A method for indirectly deriving a systematic dependence for a system behavior of a system component of a cleaning system of a motor vehicle, wherein the cleaning system is adapted for a resource-saving cleaning of at least one surface of the motor vehicle by means of a cleaning process whereby an output quantity depends on an input quantity by means of the system behavior, the method comprising steps of:
- determining, by a computing device of the motor vehicle, the input quantity as a first parameter of the method via at least one of a plurality of sensors;
- determining, by the computing device of the motor vehicle, the output quantity as a second parameter of the method via at least one of the plurality of sensors;
- digitalizing and recording, by the computing device of the motor vehicle, the determined first parameter and the second parameter by a data processing system including an electronic data processing and evaluation system and a database;
- storing, by the computing device of the motor vehicle, the determined first parameter and the second parameter in an ordered manner with reference to one another in the database as a data set of a dependency table;
- deriving, by the computing device of the motor vehicle, the systematic dependence between the first parameter and the second parameter via the electronic data processing and evaluation system from at least two data sets of the dependency table stored in the database whereby the electronic data processing and evaluation system accesses the at least two data sets of the dependency table and determines the systematic dependence using the at least two data sets of the dependency table;
- storing, by the computing device of the motor vehicle, the derived systematic dependence in one or more of the database the electronic data processing and evaluation system, or an electronic control unit;
- and
- controlling an operation of the cleaning system of the motor vehicle based on the derived systematic dependence.
A method for diagnosing a system behavior of a system component of a cleaning system of a motor vehicle, wherein an output quantity depends on an input quantity by means of the system behavior, and wherein exceeding an upper threshold quantity by an actual output quantity or falling below a lower threshold quantity by the actual output quantity indicates that an actual system behavior deviates from an expected system behavior, wherein the method comprises steps of:
- determining the input quantity based on first data from at least one of a plurality of sensors of the motor vehicle, wherein the input quantity is an availability or a gain of availability of the at least one of the plurality of sensors;
- determining the actual output quantity based on second data from the at least one of a plurality of sensors, wherein the actual output quantity is a resource requirement of a cleaning process;
- digitizing and storing, by a computing device of the motor vehicle, the input quantity and the actual output quantity by a data processing system including an electronic data processing and evaluation system and a database, wherein the storing is based at least in part on the input quantity and the actual output quantity being in an ordered manner with reference to the lower threshold quantity and the upper threshold quantity as a data set of a dependency table;
- retrieving the upper threshold quantity or the lower threshold quantity based on the input quantity;
- comparing the actual output quantity with the upper threshold quantity and the lower threshold quantity;
- calculating a deviation between the actual output quantity and the upper threshold quantity in response to the actual output quantity exceeding has exceeded the upper threshold quantity, and calculating a deviation between the actual output quantity and the lower threshold quantity in response to the actual output quantity being has fallen below the lower threshold quantity, wherein calculating the deviation is based at least in part on the electronic data processing and evaluation system comparing the data set from the dependency table;
- determining a resolution strategy in response to the deviation, the resolution strategy comprising an input quantity that influences operation of one or more system components of the cleaning system;
- storing a diagnostic signal, if the actual output quantity exceeds the upper threshold quantity or if the actual output quantity falls below the lower threshold quantity;
- reporting an abnormal system behavior of the system component of the cleaning system of the motor vehicle based on the diagnostic signal;
- and
- controlling the operation of the one or more system components of the cleaning system in response to the diagnostic signal or the abnormal system behavior and based on the input quantity.
