Abstract: A method performed by a first sensor device registered with a processing node via a network comprises steps of: i. detecting a trigger event, ii. broadcasting a signal to a second sensor device and establishing a direct connection between the first sensor device and the second sensor device, iii. transferring identity information and connection information to the second sensor device via the direct connection, the former identifying the first sensor device to the processing node, the latter being used by the first sensor device to connect to the processing node, and iv. receiving confirmation that the second sensor device has been registered with the processing node as a replacement for the first sensor device and removing the connection information from the first sensor device.

Abstract: 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.

Abstract: A method for control of braking by a supplementary brake (290-296) of a motor vehicle (100; 110): Choose (s410) supplementary braking by a control device (270). Continuously determine 20) total available supplementary brake torque (Mtot) and determine (s430) by the control device (270) a chosen proportion (Mshare) of total available supplementary brake torque (Mtot). Determine (s440) a supplementary brake torque (Mtot*) corresponding to the chosen proportion share) and apportion (s450) supplementary brake torque determined (Mtot*) to a chosen supplementary brake (290-296). A computer program (P) implements the method. A device controls braking by a supplementary brake (290-296). A motor vehicle (100; 110) is equipped with the device.
