ERROR CAUSE DETECTION OR NARROWING DOWN OF ERRORS WITH THE AID OF ERROR PATTERNS IN THE AIR SYSTEM
First Claim
1. A method for monitoring at least one part of an internal combustion engine based on a variable whose values characterize the operation of the part of the internal combustion engine during different states of the internal combustion engine, comprising:
- determining an actual pattern with actual values of the variable during different states of the internal combustion engine which describe the actual operation of the internal combustion engine;
providing a reference pattern for a known operation of the internal combustion engine, the reference pattern including reference values of the variable for different states of the internal combustion engine; and
comparing the actual pattern to the reference pattern to determine a similarity between the actual operation and the known operation.

Abstract
A method for monitoring at least one part of an internal combustion engine based on a variable whose values characterize the operation of the part of the internal combustion engine during different states of the internal combustion engine, including: determining an actual pattern with the actual values of the variable during different states of the internal combustion engine which describe the actual operation of the internal combustion engine; providing a reference pattern for a known operation of the internal combustion engine, the reference pattern including reference values of the variable for different states of the internal combustion engine; and comparing the actual pattern to the reference pattern to determine a similarity between the actual operation and the known operation.

2. A device for monitoring at least one part of an internal combustion engine based on a variable whose values characterize the operation of the part of the internal combustion engine during different states of the internal combustion engine, comprising:
-
an observation device for outputting an actual pattern with actual values, detected by the observation device, of the variable during different states of the internal combustion engine which describe the actual operation of the internal combustion engine; a memory to store a reference pattern for a known operation of the internal combustion engine, the reference pattern including reference values of the variable for different states of the internal combustion engine; and an evaluation device to compare the actual pattern to the reference pattern to determine a similarity between the actual operation and the known operation. - View Dependent Claims (3, 4, 5, 6, 7, 8)
