  • Patent number: 11846244
    Abstract: A method for operating an injection valve by ascertaining an opening time and/or closing time of the injection valve on the basis of a sensor signal. The method includes: providing an analysis point time series by sampling a sensor signal of a sensor of the injection valve; using a nonlinear, data-based first submodel in order to obtain a first model output on the basis of the analysis point time series; using a linear, data-based second submodel in order to obtain a second model output on the basis of the analysis point time series; ascertaining the opening time and/or closing time as a function of the first and second model outputs.

  • Publication number: 20230313752
    Abstract: A method for training a data-based evaluation model to determine an opening or closing time of an injection valve based on a sensor signal. The method includes: measuring an operation of the injection valve in order to determine at least one sensor signal and an associated opening or closing time; sampling the sensor signal at a sampling rate in order to obtain a sensor signal time series with sensor signal values; determining a plurality of training data sets by assigning a plurality of evaluation point time series generated from a sensor signal time series to the opening or closing time associated with the sensor signal, wherein the evaluation point time series has a lower temporal resolution than the sensor signal time series; training the data-based evaluation model depending on the determined training data sets.

  • Publication number: 20230229121
    Abstract: A computer-implemented method for training a data-based time determining model for determining an opening or closing time of an injection valve based on a sensor signal. The method includes: providing an unlabeled analysis point time series by sampling the sensor signal of a sensor of the injection valve; training the data-based time determining model to assign a time specification which represents a specific opening or closing duration to an analysis point time series, the training process being carried out using a first shifting function to time-shift the analysis point time series and a second shifting function in order to time-shift the time specification. A consistency loss function is used for the training process.

  • Patent number: 9738029
    Abstract: A method for producing a molded body includes providing a composite including a first plate having a polymer film pressed into its surface, providing a third plate including roughened areas on at least part of one of its surfaces, placing the third plate opposite the polymer film without the third plate touching the composite, heating the third plate to a temperature above the glass transition temperature Tg of the polymer of the polymer film without heating the composite and without the heated third plate coming into contact with the surface of the polymer film, and structuring the surface of the polymer film facing the third plate by a relative movement which removes the third plate from the first plate while the polymer film remains soft and is thus extended lengthwise, thereby forming a modified composite that comprises the molded body.
