Monitoring the functional reliability of an internal combustion engine
First Claim
1. A control device for an internal combustion engine system, comprising:
- a plurality of reliability-relevant functional units,wherein each reliability-relevant functional unit has;
at least one functional module, andat least one monitoring module associated with the at least one functional module,wherein each at least one functional module is separate from the associated at least one monitoring module, andwherein the at least one monitoring module is configured to monitor the at least one functional module, and each of the reliability-relevant functional units is computed on stand-alone hardware components;
a higher-order monitoring functional group;
wherein a particular one of the at least one monitoring module is configured to initiate an error processing responsive to detecting modules if an error in the at least one functional module associated with the particular monitoring module, wherein the error processing includes the particular one of the at least one monitoring module communicating with the higher-order monitoring functional group.

Abstract
An internal combustion engine is controlled by a plurality of partially reliability-relevant functional units. Every reliability-relevant functional unit comprises at least one functional module and at least one monitoring module. The monitoring module is separate from the functional module associated therewith and monitors the functioning of the functional module. The control device also comprises a higher order monitoring functional group. The monitoring module has an entry point for communication with the higher order monitoring functional group. When an error is detected, the monitoring module signals the error to the higher order monitoring functional group using the entry point.
