Abstract
A method and a device for controlling a functional unit of a motor vehicle are provided. In the method, a function sequence is implemented in a functional program. The functional program is verified here by a safety program, which is in turn monitored by a monitoring module. Like the safety program, the functional program has a modular structure. The monitoring of the safety program is accordingly implemented in multiple stages corresponding to the number of modules.
