The invention relates to a computer architecture and functional architecture for the operation of electric power steering, to an electronic control unit, and to power steering, having a first group of modules with a high probability of failure and a second group of modules with a low probability of failure. In this case, the modules of the first group have a higher probability of failure than the modules of the second group. The first group of modules is maintained redundantly in this case and, as a result, divided into main modules and into the redundant implementation of what are known as secondary modules. The main modules are arranged on a main control path and the secondary modules are respectively arranged on a secondary control path. Each of these control paths ultimately produces a control signal, i.e., a main control signal and a secondary control signal. A multiplexer is used to decide which of these two control signals is forwarded to modules from the second group. This second group of modules is implemented only once and not present in redundant form.
