliary brake torque, while
monitoring a wheel slip value,
determining an allowable auxiliary brake torque in dependence of the requested auxiliary brake torque and the monitored wheel slip value, and
engaging the auxiliary brake system at the allowable auxiliary brake torque.
