Abstract
A control device of the internal combustion engine has a first arithmetic unit and a second arithmetic unit. The arithmetic units process a control program with a first, second and third program level. In the second program level an actuation signal is monitored, and a first emergency operating function is activated in the first program level if the second program level has detected an implausibility of the actuation signal. The third program level is caused to carry out a second emergency operating function if, while the first emergency operating function is being carried out in the first program level, the implausibility of the actuation signal continues to be detected.
