A method for distributing and/or updating software in interconnected control devices, in particular those of a motor vehicle, involves; storing at least one factory-side preprogrammed base module for the initialisation and programming of one of a plurality of programmable sub-control devices, forming part of an interconnected system of control devices, in a respective first storage region of each sub-control device; storing factory-side preprogrammed operating modules for all of the plurality of programmable sub-control devices of the interconnected sub-system in at least one main control device, in turn forming part of the interconnected sub-system of control devices, in second storage region of the main control device, at a predetermined time; and/or optionally transmitting at least one operating module, provided for at least a determined one of the plurality of programmable sub-control devices, independently from the main control device to the at least one determined sub-control device; and independently and operationally programming the at least one determined sub-control device with the at least one operating module received from the main control device, using the base module. An underlying system can be an electronic brake system of a vehicle, in which the main control system forms a central and/or a master device, which is connected via a CAN bus as a network to at least one wheel pressure regulation module (EPM), a foot brake module (FBM) and/or a trailer control module (TCM) as programmable sub-control devices, each forming slave devices. |
