A method and a system to control an auxiliary brake system in a vehicle 100 having a service brake system 150 and an auxiliary brake system 160. Also a system for prevention of wheel lock when braking, which may deactivate a braking action provided by the auxiliary brake system 160 and may actively control a braking action provided by the service brake system 150. The system determines whether the vehicle 100 is in a driving mode for which it is acceptable in terms of safety and/or drivability to block the deactivation of the braking action for the auxiliary brake system 160. If a first manual control 170, which is set up solely for activating braking action for the auxiliary brake system 160, is activated, this means it is acceptable, from a safety and/or drivability point of view, for the driving mode in question, to block the deactivation. Also arranging block deactivation for the auxiliary brake system 160 if it is acceptable in terms of safety and drivability to block it. |
