Embodiment Construction

[0038] figure 1 A flow chart illustrating the method or configuration of the computer program 2 for setting the IUMPR or ratio of the vehicle 6 according to a preferred embodiment is shown. The flowchart can be viewed under the assumption that the diagnostic function requires one process sequence to recognize that the functional component 1 is functioning correctly and several process sequences to detect a faulty functional component 1 .

[0039] as in figure 1 As shown in FIG. 1 , an engine start of the internal combustion engine 4 of the vehicle 6 takes place first. This is recognized accordingly by the computer program 2 . It is then checked with the aid of physical operating parameters of the vehicle 6 such as rotational speed, load, engine temperature and / or exhaust gas temperature, whether the diagnostic function for determining the functionality of the functional components 1 of the vehicle 6 can be carried out or is operable. In the present example, functional compo...

Abstract

The present invention relates to a method for setting an IUMPR, a memory device, a controller, and a vehicle. Concretely, the invention relates to a method for setting an IUMPR of a vehicle, wherein the IUMPR comprises a numerator for indicating a number of possible sequences of diagnostic functions and a denominator for indicating a number of predefined operating states that have prevailed in thevehicle, wherein it is ascertained, on the basis of physical operating parameters of the vehicle, whether at least one diagnostic function can be carried out for ascertaining the functional capability of at least one function component of the vehicle, and then it is ascertained, depending on prevailing operating sequences in the vehicle and / or operating sequences yet to be carried out, whether adiagnostic mode of at least one function component for carrying out the at least one diagnostic function is available or can be set, such that the numerator of the IUMPR is incremented when it is detected that the diagnostic mode is available or can be set. The invention also relates to a computer program, a memory device, a controller and a vehicle.

Description

technical field [0001] The invention relates to a method, a computer program, a storage device, a controller and a vehicle, with which the IUMPR (English: In Use Motion PerformanceRatios (in English: In Use Motion PerformanceRatios) for setting the vehicle can be taken into account when required. Legal provisions on diagnostic functions with monitoring performance ratios)). Background technique [0002] In the case of a controller of an internal combustion engine, competing diagnostic functions or matching coordination are currently implemented. Competing diagnostic functions are to be understood as functions which, for example due to their system intervention, mutually exclude and / or influence each other, ie compete. With the aid of the controller and / or a suitably configured computer program, the diagnostic functions required by the legislator are coordinated centrally in terms of their practicability. [0003] In addition to the execution of diagnostic functions, the fr...
