Abstract
In the case of a control system for adjusting devices of a motor vehicle which, in addition to a basic mechanical function, carries out an additional function which can be achieved by electronic devices, having at least one sensor for an input value, one computer for converting the input value to an output value for a control element assigned to the additional function, and having an emergency device for an emergency measure in the case of an occurrence of a failure, the measures according to the invention are that a function chain consisting of the function step sensor(s), the computer(s) and an emergency device assigned to the control element, in contrast to the singly existing control element, have a redundant construction, that the elements of the function chains, which have the same effect, are monitored with respect to the same effect, and in that the emergency measure is triggered, when elements of the function chains which have the same effect exhibit a deviation by a given measurement.
