Abstract:
1. A method for controlling a functional unit of a motor vehicle, comprising: implementing a function sequence for the functional unit by a functional program, wherein the functional program has a modular organizational structure including at least two functional modules; verifying the functional program by a safety program, wherein the safety program has a modular organizational structure including at least two safety modules corresponding to the at least two functional modules; and monitoring the safety program by a monitoring module, wherein the monitoring of the safety program is implemented in multiple parts corresponding to the number of safety modules; wherein the at least two safety modules of the safety program each generate a partial contribution as output, and wherein the partial contributions are fed to the monitoring module for evaluation; and wherein the partial contributions are initially provided from the at least two safety modules to a decoder, and wherein the partial contributions are fed to the monitoring module from the decoder.
