20080221773 | Method for the automatic determination of the quality of a transition compensation - To achieve a better compensation of the wall film effect in the operation of a gasoline engine as well as an objective evaluation of the quality of the transition compensation, the characteristic of Lambda values and a load are automatically detected in a test phase during an operation of the gasoline engine having activated transition compensation. Relevant load changes are automatically extracted as a function of the ascertained characteristics and classified as a function of specifiable criteria. For each load change extracted, at least one quality value is automatically determined as a function of a deviation of the at least one assigned Lambda value from at least one specifiable Lambda value. Each ascertained quality value is then weighted as a function of the implemented classification. Subsequently, an overall quality is calculated from the weighted quality values. At least one statistical method is used for this purpose. | 09-11-2008 |
20120185146 | METHOD AND DEVICE FOR AUTOMATICALLY PRODUCING MAP CHARACTERISTIC CURVE STRUCTURES FOR REGULATING AND/OR CONTROLLING A SYSTEM, IN PARTICULAR AN INTERNAL COMBUSTION ENGINE - A method for the automatic production of map characteristic curve structures for regulating and/or controlling a system. A modeling approach being used for the acquisition of causal dependencies from which, based on measurement data, a map characteristic curve structure is derived. In order to achieve an optimal map characteristic curve structure, the modeling approach has a theoretical data model from which a theoretical model deviation is determined, at least one input quantity of the data model being supplied to a map structure producer for determining a map characteristic curve structure, and the determined map characteristic curve structure being parameterized using measurement data and the result of the parameterization being compared to the theoretical model deviation, and, if a result of the comparison exceeds a specified value, the result of the comparison being resupplied to the map structure producer for the adaptation of the map characteristic curve structure. | 07-19-2012 |
20120283848 | METHOD FOR ASCERTAINING FUNCTIONAL PARAMETERS FOR A CONTROL UNIT - A method for ascertaining functional parameters for a control unit and to a control unit in which the provided method is carried out. The control unit is provided for controlling a technical system wherein, in the method, at least one target variable on a system response is specified and a variation of the functional parameters is carried out, from a response received to the functional parameters, a valuation being carried out of the set functional parameters while taking into account the at least one specified target variable. | 11-08-2012 |
