Definitions
- the invention relates to a method for determining functional parameters for a control unit and such a control unit.
- control unit functions that are implemented in the control units used must be designed according to requirements with regard to the target parameters or evaluation criteria of the manufacturer and the end customer via functional parameters.
- control unit functions make it possible to determine fixed settings by means of a parameter set, in many cases also by means of several parameter sets, via constants, characteristic curves and characteristic diagrams. It should be noted that the complexity of the functions and thus the number of maps is constantly increasing. Function specialists who know the influence of each parameter at best can interpret the functions according to the requirements of the customer.
- the method enables an application by directly specifying objective target values or criteria for a function in the control unit.
- the invention makes possible an application by setting target variables, in which case the concentration is the target variables and not the functional parameters. This leads to a reduction in complexity for the user, especially since no function specialist is necessary for the vote.
- the presented procedure allows a systematic approach with objective evaluation of the settings. Furthermore, recursions are necessary for adjustment. solution is less costly. Optionally, a reduction of map structures in the control unit can be achieved.
- control unit function it is possible to develop a control unit function or to extend existing control unit functions, so that they apply independently.
- the function goals are specified by the applicator or customer in design via one or more weighting characteristics of the target variables or criteria.
- the function learns the necessary internal function parameters.
- Figure 1 shows a schematic representation of a possible embodiment of the method described.
- FIG. 2 shows a further possible embodiment of the method.
- FIG. 1 outlines a method sequence which directly performs parameter variations, such as, for example, function parameters, on a target system or system 10 and in which the system 10 is operated at different operating points.
- criteria are calculated from the system 10 in a step 12.
- a mathematical model or criteria model 14 is formed, which creates the dependencies of the target variables and criteria from the parameters.
- An optimizer 16 may optimize on the basis of the given weighting criteria from a weighting map 18 on this model 14 and determine the optimal function parameters 20 and provide them to the actual functions of the controller 22 and update them again and again, the optimizer 16 is a development of system responses or can take into account the criteria calculated on the system responses, for example by a gradient analysis or evaluation.
- the system 10 thus initially moves with start parameters of the control unit function. In doing so, the system 10 is operated at any operating point with the adjusted function parameters 20, providing outputs on which criteria are calculated. With these criteria, the criteria or behavioral model 14 is created.
- the optimizer 16 determines the optimal parameters with a given weighting in the measured range of the behavioral model 14 and changes the corresponding function parameters with the results.
- system 10 initially uses function parameters which have been specified or accepted, for example. However, these are not usually tuned to the system 10, i. that these are not optimal for the system 10.
- the behavioral model 14 usually does not exist. However, it is also possible to deposit a behavioral model 14 of a similar system 10.
- the system 10 is then operated at different operating points and thereby learns its own behavior at different operating points.
- the optimizer 16 of the function specifies parameter combinations representing a prediction of the optimizer 16 with respect to an improvement of the behavioral model 14.
- parameter combinations are tried which are intended to improve the behavior of the system 10.
- the behavior model 14 is extended by the criteria and the parameter combination. With the extended parameter combination and the associated criteria, a new extended behavioral model 14 is calculated.
- the optimizer 16 uses the behavior model 14 and checks whether the parameter specification has led to the improvement or deterioration of the behavior of the system 10. As a result, the optimizer 16 gradually determines the combination of parameters in which the optimal behavior of the system 10 is established with respect to the criteria. This is done in an iterative process in which the behavioral model 14 grows until the optimal behavior is found. This is done for each operating point.
- the optimizer 16 determines each of the optimal parameters of the behavioral model 14 in the measured range and gives a forecast on whether a further improvement of the behavior can be achieved.
- the task of the optimizer 16 is to evaluate the criteria of the behavioral model 14 according to the prediction from the weighting maps.
- the specification to the optimizer 16 may be a summation criterion of weights for which the optimizer 16 finds only a solution of the parameters.
- the function may be designed such that the optimizer 16 delivers a multitude of function parameters 20 via multi-objective optimization and the function parameter selection takes place via the weighting of the criteria from a memory or model of optimal parameters. In this case, after learning the criteria model 14, the weighting criteria can be shifted at any time. The function parameters 20 take effect immediately. The user can apply in this way without having to know the function parameters 20.
- the weightings can be changed at any time, for example by switching different weighting maps or by controlling directly on the weightings.
- FIG. 2 shows a procedure similar to that in FIG. 1, with the difference that parameters are not varied directly on a system 30, but rather via an intermediate model 32, in order to avoid noticeable influences of the variations.
- the intermediate model 32 replaces the system 30 and is aligned with the system 30 under defined conditions by identification, optimization, or other computations (block 35).
- criteria from the intermediate model 32 are calculated in a step 34.
- a mathematical model or criteria model 36 is then formed from the calculated criteria and target variables, which creates the dependencies of the target variables and criteria on the parameters.
- An optimizer 38 can then optimize by providing weighting criteria from a weighting map 40 on this model 36 and determine the optimal function parameters 42 and make them available to the actual ECU functions 44 and keep updating. The optimization can also be calculated in the wake of the control unit.
- a particular advantage is that the ECU software does not have to be changed. It should be noted, however, that different setups or regu- can not be implemented on the weightings. Furthermore, an additional tool must be available for the application and also for the customer.
