Abstract

At least one operating quantity of an internal combustion engine is recorded. A criterion is derived for an oil change from the at least one operating quantity by converting a number of operating quantities, as input quantities of a neural and/or probabilistic computer network, into a number of state quantities characterizing the oil as output quantities of the computer network, wherein at least some of the output quantities are subjected to a check, the criterion being derived from the check.

Claims

1-18. -18. (canceled)

19. A method, comprising:

recording at least one operating quantity of an internal combustion engine; and

deriving a criterion for an oil change from the at least one operating quantity by converting a number of operating quantities, as input quantities of a neural and/or probabilistic computer network, into a number of state quantities characterizing the oil as output quantities of the computer network, wherein at least some of the output quantities are subjected to a check, the criterion being derived from the check.

34. A system, comprising:

at least one sensor configured to record at least one operating quantity relevant to oil deterioration;

a computing device configured to derive a criterion for an oil change from the at least one operating quantity, the computing device including a neuronal and/or probabilistic computer network with inputs for input quantities in the form of operating quantities, the network being configured to convert the input quantities to state quantities characterizing the oil as output quantities, the network including contains comparison and logic units designed to subject the output quantities to a check and to derive the criterion from the checking of all output quantities.

35. The system of claim 34, further comprising an output device to output information concerning an oil change as a function of a criterion.

36. The system of claim 35, further comprising an internal combustion engine, having an electrical device for control and/or regulation of the internal combustion engine according to the information.
